4÷1/3 Therefore it would be 4×3/1 this is because u reciprocate which basically means switching the denominator and numerator We do this because when we change the symbols in order to find the answer the denominator and numerator swap or switch places. 4×3/1 =12

It would be 5 over 1 then you change it to multiplying and make the 1/5 a 5/1 to get 25/1

a falling object travels a distance given by the formula d=5t + 16t^2 ft, where t is measured in seconds. how long will it take

Butoxors [25]

Its given that

$d=5t+16t^{2}$

We need to find t when d = 74

Therefore, $74=5t+16t^{2}$ or

$16t^{2}+5t-74 = 0$

$16t^{2}+37t-32t-74 = 0$

t(16t + 37) - 2(16t + 37) = 0

(t - 2)(16t + 37) = 0

t - 2 = 0 or 16t + 37 = 0

t couldn't be negative.

Therefore, t = 2

Hence, it will take 2 seconds for the object to travel 74 feet.

Can anyone actually help and not just bs me, plsss and thank you!

Using conversions between odds and probabilities, we have that:

1. A) 4:21

2. 0.952 probability that a bag of flour passes inspection.

3. C) 1:39

4. 41:59.

5. 14:11

A probability is the number of desired outcomes divided by the number of total outcomes.

An odd is given by a:b, in which a is the number of successes and b is the number of failures.

Item 1:

Probability of 0.16, thus, for 100 trials, 16 successes and 84 failures, and the odd is:

16:84, which, simplifying by 4, is 4:21.

Item 2:

Odd of 20:1 means that 20 + 1 = 21 trials, there are 20 successes, thus, the probability is:

$p = \frac{20}{21} = 0.952$

0.952 probability that a bag of flour passes inspection.

Item 3:

Probability of 0.025, thus, for 100 trials, 2.5 successes and 97.5 failures, and the odd is:

2.5:97.5, which, simplifying by 2.5, is 1:39.

Item 4:

59% probability that he will take the longest trail, thus 100 - 59 = 41% probability of him not tanking the longest trail, thus, the odds against him taking the longest trail is 41:59.

Item 5:

Probability of 0.56, thus, for 100 trials, 56 successes and 44 failures, and the odd is:

56:44, which, simplifying by 4, is 14:11.

Alisa is making bracelets with leather bands. each bracelet uses 7 3/4 inches of leather banding. she plans to make 4 bracelets.

Artyom0805 [142]

Each bracelet is $7 \frac{3}{4} inches$

Turn it into an improper fraction

Multiply 7 and 4 and add 3 which is over 4 which is $\frac{31}{4}$

Multiply by 4 | for each bracelet being made

$\frac{31}{4} * \frac{4}{1}$ $= \frac{124}{4}$

124÷4=31

Answer:

You need 31 inches to make all the braclets
