Answer:

Distributive property

Step-by-step explanation:

Distributive property has more than one operations used.

Ex; 6(2x + 3) = 42

12x + 18 = 42

- 18. - 18

12x = 24

12x/12 = 24/12

x = 2

You can see that in the expression above, we used multiplication, addition, subtraction, and division. Since we use more than one operation, distributive property would be your answer. Hope this helps, thank you :) !! (Also sorry for answering late.)

What is the radius of a hemisphere with a volume of 757 cm", to the nearest tenth of

Nataliya [291]

Answer:

r = 7.1 cm

Step-by-step explanation:

Given the following data;

Volume of hemisphere = 757 cm³

To find the radius of the hemisphere;

Mathematically, the volume of a hemisphere is given by the formula;

Volume of hemisphere = ⅔πr³

Where, r is the radius of the hemisphere.

π = 22/7

Substituting into the formula, we have;

757 = ⅔πr³

Cross-multiplying, we have;

757 * 3 = 2πr³

2271 = 2*22/7*r³

2271 = 44/7*r³

Cross-multiplying, we have;

2271 * 7 = 44r³

15897 = 44r³

r³ = 15897/44

r³ = 361.30

Taking the cube root of both sides, we have;

r = 7.1223

To the nearest tenth of a centimeter;

r = 7.1 cm

Elizabeth wants to ride her bicycle 28.6 miles this week. She has already ridden 19 miles. If she rides for 3 more days, write a

8090 [49]

Answer: The average number of miles she would have to ride each day to meet her goal = 3.2 miles.

Step-by-step explanation:

Given: Elizabeth wants to ride her bicycle 28.6 miles this week.

She already ridden 19 miles.

Number of days she will ride more =3

Let m = average number of miles ridden in a day.

Then,

Total distance = initial distance + (m) (Number of days)

i.e. 28.6 = 19+3m (Required equation)

Subtract 19 from both sides , we get

$9.6=3m\\\\\Rightarrow\ m=\dfrac{9.6}{3}\\\\\Rightarrow\ m=3.2\ miles$

Hence, the average number of miles she would have to ride each day to meet her goal = 3.2 miles.
