Please help! I do not know how to find the unknown variables using the Pythagorean theorem. Any help will be greatly appreciated:))
Answers
Answer:
x=10.247
y=52.02
z=37.98
Step-by-step explanation:
For x you use Pythagorean theorem which, in this situation would be 13^2=8^2+x^2 rearranging this we can figure out x by taking the square root of 13^2-8^2.
For y you can use any trig function but I chose to use cos since that uses info we're given, to find y you just do the inverse cos or cos^-1 of 8/13 to find the angle
For z you can use any trig function but I chose to use sin since that uses info we're given, to find z you just do the inverse sin or sin^-1 of 8/13 to find the angle

Answers
Answer:
Step-by-step explanation:

A unit rate is a rate with 1 in the denominator. If you have a rate, such as price per some number of items, and the quantity in the denominator is not 1, you can calculate unit rate or price per unit by completing the division operation: numerator divided by denominator.

Step-by-step explanation:
since they are in order points p and q are in the middle and points O and R are on the end so they say that OR=36 since you don't know the exact lengths of all of the lengths in the middle from O to R then you multiply 5,6 and 1 by x and add
5x+6x+1x=12x
so then the whole length is equal to the ratio of 12x and also 36 so set those to equal each other
12x=36
x=3
so that is just the ratio and since they are asking for the length of O to Q that means that it is just 5x+6x=OQ
11x=OQ
insert x=3
33=OQ

If the simple interest on $7,000 for 2 years is 980, then what is the interest rate?
Answers
Answer:
7%
Step-by-step explanation:
since the formula says si=ptr/100
so we have to separate r which gives us r =(i ×100)/(p×t)
now putting the values (980×100)/(7000×2)
=7
therefore the rate of interest is 7%

Simplify your answer and write it as a proper fraction, mixed number, or whole number.
Answers
Answer:
$16
Step-by-step explanation:
$4 for 1/4 of a pie, means that it isn't an entire pie. Luckily for us, this is simple multiplication. You would multiply like so:
4 x 4 = 16
And you'd get your answer, since 4/4 equals 1 whole.

The tape diagram represents an equation
Answers
Answer:
H=16
Step-by-step explanation:
To find the answer, first look at the boxes. They are both the same length (drawn to scale), so you’ll need to find the missing length of h. H and 26 would need to equal 42, since they are both the same length.
Now, figure 42 - 26, and that’s 16.
Therefore h = 16.
