Sue drank 2/5 of her water bottle and sally drank 4/10 of her water bottle how much water did both girls drank?

stealth61 [152]

well, clearly the LCD from the denominators of 5 and 10 is just 10, thus

$\bf \stackrel{\textit{Sue}}{\cfrac{2}{5}}+\stackrel{\textit{Sally}}{\cfrac{4}{10}}\implies \stackrel{\textit{LCD of 10}}{\cfrac{(2)2~~+~~(1)4}{10}}\implies \cfrac{2+4}{10}\implies \cfrac{6}{10}\implies \stackrel{\textit{simplified}}{\cfrac{3}{5}}$

A car is driving away from a crosswalk. The formula d = t2 + 2t expresses the car's distance from the crosswalk in feet, d, in t

alukav5142 [94]

Answer:

8 feet per second.

Step-by-step explanation:

We have been given that a car is driving away from a crosswalk. The formula $d=t^2+2t$ expresses the car's distance from the crosswalk in feet, d, in terms of the number of seconds, t, since the car started moving.

We will use average change formula to solve our given problem.

$\text{Average change}=\frac{f(b)-f(a)}{b-a}$

$\text{Average change}=\frac{d(5)-d(1)}{5-1}$

$\text{Average change}=\frac{(5)^2+2(5)-((1)^2+2(1))}{4}$

$\text{Average change}=\frac{25+10-(1+2)}{4}$

$\text{Average change}=\frac{35-3}{4}\\\\\text{Average change}=\frac{32}{4}\\\\\text{Average change}=8$

Therefore, the the car's average speed over the given interval of time would be 8 feet per second.
