3. A function f(x) has a slope of -and passes through
the point (-3,7). Explain how the graph of f(x)
could be used to find the y-intercept.
Answer:
Well. this is kinda trivial.
For a function f(x) = y.
The y-intercept is defined as the point where the graph of f(x) intersects the x-axis.
This always happens at x = 0.
So the y-intercept is equal to f(0).
Now, if we have the graph of f(x), you simply can see at what value of y does the graph intersect the x-axis, and that will be the y-intercept.
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

find the mean and median for the following.
Answer:
mean = 6
median = 7
Step-by-step explanation:
mean: add all values and divide by the number of values
median: place all values in ascending order and choose the middle value; if there is an even number of values, the median is the mean of the two middle values.
There are 5 values: 7, 8, 8, 4, 3
a) mean
Add all values and divide by the number of values.
mean = (7 + 8 + 8 + 4 + 3)/5 = 30/5 = 6
mean = 6
b) median
Place values in ascending order.
3, 4, 7, 8, 8
The middle value is 7.
median = 7

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

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
