Unit rate is the quantity of an amount of something at a rate of one of another quantity.
If 15 bananas cost $9.
The cost of one banana is $0.6
The amount of banana per dollar is 5/3 banana
What is a unit rate?It is the quantity of an amount of something at a rate of one of another quantity.
In 2 hours, a man can walk for 6 miles.
In 1 hour, a man will walk for 3 miles.
If a machine can make 100 bottles in 20 minutes.
In 1 minute the machine can make 100/20 = 5 bottles.
We have,
Cost of 15 banana = $9
This can be written as:
15 banana = $9
Divide 9 on both sides.
15/9 banana = $1
5/3 banana = $1
The cost of one banana:
15 banana = $9
1 banana = 9/15
1 banana = 3/5
1 banana = $0.6
Thus,
If 15 bananas cost $9.
The cost of one banana is $0.6
The amount of banana per dollar is 5/3 banana

A phone line runs east along a field of 1 miles and then north along the edge of the same field for 3 miles. If the phone line cost 3500 per mile to install, how much could have been saved if the phone line had been installed diagonally across the field?

Answer:
nsnenenenwnneennenewnw
let L to be the length of diagonal line, so L^2 = 1.8^2 + 2.75^2 =>3.29

Daniel and Saquon are each saving money.
Daniel starts with $50 in his savings account and adds $8 per week.
Saquon starts with $65 in his savings account and adds $5 each week.
QUESTION: After how many weeks will Daniel and Saquon have the same amount of money in their savings account?
Answers
Daniel starts with $50 and each week he adds $8. To find out the amount he has in any given week, the following formula would work:
= 50 + 8x
The x is the number of weeks and is multiplied by 8 because the amount of money he has increase by 8 every week.
After 4 weeks he would have:
= 50 + (8 * 4)
= 50 + 32
= $82
Saquon
Applying the same formula:
= 65 + 5x
After 4 weeks:
= 65 + (5 * 4)
= 65 + 20
= $85
Saquon has more money after 4 weeks.
Number of weeks it would take for both of them to have the same amount.
To find this out, equate both formulas and solve for x.
50 + 8x = 65 + 5x
8x - 5x = 65 - 50
3x = 15
x = 15/3
x = 5 weeks
At 5 weeks they will both have:
50 + 8 * 5 = $90
65 + 5 * 5 = $90

BC is double the length of DE. And we know that DE is equal to 15. So 15 x 2 is 30.
Now to find x. We know that our answer has to add up to 30. So we first subtract 3 from 30 to get 27. Then divide 27 by 2 to get what x is equal to. x = 13.5

X+4,x+12,x-1 and x+5 are in proportion.find the value of x
Answers
Answer:
Step-by-step explanation:
As they are in proportion,
x +4 : x +12 :: x -1 : x + 5
Product of means = Product of extremes
(x + 12)(x -1) = (x +4)(x+5)
Use FOIL method for polynomial multiplication
x*x + x*(-1) + 12*x + 12*(-1) = x*x + x*5 + 4*x + 4*5
x² - x + 12x - 12 = x² + 5x + 4x + 20
Combine like terms
x² + 11x - 12 = x² + 9x + 20
x² + 11x - 12 - x² - 9x - 20 = 0
Combine like terms
x² - x² + 11x -9x -12 -20 = 0
2x - 32 = 0
2x = 32
x = 32/2
x = 16
