Answer:

  10°, 80°

Step-by-step explanation:

<em><u>Setup</u></em>

Let x and y represent the measures of the two acute angles in the right triangle.

From your knowledge of right triangles, you know the two acute angles are complementary:

  x + y = 90

The problem statement gives you another relation:

  x = 2(y + 30) . . . . twice the sum ...

__

<em><u>Solution</u></em>

The second equation gives you an expression for x that can be substituted into the first equation.

  (2(y +30)) + y = 90

  3y +60 = 90 . . . . . . . . collect terms

  3y = 30 . . . . . . . . . subtract 60

  y = 10 . . . . . . . . divide by 3

  x = 2(y +30) = 2(40) = 80

The two angles are 10° and 80°.

The function c = 100 + 0.30m represents the cost c (in dollars) of renting a car after driving m miles. What would the cost be t
aleksley [76]

Answer:

c = $130

Step-by-step explanation:

Given:

c = 100 + 0.30m

Where,

c = cost of renting a car (in dollars)

m = number of miles driven (in miles)

If m = 100 miles

c = 100 + 0.30m

= 100 + 0.30(100)

= 100 + 30

= 130

c = $130

What’s the combined average of Altuve’s weighted average below:
Fynjy0 [20]

Answer:

<em>The combined average of Altuve's weighted averages is 1 for 2 or 1/2</em>

Step-by-step explanation:

<u>Combined Average</u>

On Friday, Altuve had 3 out of 5 successes

On Saturday, Altuve had 2 out of 4 successes

On Friday, Altuve had 1 out of 3 successes

The total successes are 3+2+1=6

The total tries are 5+4+3=12

The combined average is:

\displaystyle \bar x=\frac{6}{12}

Simplifying:

\displaystyle \bar x=\frac{1}{2}

The combined average of Altuve's weighted averages is 1 for 2 or 1/2
