The owner of an audio store received a shipment of portable stereos at a cost of $88.90 each. If he sells the stereos for $152.99 each, what is the percent of markup? Round to the nearest whole percent.

Answers

He would get a profit of 64.09
64.09 or 64% because if you subtract 152.99 from 88.90 you get 64.09 and you round it to 64% because the 0 is under 5 so you lower it

Answers

Answer:

3

Step-by-step explanation:

Since

3 : 2 = X : 2

Then we know

3/2 = X/2

Multiplying both sides by 2 cancels on the right

2 × (3/2) = (X/2) × 2

2 × (3/2) = X

Then solving for X

X = 2 × (3/2)

X = 3

Therefore

3 : 2 = 3 : 2

2.396 liters
239.6 liters

23,960 liters

Answers

2.396 which is also a.

Answer:

2.396

Step-by-step explanation:

The units of measurement go like this:

Kilo, hecto, deca, unit, deci, centi, mili

When you move to the right, you move the decimal one place to the right, and when you move left, you move the decimal one place to the right

If you’re changing milliliters to liters (unit), you have to more the decimal 3 times to the left. This makes it 2.396 liters

Answer:

15*C

Step-by-step explanation:

The temperature rises by 2.4 every 3 cycles per second. So you would have to keep the pattern going.

6 cycles p/second = 19.8*C

3 cycles p/second = 17.4*C

0 cycles p/second = 15.0*C

So, because 0 cycles means the engine is resting, 15*C would be the answer.

15 is the answer .......

As they are right angle triangles and 2 lines are perpendicular.

To find height of any shape we look for perpendicular line this also applies to segments.

Segments as seen below can only be cut off areas of a circle by either a chord touches line as shown second picture, or a secant which is a perpendicular use line . and crosses the line of the circle but is not shown in picture only the chord is.

Secant line still forms a segment but is only used usually with overlapping shapes some which are parallel in geometry solving for tangents or shading.

Answers

Explanation:

The formula y - y1 = m(x - x1) is usually described as the 'point-slope form' for the equation of a line. It is useful because if you know one point on a certain line and the slope of that certain line, then you can define the line with this type of formula and, thus, find all the other points on that certain line.

If its not right im gonna report you

Answers

Answer:

R = -2

Step-by-step explanation

-9, -3 is the first point.

A slope of 1/7 means that for every one unit that "rises" it will have a "run" of 7 units.

-9 - 7 = -2

-3 - 1 = -2 (r)

with a slope of 1/7, (-9, -3) connects to (-2, -2)
