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
The ratio of apples to oranges is 4:3. If there are 16 apples, how many total fruits were there?
Answer:
There are a total of 28 fruits.
Step-by-step explanation:
4 in the ratio is 16. And the unit rate of it is 4. You multiply 3 by 4 which equals 12. 16+12=28.
What is the valur of y in the equation 2(3y - 6) = 0?
Answer:
y=2
Step-by-step explanation:
Distribute the 2 into 3y and -6:
6y-12=0
Move the -12 to the other side by adding both sides by 12:
6y-12+12=0+12
=
6y=12
divide both sides by 6:
y=2

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

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

Suppose x, y, and z are different positive integers such that xy, yz, and zx are all perfect
squares. Must x, y, and z be perfect squares? Why or why not?
Answer: Yes, and the numbers are 4, 36, and 9
Step-by-step explanation:
Yes, because it x=4, y=36, and z=9 then 4 * 36=144, 144=12*12 4*9=36, 36=6*6, and 9*36=324, 324=18*18. As you can see they are all perfect squares and 4, 36, and 9 are all perfect sqaures too.

help math pls geometry
Answer:
The point is (8,2)
Step-by-step explanation:
Is this a square or rectangle or rhombus, etc.? Yes, because all the lines are all parallel.
Are AB and FG are parallel to each other right? Yes, so that means whatever you do to F will happen to G and we can start on A, it goes 6 down, then two to the right.
Since all lines are parallel how many steps we do on A to get F, we have to do to B to get G. So, (8,2).

Given the exponential function f(x) = 16(0.75)x, classify the function as exponential growth or decay and determine the percent rate of growth or decay.
Exponential growth, 75% increase
Exponential decay, 75% decrease
Exponential growth, 25% increase
Exponential decay, 25% decrease
Answer:
So the rate of decay is 0.25, or 25%.
Step-by-step explanation:
The variable r gives the rate of decay in the formula f(x) = P(1 − r)x = 16(1 − 0.25)x.
Answer:
Exponential decay, 75% decrease

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.".

) 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]

A fireman is on the middle step of a ladder. (There are the same number of steps above him as below him.) If he goes down 4 steps, then up 7 steps, and then down 13 steps, he will be on the first step above the ground. How many steps does the ladder have?
Answer:
The ladder has 20 steps
Step-by-step explanation:
10 is the direct middle if you go down 4 that is 6, if you go back up 7 you get 13 and if you go back down 13 and you are on the first step 13-13 is 0, so the ladder has 20 steps.
