Show your work.
A. 38
B. 60
C. 239
D. 23

Answers

Answer 1

Answer:

A, 38cm

Step-by-step explanation:

since u have to take 15cm (the length) then multiply by 2 to take both the sides of the rectangle

then you have to take the width 2 times to take the perimeter and add it up. so 15x2 and 4x2 added is 38. there!

In Richmond, Chloe ordered $40 worth of sushi. She knew that when the bill came, she would need to pay Richmond sales tax for 5% and would want to leave a 20% tip on the original $40. including tax and tip, How much did Chloe meal cost?

Answers

Answer:

$50

Step-by-step explanation:

Given data

Cost of sushi= $40

Tax= 5%

Tip= 20%

Let us find the amount of the tax and the tip

Tax

=5/100*40

=0.05*40

=$2

Tip

=20/100*40

=0.2*40

=$8

Hence the total amount paid is

=40+2+8

=$50

Answer:

$50

Step-by-step explanation:

To avoid confusion, we can solve for the sales tax and the tip separately.

Tip

Original Bill x 20%Original Bill x 1/5$40 x 1/5$8

Tax

Original Bill x 5%Original Bill x 1/20$40 x 1/20$2

Total

Original Bill + Tip + Tax$40 + $8 + $2$50

If $500 is invested at 8% annual interest, how much will be in the account after 3 years if it's compounded quarterly?

Answers

Answer:

FV= $634.12

Step-by-step explanation:

Giving the following formula:

Initial investment (PV)= $500

Number of periods (n)= 3*4= 12 quarters

Interest rate (i)= 0.08/4= 0.02

To calculate the future value, we need to use the following formula:

FV= PV* (1 + i)^n

FV= 500*(1.02^12)

FV= $634.12

What is the volume of a ball if its diameter is 6 inches? Leave your answer in terms of π.
A) V = 12 π cubic inches

B) V = 36 π cubic inches

C) V = 288 π cubic inches

D) V = 27.75 π cubic inches

Answers

Answer:

B

Step-by-step explanation:

I am assuming that this ball is a perfect sphere.

The volume of a sphere is [tex]\frac{4}{3} *\pi *r^3[/tex]

We have the diameter, and in order to find the radius, we just have to divide by 2. 6/2=3. Now, we have to plug in the 3 to the equation.

[tex]\frac{4}{3} *\pi *3^3[/tex]

3 cubed is 27, so now we have [tex]\frac{4}{3} *\pi *27[/tex]

27*4/3*pi=36pi

The volume of a ball if it’s diameter is 6 inches. It’s is 36 the answer is B

The area sector of a circle with radius 7 is 9 π/. What is the radian measure θ, the central angle of the sector? Express your answer in exact form.

Answers

Answer:

Radian angle = 1.154

Central angle = 66.123°

Step-by-step explanation:

Area of Sector, A

A = 1/2 * r² * θ ; θ measured in radian

A = 9 π

r = 7

9 π = 1/2 * 7² * θ

9 π = 24.5θ

θ = 9 π / 24.5

θ = 1.154 radian

1 radian = 57.296°

1.154 radian = (57.296 * 1.154)

1.154 radian = 66.123°

The sum of three consecutive odd integers is 189. What
are the integers?

Answers

Answer:

61, 63, 65

Step-by-step explanation:

n + n+2 + n+4 = 189

3n = 183

n = 61

Answer:

The three consecutive odd integers are 61, 63, and 65

Step-by-step explanation:

Let the three consecutive odd integers be:

n + 1, n + 3 and n + 5

Therefore:

n + 1 + n + 3 + n + 5 = 189

3n + 9 = 189

3n = 180

n = 60

n + 1 = 61

n + 3 = 63

n + 5 = 65

Option 3

Step-by-step explanation:

By applying Pythagoras theorem in the given triangle,

(Hypotenuse)² = (Leg 1)² + (Leg 2)²

x² = (9.5)² + (10.5)²

x² = 200.5

x = √(200.5)

x = 14.16

x ≈ 14.2

Therefore, measure of the unknown side is 14.2 in.
