Answer: a. 14% decrease or 86% of the whole

B. 137.5% increase

Step-by-step explanation:

A. Divide new price by old price and you get .86, change that to a percent by multiplying by 100. That equals 86%, the percent of change would be the difference of 100% to 86%, which is 14%

B. Use above explanation but don’t find the difference. 77/56= 1.375, 1.375*100=137.5

What would be the volume of the cone that has the same measurement as the cylinder above in the pic

fomenos

$▪▪▪▪▪▪▪▪▪▪▪▪▪ {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪$

Volume of cone will be ~

$\fbox \colorbox{black}{ \colorbox{white}{volume} \: \: \: \: \: \colorbox{white}{=} \: \: \: + \colorbox{white}{462 \: cm³ }}$

$\large \boxed{ \mathfrak{Step\:\: By\:\:Step\:\:Explanation}}$

Let's find the volume of cone with ~

radius (r) = 7 cm

height (h) = 9 cm

And as we know, volume of cone is equal to ~

$\dfrac{1}{3}\pi {r}^{2} h$

now, let's plug in the values and find the volume ~

$\dfrac{1}{ \cancel{3} }\times \dfrac{22}{\cancel{7}} \times \cancel{7 }\times 7 \times \cancel{9}$

$1 \times 22 \times 7 \times 3$

$462 \: \: {cm}^{3}$

Volume of cone is 462 cm³ = 462 ml

Answer:

44, parallel, equals half

Step-by-step explanation:

i am not sure is this is correct but, I think that x+5 that x is 27 and the other one is 12 and the 27+5 is 32 and 32+12 is 44 so i am guessing that the BD side is 44, i guess and about the other , the first black space is parallel and the second is equals half

-3(2x+4) = 3(x-6)<br> i need steps too

Bezzdna [24]

If you are looking to find the value of x then you have to use distributive property.

1st: multiply -3 by 2x and 4 -3(2x+4)

-6x -12

2nd: do the same thing on the other side which is multiply 3 by x and -6

3(x-6)

3x-18

3rd: Then you have -6x-12=3x-18

+12 +12

add 12 to each side so then you have -6x=3x-6

then divide by -6 on each side and the answer is x= 2/3
