What is the percent of increase from 80 to 95?

Answer:

x = 3

Step-by-step explanation:

7(x + 4) - 7 = 48 - 2x ← distribute parenthesis and simplify left side

7x + 28 - 7 = 48 - 2x

7x + 21 = 48 - 2x ( add 2x to both sides )

9x + 21 = 48 ( subtract 21 from both sides )

9x = 27 ( divide both sides by 9 )

x = 3

Answer: the answer is x=3

Step-by-step explanation:

step 1: distribute the 7 with the parenthesis we get 7x+28-7=48-2x

step 2: subtract 28-7 which gives us 21 now the equation is 7x+21=48-2x

step 3: for the other side which is the 48-2x put the x first so the equation will look something 7x+21=-2x+48

step 4: subtract 21 on both sides 48-21=27 and add 2x on both sides 7x+2x=9x

step 5: 9x=27 now divide both sides by 9 so 27/9= 3

Answer:

21:20

Step-by-step explanation:

Since there are 20 cars with sunroof

Subtract 20 from 41

and you get 21 which are the cars with no sunroof

making it 21:20

Answer: 21 : 20

Step-by-step explanation: Since the factory made 41 cars and 20 of them had a sunroof that means x = 41 -20. So 41 - 20 = 21 cars without sunroof. They ask to put the ratio with cars without sunroof first then cars with a sunroof so it would be 21 : 20.

(x = cars without sunroof)

Answer:

The angle in C

Step-by-step explanation:

(a)

[tex]SI = \frac{PRT}{100} \\ = \frac{1800 \times 5 \times 1}{100} \\ = 18 \times 5 \\ = 90[/tex]

Total amount = SI + Amount

= 90 + 1800 = $1890

(b)

[tex]SI = \frac{PRT}{100} \\ = \frac{2600 \times 12 \times 3}{100} \\ = 26 \times 12 \times 3 \\ = 26 \times 36 \\ = 936[/tex]

Total amount = SI + Amount

= 936 + 2600 = $ 3236

(c)

[tex]SI = \frac{PRT}{100} \\ = \frac{3125 \times 15 \times 0.2}{100} \\ = 93.75[/tex]

Total amount = SI + Amount

= 93.75 + 3125 = $ 3,218.75

The simple interest on $1800 is $90.

The simple interest on $2600 is $936.

The simple interest on $3125 is $93.75

Simple interest is when interest is earned only on the amount of money deposited.

Simple interest  = amount deposited x time x year

1800 x 0.05 x 1 = $90

2600 x 0.12 x 3 = $936

3125 x 0.15 x (73/365) = $93.75

The standard form of linear equation:

Convert each equation into standard form:

Answer:

y = 3x - 7

Step-by-step explanation:

Slope - Intercept Form :  [tex]y = mx+b[/tex]

[tex]m[/tex] = slope

[tex]b[/tex] = y - intercept

Slope =  [tex]\frac{rise}{run}[/tex]

          = [tex]\frac3{1}[/tex]

          = [tex]3[/tex]

So far:   [tex]y = 3x + b[/tex]

Plug in a point from the graph, ex. (3,2)

[tex]2 = 3(3) + b\\\\2 = 9 + b\\\\b = -7[/tex]

Equation :   [tex]y = 3x - 7[/tex]

Step-by-step explanation:

Volume= pi x radius squared x height

substitiute values

540π= π x r^2 x 15

divide 540π by π and 15

so thats 36= radius squared

so the radius is 6 as 6 squared is 36

so the diameter is radius x2

so the answer is 12

She will still need about 450$

Step-by-step explanation:

So from what I have learned, she will need to work in order to get the money, but even when she is working, she may have expenses to pay and she may not make it, but she will because she can do loans and when she earns the money from loans, then she can pay, then she may have left over money she can use while on trip.
