Answer:

56.25π cm^2

Step-by-step explanation:

circumference = 15π

diameter*π = circumference

diameter = 15π/π

radius*2 = diameter

radius*2 = 15

radius = 7.5

area = π*radius^2

area = π*7.5^2

area = 56.25π

Answer:

A = 56.25π cm²

Step-by-step explanation:

the area (A) of a circle is calculated as

A = πr² ( r is the radius )

to find r use the circumference formula

C = 2πr

given C = 15π , then

2πr = 15π ( divide both sides by 2π )

r = 7.5 cm

then

A = π × 7.5² = 56.25π cm²

Answer:

9)  A.  ∠1 and ∠3

10)  B.  Angle 2

11)  B.  110°

12)  B.  70°

Step-by-step explanation:

Vertical angles:  a pair of opposite angles formed by two lines intersecting.  Vertical angles are congruent.

The vertical angles in the given diagram are ∠1 and ∠3  AND  ∠2 and ∠4

These pairs of angles are equal, so: ∠1 =∠3  AND ∠2 =∠4

Therefore:

If ∠1 = 110°  then  ∠3 = 110°

If ∠2 = 70°  then  ∠4 = 70°

Answer:

[tex]113\° = \angle A[/tex]

Step-by-step explanation:

Given:

If ∠A is equivalent to ∠B, then...

[tex]\implies 7x - 20 = 6x - 1[/tex]

Add 1 both sides:

[tex]\implies 7x - 20 + 1= 6x - 1 + 1[/tex]

Simplify both sides:

[tex]\implies 7x - 19= 6x[/tex]

Subtract 7x both sides:

[tex]\implies 7x- 7x - 19= 6x - 7x[/tex]

Simplify both sides:

[tex]\implies -19= -x[/tex]

Divide both sides by -1:

[tex]\implies \dfrac{-19}{-1} = \dfrac{-x}{-1}[/tex]

Simplify both sides:

[tex]\implies 19= x[/tex]

Substitute the value of x into "7x - 20" to determine ∠A:

[tex]\implies 7x - 20 = \angle A[/tex]

[tex]\implies 7(19) - 20 = \angle A[/tex]

Simplify the expression:

[tex]\implies 133 - 20 = \angle A[/tex]

[tex]\implies 113\° = \angle A[/tex]

Answer:

∠ A = 133

Step-by-step explanation:

Putting both angels together

Since,

m ∠ A = (7x-20)

m ∠ B = (6x-1)

Thus,

(7x-20) = (6x-1)

Solving for x:

7x  - 20 = 6x -1

  +20           +20

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

7x =  6x + 19

-6x    -6x  

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

1x = 19  

x = 19

7(19) -20 =  113

6(19) - 1 = 113  

Hence measure of m ∠ A = 113

An equation is formed when two equal expressions. The equation has only one solution which is equal to 16.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

The solution to the equation can be done in the following manner,

[tex]\dfrac{3}{2g+8} = \dfrac{g+2}{g^2-16}\\\\3(g^2-16)= (g+2)(2g+8)\\\\3g^2 - 48 = 2g^2+8g+4g+16\\\\3g^2-48=2g^2+12g+16\\\\3g^2-2g^2-12g-48-16=0\\\\g^2-12g-64=0\\\\g^2-16g+4g-64=0\\\\g(g-16) + 4 (g-16)=0\\\\(g-16)(g+4)=0[/tex]

Thus, we will get the value of g as -4 and 16. But if we substitute the value of g as -4, the equation will have 0 as the denominator on both sides.

Hence, the equation has only one solution which is equal to 16.

Answer:

$20.00

Step-by-step explanation:

t represents the total amount

0.25t = 5.00

Can you solve for t and answer?

Or logically

Peter's $5.00 is 1/4 (25%) of the total.

Therefore 4/4 is $20.00

Answer:

$40.00

Step-by-step explanation:

Peter's $12.00 is 30% of the total money all the brothers had.

$12.00 divided by 30% (.30) = $40.00

To double check, multiply $40.00 total money X Peter's share of 30%

$40.00 X 30% (.3) = $12,00

Answer: h=11.9

Step-by-step explanation:

We know that the hypotenuse is 13 and we have the adjacent side of the angle 24. This means we can use cosine to solve.

[tex]cos(x)=\frac{adjacent}{hypotenuse} \\cos(24)=\frac{h}{13}[/tex]

Multiply both sides by 13 to isolate h

[tex]cos(24)=\frac{h}{13} \\(13)cos(24)=\frac{h}{13}(13)\\13cos(24)=h[/tex]

h=11.9

Answer:

Find by using 1st derivative test (tests slope) or 2nd derivative test (test concavity). Maximum is 18.75.

Step-by-step explanation:

The maximum of the equation is found when the slope is 0; therefore, take the derivative of the equation, find the critical point and find whether the function is increasing or decreasing around the critical point. To do this use test values within the interval of (-∞, 4.5) and (4.5, ∞). You then find that (-∞, 4.5) is increasing meaning there is a maximum. Plug in 4.5 into f(x) to find the y value.

Second method is using the 2nd derivative test. Find the second derivative and use the same method of testing intervals but instead plugging in test values to the 2nd derivative. You then find that f''(x) is < 0 meaning the function is concave down, thus having a maximum. Plug in 4.5 to find the y value.

The monthly payment of a loan for $3,000 at 7.5% interest compounded monthly for 36 months is $93.32.

loan amount P = $3000

Rate of interest = 7.5% per annum

So, monthly rate of interest r= 7.5/12 %

Tenure n = 36 months

The formula to calculate monthly payments is given

[tex]EMI=\frac{Pr}{1-(r+1)^{-n} }[/tex]...........(1)

Where P =loan amount

r = monthly rate of interest

n=tenure

So by substituting the given values in (1) the monthly payment = $93.32

Hence, the monthly payment of a loan for $3,000 at 7.5% interest compounded monthly for 36 months is $93.32.

Answer:

2762 in²

Step-by-step explanation:

The total surface area of a figure is the sum of the areas of its faces.

Area of rectangle= length ×breadth

Assuming that this is a closed box, the total surface area is the total area of its 6 rectangular faces.

Two rectangles have dimensions of 7 in. ×19 in., another two rectangles have dimensions of 48 in. ×7 in., and the last two rectangles have dimensions of 48 in. ×19 in.

Surface area of the figure

= 2(7)(19) +2(48)(7) +2(48)(19)

= 266 +672 +1824
