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

Again, plz help I’m desperate
Answer:
4/3 (answer choice b)
Step-by-step explanation:
first, you convert the equation to slope intercept form as well as make sure y doesn't have a coefficient by dividing the whole equation by 4. (y=-3/4x+6) Next, you find the reciprocal of the slope which in this case is -4/3 ,and divide it by -1 giving you 4/3.

What is the rule to change a percent to a decimal?
Answer:
Move the decimal point two places to the left
Step-by-step explanation:
Answer:
To change a percent to a decimal we divide by 100. This is the same as moving the decimal point two places to the left. For example, 15% is equivalent to the decimal 0.15.

Riley earned $5 for 1 2 of an hour babysitting. What is her hourly rate? Simplify your answer and write it as a proper fraction, mixed number, or whole number.
Answer:
Riley's hourly rate is $10
Step-by-step explanation:
Riley earned $5 for 1/2 of an hour babysitting. What is her hourly rate?
1/2 of an hour = $5
1 hour = $x
Cross Multiply
1/2 × x = $5 × 1
x = $5 ÷ 1/2
x = $5 × 2
x = $10
Hence, Riley's hourly rate is $10

Step-by-step explanation:
Mr. Lee is a hotdog and drink vendor at a baseball game. Hot dogs are 3.50 and drinks are 1.50. If Mr. Lee sold enough to make 450 dollars on Monday. He remembers that on Monday he sold three times as many drinks as he did hot dogs. How many hot dogs and how many drinks did Mr. Lee sell on Monday?
Answer:
33 hotdogs and 225 drinks on Monday
Step-by-step explanation:
We would use the ratio of 1:3 hotdogs to drinks
Split the ratio in 450 and we get 112.5:337.5
$112.5 would be the earnings of hotdogs
$337.5 would be the earnings of the drinks
Now we divide each individually by its cost
$112.5/3.5
= 32 1/7,
$337.5/1.5
= 225
We will round the hotdogs to 33 as the word problem says "sold enough to make."

The sum of 9/26 and -4/13
Answer:
Step-by-step explanation:
Ok, well the first thing you need to do is make -4/13 have the same numerator as 9/26. Thankfully, 26 is a multiple of 13, so that step is easy:
-4/13 -> -8/26
Then you can add them together with ease.
9/26 + -8/26 = 1/26
Adding a negative number to anything is the same thing as subtracting.
A box of cereal states that there are 90 calories in a 3 4-cup serving. What is the unit rate for calories per cup? How many calories are there in 2 cups of the cereal?
Answer:
Calories per cup = 120 calories
Calories in 2 cups = 240 calories
Step-by-step explanation:
Given that:
Number of calories in a [tex]\frac{3}{4}^{th}[/tex] cup serving = 90 calories
To find:
Unit rate for calories per cup = ?
Number of calories in 2 cups of cereal = ?
Solution:
Here we are given the number of calories in a [tex]\frac{3}{4}^{th}[/tex] cup serving.
To find the calories in one cup, we need to divide 90 calories with [tex]\frac{3}{4}[/tex].
So, unit rate for calories per cup can be given as:
[tex]\dfrac{90}{\frac{3}4}\\\Rightarrow \dfrac{90}{3}\times 4\\\Rightarrow \bold{120 \ calories}[/tex]
To find the calories in 2 cups of cereal, we need to multiply the unit rate for calories per cup with 2.
So, calories in 2 cups of cereal = [tex]120 \times 2[/tex] = 240 calories
Therefore, the answer is:
Calories per cup = 120 calories
Calories in 2 cups = 240 calories

The height in feet, h, of a base jumper Is jumping off a cliff is given by the equation
h = 3t^2 - 700t + 2000,
where t is the time is seconds. How long will it take the jumper to reach the ground?
Answer:
233 seconds
Step-by-step explanation:
When h = 0 the jumper ends his/her jump. Therefore let h = 0 so that we can solve for t; forming a quadratic equation
0 = 3t^2 - 700t + 200
I am going to solve using the quadratic formula, but there are other approaches--
[tex]t_{1,\:2}=\frac{-\left(-700\right)\pm \sqrt{\left(-700\right)^2-4\cdot \:3\cdot \:200}}{2\cdot \:3},\\\\\sqrt{\left(-700\right)^2-4\cdot \:3\cdot \:200} = 20\sqrt{1219},\\\\t_{1,\:2}=\frac{-\left(-700\right)\pm \:20\sqrt{1219}}{2\cdot \:3}[/tex]
[tex]\:t_2=\frac{-\left(-700\right)-20\sqrt{1219}}{2\cdot \:3}[/tex]
[tex]t=\frac{10\left(35+\sqrt{1219}\right)}{3},\:t=\frac{10\left(35-\sqrt{1219}\right)}{3}[/tex]
Now the solutions are around 233 and 0.3 seconds. Given these two solutions I would find the first one more predictable.

Twice as many students are in the chess club as in the fencing club.The number of students in the fencing club is one fifth the number of students in the cooking club.There are 42 more students in the cooking club than in the chess club.How many students are in the chess club?
Answer:
28 students
Step-by-step explanation:
Let number of students in cooking club = x
Number of students in fencing club = 1/5 x
Number of students in chess club = 2(1/5)x
Since, There are 42 more students in the cooking club than in the chess club
Then ;
Number of students in chess club = Number of students in cooking club - 42
2(1/5)x = x - 42
(2/5)x - x = - 42
(2/5)x - x = - 42
-0.6x = - 42
x = 42 / 0.6
x = 70
Hence, number of students in chess club :
(2/5) * 70 = 28
