if a triangle has a area of 42 cm^2 and a base of 8 cm, what is the height?



show work plsssss

Answers

Answer 1

Answer:

The height would be 10.5 cm

Answer 2

Answer:

hb=10.5cm

Step-by-step explanation:

Area of triangle = 1/2(height x base)

The problem states that base is 8 cm greater than the height; therefore, base-8 = height.

A = 1/2(b*h)

42 = 1/2(b*[b-8])

84=(b^2-8b)

rearrange to

b^2 - 8b -84

factor to

(b+8)(b-14)

Therefore, b = -8 cm which makes no sense and

b = +14 cm

and height = 14-8 = 6

Check:

1/2(b*h) = area

1/2(14*6) = 1/2(84)=42

Find the interquartile range (IQR) and list any outliers: 60, 74, 70, 70, 50, 62, 54, 89, 67, 88, 82, 74 A. IQR = 39: 89 is an outlier B. IQR = 17: no outliers C. IQR = 39: no outliers D. IQR = 17: 50 is an outlie

Answers

Given:

The data set is 60, 74, 70, 70, 50, 62, 54, 89, 67, 88, 82, 74.

To find:

The IQR and outliers.

Solution:

The given data set is

60, 74, 70, 70, 50, 62, 54, 89, 67, 88, 82, 74

Arrange the data values in ascending order.

50, 54, 60, 62, 67, 70, 70, 74, 74, 82, 88, 89

Divide the data set in two equal parts.

(50, 54, 60, 62, 67, 70), (70, 74, 74, 82, 88, 89)

Divide each parentheses in two equal parts.

(50, 54, 60), (62, 67, 70), (70, 74, 74), (82, 88, 89)

Now,

[tex]Q_1=\dfrac{60+62}{2}[/tex]

[tex]Q_1=\dfrac{122}{2}[/tex]

[tex]Q_1=61[/tex]

And,

[tex]Q_3=\dfrac{74+82}{2}[/tex]

[tex]Q_3=\dfrac{156}{2}[/tex]

[tex]Q_3=78[/tex]

We know that, the inter quartile range is

[tex]IQR=Q_3-Q_1[/tex]

[tex]IQR=78-61[/tex]

[tex]IQR=17[/tex]

The IQR is 17.

If the data values lie outside the interval [tex][Q_1-1.5IQR,Q_3+1.5IQR][/tex], then those values are known as outliers.

[tex][Q_1-1.5IQR,Q_3+1.5IQR]=[61-1.5(17),78+1.5(17)][/tex]

[tex][Q_1-1.5IQR,Q_3+1.5IQR]=[35.5,103.5][/tex]

All data values lie in the interval [35.5,103.5]. So, there are no outliers.

Therefore, the correct option is B.

Use scientific notation to estimate the number of inches in 1,225 miles. Include all calculations in your final answer. 1 inch =1578x 10-5 miles

Answers

Answer: (7.129)*10^(7) inches.

Step-by-step explanation:

We know that:

1 inch = 1.578*10^(-5) miles.

If we divide both sides by 1.578*10^(-5), we get:

(1/1.578*10^(-5)) inches = 1 mile

63,371.36 inches = 1 mile

Now, we have 1,225 miles, this is equal to 1,125 times 63,371.36 inches

Then 1,225 miles writen in inches is:

1,125*(63,371.36 inches) = 71,292,780 inches.

Now, to write this in scientific notation, we need to count the number of decimals between the first one at the left, and the decimal point.

In this case we have 7 decimals.

Now, let's take the first 4 decimals, (7129) and write a decimal point after the first one:

(7.129)

Now let's multiply this by then to the power of 7 (where 7 is the number of decimals we found above).

Then the scientific notation of 71,292,780 inches. is:

(7.129)*10^(7) inches.

Jack and Jill applied for the same credit card from the same bank. The bank checked both of their FICO scores. Jack had an excellent credit rating, and

Jill had a poor credit rating


Jack was approved for a card with an APR of 12%. What was his monthly periodic rate?


Jill was approved for a card with an APR of 21%. What was her monthly periodic rate?


If each of them had an average daily balance of $700 and had to pay a finance charge, how much MORE will Jill pay than Jack?

Answers

Answer:

a. Jack's monthly periodic rate = 1%

b. Jill's monthly periodic rate = 1.75%

c. Amount paid more by Jill than Jack = $5.25

Step-by-step explanation:

a. Jack was approved for a card with an APR of 12%. What was his monthly periodic rate?

Jack's monthly periodic rate = Jack's annual percentage rate (APR) / Number of months in a year = 12% / 12 = 1%

b. Jill was approved for a card with an APR of 21%. What was her monthly periodic rate?

Jill's monthly periodic rate = Jill's APR / Number of months in a year = 21% / 12 = 1.75%

c. If each of them had an average daily balance of $700 and had to pay a finance charge, how much MORE will Jill pay than Jack?

Jack's finance charge = Jack's monthly periodic rate * Average daily balance = 1% * $700 = $7

Jill's finance charge = Jill's monthly periodic rate * Average daily balance = 1.75% * $700 = $12.25

Amount paid more by Jill than Jack = Jill's finance charge - Jack's finance charge = $12.25 - $7 = $5.25

30 POINTS According to this document, how did the Homestead Act encourage the settlement of the West?In 1862, the Homestead Act was passed and signed into law. The new law established a three-fold homestead acquisition process: filing an application, improving the land, and filing for deed of title. Any U.S. citizen, or intended citizen, who had never borne arms against the U.S. Government, could file an application (for free land), improving the land and lay claim to 160 acres of surveyed Government land. For the next 5 years, the homesteader had to live on the land and improve it by building a 12-by-14 dwelling and growing crops. After 5 years, the homesteader could file for his patent (or deed of title) by submitting proof of residency and the required improvements to a local land office. 4. 8 16,Find the next 3 term of geometric sequence JKLM is a rhombus.
