Didn’t get the full problem, what is z equal to?
3/8 of the mixture is white; 5/8 is black. Then for 2 gallons of mixture,
.. (3/8)*2 gal = 3/4 gal
of white paint are needed, and
.. (5/8)*2 gal = 5/4 gal
of black paint are needed.
Rounding up to the nearest 1/2 gallon,
.. 1 gallon of white and 1 1/2 gallons of black must be purchased, for a total of 2 1/2 gallons of paint.
Answer:
X= 10
Step-by-step explanation:
let the vertex of angle 17° named A
then the other two B and C
then by using trigonometry:
sin(A) = opposite side divided by hypotenuse
opposite side is. X
Wich makes Sin(A) = X/47
then by crossing X= sin(A) × 47 = 13.74147
rounding to the nearest tenth: X= 10
