a school has 294 chairs.there are 14 chairs at each table. two chairs will be removed from each table.how many chairs will be left in the cafeteria?
Answer:
252
Step-by-step explanation:
because there are 14 chairs at each table => there are: 294/14= 21 (tables)
two chairs will be removed from each table => the number of chairs removed are: 21.2 = 42 (chairs)
the chairs will be left in the cafeteria are: 294 - 42 = 252( chairs)
When two chairs will be removed from each table, then there would be 252 chairs left in the cafeteria.
The dividend divisor quotient remainder formula:Dividend = Divisor × Quotient + Remainder.
For given question,
total number of chairs = 294
there are 14 chairs at each table.
So, to find the number of tables in the cafeteria we need to divide total number chairs by 14.
The number of table would be,
= 294/14
= 21
This means, there are 21 tables.
If we remove two chairs from each table, then number of chairs at each table would be 14 - 2 = 12
So, the total number of chairs left in the cafeteria would be,
= 21 × 12
= 252
Hence, there will be 252 chairs left in the cafeteria.

12. The second of three numbers is one less than the first. The third
number is 5 less than twice the second. If the third number exceeds the
first number by 12, find the three
numbers.
Answer:
The three numbers are 19, 18, and 31.
Step-by-step explanation:
The three numbers are x, y, and z.
y=x-1
z=2y-5
z=x+12
2y-5=x+12
2(x-1)-5=x+12
2x-2-5=x+12
x=19
y=18
z=31
The three numbers are 19, 18 and 31
what is Algebra?Algebra is the branch of mathematics that helps in the representation of problems or situations in the form of mathematical expressions.
let the three numbers be x, y, and z.
So, according to question
The second of three numbers is one less than the first,
y = x-1
The third number is 5 less than twice the second,
z=2y-5
also, If the third number exceeds the first number by
12z=x+12
Now, equating the equations
2y-5=x+12
2(x-1)-5=x+12
2x-2-5=x+12
x=19
So, y=18 and z=31.

1. A local pizzeria sold 65 pizzas yesterday.
(step 1) The owner offers the employees a bonus if the number of pizzas sold increases by 20% today. How many pizzas must the pizzeria sell for employees to receive the bonus? Explain your reasoning.
(Part 2) Suppose the actual number of pizzas sold today was 60. Describe the number of pizzas sold as a percent increase or decrease, rounded to the nearest hundredth. Show your work.
Answer:
Part 1
Pizzas sold last day = 65
Increasement needed in sale = 20%
pIzzas to be sold today
= 65 + 20% of 65
= 65 + 20/100 × 65
= 65 + 1/5 × 65
= 65 + 1/1 × 13
= 65 + 13
= 78
Part 2
Pizzas sold last day = 65
Pizzas sold today = 60
60 = 65 + x% of 65
60 = 65 + x/100 × 65
60 - 65 = x/20 × 13
- 5 = x/20 × 13
-5/13 = x/20
-5/13 × 20 = x
-7.692 = x
Therefore, there was a decrease in pizza sale by 7.692%
By rounding off,
The decrease in pizza sale was by 7.700%.
= 7.7%

What is a line? Why might the graph of a function be represented
by a line?
Definition:
A line is a one-dimensional figure, characterized by its length but no width (thickness). A line is made of a set of points which is extended in opposite directions infinitely.
A line is determined by two points in a two-dimensional plane such as the x-y plane.
The graph of a function can be represented by a line because all points on the line provide a solution to the function. Such functions are usually linear functions.

Solve for x I need help ASAP!
Let's solve your equation step-by-step.
2x+9=8x+21
Step 1: Subtract 8x from both sides.
2x+9−8x=8x+21−8x
−6x+9=21
Step 2: Subtract 9 from both sides.
−6x+9−9=21−9
−6x=12
Step 3: Divide both sides by -6.
-6x/-6=12/-6
x=-2
Answer:
-2 = x
Step-by-step explanation:
First, combine like-terms. I subtracted 21 from both sides and subtracted 2x from both sides. This gave us 12 = -6x. Then, divide to solve for x. This gives us -2 = x.

Thus the equivalent ratio to 8:5 will be,
24:15 , 40:25 and 16:10
because, here if we reduce by common multiple 24:15 , 40:25 and 16:10 both , we will get as 8:5
so the correct answer is c.) 40:25 and e.) 16:10 b.) 24:15

One inlet pipe can fill an empty pool in 12 hours, and a drain can empty the pool in 16 hours. How long will it take the pipe to fill the pool if the drain is left open?
Answer:
48 hours
Step-by-step explanation:
So one Pipe can fill an empty pool in 12 hours, and a drain can empty the pool in 16 hours.
So let's just say that x is the value for how much the pool was filled, and y is the time taken.
So which means :
X = [tex]\frac{1}{12}y[/tex] - [tex]\frac{1}{16} y[/tex]
[tex]\frac{1}{12}[/tex] represents the volume of the tank being filled up in one hour while [tex]\frac{1}{16}[/tex] represents the volume of the tank being drained in one hour. By subtracting, we get to know the volume of the tank being filled up in one hour.
So, we solve the equation.
To find X, we make the denominator of the two fractions the same.
X = [tex]\frac{1}{12}y[/tex] - [tex]\frac{1}{16} y[/tex]
= [tex]\frac{1(4)}{12(4)}y[/tex] - [tex]\frac{1(3)}{16(3)}y[/tex]
= [tex]\frac{4}{48}y[/tex] - [tex]\frac{3}{48}y[/tex]
Then, we subtract.
[tex]\frac{4}{48}y[/tex] - [tex]\frac{3}{48}y[/tex] = [tex]\frac{1}{48}y[/tex]
[tex]\frac{1}{48}[/tex] is the volume of the pool that is filled in one hour
Finally, we find the time taken for the pipe to fill the pool.
If one hour fills [tex]\frac{1}{48}y[/tex] of the pool, then :
1 = [tex]\frac{1}{48}y[/tex]
y = 48 hours.
So, the time taken for the pipe to fill the pool with the drain left open is 48 hours.
HOPE THIS ANSWER HELPED :)last month kiera ran 22 more miles than bianca did if they ran a combined total of 86 miles how many miles did bianca run
Answer:
54 miles
Step-by-step explanation:
86 - 22= 64. 64÷2= 32. BIANCA RAN 32 MILES. 32 + 22= 54. kiera ran 54 miles
Bianca ran 32 miles last month while Kiera ran 54 miles (22 more) for a combined total of 86 miles.
Let x = miles Bianca ran
x + 22 = miles Kiera ran
combined total of their miles is 86 miles
x + (x + 22) = 86
solving for x
2x + 22 = 86
2x = 86 - 22
2x = 64
x = 64 / 2
x = 32
therefore, Bianca ran for 32 miles.
