Jing spent 1/3 of her money on a pack of pens, 1/2 of her money on a pack of markers, and 1/8 of her money on a pack of pencils.

Reika [66]

As per the problem

Jing spent $\frac{1}{3}$ of her money on a pack of pens.

$\frac{1}{2}$ of her money on a pack of markers.

and $\frac{1}{8}$ of her money on a pack of pencils.

Total fraction of money spent cab be given as below

Fraction of Money Spent = $\frac{1}{3} +\frac{1}{2}+\frac{1}{8}$

Take the LCD of denominator, we get LCD of (3,2,8)=24

Fraction of Money Spent = $\frac{8+12+3}{24} =\frac{23}{24} \\\\$

$\\ \text{Hence fraction of Money Spent }=\frac{23}{24} \\ \\ \text{Fraction of Money left}=1-\frac{23}{24} \\ \\ \text{Simplify, we get}\\ \\ \text{Fraction of Money left}=\frac{24-23}{24} \\ \\ \text{Fraction of Money left}=\frac{1}{24}$

kelli and her faimly went to the beach for a vacation. they drove 293 miles 7 hours to get theredid they drive each hour

Inessa [10]

Ok so, Since Kelli and her family drove a total of 293 miles in 7 hours, then your equation should be $\frac{293miles}{7hrs}$
Now, since you have your ratio you divide 293 by 7 in order to get how many miles were driven in one hour
$\frac{293}{7}$ = 41.85714286 miles/hr

A 3-pound tub of butter at n dollars per pound costs $3.85. 3n = 3.85 3 - n = 3.85 3 + n = 3.85 3/n = 3.85

Elis [28]

Given:
3-pound tub of butter costs $3.85

3.85/3 = 1.2833 per pound.

3n = 3.85

3(1.2833) = 3.85
3.8499 = 3.85
3.85 = 3.85

The perimeter of a rectangle is 72 m. The width of the rectangle is 16 m. What is the area of the rectangle?

liq [111]

Answer:

320m

Step-by-step explanation

a rectangle has four sides, two pairs of identical sides. So two sides are 16. So that adds up to 32. Perimeter is all sides added together. so it has to add up to 72. 72 minus 32 is 40, so two of the sides have to be 40. Area is length times width, so 16 times 20, which is 320.
