Answer:

60 minutes to fold 120 boxes

Step-by-step explanation:

easy, simply divide 40 by 2 then multiply it by 3 because this will mean hes folded 120 boxes...

40 divided by 2 is 20 times 3 is 60

80 divided by 2 is 40 times 3 is 120.

Answer:

3200

Step-by-step explanation:

you will multiply 80 by 40

80×40=3200

Answer:

2x squared - 8

Step-by-step explanation:

For this kind of equation, we use the distributive property

So in the image below I used a box method (that's how I learned it in school)

So since -4x and 4x cancel each other out, or amount to 0, we don't put anything for those. So the equation left is 2x squared - 8

Answer:

x=30° y=4

Step-by-step explanation:

[tex] \frac{y}{8} = \frac{2.5}{5} [/tex]

cross multiple

5y=8(2.5)

5y=20

divide 5 by 20

and you should y=4

since the polygons are similar x should have the same degrees as the bigger polygon

Answer: Y=4

Step-by-step explanation

Since the inside of a triangle is 180 degrees the 30 degrees plus the 90 degree corner minus the total inside degree so the other corner is 60 degrees. the dialation is 62.50  percent or .625 in decimal form which makes the vareable  y equals 4 once you divide 2.5 by .625

Given:

There are 19 oak trees in a park.

There will be 56 oak trees in the park the plantation.

To find:

How many oak trees did they plant today?

Solution:

We have,

Initial number of oak trees = 19

Number of trees after plantation = 56

Now, the number of oak trees they plant today is

New trees = Number of trees after plantation - Initial number of oak trees

                 = 56 - 19

                  = 37

Therefore, they did plant 37 oak trees today.

697.2

Step-by-step explanation:

Answer:

693 or 714 is an option

Step-by-step explanation:

693 is 33.0 x 21 = 693

714 is 34.0 x 21 = 714

Answer:

You are given a right triangle. The sum of the two acute angles should add up to 90 degrees. Set up an equation using the expressions given and solve for x. Once you know the value of x plug it back into each expression to find the measure for each angle.

Step-by-step explanation:

Angle 1 + angle 2 = 90

solve for x = ____

Plug the value into each expression to find the measure of each angle.

Answer:

D

Step-by-step explanation:

(2x+6)+(5x+14)=90

7x+20=90

7x=70

x=10

(2x+6)=26°

(5x+14)=64°

Answer:

x = -2

Step-by-step explanation:

Answer:

x=−2

Step-by-step explanation:

Let's solve your equation step-by-step.

3x+11=5

Step 1: Subtract 11 from both sides.

3x+11−11=5−11

3x=−6

Step 2: Divide both sides by 3.

3x/3=−6/3

x=−2

Answer:

C

Step-by-step explanation:

The surface area of a cylinder is given by the formula:

[tex]SA=2\pi rh+2\pi r^2[/tex]

Where h is the height and r is the radius of the cylinder.

The given radius is 6 and the height is 24.

We are also using 3.14 for π.

Therefore;

[tex]SA\approx 2(3.14)(6)(24)+2(3.14)(6)^2[/tex]

Evaluate:

[tex]SA\approx1130.4\approx 1130[/tex]

The answer is C.

Answer:

$240

Step-by-step explanation:

I = prt

I = (2,400) (0.04) (2.5)  

note: I changed 4% to a decimal and 30 months to 2.5 years

I = 96 (2.5)

I = 240   <-- The interest

------------------------------------------------------------------------------------------------------------

The simple interest accumulated on a principal of $ 2,400.00  at a rate of 4% per year for 2.5 years (30 months) is $240.00.

---------------------------------------------------------------------------------------------------------

* Last time I did interest was in 6th grade and I don't remember much. So I am very sorry if my answer is wrong *

Answer:

the answer is 12 because it sythsizes from the other part of the problem

Step-by-step explanation:

Answer:

x < 3

Step-by-step explanation:

−4x − 8 > −20

Add 8 to both sides.

-4x > -12

Divide both sides by -4. Remember that when you multiply or divide both sides of an inequality by a negative number, the direction of the inequality sign changes.

-4x/(-4) < -12/(-4)

x < 3
