Need help, What is the volume? and can you explain how you got the answer :)

Answers

Answer/Explanation:

To find out the volume of this Rectangular Prism you have to multiply by length * width * height.

So what's [tex]3\frac{3}{8} *2?[/tex] It's [tex]\frac{27}{4}[/tex], and since there are [tex]2[/tex] sides of the same length * width * height, so [tex]\frac{27}{4} *2=\frac{27}{2}[/tex].

So now the upper and bottom face of the Rectangular Prism are figured out.

Now we have to do [tex]2*2[/tex], so what's [tex]2*2?[/tex] It's [tex]4[/tex]. Now like before there are [tex]2[/tex] sides of the same length * width * height, so we do [tex]4*2[/tex], and what's [tex]4*2?[/tex] It's [tex]8[/tex], now we add them together which is [tex]\frac{27}{2} +8=\frac{43}{2}[/tex], or we can say the answer is [tex]21.5[/tex] in decimal form.

So the Volume = [tex]21.5[/tex] or [tex]\frac{43}{2}[/tex]

Wait it's actually [tex]\frac{27}{4} *4[/tex] which is [tex]27[/tex], so then we actually do [tex]27+8[/tex], which is [tex]35[/tex].

SO IT'S ACTUALLY 35
The answer is 35. Hope this helps:)

83º + 29º + z = 180º

112º + z = 180º

z = 180º - 112º

z = 68º

A car has 15 gallons of gas in its tank. The car travels 35 miles per gallon of gas. It uses 135 of a gallon of gas to go 1 mile. How much gas does it use to go 100 miles?

Answers

2.86 gallons

For the 6th annual school fundraiser, Daisy needs to sell 38 rolls of
wrapping paper. So far, she has sold 2.24 rolls to her grandmother, 5.75
rolls to her uncle, and .6 rolls to a neighbor. How many more rolls of
wrapping paper does Daisy need to sell? If each roll costs $3.46, how
much money can Daisy make?

Answers

Answer:

She needs to sell the rest of her 29.41 rolls of wrapping paper. If she sells all of her rolls of wrapping paper, she'll be able to get a total of $131.48.

Step-by-step explanation:

To get the answer to "How many more rolls of wrapping paper does Daisy need to sell?" you would have to add up how many she already sold which is

2.24 + 5.75 + 0.6 = 8.59

and then subtract 8.59 from the total of rolls she's supposed to sell.

38 - 8.59 = 29.41

To get $131.48

You multiply how much each roll costs to the total of rolls she's supposed to sell:

38 * 3.46 = 131.48

Jayden used a Groupon at the local pizza shop. Instead of paying $15, for the pizza, he paid $12.
Haley and Arianna agree that the percent of decrease is 20% but their explanations differ. Haley says to find the 20%, you have to determine what percent of 15 is 12. Arianna thinks you have to determine what percent of 15 is 3. Who is correct?

Answers

Answer:

Arianna is correct

Step-by-step explanation:

She is correct because they need to find how much is the discounted price, which is 3. So to see what percentage it is, they need to see how much 3 is worth in comparison to 15. If we spilt 15 into 5 parts to make every part worth 20%, the answer would be 3. Thus Arianna is correct.

arianna is the correct answer
