Question:- Given cube of one side 4m

=> a = 4

To find :- Surface area of cube

Answer:-

Using the formula of surface area of cube,

[tex]6 {a}^{2}[/tex]= Surface Area of cube

[tex] = > 6 \times {4}^{2}[/tex]= Surface Area

[tex] = > 6 \times 16[/tex]= Surface Area

[tex] = > 96 {m}^{3}[/tex]= Surface Area

Therefore, surface area of given cube is

Answer:

The cost of 3 lessons would be $70, and Marlowe can have 4 lessons without exceeding $100.

Step-by-step explanation:

Number of Lessons & Costs

0- 10

2- 50

4- 90

6.- 130

The equation for this would be y = 20x + 10

To find the price for 3 lessons, plug 3 as x in the equation

y = 20(3) + 10 = 70

The cost for 3 lessons would be $70

20(4) + 10 = 90

20(5) + 10 = 110

5 lessons would be $10 over. With $100, Marlowe will be able to have 10 lessons with $10 left.
P.S., Sorry I can't graph it too, and sorry I didn't respond as  quickly as I would.

Answer:

532.12

Step-by-step explanation:

251 x 2 = 502

502 x .06 = 30.12

30.12 + 502 = 532.12

Her regular fare will be $15.06.

What is mean by Percentage?

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

Given that;

The $251 includes a 6% tax on the regular fare.

Now,

Since, The $251 includes a 6% tax on the regular fare.

Hence, The regular fare = 6% of $251

                                      = 6/100 × 251

                                      = $15.06

Thus, Her regular fare will be $15.06.

Answer:

3 cups of flour.

Step-by-step explanation:

For 3 dozens of muffins we use 2.25 cups of flour. To find out how much flour we need for 4 dozens of muffins, we first need to know how much flour we need for 1 dozen of muffins.

3 dozens of muffins = 2.25 cups of flour

3/3 dozens of muffins = 2.25/3 cups of flour

1 dozen of muffins = 0.75 cups of flour.

Now that we know how much flour we need for one dozen of muffins, we can multiply it by 4 and get our answer.

1*4 dozens of muffins = 0.75*4 cups of flour

4 dozens of muffins = 3 cups of flour.

Hope this helps.

Answer:

3 cups of flour

Step-by-step explanation:

2.25/3 = 0.75
so one dozen muffins need 0.75 cups of flour

0.75 * 4 = 3

so 4 dozen muffins need 3 cups of flour

Answer:

$195.30

Step-by-step explanation:

8.5% of $150 = 85/1000 x 150

= 17/200 x150

= 17 x 3 / 4

= 51 / 4

= $12.75

Bill after tax = 12.75 + 150 = $162.75

20% of 162.75 = 1/5 x 162.75

= $32.55

Bill after tax and tips = 162.75 + 32.55 = $195.30

BRAINLIEST?

YEP, THAT'S IT.

Answer:

195.3 $

Step-by-step explanation:

In oder to find tax

     ( 150 ×8.5)÷100 = 12.75

In ordrr find tip

   ( 150 × 20) ÷ 100 = 32.55

So now add up

 150 + 12.75 +32.55 = 195.3

Answer:

Step-by-step explanation:

b + t = 15, 2b + 3t = 45

If you need it solve:

2(b + t) = 2(15)

2b + 2t = 30  Now subtract this from the second equation

 2b + 3t = 45

- 2b + 2t = 30

t = 15

Answer:

y = (x-5)²+7

Step-by-step explanation:

i graphed x²-10x+32 and found the vertex is at (5,7)

i used the y-intercept as a point on the curve in the formula:

y = a(x-h)²+k

32 = a(0-5)²+7

subtract 7 from each side to get:

25 = 5²a

25 = 25a

a = 1

y = (h-5)² + 7

x-3y=7 and 4x+2y=14

x=7+3y

using substitution method.

substitude x=7+3y in 4x+2y+=14

4(7+3y)+2y=14

28+12y+2y=14

28+14y=14

14y=14-28

14y=-14

y=-14÷14

y=-1

x=7+3y

x=7+3(-1)

x=7-3

Answer:

Step-by-step explanation:

Your first equation is y=10x+20

Your slope is 10 and your y-intercept is 20 in this first equation

Your second equation after it has changed, your new equation is y=30x+45

Your slope is 30 and your y-intercept is 45 in this second equation

I hope this helps!

The equation of line is y = 30x + 45 , where x is the number of hours

The slope of the line = 30

The y intercept of the line = 45

What is an Equation of a line?

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the equation of line be represented as A

Now , the value of A is

Let the initial amount of charge for the stable be = $ 45

Let the amount per hour for the stable be = $ 30

Let the total number of hours be = x

Now , the total amount for the stable in x hours = initial amount of charge for the stable + ( total number of hours x amount per hour for the stable )

Substituting the values in the equation , we get

y = 30x + 45

The equation is of the form y = mx + b , where m is the slope and b is the y intercept

Therefore, the value of A is y = 30x + 45

Hence , the equation of line is y = 30x + 45
