Answer:

21m

Step-by-step explanation:

So for the rectangle, do 5*6, and you will get the area of the whole backyard. Then to get the area of the grass, you do 3*3 to get 9.

Finally, to get the cement, you subtract the area of the grass from the area of the whole backyard so 30-9 to get 21.

5*6=30

3*3=9

30-9+21

Each year the residents of a country purchase 60 billion ice cream cones. If there are 252 million people in the​ country, how many ice cream cones are purchased per person in one​ year?

Answer: Number of ice cream cones purchased by the residents = 60 billion

60 billion = 60,000,000,000

Number of residents in the country = 252 Million

252 Million = 252,000,000      

Therefore, the number of ice cream cones purchased per person in one​ year is:

\frac{Total-Ice-cream-cones-purchased}{Total-number-of-residents}

\frac{60,000,000,000}{252,000,000}

238.10 \approx 238 ice cream cones

The sum of the angle measures of the polygon is 540°. Write and solve an equation to find the value of 2.
kifflom [539]

Answer:

x = 29°

The angles are  137° , 116° , 96° , 44° and 147°

Step-by-step explanation:

The sum of the angles of the polygon is given as 540°. The angles are given as 5x – 8°,  4x° , 96° , 44°, 5x + 2. Therefore, the value of x can be found as follows

5x – 8° + 4x°  + 96° + 44° + 5x + 2° = 540°

collect like terms

5x + 4x + 5x - 8 + 96 + 44 + 2 = 540°

14x + 134 = 540°

14x = 540 - 134

14x = 406

divide both sides by 14

x = 406/14

x = 29°

Therefore, the angles are as follows

29 × 5 - 8 = 137°

29 × 4 = 116°

96°

44°

5 × 29 + 2 = 147°
