Answer:
15 figures
Step-by-step explanation:
To know with this, and knowing that each dimension is 10% longer, let's do a simple example assuming some random values.
Let's suppose that you have cylinder with a radius of 3 cm and height of 5 cm. The volume of this cylinder is:
V = π*(3)^2*5 = 45π cm^3
Now, if we raise the dimensions by 10%, the radius and height will be 3.3 and 5.5 respectively so, the new volume (V2) will be:
V2 = π*(3.3)^2*5.5 = 59.9π cm^3
So the ratio of both volumes is:
59.9π/45π = 1.331
This means that each new solid would have 1.331 times the volume of the original solid. Therefore, we can stablish a relation between the original figures and the new ones calling "x" the number of new figures so:
20 = 1.331x
solving for x:
x = 20/1.331
x = 15.03
You can round this to 15.
No because if a number is a whole number then it is also a rational number and an integer
Answer:
Step-by-step explanation:
When I divided 4/7, I got .5714285714 then I divided 13/20, and I got .65 so I would say 4/7 I believe.
When I divided 1/4, I got .25 then I divided 1/6, and I got .1666666667 so I would say 1/4 I believe.
When I divided 5/6, I got .8333333333 then I divided 2/3, and I got .6666666667 so I would say 5/6 I believe.
I definitely hope this helps you, I tried my best! XO
Lets use a rule of three simple with direct proportion to solve:
20 boxes -----> 15 min
100 boxes ----> x
x = (100)(15)/20
x = 75
therefore it takes 75 mins to stack 100 boxes
If we use fractions to solve:
15/20 = x/100
and solve for x.
20/15 = 100/y
solve for y
