Answer:

30 Oranges

Step-by-step explanation:

The ratio of apples to oranges is 4:3.  For every 4 apples there are 3 organges.  We can write that as 4A/3O, where A and O are Apples and Oranges.  This can be rewritten as percentages of each fruit.  A bag of 7 would have 4 Apples (4/7) or 0.5715 [57.15%] and 3 Oranges (3/7) or 0.4285 [42.85%].

A bag of 70(A and O) can be determined to have:

Apples:  70*(0.5715) =  40 Apples, and

Oranges:  70*(0.4285) = 30 Oranges

Therefore , the solution of the given problem of equation comes out to be k1 = - 0.67 and k2 = -0.1.

A mathematical equation is a formula that joins two statements and uses the equal symbol (=) to indicate equality. A scientific statement that verifies the equality of two formalisms is known as an equation in algebra. For instance, the pieces ptdc + 6 and 12 are separated by an equal sign in the solution obd + 6 = 12. The relationship between the two phrases on either flank of a letter is described by a mathematical formula. Often, there is only one variable, which also serves as the symbol. for instance, 4x – 4 = 0.

Here,

If y varies in this case simply also as square of x

k is the proportionality constant, and

y = kx² in mathematics.

Considering y = -54 and x = 9,

y = kx²

k = y/ x²

k = -54/ 9²

k = -54/81

k1 = - 0.67

Moreover, if y=-11/3 and x=6,

k = y/x²

k = -3.667/ (6)²

k = -3.667/36

k2 = -0.1

Therefore , the solution of the given problem of equation comes out to be k1 = - 0.67 and k2 = -0.1.

Then the area of the parallelogram is calculated as,

=> A = 24 x 10

Then the resulting value is

=> A = 240.

Here we have given that the total given area of the floor is 1080 sq.cm.

Then the required number of tiles is calculated by dividing the terms, then we get,

(a) To determine if it is possible to prepare 21 goodie bags exactly, we need to check if 450 notebooks and 315 fridge stickers can be divided equally into 21 goodie bags without any leftovers.

To do this, we can use the greatest common divisor (GCD) of 450 and 315, which is 15. If the GCD is not 1, it means that the two numbers cannot be divided exactly, so it is not possible to prepare exactly 21 goodie bags with 450 notebooks and 315 fridge stickers.

(b) To find the largest number of goodie bags that can be prepared, we can use the least common multiple (LCM) of 450 and 315. The LCM is 990, which means that 990 notebooks and 990 fridge stickers can be divided into the same number of goodie bags without any leftovers. Therefore, the largest number of goodie bags that can be prepared is 990/450 = 990/315 = 2.

(c) Using the answer from (b), we can calculate how many notebooks and fridge stickers will be in a goodie bag. If we divide 990 by 2, we get 495. Therefore, there will be 495 notebooks and 495 fridge stickers in each goodie bag.

Answer:

30%

Step-by-step explanation:

The level of decay is determined by the number raised to the power.

y = 0.4(0.7)^t

If you had 1^t, there would be no decay or growth since 1^t is always 1.

Instead, you have 0.7^t

As t increases, 07^t decreases. That is where the decay comes from.

Now look at 0.7

In the general decay equation, you have

y = a(1 - r)^t

r is the rate of decay.

Here we have 0.7

0.7 = 1 - 0.3

the rate of decay is 0.3 or 30%

Answer:

The equation y = 0.4(0.7)^t represents an exponential decay of 30%. The decay rate is determined by the value in the parentheses, which in this case is 0.7. To calculate the decay rate, you can subtract this value from 1, giving you 1 - 0.7 = 0.3, or 30%.

The events are not mutually exclusive because P(A or B) ≠ P(A) + P(B). The probability of either event happening is not equal to the sum of each event happening.

Mutually exclusive events are events that cannot happen at the same time. For example, when you are tossing a coin, you cannot get head and tail at the same time. They are mutually exclusive, also called disjoint events, where P(A and B) = 0.

In mutually exclusive events, it also states that the probability of either event happening is the sum of probabilities of each event happening. It means that P(A or B) = P(A) + P(B).

Your question is incomplete and here is the complete question.

The probability for event A is 0.3, the probability for event B is 0.6, and the probability of events A or B is 0.8. Why are the events not mutually exclusive?

From the information, we have:

Let's check if the events are mutually exclusive!

P(A or B) = P(A) + P(B)

P(A or B) = 0.3 + 0.6

P(A or B) = 0.9

0.8 ≠ 0.9

P(A or B) ≠ P(A) + P(B)

The probability of A or B is not equal to the sum of the individual probabilities. It proves that A and B are not mutually exclusive.

You use Alternate interior angles to get angle 2, then vertical angles to find angle 1

Red is alternate interior angles

Yellow is vertical angles

Step-by-step explanation:

when a line intersects 2 or more parallel lines, it must have the same intersection angles with each of the parallel lines. otherwise the lines are not parallel after all, because parallel lines imitate each other's properties and behaviors exactly except for the actual location.

so,

angle 1 = 135°

the intersection angles between 2 lines must be the same in each side of each line, they are just left-right mirrored.

Answer:

The total amount that will be paid for the coat would be; $79.95  to the nearest cent.

Step-by-step explanation:

What is income tax?

Income tax is a tax applied on individuals or entities concerning income or profit earned by them.

Given that Jack wants to buy a coat that costs $74.95. The sales tax rate in his city is 6 and 1/2 percent.

Thus, the total cost for the coat can be calculated as;

The amount that will be paid for the coat will be;

= Amount of shirt + Tax

= $74.95 + (6.5% × $74.95)

= $74.95 + (6.5/100 × $74.95)

= $74.95 + $4.80

= $79.95

The total amount that will be paid for the coat would be; $79.95 to the nearest cent.

For more information, refer to this link: brainly.com/question/28973590

The total cost for the coat is $79.55

The total cost of the coat is the sum of the cost of the coat and the sales tax. To find the sales tax, Jack needs to multiply the cost of the coat by the sales tax rate as a decimal.

$74.95 x 0.0612 = $4.60452

To find the total cost, he would add this amount to the cost of the coat:

$74.95 + $4.60452 = $79.55452

Rounding to the nearest cent , the total cost of the coat is $79.55. It means Jack has to pay $79.55 including the sales tax, which is $4.60452 on the original price of $74.95 for the coat.

Calculate the rise over the run ratio of a line going through the points (-7,3) and (4, 2). With this in mind, the rise over run ratio of the line joining the two points is -1/11. Decide on the coordinates of two spots along the line.

Find the location of these two points' respective y-coordinate differences (rise). The difference between these two places' x-coordinates should be known (run). In order to calculate the difference in y-coordinates (rise/run or slope), divide it by the difference in x-coordinates.

Answer:

To find the principal amount, you can use the formula for continuously compounded interest:

A = Pe^(rt)

where A is the final account balance, P is the initial principal (or starting) amount, r is the interest rate, and t is the time (in years) for which the interest is being calculated.

Substituting in the given values:

1,433,785.18 = P * e^(0.054 * 12)

To find P, we can divide both sides by e^(0.054 * 12)

P = 1,433,785.18 / e^(0.054 * 12)

The interest rate for the second and third years is 0.9%.

The interest rate for the second and third years is 0.9%.

We can use the formula for compound interest to find the value of x:

A = P(1 + r/n)^(nt)

Where:

A is the final amount (209754 yen)

P is the initial amount (200000 yen)

r is the interest rate (x% for the second and third years)

n is the number of times the interest is compounded per year (let's assume it is compounded annually)

t is the number of years the money is invested (3 years)

We know that the interest rate for the first year is 1.8%.

So we can calculate the final amount after the first year using:

A = P(1 + 1.8/100)^1

A = P(1.018)

A = 200000*(1.018) = 203600

So, the total amount after the first year is 203600 yen.

Now let's find the remaining interest rate for the second and third years:

A = P(1 + r/100)^(2)

203600 = 200000(1 + r/100)^2

We can now solve for the value of x by isolating r/100

r/100 = (203600/200000)^(1/2) - 1

x = (r/100)*100

x = (203600/200000)^(1/2) - 1*100

x = 0.9%

x is 0.9%

Hence, the interest rate for the second and third years is 0.9%.
