Answer:
156.6 meters squared
Step-by-step explanation:
There are 3 triangles for the sides. The area for a triangle is one half base times height. So we are doing one half of 9 times 9. This is 40.5. Since there are 3 of them we can just multiply 40.5 times 3 to get 121.5. And now to solve for the base triangle, it is one half of 9 times 7.8. We get 35.1. Now add together 121.5 and 35.1. We get 156.6. Now since this is surface area it is meters squared.
SOLVE FOR X TO THE NEAREST TENTH
Answer:
x = 8.8
Step-by-step explanation:
First, you have to solve the side length for the smaller triangle.
[tex]c= \sqrt{ a^{2} +b^{2} }\\c= \sqrt{5^{2}+4^{2} } \\\\c=\sqrt{25+16} \\c=\sqrt{41} \\c= 6.4\\[/tex]
Now for the bigger square.
[tex]c= \sqrt{ a^{2} +b^{2} \\} \\c = \sqrt{6.4^{2} +6^{2} } \\c= \sqrt{40.96+36} \\c= \sqrt{ 76.96}\\c= 8.77\\[/tex]
Rounded to the nearest tenth = 8.8

The Boston Red Sox had 949 runs in their 2004 season. In their 2015 season, they had 748 runs. Find the rate of change in runs.
Answer: -18.27 per year
Step-by-step explanation:
The difference in years is:
= 2015 - 2004
= 11 years
In those 11 years, the runs decreased from 949 to 748.
The total decrease is:
= 949 - 748
= 201 runs
The rate of change is:
= 201 / 11
= 18.27 per year
Since it is reducing, the rate is:
= -18.27 per year

The members of the city cultural center have decided to put on a play once a night for a week. Their auditorium holds people. By selling tickets, the members would like to raise $ every night to cover all expenses. Let d represent the number of adult tickets sold at $. Let s represent the number of student tickets sold at $ each. If all seats are filled for a performance, how many of each type of ticket must have been sold for the members to raise exactly $? At one performance there were times as many student tickets sold as adult tickets. If there were tickets sold at that performance, how much below the goal of $ did ticket sales fall?
Answer:
a) At $3,300 for 600 seats, the average price per seat is 3300/600 = $5.50. The mix of tickets that results in that average can be found using an X diagram as shown below. The numbers on the right are the differences along the diagonals. When they are multiplied by 2, they add to 600. This shows that the required sales for revenue of $3,300 are
200 adult tickets
400 student tickets
b) When 3 student tickets are sold for each adult ticket, the average seat price is
(3*$4.50 +7.50)/4 = $5.25
Then the shortfall in revenue is ...
$3,300 -480*$5.25 = $780
what is -2 x 3 i do not understand this and this is my last problem
Answer:
-6
Step-by-step explanation:
if they were both positive numbers, it would be 6. But when you multiply a negative by a positive, the answer is negative.
Answer:
-6
Step-by-step explanation:
When you multiply a positive number by another positive number, you will always get a positive number as your answer. Same thing for negative. If you multiply a negative by a negative, you will always get a positive. However, when you multiply a negative by a positive, you will always get a negative number.
Since you know this, you can multiply 2 by 3, which is 6. Because 2 is negative and 3 is positive, you know that the answer must be negative. Therefore, you add the negative symbol to 6, giving you -6.
I hope this isn't too confusing. Please let me know if you have any more questions. Good luck!

18. State the slope and y-intercept of each linear equations.
a. 6(x + y) = 3(x - y)
b. 2(x + y) = 5(y + 1)
c. 5x + 10y - 20 = 0)
Answer:
a. m = -1, y-int = 0
b. m = 2/3, y-int = -5/3
c. m = -1/2, y-int = 2
Step-by-step explanation:
-Expand equations on both sides.
-Make 'y' the subject by collecting like terms and moving everything to the right, e.g. y = ...
-Slope is the number in front of x.
-Find y-intercept by letting x = 0 and solve the equation.

what is the slope of the line through the points (-2,-1) and (4,3)
Answer:
2/3
Step-by-step explanation:
the slope is change of y divided by change of x
[tex]m = \frac{2}{3} [/tex]
Step-by-step explanation:-
[tex]( - 2, - 1) = (x {1} ,y {1}) [/tex]
[tex](4,3) = (x{2} ,y{2} )[/tex]
BY USING SLOPE OF LINE FORMULA
[tex]m = \frac{y2 - y1}{x2 - x1} [/tex]
[tex]m = \frac{(3 - ( - 1))}{(4 - ( - 2))} [/tex]
[tex]m = \frac{(3 + 1)}{(4 + 2)} [/tex]
[tex]m = \frac{4}{6} [/tex]
[tex]m = \frac{2}{3} [/tex]
