Answer:

$70
y = 25 + 0.9x
$250

Step-by-step explanation:

1. 10% of $50 is $5, so the purchases would come to $50 -5 = $45. Added to the $25 membership fee, the total cost for the year would be

$45 +25 = $70

2. The member pays $25 even if no purchases are made. Then any purchases are 100% - 10% = 90% of the marked price. So, the total is ...

y = 25 + 0.90x

3. $25 is 10% of $250, so that is the amount the member would have to purchase to break even on cost.

If you like, you can compare the cost without the membership (x) to the cost with the membership (25+.9x) and see where those costs are equal.

x = 25 +0.9x . . . . . x is the spending level at which there is no advantage

0.1x = 25 . . . . . . . . subtract 0.9x

25/0.1 = x = 250 . . . divide by 0.1

Complementary Angles - Angles that add up to 90°

Step-by-step explanation:

Step 1: Set Up Equation

The 2 angles must add up to 90°.

(8m + 4)° + 38° = 90°

Step 2: Solve for m

Combine like terms: 8m + 42 = 90
Isolate m term: 8m = 48
Isolate m: m = 6

what is the slope of the line that passes through the points (-4,-4) and (-4,-9)? Write your answer in simplest form

Aneli [31]

Answer:

undefined

Step-by-step explanation:

We can find the slope of a line using two points by

m = (y2-y1)/(x2-x1)

= (-9- -4)/(-4 - -4)

= (-9+4)/(-4+4)

= -5/0

When we divide by zero, our solutions is undefined

The slope is undefined

The centre of the stained glass window is in the shape of a regular polygon. What are the measures of the interior angle of the

tester [92]

Answer:

67.5 - 67.5 - 45 °

Step-by-step explanation:

Sum of INTERIOR angles of a polygon

(n-2) * 180 <====ya just have to remember/know this !

n is the number of sides n = 8 in this case

(8-2)*180 = 1080 ° < === this is the SUM of the 8 interior angles

EACH interior angle is then 1080 / 8 = 135 °

you can see from the picture that each of the two outside angles of the green triangle are 1/2 of this = 67.5° each

so the triangle measurements are

67.5 - 67.5 - 45 ( they have to sum to 180 for triangle)

The yearbook club had a meeting. The meeting had 8 people, which is one-fourth of the club. How many people are in the club?

nataly862011 [7]

Answer:

Step-by-step explanation:

Since we know 8 = 1/4

We can convert the 1/4 into a percentage:

8 = 25%

To get to 100% which is the full club we have to multiply both sides by 4:

8×4 = 25% ×4

32 = 100%

So there are 32 people in the club.
