Answer: $80
Step-by-step explanation:
You have been told that Sarah ended up paying $60, and you were told before that the charge for a lost book was 75%.
Therefore
$60 = 75%
Now we have to find out what amount of money would be equivalent to 100%:
To do this, find out what amount of money would be equivalent to 25% first.
You can do this by dividing both values by 3.
60 / 3 = 20
75 / 3 = 25
So now $20 = 25%
Now find 100% (which is the original amount) multiply each value by 4 :
$80 = 100%
So the school payed $80 for the book.
hope this helps :)
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

URGENT!!! PLEASE HELP!! two cars leave at the same time from two cities that are 374 miles apart and travel towards each other. Car 1 travels 50 mph and Car 2 travels 60mph. How long do they travel before they meet?
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:
Sqaure root of 3 divided by 2
Step-by-step explanation:
The value of function sin 60° is √3/2.
What is Trigonometry?Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.
We need to find the value of sin 60°
Sin 60 degrees is nothing but sin π/3
The sine function we obtain by dividing the opposite side by hypotenuse.
sin theta = Opposite side/ hypotenuse
sin 60=√3/2
The value of sin 60 degrees is square root of three by two.
Hence, the value of function sin 60° is √3/2.

Solve the literal equation for y.
2x – xy = 3
Answer:
Step-by-step explanation:
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
[tex]y = \frac{3}{ - x} + 2[/tex]

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
