Answer:

D = 35.8 degrees

Step-by-step explanation:

In this question, we are asked to use calculator to estimate the approximate measure of angle D given its tan value.

From the question, what we have is;

tan D = 0.72

Now to calculate the acute angle D, we will divide through by tan

hence,

D = tan^-1 0.72

or more simply tan^-1 can be called arc tan

Thus, D = arc tan 0.72

D = 35.75

D = 35.8 to the nearest tenth of a degree

Two trains leave towns 474 kilometers apart at the same time and travel toward each other. One train travels13 km/m faster than
guajiro [1.7K]

Answer:

112 km/h

125 km/hr

Step-by-step explanation:

Distance = time * speed

Distance  = distance train 1 + distance train 2

474 = 2(s) + 2(s + 13)

Distribute

474 = 2s + 2s + 26

Combine like terms

474 = 4s + 26

Subtract 26 from both sides

448 = 4s

Divide both sides by 4

112 = s

s = 112 km/h

s + 13 = 125 km/hr

Help on this thx for helping if you did
vichka [17]
To evaluate two fractions being divided, you must turn the right fraction into a reciprocal. That means you must put the bottom number at the top and then put the top number on the bottom (you’re basically switching them).

8/13 / 3/2

Now, once you turned the other number into a reciprocal, you multiply across. The top number times the other top number and do this to the bottom numbers, too.

8/13 * 3/2 = 24/26

You found the answer, 24/26. But as you can see, it’s not one of the choices. That’s because you need to simplify.

24/26 / 2/2 = 12/13

12/13 is your answer, or choice C!

I hope this helped. Comment below if you have any questions.

What is the volume of a sphere having a diameter of 6 cm?
leonid [27]

Answer:

113.1

Step-by-step explanation:

Volume of sphere = \frac{4}{3} × π × r²

Volume of sphere =  \frac{4}{3} × π × 3²

Volume of sphere =  \frac{4}{3} × π × 9

Volume of sphere =  \frac{4}{3} × 9 π

Volume of sphere = 113.1
