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

Pls help asap!!!
Westkost [7]

Answer:

Step-by-step explanation:

Let x be the random variable. Since it is normally distributed and the population mean and population standard deviation are known, we would apply the formula,

z = (x - µ)/σ

Where

x = sample mean

µ = population mean

σ = standard deviation

From the information given,

µ = 474

σ = 32

x = 514

The probability of being below 514 is expressed as P(x < 514)

For x = 514,

z = (514 - 474)/32 = 1.25

Looking at the normal distribution table, the probability value corresponding to area below the z score is 0.89

Therefore,

P(x < 514) = 0.89

IceJOKER [234]
I’m assuming you mean to round to the nearest tenth? If so, it’s 79.3. If that’s not what you’re asking i don’t know what else you mean

Karl had planned to drive for 1023 hours on a certain day during his road trip. When he became sleepy, however, he decided to de
netineya [11]

Since Karl became sleepy and decided to decrease his driving time by 25%, he drove <u>767.25 hours</u> that day.

<h3>What is driving time?</h3>

Planned driving time is the estimated time that Karl planned to drive between two points or to one's destination.

The Actual driving time is the actual time that it took Karl to drive from one point to his destination.

Driving time can be estimated or calculated by dividing the distance by the speed.

<h3>Data and Calculations:</h3>

The planned driving hours on a certain day = 1,023 hours

Decrease in driving time = 25%

Percentage of hours Karl drove = 75% (100 - 25)

Hours drove that day = 767.25 hours (1,023 x 75%)

Thus, Karl drove <u>767.25 hours</u> that day.
