A store sells memory cards for $25 each.


The markup for each memory card is 25%. How much did the store pay for 50 memory cards?

Answers

Answer:

$937.50

Step-by-step explanation:

25 decrease 25% =

25 × (1 - 25%) = 25 × (1 - 0.25) = 18.75

18.75 × 50 = 937.50

The amount that the store pays for 50 memory cards will be $1,000.

What is the percentage?

The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates to one hundred percent. It is symbolized by the character '%'.

The percentage is given as,

Percentage (P) = [Final value - Initial value] / Initial value x 100

A store sells memory cards for $25 each. Then the cost price of each memory card is given as,

⇒ $25 / 1.25

⇒ $20

The amount that the store pays for 50 memory cards will be given as,

⇒ $20 x 50

⇒ $1,000

The amount that the store pays for 50 memory cards will be $1,000.

TUJ = 29

Step-by-step explanation:

178-149

Answer:

m∠ TUJ = 29°

Step-by-step explanation:

Although this question looks hard, it really is not.

Since we know that TUV = 178° and we know that JUV = 149° we can easily figure out TUJ.

First, since we know that the total is 178° (TUV) we can subtract angle JUV from TUV to get TUJ

178° - 149° = ?

178° - 149° = 29°

What is the percent increase from 50 to 69

Answers

Detailed answer:
A change from 50 to 69 represents a positive change (increase) of 38%
Use the formula found below on this webpage to find the percent change by replacing the given values:
Percent change = New - Old
|Old|
× 100%
Percent change = 69 - 50
|50|
× 100% =
19
50
× 100 = 38% (increase)
Where: 50 is the old value and 69 is the new value. In this case we have a positive change (increase) of 38 percent because the new value is greater than the old value.
This is a simple feat to figure out.

First find the difference between 69 and 50.

69 - 50 = 19


Now to find the decimal, divide 19 by 50 which would equal 0.38. And to find the percentage, move the decimal two spaces to the right.

A gift store owner used 9 rolls of wrapping paper to wrap his customers’ gifts last week. Each roll was 66 1/2 in. long. How many gifts did he wrap if a 9 1/2 in. long piece of wrapping paper was used to wrap each gift?

Answers

Answer:

Answer is 7

Step-by-step explanation:

If the roll was 66 1/2 rolls long, we have to calculate and know how many pieces of wrapping paper for the roll so if each wrapping paper is 9 1/2 then you would have to divide 66 1/2 by 9 1/2 so you would need 7 wrapping papers.

8/3 meters (I wrote it as an improper fraction to avoid the hassle of writing repeating decimals)

Step-by-step explanation:

Don't try to include the timber in this problem. It is unnecessary. So, let's focus on the fact that the triangle with 3cm, 1.6m, and a portion of the timber is similar to the triangle with (3+2) cm, ?m, and the full length of the timber. Now, to find the ratio; we know that the side with 3 cm is similar to the side in the other triangle with a measure of 3+2=5 cm. So the ratio is 5/3. Now, we want to find out how far up the timber will go up the wall. This means you want to find the vertical measurement. So, multiply 1.6 (8/5) by 5/3, equaling 8/3.

Answers

1 yd = 3 ft

48 in = 2 ft

10,560 ft = 2 mi

5 ft = 60 in

3 m = 300 cm

24 in = 2 ft

3 ft = 36 in

4 yd = 12 ft

3 mi = 15840 ft

24 ft = 8 yd

8 km = 8000 m

6 cm = 60 mm

1 yd = 36 in

2 yd = 72 in

200 cm = 2 m

Henry places £6000 in an account which pays 4.6% compound interest each year
Calculate the amount in his amount after 2 years

Answers

Answer:

£ 6,564.70

Step-by-step explanation:

Henry places £6000 in an account which pays 4.6% compound interest each year. Calculate the amount in his amount after 2 years

Compound Interest formula =

A = P(1 + r/n)^nt

A = Final Amounrt

P = Principal = £6,000

r = Interest rate = 4.6%

t = Time in years = 2 years

n = Compounding frequency = Yearly = 1

First, convert R percent to r a decimal

r = R/100

r = 4.6%/100

r = 0.046 per year,

Then, solve our equation for A

A = P(1 + r/n)^nt

A = 6,000.00(1 + 0.046/1)^(1×2)

A = £ 6,564.70

The amount in his account after 2 years = £ 6,564.70
