3. PR=51
4. FE=28
Step-by-step explanation:
3. since the two triangles are similar, set up a proportion:
x+8/3x-9=24/28
*cross multiply*:
28(x+8)=24(3x-9)
28x+224=72x-216
44x=440
x=20
to find PR:
PR=3x-9
PR=3(20)-9
PR=51
4. same here:
39/4x+2=42/5x-2
39(5x-2)=42(4x+2)
195x-78=168x+84
27x=162
x=6
to find FE:
FE=5x-2
FE=5(6)-2
FE=28

The height of an overhand volleyball serve can be modeled as h=-16t^2+20t+6. After how many seconds is the ball 11 feet.
Answers
Answer:
0.9043secs and 0.3456secs
Step-by-step explanation:
Given the height of an overhand volleyball modeled as h=-16t^2+20t+6.
If the height is 11feet, then;
11 = -16t^2+20t+6.
-16t^2+20t+6 - 11 = 0
-16t^2+20t-5 = 0
Multiply thriugh by -1
16t^2-20t+5 = 0
Factorize
t = 20±√20²-4(16)(5)/2(16)
t = 20 ±√400-320/32
t = 20 ±√80/32
t = 20 ±4√5/32
t = 20±8.94/32
t = 28.94/32 and 11.06/32
t = 0.9043 and 0.3456
Hence the required time are 0.9043secs and 0.3456secs
The volume of a cylinder is 65 cubic centimeters. Which equation can be used to find h, the height of the cylinder?
A. h = 65/b, where B is the base area of the cylinder.
B. h = 65 - B, where B is the base area of the cylinder.
C. h = 65B, where B is the base area of the cylinder.
D. h = B/65, where B is the base area of the cylinder.
Answers
Answer:
Im so sorry for do this but can you help me click my profile pic the click the last question PLZZZZZZZ will give 50 brain
Step-by-step explanation:
The equation that can be used to find h, the height of the cylinder, is h = B/65. The correct option is D.
How to calculate the height?The formula for the volume of a cylinder is:
V = Bh
Where V is the volume, B is the base area, and h is the height of the cylinder. We are given that the volume of the cylinder is 65 cubic centimeters, so we can write:
65 = Bh
To solve for h, we can divide both sides of the equation by B:
h = 65/B
Therefore, the equation that can be used to find h, the height of the cylinder, is:
D. h = B/65, where B is the base area of the cylinder.

1÷2(2x+6)=4x-1

Answers
Answer:
Step-by-step explanation:
1 ÷ 2(2x+6) = 4x-1
[tex]\frac{1}{2(2x + 6)} = 4x -1[/tex]
[tex]\frac{1}{2*2x+2*6 } = 4x - 1 \\\\\frac{1}{4x + 12} = 4x - 1\\[/tex]
1 = (4x - 1)(4x + 12)
Use FOIL method.
1 = 4x * 4x + 4x *12 - 1 * 4x - 1*12
1 = 16x² + 48x - 4x - 12
1 = 16x² + 44x -12
0 = 16x² + 44x - 12 -1
16x² + 44x - 13 = 0

Which expression models the phrase "Wally mowed two more lawns than he mowed last week"? n + 2 n minus 2 2 minus n 2 n
Answers
Given:
The phrase is "Wally mowed two more lawns than he mowed last week".
To find:
The expression that models the given phrase.
Solution:
Let the number of lawns mowed by Wally last week be n.
We know that, we use plus sign "+" for "more".
If Wally mowed two more lawns than he mowed last week, then the lawns mowed by the Wally this week is the sum of n and 2.
Lawns mowed this week = [tex]n+2[/tex]
The required expression for the phrase "Wally mowed two more lawns than he mowed last week" is n+2.
Therefore, the correct option is A.

C) 5x + 20 = 5x + 20
D) 9x = 9
Answers
Answer: I did the math in my head and I think it’s B
Step-by-step explanation:
2x - 6 = 2x + 8
Just looking at this, it doesn’t make sense. Two times a number - 6 cannot equal two times the same number +8.
But solving it mathematically, we want to get the variables on one side of the equation, so we subtract 2x from both sides:
2x - 2x -6 = 8
Then add 6 to both sides:
2x - 2x = 14
0 = 14 is untrue.
The other options’ answers:
B: x = 4.5
4x - 8 = 10
4x = 18
x = 4.5
C: has an infinite number of solutions. Anything you plug into x on one side of the equation you will plug in on the other side. Both sides are identical.
D: x = 1

Given the system of equation 7x-3y = 48 .......Eq 1 2x+ y = 35 ........Eq 2 __________ To solve this system by elimination and multiplication , i can ...............................
Answers
Answer:
x = 11.75
y = 11.5
Step-by-step explanation:
By Elimination Method:
7x - 3y = 48 ---- (1)
-
2x + y = 35 ----- (2)
Multiply equation (1) by 2 and equation (2) by 7
14x - 6y = 96
-
14x + 7y = 245
0 -13y = -149
-13y = -149
y = -149/-13
y = 11.5
From equation (2); replace y with 12
2x + y = 35
2x + 11.5 = 35
2x = 35 - 11.5
2x = 23.5
x = 11.75
