HELP ASAP I ONLY HAVE 2 MINS
Each month, Ellie spends 4 hours in tap class at her dance studio. If each month she spends 20% of her class time in tap class, what is the total number of hours she spends in dance classes each month? Show your work or explain how you found your answer in complete sentences.
Answer:
20 hours
Step-by-step explanation:
20 hours, since you have to find the remaining 80% of her dance time.
I thought of this as follows:
1/5 = 4
2/5 = 8
3/5 = 12
4/5 = 16
5/5 (100% of her dance time!) = 20 hours!
I hope this helped a bunch! Tell me if you need any further assistance...

Can someone solve this for me plis
Answer:
x = 1
Step-by-step explanation:
Here is what you need to know:
f(x) represents the y-value.
The x in the parenthesis represents the x-value.
Another way to write f(x) = 1 is y = 1.
So now you are just finding the x-value for when y = 1. Looking at the graph, when y is 1 ( 1 on the y-axis), x has to be 1! This is because when you go up one, the only value that matches that point is 1!
Hope this helps :)

What percent of the students prefer superhero movies? Round your answer to the nearest whole number percent.
Answer:
36%
Step-by-step explanation:
47/132=36%
The = is means the equal sign with the ~ position
The percent of the students prefer superhero movies rounded to the nearest percent is; 36%
How to work with percentages?The table of this random survey of students when seen online tells us that;
Total number of students that prefer super hero movies = 47
Total Number of Students that prefer Comedy = 50
Total Number of Students that prefer drama = 35
Thus;
Total number of students surveyed = 47 + 50 + 35

b) y=200(8)+450 = $2050
c) 21 months
Step-by-step explanation:
a) y=200x+450
200 per month plus her initial deposit of 450
b) y=200(8)+450 = 2050
To see how much she'll have after 8 months, plug in 8 for x
c) 4500<200x+450
4050<200x

Answer:
w = 28
x = 18
Step-by-step explanation:
To make the triangles congruent, the hypotenuse and leg need to be the same length.
5w +x -59 = -w +2x +91
4w+4x -92 = 2x +2w
These two equations can be written in general form by subtracting the right-side expression from both sides.
6w -x -150 = 0
2w +2x -92 = 0
The second of these equations can be divided by 2 to give ...
w +x -46 = 0
When that is added to the first equation, we have ...
7w -196 = 0
w -28 = 0
w = 28
Using this in our simplified second equation, we have ...
x = 46 -w = 46 -28
x = 18
_____
Additional comment
These values of w and x make the side lengths ...
UV = 2x -w +91 = 2(18) -28 +91 = 8 +91 = 99
UT = 2x +2w = 92 . . . . from 2nd equation
Using the Pythagorean theorem, this makes ...
TV = √(99^2 -92^2) = √1337 ≈ 36.57

Help me SalmonWorldTopper please please
Given info:- 5/(x-3) - 4/(x+4) = 1/x. And here the problem has asked to find out the value of x ?
Let's solve!!
Given equation is 5/(x-3) - 4/(x+4) = 1/x
⇛ [5(x+4) - 4(x-3)]/(x-3)(x+4) = 1/x
⇛ (5x+20-4x+12)/(x-3)(x+4) = 1/x
⇛ (x+32)/(x-3)(x+4) = 1/x
On applying cross multiplication then
⇛ x(x+32) = (x-3)(x+4)
⇛ x²+32x = x(x+4)-3(x+4)
⇛ x²+32x = x²+4x-3x-12
⇛ x²+32x = x²+x-12
⇛ x²+32x-x²-x = -12
⇛ (x²-x²)+(32x-x) = -12
⇛ 0+31x = -12
⇛ 31x = -12
⇛ x = -12/31
∴ x = -12/31
The value of x for the given problem -12/31
VERIFICATION:
Check
If x = -12/31 then LHS of the equation is
5/(x-3) - 4/(x+4)
⇛ 5/[(-12/31)-3] -4/[(-12/31)+4]
⇛ 5/[(-12-93)/31] -4/[(-12+124)/31]
⇛ 5/(-105/31) - 4/(112)/31
⇛ (5×-31)/105 - (4×31)/112
⇛ (-115/105)-(124/112)
⇛ (-31/21) - (31/28)
⇛ (-31)[(1/21)+(1/28)]
⇛ (-31)(21+28)/(21×28)
⇛ (-31×49)/(21×28)
⇛ (-31×7)/(21×4)
⇛-31/12
And RHS = 1/x
⇛ 1/(-12/31)
⇛ -31/12
⇛ LHS = RHS is true for x = -31/12
Complete the proof that m∠QSR+m∠UVX=180°.
Answer:
Co - interior angles of a parallelogram add up to 180 degrees
Step-by-step explanation:
Since UW and RT are parallel lines we can infer that if the QSR was flipped and joined to UVX it would create a parallelogram. Angle theorem states that co -interior angles of a parallelogram add up to 180 degrees.
Using properties of parallel line we can prove that
m ∠QSR + m ∠UVX =180°.
What parallel lines?Numerous pairs of angles are created when a transversal line intersects any two parallel lines. While some angles are complementary, others are congruent (equal).
Properties of Parallel Lines
The fundamental characteristics listed below make it simple to recognize parallel lines.
Straight lines that are always the same distance away from one another are called parallel lines.No matter how far apart they are from one another, parallel lines can never intersect.Given:
We have to prove that m ∠QSR+ m ∠UVX=180°.
Now, using parallel line property
<QSR = <SUV ( corresponding angle).........(1)
and, <SVU + <UVX = 180 (linear pair)
<QSR + <UVX = 180 ( from (1))

Use the image to the right to determine how tall the tree is . The hypotenuse is 7.5m and the leg is 6.2m
Answer:
4.22m.
Step-by-step explanation:
Using Pythagoras theorem:
7.5^2 = h^2 + 6.2^2
h^2 = 7.5^2 - 6.2^2
h^2 = 17.81
Height h= 4.22.
The cost for 4 hamburgers and 3 drinks is $14.75. The cost for 5 hamburgers and 4 drinks is $18.75. How much does 1 hamburger cost.
Answer:
each hamburger is $2.75
Step-by-step explanation:
We can solve for this system of equations where x are the burgers, and y are the drinks:
4x+3y=$14.75
5x+4y=$18.75
We need to multiply the first row by 4, and multiply the second row by -3 to be able to solve for x
Multiplying, we get:
16x+12y=$59
-15x-12y=$56.25
Now subtracting the top by the bottom, we are left with:
x=$2.75
Thus, each hamburger cost $2.75
side note, you can plug in x=$2.75 into either equation and solve for y to figure out what each drink costs :)
