Answer:

Area = 64 + 16\pi

Step-by-step explanation:

Given

See attachment for the heart created

Required

The area of the heart

The area of the heart is the sum of the area of the square and the areas of the two semicircles.

From the attachment, we have:

s = 8in --- length of the square

d = 8in --- diameter of each semicircle

Calculate radius

r = 0.5 * d

r = 0.5 * 8 = 4in

The area of the square is:

Area = Length^2

A_1 = 8^2

A_1 = 64in^2

The area of the two semicircles is:

A_2 =2 * \frac{\pi r^2}{2} i.e. 2 multiplied by the area of 1

A_2 = \pi r^2

A_2 = \pi *4^2

A_2 = \pi *16

A_2 = 16\pi

So, the area of the heart is:

Area = A_1 + A_2

Area = 64 + 16\pi

What is the mean for this set of data?
oee [108]
The mean is 14

add all the numbers up and divide the sum by 6 because that’s how many numbers you’re adding together.

12+10+14+18+14+16
= 84

84/6 = 14

Two mechanics worked on a car. The first mechanic charged $95  per hour, and the second mechanic charged $60  per hour. The mech
Yanka [14]

Answer:

<em>Mechanic A worked for 5 hours</em> and <em>Mechanic B worked for 15 hours</em>

I hope my answer and explanation helped!

<u>okay to get started you need to make a system of equations:</u>

x= number of hours worked by mechanic A

y= number of hours worked by mechanic B

x + y= 20

95x + 60y= 1375

<u>substitute in an equation:</u>

x + y= 20

y= 20- x

95x + 60(20-x)=1375

<u>Solve for x</u>

95x + 1200 - 60x=1375

35x =175

x= 5

<u>plug in x to solve for y</u>

x + y= 20

5 + y= 20

y=15

<u>Check work</u>

then you're done :D
