The answer would have to be 52/87. Since it says "given", as in a geometric sense (proof), you know that the overall would have to be 87. It also adds that the students would be in the 10th grade, thus bringing us to the conclusion that 52/87 is correct. Then, simply use a calculator and put in 52/87. You're final answer, rounded to the nearest hundredth, should be 0.60.

Building A is 400 feet tall and Building B is 300 feet tall. Johnny is standing in between the two building. The angle of elevat

Free_Kalibri [48]

Answer:

389 feets apart

Step-by-step explanation:

Given that:

Building A

Height = 400feets

Angle of elevation = 70°

Building B:

Height = 300 feets

Angle of elevation = 52°

Distance from the foot of building A to where Jonny is standing = x (see attached picture)

Using trigonometry :

Tanθ = opposite / Adjacent

Tan 70 = 400/ x

2.7474774x = 400

x = 145.58809 feets

Distance from the foot of building B to where Jonny is standing = y (see attached picture)

Using trigonometry :

Tanθ = opposite / Adjacent

Tan 52 = 300/ y

1.2799416y = 300

y = 145.59

y = 234.38568 feets

x + y = distance between the two buildings

(145.58809 + 234.38568) feets

= 379.97377

= 380 feets apart

A cylinder has a diameter of 6 ft and height of 9 ft. What is the volume of this cylinder?

Setler79 [48]

First, you've got to figure out the value of the radius so divide the diameter by two. Then, you'll want to find the area of the base or pi times radius squared.
(3.14x3^2)x9=V
After doing the math your answer comes out to 254.34 cubic feet or feet^3

PLEASE HELP I DONT UNDERSTAND AND NOBODY WILL HELP ME

Dima020 [189]

Answer:

radius=3

Step-by-step explanation:

volumes of a cone = 1/3πr²h

12π = 1/3× π × r² × 4

37.7 = 12.6r²/3

cross multiply

37.7×3=12.6r²

113.1=12.6r²

make r² subject of the formula

r²=113.1÷12.6

r²=8.976

r=√8.976

r=2.996

r=3.0 (to the nearest tenth)

Which equation represent the nth term of the arithmetic sequence?

ICE Princess25 [194]

Answer:

Step-by-step explanation:

The equation of the nth term of the arithmetic sequence is: $a_n =a_1+d(n-1)$

d = 9 - 4 = 5

a₁ = -6

Therefore:

$a_n =-6+5(n-1)\\\\a_n =-6+5n-5\\\\a_n =5n-11$
