myrzilka [38]
Getting the percentage increase, we can form the formula or equation.
Percentage increase = ($1.00 - $0.40) / $0.40 * 100
<span>Percentage increase = ($0.60) / $0.40 * 100
</span><span>Percentage increase = 1.5 * 100
</span><span>Percentage increase = 150%
</span>

in one week katy walks 1,720 meters and runs 1,925 meters. she performs the same workouts for three weeks. how many meters does
Klio2033 [76]

Answer:

10,935 meters.

Step-by-step explanation:

Find how many meters she walks in 1 week, so you add the 1,720 and the 1,925 and you would get 3,645. If she does the same thing for 3 weeks, you multiply the 3,645 by 3, so you get 10,935 meters

What is the missing numerator in 2 7/9 = 1 _/9 ?
liberstina [14]
First off, we'll convert the mixed fractions to "improper", and proceed,

\bf \stackrel{mixed}{2\frac{7}{9}}\implies \cfrac{2\cdot 9+7}{9}\implies \stackrel{improper}{\cfrac{25}{9}}&#10;\\\\\\&#10;\stackrel{mixed}{1\frac{x}{9}}\implies \cfrac{1\cdot 9+x}{9}\implies \stackrel{improper}{\cfrac{9+x}{9}}\\\\&#10;-------------------------------\\\\&#10;\cfrac{25}{9}=\cfrac{9+x}{9}\implies 25=9+x\implies 25-9=x\implies 16=x
