Answer:

475

Step-by-step explanation:

Let's call the dryer price is x

Then, the price for the washer is 53 more than the dryer, it would be: x+53

Total price of washer and dryer = 1003

We get the equation:

x+(x+53) = 1003

2x + 53 = 1003

2x + 53 - 53 = 1003 - 53

2x = 950

x = 475

The dryer price is 475

Extra: you can find the cost of the washer by using x+53 = 475+53 = 528

Suppose that water is pouring into a swimming pool in the shape of a right circular cylinder at a constant rate of 3 cubic feet

gtnhenbr [62]

Answer:

Therefore the height of the water in the pool changes at the rate of $\frac{1}{3\pi}$ feet per minute.

Step-by-step explanation:

Given that the shape of swimming pool is right circular cylinder.

The rate of water pouring in the pool = 3 cubic feet per minute.

It means the rate of change of volume is 3 cubic feet per minute.

$\frac{dv}{dt}=3$ cubic feet per minute.

When the volume of the swimming pool changed it means the height of the water level of the pool change and the radius of the swimming pool remains constant.

Let the height of the pool be h.

The volume of the pool is = $\pi 3^2 h$ cubic feet

$=9\pi h$ cubic feet

Therefore,

v $=9\pi h$

Differentiating with respect to t

$\frac{dv}{dt}= 9\pi \frac{dh}{dt}$

Putting $\frac{dv}{dt}=3$

$3=9\pi \frac{dh}{dt}$

$\Rightarrow \frac{dh}{dt} =\frac{3}{9\pi}$

$\Rightarrow \frac{dh}{dt} =\frac{1}{3\pi}$

The change of height of the pool does not depend on the depth of the pool.

Therefore the rate of change of height of the water in the pool is $\frac{1}{3\pi}$ feet per minute.

Please can you give me the answer in standard form

Shalnov [3]

Answer:

$1. (5 \times 10^3) \times (9 \times 10^7) = 45 \times 10^{10}\\2. (7 \times 10^5) \div (2 \times 10^2) = 3.5 \times 10^3$

Step-by-step explanation:

Here, the given expressions are:

$1. (5 \times 10^3) \times (9 \times 10^7)\\2. (7 \times 10^5) \div (2 \times 10^2)$

Now, the LAWS OF EXPONENTS state that:

$1. a^ m \times a^n = a^{(m+n)}\\ 2. a^m \div a^n = a ^{(m-n)}$

Using above laws, we get:

$1. (5 \times 10^3) \times (9 \times 10^7)\\= (5 \times 9 ) \times ( 10^7\times 10^3)\\= 45 \times (10^{(7+3)}) = 45 \times 10^{10}\\\implies (5 \times 10^3) \times (9 \times 10^7) = 45 \times 10^{10}$

$2. (7 \times 10^5) \div (2 \times 10^2)\\= \frac{(7 \times 10^5)}{(2 \times 10^2)} = \frac{7}{2} \times\frac{10^5}{10^2} \\ =3.5 \times 10^{(5-2)} = 3.5 \times 10^3\\\implies(7 \times 10^5) \div (2 \times 10^2) = 3.5 \times 10^3$
