Round 89972 to 3 significant figures

Mathematics

kenny6666 [7]3 years ago
4 0
We round a number to three significant figures in the same way that we would round to three decimal places. We count from the first non-zero digit for three digits. We then round the last digit. We fill in any remaining places to the right of the decimal point with zeros.

Question with last attempt is displayed for your review only
Alika [10]

Answer:

43.13 = 5.25h + 9

Step-by-step explanation:

Let's solve this by making an equation.

$9 for the helmet, and $5.25 per hour.

h will stand for hours, C will stand for Amanda's cost.

C = 5.25h + 9

Now, substitute in what we learned from the problem.

43.13 = 5.25h + 9

This is an equation you can use to solve for the hours.

A rectangle on a coordinate plane has vertices Q(-1, 1), R(6,1), S(6,-8), and T(-1,-8). What are the dimensions of the rectangle
xeze [42]

Answer:

The length is 9.

The width is 7.

Step-by-step explanation:

A rectangle has two dimensions.

The width, which is the distance between the points who have the same value of y.

The length, which is the distance between the points who have the same value of x.

Distance between 2 points:

Points (a,b) and (c,d).

D = \sqrt{(c-a)^{2} + (d-b)^{2}}

Same value of x:

(-1,1), (-1-8) or (6,1), (6,-8)

The distance for both of them is the same, can calculate for only one.

L = \sqrt{(6-6)^{2} + (-8 - 1)^{2}} = \sqrt{81} = 9

The length is 9.

Same value of y:

(-1,1), (6,1) or (6,-8), (-1,-8)

W = \sqrt{(6 - (-1))^{2} + (1 - 1)^{2}} = \sqrt{49} = 7

The width is 7.

Jen ran 3/4 mile in 18 minutes at 9 am and 2 1/4 miles in 27 minutes at 6 pm. Is this proportional or non proportional?
VMariaS [17]

Answer:

It's non-proportional

Step-by-step explanation:

You could tell every 1/4 mile is 6 minutes, so every other number should be a multiple of 6 if it is a multiple of 1/4. 27 is not a multiple of 6.
