Answer:
1/4
Step-by-step explanation:
8 divided by 2= 0.25=1/4
#1 is "given"; #2 is angle 3 is congruent to angle 4; #3 is angle 1 is congruent to angle 2; #4 is RF is conguent to RF; #5 is ASA congruency; #6 is CPCTC
Answer:
length=8 , wide=5
Step-by-step explanation:
Let length=x and wide=y
convert the question into two equations
3+y=x .......1
xy=40 .......2
so we need to substitute x into y or y into x
x=3+y ,
(3+y)y=40
y²+3y=40
y²+3y-40=0
from that use calculator or manually factorise it
(y+8)(y-5)=0
y= –8 , y=5
we need to choose positive answer so y=5
then find for x
5x=40
x=8
Answer:
A
Step-by-step explanation:
square: 10² = 100
Circle: π*5² = 3.14*25 = 78.5
In the squqre not in the circle: 100-78.5 = 21.5
