Select the expression that represents the following statement: 52 minus 4 times the difference of 13 and 7.

vampirchik [111]

Answer:

(52 - 4) * (13 - 7)

Step-by-step explanation:

Step 1: Convert words into an expression

52 minus 4 times the difference of 13 and 7.

(52 - 4) * (13 - 7)

Answer: (52 - 4) * (13 - 7)

If needed simplify

(52 - 4) * (13 - 7)

48 * 6

Sam and Lou need a total of 1 foot of wire for a science project. Sam's wire measured 7/8- foot long. Do they have enough wire f

Reil [10]

Answer:

Yes, Sam and Lou have enough wire for science project.

Step-by-step explanation:

There is some data missing in the question, so complete question is below:

$Sam\ and\ Lou\ need\ a\ total\ of\ 1\ foot\ of\ wire\ for\ science\ project.$ $Sam's\ wire\ measured\ 8/12\ foot\ long.\ Lou's\ measured\ 7/8-\ foot \ \ long.$ $Do\ they\ have\ enough\ wire\ for\ the\ science\ project?$ $Explain \ your\ reasoning.$

Now, to get that whether they have enough wire for the science project or not.

Measurement of Sam's wire = $\frac{8}{12} \ foot.$

Measurement of Lou's wire = $\frac{7}{8}\ foot.$

Now, adding both the wires of Sam and Lou:

$\frac{8}{12} +\frac{7}{8} \\\\=\frac{16+21}{24} \\\\=\frac{37}{24}$

$=1\frac{13}{24} \ feet.$

As, Sam and Lou need a total of 1 foot of wire for the science project.

And, we see that the Sam's wire and Lou's wire combining gets $1\frac{13}{24}\ feet$ which is more than 1 foot.

Thus, wire they have is enough for science project.

Therefore, yes, Sam and Lou have enough wire for science project.

can I get help with this problem as well? I don't want to get it wrong then not be able to get the credit again. It's my last pr

Whitepunk [10]

Check the picture below.

well, the volume of the craft prism will simply be length * width * height, and we know that is 7140.

$\textit{volume of a rectangular prism}\\\\ V=Lwh ~~ \begin{cases} L=length\\ w=width\\ h=height\\[-0.5em] \hrulefill\\ L=17\\ h=28\\ V=7140 \end{cases}\implies \begin{array}{llll} 7140=(17)w(28)\implies \cfrac{7140}{(17)(28)}=w \\\\\\ 15=w \end{array}$

we know the area of the top is just w * 17, and the circle is just 2/5 of that, well that's just

$\cfrac{2}{5}(15)(17)\implies (2)(17)\cfrac{15}{5}\implies (2)(17)3\underset{\textit{area of the circle}}{\implies 102~in^2}$
