"The number was up by 6.5% on the 2010 number."
This means that the 2011 enrolment is greater than the 2010 enrolment.
Somethimes words can be difficult to get your head around.
My answer is not wrong.

inverse of x^(3/5) = x^(-3/5) OR 1/[x^(3/5)]
These two answers are just different ways of expressing the same thing.

13/9 divided by 3/19
take reciprocal (flip it) of second fraction and change divided by to multiply
13/9 * 19/3
multiply
=247/27 or as decimal (9.148)

2 1/2 * 3 1/4
multiply denominator (bottom number) with whole number(number on the side) and add numerator(number on the top) and put that number over the original denominator
5/2 * 13/2
multiply numerator with numerator and denominator with denominator
=65/8 or decimal (8.125) or mixed number (8 1/8)

8t + 5 = 6t + 1
-6t from both sides
2t + 5 = 1
-5 from both sides
2t = -4
divide 2 to both sides
t = -2

In 2011, the number of students that enrolled at a school was 965. The number was up by 6.5% on the 2010 number. How many students were at school in 2010. Please who all working thankyou
106.5% (of the 2010 enrolment) is 965 students
106.5% divided by 106.5 = 1%
so
1% must be 965 divided by 106.5 students
so
100% must be 965 divided by 106.5 *100 students
that is 965 / 106.5 * 100 students in 2010

Sine
-1
(0.96)
You are being asked for the inverse sine of 0.96
sometimes this is called arc sine 0.96
the answer will be an angle so you must make sure your calculator is in degrees or radian mode, whichever you want your answer in.
on some calcs you will enter
inv sin 0.96 =
on others I think it may be
asin 0.96 =
Really what it means is
If sin(theta)=0.96 Find theta
where
-90degrees <= theta <=+90degrees

I have a graphing problem that says 3x-y=1 I have the values for x but i don't know what y would be
okay, just say the values of x that you have are 0 and 2
When x = 0 you put 0 in for x and you get
3x-y=1
3*0 - y = 1
so
0 - y = 1
-y = 1
y = -1
So the point is x=0, y=-1 (0,-1)
When x=2 you substitute 2 for x and you get
3*2 - y = 1
6 - y = 1
-y = 1-6
-y = -5
y = 5
So the point is x=2, y=5 (2,5)
etc

it takes mrs brown 75 mins to get to work.at what ime must she leave home o arrive at work at 8.30 a.m.?
75 minutes is 1 hour and 15 minutes
8:30 - 1hour = 7:30
7:30 - 15 minutes = 7:15am

'mean' is another word for average.
so if you want to find the mean of a group of numbers you add them all up and then divide by how many there are.
for example
If the scores (numbers) are 2,3,8,5,9 then
mean = (2+3+8+5+9) / 5 = 27/5 = 5.4
The symbol for mean is an x with a bar (line) over the top.

pretty sure the answer is x^-5 since when numbers that are the same with different exponents are multiplied, you always add the exponents and -3 + -2 = -5

f(x)=f(x) => 32 = 5x - 3 => x = 7.

Expressing y in the term of x we get y = 3x - 1. Graphically it looks as the linear graph x inclined over Ox axis at an angle which slope coefficient is 3(i.e. the tangent of the angle is 3) and moved 1 unit down the Y.

The root of 28 is not to be found among set of integers, instead it can only be rearranged as it follows: sqrt(4*7)=
