Salid bought 35 feet of window trim at a hardware store. The trim cost $1.75 per foot, including sales tax. If salid paid with a $100.00 bill, how much change should he have received?

Answers

Answer 1

Answer: first we have to write down what we know and that is 35ft of window trim is what he has and for each foot of the 35 is a $1.75. so-->35(1.75)--> this is 61.25 or $61.25. He used 100.00 to pay so he did not use all of the 100. 100-61.25= is how much salid should recieve back which is $38.75.

Answer 2

Answer: If you would like to know how much change should Salid have received, you can calculate this using the following steps:

35 feet * $1.75 per foot = 35 * 1.75 = $61.25

$100.00 - $61.25 = $38.75

Result: Salid should have received $38.75.

Carol spent 3 hours on homework and Timothy spent 45 minutes on homework. What is the ration of the time Carol spent on homework to the time Timothy spent on homework * i got 8:1*a) 1:15
b) 1:4
c) 20:3
d) 4:1

Answers

it’s 4/1 because you want to get 3 hours converted into minutes, which is 180 minutes. Put 180/45 and simplify it, and the answer is 4/1

It’s d)4:1
First we have to convert hours into minutes so we have to multiply 3x60=180
Second we need to divide Carol’s spent over Timothy’s spent time. 180/45=4
This gives us the ratio of 4:1

Liam bought 5 7/8 pounds of steak. He used 2 1/16 pounds of the steak for a cookout. Liam has about how many pounds of steak remaining after the cookout?

Answers

Liam bought a total of 5 7/8 pounds of steak. Then he used 2 1/16 pounds of steak for a cookout.Given with the data above, let's find out how many pounds were left after he used some of it.=> Notice that the given numbers are fractions> => 5 7/8 pounds and 2 1/16 poundsSince these are mixed fraction, let's convert it to improper fraction. => 5 7/8 = (8 * 5 = 40 + 7 = 47) = 47 / 8=> 2 1/16 = (16 * 2 = 32 + 1) = 33 / 16The equation is now = 47/8 - 33/16=> Since they don't have the same denominator, let's find the lCD=> 47/8 - 33/16 = 94/16 - 33/16 = 61/16Let's change it to mixed fractions=> 61 /16 = 3.8 or => 3 . 8/100 = 3 2/25

C.

0.905

D.

0.403

Answers

Answer:

Probability (P) (k successes out of n trials) = nCk * p^k * (1-p)^(n-k), where nCk = n! / (k! * (n-k)!)

for this problem n=20, p = 1/6(probability of rolling 1 two) is approximately 0.1667

P ( of getting more that 3 two's) = 1 -P(0 two's out of 20 trials) -P(1 two out of 20 trials) -P(2 two's out of 20 trials) -P(3 two's out of 20 trials)

P ( of getting more that 3 two's) = 1 -0.026 -0.104 -0.198 -0.238 = 0.434
