Answer

Find out the The numerical value of A - B  and the numerical value of B - A .

To prove

As given

The expression 113.47 - (43.72 - 26.9) represents A.

The expression 113.47 - (26.9 - 43.72) represents B .

Thus

A - B =  113.47 - (43.72 - 26.9)  - ( 113.47 - (26.9 - 43.72))

First solving the bracket terms.

A - B =  113.47 - (43.72 - 26.9)  -  113.47  + (26.9 - 43.72)

        = 113.47 - 16.82 - 113.47 - 16.82

        =  113.47  - 113.47 - 16.82 - 16.82

        = -33.64

Therefore the value of A- B is -33.64 .

Thus

B - A = 113.47 - (26.9 - 43.72) - (113.47 - (43.72 - 26.9))

First solving the bracket terms.

B - A = 113.47 - (26.9 - 43.72) - 113.47 + (43.72 - 26.9)

        =  113.47 + 16.82 - 113.47 + 16.82

        = 33.64

Therefore the value of the A - B is -33.64 and B - A is 33.64 .

We are given with two expressions: (A) is 113.47 - (43.72 - 26.9) and (B) is 113.47 - (26.9 - 43.72). The numerical value of A-B is 113.47 - (43.72 - 26.9)- [<span>113.47 - (26.9 - 43.72)] equal to -87.44 + 53.8 or -33.64. When B- A is to be computed, this is equal to the negative of A-B or equal to 33.64. We just have to be careful with the signs.</span>

A rocket is launched into the air. The height h(t), in yards, of the rocket is a function of time, t, in seconds, as shown in th
Vesna [10]

Answer:

Step-by-step explanation:

Average rate of change is the same thing as the slope.  Because this is parabolic, we cannot find the exact rate of change as we could if this were a linear function.  But we can use the same idea.  When t = 3, h(t) = 33, so the coordinate point is (3, 33).  When t = 6, h(t) = 0, so the coordinate is (6, 0).  Plug those values into the slope formula:

m=\frac{0-33}{6-3} and

m=\frac{-33}{3} which is -11

From 3 to 6 seconds, the rocket is falling 11 yards per second.

What is an estimation of 492.6 divided by 48
denpristay [2]
492.6/48 ~ To simply view this:

480/48 = 10
12.6/48 = 0.25 (roughly).
10.25 would roughly be your answer.

Though...
The actual answer is that:
12.6/48 = 0.2625
So... the answer: 10.2625 would be the answer.
Depending on where you have to estimate to:
10.2625
10.263
10.26
10.3

I hope that helps, have a great of your day! ^ ^

Find the values of x and y
pantera1 [17]

Answer:

x = 15°

y = 59°

Step-by-step explanation:

Angles at a right angle add up to 90°

41 + y = 90

y = 90 - 41

y = 59°

Angles in a triangle add up to 180°

41 + (2x - 9) + 7x + 13 = 180

41 + 13 - 9 + 2x + 7x = 180

45 + 9x = 180

9x = 180 - 45

9x = 135

x = 135/9

x = 15°
