The complete question in the attached figure

we know that

(35)/(40.5+54)=x/54-------- > (35)/(94.5)=x/54---------> x=(54)*(35)/(94.5)

X=20 ft

the answer is 20 ft

Answer:

The height of the platform is 20 ft

Step-by-step explanation:

In the figure attached, the problem is shown.

Let's call α to the angle opposite to the 35 ft side. From sine definition:

sin α = opposite/hypotenuse

Taking into consideration both, major and minor triangles:

sin α = 35/(40.5 + 54) = x/54

where x can be isolated, as follows:

x = 35/(40.5 + 54) * 54 = 20 ft

The number of small lawns Isabella can rake depends on the amount of time she spends raking. Isabella can rake 3 lawns in 3.75 h

ycow [4]

Answer:

1) 4 2)7

Step-by-step explanation:

1) If we divide 3.75/3=1.25 which is the amount of time she takes per yard so if we add another yard to what she has already done we find she only could do one more yard in 5 hours 3.75+1.25=5.00 So she can only rake 4 yards in 5 hours

2) If we divide 20.25/3=6.75 we find that each ticket is $6.75 so we must divide that by 47.25 to get the amount of tickets 47.25/6.75=7

The internet was used by 30% of the population of a state in 2008. If 3200 people were surveyed, how many in the survey were usi

andrew-mc [135]

1. We know that 30% expressed as a decimal is 0.30

Since 30% of people were using the internet, 0.30*3200 is our answer.
3200*0.30= 960.

Therefore 960 people were using the internet out of the 3200 surveyed.
