Answer: 213/40 or 5.325

Step-by-step explanation:

We can find common denominators for 8 1/5 and 2 7/8.

The Lowest Common Denominator for 8 1/5 and 2 7/8 is 40.

8 1/5 = 41/5 = 328/40.

2 7/8 = 23/8 = 115/40.

Now we can subtract.

328/40 - 115/40 = 213/40.

Therefore, the answer is 213/40 or 5 13/40.

London's family took a road trip to the Grand Canyon. London fell asleep 61% of the way through the trip. If London fell asleep after they had travelled 305 miles, what was the total length of the trip?

Answers

Answer: 782.05 miles.

Step-by-step explanation: Percentage is a ratio expressed as fraction of 100, in other words, 61% is represented as [tex]\frac{61}{100}[/tex] or 0.61.

London slept 61% of the journey, so it means he was awake for 39% of the journey. Now the total trip is [tex]\frac{100}{100}[/tex] or 1, so the relationship will be

0.39 ---- 305 miles

1 ----- x

[tex]x=\frac{305}{0.39}[/tex]

x = 782.05

The total length of the trip was 782.05 miles.

4. David hikes 2 1/4 miles in 1/2 hour. At this rate how long will it take him to walk 1 mile? If he walks for 1 hour,
how far will he have gone? yes

Answers

Answer: 4.50 miles.

Step-by-step explanation:

David hikes 2 1/4 miles in 1/2 hour. To make it easier, we can turn the fractions into decimals.

David hikes 2.25 miles in 0.5 miles.

The ratio of miles hiked to the hours hiked is 2.25 : 0.5. For every 0.5 hours, David hikes 2.25 miles.

To find how many miles David walks in 1 hour, we should multiply the original ratio by 2. 0.5 x 2 = 1, and we need to find how far David walks in 1 hour.

If David hikes 2.25 miles in half an hour, then he will walk 4.50 miles in 1 hour. So the answer is that David will walk 4.50 miles in 1 hour.

A highway inspector needs an estimate of the mean weight of trucks crossing a bridge on the interstate highway system. she selects a random sample of 49 trucks and finds a mean of 15.8 tons with a sample standard deviation of 3.85 tons. the 90 percent confidence interval for the population mean is:

Answers

Answer:

14.90 to 16.70 tons

Step-by-step explanation:

We are given;

Sample size; n = 49

Mean; x¯ = 15.8

Sample standard deviation; s = 3.85

At 90% Confidence interval, z = 1.645

Formula for confidence interval is;

CI = x¯ ± z(s/√n)

Thus;

CI = 15.8 ± 1.645(3.85/√49)

CI = 15.8 ± 0.90

CI = 14.90 to 16.70 tons

Answers

Answer:

12.56 inches

Step-by-step explanation:

Circumference: C = 2*pi*r

I will be using 3.14 in place of pi

Divide the diameters by 2, so 3 for Zoey and 5 for Sam

Multiply (2*3.14*3) and (2*3.14*5)

For Zoey you get 18.84 and for Sam you get 31.4

31.4-18.84= 12.56 in difference

5 * 70 = 5 * (__ * 10)

We have to equal the value of 5 * 70 by inputting the missing number.

What times 10 equals 70?

5 * 70 = (5 * __) * 10

This goes for the same as the one before, what times 5 equals 5 * 70 to the same amount?

An airplane is currently flying at an altitude of 37,000 feet. The airplane is scheduled to land at an airport 100 miles

away. Find the average angle at which the airplane must descend for landing. Round your answer to the nearest

degree.

Answers

Answer:

4degrees

Step-by-step explanation:

Given the following

Height of the airplane = 37000feet

distance covered on landing = 100miles = 100(5280)

distance covered on landing = 528,000feet

Using the SOH CAH TOA

sin theta = opposite/hyp

sin theta = 37000/528000

sin theta = 37/528

theta = arcsin (37/528)

theta = 4 degrees

Hence average angle at which the airplane must descend for landing is 4degrees
