Answer:

-3

Step-by-step explanation:

3-(7-2x) > -8

get rid of the parentheses because there is a minus sign before them

3-7+2x > -8

replace x with all the numbers (one by one not all at once) and see if the equation is correct until you find the number that makes it incorrect.

<u>EXAMPLE:</u>

3-7+2(1) > -8 parentheses next to a number means multiply

3-7+2 > -8

3-7 = -4

-4 + 2 = -2

-2 is greater than -8

The rate of U.S. per capita sales of bottled water for the period 2007–2014 could be approximated by s(t) = 0.25t2 ? t + 29 gall

julsineya [31]

Answer:

117 gallons

Step-by-step explanation:

The expression that describes the rate of U.S. per capita sales of bottled water for the period 2007–2014 is:

$s(t) = 0.25t^2-t+29$

Since t=0 at 2007. At 2009 and 2013, t is:

$t_1=2009-2007 = 2\\t_2=2013-2007 = 6$

The definite integral of the expression from t=2 to t=6 is:

$s(t) = 0.25t^2-t+29\\\int\limits^6_2 {s(t)} \, dt= \int\limits^6_2 {(0.25t^2-t+29)} \, dt\\\int\limits^6_2 {s(t)} \,dt= (\frac{t^3}{12} -\frac{t^2}{2}+29t +c)|^6_2 \\S(6) -S(2) = (\frac{6^3}{12} -\frac{6^2}{2}+29*6 +c) - (\frac{2^3}{12} -\frac{2^2}{2}+29*2 +c)\\S(6) -S(2) = 117.333\ gallons$

Rounded to the nearest gallon, the estimated total U.S. per capita sales of bottled water from the start of 2009 to the start of 2013 is 117 gallons.

Help please!! percentages thank you!!

Zanzabum

Answer:

16=25%

x=100%

25x=1600

x=64

6300/1260 * 100 = 20

100 - 20 = 80%

Total: 40

Set desingers: 16

16/40 = 40%

500*22%=110

500-110=390

Hope this helped you! I would appreciate a Brainliest, if this answer helped you out!
