Arturiano [62]

Staement 1 and statement 4 are true

Staement 1: It is incorrect because thirds and eighths cannot be divided to make ninths

Statement 4: It is incorrect because a quotient cannot be greater than the number that is divided.

<h3><u>Solution:</u></h3>

Given that, Eli evaluated 23 ÷ 38 and got an answer of 179.

Now, let us check the given statements

1) It is incorrect because thirds and eighths cannot be divided to make ninths

It seems right because when 3 is divided by 8, it will give an fractional value. So this statement is correct

2) It is correct because 38 of 23 is 179

It is wrong as 38 x 23 ≠ 179 and not even related to the question.

3) It is correct because 179 • 38 equals 23

It is wrong because 179 x 38 ≠ 23

4) It is incorrect because a quotient cannot be greater than the number that is divided.

It is right as the dividend can not be smaller than the quotient.

Hence, the 1st and 4th statements are right.

If you were to write the equation of this line in the form y=mx+c what is the value of m

marusya05 [52]

Answer:

B choice.

Step-by-step explanation:

The graph decreases. Therefore, the slope is in negative. We can rule out A and C choices.

It is very obvious to tell because of steepness. Low steepness = low value

High steepness = high value.

We can also find the slope by using rise/run.

$m = \frac{dy}{dx}$

The change of y over the change of x.

Given the coordinate points (0,1) and (4,0). Both points are part of the graph.

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

$m = \frac{1 - 0}{0 - 4} \\ m = \frac{1}{ - 4} \\ m = - \frac{1}{4}$

Therefore the value of m is - 1/4

Firdaus measured the length of the wall and got 9 feet her cousin measured the same distance and said that it was three what uni

Dahasolnce [82]

Answer:

Her cousin used Yard to measure the wall.

Step-by-step explanation:

Firdaus measured the length of the wall and got 9 feet.

Her cousin measured the same distance and said that it was 3.

To find the answer, we have to use division.

Let "x" the divisor which divide 9 and gives the answer 3.

9 ÷ x = 3

3x = 9

To find x (divisor) we need to divide both sides by 3, we get

3x ÷ 3 = 9 ÷ 3

x = 3

So 1 unit cousin's measure = 3 feet Firdaus measure

We know that 1 yard = 3 feet.

Therefore, her cousin used Yard measure to measure the wall.

You invest in a new technology company. The cost includes an overhead of $30,000, p production costs of $2500 per item produced.

Artyom0805 [142]

Answer:

A. C(x) = 30.000 + 2500x

B. R(x) = 3125x

C. 48 items break even point

Step-by-step explanation:

A. The cost function C(x) is fixed cost plus variable cost.

In this case overhead works as fixed cost, we can write:

C(x) = 30.000 + 2500x

B. Revenue R(x) would be the price multiplied by quantity of items (x).

R(x) = 3125x

C. Break even point

To get the break even point we set R(x) = C(x) and find the value of x.

R(x) = C(x)

3125x = 30.000 + 2500x

3125x-2500x=30.000

625x=30.000

x=30.000/625

x=48

It means when you sell 48 items the costs will even revenue. So if you sell more than 48, then it's going to be profitable. If you sell less than 48, you will be losing money.

HELP<br> What is the measure of an exterior angle of a regular 45-gon?

tresset_1 [31]

Answer:Sum of exterior angle of any polygon is 360o . As each exterior angle is 45o , number of angles or sides of the polygon is 360o45o=8 . Further as each exterior angle is 45o , each interior angle is 180o−45o=135o .

Step-by-step explanation: hope this helps ;)
