Hi,

To find the cost before tax, we must find out how much the tax is. So we multiply 252 x .05 to get 12.6. So we know the tax was 12.6 dollars. Now all we have to do is subtract that from the total to get our answer. 252 - 12.6 = 239.4.

Have a great day!

The formula for the perimeter, P, of a rectangle is P = 2L + 2w, where L is the length and W is th width sovle the formula for t

vichka [17]

P = 2L + 2w

Subtract 2L
from each side: P - 2L = 2w

Divide each side
by 2 : (P - 2L) / 2 = w

You could also write it as (P/2 - L) = w
Both answers are the same.

Answer:

m=45

RPS =45

Step-by-step explanation:

the sum of angles of triangle=180 degrees

90+45+m=180

triangle PST is the image of triangle PQR

m=180-135=45 degrees

Angle RPS = 45 degrees ( two angles are adjacent when they have common side, ad do not overlap )

Answer:

Rs 1350

Step-by-step explanation:

An average of 5 shirts is Rs 750

The total amount of the 5 shirts is 750×5

= 3,750

The price of 3 shirts is Rs 2400

Therefore the price of the other two shirts can be calculated as follows

= 3750-2400

= 1350

Hence the price of the other two shirts is Rs 1350

The formula for the volume of a sphere is the following:

$V= \dfrac{4}{3} \pi r^3$

Plug in V=5000π and solve for the radius.

$5000 \pi = \dfrac{4}{3} \pi r^3$

Divide both sides by $\pi$

$5000 = \dfrac{4}{3} r^3$

Multiply both sides by 3/4 (to eliminate the 4/3 on the right side)
Also, flip the equation so we have the unknown variable on the left side (math etiquette).

$r^3=3750$

Take the cube root of both sides

$r \approx 15.5$

Now, calculate the surface area since now we know the radius.
The formula for the surface area is the following:

$S=4 \pi r^2$

Plug in r=15.5

$S \approx 3033$

The second choice is your answer.
