Answer:
5.4cm
Step-by-step explanation:
In similar triangles, the perimeter of the triangles will be in the ratio of their corresponding sides.
The ratio of their perimeter is
perimeterofΔ2 15
--------------------- = -------------
perimeterofΔ1 25
So, the side of triangle 2 will be
9 * 15 15
---------------- = --------------
sideofΔ2 25
=
⟹side of Δ2= 25 / 9∗15 =5.4.
Answer:
You will have 5-2=3 apples.
Answer: r = 1.69 inches
h = 2.15 inches
Step-by-step explanation: Volume of a solid is the amount of space contained within a solid.
Volume of a cone is directly proportional to radius and height:

They want the cones to hold the same volume of 9 cubic inches.
If height is 3:



r = 1.69 inches
When height is 3, radius is 1.69 inches for a cone to have 9 cubic inches of volume.
If radius is 2:


h = 2.15 inches
If radius is 2 inches, height of the cone is 2.15 inches.
Answer:
1. 4 as that is when he is closest.
2. 3 is when he is waiting as the graph is horizontal showing no movement
3. 4 would change as that is showing his pace walking home if it increased the slope would become steep but if it decreased it would level out more.
Step-by-step explanation:
It would be: -2/3 * -9/10 = 18/30 = 3/5
So, option B is your answer.
Hope this helps!
