The prism has a volume of 60 in3. What would the volume of the prism be if each dimension were tripled?(The shape is a rectangular prism, if that helps)

Answers

First, let's make a possible dimension of the prism. 
We have to divide 60 by a number so when you multiply those three numbers it equals 60. We can try multiplying 5 by 4 by 3 and it gets us 60. This is one possibility. 
So now we triple the sides. 
Triple is to make three times as much (multiply by three)
5*3=15
3*3=9
4*3=12
Now lets find the volume
Volume= l*w*h
Volume= 15*9*12=1,620
I think this would work for any dimension you choose.
The volume of the prism will be 1,620 in3 if the dimensions were tripled.

The smaller barn is similar to the larger barn by a scale factor of 60%. What are the height and width of the smaller barn?

The height is 1.2 and the width is 1.2 in.

The height is 1.4 in. and the width is 1.4.

The height is 0.12 in.and the width is 0.12 in.

The height is 2in and the width is 1.2 in.

Answers

Answer:

The correct option is 1.

Step-by-step explanation:

The height and width of larger barn is 2 in. and 2 in respectively.

It is given that the smaller barn is similar to the larger barn by a scale factor of 60%. It means the height and width of the smaller barn is 60% of the height and width of the larger barn.

The height of smaller barn is

2* (60)/(100)=(120)/(100)=1.2

The width of smaller barn is

2* (60)/(100)=(120)/(100)=1.2

Therefore the height and width of smaller barn is 1.2 in. and 1.2 in respectively. Option 1 is correct.

Answer:

The correct answer is 1.2 in by 1.2 in

Hallie is trying to win the grand prize on a game show. Should she try her luck by spinning a wheel with 6 equal sections labeled from 1 to 6 and hope she gets a 5, or should she roll two number cubes and hope she gets the same number on both cubes. Show your work?

Answers

A. likely

B. unlikely

C. There is a greater chance in picking to purple marbles because there are less of the white and more purple.

Hallie should spin the wheel because u have a greater chance of landing on a 5 then rolling two number cubes and hoping both number cubes come to equal 5.

two white marbles: probability first is white is \frac{2}{9} probability second is white given that the first is white is \frac{1}{8} again probability both happen is \frac{2}{9}\times \frac{1}{8}

Hope this helps.

What is 216÷18 using base ten blocks

Answers


the blocks for this one is 216 tenths and 18 ones


Final answer:

To solve 216 ÷ 18 using base ten blocks, we need to divide the base ten blocks into 18 groups and determine the result.

Explanation:

To solve 216 ÷ 18 using base ten blocks, we can start by representing the dividend, 216, using base ten blocks. We can use 2 hundred blocks, 1 ten block, and 6 one blocks. Next, we need to divide these blocks into 18 groups.

We start by grouping the hundred blocks. We can fit 1 hundred block into 18 groups, which leaves us with 1 hundred block remaining. We then move to the ten block, which we can fit 17 groups into, leaving us with 1 ten block remaining. Finally, we divide the 6 one blocks into 18 groups, but since 18 is greater than 6, we cannot form any complete groups with the remaining ones. Therefore, the quotient is 1 hundred, 1 ten, and 0 ones, which we can rewrite as 110.
