Answer:
800 students total
Step-by-step explanation:
75% is the same as 3/4, so if you divide 600 by 3 you get 200. Then, you add that back into the number you just divided to the full 100% which is 800.

Answer:
Y = theta = 32.68
Step-by-step explanation:
Formula
y^2 = x^2 + z^2 - 2*x*z * cos(theta)
Givens
y = 55
theta = ?
z = 50
x = 90
Solution
55^2 = 90^2 + 50^2 - 2*90*50 cos(theta)
3025 = 8100 + 2500 - 9000 cos(theta) Combine the right
3025 = 10600 - 9000 Cos(theta) Subtract 10600
3025 - 10600 = -9000 Cos(theta)
-7575 = - 9000 Cos(theta) Divide by - 9000
-7575/-9000 = cos(theta)
0.8417 = cos(theta)
cos-1(0.8417) = theta
theta = 32.68

Next month, Noelle will earn a 15% increase in her hourly wage. If she currently earns $12 an hour, what will her new hourly wage be after her raise?
Show your work in one or more of the spaces, then answer here:
Answer:
Her new hourly wage will be $13.80 after the raise
Step-by-step explanation:
Percentages
Noelle currently earns $12 per hour.
Her hourly wage will increase by 15% by next month.
The increase will be of:
15% of $12 = 15*12/100 = $1.80
Thus, her new hourly wage will be
$12 + $1.80 = $13.80
Her new hourly wage will be $13.80 after the raise

If you rewrote these percents as fractions which one could be written as a whole number over 10? A. 1% B. 5% C.25% D. 40%
Answer:
D. 40%
Step-by-step explanation:
Hi! All you basically need to do in this question is to really think. The tenths placement is what you are looking for.
Let us use money for example. a penny would represent 1%. It needs to be in tenths, 1/10, 2/10, 3/10, and so on to be a whole number. A penny is simplified to be only 1/100. This will not work.
B is 5%. This would represent a nickel. A nickel is simplified to be 1/20. This will not work. C is 25%. This would represent a quarter.
A quarter simplified is 2.5/10... not a whole number.
However 40% is 4/10, making it our answer.
Hope this helps!

Scientists study ways to increase the population
of wild salmon. How many salmon eggs may be
needed to produce 16 adult salmon?
For every 8,000
eggs, only 2.
adults may
survive.
Answer:
64 000
Step-by-step explanation:
2 survive for every 8 000.
We have 2 x 8 = 16
=> For 8 000 x 8 = 64 000 salmon eggs, 16 may survive.
12 1/2 - 9 1/4= What is the answer to this question?
Answer:
3 1/4
Step-by-step explanation:
First you would convert them to improper fractions with common denominators.
12 1/2 >>>> 25/2
9 1/4 >>>>>> 37/4
to get a common denominator, you would multiply 25/2 by 1/2 to get 50/4.
50 - 37 = 13
so your answer would be 13/4

Answer:
192.
Step-by-step explanation:
Since it is length x width x height, I would do 6 x 2 first since that's easier. So, 16 x 12 is 192.
What type of slope is shown in the graph?
negative
positive
undefined
zero
Answer:
undefined
Step-by-step explanation:
For each part, write the equation that represents the line in slope-intercept form (y = mx + b) and standard form (ax + by = c where a, b, and c are integers and a is not negative).
Answer:
Graph
[tex]y = -x+1[/tex] --- Slope intercept form
[tex]y +x= 1[/tex] --- Standard form
Points
[tex]y = 2x-2[/tex] --- Slope intercept form
[tex]y -2x=-2[/tex] --- Standard form
Step-by-step explanation:
Solving (a): The graph.
From the graph, we have:
[tex](x_1,y_1) = (1,0)[/tex]
[tex](x_2,y_2) = (0,1)[/tex]
First, calculate the slope
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
This gives:
[tex]m = \frac{1 - 0}{0 - 1}[/tex]
[tex]m = \frac{1 }{- 1}[/tex]
[tex]m = -1[/tex]
The slope intercept equation is:
[tex]y = m(x-x_1)+y_1[/tex]
So, we have:
[tex]y = -1(x-1)+0[/tex]
[tex]y = -1(x-1)[/tex]
[tex]y = -x+1[/tex]
In standard form:
[tex]y = -x+1[/tex]
Add x to both sides
[tex]y +x= x-x+1[/tex]
[tex]y +x= 1[/tex]
Solving (b): The points
From the graph, we have:
[tex](x_1,y_1) = (0,-2)[/tex]
[tex](x_2,y_2) = (3,4)[/tex]
First, calculate the slope
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
This gives:
[tex]m = \frac{4 - (-2)}{3 - 0}[/tex]
[tex]m = \frac{6}{3}[/tex]
[tex]m=2[/tex]
The slope intercept equation is:
[tex]y = m(x-x_1)+y_1[/tex]
So, we have:
[tex]y = 2(x-0)-2[/tex]
[tex]y = 2(x)-2[/tex]
[tex]y = 2x-2[/tex]
In standard form:
[tex]y = 2x-2[/tex]
Subtract 2x from both sides
[tex]y -2x= 2x-2x-2[/tex]
[tex]y -2x=-2[/tex]
