Svet_ta [14]3 years ago

Answer:

Gross estimate: 1/2

Good estimate: 1/3

Exact answer: 29/88

Step-by-step explanation:

You ask for an estimate.

7/8 is close to 1

6/11 is close to 1/2

1-1/2 = 1/2

This is a gross estimate.

The exact answer is found by getting a common denominator of 88

7/8 *11/11= 77/88

6/11*8/8 = 48/88

77/88 -48/88 =29/88

This is just a little less than 1/3

Rounding our answer 29 is close to 30  and 88 is close to 90

30/90 = 1/3

Which number line best shows how to solve −8 − (−2)? A number line from negative 10 to 10 is shown, with numbers labeled at inte
LekaFEV [45]

Answer:

A number line from negative 10 to 10 is shown, with numbers labeled at intervals of 2. An arrow is shown from point 0 to negative 8. Another arrow points from negative 8 to negative 6

Step-by-step explanation:

A number line is a straight line with numbers placed at equal intervals. Positive numbers are placed to the right of 0 and negative numbers are placed to the left of zero.

When a number (x) is added x unit is moved to the right while if a number (x) is subtracted x units is moved to the left.

To solve -8 - (-2) = -8 + 2

Given a A number line from negative 10 to 10 with numbers labeled at intervals of 2. An arrow is shown from point 0 to negative 8 then since 2 is added, we move 2 units right from negative 8 to negative 6.

Can anyone solve and explain part b
rewona [7]

Answer:

Below in bold.

Step-by-step explanation:

b.

If we drop a perpendicular line from B to AC and mark the point D on AC, we have 2 right triangles, with AD = DC = 16 cm.

So tan O = BD/16 = 15/8

BD = (16*15)/8

= 2*15

= 30.

So the area of triangle ABC = 16*30

= 480 cm^2.

this graph shows the amount of rain that falls in a given amount of time. what is the slope of the line and what does it mean in
Galina-37 [17]

Answer:

-5/-2 or 2.5

Step-by-step explanation:

Because you gave two points that I'm guessing are from the graph I think that's the answer. Because when you use the slope formula y2-y1 over x2 - x1 you get -5/-2 or you either get 2.5 meaning that is the slope specifically saying the rate of change. You get 2.5 when you divide -5/-2 incase you need a decimal or want to simplfy it.
