40.5 percent of a certain number is 65. what is the number?

2 answers:

6 0

The best way to do this is to set up a proportion

40.5 65
------- = -------
100 x

then cross multiply and divide

100 times 65=6500/40.5=160.5

the number is 160.5

I hope I've helped!

160.49 because you take 65 over x and 40.5 over 100 then cross multiply

Answer:

Step-by-step explanation:

18 = 2 * 3 * 3 = 2 *3²

$18*3^{(n+2)} = 2*3^{2}*3^{n+2}\\\\$

$= 2*3^{2+n+2}\\\\= 2*3^{n+4}\\\\= 2(3)^{n+4}$

Hint:

$a^{m}*a^{n} = a^{m+n}$

Point G is between F and H on line FH. Use the given information solve for x and then find FG AND GH.

Viktor [21]

Answer:

X=6

FG=31

GH=22

Step-by-step explanation:

Equation: FG+GH=FH

rewrite with values

4x+7 + 5x-8 = 53

combine like terms

9x-1 = 53

add 1 to both sides

9x = 54

divide by 9

x = 6

use 6 end solve for FG and GH

FG = 4(6) + 7 = 31

GH = 5(6) - 8 = 22

Check your answers.. Do FG and GH add up to equal FH (53)?

31 + 22 = 53

I hope this made sense.

REAL LIFE A cylindrical hazardous waste container has a diameter of 1.5 feet and a height of 1.6 feet. Abo

aivan3 [116]

Answer:

It can hold up to $1.256ft^3$ of waste

Step-by-step explanation:

Given

$D = 1.5ft$ -- Diameter

$h = 1.6ft$ -- height

Required

Determine the amount of waste it can hold

This simply means that we calculate the volume of the cylindrical container.

And this is calculated using:

$Volume = \pi r^2h$

Where

$\pi = 3.14$

and

$r = \frac{D}{2}$

$r = \frac{1.5}{2}$

$r = 0.75$

So, we have:

$Volume = 3.14 * 0.5^2 * 1.6$

$Volume = 1.256ft^3$

Hence, it can hold up to $1.256ft^3$ of waste
