So I think that number 6 is just dividing by 3 and the second one doesn't like divide so number 7 is no and number 6 is yes

I'm basically seeing if I take one of the numbers out then cross multiply, and see if I get the same number I took out or not.
6. I'm taking the 2 out for this one.
6*8=48
48/ 24=2
it should be proportional.

7.I'm taking out the 2
5*8= 40
40/25= 1.6
this one should not be proportional

The volume of the single crayon is 89.5 cm³, then the total volume of the crayons will be 2148 cm³. Then the correct option is D.

<h3>What is Geometry?</h3>

It deals with the size of geometry, region, and density of the different forms both 2D and 3D.

A Crayon is shown here.

There are 24 crayons in a box.

The approximate total volume of the crayons will be

Total Volume of crayons = 24 × volume of the single crayon

The crayon is the combination of the cone and the cylinder

Then the volume of the single crayon (V₁) will be

$\rm V_1 = \left ( \dfrac{1}{3} \times \pi \times r^2 \times h \right ) + \left ( \pi \times r^2 \times h \right )\\\\\rm V_1 = \left ( \dfrac{1}{3} \times \pi \times 1.5^2 \times 2 \right ) + \left ( \pi \times 1.5^2 \times 12 \right )\\\\V_1 = 4.712 + 84.82\\\\V_1 = 89.535 \approx 89.5$

Then the Total volume will be

Total volume = 24 × 89.5

Total volume = 2148 cm³

Plz help!!

Answer:

150 ft^3

.1 ton or 200 lbs

Step-by-step explanation:

The volume is given by

V = l*w*h

V = 5*5*6

V = 150 ft^3

To find how much 1 ft^3 weighed take the weight and divide by the volume

15 tons / 150 ft^3

.1 ton / 1 ft^3

1 ft^3 weights .1 ton

We know that 1 ton = 2000 pounds

.1 ton = 200 pounds

On a particular night, a baseball stadium sells 60% of its seats, and of those, 15% do not end up showing up to the game.Assumin

Lelechka [254]

Answer:

Step-by-step explanation:

so llets find what 15% of 60% really is,

0.15*0.60=0.09

0.09 AKA 9%

so since 9% of people didn't show up we can subtract 9% from 60%

so 60-9=51

51% of setas are taken

to find the percent of seats still empty, subtract 100 form 51

100-51=49

49% of seats are still empty

Hope this helsp!
