for all positive angles less than 360°, if csc csc (2x+30°)=cos cos (3y-15°), the sum of x and y is?
Answer:
35 degrees
Step-by-step explanation:
for all positive angles less than 360°, if csc (2x+30°)= cos (3y-15°), the sum of x and y is?
Let the given expression be equal to 1, hence;
csc (2x+30°)= cos (3y-15°) = 1
csc (2x+30°) = 1
1/sin(2x+30) = 1
1 = sin(2x+30)
sin(2x+30) = 1
2x+30 = arcsin(1)
2x+30 = 90
2x = 90-30
2x = 60
x = 60/2
x = 30 degrees
Get the value of y;
cos (3y-15°) = 1
3y - 15 = arccos (1)
3y - 15= 0
3y = 0+15
3y = 15
y = 15/3
y = 5
Sum of x and y;
x+y = 30 + 5
x+y = 35degrees
Hence the sum of x and y is 35 degrees

Out of 15,000 voters in a constituency, 60% voted. Find the percentage of voters who did not vote. Can you now find how many actually did not vote?
Answer:
40 did not vote
6000 people did not vote
Step-by-step explanation:
1 % of 15,000 = 150
150 * 40 = 40% of 15,000 = 6000

Construct a scatter plot of the following given information showing the amount of time students spend doing homework per week and their overall GPA in school. Be sure to label the graph and answer any other questions.
Answer:
Please look at the graph attached to find the x axis and y axis...
a) it has a postive association (becuase of the increment of the trendline)
b) it is linear becuase it is increased from the 0 value and up)
c) there is a outlier in the graph as you can see about four hours the GPA increased by 3.2 then back to 2.5
Hope this helps!!!
find the value of X, please!
Answer:
x=42°
Step-by-step explanation:
We know that 2 of the legs are congruent, so the angles opposite them will be congruent.
The angles of a triangle add up to 180°
This can be represented by [tex]96+2x=180[/tex]
[tex]2x=84[/tex]
[tex]x=42[/tex]
Hope this helps :-)
Answer: 42 degrees
Step-by-step explanation: Since this is an isosceles triangle, your remaining two angles will be equal
There are 180 degrees in any triangle
Since you have already used 96 degrees, you must subtract to find what is remaining
180-96=84
Since your remaining two angles are equal, you can half 84 to find your answer
84/2=42
Both x and your one remaining angle should be 42
X=42
HELP PLEASE!!!! math questions:
1. Fill in the blanks to describe how you could identify the number of solutions to a system if you only
knew some points on each line.
Start by finding the _______________ of each line using the points.
Compare the slopes. If they are different, the lines _______________. This means there is
_______________ solution to the system.
You could also plot the points on a _______________ and use this to find the point where the
lines_______________.
2. . Identify the number of solutions from the description of the equations.
Two equations are the same on one side but different on the other. ANSWER:
One of the equations in the system can be rewritten so it is identical to the other equation.ANSWER:
3.Adding the equations in a system of equations can sometimes be helpful in solving a system of

Kiran is playing a video game. He earns 3 stars for each easy level he completes and 5 stars for each difficult level he completes. He completes more than 20 levels total and earns 80 or more stars
Answer:
10 easy levels and 10 difficult levels
Step-by-step explanation:
Given data
let the number of easy levels be x
and the number of difficult levels be y
so
x+y= 20----------1
and
3x+5y= 80------2
from 1
x=20-y
put this in 2
3(20-y)+5y= 80
60-3y+5y=80
2y=80-60
2y=20
y= 20/2
y= 10
put y= 10 in 1
x+10=20
x=20-10
x= 10
Hence Kiran played 10 easy levels and 10 difficult levels

Janice NEEDS 3 GALLONS of lemonade for a party. She has 4 quarts, 6 pints and 4 cups of lemonade already made. How many CUPS of lemonade does Janice have? Be sure to re-state the question when giving your answer.
Answer:
32 cups
Step-by-step explanation:
To find the total number of cups, we have to convert the measures that are not in cups to cups and add
1 quart = 4 cups
4 quarts = 4 x4 = 16 cups
1 pint = 2 cups
6 pints = 2 x 6 = 12 pints
total number of cups = 16 + 12 + 4 = 32 cups
When you flip a biased coin the probability of getting a tail is 0.2.
How many times would you expect to get tails if you flip the coin 240 times?
Answer:
48
Step-by-step explanation:
Multiply 0.2 × 240 = 48.
It's a very biased coin, so the outcome will be considerably less than the 120 we would expect from a fair coin.
