Answer:
A proportional relation is a logical relation that establishes a range of conditional relations that together involve direct or inverse correlation.
Some common unit rates are miles (or kilometers) per hour, cost per item, earnings per week, etc. In each case the first quantity is related to 1 unit of the second quantity.
A unit rate describes how many units of the first type of quantity corresponds to one unit of the second type of quantity.
I have to make sure that there is at least one variable that directly effects another.
Some equations are y = 3x, y = 1.5x, and y = 2/3x.

Tom and Sam can finish a plowing job in two hours. Tom working alone can do the job in 7 hours. How long would it take Sam to finish the same job alone?
Answer:
Step-by-step explanation:
1X+17=121X+17=12
1X=12−171X=12−17
1X=72×7−27×21X=72×7−27×2
1X=7−2141X=7−214
1X=5141X=514
Taking inverse on both sides
X=145=2.8 hoursX=145=2.8 hours
The time taken by Sam is 2.8 hours.2.8 hours.
helppp pleasee?.......um yea...
Answer: Snail ≈ 96,551.7 hours, North American X-15 ≈ 0.6 hours
Step-by-step explanation:
All you have to do is divide how many miles they go an hour by the total number of miles, which is 2,800.
Part 1: Garden Snail
= [tex]\frac{2,800}{0.029}[/tex]
≈ 96,551.7
Part 2: North American X-15
= [tex]\frac{2,800}{4,520}[/tex]
≈ 0.6
These are the answer!
Hope this helps! :)

d, 800g : 2kg
f, 5days : 5weeks
h,40sec : 1min
j, 800ml : 1l
l, 10cm : 80cm
pls tell me the answers i will give 5stars
Answer:
......
Step-by-step explanation:
b)4kg:1600g
convert 4kg to grams
4000g:1600g
then divide
=5g:2g
then convert 5g into kg
=0.005kg:2g
f)5 days:5 weeks
multiply 5weeks by 7 u will get 35
5days :35dys then divide by 5
1:7days
=1 day:1 week
h)40 sec:1 min
40 sec:60 sec
then divide both of them by 2
2 sec:3 sec
then take 3 ÷60=0.05 min
=2 sec:0.05 min

Please help been stuck on this hw question ALLL DAYYYYYY
Answer:
1 5/9
Step-by-step explanation:
9 1/3 can be rewritten as 28/3. The question is asking for you to divide 28/3 by 6. 6 is 6/1, so the expression is 28/3 divided by 6/1. You then do the reciprocal of 6/1 and the expression is [tex]\frac{28}{3} * \frac{1}{6}[/tex]. This gets you 28/18, which is simplified to 14/9 or 1 5/9. Hope this helps!

If the sum of 4040 consecutive integer numbers is 2020, find out the absolute difference between the first number and the last number.
Let [tex]x[/tex] be the smallest of the consecutive integers summing to 2020. Then the largest integer in the sum is [tex]x+4039,[/tex] so our answer is [tex]\boxed{4039}.[/tex]
For completeness, though, let's solve for the value of [tex]x[/tex] that satisfies the conditions of the problem. Recall that the sum of an arithmetic series with first term [tex]a_1,[/tex] last term [tex]a_n,[/tex] and [tex]n[/tex] terms, is [tex]\frac{n(a_1+a_n)}{2}.[/tex] Plugging in our known values gives us the equation [tex]\frac{4040(2x+4039)}{2}=2020,[/tex] which simplifies to [tex]2x+4039=1.[/tex] Thus, [tex]x=-2019,[/tex] so the 4040 consecutive integers are [tex]-2019,-2018,\dots,-1,0,1,\dots,2018,2019,2020.[/tex] Notice how everything except the [tex]2020[/tex] cancels out!

Line segments AB and BC are tangents to Circle P. What is the value of x?
a.117
b.73
c.107
d.146
Answer:
c. 107°
Step-by-step explanation:
In the figure attached, Circle P, segments AB and BC, and angle x are shown.
From circumscribed angle theorem, we know that angle ABC and angle x are supplementary, then:
x + 73° = 180°
x = 180° - 73°
x = 107°

What is the surface area that will be frosted with icing?
A.24 in
B.117 in
C.205 in
D.322 in
Answer: B. 117 in
Step-by-step explanation:Took the test Trust
Hope this helps -----
The surface area that will be frosted with icing is 205in²
What is the surface area that will be frosted with icing?
It will be equal to the sum between the top surface, which measures:
S = 13in*9in = 117 in²
And the four lateral sides, two of them measure:
s' = 2in*9in = 18in²
The other two measures:
s'' = 13in*2in = 26in²
Then the total surface area that must be frosted is:
SA = 117 in² + 2*( 18in²) + 2*(26in²) = 205 in²
So we conclude that the correct option is C.
