There are several ways you can get it so I will give you guidelines to make it easier to find the answers using question 15 as an example.
You know one side and an angle and that the triangle has a right angle it.
If you are looking for a side opposite of your known angle and it is not the hypotenuse use: Tan^-1(angle)*known side, after that use pythagorus theorem. You can check if this is the right length by taking the sine of the unknown angle (90-known angle) This will get most of your problems except 18 and 19.
For 18 and 19, I would replace tan with the sin version. For 20, you can either work to have all of the digits on one side of the equation, or you can use the first equation after solving for the missing angle. I will double check my math when I am by a pad of paper to work it out, if you can reply with answers, I can compare to make sure they are right.

What would be the slope of a line that is perpendicular to the linear equation y = (-2/3)x +5?
Answers
Answer: The slope of a perpendicular line will be m = 3/2. To find the perpendicular gradient take the negative inverse of the original gradient.
Step-by-step explanation:
The slope of a perpendicular line will be m = 3/2. To find the perpendicular gradient take the negative inverse of the original gradient.
By 'negative inverse' I mean change the sign and switch the numerator and denominator (the top and bottom of the fraction).
The original gradient there is m = - 2/3. Remember the line equation: y = mx + c.
To gain the perpendicular gradient change the - to +, move the 3 to the top and the 2 to the bottom. Now m = + 3 / 2 = 3/2

A boat can go 756 miles on 63 gallons of gas. How far can it go on 53 gallons?
Answers
Answer: 636
Step-by-step explanation:
First, we need to find out how many miles per gallon (mpg) the boat gets
So we need to divide 756 by 63
756/63=12
Now we know the boat gets 12mpg
Now let's multiply 12 by 53
12x53
636 miles
A storage shed is a rectangular prism and has dimensions of 6 meters by 5 meters by 12 meters. If Jean were to double these dimensions, she believes she would only double the volume. Is she correct? Explain why or why not. Include a drawing in your explanation. HELP PLZ ILL GIVE 30 POINTS AND A MARK JUST PLZZZ :((((
Answers
Answer:
well lets double check
5 x 6 x 12 = 360 doubled would be 720
now lets double the dimensions
5 x 2 = 10, 6 x 2 = 12 12 x 2 = 24
10 x 12 x 24 = 2880
The answer is no, if you double the dimensions it doesn't mean your actual volume is doubled from the regular dimensions.

409 = 223 + z
409 = z + 223
409 - 223 = z + 223 - 223

A trader banks 250000frws at 9%per year compound interest rate calculated every 4 months. find the amount in the bank at the start of the year
Answers
Answer:
228,710.84 frws
Step-by-step explanation:
A trader banks 250000frws at 9%per year compound interest rate calculated every 4 months. find the amount in the bank at the start of the year?
The above question is asking us to find the Principal. The formula is given as:
P = A / (1 + r/n)^nt
A = Amount after time t = 250000
r = Interest rate = 9%
n = Compounding frequency = 4
t = time = 1 year
First, convert R as a percent to r as a decimal
r = R/100
r = 9/100
r = 0.09 per year,
Then, solve the equation for P
P = A / (1 + r/n)^nt
P = 250,000.00 / (1 + 0.09/4)^(4)(1)
P = 250,000.00 / (1 + 0.0225)^(4)
P = $228,710.84
The bank started with 228,710.84frws

Step-by-step explanation:
distributive property
Answer:
x = 18/45 (or, in a decimal, 0.4). Someone correct me if I'm wrong. :)
Step-by-step explanation:
We have to use the distributive property here. That means that you multiply -5x by 9 and -2 by 9. So...
9*-5x = -45x
9*-2 = -18
-45x = -18
Now, divide both sides by 45...
-45x/45 = -18/45
x = 18/45 should be the answer.

Last month, Kira spent 15 hours watching T.V. And 12 hours reading. During the same month, Charlie spent 20 hours watching T.V. And 16 hours reading. Who had a higher ratio of time spent watching T.V. To time spent reading? A. Kira B.Charlie C.Neither; the ratios are equivalent
Answers
Answer: C.Neither; the ratios are equivalent
Step-by-step explanation:
Kira spent 15 hours watching T.V and 12 hours reading. The ratio of time spent watching T.V. to time spent reading will be:
= 15/12
= 5/4
= 5:4
Charlie spent 20 hours watching T.V. and 16 hours reading. The ratio of time spent watching T.V. to time spent reading will be:
= 20/16
= 5/4
= 5:4
Therefore, they have equivalent ratio

The solution of a system of linear equations is where the two lines intersect....
True or False?!
Answers
Answer:
True
Step-by-step explanation:
The place where lines intersect is where the x and y values match up.
Just like this, if the lines do not intersect, there's no solution.
If the lines seem to be one line, there is all real number solutions.
Hope this helped!
Answer:
Step-by-step explanation:
True.
There is only 1 intersection point. That is the point where the x and y values are the same for both equations. For example if you have
y = 2x + 5 and
y = 3x + 2
The intersect point is (3,11). If you put 3 in each equation for x, they will return 11 for the y value.
I've included a graph to show you that this is true.
