Answer:
Step-by-step explanation:
if DF=20, then:
4x+8+2x-2=20
6x+6=20
6x=14
x=14/6
x=7/3
then
DE=4x+8
DE=4(7/3)+8
DE=(28/3)+24/3
DE=52/3
And
EF=2x-2
EF=2(7/3)-2
EF=14/3-6/3
EF=8/3
Answer:
22
Step-by-step explanation:
see below
It is the third option - 48.5%
Get the total of the even number then divide it by the total number of results.
For even, there are 67 twos, 59 fours, 71 sixes. The total is 406.
P(even) = [even] / [total]
P(even) = [67+59+71] / [67+59+71+64+73+72]
P(even) = 48.5%
The experimental probability of rolling an even number is 48.5%.
Answer:
m=3
Step-by-step explanation:
Perpendicular lines intersect at 90 degrees or perpendicular angles. As such, their slopes are related. The slope of each line is the negative reciprocal of the other. For the equation, 
. The slope or 
. This means the slope of the other line will be the negative reciprocal which is -(-3)=3
<span>500 = 10^n then use 1n and your n value will be about 2.7 and that will
give you 500 back use 10.
