Divide. Reduce the answer to the lowest terms.
3/8 ÷ 1/7
Answer:
21/8
Step-by-step explanation:
3/8 x 7/1 = 21/8
Answer:
(21/8) (no parenthesis required)
or
2 and 5/8 (no "and" required)
Step-by-step explanation:
When you divide fractions, multiply the first number by the reciprocal of the second (2/3's reciprocal is 3/2 and 5/8's reciprocal is 8/5)
3/8 ÷1/7
= (3/8)*(7/1)
then multiply the numerators together and put them over the denominator
=21/8
= 2 and 5/8

Aro diagrams his river rafting trip, estimating the time it will take him to paddle upstream against the current, and then back downstream with the current. His campsite destination is 5.2 miles upstream. Determine how fast Aro can paddle and how fast the river water is moving. Round to the nearest hundredth as needed.
Upstream:
Downstream:
Let x be the speed of Aro’s paddling and let y be the speed of the river.
Upstream: 1.04 = x – y
Downstream: 2.08 = x + y
Aro can paddle at a speed of
miles per hour.
The river’s speed is
miles per hour.

The equation of the line is y = 2x - 2.
What is the point-slope form of a line?If m is the slope of the line that passes through the point (x₁, y₁), then the equation of the line is y - y₁ = m (x - x₁).
The graph of the line is given.
(1)
The line passes through points (2,2) and (6,10).
The slope of the line is:
m = (10 - 2)/(6 - 2)
m = 8/4
m = 2
(2)
The equation of the line with a slope of m =2 and passes through (2,2) is:
y - 2 = 2(x - 2)
y = 2x - 4 + 2
y = 2x - 2 (1)
(3)
The line passes through points (4,b) and (a,8), therefore, from equation (1):
b = 2(4) - 2
b = 6, and
8 = 2a - 2
2a = 10
a = 5
(4)
Substitute x = 0 into equation (1):
y = 2(0) - 2
y = -2
Hence, the equation of the line is y = 2x - 2.

Jackson receives 4.63 as his change at the grocery store. He places it into a charity donation jar at the register. Write an addition equation to represent Jackson's net change in money. Enter your answer as an addition equation, formatted like this: 42+(-53)=-11
Answer:
x + (-y) = 4.63
Step-by-step explanation:
Given that :
change received = 4.63
Net change in money :
Let initial amount before purchase = x
Cost of item purchased = y (negative as it is incurred)
Net change in money:
Initial amount + cost of item purchased = change received
x + (-y) = 4.63
Lawrence bought 2/3 pound of roast beef. He used 3/4 of it to make a sandwich. How much beef did he use for his sandwich A 5/12 pound B 1/2 pound C 5/7 pound D 6/7 pound
Answer:
B) 1/2 pound
Step-by-step explanation:
Lawrence bought 2/3 pound of roast beef.
He used 3/4 of it to make a sandwich.
The amount of beef that he used for his sandwich is calculated as:
3/4 of 2/3 pounds of roast beef
3/4 × 2/3
= 6/12 pound
= 1/2 pound

A golf ball is hit with an initial velocity of 100 feet per second. The height of the golf ball can be represented by the equation h=100t−16t^2, where t is the time in seconds since the ball was hit and h is the height of the ball in feet. How long will it take for the ball to hit the ground?
Answer:
6.25 secondsStep-by-step explanation:
Using the the equation
h = 100t − 16t^2The ball hits the ground, when h = 0, solving below equation:
100t − 16t^2 = 04t(25 - 4t) = 0t = 0 seconds, this is the starting point when ball was hit25 - 4t = 0 ⇒ 4t = 25 ⇒ t= 25/4 = 6.25 seconds later the ball hits the groundAnswer:
6.30 seconds

The grass in Jamie's yard grew 16 centimeters in 10 days. It was growing at a constant rate.
Answer:
1.6 cm
0.625 day
Step-by-step explanation:
We are given that the grass in Jamie's yard grew 16 cm in 10 days.
It was growing at constant rate.
We have to find number of days taken by the grass to grow 1 cm and how many cm grass grow in one day.
In 10 days , grass grow=16 cm
In 1 day, grass grow=
Grass takes time to grow 16 cm=10 days
Grass takes time to grow 1 cm==0.625 days
Hence, the grass grow 1 cm in 0.625 days and the grass grow 1.6 cm in one day.
Answer:
1.6cm/day
Step-by-step explanation:
Propoertions:
16cm ⇔ 10 days
Y cm ⇔ 1 day
Y = 16*1/10
y = 1.6cm
The constant rate:
1.6 cm / 1 day

Answer: Yes, the equations are correct.
x represents the time that one individual act takes.
y represents the time that one group act takes.
Step-by-step explanation:
the first statement says:
"The first show will last 2 hours, and 12 individual acts, and 6 group acts"
He writes this as:
12*x + 6*y = 120.
then x represents the time that individual acts take.
6 represents the time that group acts take.
120 represents the time in minutes (120 min = 2 hours).
The second statement says:
"The final show will last 30 minutes, and it will include the top 4 individual groups, and the top group act."
this is written as:
4*x + 1*y = 30
And it is consistent with the thing we saw above.
At the right, we have time in minutes, 30 minutes.
x represents the time that each individual act needs, and in this case, we have 4 individual acts.
and y represents the time that the group acts need, and we have only one group act in this case.
Then yes, you must agree with your classmate.

a fitness club opens up with 80 members. Each month the membership increases by 15 members. Which equation represents the relationship between the number of months the club has opened, x, and the total club membership,y?
Answer:
15x+80=m
Step-by-step explanation:
where x is the number of months and m is the amount of members
Answer/Step-by-step explanation:
y = 15x + 80
The club start with 80. Then each month 15 people are added so the slope is 15. So replace m in the equation y = mx + b with 15.
Next, replace the variable b of y = 15x +b with 80. because the original 80 members is a one time thing that stays there.
Now you have the equation y = 15x + 80. Which correctly describes the fitness club's situation.

Is the following relation a function? Yes or no
Answer:
It is a many-to-many function but not a one-to-ine function hence, it cannot be represented a a function in an expression
Step-by-step explanation:
Topic: Functions
If you would like to venture further into mathematics, you can check out my Instagram page (learntionary) where I post notes and mathematics tips. Thanks!
Answer: No
Explanation: I think that the least confusing way to do
this problem is to first write down the ordered pairs that
are represented by this mapping diagram.
So we have {(6,3), (-1, 2), (-1, -1), (4, 3)}.
In order for a relation to be a function, each x-coordinate needs
to appear once unless we have a repeated ordered pair.
Since we have the same x-coordinate in two of
our ordered pairs, this relation cannot be a function.
In terms of the mapping diagram, you can see that we have
an x that is paired with two different y's.
So this does not fit the definition of a function which states
that each x must be paired with exactly one y.
