Which equation can be used to find the volume of this solid?

Answers

Answer:

Option A, V = 3 * 5 * 4

Step-by-step explanation:

Volume of a Cube formula: V = w*h*l

Step 1: Plug in

V = whl

V = (5)(4)(3)

Answer: Option A, V = 3 * 5 * 4

V= 3 x 5 x 4
The equation for volume is length x width x height (which sides are length/width/height doesn't matter)

$\text{A polynomial must have multiple terms in its expression}\n\n\text{That means we could eliminate the last answer choice automatically}\n\n\text{There are different types of polynomials, in which you could see that}\n\text{there is a trinomial in one of the answer choices}\n\n\text{Your best answer choice would be the 2nd one:}\,\,6x^2+x+5\n\n\text{This is because there are different terms and there are multiple of them}$

Please help me with these two questions sorry the paper got Wet

8. For this problem, we simply need to take the volume of this cube. As we can remember, the formula for volume is simply length times width times height. In this figure, we have a length of 6, a width of 3, and a height of 4. So all we need to do to find the area is multiply.

6 * 3 = 18

18 * 4 = 72

The volume of our figure is 72 cubic inches.

9. We are trying to find the triangle that fits the description of obtuse and scalene. An obtuse triangle is one which has one angle with a measure of more than 90°. A scalene triangle is one in which no two sides are similar.

Triangle 9a fits this description, so you would mark yes on it.

Triangle 9b does NOT fit the description, since all angles have a measure of less than 90°, so we will mark a no on it.

Triangle 9c also does not fit the description, since it has an angle with a measure of exactly 90° (as indicated by the little square in the corner of the angle), so we will mark no on this one as well.

And there we have it.
Hope that helped! =)

A collection of 33 coins having dimes quarters and nickels, there are 3 times more nickels then dimes and half the amount of dimes as nickels, all of the coins equal $3.30 how many of each coin?

Answers

Answer:

Each coins are quarters of 6, nickels of 18 and the dimes of 9.

Step-by-step explanation:

There is a mistake in question.

The question must be:

A collection of 33 coins having dimes quarters and nickels, there are 3 times as many nickels as quarters, and one-half as many dimes as nickels, all of the coins equal $3.30 how many coins of each kind are there?

Now, to find the number coins of each.

Let the quarters be $x$ .

Nickels be $3x$ .

And the dimes be $(3x)/(2)$ .

So, the total collection of coins are:

$x+3x+(3x)/(2) =33.$

On adding the fractions we get:

$(2x+6x+3x)/(2) =33$

$(11x)/(2) =33$

Multiplying both sides by 2 we get:

$11x=66$

Dividing both sides by 11 we get:

$x=6.$

Thus, quarters = 6.

Nickels = $3x=3* 6=18.$

Dimes = $(3x)/(2) =(3* 6)/(2) =(18)/(2)=9 .$

Therefore, each coins are quarters of 6, nickels of 18 and the dimes of 9.

Mrs Larnell is making a snack packs for a a class picnic. She puts 1/4 pound of apples,1/8 pound of nut mix, and 1/16 pound of chocolate in each of the students packs. There are 24 students in the class.What is the total weight of the snack packs? Is there more than one way to solve this problem?

Answers

Answer=10 1/2 pounds

One pack has 1/4+1/8+1/16 pounds of snacks....

Lets starts off giving our fractions of 1/4, 1/8 and 1/16 a common denominator of 16.

1/4=4/16
1/8=2/16
1/16=1/16

So...

x=4/16+2/16+1/16
x=7/16

So... One pack has 7/16lbs of snacks in it

Multiply 7/16lbs by the total number of students(24)..

7/16*24=10 1/2 pounds
________________________________________________________
another way of solving this problem could be...

1/4*24=6
1/8*24=3
1/16*24=1.5

6+3+1.5=10.5 pounds
