The seventh grade class is raising money to have a class trip at the end of the year. They began the year with $1500. They now have $1650 in the account. What is the percent of increase for the money the class has raised ?
Answer:
The percent of the increase for the money the class raised is 10 %
Step-by-step explanation:
Because if you divide 1500 by 10 you get 150 that means 150 is 10 % of 1500 and if you add 150 to 1500 you get 1650 so the increase of money the class raised is 10 %

A leaking faucet drips into a bucket. The faucet drips at a constant rate. The level of water in the bucket rises
3 inches in 6 hours. What was the rate per hour of the water level change?
Answer:
The per hour rate is 0.5 inches per hour
Step-by-step explanation:
Here, we want to calculate the rate at which the level of the water increased
Mathematically, we can get this by dividing the amount of increment by the time it took
That would be 3 inches divided by 6 hours
= 3/6 = 0.5 inches per hour
Molly is currently one third the age of her mother. In 12 years, Molly will be half the age that her mother will be. How old is Molly's mother now?

There are 3 teachers to 125 pupils during the school program. How many teachers were
there if there were 2 500 pupils
Answer:
There were 60 teachers.
Step-by-step explanation:
☆We can use proportion to solve this!
[tex] \frac{3 \: teachers}{125 \: pupils} = \frac{x}{2500 \: pupils} \\ \\ \frac{125x}{125} = \frac{7500}{125} \\ \\ x = 60[/tex]
list the integers that satisfy both these inequalities, 2x+9 -12
Answer:
x < -10.5
Step-by-step explanation:
list the integers that satisfy both these inequalities, 2x+9 <-12
Subtract 9 from both sides;
2x +9 - 9 < -12-9
2x < -21
x < -21/2
x < -10.5
Hence all the integers are values of x less than 10.5

The cost of a mobile phone processor is directly proportional to its speed.
A 2GHz mobile costs £500.
Let x be the speed of a processor in GHz
Let y be the cost in pounds.
Find a formula linking the variables.
Answer: See explanation
Step-by-step explanation:
We are going to use the formula used in calculating direct proportion which is equal to:
y = kx
where,
x = speed of a processor in GHz
y = the cost in pounds
Therefore, y = kx
500 = 2k
Therefore, y = 2k

Foster’s answer to the question he wrote for Ranger was 7x+(-3), while Ranger’s answer was 7x-3.They both checked their work by letting x=5, and they both claim to be correct.Are they both correct?Explain.
Answer: They are both correct :)
Step-by-step explanation:
They are both correct because 7x + (-3) is the same thing as 7x - 3 if you simplify it.
When you simplify it, you change the expression to:
7x + 1 (-3)
So now you have to distribute the 1 which gives you:
7x - 3
..since positive x negative is negative.

Slope = (6-3)/(2-1) =3
Please help!!!!!! Thank you!
Answer:
y= -4/3x+8
Step-by-step explanation:
y=mx+b is the equation for a line
m=slope
b=y-intercept
First, find the slope
The formula for the slope is: y2-y1/x2-x1
8-0/0-6=
8/-6=4/-3
Plug the slope into the equation
y= -4/3x+b
Now find the y-intercept.
To do this, plug in the x and y of a coordinate and solve for b
I will use (0,8)
8= -4/3(0)+b
8=b
Plug the y-intercept into the equation
y= -4/3x+8
y= -4/3x+8 is your equation

Answer: 81 yrs
Step-by-step explanation: a stands for Ashley, c stands for Colleen
2c + 3a = 108
c = 3a
3a + a = 108
4a = 108
a = 27
c = 3a
c = 3 (27)
c = 81

Answer:
[tex]Area = 34.2cm^2[/tex]
Step-by-step explanation:
Let the three sides be a, b and c respectively.
Such that:
[tex]a = 8[/tex]
[tex]b = 9[/tex]
[tex]c= 10[/tex]
Required
Determine the area
This is calculated as:
[tex]Area = \sqrt{s(s-a)(s-b)(s-c)[/tex]
Where
[tex]s = \frac{1}{2}(a + b + c)[/tex]
Substitute values for a, b and c
[tex]s = \frac{1}{2}(8 + 9 + 10)[/tex]
[tex]s = \frac{1}{2}(27)[/tex]
[tex]s = 13.5[/tex]
Substitute values for a, b, c and s in
[tex]Area = \sqrt{s(s-a)(s-b)(s-c)[/tex]
[tex]Area = \sqrt{13.5 * (13.5 - 8)* (13.5 - 9)* (13.5 - 10)[/tex]
[tex]Area = \sqrt{13.5 * 5.5* 4.5* 3.5[/tex]
[tex]Area = \sqrt{1169.4375[/tex]
[tex]Area = 34.2[/tex] -- Approximated
