10. Find the quotient of 3808 and 200. Write the answer as a mixed number
in simplest form.

Answers

Answer:

19.04 = 19 1/25

Hope This Helped;)

The quotient of 3808 and 200 in the form of a mixed number

in simplest form is 19 1/25.

What is an arithmetic operation?

It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that is +, -, ×, and ÷.

It is given that:

The numbers are 3808 and 200

After dividing:

= 3808 ÷ 200

Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.

Or

= 3808/200

Divide both the numerator and denominator by the GCD

= 476/25

= 19 1/25

Thus, the quotient of 3808 and 200 in the form of a mixed number

in simplest form is 19 1/25.

PLS HELP ME UNDERSTAND THIS!!

Answers

Answer:

[tex] \frac{ - (5.8 - 3(3.2))}{ {( - .2)}^{2} } + 3 \\ = \frac{ - (5.8 - 9.6)}{.04} + 3 \\ = \frac{ - ( - 3.8)}{.04} + 3 \\ = \frac{3.8}{.04} + 3 \\ = 95 + 3 \\ = 98 \\ thank \: you[/tex]

Answer:

Below

Step-by-step explanation:

First we will evaluate the brackets (BEDMAS)

      - (5.8 - 9.6) / (-0.2)^2 + 3

      - ( -3.8 ) / ( 0.04) + 3

Because there is a negative sign on both the outside and inside of a bracket, that number becomes positive

      ( 3.8 ) / ( 0.04 ) + 3

Calculate this :

      = 95 + 3

      = 98

What transformations take place by graphing the function below in respect to its parent function? Check all that apply.

Answers

Answer:

y = x² is the parent

y = 3/2(x+7)²+2 shifts 7 u left, up 2 u, and has vertical compression

Answer:

Right 7 unitsUp 2 unitsVertical Stretch

Step-by-step explanation:

Given the function, f(x) = 3/2(x + 7)² + 2,

where:

a = 3/2

vertex (h, k ) = (7, 2)

The value of a determines whether the graph opens up or down. The value of a  also makes the parent function wider or narrower (vertical stretch by a factor of a ).  If a > 1, the graph is narrower than the parent function. The value of h determines how far left or right the parent function is translated. If h is positive, the function is translated h units to the right. The value of k determines how far up or down the parent function is translated.  If k is positive, the function is translated k units up.

 

Given these descriptions, we can assume that:

The function is vertically translated  by 2 units upward. The function is horizontally translated  by 7 units to the right.Vertical stretch by a factor of 3/2 (or 1.5).

3x + 7

Step-by-step explanation:

1. A coefficient is a number that is multiplied by a variable. For example, the coefficient of 5x would be 5.

2. A constant is a fixed value; it's a number that has a value which is known and usually stands alone.

3. Given the information above, 3x + 7 has a coefficient of 3 and a constant of 7.

Therefore, the answer is 3x + 7.

Answer:

3x + 7

Step-by-step explanation:

Coeffiecients are the numbers that come before a variable. The variable in this question is x, so you should look for the choice with 3x.

Constants are numbers that are on its own in any equation.

So your answer is 3x + 7.
