Answer: $5.84

Step-by-step explanation:

Simple interest is calculated using the formula: PRT/100

where P = principal = $425

R = rate = 5.5%

T = time = 3/12 = 1/4 = 0.25

S.I = PRT/100

= (425 × 5.5 × 0.25)/100

= $584.375/1000

= $5.84

Answer:

5 cheeseburgers would be 12.50

Answer: If two cheeseburgers are $5 the then one cheeseburger is 2.50

So 2.50 x 5 is 12.50

So it's 12.50 for 5 cheeseburgers

Answer:

see below

Step-by-step explanation:

This solution is based off of the Triangle Inequality, which states that the sum of the two shortest sides of a triangle must be greater than the longest side of the triangle. The solution looks at the diagram on the bottom where y = DB. Looking at ΔABD, to find the range of values for y, we must consider two possible cases: y is either the shortest side or the longest side. If y is the shortest side then y + 5 > 6 which means y > 1 and if y is the longest side then 6 + 5 > y which means 11 > y. Therefore, the range of values for y is 1 < y < 11.

Next, they made y as small as possible, which would be 1.1 in this case. Looking at ΔDCB, again, to find the range of values for x, we must consider two possible cases: x is either one of the shortest sides or x is the longest side. If x is one of the shorter sides then 1.1 + x > 8 so x > 6.9 and if x is the longest side, 1.1 + 8 > x so 9.1 > x. Therefore, the range of values for x is 6.9 < x < 9.1. The smallest integer value that satisfies this inequality is x = 7.

Answer:

The second option

Step-by-step explanation:

The rate of change needs to stay constant.

The rate of change can be explained by looking at the "rise" (y) over the "run"(x)

The rate of change for the second option is 2.  We know this because...

Rise(2)

----------

Run(1)

Try looking at one of the points, now go up 2 and over 1, you should now be at the second point, do it again but twice, you should now be at the third point. A proportional relationship must also go through the origin (0,0)

Answer:

F(x)=g'(x)h(X)+g(x)h'(x)

F(x)=90x9tan-1-[9*10/(1+x2)}

The derivative of f(x) is f'(x) = 42x⁵ * cos⁻¹(x) - 7x⁶ / (√(1 - x²))

To find the derivative of the function f(x) = 7x⁶ * cos⁻¹(x), we'll use the chain rule and the power rule of differentiation.

The chain rule states that if we have a function of the form f(g(x)), then its derivative is given by f'(g(x)) * g'(x).

Let's break down the function f(x) into two parts:

u(x) = 7x⁶

v(x) = cos⁻¹(x)

Now, we'll find the derivatives of u(x) and v(x):

u'(x) = d/dx (7x⁶) = 6 * 7x⁵ = 42x⁵

To find v'(x), we differentiate cos⁻¹(x) using the inverse trigonometric differentiation formula:

d/dx [cos⁻¹(x)] = -1 / (√(1 - x²))

Now, applying the chain rule to the function f(x) = 7x⁶ * cos⁻¹(x), we get:

f'(x) = u'(x) * v(x) + u(x) * v'(x)

f'(x) = 42x⁵ * cos⁻¹(x) + 7x⁶ * (-1 / (√(1 - x²)))

So, the derivative of f(x) is:

f'(x) = 42x⁵ * cos⁻¹(x) - 7x⁶ / (√(1 - x²))

Question:

One number is 7 times a first number. A third number is 100 more than the first number. If the sum of the three numbers is 505, Find the numbers.

Answer:

The numbers are 45, 315 and 145

Step-by-step explanation:

Represent the three numbers with A, B and C

Required

Find A, B and C

From the first statement;

[tex]B = 7 * A[/tex]

[tex]B = 7A[/tex] --- (i)

From the second;

[tex]C = 100 + A[/tex]  ---- (ii)

From the third;

[tex]A + B + C = 505[/tex]  ---- (iii)

Substitute 7A for B and 100 + A for C in (iii)

[tex]A + 7A + 100 + A = 505[/tex]

Collect like terms

[tex]A + 7A + A = 505 - 100[/tex]

[tex]9A = 405[/tex]

Divide both sides by 9

[tex]A = 45[/tex]

Substitute 45 for A in (i)

[tex]B = 7A[/tex]

[tex]B = 7 * 45[/tex]

[tex]B = 315[/tex]

Substitute 45 for A in (ii)

[tex]C = 100 + A[/tex]

[tex]C = 100 + 45[/tex]

[tex]C = 145[/tex]

Hence, the numbers are 45, 315 and 145

====================================================

Explanation:

There are two methods to approach this type of problem.

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

Method 1

A = junior

B = girl

P(A) = probability of selecting a junior

P(B) = probability of selecting a girl

P(B) = (number of girls)/(number total)

P(B) = (4+7+3+4)/(4+4+5+7+2+3+1+4)

P(B) = 18/30

P(B) = 9/15

P(A and B) = probability of selecting a girl who is a junior

P(A and B) = (number of girl juniors)/(number total)

P(A and B) = 3/30

P(A and B) = 1/10

P(A given B) = P(A and B)/P(B)

P(A given B) = (1/10) divided by (9/15)

P(A given B) = (1/10) times (15/9)

P(A given B) = (1*15)/(10*9)

P(A given B) = 15/90

P(A given B) = 1/6

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

Method 2

This method doesn't involve dividing two fractions which could get messy, which is why I find this the easier route. Since we are given the person is a girl, this means we only need to focus on the "girls" column. There are 3 who are juniors out of 4+7+3+4 = 18 total. The probability of selecting a girl junior is 3/18 = 1/6

Answer:

The amount each took home was 20 unit currency.

Step-by-step explanation:

The given parameters are

The number of apples with each of the seven apple women = 20, 40, 80, 100, 120, and 140

The number of apples each woman has can be written in the following formula obtained online which is a series formula

a·n + (n - 1), (a + b)·n + (n - 2), (a + 2·b)·n + (n - 3), (a + 3·b)·n + (n - 4), (a + 4·b)·n + (n - 5), (a + 5·b)·n + (n - 6), (a + 6·b)·n + (n - 7)

Which gives;

a·n + (n - 1) = 20

(a + b)·n + (n - 2)=40

(a + 2·b)·n + (n - 3) = 60

(a + 3·b)·n + (n - 4) = 80

(a + 4·b)·n + (n - 5) = 100

(a + 5·b)·n + (n - 6) = 120

(a + 6·b)·n + (n - 7) = 140

Solving the above system, we get

n = 7, a = 2, b = 3

Which gives

2×7 + 6 = 20

5×7 + 5=40

8×7 + 4 = 60

11×7 +  3 = 80

14×7 + 2 = 100

17×7 + 1 = 120

20×7 + 0 = 140

Whereby all the women sold the apples for the same sum price, based on market pricing if groups of apples are sold at 1 unit currency for 7, and extras are sold for 3 unit currency per extra 1, we have the amount taking home by each of them given as follows;

2×1 + 6×3 = 20

5×1 + 5×3=20

8×1 + 4×3 = 20

11×1 +  3×3 = 20

14×1 + 2×3 = 20

17×1 + 1×3 = 20

20×1 = 20

Therefore, the amount each took home was 20 unit currency.

Answer:

[tex]\Huge \boxed{{x=15\°}}[/tex]

Step-by-step explanation:

Angles on a straight line add up to 180 degrees.

We can create an equation.

x + 165 = 180

Solve for x.

Subtract 165 from both sides.

x + 165 - 165 = 180 - 165

Simplify the equation.

x = 15

Answer:

15°

Step-by-step explanation:

Angle of a line with a center is 180°

To find x:

x = 180 - 165°

x = 15°

15° is the answer.

So every 5 inches in height, there are 32 marbles. You want to know how many marbles there are per 18 inches in height.

[tex]\frac{32}{5} = \frac{x}{18}[/tex]

To get from 5 to 18, you multiply by 3.6.

Do the same thing to the numerator; 32 × 3.6 = 115.2.

Since 0.2 marbles is no marbles, you round down.

There are 115 marbles in the box.

Answer:

d. g(x) = 5/3 * f(x)

Step-by-step explanation:

A transformation is the movement of a point from its initial position to a new position. Transforming an object involves transforming all the points in the object. Types of transformation are rotation, reflection, dilation and translation.

From the graph When x = 0, y = f(0)  = 30, also when x = 16, y = f(16) = 40

For the graph of g(x), when x = 0, y = g(0) = 50 and when x = 16, y = g(16) = 67

This means that  g(x) = 5/3 * f(x), g(0)  = 5/3 * f(0) =  5/3 * 30 = 50, also g(16)  = 5/3 * f(16) =  5/3 * 40 = 67

Answer:

D.)

Step-by-step explanation:

Answer:

A) 1/2197

B) 1/5525

Step-by-step explanation:

Probability is the likelihood or chance that an event will occur.

Probability = Expected outcome/Total outcome.

Since there are 52 random cards in a deck of card, the total outcome will be 52.

a) Also in a deck of card, there are 4 aces. If we are to select 3 aces with replacement, this means that each time we pick up an ace from the card, it was returned.

Pr(drawing an ace) = 4/52

Pr(drawing 3 aces and replacing it) = 4/52 *4/52*4/52

Pr(drawing 3 aces and replacing it) = 64/140,608

Pr(drawing 3 aces and replacing it) = 1/2197

b) If we pick 3 aces without replacement then each time we pick an ace, the total number cards keeps reducing.

Pr(picking the first ace) = 4/52

Pr(picking the second ace without replacing) = 3/51 (Since we didn't replace the first one, the total ace in the deck of card will reduce to 3 and the total will be 51)

Pr(picking the third ace without replacing) = 2/50 (since we didn't replace the first two aces, the total ace in the deck of card will reduce to 2 and the total will be 50)

Pr(drawing 3 aces without replacement) =  4/52*3/51*2/50

Pr(drawing 3 aces without replacement) =  24/132,600

Pr(drawing 3 aces without replacement) = 1/5525

The probability of selecting a multiple of 2 or a multiple of 3 from the integers 1-20 is 13/20.

Probability is the likeliness of happening an event among all the events possible to happen. The formula of calculating probability is number/ events/total numbers/ total events. The value of probability lies between 0 and 1.

We have to find out the probability of selecting a multiple of 2 or a multiple of 3 from the integers 1-20.

Multiples of 2 from 1 to 20=2,4,6,8,10,12,14,16,18,20= 10 numbers

Multiples of 3 from 1 to 20=3,6,9,12,15,18=6 numbers

Common multiples 6,12,18=3 numbers

Total numbers from 1 to 20=20

Probability=(10+6-3)/20

[ we have deducted 3 because we have to just take a number once while calculating probability]

=13/20

Hence the probability of selecting a multiple of 2 or a multiple of 3 from the integers 1-20 is 13/20.
