You are measuring the height of a lamppost. You stand 40 inches from the baseof the lamppost. You measure the angle of elevation from the ground to the top!
of the lamppost to be 70°. Find the height h of the lamppost to the nearest inch.

Answers

Answer 1
Answer:

Answer:

110in

Step-by-step explanation:

The horizontal distance from where you stand to the lamp post is 40 inches.

Let the height of the lamp post be y inches.

The angle of elevation from the ground to the top!

of the lamppost to be 70°.

The height , y and the horizontal distance, form the legs of a right triangle .

We can use the tangent ratio, to calculate the height of the lamp post .

\tan(70 \degree) = (y)/(40)

y = 40 \tan(70)

y = 109.9

To the nearest inch, the height is 110 inches

Answers

ANSWER: C.  alternate exterior

EXPLANATION: Alternate Exterior Angles are two angles that are on the exterior of and , but on opposite sides of the transversal. They are located outside the two parallel lines but on opposite sides of the transversal, creating two pairs of alternate exterior angles. Alternate exterior angles are congruent, meaning they have same measures. Here is an image to understand it better.

Hi there! :) I believe the answer is B: 1/8. The reason I picked 1/8 is because you add all the numbers together, so since we have 5,9, and 2 ; 5+2+9=16.
 So since it says what is the probability that the marble will red. There are 2 red marbles so it would 2/16 but there is NO 2/16 so we simplify. 2/2=1 and 16/2= 8 So your answer is 1/8! Hope I helped :) :D  Have a amazing day! ;)
Hai, Brainiac!

Great question!

Basically to find the answer, first you add the number of each marble there is.

5 black marbles + 9 white marbles + 2 red marbles = 16 marbles altogether.

Red marbles to the total number of marbles altogether is 2:16, a ratio.

Simplified, that would be 1:8 marbles, or, answer choice B, so your answer would be 1/8 :D

Hope this helps!

Which value is equivalent to the expression 4 (little 5)?

Answers

the little 5 is an index, sometimes known as a power. to use it we do:
4x4=16
16x4=64
64x4=256
256x4=1024

so the answer is 1024

i hope that makes sense to you, if it doesn't just let me know :)

The capacity of a beaker is 0.1 liter converted to millimeter

Answers

One liter is equal to 1000 milliliters ("milli" comes from Latin, and it's a form of the word thousand: mille. )

so 0.1 liter is 0.1*1000=100

so 0.1 liter is 100 milliliters!
