Answer:
H = 5
Step-by-step explanation:
rectangular prism:
V = L x W x H
400 cm3 = 16 x 5 x H
400 cm3 = 80 x H
400/80 = 5
h = 5 cm
95% sure this is correct! :)
Answer:
64π square feet (the formula for the area is r^2π so you have to multiply 8 with itself and you get 64. 64×π is 64π)
Answer:
The perimeter of the rectangle is 54 meters.
Step-by-step explanation:
In order to find the perimeter of the rectangle, which is the sum of all the sides, we need to know not only the length, but also the width. The formula for area of a rectangle is A = length x width. Setting up an equation to find width 'w', we get: 162 = 18 x w. Using inverse operations, we divide both sides of the equation by 18 to get w = 9. Since we now know that w = 9 and l = 18, we can find the perimeter using the following equation: P = 2w + 2l or P= 2(9) + 2(18) or P=54 meters.
Answer:
the answer d , the second answer is b, the third answer is b,
Step-by-step explanation:
Answer:
x: 12 9 6 3
y: 11 8 5 2
Step-by-step explanation:
Every box is the previous number minus 3. For x, they say to start with 15 and subtract 3, so the first box is 15-3. The second box is the previous box, 12, minus 3 and so on. Y is done the same way. Hope this is helpful :)
