Pump A = 45 mins
Pump B = 35 mins
Pump A and B = (45 x 35) / ( 45 + 35) = 19.69 mins (nearest hundredth)

Answer: 19.69 mins
Answer:
d. 175 square inches
Step-by-step explanation:
If we assume the base is square and all triangular faces are congruent, then the lateral area of the figure is that of four triangles. Each triangle has an area that is half the product of its base and height:
A = (1/2)bh = (1/2)(7 in)(9 in) = 31.5 in^2
The area of the square base is the product of its length and width, both of which are 7 in.
A = lw = (7 in)(7 in) = 49 in^2
So, the total surface area is that of the base plus the four sides:
surface area = (49 in^2) + 4(31.5 in^2) = 175 in^2 . . . . . matches choice D
First you multiple 8x times 7x and get 56x and since 3y doesn't have another y so u Leave tht as 3y then you multiply 3z times 6z and get 18z then you multiply 4 times 6 and get 24 (56x^3y)(18z^24)
Hi there!
A recipe for cake needs 3/4 of a cup of milk.
We are making 1/2 of the recipe, which means we also need half of the milk needed for the total recipe. Therefore, we can multiply 1/2 (half of the recipe) by 3/4 (the total amount of cups of milk needed for the total recipe).
Hence, we need
3/8 cups of milk
