Last night game at the arena in Cleveland was 251 seats short of being filled to capacity. how many people attended the game?
1. The attendance at the Cleveland arena was 20,311 people.
2. The largest arena can seat 1,800 more people than the smallest arena.
3. The estimated seating capacity difference between the Atlanta and Los Angeles arenas is 1,300.
4. The total attendance for the sold-out games is 37,124 people.
5. The combined capacity of the Cleveland and Boston arenas is 6,186 people greater than the biggest college basketball arena.
1. **Last night's game in Cleveland:**
The attendance at the Cleveland arena last night was 20,562 - 251 = 20,311 people. This is because the arena was 251 seats short of being filled to its full capacity.
2. **Difference in seating capacities:**
The difference in seating capacities between the largest (Los Angeles) and smallest (New Orleans) arenas is calculated by subtracting the smaller capacity from the larger one: 20,300 - 18,500 = 1,800. Therefore, the largest arena can accommodate 1,800 more people than the smallest arena.
3. **Estimate of seating capacity difference (Atlanta and Los Angeles):**
The estimated difference in seating capacities between the Atlanta and Los Angeles arenas can be obtained by rounding the capacities to the nearest hundred, making the calculation easier. The rounded capacities are 20,300 and 19,000, resulting in an estimated difference of 1,300.
4. **Attendance at sold-out games:**
The total attendance for the sold-out games in Boston and New Orleans is the sum of their individual capacities: 18,624 + 18,500 = 37,124 people.
5. **Combined capacity of Cleveland and Boston vs. biggest college arena:**
The combined capacity of the Cleveland and Boston arenas is 20,562 + 18,624 = 39,186 people. Since this is greater than the capacity of the biggest college basketball arena (33,000), the combined capacity of the Cleveland and Boston arenas is 6,186 people greater.
In summary, the attendance at the Cleveland arena last night was 20,311 people. The largest arena can seat 1,800 more people than the smallest arena. The estimated seating capacity difference between the Atlanta and Los Angeles arenas is 1,300. The total attendance for the sold-out games in Boston and New Orleans is 37,124 people. The combined capacity of the Cleveland and Boston arenas is 6,186 people greater than the biggest college basketball arena.

For this case we have:
We locate the given points on the negative axis of the x coordinate
We shadow the region between both points
The shaded region will be the difference or distance between both numbers.
Algebraically, the difference is given by:

Answer:
[tex]Distance = 9\\[/tex]

The distance between -13 and -4 on a number line is the absolute value of their difference, which is 9 units.
Explanation:The distance between two points on a number line is the absolute difference between those points. In this case, the points are -13 and -4. To calculate the distance, we subtract these values in such a way that we get a positive result.
So, we subtract -4 from -13, which is the same as adding 4 to 13, i.e.,: -13 - (-4) = -13 + 4 = -9.
However, distance cannot be negative, so we take the absolute value of -9, which is 9. Therefore, the distance between -13 and -4 on the number line is 9 units. None of the options provided seem to correctly represent this result.

Make sure it's fully reduced.
2 - x = 5/8
Isolate the x. Note the equal sign. What you do to one side, you do to the other.
First, subtract 2 from both sides
2 (-2) - x = (5/8) - 2
-x = 5/8 - 2
Make sure they have the same denominator. Remember that what you multiply to the denominator, you multiply the numerator:
-x = 5/8 - 16/8
-x = - 11/8
Isolate the x. Divide -1 from both sides
(-x)/-1 = (-11/8)/-1
x = 11/8
11/8 is your answer for x

The solution is (x,y)=(2,5)
(you can check by plugging 2 for x and 5 for y and both equations will work out)
If f(x) is a linear function, what is the value of n?
m = (-10 + 25)/(-1 + 4) = 15/3 = 5
so
5 = (20 + 10)/(n + 1)
5(n+1) = 30
5n + 5 = 30
5n = 25
n = 5
Answer
n = 5
Answer:
value of n is 5
Third option is correct.
Step-by-step explanation:
Let the equation of the linear function is y = mx + b
From the given table, we have two points (-4,-25) and (-1,-10)
The slope of the line containing these two points is
[tex]m=\frac{y_2-y_1}{x_2-x_1}\\\\m=\frac{-10+25}{-1+4}\\\\m=\frac{15}{3}\\\\m=5[/tex]
Now, put m = 5, x = -4 and y = -25 in the equation y = mx+b
[tex]-25=5\cdot(-4)+b\\\\-25=-20+b\\\\b = -5[/tex]
Therefore, equation of linear function is [tex]y=5x-5[/tex]
Now, put x = n and y =20
[tex]20=5n-5\\\\5n=25\\\\n=5[/tex]
Therefore, the value of n is 5

Rob spent 25%, percent more time on his research project than he had planned. He spent an extra h
hours on the project.
Which of the following expressions could represent the number of hours Rob actually spent on the project?
Rob spent 25% extra percent on his project than the had planned.
Let us assume total number of hours spent x hours.
Given that he spent an extra h hours on the project
So, we could say 25% of x is h.
0.25 x = h.
Dividing both sides by 0.25.
We get 0.25h/0.25 = h/0.25.
x = h/0.25.
Let us convert 0.25 into fractions.
0.25 = 25/100 = 1/4.
Therefore,
x = h/1/4 = 4h.
Therefore, Rob planned 4h hours.
He spent h hours extra.
So, he spent total 4h+h = 5h hours total.
Therefore, 5h expressions could represent the number of hours Rob actually spent on the project.twice c is at least 19
2c ≥ 19
We can treat this inequality like a standard algebraic equation.
Divide both sides by 2.
c ≥ 9.5
4(b-6)+19 simplify the expression
Step 1. Expand
4b - 24 + 19
Step 2. Collect like terms
4b + (-24 + 19)
Step 3. Simplify
4b - 5
The answer is 4b - 5 :)
Write to explain how you can break apart 16 x 34 into four simpler multiplication problems
Think of the tens and the units separately:
16 x 34
= (10 + 6)(30 + 4)
Then we can distribute and get:
10(30 + 4) + 6(30 + 4)
And then further to get:
(10 x 30) + (10 x 4) + (6 x 30) + (6 x 4)
Each of these multiplications is easy enough to do in your head:

16×34 can be rewritten as (10+6)×(30+4) for simpler multiplication.
The given numerical expression is 16×34.
What is multiplication?Multiplication is an operation that represents the basic idea of repeated addition of the same number. The numbers that are multiplied are called the factors and the result that is obtained after the multiplication of two or more numbers is known as the product of those numbers.
Here, 16×34 can be written as
Method 1:
(10+6)×(30+4)
Using distributive property we get
10(30+4)+6(30+4)
= 300+40+180+24
= 544
Method 2:
16×(30+4)
Method 3:
(10+6)×34
Therefore, 16×34 can be rewritten as (10+6)×(30+4) for simpler multiplication.

The Sugar Sweet Company is going to transport its sugar to market. It will cost $6300 to rent trucks, and it will cost an additional $225 for each ton of sugar transported.
Let C represent the total cost (in dollars), and let S represent the amount of sugar (in tons) transported. Write an equation relating C to S, and then graph your equation using the axes below.
C=225S+6300
This is because the total cost would be equal to all of the stuff combined. Since it takes 225 to transport 1 ton of sugar, it would be multiplied with s

Paloma decided to divide 1,292 by 31 using partial quotients. She uses 30 as her first partial quotient. Which are the partial quotients Paloma should show in her work?
A) 30,10
B) 30,10,1
C) 10,10,10,1
D) 10,10,10,10,1
Answer:Partial quotients Paloma should show in her work are B) 30,10,1.
Step-by-step explanation:
Given : Paloma dividing 1292 (dividend) by 31 (divisor) using partial quotients.
so the easy multiples of 31 are as 31×2=62 ,31×3=93,31×10=310....so on
if she uses 30 as her first partial quotient then 31×30=930, so after subtracting 930 from 1292 we get 362 as new dividend then 31×10=310 is the easiest multiple of 31 so that 362-310=52 as new dividend ,then 31×1=31 subtracting this from 52 gives 52-31=21 which is the remainder.
Therefore, Partial quotients Paloma should show in her work are 30,10 and 1.
