for every 10 clovers that lucy picked, 3 of them had four leaves, while the others only had three leaves. in total, lucy picked 100 clovers. if her pattern continued, how many three-leaf and four-leaf clovers would lucy have?

how many of each clover would she have if she picked 200 clovers?

I need help! first to answer and the best answer will get 100 point and get to get 5 more if it is the best

Answers

Answer:

100 = 30 (four-leaf) + 70 (three-leaf);200 = 60 (four-leaf) + 140 (three-leaf).

--------------------------------------

Every 3 clovers out of 10 have four leaves and the rest 7 have three leaves.

This gives us the ratio of clovers with four leaves by the total number:

3/10 or 0.3

If the total number is 100, then Lucy has:

100*3/10 = 30 four-leaf and 70 three-leaf clovers

If there are 200 clovers, then the number of four-leaf clovers is doubled:

30*2 = 60 and the number of three-leaf clovers is70*2 = 140

Find an equation of the line that satisfies the given conditions. Through (-9, -11); perpendicular to the line passing through (-6, 1) and (-2, -1)
Find an equation of the line that satisfies the given conditions.
Through (−9, −11); perpendicular to the line passing through (−6, 1) and (−2, −1)

Answers

An equation of the line that satisfies the given conditions is x = 2y + 13.

To find the equation of the line that passes through the point (-9, -11) and is perpendicular to the line passing through (-6, 1) and (-2, -1), we can use the slope-point form of a line.

First, we find the slope of the line passing through (-6, 1) and (-2, -1). The slope of this line can be found using the formula:

m = (y2 - y1) / (x2 - x1)

where (x1, y1) and (x2, y2) are the coordinates of the two points.

Plugging in the values, we have:

m = (-1 - 1) / (-2 - (-6)) = -2 / 4 = -1/2

The slope of a line perpendicular to this line has a negative reciprocal, so the slope of the line through (-9, -11) that is perpendicular to this line is 1/2.

Next, we use the point-slope form of a line to find the equation of the line:

y - y1 = m (x - x1)

where (x1, y1) is a point on the line and m is the slope.

Plugging in the values, we have:

y - (-11) = 1/2 (x - (-9))

Expanding and simplifying, we get:

y + 11 = 1/2 (x + 9)

Multiplying both sides by 2, we get:

2y + 22 = x + 9

Subtracting 9 from both sides, we get:

2y + 13 = x

So, the equation of the line that satisfies the given conditions is:

x = 2y + 13

Rhea wants to purchase a new home house. The house on main street requires a $10,000 down payment and will be a $900 a month on the loan. the other house she likes on Empire Road who has a $4000 down payment and is $1050 per month. Which house has a greater rate of change and what is it? Which house had a greater initial value and what is it?

Answers

Answer:

Step-by-step explanation:

First, we'll write the cost equations for each house, using the number of months since the initial purchase as the independent variable X:

For the house on Main Street:

Cost = 900X + 10,000

For the house on Empire Road:

Cost = 1050X + 4000

Next, we'll find the rate of change for each house by finding the slope of the respective cost equation:

The slope of the cost equation for the house on Main Street is 900. This means that for every month that passes, the cost of the house will increase by $900.

The slope of the cost equation for the house on Empire Road is 1050. This means that for every month that passes, the cost of the house will increase by $1050.

Now that we have found the rate of change for each house, we can compare them to determine which house has the greater rate of change:

Since the slope of the cost equation for the house on Empire Road is greater than the slope of the cost equation for the house on Main Street (1050 > 900), the house on Empire Road has a greater rate of change.

Finally, we can compare the initial values of each house by comparing the y-intercepts of the respective cost equations:

The y-intercept of the cost equation for the house on Main Street is 10,000, which means that the initial cost of the house is $10,000.

The y-intercept of the cost equation for the house on Empire Road is 4000, which means that the initial cost of the house is $4,000.

Since the y-intercept of the cost equation for the house on Main Street is greater than the y-intercept of the cost equation for the house on Empire Road (10,000 > 4,000), the house on Main Street has a greater initial value.

The graph has to start at  - 4   and get  smaller ( more negative...'less than')   but NOT INCLUDE -4   ( should be hollow dot at -4)

Let f(x)=sin(x) + 2 cos(x). Find the slope-intercept equation of the line tangent to the graph of y = f(x) at the point on the graph where x = 0. The equation of the tangent line is (write your answer in the form y =mx+b):​

Answers

Answer:

Step-by-step explanation:

The first step is to find the slope of the tangent line. To do that, we need to find the derivative of f(x):

f(x) = sin(x) + 2cos(x)

f'(x) = cos(x) - 2sin(x)

Now we can find the slope of the tangent line at x=0 by plugging in x=0 into f'(x):

f'(0) = cos(0) - 2sin(0) = 1

Therefore, the slope of the tangent line at x=0 is 1.

Next, we need to find the y-coordinate of the point on the graph where x=0. To do that, we simply plug in x=0 into f(x):

f(0) = sin(0) + 2cos(0) = 2

Therefore, the point on the graph where x=0 is (0, 2).

Now we can use the point-slope form of the equation of a line to find the equation of the tangent line:

y - y1 = m(x - x1)

where m is the slope and (x1, y1) is the point on the line. Plugging in m=1 and (x1, y1) = (0, 2), we get:

y - 2 = 1(x - 0)

Simplifying, we get:

y = x + 2

Therefore, the equation of the tangent line is y = x + 2.

Answer:

The equation of the tangent line at x = 0 can be found by differentiating the function f(x) and using the point-slope form of a line.

The derivative of f(x) is f'(x) = cos(x) - 2sin(x). Substituting x = 0 into f'(x) gives f'(0) = cos(0) - 2sin(0) = 1 - 0 = 1.

Therefore, the equation of the tangent line is y = 1x + b, or y = x + b.

To find the value of b, we can plug in x = 0 and y = f(0) = sin(0) + 2cos(0) = 2 into the equation. Solving for b, we get 2 = 0 + b, so b = 2.

Therefore, the slope-intercept equation of the line tangent to the graph of y = f(x) at the point (0,2) is y = x + 2.

0.4 = 0.167 + 0.2 v.. find the value of v?

Answers

Answer:

v = 1.165

Step-by-step explanation:

To find the value of v in the equation 0.4 = 0.167 + 0.2v, we can isolate v by subtracting 0.167 from both sides:0.4 - 0.167 = 0.2v0.233 = 0.2vNext, we can divide both sides by 0.2 to find the value of v:0.233 / 0.2 = 0.2v / 0.2v = 0.233 / 0.2v = 1.165So the value of v is 1.165.In conclusion, by subtracting 0.167 from both sides of the equation and dividing both sides by 0.2, we found that the value of v is 1.165.

Answer: The value of v that satisfies the equation 0.4 = 0.167 + 0.2v is 1.165.

Step-by-step explanation:

To find the value of v in the equation 0.4 = 0.167 + 0.2v, we can isolate v by subtracting 0.167 from both sides:

0.4 - 0.167 = 0.2v

0.233 = 0.2v

Next, we can divide both sides by 0.2 to solve for v:

0.233 / 0.2 = 0.2v / 0.2

v = 1.165

So, the value of v that satisfies the equation 0.4 = 0.167 + 0.2v is 1.165.

A plastic rod has been bent into a circle of radius R = 8.20 cm. It has a charge Q1 = +3.00 pC uniformly distributed along one-quarter of its circumference and a charge Q2 = -6Q1 uniformly distributed along the rest of the circumference. Take V = 0 at infinity.

Answers

The electric potential at the center of the circle formed by the plastic rod is -1.644V.

We know that the formula to find the electric potential V = KQ/R,

where K is Coulombs constant, Q is the charge, and R is the radius of the circle.  

According to the question,

The radius of the circle formed by the plastic rod on bending = 8.20 cm

(Converting cm to m by dividing by 100)               = (8.20)/100 = 0.082m

We know that Coulombs constant (K) =  8.99 × 10 ^ 9 N m^2/C^2

It is given that along one quarter of its circumference (Q1) =  +3.00 pC

and along the remaining circumference, the charge (Q2) = -6Q1

Therefore, electric potential (V) = K (Q1+KQ2) /R

= (8.99 × 10 ^ 9) (Q1 + (-6Q1)) / 0.082 = (8.99 × 10 ^ 9) (-5Q1)/ 0.082

= -5 (8.99 × 10 ^ 9) (3 X 10 ^ -12) / (0.082) = -1.644512V ≈ -1.644V

The given question is incomplete, the complete question is:

How to calculate MLB magic number?

Answers

The formula to calculate the magic number in MLB is: Magic number = 163 - (number of wins by leading team) + (number of losses by trailing team) - 1.

The "magic number" in Major League Baseball (MLB) represents the combination of wins by the leading team and losses by the trailing team required for the leading team to clinch a playoff spot. To calculate the magic number, follow these steps:

1. Determine the total number of games in the season. In MLB, this is typically 162 games.

2. Subtract the number of games in the season from 163. For example, 163 - 162 = 1.

3. Subtract the number of wins by the leading team from 163. For example, if the leading team has 90 wins, 163 - 90 = 73.

4. Add the result from step 2 to the result from step 3. For example, 73 + 1 = 74.

5. Finally, subtract the number of losses by the trailing team from the result of step 4. For example, if the trailing team has 80 losses, 74 - 80 = -6. In this case, the magic number is zero, meaning that the leading team has already clinched a playoff spot.

For this we will use the concept of division,

The number of ribbon cut from it = total length / small ribbons length

= 35 /  [tex]1\frac{2}{3}[/tex]

= 35 / 5÷3

= 35×3 / 5

= 21

Hence, the number of ribbons of length  [tex]1\frac{2}{3}[/tex]  that can be cut out of a piece of ribbon that is 35 ft long, is 21

Ms Shaws class is studying the life cycle of a fish Ms shaw has 16 fish her fish hold 3 fish each how many fish tanka does Ms Shaw completely fill? How many fish are left?

Answers

Answer:

So Ms. Shaw will completely fill 6 fish tanks and have 1 fish left.

Step-by-step explanation:

Ms. Shaw has 16 fish and each fish tank can hold 3 fish. To find out how many fish tanks she needs, we can divide the total number of fish by the capacity of each tank:

16 fish / 3 fish per tank ≈ 5.33 tanks

Since we cannot have a fraction of a tank, we need to round up to the nearest whole number. Therefore, Ms. Shaw needs 6 fish tanks to completely fill all her fish.

To find out how many fish are left, we need to subtract the number of fish in the full tanks from the total number of fish:

16 fish - (5 tanks * 3 fish per tank) = 1 fish left

So Ms. Shaw will completely fill 6 fish tanks and have 1 fish left.

A student received a coupon for 13​% off the total purchase price at a clothing store. Let x be the original price of the purchase. Use the expression below for the new price of the purchase. Write an equivalent expression by combining like terms.
x−0.13x

Answers

The new price of the purchase after the 13% discount can also be expressed as 0.87x.

The new price of the purchase after the 13% discount is expressed as x - 0.13x.

We can factor out x as follows to simplify this expression by combining like terms:

x - 0.13x = x(1 - 0.13) (1 - 0.13).

We can simplify the expression in parentheses as follows:

1 - 0.13 = 0.87.

So, by combining like terms, the equivalent expression is:

x - 0.13x = 0.87x.

As a result, the new purchase price after the 13% discount can also be expressed as 0.87x.

it Is Impossible To Get 8 Aces When Selecting Cards From A Shuffled Deck. Express The Indicated Degree Of Likelihood As A Probability Value Between 0 And 1 Inclusive. The Probability Is (Type An Integer Or A Decimal.)

Answers

It is impossible to get 8 aces from a standard 52 cards deck.

What is probability and its formula?

The formula for probability states that the possibility of an event happening, or P(E), equals the ratio of the number of favorable outcomes to the number of total outcomes. Mathematically, it looks like this: P(E) = favorable outcomes/total outcomes.

Now, According to the question:

There are four aces in total in a 52 card deck.

Therefore the probability of getting 8 aces can be expressed as:

P(8A) = 7/52 × 6/51 × 5/50 × 4/49 × 3/48 × 2/47 × 1/46 × 0/45 = 0

The probability getting is zero.

Therefore, it is impossible to get 8 aces from a standard 52 cards deck.

Which of the following is not a characteristic of the normal distribution?1.The total area under the curve is 1.02. The two tails of the curve extend indefinitely3. The value of the mean is always greater than the value of the standard deviation4.The curve is symmetric about the mean

Answers

" The value of the mean is always greater than the value of the standard deviation" is not a characteristic of the normal distribution

The curve of a normal distribution is known as the bell curve. The curve in statistical analysis represents the occurrence of some particular result as a product of the experiment. The normal curve is always symmetrical. This implies that the results of the trials will produce results near the mean value of the distribution.

Characteristics of a normal distribution involve:

1. The total area beneath the symmetric curve is 1: Since the area under the curve represents the chances of all the experiments; hence the summation must be 1.

2. The two tails of the curve extend indefinitely: The tails of the normal distribution never touch the horizontal axis; it is extended indefinitely.

4. The curve is symmetric about the mean: In a normal curve, the mean value of the distribution lies in the centre dividing the distribution curve into two symmetric parts.

Not a characteristic of a normal curve:

3. The value of the mean is always greater than the value of the standard deviation. The mean of the data can be negative as well as positive, but the value of the standard deviation is always positive. The small value of standard deviation implies the presence of more clustered data around the mean. The large value of the standard deviation indicates that the data is more spread out.
