Answer:
B
Step-by-step explanation:
This rectangle appears to have 7 boxes on the bottom, and 3 box for the side.
Since area is base×height
It would be 7×3
Answer:
yes
Step-by-step explanation:
The average weight of the three bags is ...
(55 +51 +48)/3 = 154/3 = 51 1/3 . . . pounds
By removing 3 2/3 pounds of sand from the heaviest bag, adding 1/3 pound to the middle-weight bag, and the remaining 3 1/3 pounds to the lightest bag, Ortega can make all of the bags weigh the same: 51 1/3 pounds.
Answer:
x. = sqrt 6 and x = - sqrt 6
Step-by-step explanation:
x^4 + 2x^2-48=0
(x^2 - 6) (x^2 + 8) = 0
x^2 - 6 = 0
x = + sqrt 6 and x = - sqrt 6
x^2 + 8 = 0
x^2 = sqrt -8 (a negative number doesn’t have a real square root)

SA of a cylinder = (<span>2 * </span>π * r²)<span> + (2 * </span>π *<span> r * h)
SA = </span>(2 * π * 5²) + (2 * π * 5 * 20)
SA = (2 * π * 25) + (2 * π * 5 * 20)
SA = (2 * π * 25) + (2 * π * 5 * 20)
SA = (157) + (628)
SA = 785
The answer is
A. 785 square meters.

SA of a rectangle = 2(wl + hl + hw)
w = 15
l = 4
h = 14
SA = 2(15*4 + 14*4 + 14*15)
SA = 2(60 + 56 + 210)
SA = 2(326)
SA = 652
The answer is
B. 652 square centimeters
