Answer:

$5750

Step-by-step explanation:

Property damage insurance = $20,000

Comprehensive insurance = $5,000

Deductible = $500

Amount of Property damage caused by him by hitting a parked car = $4,500

Amount of Damage caused to his own car = $1,750

Since, the property damage of $4500 is within the property damage insurance limit of $20,000 and own damage of $1,750 is also within the comprehensive insurance limit of $5000, he'll be paid the entire amount excluding the compulsory deductible of $500.

So,

The amount paid by the insurance company to fix both cars = 4500+1750 - 500

= 6250 - 500

= $5750

The insurance will cover a total of $5,750 for the damages caused by Saheel's accident. It will completely cover the $4,500 worth of damage to the parked car that he hit, and will cover $1,250 of the $1,750 damage to his own car after the deductible.

In this case, Saheel has coverage for both property damage ($20,000) and comprehensive and collision insurance ($5,000 with a $500 deductible). When he slid on ice and hit a parked car, causing $4,500 worth of damage, his property damage insurance will cover this cost since it is under the $20,000 limit.

As for the $1,750 damage to his own car, his comprehensive and collision insurance can cover this after he pays the $500 deductible. So, his insurance will pay $1,250 ($1,750 - $500 deductible) towards the repair of his own car.

Therefore, the total money that the insurance company will pay to fix both cars would be $5,750 ($4,500 for the parked car's damages and $1,250 for Saheel's car damages after deductible).

Answer:

17 seconds

Step-by-step explanation:

The rescue helicopter travels down for 100 seconds at a speed of 10.5 feet per second.

So, the distance it covered = 100(10.5) = 1050 feet.

It then travels directly up for 150 seconds at a speed 5.2 feet per second.

So, the distance = 150(5.2) = 780 feet

Now, the distance from sea level = 1050 - 780 = 270 feet.

It will reach this distance with a maximum speed of 15.8 feet per second.

Hence, the time required to reach this distance = [tex]\frac{distance}{speed}[/tex]

= [tex]\frac{270}{15.8}[/tex]

Answer:

The answer to linear equation 9t=-3 is t = - (1/3)

Step-by-step explanation:

9t=-3

Solving for t: Dividing both sides of the equation by 9:

9t/9=-3/9

t=-(3/9)

Simplifying the fraction on the right side of the equation dividing the numerator and denominator by 3:

t = - (3/3) / (9/3)

t = - (1/3)

Answer:

[tex]x+y=12[/tex]

[tex]21.50x+14.75y=204[/tex]

Step-by-step explanation:

Let x be the number of adult tickets and y be the number of children's tickets.

We are given that there are total 12 people. Therefore, we can set:

[tex]x+y=12[/tex]

Moreover, we are given that an adult ticket costs $21.50 and a child's ticket costs $14.75, therefore, cost of x adult tickets will be [tex]21.50x[/tex] and cost of y children's ticket will be [tex]14.75y[/tex]. We can form the second equation by setting the total cost of tickets as:

[tex]21.50x+14.75y=204[/tex]

Therefore, the required system of equations that could be used to find x and y will be:

[tex]x+y=12[/tex]

[tex]21.50x+14.75y=204[/tex]

Answer:

[tex]x+y = 12[/tex]

[tex]21.50x+14.75y=204.00[/tex]

Step-by-step explanation:

Given :

A local amusement park charges $21.50 per daily adult ticket and $14.75 per daily child's ticket.

Group of 12 people paid $204.00 for tickets.

To Find : System of equations could be used to find x, the number of adult tickets purchased, and y, the number of children's tickets purchased.

Solution :

Since group contains 12 people so no. of tickets are 12 .

Let out of 12 people no. of adults's tickets  are x.

Let out of 12 people no. of children's ticket are y .

⇒[tex]x+y = 12[/tex]

Since charge of one adult ticket = $21.50

So, charge of x adult tickets = $21.50 x

Since charge of one child ticket = $14.75

So, charge of y children tickets =$14.75 y

And we are given that total amount paid by these 12 people = $204.00

Thus [tex]21.50x+14.75y=204.00[/tex]

Hence , System of equations could be used to find x, the number of adult tickets purchased, and y, the number of children's tickets purchased:

[tex]x+y = 12[/tex]

[tex]21.50x+14.75y=204.00[/tex]

Answer:

A) 210

Step-by-step explanation:

The percentage of students who have a cell phone plan with company x is student with plan x over total.The total is 130

P(x) = 70/130

The number of students with cell phone  company x is  found by multiplying the total number of students times   the percentage of students with company x

Students with company x = total * P(x)

                                          = 390 * 70/130

                                             = 210

Answer:

A) 210

Step-by-step explanation:

70 students have company X, out of the sample size 130. This forms the fraction 70/130.

n students have company X, out of the population 390. The n is simply a placeholder for a number. This forms the fraction n/390

Equate the two fractions, cross multiply, then divide both sides by 130 to solve for n

Doing all that gives us the following

70/130 = n/390

70*390 = 130*n ..... cross multiply

27300 = 130n

130n = 27300

130n/130 = 27300/130 ...... divide both sides by 130

n = 210

Out of the entire population, the best approximation to the number of students who have company X is 210 people.

23.3% ps the 3 is reapeating

Final answer:

The probability that Ari will select a sold-out item is 7/30 or approximately 23.33%.

Explanation:

The question asks about the probability that Ari will select an item that is already sold out from a candy machine with a certain configuration and number of sold-out items. To calculate this probability, we need to know the total number of items in the machine and how many are sold out.

There are five rows with six items each, giving a total of 30 items. With seven items sold out, there are 30 - 7 = 23 items available for purchase. The probability of selecting a sold-out item is the number of sold-out items divided by the total number of items. In this case, it's 7/30, which simplifies to 7/30.

So, if Ari randomly pushes a button on the candy machine, the probability that he will select an item that is already sold out is 7/30, or approximately 23.33%.

Answer: 80%

15 are on the council, so 75-15 = 60 are not on the council. Therefore, 60/75 = 0.80 = 80% of the students aren't on the council.

An alternative way to find this answer is to compute 15/75 = 0.20 = 20% showing that 20% of the students are on the council, so 100% - 20% = 80% are not on the council.

To find the percent of students not on the student council, subtract the number of students on the council from the total number of students and calculate the percentage.

To find out what percent of the students are NOT on the student council, we need to subtract the number of students who are on the student council from the total number of students and then calculate the percentage.

Number of students on the student council: 15

Total number of students: 75

Number of students NOT on the student council: 75 - 15 = 60

Percentage of students NOT on the student council: (60/75) * 100 = 80%
