Answers

Answer:

9.0, 9.012, 9.201, 9.210

Step-by-step explanation:

9.0 has no decimal numbers, so it goes at the beginning, 9.012 is the next greatest, then 9.201, and finally, 9.21. Also, a zero at the end of a decimal number adds nothing.

9.0 , 9.012 , 9.201 , and greatest is 9.210 hope this helps

Select the reason why these triangles are
similar. If they are not, select "Not similar".
A. AA
B. SAS
C. SSS
D. Not similar

Answers

Answer:

B. SAS

Step-by-step explanation:

In the given diagram, it would be observed that each side of the bigger triangle are multiplied by a factor of [tex]\frac{1}{3}[/tex] to give the values of each corresponding sides of the smaller triangle. But the included angle of the two triangles are the same.

Therefore, the reason why the triangles are similar is because of side-angle-side (SAS) relations. The correct option is B.

The video streaming service that you want to use is represented with the equation
below, where y represents the the total monthly cost of the service and x represents
the number of videos you plan to stream each month:
y = $1.25x + $5.00
Create a table for the values when x = 0, 5, 8, 10, 30
x-value
y-value
0
5
8
10
30

Answers

Answer:

HERES THE ANSWER

Step-by-step explanation:

0 = 5.00

5 = 11.25

8 = 15.00

10 = 17.50

30 = 42.50

also to understand it easier. # 1.25 times (whatever number), then take whatever that equals and add it to 5.00 ! (works for any question, just substitute the numbers)

To create a table for the values when x is given value, you can put those value in given function and can calculate what does y evaluates to.

The corresponding values of y are:

[tex]\begin{array}{cc}x&y\text{(In dollars)}\\0&5\\5&11.25\\8&15\\10&17.5\\30&42.5\end{array}\right[/tex]

Given that:y represents the total monthly cost to the servicex represents the number of videos you plan to stream each month. y = $1.25x + $5.00 ( a linear function )To find:

Values of y for values of x as x = 0, 5, 8, 10, 30

Using the relation between y and x to find the values of y to corresponding values of x:

For x = 0:

[tex]y = 1.25x + 5\\ \\ y = 1.25x + 5|_{x=0}\\ y = 1.25 \times 0 + 5\\ y = \$5\\ \\ [/tex]

For x = 5:

[tex]y = 1.25x + 5\\ \\ y = 1.25x + 5|_{x=5}\\ y = 1.25 \times 5 + 5\\ y = \$11.25\\ \\ [/tex]

For x = 8:

[tex]y = 1.25x + 5\\ \\ y = 1.25x + 5|_{x=8}\\ y = 1.25 \times 8 + 5\\ y = \$15\\ \\ [/tex]

For x = 10:

[tex]y = 1.25x + 5\\ \\ y = 1.25x + 5|_{x=10}\\ y = 1.25 \times 10 + 5\\ y = \$17.5\\ \\ [/tex]

For x = 30:

[tex]y = 1.25x + 5\\ \\ y = 1.25x + 5|_{x=30}\\ y = 1.25 \times 30 + 5\\ y = \$42.5\\ \\ [/tex]

Thus, the corresponding values are:

[tex]\begin{array}{cc}x&y\text{(In dollars)}\\0&5\\5&11.25\\8&15\\10&17.5\\30&42.5\end{array}\right[/tex]

2. What is the area of a circle with a radius of a 8 yd using 3.14 as pi?

3. The area of a circle in terms of pi is 49pi. What is the radius of the circle?

Help needed and it would be appreciated

Answers

Answer:

1. 100pi cm

2. 200.96 yd

3. 7

Step-by-step explanation:

1.) diameter = radius multiple by two (D = r × 2)

&

radius = diameter divided by two (r = D ÷ 2)

So

20 ÷ 2 = 10 => A = pi (10)power 2 => A = 100pi

---------------------------------------------------------------------------------------------

2.) 3.14 × (8)power2 =200.96

---------------------------------------------------------------------------------------------

3.) A = 49pi => 49pi = pi(r)power2

[ cross out the pi from both sides]

And your left with

49 = (r)power2

[square root both sides to get rid of the power]

And your left with

7 = r

Step-by-step explanation:

For shape 1, you can do 9.8*9.8 and get the answer of 96.04. For shape 2, you can do 6.1*18.1 to get the answer of 110.41. Finally for shape 3, you can find the whole circle and divide it by 4 because it is only a quarter of the circle. The radius being 9.8, you then get the area of 301.72. But since its only a quarter of a circle you divide by 4 and get 75.43.

A) 7 is the greatest common factor of the expression.

B) factoring the expression [tex]14x + 28y + 21[/tex] we get [tex]\mathbf{7(2x+4y+3)}[/tex]

Step-by-step explanation:

We are given the expression: [tex]14x + 28y + 21[/tex]

Part A: What is the greatest common factor of the expression?

We need to find the greatest common factor of the expression.

The expression is divisible by 7

So, 7 is the greatest common factor of the expression.

Part B: Factor the expression

We need to factor the expression: [tex]14x + 28y + 21[/tex]

Taking 7 common:

[tex]14x + 28y + 21\\=7(2x+4y+3)[/tex]

So, factoring the expression [tex]14x + 28y + 21[/tex] we get [tex]\mathbf{7(2x+4y+3)}[/tex]
