The space shuttle travels at 28000 mph while orbiting the earth. How far does the shuttle travel in feet per day
STatiana [176]

We are given the speed of the shuttle as:

speed = 28,000 miles / hour

 

We know that:

1 mile = 5280 ft

24 hour = 1 day

 

Therefore by conversion:

speed = (28,000 miles / hr) * (5280 ft / 1 mile) * (24 hr / day)

speed = 3,548,160,000 ft / day

 

In 2 significant figures:

<span>speed = 3.5 x 10^9 ft / day</span>

Evaluate 3(a + b + c)2 for a = 2, b = 3, and c = 4
Verdich [7]

Answer: 243

Step-by-step explanation:

We have the expression

3(a + b + c)^2

Note that the expression depends on 3 variables

a, b and c

in this case we want to evaluate the expression for

a = 2\\b = 3\\c = 4

Then change the variable a by the number 2, the variable b by the number 3 and the variable c by the number 4

So we have

3(2 + 3 + 4)^2

Now simplify the expression

3(9)^2

3*81=243

The answer is 243

What is the length of in the right triangle below? A. B. 24 C. 576 D. 36 E. 16 F. 260
harina [27]

Answer:

B. 24

Step-by-step explanation:

To find this, use Pythagorean Theorem

a^2+b^2=c^2

a is 10, and c is 26. We know 26 is the hypotenuse because it is opposite the right angle

10^2=b^2=26^2

100+b^2=676

Subtract 100 on both sides

b^2=576

Take the square root of both sides

b=24

Hope this helps! :)

The two hot-air balloons in the drawing are 48.2 and 61.0 m above the ground. A person in the left balloon observes that the rig
serious [3.7K]

The horizontal distance between the two balloons is 53.8 meters.

<u><em>Explanation</em></u>

According to the below diagram, A and B are the positions of two balloons which are 48.2 meter and 61.0 meter above the ground respectively.

Horizontal distance between two balloons is AC, which is x meter.

A person in the left balloon observes that the right balloon is 13.38° above the horizontal. That means, ∠BAC = 13.38°

According to the diagram,  BC= 61.0-48.2 = 12.8 meter

Now in right angle triangle ABC.....

tan(13.38)=\frac{BC}{AC}\\ \\ tan(13.38)= \frac{12.8}{x} \\ \\ x= \frac{12.8}{tan(13.38)}=53.8

So, the horizontal distance between the two balloons is 53.8 meters.
