In the first week of July, a record 1,060 people went to the local swimming pool. In the second week, 100 fewer people went to the pool than in the first week. In the third week, 140 more people went to the pool than in the second week. In the fourth week, 252 fewer people went to the pool than in the third week. What is the percent decrease in the number of people who went to the pool over these four weeks?
(Can I have Brainlist?)
Answer:
10%
Step-by-step explanation:
The following information can be gotten from the question regarding the number of people that went to the swimming pool are:
First week of July = 1020
Second week = 1020 - 100 = 920
Third week = 920 + 130 = 1050
Fourth week = 1050 - 132 = 918
The percentage decrease over the four weeks will be:
= (1020 - 918)/1020 × 100
= 102/1020 × 100
= 10%

What can be concluded about the line represented in the table? Check all that apply.
X-6,2,8
Y-7,-3,0
The slope is 2.
The slope is 1/2.
The y intercept is 4.
The y intercept is 8
The points (-2,-5) and (8,0) are also on the line
The points (-5,-2) and (1,10) are also in the line.
Answer:
The slope is 1/2The points (-2,-5) and (8,0) are also on the lineStep-by-step explanation:
According to the table there are ordered pairs:
(-6, - 7), (2, - 3), (8, 0)Find the slope using two points:
m = (- 3 - (-7)) / (2 - (-6)) = 4/8 = 1/2Use one point to complete the equation:
y - (-7) = 1/2(x - (-6))y + 7 = 1/2x + 3y = 1/2x - 4So the slope is 1/2 and the y-intercept is (0, - 4)
Verify the points (-2, -5), (- 5, -2), (1, 10):
-5 = 1/2(-2) - 4 ⇒ - 5 = - 1 - 4 ⇒ - 5 = - 5, yes-2 = 1/2(-5) - 4 ⇒ - 2 = - 2.5 - 4 ⇒ - 2 = - 6.5, no10 = 1/2*1 - 4 ⇒ 10 = 0.5 - 4 ⇒ 10 = - 3.5, noNow, correct answer choices are:
The slope is 1/2The points (-2,-5) and (8,0) are also on the line-

the sum of 16 numbers is 240.The average of 6 of those numbers is 10. the average of the remaining numbers is
Answer:
18
Step-by-step explanation:
If the average of 6 numbers is 10, then the sum of those 6 numbers is:
6 x 10 = 60
To calculate the sum of the remaining 10 numbers, subtract 60 from the total sum of all the numbers:
240 - 60 = 180
Therefore, the average of the 10 remaining numbers:
180 ÷ 10 = 18

The members of the city cultural center have decided to put on a play once a night for a
week. Their auditorium holds 600 people. By selling tickets, the members would like to raise $3,300
every night to cover all expenses. Let d represent the number of adult tickets sold at $7.50. Lets
represent the number of student tickets sold at $4.50 each. If all 600 seats are filled for a
performance, how many of each type of ticket must have been sold for the members to raise exactly
$3,300? At one performance there were two times as many student tickets sold as adult tickets. If
there were 300 tickets sold at that performance, how much below the goal of $3,300 did ticket sales
fall?

Which relation is a function?
Answer:
the frst one s the answer
Step-by-step explanation:
t s a functon becuase all of the other ones have more than one pont on the lne and that one doesn't.
The relation shown in graph (A) is a b because the ordered double satisfies the condition of the function option (A) Is correct.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
It is given that:
The ordered double (x, y) is shown in the graphs.
As we know, from the definition of the function, they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
From the graph, the ordered double satisfies the condition of the function.
Thus, the relation shown in graph (A) is a b because the ordered double satisfies the condition of the function option (A) Is correct.

The purpose of each of the equations is to express the total cost of the described purchase. If x is the cost of a hamburger, then the cost of two hamburgers is 2x. Likewise if y is the cost of a drink, then the cost of 5 drinks is 5y. The total cost of 2 hamburgers and 5 drinks will be ...
2x +5y
This value is said to be $23, so the appropriate equation for this relation is ...

What is the equation of this line written in slope-intercept form?
y − 5/2 = −2(x+1)
A) y = −2x − 9/2
B) y=−2x+12
C) y = −2x + 7/2
i think you had a problem in number B which it's suppose to be 1/2 so the correct answer is B
Step-by-step explanation:
.
The equation of this line, y − 5/2 = −2 (x+1) written in slope-intercept form, is y = -2x + 1/2.
What is a line?An object having an endless length and no width, depth, or curvature is called a line. Since lines can exist in two, three, or higher-dimensional environments, they are one-dimensional things.
Given:
The equation of a line in slope intercept form,
y − 5/2 = −2 (x+1)
Simplify the above equation,
y - 5 / 2 = -2x - 2
y = -2x - 2 + 5/2
y = -4x - 4 + 5 / 2
2y = -4x + 1 or y = -2x + 1/2

A restaurant receives a shipment of 5,000 ketchup packets. In one week, they use 1,779 packets. The next week, they use 2,415 packets. How many ketchup packets does the restaurant have left?
Answer:
806 ketchup packets
Step-by-step explanation:
5000-1779=3221
3221-2415=806
The restaurant has 806 ketchip packets left
Answer:
5,806
Step-by-step explanation:
Because they got there 5,000 packets they subtracted 1,779 packets
5,000-1,779=3,221
Next remember they get 5,000 packets each week so then you add 5,000 to 3,221
3,221+5,000=8,221
next 2,415 packets were used so subtract 8,221 bu 2,415
8,221-2,415=5,806 so there's your answer

Kiara had the following car expenses last year: $3060 in car payments; $94 for license
and registration: $128 in tax; $1080 for insurance; $290 for parking; $398 for wear and
tear, $1520 for maintenance; and $930 for gas. If she drove 12,500 miles last year, what
was her average cost per mile?
Average cost per mile is $0.6
How to calculate the average cost per mile?To calculate the average cost per mile that Kiara had to pay, we perform the following operations:
We add up all the payments Kiara made related to her car.
$3,060 + $94 + $128 + $1,080 + $290 + $398 + $1,520 + $930 = $7,500Later we divide the total value, in the number of miles traveled by Kiara

Answer:
2.1
Step-by-step explanation:
Here we will simplify the ratio 30:15 for you and show you how we did it.
To simplify the ratio 30:15, we find the greatest common divisor of 30 and 15, and then we divide 30 and 15 by the greatest common divisor.
The greatest common divisor that you can use to simplify 30:15 is 15. Which means the answer to ratio 30:15 simplified is: 2.1
