8 3/ 5 so that is the answer
Answer:
1. 7 hours
2. No, he will not.
3. 70 Miles/ hour
Step-by-step explanation:
1. She went 225 miles in 3 hours so divide 225 by 3, you get 75 miles per hour. She needs 300 more miles to complete the trip so multiply 75 miles x 7 hours - 7 hours because she already traveled 3 hours and it takes 4 more hours - and you get 525 Miles, which means she reached her destination.
2. 200 miles divided by 4 hours means he travels at 50M/h. He needs 263M more to complete the journey, and only has 5 hours left. Multiply 50miles x 5 hours, and you will see that it adds up to 450 Miles in 5 hours. He is 13 miles short. Therefore he will not get there in time.
3. Divide 240M by 6 hours. They travel 40M/ h. They need a total of 520 miles, which is now 280 since they already travelled 240M. If you divide 280 miles by 40M/ h, you get 7 hours, but you need 4 hours. Keep bumping it up until you reach 280 miles/ 70 miles per hour. Which will give you 4 hours. Therefore they need to travel at 70m/h to reach their destination within 4 hours.
Answer:
0.7455
Step-by-step explanation:
First, we note that there are C
= 220 ways of selecting the defective items.
The probability that the inspector will have to test at least 9 widgets would be 1 minus the probability that the inspector will have to test 8 or less widgets.
This is 1 - P(8 or less widgets have to be checked)
1 - 
= 1 - 56/220
= 1 - 0.2545
= 0.7455
Answer:
1) The original price is 8920 2) The mark up is 580
Step-by-step explanation:
!)We need to find out the initial price, suppose it is equal to 100 percents. The price was raised and it has reached 100+6.5= 106.5 percents . 106.5 percents from initial price is the new price (RM 9500). Find out the value of one percent
9500:106.5= 89.2 (approximately).
2)Then find the original price multiplying the value of percent by 100. 89.2*100= 8920 - initial price
3)Then mark up is a remainder between old price and new price . It is 9500-8920= 580.
Answer:
Option B.
Step-by-step explanation:
We can see that we have an asymptote at x = 2
Remember that in a rational function, the asymptote is at the x-value such that the denominator is equal to zero.
So, the denominator is something like:
(x + a)
we have that the denominator is zero when x = 2
Then:
(2 + a) = 0
solving that for a, we get:
a = -2
Then the denominator of the rational function is:
(x - 2)
For the given options, the only one with this denominator is option B, then the correct option is B.
