At a football game 3 out of the first 5 students that arrived were wearing a jacket.
Based on this information, if 300 students attend the game, how many students
could be expected to NOT be wearing a jacket?
Answer:
120 students
Step-by-step explanation:
300 / 5 = 60
60 times 3 = 180
300 - 180 = 120 students
120 students could be expected to NOT be wearing a jacket.
What is Unitary method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
for example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
total attendee= 300
if 3 out of the first 5 students that arrived were wearing a jacket
Then, the possibility wearing a jacket
=300 / 5
= 60
and, 60 times 3 = 180 wearing a jacket
Now, students could be expected to NOT be wearing a jacket
=300 - 180
= 120 students

Step-by-step explanation:
The number of daily sales of a product was found to be given by S = 600xe−x2 + 600 x days after the start of an advertising campaign for this product. (Round your answers to one decimal place.) (a) Find the average daily sales during the first 30 days of the campaign—that is, from x = 0 to x = 30. (b) If no new advertising campaign is begun, what is the average number of sales per day for the next 20 days (from x = 30 to x = 50)?
Answer:
a. 20520
b. 12600
Step-by-step explanation:
Given the function S = 600xe^-x² + 600.
a. To find the average, we have to find the definite integral of the function because average, as it is known, is the sum of data points divided by the size of its dataset, this can be used for discrete data. Integral formula is just the continuous form of average, so we are using integral because we were given an interval of x= 0 to X = 30.
Let's integrate 100xe^x² first. Let –x² = u, this means –2xdx = du and we have dx = –du/2x. Also, when x = 0, u = –(0)² = –0 and when x = 30, u = –(30)² = –900. When we make our substitutions we have:
–600(xe^udu)/2x = –600(e^udu)/2 upon integrating that we have –600(e^u)/2. Applying our interval we have
–600[(e^900)/2 – (e^0)/2] ≈ – [– 3.7 – (1/2)] = –600 (–4.2) = 600 x 4.2 = 2520
Now let's integrate 600, with the interval x = 0 to x = 30 (we are using this interval here because the substitution we made didn't affect this).
We have, upon integrating:
600x.
Substituting our intervals we have:
600(30 – 0) = 600 x 30 = 18000.
Adding that up we have: 2520 + 18000 = 20520.
b. The same method is needed, just difference of interval.
Therefore, after integrating the first component with intervals u = 900 to u = 2500 (from x² = u) we have:
–600[(e^2500)/2 – (e^900)/2] ≈ –600[2.7 – 3.7] = –600(–1) = 600.
Then for the second component:
600x using x = 30 to x = 50
600(50 – 30) = 600 x 20 = 12000.
Adding that up we have:
12000 + 600 = 12600.

Triangle XYZ is a scale drawing of triangle ABC.
Triangle ABC has side lengths 3, 4, & 5.
Triangle XYZ has corresponding side lengths x, 12, & 15.
What is the value of x?
Answer:
x = 9
Step-by-step explanation:
∆ABC is similar to ∆XYZ
Therefore:
[tex] \frac{AB}{XY} = \frac{BC}{YZ} [/tex]
AB = 4
XY = 12
BC = 3
YZ = x
Plug in the values
[tex] \frac{4}{12} = \frac{3}{x} [/tex]
Cross multiply
4x = 36
Divide both sides by 4
x = 9
Solve system of equation by elimination:
4x - y = 1
3x + y = -1

Mrs. Miller has only $42.50 to spend at walmart. She buys a shirt that costs $29, including tax. She wants to buy some bracelets for 4.50 each, including tax. Write an equation to determine x, the maximum number of bracelets Mrs. Miller can buy
Answer: 2
Step-by-step explanation: 42.50 is the max she can spend there’s .08 cent per dollar. $29 dollars for the shirt plus tax it’ll be 31.32 now Mrs.Miller is left with 11.18 out of her 42.50. Divide 11.18 by 4.50 because that’s the cost of each bracelet. 4.50 multiplied by 2 equals 9 plus tax it’ll be 9.72. 11.18 she had left minuse the 9.72 she’s left with 1.46

How many solutions are there to the equation below?
4x-9(x+ 1) = 20- 5x
OA. 1
O B. 0
OC. Infinitely many
Answer:
no solution
Step-by-step explanation:
heres why:
Let's solve your equation step-by-step.
4x−9(x+1)=20−5x
Step 1: Simplify both sides of the equation.
4x−9(x+1)=20−5x
4x+(−9)(x)+(−9)(1)=20+−5x(Distribute)
4x+−9x+−9=20+−5x
(4x+−9x)+(−9)=−5x+20(Combine Like Terms)
−5x+−9=−5x+20
−5x−9=−5x+20
Step 2: Add 5x to both sides.
−5x−9+5x=−5x+20+5x
−9=20
Step 3: Add 9 to both sides.
−9+9=20+9
0=29
so there are no solution

The answer since none of the others are correct are 0,5, and 8. Otherwise known as B,C,and D
Answer:
8, 5, 0 (B, C, D)
Step-by-step explanation:
okay so in order to solve this, first you would do 300-140 since the limit is 300 and 140 is already occupied. 300-140=160. Next, to find the number of 20-pound bags that can fit, you would do 160/20 or just 20b<_160 (<_ is less than or equal to). b<_ 8, therefore you could have anything ranging from 0b-8b. You cannot have a negative number of bags, that is just not possible, and with 10 bags, you surpass the weight limit by 40 pounds.

Answer:
25 = 50%
37.50 = 75%
75 = 150%
Step-by-step explanation:
We know that 50 is 100% so we can work with that.
We also know the percentages increase by 25% for every $12.5.
12.50 + 12.50 = 25
25 + 12.50 = 37.50
62.50 + 12.50 = 75
25 = 50%
37.50 = 75%
75 = 150%
