On Thursday the basketball coach ordered 12 pizzas for 36 players who came in for practice. How many pizzas does the coach need to order if 12 players turned up for practice the next day
Answer:16
Step-by-step explanation:Next day there will be (36+12) or 48 players.
For 36 players 12 pizzas are needed
For 1 player 12/36 pizzas are needed
For 48 players 12/36*48 or 16 pizzas are needed
The number of pizzas that 12 players will need is 4 based on the given ratio.
What are the ratio and proportion?The ratio is the division of the two numbers.
Proportion is the relation of a variable with another. It could be direct or inverse.
As per the given,
The ratio of pizza to players = 36/12
With the same ratio,
The number of pizzas required for x number of 12 players,
12/x = 36/12
x = 144/36 = 4
Hence "Based on the above ratio, 12 players will require 4 pizzas.".

Answer:
5(x)+2(y)=3.45
7(x)+3(y)=4.90
The system of equation are
5x+ 2y = 3.457x+ 3y= 4.90what is Algebra?A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them. Variables are the name given to these symbols because they lack set values. We frequently observe constant change in specific values in our day-to-day situations. But the need to depict these shifting values is ongoing. These values are frequently represented in algebra by symbols such as x, y, z, p, or q, and these symbols are known as variables. In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.
Given:
On Monday 5 apples and 2 oranges for a total of $3.45.
On Thursday she bought 7 apples and 3 oranges for a total of $4.90.
let the number of apples sold be x
and, let the oranges sold be y

At a football stadium, 5% of the fans in attendance were teenagers. If there were 10 teenagers at the football stadium, what was the total number of people at the stadium?
Answer:
200 people were at the stadium
Step-by-step explanation:
Let us represent the total number of people at the stadium = x
At a football stadium, 5% of the fans in attendance were teenagers. If there were 10 teenagers at the football stadium
Hence:
5% of total number of people = 10 teenagers
5/100 × x = 10
5x/100 = 10
Cross Multiply
5x = 100 × 10
5x = 1000
Divide both sides by 5
5x/5 = 1000/5
x = 200
The total number of people in the stadium is 200
) 10 counters in a bag. 4 red, 3 green, 2 pink and 1 blue. Ella picks a counter at random from the bag, notes the colour and then puts it back in the bag. a) Ella uses this method to work out the probability of selecting 2 greens in a row. She writes: "There are four colours, so the probability of selecting a green is 1 4 + 1 4 = 2 4 , so the probability is 1 2 ." a) Make two criticisms of Ella's method. b) Calculate the probability of selecting two counters of the same colour. (
Answer:
a) i) The probability depends on the total number of counters not on the number of colors.
ii) There are 10 number of counters not 4
b) [tex]\dfrac{3}{10}[/tex]
Step-by-step explanation:
Given that:
Total number of counters in a bag = 10
Number of red counters = 4
Number of green counters = 3
Number of pink counters = 2
Number of blue counters = 1
a) Ella writes: "There are four colors, so the probability of selecting a green is [tex]\frac{1}4 + \frac{1}4 = \frac{2}4[/tex] , so the probability is [tex]\frac{1}2[/tex]"
Ella has considered the total type of counters here, which is 4.
But Ella must have considered total number of counters which is 10.
i) The probability depends on the total number of counters not on the number of colors.
ii) There are 10 number of counters not 4
b) There are 4 colors in the bag.
Formula for probability of an event E can be observed as:
[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text {Total number of cases}}[/tex]
To select 2 counters of the same color:
[tex]P(2\ red) = \dfrac{4}{10}\times \dfrac{4}{10} = \dfrac{16}{100}[/tex]
[tex]P(2\ green) = \dfrac{3}{10}\times \dfrac{3}{10} = \dfrac{9}{100}[/tex]
[tex]P(2\ pink) = \dfrac{2}{10}\times \dfrac{2}{10} = \dfrac{4}{100}[/tex]
[tex]P(2\ blue) = \dfrac{1}{10}\times \dfrac{1}{10} = \dfrac{1}{100}[/tex]
The required probability will be the sum of all 4 above probabilities:
[tex]P(2\ of\ same\ color) = \dfrac{30}{100} = \bold{\dfrac{3}{10} }[/tex]

Felipe sold t-shirts and hats at a festival. He made a $5 profit for each t-shirt he sold. He also made a profit of $40 from selling hats. If he made a total profit of $125, how many t-shirts did he sell?
Answer:
17 t-shirts sold
Step-by-step explanation:
If we assume that we don't need t find the number of hats, then we can say that the profit from -tshirts would be $125 minus 40 or $85
Then we can write the following equation of x is the number of t-shirts:
5x = 85
If we solve by diving both sides of the equation by 5:
5x/5 = 85/5
x = 17 t-shirts sold

Isadora rents an apartment for $1,000 a month and has a year's lease.
She owns a car that is worth $14,700. She has a savings account of $4,750 and a
credit card balance of $825. What is her net worth?
Step-by-step explanation:
So let's say this is for the year and were working out the amount she spent.
She starts off with paying $1,000 for rent.
Then she owns a car that is $14,700.
Her savings account is 4,750 and Credit card balance is 825{not sure if that's what she is has to spend or if its tax so I'll do two ways}.
1,000
4,750
825
+14,700
21325
Her total would be $21,325 taking it that 875 was a tax.
if not the answer would be $20,450.
if the car does not have a tax just minus the 14,700 from either of them two numbers.
Amount of Isadora's net worth is $6,625.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
To find Isadora's net worth, we need to subtract her total debts from her total assets.
So,
Her total assets.
Car worth = $14,700
Savings account balance = $4,750
So, her total assets.
= $14,700 + $4,750
= $19,450
Her total debts.
Credit card balance = $825
Monthly rent for 1-year lease = $1,000 x 12 = $12,000
So, her total debts.
= $825 + $12,000
= $12,825
To find her net worth, we subtract her total debts from her total assets.
So,
Net worth = Total assets - Total debts
Net worth = $19,450 - $12,825
Net worth = $6,625
Therefore,
Isadora's net worth is $6,625.

9+3.5g=11−0.5g i need this anwser plz help
Answer:
g = 1/2
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDASEquality PropertiesStep-by-step explanation:
Step 1: Define equation
9 + 3.5g = 11 - 0.5g
Step 2: Solve for g
Add 0.5g on both sides: 9 + 4g = 11Subtract 9 on both sides: 4g = 2Divide 4 on both sides: g = 1/2Step 3: Check
Plug in g into the original equation to verify it's a solution.
Substitute in g: 9 + 3.5(1/2) = 11 - 0.5(1/2)Multiply: 9 + 1.75 = 11 - 0.25Add/Subtract: 10.75 = 10.75Here we see that 10.75 does indeed equal 10.75.
∴ g = 1/2 is a solution of the equation.
Answer: g= 0.5
Step-by-step explanation:
Add
3.5g and 0.5g. to get
9+4g=11
then subtract 9 from the 11 and you should get 4g=2.
then divide 4 from 2 and you should get the answer of 2/4.
simplify it and you should get the answer g=0.5

Stephanie grew a total of 70 pounds of tomatoes to sell. She plans to sell the tomatoes for $3.50 per pound. The equation below represents the profit in dollars, f(x), she will earn by selling x pounds of the tomatoes.
f(x) = 3.50x - 110
If Stephanie sold all 70 pounds of tomatoes, what would her profit be?
Answer:
If Stephanie sold the 70 pounds of tomatoes, her profit would be 135 dollars.
Step-by-step explanation:
You know that the equation f(x) = 3.50*x - 110 represents the profit in dollars Stephanie will earn by selling x pounds of the tomatoes.
If Stephanie sold the 70 pounds of tomatoes, you want to know what the profit would be. So to calculate the profit you simply replace in f (x), the x pounds of tomatoes by 70.
f(70)=3.50*70 - 110
Solving:
f(70)= 245 - 110
f(70)= 135
If Stephanie sold the 70 pounds of tomatoes, her profit would be 135 dollars.
