Lin ran ran 2 3/4 miles in 2/5 of an hour. Noah ran 8 2/3 miles in 4/3 of an hour.
1. How far would Lin and Noah run in 1 hour?
2. How long would it take Lin and Noah to run 1 mile at that rate?
3. Who ran faster, Noah or Lin and why?
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
Step-by-step explanation:
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

A rectangular pool has an area of 5x2 + 23x + 12 and the length of one side is 5x + 3. What is the
length of the other side?
Answer:
x + 4
Step-by-step explanation:
Area of rectangle= length × breadth
In this question, one length is 5x + 3 and the area is 5x^2 + 23x + 12
This means that;
5x2 + 23x + 12 = 5x + 3 (b)
Hence, to get the other length (b) = 5x2 + 23x + 12/ 5x + 3
To get the other length, we can factorize the algebraic expression;
5x2 + 23x + 12
Product: 60x^2 (20x × 3x)
Sum: +23x (20x + 3x)
Hence;
= 5x^2 + 20x + 3x + 12
Next, we find factors;
5x (x+4) + 3 (x+4)
Therefore, the factors are (5x + 3) and (x +4)
This means that the other length is (x +4)
Barbara bought 5 amusement park tickets at a cost of $30. If she bought 7 tickets, how much would it cost?
It would cost $
.
Answer:
$42
Step-by-step explanation:
5 divided by $30 so each ticket would be $6 then just multiply $6 and 7
Answer:
It would cost $42 because 30 divided by 5 equals 6, so that's saying for each 1 ticket it costs $6. So with the new equation, 7 x $6, we get $42. Which will end up being the cost for 7 tickets.

If a business receives an invoice for services purchased on account on December 1st for $8,000, how much should the business write a check for to pay the invoice in full on December 8th if the terms are 1/10, n/15?
Answer:
The amount that should be written on the check is $7920
Step-by-step explanation:
The explanation of the question is given as:
1/10 = 1% discount to be given if paid within 10 days
n/15 = full amount to be paid within 15 days.
From the question, we can see that:
If the check for the invoice is given on December 8th, it is still within the discount time of 10 days.
Discount amount = $8000 × 1%
= $80
$8000 - $80
= $7920
Hence, the amount that should be written on the check is $7920
Ruth went out to eat with friends. She brought a $50 bill. She bought an appetizer for $8.50, an entree for $13.99, and desert for $6.50. She wants to leave a 20% tip for the good service she received. How much is the tip she will leave? Do not round your answer, but keep in mind that the smallest unit in our financial system is a penny which stops in the hundredths place. *
Answer:
$16.81
Step-by-step explanation:
$50.00 -$8.50 - $13.99 - $6.50 = $21.01
$21.01 * 0.20 = $4.20
$21.01 - $4.20 = $16.81

I need some help with this problem
Answer:
-6
Step-by-step explanation:
First you need to substitute -1 in for x in -2x^2
This makes it (-2)(-1)^2
-2x^2 becomes -2 so this means that the equation is now
-2 + (-1) - 3
-2 + (-1) = -3
-3 - 3 = -6
One meaning of the word rigid is "not bendable", and another is "unable to be changed". How do those meanings correspond to the definition of rigid motion?
Answer:
The meaning of rigid corresponds with rigid motion
Step-by-step explanation:
Rigid motion in geometry occurs when a point or object is moved, but the size and shape remain the same. It is also referred to as RIGID TRANSFORMATION.
Therefore, the meaning of the word rigid, which means "not bendable", and another is "unable to be changed" corresponds to the definition of rigid motion.
Rigid means unable to move or remain stagnant.
The rectangle shown is composed of smaller equally-sized squares. The shaded section has an area of 3/16 square inches. Use a unit rate to determine the area of the larger rectangle.
Answer:
Area of larger rectangle = 1½ = 1.5 in²
Step-by-step explanation:
The section consists of 3 small squares that has an area = [tex] \frac{3}{16} in^2 [/tex].
Area of 3 small squares = [tex] \frac{3}{16} in^2 [/tex]
Area of 1 small square = [tex] \frac{3}{16} [/tex] ÷ 3
= [tex] \frac{3}{16} * \frac{1}{3} [/tex]
= [tex] \frac{3*1}{16*3} = \frac{1}{16} [/tex]
The larger rectangle has 24 small squares of equal sizes
Area of larger rectangle = area of 1 small square * 24
= [tex] \frac{1}{16} * 24 [/tex]
[tex] = \frac{24}{16} = \frac{3}{2} [/tex]
Area of larger rectangle = 1½ = 1.5 in²
