-11 2/3 * (-4 1/5)
= -35/3 * (-21/5)
= $\frac{-35 * (-21)}{3 * 5}$
= 735/15
= 49.

70 POINTS PLEASE HELP! A dump truck pours sand into a container in the shape of a rectangular prism with a square base of length

galina1969 [7]

Answer:

Step-by-step explanation:

The volume of a rectangular prism is:

$V=\ell wh$

Since the prism has a square base, each side length being 2, this means that both the length and width of our prism is 2. Therefore:

$V=(2)(2)h=4h$

So, we can write:

$V=4h$

The height h increases at a rate of about 8 inches or 8/12 = 2/3 feet per minute.

So, after t minutes, the height will be 2/3(t) feet. Thus, we can substitute:

$\displaystyle V=4\Big(\frac{2}{3}\Big)t=\frac{8}{3}t$

We want to find after how long it will be until the volume is 64 cubic feet. So, V = 64:

$\displaystyle 64 = \frac{8}{3} t$

Solve for t:

$\displaystyle t=\frac{3}{8}(64)=3(8)=24\text{ minutes}$

The correct answer is A.

Khairul is x years old .Khairul`s uncle is 4 times as old as khairul will be in 5 years .Find the present age of Kharuls`s uncle

rodikova [14]

Answer:

4x + 15

Step-by-step explanation:

Let the age of Khairul's uncle y.

From the question given above, the following were obtained:

Khairul's age = x years

In 5 years time:

Khairul's age = x + 5

Khairul's uncle age = y + 5

But from the question given above,

Khairul`s uncle will be 4 times as old as what khairul will be in 5 years. This can be written as follow:

y + 5 = 4(x + 5)

Clear bracket

y + 5 = 4x + 20

Subtract 5 from both side

y + 5 – 5 = 4x + 20 – 5

y = 4x + 15

Therefore, Khairul's uncle present age is 4x + 15
