CF=EC=DC
2CF=CD
CD = 20 in.
On the basis of mathematical theory, the chance of occurrence of any event is called theoretical probability.
For example if we toss a coin then the probability of a head and a tail is half half i.e 0.5.
But the probability calculated by repeated experiments and examine the outcomes are called experimental probability.
For example if we toss a coin 20 times and got 9 times head and 11 times head then the probabilities are given by
These probabilities are different what we got in case of theoretical probabilities.
Total surface area of the present=
=2*(5 in * 4.5 in)+2*(5 in * 3.5 in) + 2*(4.5 in * 3.5 in)=
=45 in² + 35 in² + 31.5 in²=111.5 in²
answer:the total surface area of the present is 111.5 in²
Answer:
It will cost Emily $40 to rent the bike for 6 hours.
Step-by-step explanation:
SOLUTION:
Total cost equals = (cost per hour × number of hours) + initial bike cost.
Let, y be total cost and x = renting a bicycle for x hours.
y=5x+10
To calculate Emily's cost for 6 hours, let x=6.
y=5(6)+10
y=30+10
y=40
It will cost Emily $40 to rent the bike for 6 hours.
Answer:
c = 9
Step-by-step explanation:
2(3c+6)+7−5×1+2−1+9c=69+4c+5c
Add 12 and 7 to get 19.
6c+19−5×1+2−1+9c=69+4c+5c
Multiply 5 and 1 to get 5.
6c+19−5+2−1+9c=69+4c+5c
Subtract 5 from 19 to get 14.
6c+14+2−1+9c=69+4c+5c
Add 14 and 2 to get 16.
6c+16−1+9c=69+4c+5c
Subtract 1 from 16 to get 15.
6c+15+9c=69+4c+5c
Combine 6c and 9c to get 15c.
15c+15=69+4c+5c
Combine 4c and 5c to get 9c.
15c+15=69+9c
Subtract 9c from both sides.
15c+15−9c=69
Combine 15c and −9c to get 6c.
6c+15=69
Subtract 15 from both sides.
6c=69−15
Subtract 15 from 69 to get 54.
6c=54
Divide both sides by 6.
c = 54/6
Divide :)
c = 9
