So just divide 27 by 4 1/2 or 4.5, you should get 6 so it would take 6 hours for the snow to get to 27 inches

Answer:

The answer in decimal form is 18.9 so if you convert it to a fraction, the correct answer should be 8 9/10.

The function g(x) = 3x2 − 12x + 7 written in vertex form is g(x) = 3(x − 2)2 − 5. What is the vertex of g(x)?

faltersainse [42]

Answer: The correct option is (C). (2, -5).

Step-by-step explanation: The given function is

$g(x)=3x^2-12x+7.$

The vertex form of the function g(x) is $g(x)=3(x-2)^2-5~~~~~~~~~~~~~~~~~~~~~~(i)$

We know that if the vertex form of a function f(x) is written as

$f(x)=a(x-h)^2+k,$

then its vertex is (h, k).

So, from equation (i), we can say that the vertex of function g(x) is

(2, -5).

Thus, (C) is the correct option.

Solve the following system of equations using matrices (row operations).

Stells [14]

Answer:

(6,3,0)

Step-by-step explanation:

Given,

x - y + 0z = 3

6x - 0y - 2z = 36

0x + 6y + 2z = 18

You have the following augmented matrix:

(1) 1 -1 0 3

(2) 6 0 -2 36

(3) 0 6 2 18

Let's (3) add to (2) and divide by 6

(1) 1 -1 0 3

(2) 1 1 0 9

(3) 0 6 2 18

Now, let's (2) add to (1) and divide by 2

(1) 1 0 0 6

(2) 1 1 0 9

(3) 0 6 2 18

Let's (3) ÷ 2

(1) 1 0 0 6

(2) 1 1 0 9

(3) 0 3 1 9

Let's (1) subtract from (2)

(1) 1 0 0 6

(2) 0 1 0 3

(3) 0 3 1 9

Finally, let's (2) multiply by 3 and subtract from (3)

(1) 1 0 0 6

(2) 0 1 0 3

(3) 0 0 1 0

Thus,

x = 6, y = 3 and z = 0

The answer is (6, 3, 0)

We have to verify the answer

6 - 3 = 3 ⇒⇒ 3 = 3

6*6 - 5*0 = 36 ⇒⇒ 36 = 36

6*3 + 2*0 = 18 ⇒⇒ 18 = 18

What is 2/5 divided by 8/15

DochEvi [55]

3/4 is the correct answer.
<span>
This is a division problem, so we need to flip the second fraction. Then we need to multiply the numerator and denominator of the fractions to get the quotient.

</span>When we divide fractions, we have to switch the numerator and denominator of the second fraction. Now our second fraction is 15/8<span>.
</span>
<span>Multiply the numerators together, and multiply the denominators together.
</span>

The fraction 30/40 is not in lowest terms, so we need to reduce it. List the factors of the numerator and denominator:

Factors of <span>30: 1, 2, 3, 5, 6, 10, 15, 30</span>

Factors of <span>40: 1, 2, 4, 5, 8, 10, 20, 40</span>

10 is the largest factor of both 30 and 40, so we need to divide both the numerator and denominator by 10.

Numerator: 30 ÷ 10 = 3

Denominator: 40 ÷ 10 = 4

Write the new fraction:

<span>3/4</span>
