Answer:

1) x = 14

2) x = 25

Step-by-step explanation:

1)

3x - 2 + 50 = 90

3x + 48 = 90

3x = 42

x = 14

2)

4x + 2 + 78 = 180

4x + 80 = 180

4x = 100

x = 25

Answer:

A.The value of a car depreciating 6% each year.

Step-by-step explanation:

According to definitions.net "The exponential function is used to model a relationship in which a constant change in the independent variable gives the same proportional change in the dependent variable."

Given that the car depereciate by 6% each year, I can write;

Let the initial value of the car be P

Let the value of the car at time t be Y

Let the number of years be t

This is a case of exponential decay so;

Y = P( 1 - 6/100)^t

Answer:

3x - y = 22

Step-by-step explanation:

The abcisssa is known as the x coordinate while the ordinate is the y coordinate

abcissa = x

ordinate = y

“three times the abscissa = 3x

“three times the abscissa decreased by ordinate is expressed as;

3x - y

Is the result is 22, hence;

3x - y = 22

this gives the required expression

y = 2x

Answer:

Cream = 3 cups

Chocolate = 6 cups

Step-by-step explanation:

Cream = 1 cup

Chocolate = 2 cups

Total = 3 cups

Cream : chocolate = 1 : 2

He uses 9 cups of these two ingredients. How many cups of chocolate does he use in this candy recipe?

Cream = ratio of cream/total ratio of total cups

= 1/3 of 9

= 1/3 × 9

= 3 cups

Cream = 3 cups

Chocolate = ratio of chocolate/total ratio of total cups

= 2/3 of 9

= 2/3 × 9

= 6 cups

Chocolate = 6 cups

Answer:

1004.8^3

Step-by-step explanation:

to find the volume you must first get the area of the base

3.14 x 8 squared or 8^2 which will equal 200.96

then you multiply the base times height

200.96^2 x 5 = 1004.8 cubed or 1004.8^3

also be careful you don't multiply 200.96 twice because it is squared (;

Answer:

4 dollars, $4

Step-by-step explanation:

As for the cost being on the side and the amount of bag tags being on the bottom, thats the first step, to study the cost to tag ratio.

1st dot: 8:2

2nd dot: 4:16

3rd dot: 24:8

Now, simply divide 8 from 2, you get 4.

Divide 4 from 16, you get 4

Lastly, divide 24 from 8 and you get 4.

That all rounds up to a integer 4 :}

Hope it helps!!

Answer:

See attachment for histogram

Step-by-step explanation:

Given

[tex]Data: 21,22.4,23,24.8,25.3,27,27.6,28.8,29.4,29.9,30.1,30.1,30.4,31.2,32,32.9[/tex]

Required

Represent on histogram

Calculate the range of the data

[tex]Range = 32.9 - 21[/tex]

[tex]Range = 11.9[/tex]

Using a width of 5, we have:

[tex]Class = \frac{Range}{5}[/tex]

[tex]Class = \frac{11.9}{5}[/tex]

[tex]Class =2.38[/tex]

Round up

[tex]Class = 3[/tex]

This means that the class will have 3 classes which are:

21.0 - 24.9, 25.0 - 29.9  and 30.0 - 34.9

The frequency table is as follows:

[tex]\begin{array}{cc}{Interval} & {Frequency}&{21.0 - 24.9} & {4} & {25.0 - 29.9} & {6} & {30.0 - 34.9} & {6} \ \end{array}[/tex]

Answer:

The y-intercept of the line is 9.

Step-by-step explanation:

y-y1=m(x-x1)

y-1=-2(x-4)

y-1=-2x+8

y=-2x+8+1

y=-2x+9

y=mx+b where m=slope and b=y-intercept
