Answer:
Step-by-step explanation:
You would have 58 hours per day of work. We need to divide 720 by 58 in order to get your answer. Because 720 is 30 days times 24 hours.
Answer:
1-
sinA = perpendicular / hypotenuse
sinA = 40 / 50 OR 4/5
cosA = base / hypotenuse
cosA = 30 / 50 OR 3/5
ANS - OPTION(D) 4/5 , 3/5
2-
ANS - OPTION(C) √2 (You will need to learn the trigo angle tables for these questions)
3-
Using Pythagoras theorem-
15^2 = b^2 + 9^2
225 = b^2 + 81
b = √144
b = 12
OPTION(C) b = 12
4-
First we need to find the height of the triangle. To do that we need to take the triangle on the left and use cos30
cos30 = b / 6
√3/2 = b /6
3√3 = b
b = 3√3
and now we can use tan45
tan45 = 3√3 / x
1 = 3√3/x
x = 3√3
ANS - OPTION(A) 3√3
Hope this helps!!!
Answer:
The chances are very high because there are more nickels then there quarters, dimes, and pennies.
Step-by-step explanation:
length: m
less means "subtract", than means "reverse the order", triple means "times 3"
width: 3m - 5
Answer: 3m - 5
-3 = 5 - 4x
Add both sides by 4x
4x - 3 = 5
Add both sides by 3
4x = 8
Divide both sides by 4
x = 2
That's your answer. Have an awesome day! :)
