Express the fractions 1/2,3/16,and 7/8 with and LCD
Alexeev081 [22]
<span>LCD is the least common multiple of the denominators of the fraction. The use of finding the LCD of a fraction is to simplify the adding, subtracting, dividing and multiplying the fractions.  For ½, 2 is the least common denominator. For 3/16, 16 is the least common denominator. For 7/8, 8 is the least common denominator. Each of these fractions cannot be reduced to a simpler form because these are their simpler forms. If it can be reduced, the LCD would vary.</span>

Question 3 of 10
Grace [21]

The cost to rent the space with measures 18 ft x 16 ft for a year is $62,208

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

The area of the space = 18 ft * 16 ft = 288 ft²

The cost per month is $18 per ft² per month, hence:

The cost of rent per year = $18 per ft² per month * 288 ft² * 12 month = $62,208

The cost to rent the space with measures 18 ft x 16 ft for a year is $62,208

What is the square root of 102 approximated to the nearest tenth
alexandr1967 [171]
√102 = 10.09950494.....

So 10.09950494..... to the nearest tenth would be 10.10, because 9 comes AFTER 5 so we will go to the next number which would make the number 10.10.

SO, √102 ≈ 10.10.

Hope I helped ya!!!☺☺☺☺

Consider the graph above. Write about a situation that could be modeled using this graph. In your response, use the prompts belo
Vikentia [17]

Answer:

See Explanation

Step-by-step explanation:

Given

See attachment for graph

Required

A situation that can be modeled by the graph.

The prompt and the response are as follows:

<u>The type of function:</u>

It is a linear function

<u>The variables modeled in the function</u>

The variables are x and y

<u>The domain and the range</u>

From the graph, we can see that x and y values are not limited to any constraints.

So, the domain and the range are:

Domain: \{-\infty \le x \le \infty \}

Range: \{-\infty \le y \le \infty \}

<u>Question that could be </u>answered<u></u>

The graph could be used to predict y value, given the x value.

Take for instance, find y when x = 10

The answer can be handpicked directly from the graph. However, the best way is to calculate the graph equation, first.

So, we have:

Pick any two points on the line of the graph

(x_1,y_1) = (-2,0)

(x_2,y_2) = (0,4)

Calculate the slope (m)

m = \frac{y_2 - y_1}{x_2 - x_1}

m = \frac{4 - 0}{0 - -2}

m = \frac{4}{2}

m =2

The equation of the graph is:

y = m(x - x_1) + y_1\\

So, we have:

y = 2(x - -2) + 0

y = 2(x +2)

Expand

y = 2x +4

To solve for y when x = 10;

y = 2 * 10 +4

y = 20 +4

y = 24
