What number went in?
Answer:
47.5
Step-by-step explanation:
47.5=100%
57=120%
The input value is 47.5 when the output is 57.
What is division?The division in mathematics is one kind of operation. In this process, we split the expressions or numbers into the same number of parts.
Given:
When the output is 120%, the input is 100%.
And the output is 1.2 times the input.
So, we have the output 57.
To find the input number:
Use division process,
The required number = 57 /1.2
The required number = 47.5.
Therefore, the number is 47.5.

2x-xy=3
-xy=3-2x
y=3-2x/x
Answer:
[tex]y = - \frac{3}{ x} + 2[/tex]
Step-by-step explanation:
So we want y to be on a side by itself.
2x-xy=3
Subtract 2x from each side
-xy=3-2x
divide each side by -x

how many solutions does the system of equations have?(1 point)
3x=-12y+15 and x+4y=5
A-one
B-two
C-infinitely many
D-none
Answer:
c
Step-by-step explanation:
First, I'll isolate the x in x+4y=5 to match with the other equation.
The new equation would be x= -4y+5
Next, we will multiply one equation by 3 and the other by -1 for both to match with the other.
-1(-12y + 15 = 3x )
3(-4y + 5 = x)
The new equations would be :
12y - 15 = -3x
-12y + 15 = 3x
Add the equations and you get
0 = 0
The equation has an infinite amount of solutions

The planet mercury makes its circuit around the sun in 88 days. Venus takes 225 days to complete it's circuit. Venus's travel time is what percent of Mercury's travel time?
Answer:
255.682%
Step-by-step explanation:
From the above question:
The planet mercury makes its circuit around the sun in 88 days.
Venus takes 225 days to complete it's circuit.
Venus's travel time is what percent of Mercury's travel time?
This is calculated as:
(Number of days Mercury take to complete it's circuit/Number of days Venus takes to complete it's circuit) × 100
= 225/88 × 100
= 2.5568181818181817 × 100
= 255.68181818%
Approximately = 255.682%
Venus's travel time is 255.682 percent of Mercury's travel time

Answer:
y = 5/4x + 10
Step-by-step explanation:
First, we need to use point-slope form which is:
y - y₁ = m(x - x₁)
Now, we substitute the numbers:
y - 5 = 5/4(x - (-4))
y - 5 = 5/4(x + 4)
y - 5 = 5/4x + 5
y = 5/4x + 10
You can check by substituting the points into the equation:
5 = 5/4(-4) + 10
5 = -5 + 10
5 = 5

Answer:
3 hours and 40 minutes I think
Step-by-step explanation:
Answer:
3 hours and 40 mins
Step-by-step explanation
First, you check 3 hours times 50 miles and 3 hours times 60 miles to get how close they are. 3x50=150, and 3x60=180. 150+180=330. Then you multiply 4/6 or 2/3 by 5 and 6 then add them (because 40 mins is 2/3 of an hour) 50x2/3/2=100/3 and 60x2/3=120/3=40. 40+50/3=73 1/3. 73 1/3+330= 3 hours and 40 mins.

Answer:
O1: b) linear, proportional
O2: a) linear, non-proportional
O3: c) nonlinear
Step-by-step explanation:
Recall that a proportional function can be drawn as a straight line (linear function) through the origin (0,0).
O1 is a proportional function since it is linear and goes through the origin.
O2 has a y-intercept of y = 5; therefore, it is not proportional because it does not go through the origin (0,0), although it is linear.
O3 resembles a quadratic function, which means it's not a linear function (nonlinear).

Michael is buying new shirts and pants for school. He bought shirts for $38 each and pants for $38 each. He purchased nine items and spent a total of $222. How many shirts did he buy?
Answer:
No possible solution
Step-by-step explanation:
Let:
Shirt = x
Pant = y
x + y = 9 - - - - - - - - - (1)
38x + 38y = 222 - - - (2)
From (1):
y = 9 - x
Put y = 9 - x in (2)
38x + 38(9 - x) = 222
38x + 342 - 38x = 222
Based on the Given parameters, we can conclude that the equation does not have a possible solution.

A ball is thrown from a mountain 960 feet high, into the air with an upward velocity of 64 ft/s. When did the ball hit the
ground? And What was the max height it reached?
Answer:
The ball will hit the ground at 10 seconds and its maximum height is 1024 feet.
Step-by-step explanation:
Height of a mountain, h = 90 feet
Upward velocity of a ball, u = 64 ft/s
Its height as a function of time can be written by using the second equation of motion as follows :
[tex]f(x) = -16t^2 + 64t + 960[/tex] .....(1)
When it will hit the ground, f(x) = 0
[tex]-16t^2 + 64t + 960=0\\\\16(-t^2+4t+60)=0\\\\-t^2+4t+60=0[/tex]
It is quadratic equation.
t = -6 s and t = 10 s
Neglecting -6 seconds, the ball will hit the ground at 10 seconds.
For maximum height,
Put f'(x) = 0
[tex]-32t+64=0\\\\\\t=\dfrac{64}{32}\\\\t=2\ s[/tex]
Put t = 2 in equation (1)
[tex]f(2) = -16(2)^2 + 64(2) + 960\\\\=1024\ \text{feet}[/tex]
Hence, the ball will hit the ground at 10 seconds and its maximum height is 1024 feet.
