If the polygons are similar then the sides are in proportion.

$\dfrac{32}{24}=\dfrac{32:8}{24:8}=\dfrac{4}{3}$

Therefore we have the equations:

$\dfrac{x-1}{6}=\dfrac{4}{3}\qquad\text{cross multiply}\\\\3(x-1)=(4)(6)\\\\3x-3=24\qquad\text{add 3 to both sides}\\\\3x=27\qquad\text{divide both sides by 3}\\\\\boxed{x=9}$

$\dfrac{y+1}{21}=\dfrac{4}{3}\qquad\text{cross multiply}\\\\3(y+1)=(21)(4)\\\\3y+3=84\qquad\text{subtract 3 from both sides}\\\\3y=81\qquad\text{divide both sides by 3}\\\\\boxed{y=27}$

Write the subtraction expression as an equivalent addition expression and then evaluate it.

Harrizon [31]

Answer:

Step-by-step explanation:

Given the expression -3-(-5)

This is also expressed as;

-3(-5)

= -3 + 5 (The product of two negative sign gives a positive sign)

= 5 - 3

= 2

Hence the result of the expression is 2

IF S.P. = Rs 1,869, loss percent = 11% find C.P.

Veseljchak [2.6K]

Here,

Selling Price (S.P) = Rs 1869

Loss = 11%

Cost Price (C.P) = ?

Let, C.P be x

Now,

Sp = Cp - loss% of Cp

1869 = x - 11/100*x

1869 = (100x - 11x)/100

186900 = 89x

◆ x = Rs 2100

Cp = Rs 2100

I hope you understand...

It's a Right answer...

Thanks♥♥

"Use the following information to answer the question. The mean age of lead actresses from the top ten grossing movies of 2010 w

julia-pushkina [17]

Answer:

a) 10.6; 48.7; within

Step-by-step explanation:

The Empirical Rule states that, for a normally distributed random variable:

68% of the measures are within 1 standard deviation of the mean.

95% of the measures are within 2 standard deviation of the mean.

99.7% of the measures are within 3 standard deviations of the mean.

In this problem, we have that:

Mean = 29.6

Standard deviation = 6.35

"According to the Empirical Rule, the ages of nearly all lead actresses will be between______________and_____________ years.

Nearly all(99.7%) will be within 3 standard deviations from the mean.

So from 29.6 - 3*6.35 = 10.6 years to 29.6 + 3*6.35 = 48.7 years.

Anna was 11-years old, so she was within this range.

So the correct answer is

a) 10.6; 48.7; within
