Percent of change: $25;300% increase

2 answers:

8 0

First, find 300% of 25.

Percentages are parts of 100, so divide 300 by 100.

300 / 100 = 3.

So multiply that to 25.

3 * 25 = 75

Add it to 25:

75 + 25 = $100

100%+ 300%=400

So, 4.00*25=100.00

Your answer is 100

Hope this helps =)

5. Can someone explain how to solve this?

Answer:

AC = 5 cm

BD = 12.5 cm (3 sf) [or 2 × root 39]

BE = 6.93 cm (3 sf) [or 4 × root 3]

Step-by-step explanation:

CE = 8cm [CE is radius of circle]

AC + 3 = 8

AC = 5 cm

BC = 8cm [BC is a radius of circle]

(AC)^2 + (AB)^2 = (BC)^2 [Pythagoras theorem]

25 + (AB)^2 = 64

AB = 6.2450 cm (5 sf) [or root 39]

BD = 2(BA)

= 2(6.2450)

BD = 12.5 cm (3 sf) [or 2 × root 39]

(BA)^2 + (AE)^2 = (BE)^2 [Pythagoras theorem]

39 + 9 = (BE)^2

BE = 6.93 cm (3 sf) [or 4 × root 3]

The standard formula for the volume of a cone is V=πr2h3. If the cone is scaled proportionally by a factor of k, its volume beco

DaniilM [7]

The volume of a cone with base radius r and height h is

$V = \frac 1 3 \pi r^2 h$

What happens when we scale by k ?

Let V' be the volume of a cone with radius rk and height hk

$V' = \frac 1 3 \pi (rk)^2 (hk) = \frac 1 3 \pi r^2 k^2 h k = k^3 (\frac 1 3 \pi r^2 h) = k^3 V$

Find out the how many kilobytes have been downloaded so far .
To prove
As given
While waiting for a video game to download.
notice that 30 percent of 32000 kilobytes have been downloaded so far .
30% is written in the decimal form.

= 0.30
kilobytes uses in downloaded = 0.30 × 32000
= 9600 kilobytes
Therefore 9600 kilobytes have been downloaded so far .
