Answer:

B

Step-by-step explanation:

sine = opposite/hypotenuse

sin45 = x/4

sin45/1 = x/4

cross multiply

1 × x = 4 × sin45

x = 4sin45

x = 2.828427125

x = 2 × square root of 2 = 2.828427125

Answer:

B )  2\sqrt{2}

Steps:

α = 90°, β = 45°, a = 4: b = 2.82842. . .

β = 45°

a = 4

α = 90°

b =  \frac{4sin(45)}{sin(90)}

b = 2.82842. . .

2\sqrt{2} = 2.82842. . .

At the playground, 60% of the bike rack was filled. Thisis 30 bikes. How many total slots are there for bicycles?
Blizzard [7]
The most simplest way to explain this is by breaking down the 60%.

Think about it.

If 60% space = 30 bikes

then 30% space = 15 bikes

then 10% space must be 5 bikes.

So we now know for sure 60% space = 30 bikes.
And 10% space = 5 bikes.

Then we know remaining 40% space = 20 bikes.

So total space = 100% space, for 50 bikes.

This is the question of ratio, it is the quantitative relationship of two number.

In this survey a ratio of 66 people out of 110 is defined as living in apartment, based on this ratio we can estimate the total numbers of people living in apartments.

Total population of the town = 25,000 people

Ratio of people living in apartment = 66 / 110 = 0.6

Town people living in apartment = 25,000 x 0.6 = 15,000 peoples
