Answer:

A B C are all correct yuhh

Step-by-step explanation:

No it won't. it's false

cuz proofs here.

(5²)+(12²)= (169)

√(169) = 13

.. so if 13 was the number at 14

it would have been true.

currently the answer is false

Answer:

The answer to the question provided is 60.

Answer:

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]

Answer:

the answer is the option B

b(x) has the highest value in  years; b(x) has the highest value in  years

Step-by-step explanation:

x------> the time in years

b(x)----> the value in dollars of a saving account

c(x)----> the value in dollars of another account

we know that

Step 1

Find the value of each account for

so

----> b(x) has the highest value in  years

Step 2

Find the value of each account for

so

----> b(x) has the highest value in  years

Second table (B)

Input: 0, 1, 2

Output: -3, 1, 5

Explanation:

Given the 2D linear equation y = 4x - 3,

y must represent the output because it is the dependent variable, so x must represent the input because it is a independent variable.

Answer:

Do you mean solve for t?

If you do, the answer is 9.

Step-by-step explanation:

If we expand the equation out, we get:

-t = 9t - 90

If we move the -90 over to the left side and the -t to the right side, we get:

90 = 10t

Dividing both sides by 9, we get:

t = 9

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

Answer:

  9π ≈ 28.3 square meters

Step-by-step explanation:

Using the given formula for the area of the circle, we find its area to be ...

  A = πr^2

  A = π(3 m)^2 = 9π m^2 ≈ 28.3 m^2

The dog has about 28.3 square meters to run around in.

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]

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

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

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

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

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

[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]

3.110.41

Step-by-step explanation:

Answer:

Shape 1: 96.04

Shape 2: 110.41

Shape 3: 75.43

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.
