The new price would be $105. To solve this, you need to figure out what 40% of 75 is. A simple way to do this is to figure out what 1%, or in this case 10%, of 75 is! Take 75 and divide it by 100, and you get .75. Doing this tells you what 1% of 75 is. Now, multiply .75 by 40, and you get 30! Now add 30 and 75, and you get 105. I hope this helped! Could I possible get brainliest?

A zookeeper is monitoring the population of gazelles. The herd needs three times more males than females to thrive, and the zoo

avanturin [10]

Answer:

0 < x ≤ 12 and 0 < y ≤ 36

Step-by-step explanation:

Here, x represents the number of female gazelles and y represents the number of male gazelles.

The zoo only has room for 12 female gazelles.

∵ The number of rooms must be more than or equal to the total female gazelles ,

12 ≥ x

Also, number of animals can not be negative,

And, it must be greater than 0.

⇒ 0 < x ≤ 12,

⇒ 3(0) < 3x ≤ 3(12)

⇒ 0 < 3x ≤ 36

∵ Number of males gazelles = 3 × number of female gazelles

⇒ y = 3x

⇒ 0 < y ≤ 36

Hence, the constraints to represent a thriving population of gazelles at the zoo are,

0 < x ≤ 12,

0 < y ≤ 36

It takes 3 hours to cook an 8-pound turkey. How long would it take to cook a turkey that is 14 pounds? Round to the nearest tent

pochemuha

Answer:

5.3 hours

Step-by-step explanation:

Given:

3 hours = 8lbs. turkey

?? hours = 14lbs. turkey

Do proportions:

$\frac{3}{8}$ = $\frac{x}{14}$ <-- Cross Multiply

42 = 8x <-- Solve for x

x = 5.25

Round to the nearest tenth:

x = 5.3 hours

In the park, Bryce hikes 4 1/2 mi and Jessie hikes 6 7/16 mi. How much farther does Jessie hike than Bryce? Express your answer

soldier1979 [14.2K]

is simply the difference of both amounts, but firstly let's convert the mixed fractions to improper, and subtract.

$\bf \stackrel{mixed}{4\frac{1}{2}}\implies \cfrac{4\cdot 2+1}{2}\implies \stackrel{improper}{\cfrac{9}{2}}
\\\\\\
\stackrel{mixed}{6\frac{7}{16}}\implies \cfrac{6\cdot 16+7}{16}\implies \stackrel{improper}{\cfrac{103}{16}}
\\\\[-0.35em]
\rule{34em}{0.25pt}\\\\
\stackrel{Jessie}{\cfrac{103}{16}}-\stackrel{Bryce}{\cfrac{9}{2}}\implies \stackrel{\textit{our LCD is 16}}{\cfrac{(1)103-(8)9}{16}}\implies \cfrac{103-72}{16}\implies \cfrac{31}{16}\implies 1\frac{15}{16}$
