1 answer:

7 0

To solve this completion exercise, you must keep on mind the following information:

- The formula for calculate the area of a sphere, is the following:

Vsphere=4πr³/3

Where Vsphere is the volume of the sphere and "r" is the radius of the sphere.

- Therefore, if you multiply the radius by 3, or triple the radius, the surface area increase by a factor of 9 (3^2=9).

The answer is: Tripling the radius of a sphere increases the surface area by a factor of 9.

The school cafeteria sells two kinds of wraps: vegetarian and chicken. The vegetarian wrap cost $1 and the chicken wrap cost$1.8

vfiekz [6]

Let us assume the number of vegetarian wraps made = x
Let us assume the number of chicken wraps made = y
Then
x + y = 70
x = 70 - y
And
x + 1.80y = 98.80
Putting the value of x from the first equation in the second equation, we get
x + 1.80y = 98.80
70 - y + 1.80y = 98.80
0.80y = 28.80
y = 36
Putting the value of y in the first equation, we get
x + y = 70
x + 36 = 70
x = 34
From the above deduction, we can conclude that the number of vegetarian warps sold was 34. I hope the answer has come to your desired help.

dedylja [7]

If Marita has one dime, she has 0.10 = 1/10 dollars. If she has "x" times that many dimes, she has 0.10x = x/10 dollars (in dimes).

The only answer choice containing this term is ...
( A ) x/10 + 0.75 + 10y
