Average attendance at a school’s basketball games increased from 1,000 to 1,500 last year. One student said that represented a 150% increase. Explain the student’s mistake. What is the actual percent increase?
Answer:
50%
Step-by-step explanation:
Since 1,000 is 100% of the attendance, 500 is half of 1,000 meaning it's 50%.
I think the student added 50% and 100%, they could have also divided 1,500 by 10.
The actual percent increase would be equal to 50 percent.
How to find the percentage from the total value?Suppose the value of which a thing is expressed in percentage is "a'
Suppose the percent that considered thing is of "a" is b%
Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means). Thus, that thing in number is [tex]\dfrac{a}{100} \times b[/tex]

y = x + 5
y = -2x - 4
what are the y and x values please
Answer:
x=-3, and y=2
Step-by-step explanation:
Since both equations are equal to y, set them equal to each other and solve for x, that way you can solve for y:
x+5=-2x-4
3x+5=-4
3x=-9
x=-3
Plugging in x=-3 into one of the original equations:
y = x + 5
y = -3 + 5
y = 2
Therefore, x=-3 and y=2. You can also write as the ordered pair (-3,2) since that's where the two equations would intercept on a graph.
The elevator at the state capital has a maximum weight capacity of 2000 pounds. If there are 3
people already on the elevator with a combined weight of 428 pounds, write an inequality to express
the possible weights that may be added to the elevator,
Part A: Define your variable
Part B: Write the inequality
Part C: Describe what your inequality looks like on a number line. Be sure to include whether the
circle is open or closed and the direction the line is shaded.
Answer:
Step-by-step explanation:
Maximum capacity of the elevator = 2000 pounds
Combined weight of the elevator = 428 pounds
A). Let the possible weights that can be added to the elevator = w pounds
B). Therefore, inequality representing this situation will be,
428 + w < 2000
C). By solving the given inequality,
(428 + w) - 428 < 2000 - 428
w < 1572 pounds
Now we draw this inequality on a number line.

What was his mean test score?
Answer:
85
Step-by-step explanation:
Scott took 7* math tests in one semester. His scores were 89 , 73 , 84 , 91 , 87 , 77 , 94.
Find the mean. To solve for the mean, add all the scores together, and divide by the amount of tests he took:
(89 + 73 + 84 + 91 + 87 + 77 + 94)/7
(595)/7 = 85

A cone has a height of 10 meters and a diameter of 20 meters. What is its volume?
Use ≈ 3.14 and round your answer to the nearest hundredth
Answer: 235.5 cm³
Step-by-step explanation: Volume of a cylinder is the area of the circular base times the height of the cylinder:
V = π r² h
Given r = 5 cm and h = 3 cm:
V = (3.14) (5 cm)² (3 cm)
V = 235.5 cm³

Answer:
18π cm²
Step-by-step explanation:
The area of the shaded region = Area of Sector
Radius, r =
The value of θ = 80°
Recall :
Area of Sector :
A = θ / 360 * πr²
A = (80 / 360) * π * 9²
A = 0.222222 * π * 81
A = 18π cm²

Terry has 3 pairs of pants (black, khaki, and brown) and 4 shirts (yellow, red, blue, and white). He does not care which colors he wears together. How many different outfits can Terry make
Answer: 12 different outfits
===========================================================
Explanation:
We simply multiply the values given to us. Think of a table that has 3 rows and 4 columns. The rows represent the different colors of pants Terry can wear. Each column is a different color shirt. Since we have 3 rows and 4 columns, we have 3*4 = 12 cells inside the table. Each cell represents a combination of pants and shirt colors. This means there are 12 different outfits possible.
Answer:
12
Step-by-step explanation:
if he has 3 pairs of pants and doesn't care what colors he wears then each shirt can go with the pants once and since there a 4 shirts and three pants then 3 times 4 =12

Answer:
x = 30
ABC = 90
ACB = 30
Step-by-step explanation:
We know that if we add the 3 angles of a triangle together, it will come out to be 180 degrees, so..
60 + x + 3x = 180 subtract 60 from both sides and simplify
4x = 120 divide both sides by 4
x = 30
ABC = 3x
ABC = 3(30)
ABC = 90
