Answer:
36
Step-by-step explanation:
There are several ways to find area of triangle from vertex coordinates, the easiest is: (x₁*(y₂-y₃) + x₂*(y₃-y₁) + x₃*(y₁-y₂)) / 2
Area = ((-1)*(-6 - -6) + (-6)*(-6 - 2) + (3)*(2 - -6)) / 2
= (0 + 48 + 24) / 2
= 72/2
= 36

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?
Answers
x + y = 500 and 7.5x + 4.5y = 2550
We can use substitution to solve for x and then plug it back into any equation and find y.
y = 500 - x
7.5x + 4.5 (500 - x) = 2550
7.5x + 2250 - 4.5x = 2550
3x = 300
x = 100 adults
100 + y = 500 → y = 400 students
To answer your second question, we have two new equations:
2x = y (This may be confusing, but since there were more student tickets sold, it is the larger number.)
x + y = 300
We can rewrite the first equation and add them together:
2x - y = 0
x + y = 300
3x = 300
x = 100 adults
100 + y = 300 y = 200 students
The money earned from these 300 people is 100 * 7.5 + 200 * 4.5 = 750 + 900 = $1650.
$2550 - $1650 = $900
The 300 tickets sold had a $900 fall in ticket sales.
Hope this helps!

Well its actually 4.4 but if you round down its 4 centimeters and 5 feet equals 152.4 so that minus 148 is 4.4
Answer:
Step-by-step explanation:
1 foot is 12 inches

Answers
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
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?
Answers
(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%

was her average cost per mile?
Answers
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:
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:
