Explanation:

Your teacher is effectively asking "are the fractions 19/8 and 5/4 equal?"

Let's assume for now that they are. So we have 19/8 = 5/4

To check if that is a true equation, let's cross multiply

19/8 = 5/4

19*4 = 8*5

76 = 40

The last equation is not true, so the first equation is also not true. The ratios are not in proportion.

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

Alternative method:

Instead of cross multiplying, we can get all the fractions to have the same denominator. The LCD (lowest common denominator) of the two given fractions is 8. Let's turn 5/4 into a fraction with 8 in the denominator.

We'll multiply top and bottom by 2 to get 5/4 turning into 10/8

Now we're asking "are 19/8 and 10/8 the same?" in which the answer is "no they are not the same". The numerators 19 and 10 are different. The fraction 19/8 is larger than 10/8. So 19/8 is larger than 5/4.

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

2nd Alternative method:

Use your calculator to see that

19/8 = 2.375

5/4 = 1.25

The decimal values should be the same if the fractions were equal, but they are not. This is a very quick way to compare two fractions.

Answer:

no

Step-by-step explanation:

because they are not equivalent to each other.

Answer:

$21.50

Step-by-step explanation:

We want to find Anthony's pay for 43 hampers.

We can multiply his pay per hamper by the number of hampers picked.

pay per hamper * hampers picked

He earns $0.50 for each hamper and he picked 43 hampers. Therefore, we can multiply $0.50 and 43 to find his pay for the day.

$0.50 * 43

$21.5 = $21.50

Anthony's total pay that day is $21.50.

Answer: your answer is going to be 1/7

Step-by-step explanation:

Answer:

x = -1/7

Step-by-step explanation:

First, combine like terms:

3 - 21x = 6

Then, isolate the variable:

-21x = 3

Then, divide -21 on both sides:

x = -3/21

Finally, simplify the fraction:

x = -1/7

Answer: 22.59 yd^3

Step-by-step explanation:

First the volume of a cuboid whose measurements are:

L = length, W = width and T = thiknes is:

V = L*W*T.

We want to calculate the volume of a shape that is:

10'' thick, 18' wide and 42' long.

This notation is:

(') = feet

('') = inches

The first step is to write our 3 numbers in the same units, then we can use that:

1 inch = 0.083 ft.

Then 10 inches are equal to:

10'' = 10*(0.083 ft) = 0.83 ft = 0.83'

Then the volume of concrete needed will be:

V = 0.83ft*18ft*42ft = 627.48 ft^3

But we want this expressed in yd^3

1ft = 0.33 yd

then

1ft^3 = (0.33 yd)^3 = 0.036 yd^3

then 627.48 ft^3 can be written as:

627.48 ft^3 = 627.48*( 0.036 yd^3) = 22.59 yd^3

Answer:

False

Step-by-step explanation:

Here is a counter example:

● f(x) = x^2

● g(x) = 3x

● (f○g)(x) = (3x)^2 = 9x^2 (1)

● (g○f)(x) = 3(x^2) = 3x^2 (2)

We can see that (1) and (2) aren't equal to each others.

The given statement is False

The following information should be considered:

[tex]f(x) = x^2\\\\g(x) = 3x\\\\(fog)(x) = (3x)^2 = 9x^2 (1)\\\\(gof)(x) = 3(x^2) = 3x^2 (2)[/tex]

based on the above calculations we can see that equation (1) and equation (2) are not equal to each other.

6 = G

7 = J

8 = B

9 = A & C

10 = H

Step-by-step explanation:

Problems a through c are asking you what the values would be at those values.

What will the value of [tex]f(x)[/tex] be at [tex]x=0[/tex]? Let's look at the graph.

It seems at [tex]x=0[/tex], [tex]f(x)=0[/tex], meaning that [tex]f(0)=0[/tex]

Let's do the same for the others.

At [tex]x=-3[/tex], [tex]f(-3)=2[/tex]

At [tex]x=2[/tex], [tex]f(2)=-4[/tex]

For the last question, it is giving us the [tex]f(x)[/tex] value and asking us which [tex]x[/tex] values would give us that.

At [tex]f(x)=3[/tex], [tex]x=-2[/tex].

*Note* this function is continuous to the right, meaning that there is another point where [tex]f(x)=3[/tex].
