How fast does each boy walk?
Answers
Answer:
75 miles miles an hour. (First one)
5 mph for the second one.
Step by Step:
1800%2F3 = u + v (1) is the equation for the flight with the wind.
(Here "u" is the airspeed of the airplane with NO wind,
"v" is the wind speed)
1800%2F4 = u - v (2) is the equation for the flight against the wind.
Simplify equations (1) and (2) and write them as a system:
u + v = 600, (1')
u - v = 450. (2')
Now add the two equations (1') and (2'). You will get
2u = 1050 ---> u = 1050%2F2 = 525 miles per hour.
Having this, you can easily determine "v" from (1'):
v = 600 - 525 = 75 miles per hour.

Second one will be 15 divided by 3 = 5mph

Doug left home for his destination and drove for the first 2 hours on a state road at a constant rate of 50 miles per hour. For the next 3 hours, he drove on an interstate highway at a constant rate of 60 miles per hour. How many miles from home was he when he arrived at his destination 5 hours later?
_______miles
Answers
Answer: In the first 2 hours, Doug drove 2 * 50 = <<250=100>>100 miles on the state road.
In the next 3 hours, he drove 3 * 60 = <<360=180>>180 miles on the interstate highway.
Therefore, he drove a total of 100 + 180 = <<100+180=280>>280 miles.
Since we don't know his distance from home before he began driving, we cannot calculate his distance from home after 5 hours of driving.
Step-by-step explanation:
50 = <<250=100>>100 miles on the state
road.
In the next 3 hours, he drove 3 * 60 = <<360=180>>180 miles on the interstate highway.
Therefore, he drove a total of 100 + 180 = <<100+180=280>>280 miles.

What is the total height of all the plants?
Answers
Answer: 6 1/8
Step-by-step explanation:
1/8 x 2 = 1/8 x 2/1 = 2/8 = 1/4
1/4 x 3 = 1/4 x 3/1 = 3/4
3/8 x 4 = 3/8 x 4/1 = 12/8 = 1 4/8 = 1 1/2
1/2 x 3 = 1/2 x 3/1 = 3/2 = 1 1/2
5/8 x 1 = 5/8 x 1/1 = 5/8
3/4 x 2 = 3/4 x 2/1 = 6/4 = 1 2/4 = 1 1/2
Start with the big number first.
1 1/2 = 1 4/8
1 1/2 = 1 4/8
1 1/2 = 1 4/8
5/8 = 5/8
3/4 = 6/8
1/4 = 2/8
Add them all up.
1 4/8 + 1 4/8 = 2 8/8 = 3
3 + 1 4/8 = 4 4/8
4 4/8 + 5/8 = 4 9/8 = 5 1/8
5 1/8 + 6/8 = 5 7/8
5 7/8 + 2/8 = 5 9/8 = 6 1/8

11. A scuba diver's elevation changed by -123 feet every minute. This was
1½ times the rate of change for a second scuba diver. What was the rate of
change in elevation of the second scuba diver in feet per minute?
Answers
Answer:
The rate of change in elevation for the second scuba diver is -82 feet per minute.
Step-by-step explanation:
-123 feet every minute.
1.5x more than 2nd diver.
-123/1.5 = 2nd diver rate
2nd diver rate = -82
The rate of change in elevation of the second scuba diver in feet per minute is -82 feet per second.
Given that, a scuba diver's elevation changed by -123 feet every minute.
What is constant rate of change?When something has a constant rate of change, one quantity changes in relation to the other. For example, for every half hour the pigeon flies, he can cover a distance of 25 miles. We can write this constant rate as a ratio. For ratios, it's always a good idea to state both units in whole terms.
1½=1.5 times the rate of change for a second scuba diver
Now, rate of change in elevation of the second scuba diver
= -123/1.5
= -82 feet per second
Hence, the rate of change in elevation of the second scuba diver in feet per minute is -82 feet per second.

Use a number line to order the numbers from least to greatest.
Answers
Assign the numbers to the number line in the following order:
2.15=2.15
220%=2.2
9/4=2.25
*2.15* is easy enough to place as it is already in decimal form. However, the other 2 options need to be converted to decimals in order to be placed. We have the fraction 9/4 and percentage 220%. 9/4 can either be simply divided on a calculator or turned into the mixed fraction 2 and 1/4, which is *2.25*. Finally, we know that converting a decimal to a percentage we multiply the decimal by 100. Therefore, to convert a percentage to a decimal we divide 100 or move the decimal to the left 2 places. With this conversion rule, 220% transforms to *2.2* and we have the third and final number for our number line. Arranging these three numbers from least to greatest:
2.15, 2.2, 2.25
if 4/4 is 1 then 9/4 is 2 whole with 1/4 left
220%=2.2 and 2.15 is still 2.15

An investor has an account with stock from two different companies. Last year, his stock in Company A was worth $6100 and his stock in Company B was worth $6480. The stock in Company A has decreased 2% since last year and the stock in Company B has decreased 10%. What was the total percentage decrease in the investor's stock account? Round your answer to the nearest tenth (if necessary).
Answers
Investment in Company A by investor = $6100
Investment in Company B by investor = $6480
The decrease in value of the stock of company A is 2%
The decrease in value of the stock of company B is 10%
Value of wealth that investor lost in company A = 6100× 2/100
= 61×2
= $122
The decline in the value of the stock of company B = 6480×10/100
= 648×1/1
= $648
The total decline in the wealth of the investor= 122+648
= $770
The combined wealth of investor in both companies= 6100+6480
= $12580
Percentage of decline in the stock account of investor= 770×100/12580
= 77000/12580
= 6.1%
The total percentage decline in investor's stock account is 6.1%
