Answer:
1.19
Step-by-step explanation:
1) Shift the decimals of both 0.8449 and 0.71 to the right by 2 decimal places. (This is needed to convert 0.71 to 71, since long division must divide by a whole number.)
84.49 ÷ 71
2) Use the algorithm method.
1 . 1 9
7 1 | 8 4 . 4 9
7 1 .
1 3 . 4
7 . 1
6 . 3 9
6 . 3 9
3) Therefore, 0.8449 ÷ 0.71 = 1.19.
1.19
The range is the high and low points.
So (5, 2]
Answer:
1st to 4th: Sam, Cras, Randy, Charte
Step-by-step explanation:
The places are determined by putting the times in increasing order.
<u>time</u>, <u>place</u>, <u>name</u>
25.85, 1st place, Sam
25.90, 2nd place, Cras
32.20, 3rd place, Randy
32.28, 4th place, Charte

<em>Additional comment</em>
Sometimes it is easier to compare values when they all have the same number of decimal places.
Answer:
you have the answer correct actually
Step-by-step explanation:
Answer:
the width in the original rectangle is 24 meters.
Step-by-step explanation:
We know the perimeters of both rectangles therefore we can calculate the scale in this way:
120/30 = 4
Which means that there is a 4: 1 scale between the original and the reduced rectangle.
We know that the length in the reduced rectangle is 9, therefore in the original it would be:
9 * 4 = 36
Which means that 36 meters is the length of the original rectangle. We know that the perimeter is equal to:
p = 2 * l + 2 * w
replacing:
120 = 2 * 36 + 2 * w
2 * w = 120 - 72
w = 48/2
w = 24
Which means that the width in the original rectangle is 24 meters.
