Reuben dogs 2.25 miles every weekdayOn weekends he’s jogs 1.8 times as far to the nearest hundred how many miles does reuben

77julia77 [94]

Answer:

Distance covered by Reuben jogging in 4 calendar weeks = 61.2 miles

Step-by-step explanation:

Distance covered by Reuben jogging every weekday = 2.25 miles

Distance covered by Reuben jogging every weekends is 1.8 times as far as he covers in weekdays to nearest hundred.

To find Reuben jogs in 4 calendar weeks.

Solution:

Distance covered by Reuben jogging every weekends = $1.8\times 2.25\ miles= 4.05\ miles$

There are 5 weekdays in a week.

Thus, total distance traveled in weekdays = $2.25\times 5=11.25\ miles$

Distance jogged in a week = $4.05\ miles + 11.25\ miles =15.3\ miles$

Using unitary method to find distance jogged in 4 weeks.

If Reuben jogs 15.3 miles in a week

Thus, in 4 weeks he will jog = $15.3\ miles \times 4 =61.2\ miles$

Leslie keeps her goats

Gemiola [76]

Answer:

Step-by-step explanation:

Circumference = 2 π r

100 = 2 π r

r = 100 / 2π

= 50/π

So the area = π r^2

= π * (50/π)^2

= 2500/π

= 795.8 yd^2.

How do you have all the answers to 9 divided by 248

kaheart [24]

Answer:

the answer to 248 divided by 9 is 27 remainder 5

Step-by-step explanation:

Step 1) Start by setting it up with the divisor 9 on the left side and the dividend 248 on the right side like this:

Step 2) The divisor (9) goes into the first digit of the dividend (2), 0 time(s). Therefore, put 0 on top:

Step 3) Multiply the divisor by the result in the previous step (9 x 0 = 0) and write that answer below the dividend.

Step 4) Subtract the result in the previous step from the first digit of the dividend (2 - 0 = 2) and write the answer below.

Step 5) Move down the 2nd digit of the dividend (4) like this:

Step 6) The divisor (9) goes into the bottom number (24), 2 time(s). Therefore, put 2 on top:

Step 7) Multiply the divisor by the result in the previous step (9 x 2 = 18) and write that answer at the bottom:

Step 8) Subtract the result in the previous step from the number written above it. (24 - 18 = 6) and write the answer at the bottom.

Step 9) Move down the last digit of the dividend (8) like this:

Step 10) The divisor (9) goes into the bottom number (68), 7 time(s). Therefore put 7 on top:

Step 11) Multiply the divisor by the result in the previous step (9 x 7 = 63) and write the answer at the bottom:

Step 12) Subtract the result in the previous step from the number written above it. (68 - 63 = 5) and write the answer at the bottom.
