Answer:
51
Step-by-step explanation:
area = pi x r^2
so
3.14 x 25
around 76
so
2/3 of 76
is
51
Answer:
1 hour
Step-by-step explanation:
Each graph shown lasts for 1/2 hour / 30 minutes
Answer:
76; 20
Step-by-step explanation:
s = small room = 2
l = large room = 4
14s + 12l = 28 + 48 = 76
as I said before s = 2 and l = 4
s*s + l*l = 2*2 + 4*4 = 4 + 16 = 20
Given:
Width of a rectangle = 
Length of the rectangle = 
To find:
The ratio of the width to the length.
Solution:
We need to find the ratio of the width to the length.

Putting the given values, we get





Therefore, the ratio of the width to the length is 1:3.
Answer:
Option 1
Similar triangles have proportional sides.
This means that the sides of ΔABC must have the same ratio to the sides of ΔSTR, ΔLKJ, or ΔDEF.
The base angle of ΔABC is 6 and therefore the base angle of the similar triangle should be divisible by 6. This leaves ΔSTR out
Continue the process with the other sides:
side BC is 4 units meaning the corresponding side of either ΔDEF or ΔLJK with have to be divisible by 4. in JKL the corresponding side KL is 9 units and not divisible by 4. Therefore, DEF is the correct answer since its corresponding sides are proportional
