8 out of 12 people were happy.

8/12 reduces to 2/3 of the people were happy.

Multiply the total people surveyed by 2/3:

126 x 2/3 = (126 x 2) /3 = 252/3 = 84

84 people were happy.

Find the value of x given the diagram below
Pie

The value of x is 44°.

Step-by-step explanation:

Step 1:

The sum of the angles in a triangle is equal to 180°.

The sum of the angles along a straight line is 180°.

The two given angles of the triangle are 14° and 30°.

Assume the third angle is a.

The sum of 14°, 30° and a is 180°.

14+30+a=180.

a = 180-44 = 136.

So the third angle of the triangle is 136°.

Step 2:

The sum of the angles along a straight line is 180°.

The sum of the angle of the triangle, 136° and x is 180°.

136+x=180.

x = 180- 136 = 44.

So x measures 44°.

Andre wants to save $40 to buy a gift for his dad. Andre’s neighbor will pay him weekly to mow the lawn, but Andre always gives
kirill115 [55]

Answer:

<u>Andre’s neighbor pays him $ 10 each week to mow the lawn </u>

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Cost of Andre's dad gift = $ 40

Weekly donation to the food bank = $ 2

Number of weeks to save $ 40 = 5

2. How much does Andre’s neighbor pay him each week to mow the lawn?

Let's calculate this amount, this way:

Weekly payment = [Cost of the gift + (Weekly donation * Number of weeks to save)]/Number of weeks

Replacing with the real values we know:

Weekly payment = [40 + (2 * 5)]/5

Weekly payment = 50/5 = 10

<u>Andre’s neighbor pays him $ 10 each week to mow the lawn </u>
