Answer:

8 phone cells

Step-by-step explanation:

We are told that he spent 14 minutes on the phone while routing 7 phone calls.

Now, we want to find the number of phone cells he will route for a total of 16 minutes.

Thus, by proportion using unit rates;. Number of minutes spent pet phone cell = 14 minutes ÷ 7 phone calls = 2 minutes per phone cell

Therefore, for 16 minutes, number of phone cells will be;

16 minutes ÷ 2 minutes per phone cell = 8 phone cells

Answer:

The unit rate = 27 miles per gallon.

Hence, option C is true.

Step-by-step explanation:

From the given line graph:

Taking two points

The unit rate can be determined by finding the rate of change or slope between the points (2, 54) and (6, 162)

[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\left(x_1,\:y_1\right)=\left(2,\:54\right),\:\left(x_2,\:y_2\right)=\left(6,\:162\right)[/tex]

[tex]m=\frac{162-54}{6-2}[/tex]

Refine

[tex]m=27[/tex]

Therefore, the unit rate = 27 miles per gallon.

Hence, option C is true.

Answer:

Greek city-states likely developed because of the physical geography of the Mediterranean region. The landscape features rocky, mountainous land and many islands. These physical barriers caused population centers to be relatively isolated from each other. The sea was often the easiest way to move from place to place.

Answer: 262.6

Step-by-step explanation: Well if she sold 110 hamburgers on tuesday for $545 That is a simple division equation (545/110). After dividing the answer would be how much each hamburguer cost on its own ( 4.954545454545455), you would then multiply that by the number of hamburgers she sold (53) and get your answer. (262.5909090909091) I am not quite sure where she wants us to round the answer to. so I just did the tens place.

Answer:

Well they are all equal sides so it could really be anything that's an even number ranging from 10-20, hope this helped and good luck on your test! :D

Answer:

[tex]x=9, AB=BC=AC=35[/tex]

Step-by-step explanation:

Equilateral triangles have 3 congruent sides, so all 3 sides have the same length. Therefore, we know that [tex]AB=BC=AC[/tex]. We are given the lengths of all 3 sides in terms of [tex]x[/tex], but we only need to set two of them equal to each other to solve for [tex]x[/tex]. Let's use [tex]AB[/tex] and [tex]BC[/tex] to solve for [tex]x[/tex]. We know that [tex]AB=BC[/tex], [tex]AB=2x+17[/tex], and [tex]BC=6x-19[/tex]. Therefore, we can write the following equation to solve for

[tex]AB=BC\\2x+17=6x-19[/tex] (Substitute given values into equation)

Solving for [tex]x[/tex], we get:

[tex]2x+17=6x-19\\2x+17-17=6x-19-17[/tex] (Subtract [tex]17[/tex] from both sides of the equation to isolate constants)

[tex]2x=6x-36[/tex] (Simplify)

[tex]2x-6x=6x-36-6x[/tex] (Subtract [tex]6x[/tex] from both sides of the equation to isolate [tex]x[/tex])

[tex]-4x=-36[/tex] (Simplify)

[tex]\frac{-4x}{-4}=\frac{-36}{-4}[/tex] (Divide both sides of the equation by [tex]-4[/tex] to get rid of [tex]x[/tex]'s coefficient)

[tex]x=9[/tex] (Simplify)

Therefore, [tex]AB=2x+17=2*9+17=18+17=35[/tex], and [tex]AB=BC=AC=35[/tex]. Hope this helps!

Step-by-step explanation:

one negative* one negative = always positive

Answer:

Step-by-step explanation:

[tex]24a-3(2a-5)=51[/tex]

Step 1: Let's solve first so we can order  it later.

[tex]24a-6a+15=51\\18a+15=51\\-15 -15\\\18a=36\\\\[/tex]

Divide 18 both sides.

[tex]a=2[/tex]

Ok so we have everything solved answer: a=2.

Now we need to order.

Step 1. Distribute 3.

Step 2. Combine like terms 24a and 6a.

Step 3. Subtract 15 from both sides.

Step 4. Divide both sides by 18.

Hope this helps :)

Answer:

The coordinates of the other point are:

(x₂, y₂) = (18, 20)

Hence, option A is correct.

Step-by-step explanation:

Given

To determine

Using the Mid-point formula between (x₁, y₁) and (x₂, y₂)

[tex]\left(x,\:y\right)=\:\left(\frac{x_2+x_1}{2},\:\:\frac{y_2+y_1}{2}\right)[/tex]

Here:

(x, y) is the midpoint between (x₁, y₁) and (x₂, y₂)

substituting (x, y) = (0, 5) and (x₁, y₁) = (-18, -10) in the formula

[tex]\left(0,\:5\right)=\:\left(\frac{x_2+\left(-18\right)}{2},\:\:\frac{y_2+\left(-10\right)}{2}\right)[/tex]

equating

[tex]0=\frac{x_2+\left(-18\right)}{2}[/tex]

[tex]x_2-18=0[/tex]

Add 18 to both sides

[tex]x_2-18+18=0+18[/tex]

[tex]x_2=18[/tex]

also

[tex]5=\frac{y_2+\left(-10\right)}{2}[/tex]

[tex]10=y_2+\left(-10\right)[/tex]

[tex]10=y_2-10[/tex]

[tex]10+10=y_2[/tex]

[tex]10+10=y_2[/tex]

[tex]y_2=20[/tex]

Therefore, the coordinates of the other point are:

(x₂, y₂) = (18, 20)

Hence, option A is correct.

Answer:

(x₂, y₂) = (18, 20)

Answer:

no it not

Step-by-step explanation:

X = y2 would be a sideways parabola and therefore not a function. ... If a vertical line passes thru two points on the graph of a relation, it is NOT a function

The total amount of income Xander earns from selling y books algebraically is C = 25000 + xy + 0.08y.

An equation is the statement that illustrates the variables given. In this case, two or more components are taken into consideration to describe the scenarios.

In this situation, Xander writes math textbooks that sell x dollars each, he received a bonus of $25,000 for signing a contract, and he receives 8% commission on each book sale.

c = total amount

y = number of books.

The total amount of income will be:

= 25000 + (x × y) + (8% × y)

= 25000 + xy + (0.08 × y)

C = 25000 + xy + 0.08y

Answer: -4

Step-by-step explanation:

13 - 9 = 4

9 - 5 = 4

so, we can see that it is decreasing by 4 each time.

Answer:

common difference is -4

Step-by-step explanation:

The common difference is the amount we add  between terms

13 + d = 9

Subtract 13 from each side

13+d-13 = 9-13

d = -4

Check

9+d = 5

9 + -4 = 5

5= 5

This is true so the common difference is -4
