Answer:
A. x = 11√3
B. y = 11
Step-by-step explanation:
A. Determination of the value of x.
Angle θ = 60°
Hypothenus = 22
Opposite = x =?
We can obtain the value of x by using sine ratio as illustrated below:
Sine θ = Opposite / Hypothenus
Sine 60 = x / 22
√3/2 = x / 22
Cross multiply
2 * x = 22√3
Divide both side by 2
x = (22√3) / 2
x = 11√3
B. Determination of the value of y.
Angle θ = 60°
Hypothenus = 22
Adjacent = y =?
We can obtain the value of y by using cosine ratio as illustrated below:
Cos θ = Adjacent / Hypothenus
Cos 60 = y / 22
½ = y / 22
Cross multiply
y = ½ × 22
y = 11
The area of Neil's rooms total
... (10 ft)×(10 ft) + (14 ft)×(14 ft) = 100 ft² +196 ft²
... = 296 ft²
Since Neil will save $1 per square foot by waiting on the sale, he will save
... (296 ft²)×($1/ft²) = $296

Answer:
girls to boys = 3 : 7
Step-by-step explanation:
girls to boys = 15 : 35
simplify by dividing with 5
girls to boys = 3 : 7
5/8 - 2/8, because you need common denominators, therefor the answer is -3/8
