3) What is the SURFACE AREA of the solid with the given measurements? Square Pyramid base edge 4 cm, slant height 11 cm​
atroni [7]

Answer:

Step-by-step explanation:

height h = 11 cm

slant height s = 11.180339887499 cm

side length a = 4 cm

lateral edge length e = 11.357816691601 cm

1/2 side length r = 2 cm

volume V = 58.666666666667 cm3

lateral surface area L = 89.442719099992 cm2

base surface area B = 16 cm2

total surface area A = 105.44271909999 cm2

Siri is grocery shopping. She is buying macaroni. One box is 6 inches long, 1 inch wide and 9
sashaice [31]

Answer:

The second box  

Step-by-step explanation:

The volume of a pyramid can be given by the formula:  V=31​Ah. Where.  A:  Area of the V=(1/3)(B)(h)

multiply both sides by 3

3V=Bh

divide both sides by B

3V/B=h

Therefore, If it is wider it has more space to carry more items such as macaroni.

I hope this helps! (:

If Nathan does 9 minutes of push ups for 3 days, that's 9 divided by 3, which is 3. (9/3=3)  So nathan does 3 minutes of push ups each day, so just multiply each day by 3 to find the correlation between the two.

The Table should look like this: 

# of days      # of Minutes
1                     3
2                     6

The carnival charges $5 admission and $0.50 for each ride. Alex's dad gave him $15 to spend. How many rides can he go on at most
Oxana [17]

Let us suppose number of rides is x.One ride costs $0.50.

Cost of x rides is 0.50x. The carnival charges is $5. Alex has $15 to spend .

Number of rides at most Alex can have can be given by the inequality:

0.50x+5≤ 15

To solve for x we subtract 5 both sides

0.50x≤ 15-5

0.50x≤ 10

Dividing both sides by 0.50 we have :

x≤ 20

Number of rides at most Alex can have is 20.
