marissa [1.9K]

Answer:

Step-by-step explanation:

What we are expected to solve for that the problem did not expressly state is most likely the number of hours that you could ride for an amount of $65.

firstly we need to model the inequality (equation) for this scenario.

the constant fee= $3 additional fee for helmet

$3+15n\leq 65\\\\$

We can now solve for n since the above inequality satisfies the condition presented in the problem statement.

$3+15n\leq 65\\\\15n\leq65-3\\\\ 15n\leq 62$

Divide both sides by 15 to find n

$n\leq 62/15\\\\n\leq 4hrs -8min$

If pq = 23 and uv = 1/23, find the value of u×q×v×p. Explain which properties you used

zhannawk [14.2K]

Remember that multiplication is commutative, which means the order in which we multiply things doesn't matter.

The order of u × q × v × p (which we can abbreviate uqvp) isn't as important as the fact that we're multiplying all four values together. We could just as easily rewrite the expression as pquv, and it'd represent the same value.

To find this value then, we can simply multiply pq and uv - the values we already know - together.

If we start with the expression pq = 23, we can multiply either side by uv (taking advantage of the multiplication property of equality) to get

pquv = 23uv

And since we know that uv = 1/23, we can use the substitution property of equality to replace the uv on the right side with 1/23:

pquv = 23(1/23)

The inverse property of multiplication states that any number multiplied by its inverse (its reciprocal) gives us 1. 23 and 1/23 are reciprocals of each other, so 23(1/23) = 1, which means

pquv = 1

Finally, going back to the second paragraph, we can use the commutative property of multiplication to rearrange the left side of the equation, giving us the solution

uqvp = 1

Matthew purchased a washer and dryer for $2,885 using an 18-month deferred payment plan with an interest rate of 26.12%. What is

-Dominant- [34]

For a deferred payment plan no interest is accrued for the deferment period.

If $85 is made each month, then in 18 months, 18 * 85 = $1,530 must have been paid off from the balance owed.

Thus, the remaining balance after the deferment period is $2,885 - $1,530 = $1,355.

AveGali [126]

Answer:

208cats

Step-by-step explanation:

⅝=tongue

³/16=straw=39cats

⅝+³/16=13/16

meaning total number of cats is 16/16

If ³/16=39cats

16/16=?

39×16/3

=208cats

One-fourth of the residents of a particular community leave their garage doors unlocked when they go out to do an errand. The lo

Answer:

Required Probability = 0.625

Step-by-step explanation:

Given,

Probability of unlocked doors, P(U) = 0.25

Probability of locked doors, P(U') = 0.75

Probability of something being stolen when door is unlocked, P(S/U) = 0.05

Probability of something not being stolen when door is unlocked, P(S'/U) = 0.95

Probability of something being stolen when door is locked, P(S/U') = 0.01

Probability of something not being stolen when door is locked, P(S'/U') = 0.99\

probability of being stolen either door is locked or not,

P(S) =P(S/U).P(U) + P(S\U').P(U')

= 0.05 x 0.25 + 0.95 x 0.75

= 0.0125 + 0.0075

= 0.02

Probability that door was unlocked when while steeling can by given by

$P(U/S)\ =\ \dfrac{P(S/U).P(U)}{P(S)}$

$=\ \dfrac{0.05\times 0.25}{0.02}$

= 0.625

hence, the required probability is 0.625.
