Consider the cross-sectional right triangle shown in the figure.
One of its sides is the height of the pyramid, with length H. The other side is half of the square base, so its length is 81 m. The hypotenuse of this triangle is the height of one of the faces.
By right triangle trigonometry,
,
thus,
.
Answer: C) 52 m
In the question, there are two people with different percentage of drinking water from different quantities.
Taking the first case of Kylie we get that he drank 35% water of 400ml
Then
35% of 400 ml = (35/100) * 400 ml
= (35 * 4) ml
= 140 ml
So Kylie drank a total of 140 ml water.
Now taking the case of Eugenia we get that he drank 45% of 350 ml water.
Then
45% of 350 ml = (45/100) * 350
= 1575/10 ml
= 157.5 ml
So Eugenia drank 157.5 ml of water. Then we can conclude that Eugenia drank more water than Kylie.
You would want to add all of the angles together to find the sum. Set this equal to 360.
2x-9 + 2x-9 + x + x + x = 360
Combine like terms,
7x-18 = 360
Add 18 to both sides,
7x = 378
Divvied both sides by 7,
x = 54
Answer:30/4
Step-by-step explanation:180-11x+5, add all up=180, you get 30/4

Answer:
"4.71" is the correct answer.
Step-by-step explanation:
As we know, 45 envelopes addressed in 2 hours then,
⇒ 
and, 45 in 3 hours,
⇒ 
Now by adding all together, we get
⇒ 
⇒ 
and multiply it by "4.71", we get
⇒ 
⇒ 
Round it "310".
So that "4.71" is the right answer.
