What is the distance between R(5,2) and S(4,-7)? Round to the nearest tenth.

1 answer:

5 0

You can calculate the distance between two point using this fomula:

√(x_2-x_1)^2+(y_2-y_1)^2

If you insert you values you get:

√(4-5)^2+(-7-2)^2 = 9.06 = 9.1

72 is what percent of 45?<br><br> __ = p/100<br><br> p= __

Marta_Voda [28]

Answer:

72 of 45 is 160%

Step-by-step explanation:

72 of 45 can be written as:

$\frac{72}{45}$

To find percentage, we need to find an equivalent fraction with denominator 100. Multiply both numerator & denominator by 100

$\frac{72}{45} *\frac{100}{100}$

$=(\frac{72*100}{45} )*\frac{1}{100} =\frac{160}{100}$

Therefore, the answer is 160%

If you are using a calculator, simply enter 72÷45×100 which will give you 160 as the answer.

What 2 numbers multiply to -3 and add to negative 2

-3* 1 = -3

-3 +1 =-2

(m-3) (m+1) =0

Using the zero product property

m-3 = 0 m+1 =0

m=3 m=-1
