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.

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.

The cost of renting Party Palace is $ 120 plus $ 15 per person attending the party. If the total cost of renting Party Palace is $ 480 , how many people attend the party?
Answer:
24 individuals
Step-by-step explanation:
Since we are given the actual costs as well as the final total then we can calculate the total number of people that attended the party by doing the following. We first subtract the fixed cost of $120 by the total cost of the party, and then we divide the remainder by the cost per person, which would give us the number of people who attended (x) ...
($480 - $120) / $15 = x
$360 / $15 = x
24 = x
Finally, we can see that a total number of 24 individuals attended the party

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.

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.

A person enters the room.
The mean age of the 6 people is now 16.
What is the age of the person who entered the room?
Answer:
3 years old
Step-by-step explanation:
( 21 + 24 + 18 + 15 + 15 + x ) / 6 = 16
93 + x = 96
x = 3
The person who entered the room is 3 years old.
Answer:
3 years old
Step-by-step explanation:
x= age of the person who entered the room
The sum of 21,+ 24,+ 18,+ 15,+ 15 = 93
(93+x ) divided into 6 = 16
Multiply both sides by 6
93+x = 96
x=3
93+3= 96
96/6 = 16

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%
