Answer:
easy peasy
Step-by-step explanation:
we have, area = 497 sq. units
that is, (pi) (radius)^2=497
=> (22/7) x r^2 = 497
=> r^2 = 158.13
=> r = √158.13
=> r = 12.57
now we also have radius, soooo
=> circumference = 2 (pi) (radius)
=> (2) (22/7) (12.57)
=> 79.01 inches
Answer:
Step-by-step explanation:
The coordinates of the given quadrilaterals are
The reflection in the line 
has the mapping,
We just have to swap the coordinates.
This implies that,
Therefore the correct answer is A.
Answer:
5/2
Step-by-step explanation:
1000m = 1km
1.75km = 1750m
1750 / 700 = 5/2
Answer:
see below
Step-by-step explanation:
Since RT bisects QRS
1/2 QRS = TRS
1/2 ( 9x+214) = -9x+53
Multiply each side by 2
9x +214 = -18x+ 106
Add 18x from each side
9x +214+18x = 106
27x +214 = 106
Subtract 214 from each side
27x = 106-214
27x =-108
Divide by 27
27x/27 = -108/27
x = -4
TRS = -9x+53
=-9 *-4 +53
= 36+ 53
=89
The formula for triangle area is b•h/ 1/2. so you would do 12•5=60. then divide that by 2 to get 30
