Staci is attending a music festival. The ticket to the festival costs $87.96 . Staci plans to purchase $30.00 t-shirts form the event for close friends. She is taking $200.00 to the festival . What is the maximum Numbers of t-shirts staci can purchase
Answer:
3 t-shirts
Step-by-step explanation:
Lets recap the information we will use from this problem:
The ticket to the festival costs $87.96
T-shirts are $30.00
She is taking $200.00 to the festival
Now we can solve. First we will subtract the price of the ticket from the total amount of money she has.
$200.00 - $87.96 = $112.04
Now that she has payed for the ticket, we want to find out how many shirts she can buy with the remainder of her money. To find this, we will set up an equation like this:
(Amount of money left) ÷ (Cost of 1 t-shirt) = (How many t-shirts she can buy)
Insert your numbers: $112.04 ÷ $30.00 = 3.73466666667
Because she cant buy a fraction of a t-shirt, we ignore the decimals on the end of this number. Therefore, Staci can purchase 3 t-shirts.
After paying for the festival ticket, Staci will have $112.04 left. As each t-shirt costs $30, she can buy a maximum of 3 t-shirts.
Explanation:The question is about determining how many T-shirts Staci can purchase given a specific budget. First, Staci has to cover the cost of the music festival ticket, which is $87.96. After paying for the ticket, Staci would have $200 - $87.96 = $112.04 left.
Given that each T-shirt costs $30, the maximum number of T-shirts she can purchase can be calculated by dividing the remaining amount by the cost of a T-shirt. Hence, $112.04/$30 ≈ 3.73. Since she can't buy a fractional T-shirt, the maximum number of T-shirts she can buy is 3.

you have 480 roses and 24 of them dies, how many per cent died?
Answer:
5%
Step-by-step explanation:
5% of the roses died.
480 roses = Total number of roses
24 roses = number of roses that died
24 roses that died as a percent of 480 the total is:
24/480*100= 5%
To find the percent of roses that died, we take the number of roses that died and divide it by the total amount of roses there are and multiply it by 100 to find the percent.
Final answer:
To find out the percentage of roses that died, you can use a proportion where 24 out of 480 roses is equal to x out of 100, and solve for x, resulting in 5% of the roses that died.
Explanation:
To calculate the percentage of roses that died, you can set up an equivalent fraction that compares the number of dead roses to the total number of roses, with 100 as the denominator. In this case, 24 roses died out of 480. The fraction for this scenario is 24/480, and you want to find out how this fraction translates to a percentage.
To do this, you would set up a proportion like this:
24/480 = x/100
Cross-multiply to solve for x, which represents the percentage of dead roses:
24*100 = 480*x
2400 = 480*x
x = 2400/480
x = 5
So, 5% of the roses died.
Find the minimum value of
C = x + y
subject to the following constraints:
2x + y = 20
2x + 3y = 36
X=0
Y=0
Answer:
14
Step-by-step explanation:
2x + y = 20 (1)
2x + 3y = 36 (2)
(2) - (1) ⇔ (2x - 3y) - (2x + y) = 36 - 20
⇔ 2y = 16
⇔ y = 8 (3)
From (3) and (1), we have:
2x + y = 2x + 8 = 20
⇔ 2x = 12
⇔ x = 6
So: C = x + y = 6 + 8 = 14
Conclusion : C = 14
Brainliest, please?
The minimum value of the function C = x + y, under the given constraints, is 0. This is obtained when both x and y are equal to 0. If the constraints 2x + y = 20 and 2x + 3y = 36 are considered, the value obtained is 16, which is larger.
Explanation:To solve this problem, we need to substitute the values of x and y into the function C = x + y and then find the minimum. As our initial constraints state x=0 and y=0, we can try these values first. C at (x = 0, y = 0) is 0 + 0 = 0.
The above scenario considers only the initial constraints x=0 and y=0.So, let's consider the constraints 2x + y = 20 and 2x + 3y = 36. We can solve these two equations simultaneously to get the values of x and y. When we solve them, it results x = 4 and y = 12. Substitute these values in the function C = x + y, we get C = 4 + 12 = 16.
Therefore, comparing the values obtained, the minimum value of the function C = x + y, subjected to the given constraints, is 0 when both x and y are 0.

Danesh is incorrect as the multiplication of 1.496 × 1011 and 6.68 × 109 results in a value with 1020, not 1099. Moreover, 1 googol equals 1 × 10100, which is much larger.
Explanation:No, Danesh is incorrect. According to the laws of exponents, when you multiply two powers with the same base, you add the exponents. Therefore, the multiplication of 1.496 × 1011 and 6.68 × 109 will result in a value that is multiplied by 1020 and not 1099. Also, 1 googol is significantly larger than the result of this multiplication because it is equal to 1 × 10100. Thus, the statement made by Danesh is inaccurate.

The original price of the shorts is $35. They are on sale for 25% off. What is the sale price?
Answer:
$26.25
Step-by-step explanation:
So what you do is divide 25 by 100 so its a decimal .25 then multiply that by 35 and you get 35/4 or 8.75 you take that number and subtract it from 35 and you get 26.25.
For future reference what ever percentage you have like if says it went up 80% you divide that by a hundred also and you get .80 you multiply that by 35 you get 28 you don't subtract it from the original price but you add it so you get 35+28=63 and that's your final answer.
Remember you divide the percentage for example 25 by 100 multiply by the price it gives for example 35 if the question says off you subtract what you got from the original price if it went up you add it to the original price and that's your final answer. Hope this help :)

Part B) The graph in the attached figure
Part C) see the explanation
Step-by-step explanation:
Part A) Write a system of inequalities that can be used to represent the situation.
Let
x ----> the number of hours worked as a babysitter
y ----> the number of hours worked as a library assistant
we know that
She is able to work no more than 15 hours a week
so
[tex]x+y\leq 15[/tex] -----> inequality A
Edith wants to earn at least $80 a week
The word "at least" means " greater than or equal to"
so
[tex]4x+8y\geq 80[/tex] ----> inequality B
Part B) Graph these inequalities on the set of axes.
Using a graphing tool
The solution of the system is the triangular shaded area in the attached figure
Part C) Determine and state one combination of hours that will allow Edith to earn at least $80 per week while working no more than 15 hours
we know that
If a ordered pair is a solution of the system of inequalities, then the ordered pair must satisfy both inequalities. (The ordered pair lie in the shaded area of the solution set)
Looking at the graph
The ordered pair (4,9) lie in the shaded area
Verify if the ordered pair satisfy both inequalities
Inequality A
[tex]4+9\leq 15[/tex]
[tex]13\leq 15[/tex] ---> is true
so
The ordered pair satisfy the inequality A
Inequality B
[tex]4(4)+8(9)\geq 80[/tex]
[tex]88\geq 80[/tex] --> is true
so
The ordered pair satisfy the inequality B
therefore
The ordered pair is a solution of the system
(4,9)
That means
The number of hours worked as a babysitter in a week is 4 and the number of hours worked as a library assistant in a week is 9
Edith can babysit for 5 hours and then work for 10 hours as the library assistant in a week so as to earn at least $80 a week
InequalityAn inequality is an expression that shows the non equal comparison of two or more numbers and variables.
Let x represent the number of hours at the $4 job and y represent the number of hours at the $8 job, hence:
x + y ≤ 15 (1)

PLEASE HELP ASAP
A: The absolute value of a number gives its distance from zero on the number line.
B: when you multiply either number by -1, you get the other.
C: The absolute value of a number always gives the opposite of a negative number in the square of a positive number.
D: when the numbers are squared, they give the same answer.
Answer:
The answer A. "The absolute value of a number gives its distance from zero on the number line."
Step-by-step explanation:
An absolute number has these in it '| |'. An absolute number always is positive, because it represents a difference.
For example, the difference of 0 and -30 is |30|.
Though 0 - 30 is -30, the DIFFERENCE is |30|.
As the answer says, "its distance from zero on the number line".
Final answer:
The absolute value of -9 equals the absolute value of 9, which is 9, because absolute value represents the distance from zero on the number line, and both -9 and 9 are 9 units away from zero, regardless of their direction.
Explanation:
The reason why |-9| = |9| is because the absolute value of a number refers to its distance from zero on the number line. This distance is always a non-negative number since it does not refer to direction, just the magnitude of separation from zero. Therefore, both -9 and 9 are 9 units away from zero, and their absolute values are equal.
In mathematical terms, the absolute value function, denoted by | |, strips away the sign of a number, turning any negative number into its positive counterpart. So, |9| is already positive, and |-9| transforms -9 into 9 because you remove the negative sign, rendering both absolute values equivalent.
