Answer:

[tex]Height = 15[/tex]

[tex]Base = 45[/tex]

Step-by-step explanation:

Given

Shape: Rectangle

[tex]Perimeter = 120cm[/tex]

[tex]Base = 3 * Height[/tex]

Required

Determine the dimensions

The perimeter of a rectangle is:

[tex]Perimeter = 2 * (Base + Height)[/tex]

Substitute 120 for Perimeter

[tex]120 = 2 * (Base + Height)[/tex]

Divide both sides by 2

[tex]60 = Base + Height[/tex]

Substitute 3 * Height for Base

[tex]60 = 3 * Height + Height[/tex]

[tex]60 = 3Height + Height[/tex]

[tex]60 = 4Height[/tex]

Divide both sides by 4

[tex]15 = Height[/tex]

[tex]Height = 15[/tex]

Substitute 15 for Height in [tex]Base = 3 * Height[/tex]

[tex]Base = 3 * 15[/tex]

[tex]Base = 45[/tex]

Answer:

3 cantaloupes

Step-by-step explanation:

Since there are 24 students if you divide 24 by 3 it equals  8 so eat cantaloupe should be cut into 8 pieces. So, Mr.chu should buy 3 cantaloupes and cut each of the cantaloups in 8 equivalent slices for the students.

Answer:

there would be 11 accidents of people

Step-by-step explanation:

6+3+1+1= 11

or

6+3+2= 11

or

6+5 =11

Answer: It would be 2x-19

Step-by-step explanation:

Answer: B) 4.28

The 2 is in the tenths place, and 8 is to the right of it. The 8 is five or larger, so that means we bump the 2 up to 3. We erase the 8. So we go from 4.28 to 4.3; we have a 3 in the tenths place as instructed.

We can think of 4.3 as 4.30

Note how 4.28 is closer to 4.30, than it is to 4.20

Answer:

Answer = 14. 2

Step-by-step explanation:

Area of rectangle = length x breath

So, area here is = 49.7 cm2

Breath = 3.5 cm

49.7 = length x 3.5

Length = 49.7 ÷ 3.5

Length = 14.2 cm

Answer:

1.2599

Step-by-step explanation:

Answer:

Selling the total for $ 1276, Ace lost $ 1.37 for each meter.

Step-by-step explanation:

Given that Ace earned $ 176 selling 32 meters of cloth at $ 1496, to find out his loss for each meter if he sold the total for $ 1276, the following calculation must be performed:

1496 - 176 = 1320 (stock price)

1320/32 = 41.25 (price per meter)

1276/32 = 39.87

41.25 - 39.87 = 1.37

Thus, selling the total for $ 1276, Ace lost $ 1.37 for each meter.

let's find the area of the outer circle and the inside circle

the inside's circle area

A= π x 6²=36π

the outer's

A' = π x 4x²= 4πx²

A'-A=4πx²- 36π=160πcm² equivalent to x²- 9=40, so x²=49 implies x =sqrt(49)=7, x=7.

Answer:

-3x+31

Step-by-step explanation:

Ok so first let's get the negative out of the parentheses

(2x+37-4)-(5x+2) -> 2x+37-4-5x-2

Now this will make it easier to simplify the equation

2x-5x+37-4-2

All you have to do from there is simplify

-3x+31

Answer:

Monkey: -5/2

Step-by-step explanation:

monkey = x

3x + 4 = -x - 6

3x + x = -6 - 4

4x = -10

4x/4 = -10/4

x = -5/2

Check:

3x + 4 = -x - 6

3(-5/2) + 4 = -(-5/2) - 6

-15/2 + 4 = 5/2 - 6

-15/2 + 8/2 = -3.5

-7/2 = -3.5

-3.5 = -3.5

Answer:

-2.5

Step-by-step explanation: 3x+4=-1x-6

                                            +1x       +1x

                                        4x+4=-6

                                             -4  -4

                                         4x=-10

       divide                           _     _

                                           4     4      = -2.5

Answer:

The top left one is correct.

Step-by-step explanation:

We can rewrite this as an algebraic expression simply so it's easier to read.

Let's say hopscotch is [tex]h[/tex]. Tag is 6 times [tex]h[/tex], or [tex]6h[/tex].

That means for every 1 unit of hopscotch, there are 6 units of tag.

The top left one is correct.
