Answer:

1.) 12 hours   2.) She made a multiplying error in the table.

Step-by-step explanation:

1.)

First, let's find the slope of this equation:

m = 135 - 81 / 5 - 3

m = 54/2

m = 27

Therefore, the equation should be y = 27x.

Now we substitute 324 for y and solve for x:

324 = 27x

12 = x (Divided 27 on both sides.)

Therefore, someone would have to work 12 hours in order to earn $324.

2.)

For this problem, it appears Amanda has found the correct equation for her recipe. When taking a look at the table, however, it seems as though she has made a multiplying error.

Given problem:

 Solve using the property of equality;

               -7 + x = 12

The properties of equality are;

     Addition. Definition. If x = y, then x + c = y + c. ...

     Subtraction. Definition. If x = y, then x – c = y – c. ...

      Multiplication. Definition. If x = y, then xc = yc. ...

     Division. Definition. If x = y and c is not equal to 0, then x / c = y / c

Now;

        - 7 + x = 12;

  base on the properties of equality, to eliminate -7, add +7 to both sides;

        -7 + 7 + x  = 12 + 7

                    x = 19

Based on the properties of equality, the solution is 19

Answer:

B. 0.90x=43

E.2(x-0.10x+2.5)=91

Step-by-step explanation:

Given equation:

   x-0.10x+2.5 = 45.5

     Let us simplify this;

Collect like terms;

         x - 0.10x = 45.5 - 2.5

Simplify;

             0.9x = 43 (Option A)

Also;

        x-0.10x+2.5 = 45.5

     Simplify by multiplying both sides by 2;

    2(x - 0.10x + 2.5) = 2(45.5)

    2(x - 0.10x + 2.5) = 91.0

Also;

      x-0.10x+2.5 = 45.5

        0.9x + 2.5 = 45.5

Those are the three scenarios

Given parameter:

Diameter of the ferris wheel  = 80m

Unknown:

Distance covered in one complete rotation = ?

Solution:

One complete rotation will sweep through the circumference of the wheel.

So,

  One complete rotation = Circumference of circle  = 2 [tex]\pi[/tex] r

Where r is the radius;

         Radius here is [tex]\frac{80}{2}[/tex]  = 40m

So circumference = 2 x [tex]\pi[/tex] x 40 = 80[tex]\pi[/tex]

The distance the wheel sweeps through will be 80π m

Answer:

4x-9=99

1. Move -9 to the side with 99 and change the sign

4x=99+9

2. Sum

4x=108

3. Divide 4x by 4 to leave the X alone. Do the same on the other side.

4x/4=108/4

4. Complete the division

x=27

Verification:

4(27)-9=99

108-9=99

99=99 (TRUE)

I think dont know

Answer:

81

Step-by-step explanation:

here,

(a+b)=15 -------(1)

(a-b)=12 -------(2)

Equating the equation (1) and (2)

a + b = 15

a - b = 12

(b gets cancelled having opposite signs)

or, 2a = 27

or, a = 27÷2

a = 13.5

then, putting value of a in equation (1)

a+b=15

or, 13.5 + b=15

or, b=15-13.5

b=1.5

lastly,

4ab = 4×13.5×1.5

= 81

hope it helps!!

Answer:

B

Step-by-step explanation:

You can rule out all others. A is wrong because a triangle cannot be acute and obtuse at the same time. C is wrong because a polygon dosen't neccassarily need to be a triangle, for example, a polygon is a closed shape, so it could be a rectangle. It isn't D because there are obtuse triangles out there. So, the only one left is B.

The answer is B because if the triangle is a polygon then the conclusion would be that it is either acute or obtuse.

Given:

Anna completes a lap in 120 minutes.

Aman completes a lap in 240 minutes

Tina completes a lap in 60 minutes.

To find:

The time after which they will meet again.

Solution:

They all started at the same time. So, the time after which they will meet again is the LCM of time taken by them to complete a lap.

Required time = LCM(120,240,60)

Factors of [tex]120 = 2\times 2\times 2\times 3\times 5[/tex]

Factors of [tex]240=2\times 2\times 2\times 2\times 3\times 5[/tex]

Factors of [tex]60=2\times 2\times 3\times 5[/tex]

So,

[tex]LCM(120,240,60)=2\times 2\times 2\times 2\times 3\times 5[/tex]

[tex]LCM(120,240,60)=240[/tex]

Therefore, after 240 minutes they will meet again.

The 2 is in the ten thousands place. There is a 3 in the thousands place. Since 3 is less than 5, 2 stays the same and everything after it turns into 0s.

20,000

Answer: 20,000

Answer:

a is 64 b 125 c 36

Step-by-step

so you do 2 times 2 times 2 = 8 because there is a 3 so you multiply it by it self how ever many times the number above it says so after you do that its the same for the other number so they are both 8 so 8 times 8 is 64

So, obviously, since one of the prices is given, which is $2.00 for the kid's meal, then you need to subtract that from his $32.00 total to know what number you need to divide into the 6 sandwiches. So, so far you have $30.00. If you divide $30.00 by the 6 sandwiches, you will find out he could only spend $5.00 per sandwich. So basically, you got the expression of (32 -2) / 6 in order to find out that your answer is $5.00. Looking at you answer choices, I can see right away that D is correct. For the inequality, I can see that B would be the correct answer for this problem because he can't go over budget. So, your answers are B and D.

Step-by-step explanation:

Let the number of toppings be y

If cheese pizza at Chicago's Deep Dish pizza costs $7 and each topping costs an additional $0.75, the total amount of the dish pizza will be expressed as;

$7 + $0.75y ..... 1

Also, if a cheese pizza at Brooklyn's cost $12 and each topping costs an additional $0.50, then the total cost of cheese pizza will be;

$12 + $0.50y ........ 2

If the two pizzas cost the same, then equation 1 will be equal to equation 2 as shown;

7+0.75y = 12+0.50y

Make y the subject of the formula to generate the required equation for y:

0.75y-0.50y = 12-7

0.25y = 5

divide both sides by 0.25

0.25y/0.25 = 5/0.25

y = 5/0.25

y = 20

Hence the equation that represents how many toppings, y, must be added so that the two pizzas cost the same is y = 5/0.25 and the number of toppings added is 20.
