There are 17 rows of seats in a cinema. There are 22 seats in each row. A film was shown in the cinema on friday night. Each ticket for a film cost £7.50. The sale of the tickets that night made was £2587.50
Answer:
29
Step-by-step explanation:
Here is the full question
There are 17 rows of seats in a cinema. There are 22 seats in each row. A film was shown in the cinema on friday night. Each ticket for the film cost £7.50
The sale of tickets for that night made £2587.50
How many tickets were not sold
Total number of seats = 17 x 22 = 374
Number of tickets sold = £2587.50 / £7.50 = 345
So 345 people filled 345 seats
Unoccupied seats = 374 - 345 = 29

- 12
-41
Answer:
>
Step-by-step explanation:
-12 is closer to 0 than -41 would be therefore -12>-41.
Answer:
>
Step-by-step explanation:
Looking at a number line, -41 is farther from 0 than -12.
See the image below.
The farther left a number is on a number line, the smaller it is.
The farther right a number is on the number line, the larger is it.
So:
-12 > -41

I need the value of x. 10x + 4 - 2x = 6x + 9 + 7
Answer:
x = 6
Step-by-step explanation:
Answer:
x=6
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
10x+4−2x=6x+9+7
10x+4+−2x=6x+9+7
(10x+−2x)+(4)=(6x)+(9+7)(Combine Like Terms)
8x+4=6x+16
8x+4=6x+16
Step 2: Subtract 6x from both sides.
8x+4−6x=6x+16−6x
2x+4=16
Step 3: Subtract 4 from both sides.
2x+4−4=16−4
2x=12
Step 4: Divide both sides by 2.
2x=12
Benjamin decides to treat himself to breakfast at his favorite restaurant. He orders chocolate milk that costs \$3.25$3.25dollar sign, 3, point, 25. Then, he wants to buy as many pancakes as he can, but he wants his bill to be at most \$30$30dollar sign, 30 before tax. The restaurant only sells pancakes in stacks of 444 pancakes for \$5.50$5.50dollar sign, 5, point, 50. Let SSS represent the number of stacks of pancakes that Benjamin buys.
Answer:
4 stacks of packages
4 * 4 = 16 pieces of pancake
Step-by-step explanation:
Maximum amount to spend ≤ $30
Milk chocolate = $3.25
Pancakes per stack = 5.50 (sold in stacks of 4)
Let number of stacks = s
In equality terms :
3.25 + 5.50s ≤ 30
5.50s ≤ 30 - 3.25
5.50s ≤ 26.75
s ≤ 26.75 / 5.50
s ≤ 4.86
Hence, 4 stacks of pancakes can be purchased
Answer:
3.25+5.50S<30
Step-by-step explanation:
Benjamin can afford at most 16 pancakes

Answer:
6(a -2)(7a +2)
Step-by-step explanation:
Removing a common factor of 6 can make the quadratic factors easier to find.
= 6(7a^2 -12a -4)
We want to find factors of (7)(-4) that have a total of -12. It doesn't take much search to see they are (-14)(2), so the expression can be written as ...
= 6(7a^2 -14a +2a -4) = 6((7a^2 -14a) +(2a -4)) . . . . rewrite 'a' term; group pairs
= 6((7a(a -2) +2(a -2)) . . . . factor pair groups
= 6(a -2)(7a +2) . . . . . . . . finish factoring
Jennifer buys 4.25 pounds of gummy worms for $2.96 per pound and 0.5 pounds of jaw
breakers for $4.95 per pound. Jennifer gives the clerk $20.00. If there is no sales tax on these
items, how much change should she receive?
In money form!
Answer:
$4.94
Step-by-step explanation:
Gummy worms cost $2.96 per lb, and she bought 4.25 lbs, so:
2.96 * 4.25 = $12.58 spent in gummy worms
Jaw breakers cost $4.95 per lb, and she bought 0.5 lbs, so:
4.95 * 0.5 = $2.48 spent in jaw breakers
Adding the gummy worms and the jaw breakers, she spent:
12.58 + 2.48 = 15.06 in Total
She gave the clerk $20.00, but she only spent only $15.06, so the clerk gave her back the difference:
20 - 15.06 = $4.94 is the change that she received

Find the value of x to the nearest degree.
Answer: x = 58°
Step-by-step explanation:
Sine = opposite leg ÷ hypotenuse
We need to find the hypotenuse first with the Pythagorean theorem.
a² + b² = c²
5² + 8² = c²
25 + 64 = c²
89 = c²
√c² = √89
c = 9.43398
c ≈ 9.43
Sine = opposite leg ÷ hypotenuse
Opp. leg - 8
Hypotenuse - 9.43
To find this, you have to use the calculator
Make sure the calculator is on scientific
If your calculator is on your computer and in full screen, find 8 ÷ 9.43 and then click sin⁻¹, you should get 58.03334
If your calculator is on your computer in mini screen, find 8 ÷ 9.43. This time, click the arrow that looks smth like this: ↑
When you do that, you should be able to see sin⁻¹, so you click that and you'll also get 58.03334
58.03334 ≈ 58
x = 58°

Describe what it means for something to be continuous.
Answer:
a continuous function is a function that does not have any abrupt changes in value, known as discontinuities. If not continuous, a function is said to be discontinuous.
Step-by-step explanation:
got me a 100 in the journal activity
A function is continuous if the graph of function is an unbroken curve; that is, the graph has no holes, gaps, or breaks.
What is mean by Function?A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
We have to given that;
To describe means for something to be continuous.
Now, We know that;
A function is continuous at a point, if it must be defined at that point, its limit must exist at the point, and the value of the function at that point must equal the value of the limit at that point.
Thus, A function is continuous if the graph of function is an unbroken curve; that is, the graph has no holes, gaps, or breaks.

Given : Beth owes 17,000 on her car loan. The interest rate on her loan is 4.25% She will be paying this loan off for 4 years.
To find : How much will she pay altogether?
Solution :
Using compound interest formula,
A = P(1 + r)
Where A is the amount
P is the principle P=17,000
P is the rate r=4.25%=0.0425
t is the time t= 4 years
Substitute the value,
Therefore, She has to pay $20078.7 amount.

Solve for K
K-4a= -1
Answer:
I love algebra anyways
The ans is in the picture with the steps how i got it
(hope this helps can i plz have brainlist :D hehe)
Step-by-step explanation:
The value of K is given by the expression 4a - 1.
To solve for K in the equation K - 4a = -1, we want to isolate the variable K on one side of the equation. Here's the step-by-step process:
Start with the equation: K - 4a = -1.
To isolate K, we need to move the -4a term to the other side of the equation. We can do this by adding 4a to both sides of the equation:
K - 4a + 4a = -1 + 4a.
This simplifies to:
K = 4a - 1.
Therefore, the value of K is given by the expression 4a - 1.
