Answer:
7.74596669241 (maybe)
Step-by-step explanation:
I havent really done this in a while but I started by making the line into a right triangle and counted how many boxes were inside(6 on the bottom 4 on the side). Then I used the Pythagorean theorem (which is the process of taking the sides and making them squares) < To simplify that explanation (I squared the sides(6 and 4).) so now we are left with 6² + 4² = x². next what you do is simplify your terms. (6² = 36, 4² = 24. 36 + 24 = 60) We have 60 = x² but we aren't don't yet, now we have to remove the square from x. and to do that we have to square root 60 and x² ( squared numbers being square rooted just leaves the regular number.) when square rooting 60 you are left with 7.8≈.
I hope this helps you, like i said its been a while since ive done this.
Answer:
1. a. 544%
b. 84%
2. 175
3. $867.18
Step-by-step explanation:
1. a.2.32-0.36=1.96
1.96/0.36=5.44
5.44*100=544
b. 1.96/2.32=0.84
0.84*100=84
2. let x = # of 7th graders
let y = # of 8th graders
y is 125% of x
y=1.25x
x=140
y=1.25*140
y=175
3. A=P(1+r)^t
A=700(1+0.055)^4
A=867.18
No, 14 and -7 are different numbers
Answer:
-6x^4-14x^2+12x+2
Step-by-step explanation:
The height will be 4 cm.
Explanation
<u />The volume of a cylinder is given by the formula V=πr²h. For a volume of 36π cm³ and a radius of 3 cm,
36π = π(3²)h
36π = 9πh
Divide both sides by 9π:
36π/9π = 9πh/9π
4 = h
