Write an equation for the total water usage, U, at the park this year in terms of x, the number of special events the park has hosted

Answers

Answer:

U = 16206 + 22.2x

Step-by-step explanation:

This year, water usage has increased by 20% for both regular days and special events.. Write an equation for the total water usage, U, at the park this year in terms of x, the number of special events the park has hosted

Solution:

Last year regular usage of water was 13505 gallons, where as it was 18.5 gallons per special event. Let us assume that there were x special invents, hence:

The total usage for last year = 13505 + 18.5x

This year, the total usage (U) increased by 20%, hence:

Total usage for this year (U) = total usage for last year + 20% of total usage for last year

U = (13505 + 18.5x) + 0.2(13505 + 18.5x)

U = 13505 + 18.5x + 2701 + 3.7x

U = 16206 + 22.2x

Ravi is 8 years older than nastasha the sum of their ages is 42 find their ages

Answers

Answer: Natasha is 17 and Ravi is 25

Step-by-step explanation:

Let n = Natasha’s age and r = Ravi’s age

We can write an equation then substitute: 42=n+r

We know that Ravi is 8 years older than Natasha, so Ravi’s age is equal to n+8. We can substitute that in, so 42= n+(n+8)

Simplify:

42=n+(n+8)

42= 2n+8

42-8=2n+8-8 (subtract 8 from both sides to isolate n)

34=2n

34/2=2n/2 (divide both sides by two)

17=n

Natasha is 17, and Ravi is 8 years older. 17+8= 25, Ravi is 25. You can double check by adding 25 and 17 together, which brings you back to 42 :]

Answer: 4'6 2'4

Step-by-step explanation:

In a certain video game, players earn bonus points after finishing a
level. The number of bonus points is based on how many seconds, t,
it takes the player to finish the level. The game uses the expression
-5.5 + 500+ 0.9t + (1 - 1.9t to determine the number of bonus points. .
Zahara finishes a level in 201 seconds. How many bonus points does she earn?

Answers

Answer:

If Zahara finishes a level in 201 seconds, she earns:

294.5 points

Step-by-step explanation:

To identify the number of points that Zahara obtained when she finished a level in 201 seconds, you must use the given expression:

-5.5 + 500+ 0.9t + (1 - 1.9t)

Where:

t = time in seconds.

As Zahara took 201 seconds to finish a level, we're gonna replace this value in the equation:

-5.5 + 500+ 0.9t + (1 - 1.9t)-5.5 + 500+ 0.9(201) + (1 - 1.9[201]) (we're not use the unit "seconds", because we don't need it in this calculation)-5.5 + 500+ 180.9 + (1 - 381.9)-5.5 + 500+ 180.9 - 380.9 (You can organize the numbers is you want)500 + 180.9 - 380.9 - 5.5294.5 points

As you can see, Zahara obtains 294.5 points if she finishes the level in 201 seconds.

C. (2x – 3)(x + 5) = 0

D. (2x + 5)(x – 3) = 0

Answers

C (2x-3)(x+5). I just know. Please give me the brainliest

Answer:

C. (2x – 3)(x + 5) = 0

Step-by-step explanation:

The equation in standard form should be 2x^2 + 7x - 15 = 0

Factored the expression is (2x - 3)(x + 5).

In order to find the factored portion, you must look for factors of the front number (2) to use in the front of the parenthesis and factors of the last number (-15) to go in the end.  

When we use the ones that we have above, it distributes to the overall end result.  

(2x - 3)(x + 5)

2x^2 - 3x + 10x - 15

2x^2 + 7x - 15

The two possible numbers that satisfy the given equation model are -8 and 10.

What is a expression? What is a mathematical equation? What is Equation modelling ?

A mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions. Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

Given is the successor of a number, when multiplied by the number decreased by 3 units, 77 is obtained.

Assume the number to be [x]. Its successor would be [x + 1]. Then, we can write -

(x + 1)(x - 3) = 77

Refer to the graph attached. The [x] - intercepts the solution. We get -

x = - 8

x = 10

Therefore, the two possible numbers that satisfy the given equation model are -8 and 10.

Con someone help me with questions 3 and 4

Answers

Answer:

t = 13 hours

The values will be equal in 10 years.

Step-by-step explanation:

Three

There are two ways to do this problem. I'll do it the simplest way -- which will benefit you most if you are about to take a physics class.

Follow these observations.

The difference of speed of these two cars is 70 - 65 = 5 mphThe distance travelled by the first car before the second one starts is 65 miles in 1 hour.  That comes about because Tom goes 65 miles before Michelle even starts. She starts exactly 1 hour after Tom and he has gone 65 miles in that time.She is going faster, but he is still moving. That's what makes the problem hard.Fortunately, you don't have to figure that out. You have all the information you need.

Solution

Time it takes to Catch Tom = distance to be made up / difference in speed

Distance to be made up = 65 miles

Difference in speed = 5 mph

Time taken for michelle to catch Tom = t

t = 65/5

t = 13 hours.

Solution Two

The distance is the same when Michelle catches Tom

d = r*t

Michelle's rate = 70 mph

Michelle's time = t

Tom's rate = 65

Tom's Time = t + 1

70 * t = 65(t + 1)

70 * t = 65*t + 65

70*t - 65*t = 65

5t = 65

t = 65/5 = 13

In thirteen hours, Michelle will catch Tom

One house increases by 10000 the other decreases by 5000. You could do it using the first method above, but in this case the second is actually easier.

Juan: 200000 + 10000*t

Tia  : 350000 - 5000t

When will the be equal (at what price and when?).

200000 + 10000t =350000 - 5000t         Divide by 1000

200 + 10t = 350 - 5t                                    Add 5t to both sides

200 + 10t + 5t = 350                                   Combine

200 + 15t = 350                                          Subtract 200 from both sides

15t = 150                                                      Divide by 15

t = 150/15

t = 10 years

There are four sixth graders and seven seventh graders in Elsa's chess club. Two members of the club will be chosen at random to attend a tournament with several other chess clubs. Elsa is using simulation to determine the experimental probability of randomly selecting two sixth graders. So, she places four red discs (to represent the sixth graders) and seven blue discs (to represent the seventh graders) in a bag. She randomly selects one disc from the bag, records the color, keeps the disc out, selects another disc and records it, and then returns both discs to the bag. Elsa does this twenty-five times.

Suppose that of 2000 students, 1100 take math, 500 take science, and 300 students take both math and science. What is the probability that a student selected at random takes math or science?

Answers

Answer:

4/5

Step-by-step explanation:

Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.

For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one is attached to the event. If it doesn't a value of zero is attached to the event.

probability that a student selected at random takes math or science = probability a student takes maths + probability a student takes science

probability a student takes maths = number of maths students / total number of students

probability a student takes science = number of science students / total number of students

(500 / 2000) + (1100 / 2000) = 1600/2000 = 4/5

A garden table and a bench cost 816 combined. The garden table costs 84 less than the bench. What is the cost of the bench?

Answers

Answer:

366

Step-by-step explanation:

A garden table and bench cost 816 when combined together

The garden table cost 84 less than the bench

Therefore the price of the bench can be calculated as follows

x + (x+84)= 816

2x+84= 816

2x= 816-84

2x= 732

Divide both sides by 2

x= 732/2

= 366

Hence the price of the bench is 366
