Answer: 1.) The slope of the longer ramp is 1/12

2.) The longer ramp from the ground to the landing is steeper. 1/12 is steeper than 1/18. A graph of the slope shows this. See attachment.

3.) If you know the run, you can find the rise by multiplying the run by the slope.

4.) The rise from the landing to the door is 1/2 foot or 6 inches.

5.) The total height of the door above the ground is 2 ft or 24 inches.

Step-by-step explanation: Sometimes it helps to draw a sketch of the info given then make notes as you find solutions. (See in attachments)

1.) 1:5/18. Multiply by 2/2. It becomes 3/36. simplify to 1/12

4.) Multiplying 9ft by 1/18

It's the same as dividing 9÷18= 0.5 ft. OR  9 feet is 108 inches. 108÷18 = 6 inches

5.) Given height, ground to landing: 1.5 ft plus calculated  0.5ft = 2 ft.

OR 18 inches + 6 inches = 24 inches

If m 2 n, which inequalities must be true? Check all that apply.
anzhelika [568]

Answer:

(a)\ m+ 2.1 > n + 2.1

(b).\ m - (-4) > n - (-4)

(c)\ 9 +m> 6 + n

Step-by-step explanation:

Given

m > n

Required

Select true inequalities

(a)\ m+ 2.1 > n + 2.1

Subtract 2.1 from both sides

m > n

This is true

(b).\ m - (-4) > n - (-4)

Open brackets

m + 4 > n + 4

Subtract 4 from both sides

m > n

(c)\ 9 +m> 6 + n

m> -9+6 + n

m> n-3

This is also true

What is the nearest tenth of .8215?
riadik2000 [5.3K]

Answer:

The answer to this would be .8

A circle has a radius of 7 inches what is the area
Scrat [10]

Answer:

49π and 153.86 when multiplyed by 3.14.

Step-by-step explanation:

Hi!

The formula for finding the area of a circle is πr².

In that case, all we have to do is substitute 7 inches for our r.

7² × π

= 49π

If you want that solved out, we can substitute a rational number for π (3.14)

49 × 3.14 = 153.86

Thus, the area of the circle is \boxed{49\pi}, 153.86 roughly.

Hope this helps!
