Answers

Answer:

99.75 square feet.

Step-by-step explanation:

First we would find the area of both shapes.

rear = 12.5

distance from back and front is 9.5.

to find the area of the rectangle, you'll need to do 12.5 x 9.5

= 118.75.

Then you'd find the area of the triangles;

BH/2.

4 x 9.5. = 38. divided by 2,

= 19.

than you subtract them,

118.75 - 19 = 99.75.

10% of the world’s population is left-handed. If there are 7,400,000,000 people on the planet, how many are left-handed and how many are right handed?

Answers

Answer:

740,000,000 people are left handed and around 666,000,000 people are right handed.

Step-by-step explanation:

I think this is the correct answer. Hope I helped!

740,000,000 left handed people
6,660,000,000 right handed people
Steps:
10% is equal to 0.1
7,400,000,000 multiplied by 0.1
Equals 740,000,000 left handed
Total amount of people subtract left handed people equal right handed people
7,400,000,000 - 740,000,000 = 6,660,000,000 right handed people

Miranda has been offered two jobs. The pay at job A would be $750 per month plus 15% of the value of the merchandise she sells. Job B offers $675 per month plus 20% of the value of the merchandise she sells. What value of merchandise must she sell in order to make more money at job B than job A? Which of the following best represents this situation?



A. 750 + 0.15x = 675 + 0.20x

B. 750 + 0.20x = 675 + 0.15x

C. 750 + 0.15x > 675 + 0.20x

D. 750 + 0.15x < 675 + 0.20x

Answers

it’s C i think cause it’s saying it offers $675 more so > is the more sign

Answer:

x - would be the total value of merchandise sold

y - would be her take home pay would be

Job A: y = 0.15x + 750

Job B: y = 0.20x + 675

We want to know when job B's pay will be larger than job A's pay. So set the expression for job B larger than job A, solve for x

0.20x + 675 > 0.15x + 750

0.20x - 0.15x > 750 - 675

0.05x > 75

x > 75/0.05

x > 1500
