Answer:

C) 3

Step-by-step explanation:

combine like terms

=> x^{2+3} × y^{2+?} = x^{5}y^{5}

=> x^{5} y^{2+?} = x^{5}y^{5}

divide x^{5} on both side to eliminate x

=> y^{2+?} = y^{5}

=> y^{2+3} = y^{5}

=> y^{5} = y^{5}

Which pair of ratios form a proportion?
leva [86]

Answer:

D: 5 : 8 and 20 : 32

Step-by-step explanation:

A is incorrect because 3 x 1.33 = 4 and 4 x 1.25 = 5.

B is incorrect because 10 x 1.6 = 16 and 12 x 1.5 = 18.

C is incorrect because 7 x 1.428 = 10 and 10 x 1.4 = 14.

D is correct because 5 x 4 = 20 and 8 x 4 = 32.

another way of solving the ratio answers is by putting them in a fraction 5/8 = .625 and also does 20/32 = .625.....

Easy right!?

Hope I Helped!

4. (10 points) From the given triangle:
katrin2010 [14]

Answer:

sinθ =  y/r        sinθ = \frac{-6}{10} = \frac{-3}{5}

cosθ =  x/r       cosθ = \frac{8}{10} = \frac{4}{5}

tanθ =  y/x       tanθ =  \frac{-6}{8} =\frac{-3}{4}

cscθ =  r/y       cscθ = \frac{-5}{3}

secθ =  r/x       secθ =  \frac{5}{4}

cotθ = x/y       cotθ = \frac{4}{3}

explanation:

r = \sqrt{(8)^{2}+(-6)^{2}  }

r = 10

x = 8

y = -6

r = \sqrt{(4)^{2}+(3)^{2}  }

r = 5

x = 4

y = 3

Jillian worked her 40 regular hours last week, plus 2 overtime hours at a time-and-a-half rate. Her gross pay was $516. What was
Effectus [21]

Its hourly rate of Jillian is 12 hours.

Here we have to find the hourly rate.

Let h be the hourly rate. As it is given that overtime is a time and a half rate.

So the overtime hour is 1.5h.

The total amount Jillian get is $516.

So from this, we get an equation:

40h + 2(1.5h) = 516

40h + 3h = 516

43h = 516

h = 12

Therefore we get the hourly rate as 12.

To know more about the equation refer to the link given below:
