A woman is emptying her aquarium at a steady rate with a small pump. The water pumped to a 12-in.-diameter cylindrical bucket, a

Temka [501]

Answer:

Therefore the rate at which water level is dropping is $\frac{11}{21}$ in per minute.

Step-by-step explanation:

Given that,

The diameter of cylindrical bucket = 12 in.

Depth is increasing at the rate of = 4.0 in per minutes.

i.e $\frac{dh_1}{dt}=4$

$h_1$ is depth of the bucket.

The volume of the bucket is V = $\pi r^2 h$

$=\pi \times 6^2\itimes h_1$

$\therefore V=36\pi h_1$

Differentiating with respect yo t,

$\frac{dV}{dt}=36\pi \frac{dh_1}{dt}$

Putting $\frac{dh_1}{dt}=4$

$\therefore\frac{dV}{dt}=36\pi\times 4$

The rate of volume change of the bucket = The rate of volume change of the aquarium .

Given that,The aquarium measures 24 in × 36 in × 18 in.

When the water pumped out from the aquarium, the depth of the aquarium only changed.

Consider h be height of the aquarium.

The volume of the aquarium is V= ( 24× 36 ×h)

V= 24× 36 ×h

Differentiating with respect to t

$\frac{dV}{dt}=24\times 36 \times \frac{dh}{dt}$

Putting $\frac{dV}{dt}=36\pi\times 4$

$36\pi\times 4= 24\times 36\times \frac{dh}{dt}$

$\Rightarrow \frac{dh}{dt}=\frac{36\pi \times 4}{24\times 36}$

$\Rightarrow \frac{dh}{dt}=\frac{11}{21}$

Therefore the rate at which water level is dropping is $\frac{11}{21}$ in per minute.

Solve this please !! 5-3p=10-8p

Luden [163]

Subtract 5 from both sides

so now it should be like this
-3p=-8p+5

Now add 8p to both sides
now it should look like this
5p=5
now divide
5/5= 1

sp p=1

Mia buys 5 yards of ribbon to make bracelets.She need 18 inches of ribbon to make 1 bracelet. How many bracelet can Mia make if

melisa1 [442]

Divide the total number of yards (5 yards) by the bracelet size (18").

STEP 1:
convert total yards to inches

1 yard= 36 inches

= 5 yards * 36 inches
= 180 inches total

STEP 2:
divide total inches by bracelet size

= 180 ÷ 18 inch bracelet
= 10 bracelets

ANSWER: She can make 10 bracelets.

Hope this helps! :)

The volume of a solid right pyramid with a square base is V units3 and the length of the base edge is y units

statuscvo [17]

Answer with explanation:

Volume of a solid right pyramid with a square base = V (units)³

-------------------------------------(1)

The <u>Solid right pyramid will be in the shape of Cube</u>.

Length of edge of Right Pyramid = y units

So,Volume of Right Pyramid which is in the shape of Cube

= (Side)³

=y³ (Units)³

---------------------------------(2)

Equating (1) and (2)

$\Rightarrow y^3=V$
