Answer:
$50.23
Step-by-step explanation:
f(t)=1.35(t)+9.73
First I found out how many years are after 1985 so you would do 2020-1985 which equals 30.
I plug it in for t.
f(t)=1.35(30)+9.73
Then you multiply 1.35 and 30 which would leave us with.
f(t)=40.5+9.73
Add them and you get $50.23
Answer:
B) 200 miles.
Step-by-step explanation:
Let M = miles that you need to drive
45 + 0.295M = 90 + 0.07M
90 - 45 = 0.295M - 0.07M
45 = 0.225M
M = 45/0.225
M = 200

Answer:
X=50 hope this helps:)
Step-by-step explanation:
90+110=200
360-200=160
160=3x+10
150=3x
X=50
4x - 2y = 10
-2y = -4x + 10
y = 4/2x - 10/2
y = 2x - 5 <==
Answer:
Step-by-step explanation:
there are 40320 possible arrangements. that would be 8!
the probability of picking the correct order randomly would be 1 / 40320 = .0000248015873.
in order words, the probability of picking the correct order on a random basis, such as picking the names out of a hat, is not very good.
<u>for example:
</u>
suppose there were only 3 reamining candidate.
3! = 3*2 = 6
there would be 6 possible arrangements. if the candidates were abc, then the 6 possible arrangements would be:
abc
abc
bac
bca
cab
cba
for 4 candidates, multiply 6 * 4 = 24
then 5 * 24 = 120
then 6*120 = 720
then 7*720 = 5040
then 8 * 5040 = 40320
1 / 6 is manageable.
1 / 24 less.
1 / 8 becomes pretty impossible.
