Answer:
1. Lin 6 7/8 miles, Noah 6 1/2 miles
2. Lin will take 8 8/11 minutes while Noah will take 9 3/13 minutes
3. Lin ran faster because it took him less amount of time to cover same distance of 1 hour
Step-by-step explanation:
Here, we are told that Lina ran 2 3/4 miles in 2/5 of an hour while Noah ran 8 2/3 miles in 4/3 of an hour.
1. We want to know how far Noah will run in an hour
1 hour is 60 minutes;
So 4/3 of an hour is 4/3 * 60 = 80 minutes
thus;
if he ran 8 2/3 miles in 80 minutes
then he ran x miles in 1 hour(60 minutes)
8 2/3 is same as 26/3 miles
Thus;
26/3 * 60 = 80 * x
x = 26/3 * 60/80 = (26 * 20)/80 = 26/4 = 13/2 = 6 1/2 miles
Lin ran 2 3/4 miles in 2/5 hour (2/5 * 60 = 24 minutes)
2 3/4 miles took 24 minutes
x mile will take 60 minutes
60 * 2 3/4 = 24 * x
60 * 11/4 = 24x
165 = 24x
x = 165/24
x = 6 21/24 = 6 7/8 miles
Lin will run 6 7/8 miles in an hour
2. we want to know how long it will take both of them to run 1 mile
Lin ran 2 3/4 miles in 2/5 of an hour
meaning, he ran 2 3/4 in 2/5 * 60 = 24 minutes
2 3/4 miles was ran in 24 minutes
1 mile will take x minutes
1 * 24 = 2 3/4 * x
24 = 11/4 * x
x = 4 * 24/11 = 96/11 = 8 8/11 minutes
For Noah
6 1/2 miles was ran in 1 hour
1 mile will be ran in x hours
13/2 * x = 60 minutes * 1
x = (2 * 60)/13
x = 120/13
x = 9 3/13 minutes
c. Lin ran faster because he took the lesser amount of time to travel 1 mile
Answer:
1. Lin 6 7/8 miles, Noah 6 1/2 miles
2. Lin will take 8 8/11 minutes while Noah will take 9 3/13 minutes
3. Lin ran faster because it took him less amount of time to cover same distance of 1 hour

1 mile will be ran in x hours
13/2 * x = 60 minutes * 1
x = (2 * 60)/13
x = 120/13
x = 9 3/13 minutes
c. Lin ran faster because he took the lesser amount of time to travel 1 mile
b) 10 + 2x = x +13
X =
x is equal to 3 if not then I just we are asking the wrong questions
Mrs.; Jones bought 25 mangoes for $7.50. She sold 12 mangoes for 60 cents each and the remainder for 55 cents each. Calculate her percentage profit or loss. State whether she made a profit or loss

Leo and Vanessa both have a certain amount of money and plan to spend a certain amount each week until they run out. Vanessa starts with $400 and plans to spend $80 every 2 weeks. Leo plans to spend his money half as fast and has the same amount of money as Vanessa after 7 weeks.
Answer:
Leo started with $260
The balance of Vanessa and Leo after 7 weeks = $120
Step-by-step explanation:
Vanessa started $400
Vanesaa spending rate= $80/2weeks
In a week she would spend=$40/week
In 7 weeks should spend =40*7 = $280
Her balance after 7 weeks is =
$400 - $40 × x
$400 - $280
= $120
Leo spends at half of vanessa’s rate= $20/week
In 7 weeks leo will spend
$20 × x weeks
= 20 × 7 = $140
Since Leo and Vanessa’s balance would be the same after 7 days then leo balance is $120
Hence, the amount Leo started with $120 + $140= $260
In order to confirm your above answer
The Equation can be given as
$400 - $40 ×x = $260 - $20 × x
Where x = 7 weeks
$400 -40x = 260 - 20x
$400 - 40× 7 = $260 - 20× 7
$400 - 280 = $260 - 140
$120 = $120

B) -1/2, 1.3, 7,12, -0.45, 0.82
C) -0.45, -1/2, -2/3, 7/12, 0.83
D) -0.45, -1/2, 7/12, -2/3, 0.82
Answer:
c
Step-by-step explanation:
a has a positive before negative, so its ruled out
1.3 is more than -0.45, so b is ruled out
everything in c is in the right order. -1/2 is -0.5 and -2/3 is -0.66, 7/12 is -.58
d is incorrect because -2/3 isnt more than 7/12

A. how many full bags of mulch will the store make?
B. considering only the full bags, what is the total sales price of all the
bags of mulch?
Answer:
The store will make 24 bags
total sales will be $55
Step-by-step explanation:
finding the number of bagsade by the store,
compare, 2 1/4 pounds= 1 bag
77 1/2 pounds= ? bags
cross multiplication
number of bags the store will make will be 24 4/9 bags.
considering the full bags only which are 24 then the number of full bags the store will make are 24 bags.
total sales will be 1 bag= $2.25
24bags= ?

find the measure of the missing angles
b=
c=
Answer:
b=20
c=160
Step-by-step explanation:
b has the same measurement as the other angle that is across from it. c is 160 because the line that c is on is a straight line so it is 180 degrees, you subtract the other angle on the line,20, then you get the answer.
Answer:
b = 20° ( vertically opposite angles are equal)
b + c = 180°
=> 20 + c = 180
=> c = 180 – 20
=> c = 160°

1. George works for a tech company. He has worked there for 5 years. He makes
$81,536 a year. He started with 8 days of paid vacation time. For each year he works at
the company he gains another three days of paid vacation to a max of 30 days.
a. How many paid vacation days does he now have?
Answer:
George now has 20 paid vacation days
Step-by-step explanation:
The given parameters are;
The number of years George has worked for the tech company = 5 years
The amount George makes annually while working for the company = $81,536
The starting amount of paid vacation time George has each year = 8 days
The annual increase in the amount of paid vacation time George has each year = 3 days
The maximum number of days of paid vacation allowable = 30 days
a. The number of paid vacation days George now has is given as follows;
The first year George had 8 days paid vacation
The next year George had 8 + 3 = 11 days paid vacation
The third year George had 11 + 3 = 14 days paid vacation
The fourth year George had 14 + 3 = 17 days paid vacation
The fifth year George had 17 + 3 = 20 days paid vacation
Therefore, George now has 20 paid vacation days.
