Answer:

13.5 meters

Step-by-step explanation:

As the rectangle has 4 sides and the length is three times the width, each pair of a long side and a short side has a perimeter of 18 meters. As the ratio is 3:1, there are 4 parts in 18 meters, and 18 divided by 4=4.5. As the length covers 3 parts, and there are 4.5 meters per part, 4.5x3=13.5. The length of the rectangle is 13.5 meters. Hope it helps!

Answer:

2^4

2 * 2 * 2 * 2

Step-by-step explanation:

In the question above :

Write an exponential expression:

Base = number between 0 and 10

Exponent = number different from the base between 0 and 10

Let base = 2

Let exponent = 4

Hence, exponential expression will be

Base^exponent

2^4 (standard form)

Expanded form:

2 * 2 * 2 * 2 (multiply 2 in 4 places)

Answer: 5

Step-by-step explanation:

I got it right on the test.

The slope of the function is 5.

The correct option is C.

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the

change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx where, m is the slope

We can take two points from the table as (-4, -16) and (-2, -6).

So, slope of the function is

= (-6 - (-16))/ (-2 - (-4))

= (-6 + 16)/ (-2 +4)

= 10 /2

= 5

Thus, the required slope is 5.

.842105263

Change to percent form

84.2105263 % decrease

Step-by-step explanation:

let x be the price of the adult ticket and y the price of child ticket

so

3x+7y=132

4x+7y=141

from the first equation 7y=132-3x

lets replaxe this from the second equation

4x+(132-3x)=141

4x-3x=141-132

x=9

so knowing that 7y=132-3x

7y=132-3*9

7y=105

y=105/7=15

so finaly the adult ticket cost 9 dollars and child ticket cost 15 dollars

#SPJ2

Answer:

First you have to split the cost of the meal and percentage so

$78.00 divided by 4 that's $19.50 each then after the 20% each would pay $23.40

Each person pay $23.4.

Given, from the fig the total cost of lunch without tip is $78.

Now, Jaime’s older brother and his three friends want to split the cost of lunch between them. So there is total 4 person.

Now each person have to pay [tex]\frac{78}{4} = $ 19.5[/tex]  dollars.

Further they decided to pay tip say 20% so, the amount of tip is 20% of $78.

On calculating amount of tip [tex]=\frac{20}{100} \times 78=15.6[/tex].

Tip is divided among them so per person has to pay tip [tex]=\frac{15.6}{4} =3.9[/tex] dollars.

So, the total amount each person has to pay [tex]=19.5+3.9=23.4[/tex] dollars.

Hence each person pay $23.4.

Answer:

It will take 4 hours for the temperatures to be the same. The temperature will be 3° at that time.

Step-by-step explanation:

Coldspot = -7 + 2.5x

Frostberg = 19 - 4x

First, we are going to input our values into the variable in a table.

          Coldspot                            Frostberg

1     -7 + 2.5(1) = -4.5                    19 - 4(1) = 15

2     -7 + 2.5(2) = -2                     19 - 4(2) = 11

3     -7 + 2.5(3) = 0.5                   19 - 4(3) = 7

4     -7 + 2.5(4) = 3                      19 - 4(4) = 3

It will take 4 hours for the temperatures to be the same. The temperature will be 3° at that time.
