Find The Length Of The Missing Side Please Help

Answers

Answer 1

Step-by-step explanation:

7. Since they are similar triangles we have:

[tex] \frac{10}{8} = \frac{x}{12} \\ \\ x = 15[/tex]

So DF is 15

8. They are also similar. So:

[tex] \frac{14}{7} = \frac{x}{5} \\ x = 10[/tex]

So PR is 10

Is the data set approximately periodic? If so, what are its period and amplitude?

Answers

Considering the given table and the periodicity concept, it is found that the data set is not periodic.

What is the period of a data-set?

The period of a function is given by the distance between it's repetitions.

An example of a periodic data-set with a period of 3 would be 1,2,3,1,2,3,1,2,3,...

In this problem, looking at the table, it is found that there are no patterns of repetitions, that is, the number of cars washed do not follow a repeated pattern, hence the data set is not periodic.

Mr. Wilson wants to buy a new
computer. The regular price is
$1,049. Mr. Wilson has a 20% off
coupon. After using the coupon,
he must pay a sales tax of 5.25%.
What is the final cost of the
computer?

Answers

1. Find how much the 20% discount is.
1049*.20= 209.8

Subtract that from the original price.
1049-209.8=839.2

2. Find the sales tax of the computer after the discount.
839.2*.0525=44.058

Add that to your discounted total.
839.2+44.058=883.258

So the final cost would be $883.26

Find the nth term of this number sequence
7, 10, 13, 16, ...

help please !!

Answers

Answer:

[tex]a_{n}[/tex] = 3n + 4

Step-by-step explanation:

there is a common difference between consecutive terms , that is

10 - 7 = 13 - 10 = 16 - 13 = 3

this indicates the sequence is arithmetic with nth term

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

here a₁ = 7 and d = 3 , then

[tex]a_{n}[/tex] = 7 + 3(n - 1) = 7 + 3n - 3 = 3n + 4

Answer:

The nth term = 3n + 4.

Step-by-step explanation:

The formula for the nth term of an arithmetic progression is a(n) = dn + a(1) - d.

So this breaks down simply to,

a(n) = dn + a(1) - d a(n) = 3n + 7 - 3 a(n) = 3n + 4

What is the slope of the line that passes through the points (4, 7) and (8, 9)

Answers

Answer:

y = 0.5x + 5

Step-by-step explanation:

Use the slope formula to find the slope of a line given the coordinates of two points on the line.

The slope formula is:

m = [tex]\frac{y{2}-y{1} }{x{2}- x{1} }[/tex] = [tex]\frac{y}{x}[/tex]

The coordinates of the first point represent x1 and y1. The coordinates of the second points are x2, y2.

Now let's fill in the formula with the points,

m = [tex]\frac{8-4}{9-7}[/tex]

Solve,

⇒ Y = 9 – 7 = 2

⇒ X = 8 – 4 = 4

m = [tex]\frac{8-4}{9-7}[/tex] = [tex]\frac{2}{4}[/tex]

Simplify,

⇒ [tex]\frac{2}{4}=\frac{1}{2}=0.5[/tex]

Therefore, the Equation of the line is y = 0.5x + 5.

Answers

The mean, median, and mode of the given data are 89, 92 and 82 respectively.

Measure of dispersion

The measures of dispersion that we have are the mean, median and the mode.

The mean is the average of the given data

Mean = Sum/sample size

Mean = 96+81+82+99+94+92+95+82+80/9

Mean = 801/9

Mean = 89

Determine the median

Median is the middle value after rearrangement

80, 81, 82, 82), 92, (94, 95, 96, 99

Hence the medianof the data is 92

Calculate the mode

Mode is the number occuring the most. Since 82 occurs the most, hence the mode is 82

Under his cell phone plan, Oliver pays a flat cost of $49 per month and $5 per gigabyte. He wants to keep his bill at $73.50 per month. How many gigabytes of data can he use while staying within his budget?

Answers

Four gigabytes (4.9)

$73.5-$49=$24.5
$24.5/$5 =4.9

He must consume only 4.9 gigabytes to maintain his bill at $73.50 per month.

What is arithmetic?

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,

Here,
According to the question,
Oliver pays a flat cost of $49 per month and $5 per gigabyte.
Let the number of gigabytes he consumes be x,
He wants to keep his bill at $73.50 per month. So,
49 + 5x = 73.50
5x = 73.50 - 49
x = 24.5/5
x = 4.9

He must not consume less or more than 4.9 gigabytes to maintain his bill at $73.50 per month.

Thus, he must consume only 4.9 gigabytes to maintain his bill at $73.50 per month.
