Answer:

Answer:

a) 4 1/10 slices eaten

b) cannot be solved because we don't know how many slices in each pizza

Step-by-step explanation:

Christine is fertilizing her garden. the garden is in the shape of a rectangle. its length is 12 ft and it's width is 10 feet. suppose each bag of fertilizer covers 30 square feet. how many bags will she need to cover the garden?

Answers

Answer:

4

Step-by-step explanation:

First we need to find the total area of the garden so we can see how many bags she will need. The area of a rectangle is its length multiplied by its width, so the area of her garden is 12 (the length) x 10 (the width). 12 x 10 = 120 square feet. If each bag covers 30 square feet, then she will need 120/30 = 4.

4 bags of fertilizer to cover the 120 square feet of the garden area.

Write the expression multiply 0.035 times of a power of 10 so that the product is greater than one by less than 100

Answers

Answer:

0.035* 10^(3)

0.035* 10^(2)

Step-by-step explanation:

Given the number: 0.035 which has three decimal place

  • Case 1:  if we multiply  by 10

=> we have: 0.035*10 = 0.35

Hence, the product 0.35 which is smaller than 1 (we do not accept)

  • Case 2:  if we multiply  by 1000

=> we have: 0.035*1000 = 35

Hence, the product 35 which is greater than 1 and less than 100

  • Case 3:  if we multiply  by 100

=> we have: 0.035*100= 3.5

Hence, the product 3.5 which is greater than 1 and less than 100

  • Case 4:  if we multiply  by 10000

=> we have: 0.035*10000= 350

Hence, the product 350 which is greater than 100 (we do not accept)

Therefore, we have two expression:

0.035* 10^(3)

0.035* 10^(2)

Suppose a parabola has vertex (-3, 7) and also passes through the point (-2, 11). Write the equation of the parabola in vertex form.​

Answers

Answer:

f(x)=4(x-(-3))+7

Step-by-step explanation:

vertex form= f(x)=a(x-h)^2 +k

vertex= (h,k)

x=-2

f(x)=11

plug in all the variables

11=a(-2-(-3))^2 +7

simplify the right side

11=a(1)^2+7

11=a+7

subtract 7

4=a

equation= f(x)=4(x-(-3))+7
