Jasmine found a wooden jewelry box shaped like a right rectangular prism. What is the volume of the jewelry box?
Rus_ich [418]

Answer:

The volume of the jewelry box will be given by,

\text{Volume}=\text{l}\times \text{w}\times\text{h}

Step-by-step explanation:

It is provided that, Jasmine found a wooden jewelry box shaped like a right rectangular prism.

Consider the diagram below for the shape of a right rectangular prism.

The volume of a right rectangular prism is given by the formula:

\text{Volume}=\text{l}\times \text{w}\times\text{h}

Here,

l = length of the rectangle

w = width of the rectangle

h = height of the rectangular prism

Thus, the volume of the jewelry box will be given by,

\text{Volume}=\text{l}\times \text{w}\times\text{h}

A sporting goods store sells right-handed and left-handed baseball gloves. In one month, 12 gloves were sold for a total revenue
stepladder [879]

Answer:

9 right-handed gloves and 3 left-handed gloves were sold.

Step-by-step explanation:

Given:  In one month, 12 gloves were sold for a total revenue of \$561.

            right-handed gloves cost \$45 and left-handed gloves cost \$52.

To find: How much of each type of gloves did they sell?

Solution: Let they sell x  right-handed gloves, and y left-handed gloves.

Now, cost of each right-handed gloves =\$45

cost of each left-handed gloves =\$52

Total revenue =\$561

So, we get

45x+52y=561\:\:\:...(i)

Also,  in a month 12 gloves were sold.

So, we get

x+y=12\:\:\:...(ii)

Now, from (ii) we get, x=12-y.

Putting x=12-y in equation (i), we get

45(12-y)+52y=561

\implies 540-45y+52y=561

\implies7y=561-540

\implies7y=21

\implies y=\frac{21}{7}

\implies y=3

Now, putting y=3 in equation (ii), we get

x+3=12

\implies x=12-3

\implies x=9

Hence, 9 right-handed gloves and 3 left-handed gloves were sold.

Kim purchased 6 small containers of potato salad and Seth purchased 2 extra large containers of potato salad. What is the differ
icang [17]

I am assuming that the attached is the complete question and we need to get the information from the table.

From the table we know the below fact:

1 \; small \; container \; of \; potato \; salad \; Weighs \; \frac{2}{8} \; pounds\\\\1 \; extra \; large \; container \; of \; potato \; salad \; Weighs \; \frac{9}{8}  \; pounds

Weight \; of \; 6 \; small \; container = 6 \times \frac{2}{8}  = \frac{12}{8}  \; pounds\\\\Weight \; of \; 2 \; Extra \; large \; container = 2 \times \frac{9}{8} \; = \; \frac{18}{8}  \; pounds

Conclusion:

The difference in weights, in pounds of Kim’s and Seth’s purchases is given below:

\frac{18}{8} - \frac{12}{8} =  \frac{18-12}{8}   = \frac{6}{8}  \\\\Simplifying \; the \; fraction \; dividing \; by \; 2 \; on \; both \; numerator \; and \; denominator\\\\ \frac{6 \div 2}{8 \div 2}  = \frac{3}{4}

Final answer : <em><u>0.75 pounds</u></em>
