Juan made $253 for 11 hours of work. At the same rate, how many hours would he have to work to make $391?
Answer:
17 hours
Step-by-step explanation:
givens:
-he made $253 for 11 hours of work
-how many hours of work for $391
set a proportion
253 391
----- = ----
11 h h=hours
cross multiply
253h=391 times 11
253h=4301
divide 253 in both sides
4301/253
17 hours!
If y=15 when x=5, find y when x=7, given that y varies directly with x.
Answer:
when x = 7, y = 21
Step-by-step explanation:
This is about direct variation. If y varies directly with x, then there is a constant factor of variation, k. The constant of variation can be found by ʸ⁄ₓ
k = ʸ⁄ₓ
k = ¹⁵⁄₅ = 3
Now that we have found k, we simply multiply x by it to find y (this is because y is directly proportional to x). We plug in our x = 7 to find y at this point.
y = 3x
y = 3(7)
y = 21
f-4=6f + 26 what is f
Answer:
the answer is f=-6
Answer:
f = - 6
Step-by-step explanation:
Step 1:
f - 4 = 6f + 26 Equation
Step 2:
- 4 = 5f + 26 Subtract f on both sides
Step 3:
- 30 = 5f Subtract 26 on both sides
Step 4:
f = - 30 ÷ 5 Divide
Answer:
f = - 6

Write an equation in slope-intercept form of a line that passes through the point (8,-0) and is perpendicular to the line x - 3y = 15.
y = 3x −24y = 3x −24
y = 3x + 24
y = -3x + 24
y = -3x - 24
Step-by-step explanation:
let eqn be y = mx + b.
3y = x - 15
y = 1/3x - 5
perpendicular means product of grad = -1
hence m = -3.
sun (8, 0):
8 = -3(0) + b
b = 8
therefore, equation if the line is y = -3x + 8

Which of the following does not represent a function?
PLEASE HELPP ME
15 POINTS OR BRAINLIEST ?!??
Answer:
G is not a function
Step-by-step explanation:
Answer:
H.
Step-by-step explanation:
something is represented as a function when none of the inputs (x) repeat, but the outputs (y) change. the graph for letter G has repeating x values, but the y values don't change when an x repeats. however, the graph for letter H has repeating inputs (x), but the outputs are different, even with the same input.
that's why parabolas aren't functions (if you know what those are).
hopefully that helps and isn't too confusing! if you need anything else, let me know! :)
Joe Howard earns an annual gross pay of $955,520 as a
professional baseball player. He is married with 4 dependents.
How much is withheld from his monthly paycheck for state
income tax?
Answer: 3924.25
Step-by-step explanation:
0.0150x1000=15
0.0300x2000=60
0.0450x2000=90
0.0500x938520=46926
Add the numbers
47091÷12=3924.25
Additional work:
955520-12000=943520-1000=942520-2000=940520-2000=938520
His monthly paycheck for state income tax is $19,906.65.
What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For exmaple, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
Annual Gross pay = 955520
He is married with 4 dependents.
So, every month he earn
= 955520/12
= 79,626.6
and, Also have 4 dependents
= 79,626.6 /4
= 19,906.65
Hence, his monthly paycheck for state income tax is $19,906.65.

In triangle DEF, segment DJ is a perpendicular bisector of side EF. If EJ is 3y-8 and JF is 7y-40, what is the length of JF?
Answer: The length of JF = 16 units.
Step-by-step explanation:
Given: In triangle DEF, segment DJ is a perpendicular bisector of side EF.
i.e. DJ is perpendicular to EF and DJ divides EF into two equal parts EJ and JF. [The perpendicular bisector is a line that is perpendicular to a line segment and splits it into two congruent segments.]
If EJ is 3y-8 and JF is 7y-40.
Then, [tex]3y-8=7y-40[/tex]
[tex]\Rightarrow\ 7y-3y=40-8\\\\\Rightarrow\ 4y=32\\\\\Rightarrow\ y=8 \text{ [Divide both sides by 4]}[/tex]
JF= 7(8)-40 =56-40= 16 units
Hence, the length of JF = 16 units.
