what is 6⅓ + 5 3/10 =
Answer:
11 19/30
Step-by-step explanation:
Given 6⅓ + 5 3/10
Convert to improper fraction
= 19/3 + 53/10
Find the LCM
= 19(10)+3(53)/30
= (190+159)/30
= 349/30
= 11 19/30
Hence the sum of the fractions is 11 19/30

Suppose a new regulation that a maximum angle of a ramp for a wheelchairs is 8°. At least how long must the new ramp be? Round to the nearest tenth of a foot.
Answer:
The length of the ramp is at least 17.2 feet
Step-by-step explanation:
See attachment for the appropriate diagram.
The length of the ramp is represented with z
So, we have:
[tex]\theta = 8[/tex]
[tex]BC = 2.4[/tex]
Required
Find z
To find z, we make use of sine formula:
[tex]sin\theta = \frac{BC}{z}[/tex]
Make z the subject
[tex]z= \frac{BC}{sin\theta }[/tex]
So:
[tex]z= \frac{2.4}{sin(8)}[/tex]
[tex]z= \frac{2.4}{0.1392}[/tex]
[tex]z= 17.2ft[/tex]
The length is at least 17.2 feet
Kindred invested $38,976 into first company his investment decreased by 3.5% each years over the first 3 years. Which exponential decay model could use to determine the amount his investment will be worth if in continue to decrease at the same rate?
Answer:
35,025.08 x 0.965 ^ X = Y
Step-by-step explanation:
Given that Kindred invested $ 38,976 into First company, and his investment decreased by 3.5% each year over the first 3 years, to determine which exponential decay model could use to determine the amount his investment will be worth if it continues to decrease at the same rate the following calculation must be performed:
100 - 3.5 = 96.5
38,976 x 0.965 ^ 3 = 35,025.08
Thus, after 3 years of losses, the value of the account will be $ 35,025.08. In turn, if we wanted to determine the amount his investment will be worth if it continues to decrease at the same rate, the following equation should be applied:
35,025.08 x 0.965 ^ X = Y
In this case, X will be the number of years the investment has fallen, and Y will be the value of said investment after the years of decline.

As per quadratic equation, the solutions to the equation √(x² + 2x - 10) = √(x + 20) is x = - 6, 5.
What is a quadratic equation?"A quadratic equation is an algebraic equation of the second degree in x. The quadratic equation in its standard form is ax² + bx + c = 0, where 'a' and 'b' are the coefficients(a ≠ 0), x is the variable, and 'c' is the constant term."
The given quadratic equation is:
√(x² + 2x - 10) = √(x + 20)
⇒ (x² + 2x - 10) = (x + 20)
⇒ (x² + 2x - 10) - (x + 20) = 0
⇒ (x² + x - 30) = 0
⇒ (x² + 6x - 5x - 30) = 0
⇒ x(x + 6) - 5(x + 6) = 0
⇒ (x + 6) (x - 5) = 0
⇒ x = - 6, 5

Preston writes 3 songs in 2 days, working 7 hours each day. He spends the same amount of time on each song. How long does he spend on each song?
Answer:
Step-by-step explanation:
In 2 days he spends 2*7 = 14 hours total
He divides the number of hours on each song evenly
14 /3 = 4 2/3 hours on each song.
What is 2/3 of an hour?
2/3 * 60 = 120 / 3 = 40 minutes
Total time spent on each song 4 hours and 40 minutes
Answer:
3 songs =2 days working only 7 hour =7×2=14 hour
1 song =14/3hour.=4.6 hour
he spends 4.6 hour on each song
There are a total of 10 pigs and ducks in the barn. There are 36 legs in all (each pig has four legs and each duck has two legs). Use substitution to solve the linear system of equations and determine how many pigs, x and ducks, y there are. Express the solution as an ordered pair (x,y).
Answer: 8 pigs and 2 ducks.
1. (A) p + d = 10
2. (B) 4p + 2d = 36
3. Multiply equation (A) with -2; -2p minus -2d = -20
4. When subtracted from equation (B), this gives you.. 2p = 16, pigs = 8
5. Use this 8 to the second equation by substitution.. 2d = 4, ducks = 2
1. Building traveler loyalty is a key strategic factor for a popular vacation rental platform. Several factors can deter repeat bookings, one of which is cancellation by the owner of the property. The data science team observes that 35% of travelers who have not had a reservation cancelled by an owner return to the site for repeat bookings. Travelers with a reservation that WAS cancelled by an owner repeat book at a 20% rate. If owners cancel 8% of the time, what is the overall repeat booking rate?
2. The data science team also seeks to understand the impact on customer loyalty with respect toanother type of cancellation: traveler cancellations. The repeat booking rate for owner cancellations is 20%;for traveler cancellations, 28%; and no cancellation, 36%. If the overall repeat booking rate is 34%, and theprobability of an owner cancellation is 8%, what is the probability of a traveler cancellation?
Answer:
1. The overall repeat booking rate is 34.72%.
2. The probability of a traveler cancellation is 0.09 = 9%.
Step-by-step explanation:
Bayes Theorem:
Two events, A and B.
[tex]P(B|A) = \frac{P(B)*P(A|B)}{P(A)}[/tex]
In which P(B|A) is the probability of B happening when A has happened and P(A|B) is the probability of A happening when B has happened.
Question 1:
36% of 100 - 8 = 92%(not canceled)
20% of 8%(canceled). So
[tex]p = 0.36*0.92 + 0.2*0.08 = 0.3472[/tex]
The overall repeat booking rate is 34.72%.
Question 2:
We have that 34% is the sum of:
20% of 8%(repeat cancellation when the owner cancels).
28% of x(traveler cancelations).
36% of (100 - (8+x))%(no cancellation). So
[tex]0.2*0.08 + 0.28x + 0.36(1 - (0.08+x)) = 0.34[/tex]
[tex]0.016 + 0.28x + 0.36(0.92 - x) = 0.34[/tex]
[tex]0.016 + 0.28x + 0.3312 - 0.36x = 0.34[/tex]
[tex]0.08x = 0.3312 + 0.016 - 0.34[/tex]
[tex]x = \frac{0.3312 + 0.016 - 0.34}{0.08}[/tex]
[tex]x = 0.09[/tex]
The probability of a traveler cancellation is 0.09 = 9%.

Answer:
240 minutes
Step-by-step explanation:
If it's 40 minutes for just 5 papers, we need to figure how many minutes it would take to grade just 1. So you have to divide 40 by 5 which is 8. Then 8 time 30 which is 240.
