How to I solve this Area Problem for 7th grade?

Answer:

  8.5 ft

Step-by-step explanation:

We assume that Mr. Simpson can model his construction using a right triangle with leg 7 ft and hypotenuse 11 ft, as shown in the attachment. Then the other leg can be found using the Pythagorean theorem.

__

  a² +b² = c²

  x² +7² = 11²

  x² = 121 -49 = 72

  x = √72 = 6√2 ≈ 8.485 . . . . feet

The slide will be set about 8.5 feet away from the base.

Answer:

6 square units

Step-by-step explanation:

The area of the base of the triangle is [tex]\sqrt{2^2+2^2}[/tex] which is [tex]2\sqrt{2}[/tex]. The height of the triangle is [tex]\sqrt{3^2+3^2}[/tex] or [tex]3\sqrt{2}[/tex]. The area of the triangle is [tex]\frac{3\sqrt{2} * 2\sqrt{2}}{2}[/tex] which is 6.

Answer:

x=-5

Step-by-step explanation:

i did 3*x and you get 3x then i did 3*5 and got 15 which now your equation will look like 3x-15=6x then you subtract the 3 with the 6 and you get -15=3x and then you divide the 3 with the -15 and get -5

Hope it helps<33

Answer:

[tex]x = -5[/tex]

Step-by-step explanation:

Step 1:  Distribute

[tex]3(x - 5) = 6x[/tex]

[tex](3 * x) + (3 * -5) = 6x[/tex]

[tex]3x - 15 = 6x[/tex]

Step 2:  Subtract 3x from both sides

[tex]-15 + 3x - 3x = 6x - 3x[/tex]

[tex]-15 = 3x[/tex]

Step 3:  Divide both sides by 3

[tex]-15/3 = 3x/3[/tex]

[tex]-5 = x[/tex]

Answer:  [tex]x = -5[/tex]

Answer:

9 inches

Step-by-step explanation:

you have to be at least 48 inches so the shortest person that can ride it is 48 and she is 39 so you minus the 39 from 48 and you will get the inches she needs to grow

Answer:

[tex]y = 2(x + 3) ^{2} - 1[/tex]

should be it. good luck!

Answer: y = 2 (x+3)^(2) -1

Step-by-step explanation:

y=mx+b formula

inside parentheses as (x+n) or (x-n) brings the graphed line left or right on the x-axis (+ is left, - is right). thus, we have (x+3), which is then squared to create the u shaped curve.

to bring the point curve to a -1 in the y-axis (-3,-1), a -1 is added to the end, outside of the parentheses. thus we now have [(x+3)^2] -1

to narrow the curve, the part parentheses is multiplied, here by two. thus, the final answer is y=[(x+3)^2]-1

Answer:

The temperature could decrease by 20˚ or increase by 20˚

Step-by-step explanation:

x-20 OR x+20

Answer:

It was 88°F hotter in Stockton.

If it was 0°F in New York, Stockton would have been greater by 83°F; as it is -5, add 5 to 83.
As the problem is subtraction, negative.
If the quantity is in negative, like -5, -7, -120; you have to add.

Answer:

8 pounds

Step-by-step explanation:

As you know from Part A, 0.5 pounds is one dollar. You want to know how many pounds cost $4. You can fill in the first and second blanks with this information.

$4 ÷ 0.5 pounds per dollar = __ pounds

4 ÷ 0.5 = 8

I hope this helps and please mark me as brainliest!

Answer:

Correct me if I am wrong but I believe the answer is:
$4 ÷ 0.5 pounds per dollar = 8 pounds

Step-by-step explanation:

Verticle angles are when two lines cross eachother or touch

Answer:

A. ∠G ≅ ∠L   AND  B. ∠Q ≅ ∠V

Step-by-step explanation:

This is because the others although they are both initially opposite and seen as vertical they have a secondary line that alters the angle and so the last two angles that have this are not vertical

Answer:

1. 2.3×10⁴

2. 2.5×10⁴

3. 0.000354

Answer:

x is to the side y is up  so you´d put A on 4 side 9 up

Step-by-step explanation:

Answer:

110.5 inches

Step-by-step explanation:

A=(a+b)/2 h

A = (8+9)/2 * 13

A = 17/2 * 13

A = 110.5 inches

Answer:

When two parallel lines are cut by a transversal, four interior angles are formed on the inside of the parallel lines and four exterior angles are formed on the outside of the parallel lines. The angles inside a polygon are called interior angles of the polygon.

Answer:

1st box: 385 in squared x .03 = $11.55 per box.

$11.55 x 50 boxes = $577.50

2nd box: 439.75 in squared x .03 = $13.1925

$13.1925 x 50 boxes = about $659.63

The company would save $659.63 - $577.50= $82.13 per 50 boxes if they go with the smaller box.

Hope this helps :)

Answer: [tex]6\frac{7}{12}[/tex]

Step-by-step explanation:

[tex]\frac{34}{12} + \frac{45}{12} = \frac{79}{12}[/tex]

[tex]\frac{79}{12} = 6\frac{7}{12}[/tex]

Answer: The answer to the equation 4,240/8 = 530

Step-by-step explanation:

4,240 divided by 8 = 530

4,000 divided by 8 = 500

4,800 divided by 8 = 600

(For part B 500 would be an underestimate of the answer to 4,240/8 and 600 would be an overestimate of 4,240/8)
