Answer:
Step-by-step explanation:
For this exercise you need to use an Inverse Trigonometric Function called "Arctangent".
By definition:
You must observe carefully the triangle PQR shown in the picture attached.
In this case you can identify that:
Therefore, knowing those values you can substitute them into , as following:
Finally, evaluating, you get that the measure of the angle R is the following:
Rounding to the nearest tenth:
Answer:
y = 2/3
Step-by-step explanation:
14 = 6(2) + 3y
14 = 12 + 3y
2 = 3y
y = 2/3

Answer:
A) $157,555
Step-by-step explanation:
The sum of assets is ...
house + 2 cars = $280,000 +5,200 +15,600 = $300,800
The sum of liabilities is ...
mortgage +car loan +credit card +wedding
= $113,545 +9,200 +2,300 +18,200 = $143,245
The family's net worth is the difference between assets and liabilities:
$300,800 -143,245 = $157,555
Answer:
5:51 P.M.
Step-by-step explanation:
You first add 36 and 10 which you get 46 then add the 46 to the total so, 46 + 5 is 51 so she will get back at 5:51 P.M
So i’m not sure if there is a different way to do this but here’s how i did it:
start with 2:5
then just keep going up till you can add both numbers and get 28
so next i multiplied both sides by 2 to keep the ratio and got 4:10
then i went back and tried again and tried multiplying 3
which is 6:15.
that only is 21 students so it’s not right
next i tried 4
2 x 4 = 8
and
5 x 4 = 20
8:20 is still a 2:5 ratio and
8 + 20 = 28
so 8 students were in the teachers play
let me know if i can clarify anything
