Joyce paid $94.50 for an item at the store that was 55 percent off the original price. What was the original price?

Answers

Answer:

$210

Step-by-step explanation:

The original price of the item = 100%

If the item was reduced by 55%, then the discounted price of the item = 100% - 55% = 45%

Therefore, $94.50 = 45% of the original price.

45% = 45/100 as a ratio

Using ratios, and letting [tex]x[/tex] be the original price:

94.50/[tex]x[/tex] = 45/100

Cross multiply: 94.50 x 100 = 45 x [tex]x[/tex]

9450 = 45[tex]x[/tex]

Divide both sides by 45: 210 = [tex]x[/tex]

Therefore, the original price of the item was $210

Alternatively, divide 94.50 by 45 to get the cost per 1%. Then multiply this by 100 to get the original price (100%):

(94.50 ÷ 45) x 100 = 210

A radio tower 200 ft. high casts a shadow 75 ft. long. What is the angle of elevation of the sun?

Answers

Angle of elevation of the sun: 69 degrees

Step-by-step explanation:

tan(x) = 200/75

x = tan^-1 (200/75)

x = 69 degrees

The angle of elevation of the sun is .

What is tangent of an angle?

The tangent of an angle is the ratio of height to base of the angle.

If we take the angle as Ф, then tan Ф = height/base.

Given, length of the tower is 200 ft. and the length of the shadow is 75 ft.

Let, the angle of elevation of the sun = Ф

Therefore, tan Ф = height/base = 75/200 = 0.375

Hence, Ф = [tex]tan{-1}[/tex](0.375) =

The angle of elevation of the sun is .

what is 5 1/3 divided by 1 1/6

Answers

Answer:

32/7 or 4 4/7

Step-by-step explanation:

I used mathaway. JOKING!

Convert the fractions into mixed numbers.

So instead of 5 1/3 and 1 1/6

you will have 16/3 and 7/6

Apply the fraction rule

a/b ÷ c/d = a/b × c/d

= 16/1 x 2/7

then:

16 x 2

1 x 7

= 32/7

proper fraction: 4 4/7

Kardal did a study to determine the correlation between men’s heights, x, and their shoe sizes, y, and found the following data:

Kardal used the line of best fit to predict that a man 80 inches tall would wear about a size 16 shoe. What can be concluded about this prediction? Check all that apply.

The prediction is reasonable.
The prediction is an interpolation.
No data is given in the scatterplot for a height of 80 inches, but a shoe size can still be predicted.
A prediction cannot be made for a man who is 80 inches tall.
A man who is 80 inches tall will likely wear a size 12.5 shoe.

Option A ,C.

What can be concluded about this prediction?

Generally, the equation for the equation of the line is mathematically given as

y=0.377x-14.214

Where the value of R^2 =0.7784 and x=80

y=0.377x-14.214

Hence

y=0.377(80)-14.214

y=16

In conclusion, Although no data is provided in the scatterplot for a height of 80 inches, a shoe size may still be estimated.

Answers

The new player's personal time is 4.5 seconds.

What is the new player's personal time?

The first step is to determine the total time the 5 persons complete the dash.

Total time = 5 x 5.7 = 28.5 seconds

The second step is to determine the total time for the 6 people to complete the dash.

Total time = 6 x 5.5 = 33 seconds

The third step is to find the difference of the time in the previous two steps: 33 - 28.5 = 4.5 seconds
