Ned rides his bike 6 miles to the store and 6 miles back. The graph shows the relationship between the distance Ned is from home at any time throughout his trip and the distance he spends riding the bike. Which statement is true about Ned's ride?
A. Ned's speed is constant for the entire ride from 0 to 90 minutes
B. Ned's speed is constant on the interval from 0 to 60 minutes.
C. Ned's speed between the interval from 20 to 40 minutes is the same as his speed over the interval 50 to 90 minutes.
D. Ned's speed over the interval from 20 to 40 minutes is faster than his speed over the interval from 0 to 20 minutes.
Answers
Answer:
The answer is D
Step-by-step explanation:
A cant be right because the graph isn't a straight line.
B cant be right because from 0 to 60 the graph the line goes at a(n) upward slope not a straight line.
Although the first part of question c is right, the second part is wrong. From 50-90 the ling goes at a downward slope via decreasing, which isn't equal like it said so question C is wrong.
So the correct answer is D

a big beach towel has a width that is 3 feet less than its length. Of the towels area is 28 feet, what is its length
Answers
Answer:
the answer is 9.333
Step-by-step explanation:
because if the towel of the width that is 3 feet less so you do 28/3=9.333
Answer:
length = 7 ft
Width = 4 ft
Step-by-step explanation:
length = l
Width = l -3
Area = 28 sq.ft
length *width = 28
l*(l-3) = 28
l*l - l*3 = 28
l² - 3l - 28 =0
l² - 7l + 4l - 28 = 0
l(l - 7) + 4(l - 7) = 0
(l -7) (l + 4) =
l -7 = 0 {Ignore l + 4 = 0 as , it gives a negative value}
l = 7 ft
width = 7 - 3= 4
A squirrel burrowed 10 holes in 8 minutes. How many holes could the squirrel burrow in 12 minutes?
Answers
Answer:
15
Step-by-step explanation:
Fast and loose: To go from 8 to 12 minutes you're adding half the time (4 minutes). So it has time to burrow only half the holes in the extra time, so 5. Total, 10+5=15.
Crunching numbers: it's a simple proportion:[tex]10:8 = x :12[/tex] from which, cross-multiplying you get [tex]8x=12\times10 \rightarrow 8x=120 \rightarrow x=15[/tex]

the cost of 6 kg of oranges is rs 540 how many kilograms of oranges can be purchased for rs 720
Answers
Answer:
This will clear you
Step-by-step explanation:
Given:-
Cost of 6 kg oranges =540
Cost of 1 kg oranges =540/6
=90
Now,
Orange can be purchased =720-540
=180
Again,
Remaining rupees =180/90
=2
Also,
We can buy oranges = 6kg+2kg
=8kg
If the cost of 6 kg of oranges is rs 540, for Rs. 720, you can purchase 8 kilograms of oranges.
To find out how many kilograms of oranges can be purchased for Rs. 720, we need to calculate the cost per kilogram of oranges.
Given that the cost of 6 kg of oranges is Rs. 540, we can find the cost of 1 kg of oranges by dividing Rs. 540 by 6:
Cost of 1 kg of oranges = Rs. 540 / 6 = Rs. 90
Now that we know the cost of 1 kg of oranges is Rs. 90, we can determine how many kilograms of oranges can be purchased for Rs. 720 by dividing Rs. 720 by the cost per kilogram:
Kilograms of oranges that can be purchased = Rs. 720 / Rs. 90 = 8 kg
So, for Rs. 720, you can purchase 8 kilograms of oranges.
In summary, to find the kilograms of oranges that can be purchased for Rs. 720, we divide the given amount by the cost per kilogram, which is obtained by dividing the cost of 6 kg of oranges by 6. The result is 8 kg of oranges that can be bought for Rs. 720.
