You have an allowance of $12.00. You buy a discount movies ticket that costs at least $3.50 and popcorn that costs $2.75. HOw much do much do you have for other spending?
Given
You have an allowance of $12.00
discount movies ticket that costs at least $3.50
popcorn that costs $2.75.
Find out the how much do much do you have for other spending.
To proof
Let us assume that the money for the other spending be x.
As given
total allowance = $12.00
discount movies ticket that costs at least = $3.50
popcorn costs = $2.75
than the inequality written in the form
3.50 + 2.75 + x ≤ 12.00
6.25 + x ≤ 12.00
x ≤ 5.75
you have money for other spending is atmost 5.75
when the movies ticket that costs at least $3.50
Hence proved
Final answer:
After purchasing a discounted movie ticket for at least $3.50 and popcorn for $2.75 from an allowance of $12.00, the student will be left with $5.75 for other spending.
Explanation:
The student is given a scenario involving budgeting and calculating remaining allowance after certain purchases. To find out how much money is left for other spending after purchasing a discounted movie ticket and popcorn, we subtract the total cost of these items from the initial allowance.
If the student has an allowance of $12.00 and buys a movie ticket for at least $3.50 and popcorn for $2.75, the calculation for the remaining allowance will be as follows:
Minimum amount spent on movie ticket: $3.50Amount spent on popcorn: $2.75We add these two amounts to find the total spent:
Total spent = $3.50 + $2.75 = $6.25
We then subtract the total spent from the initial allowance:
Remaining allowance = $12.00 - $6.25 = $5.75
Therefore, the student will have $5.75 left for other spending.
Carson evaluated 23÷34 and got an answer of 89. Which statement is true about his answer?

It is correct because 8/9x3/4=2/3
Step-by-step explanation:
Nuclear power provided 78% of the energy used in france in 2005. Write 0.78 as a fraction in simplest form.
Here we are given first that Nuclear power provided 78% of the energy used in france in 2005.
Now this was written in decimal as 0.78.
Then we have to write it in fraction form.
So first we have here two digits after the decimal, so in denominator we will have 100,
[tex]\frac{78}{100}[/tex]
Now we have to convert this into simplest form.
For that we have to find HCF of 78 and 100.
The HCF of 78 and 100 is 2, so we will divide both numerator and denominator by 2,
[tex]\frac{78/2}{100/2}[/tex]
This gives us:
[tex]\frac{39}{50}[/tex]
Answer: The simplest form of 0.78 as as fraction is 39/50.

Which statement is true about polynomial 5s^6t^2 + 6st^9 - 8s^6t^2 - 6t^7 after it has been fully simplified?
The polynomial 55° + 6st - 85° - 6t has 4 terms and a degree of 10 after it has been fully simplified.
To determine the number of terms in a polynomial, count the separate algebraic expressions that are added or subtracted. In this case, the polynomial is composed of four distinct terms: 55°, 6st, -85°, and -6t.
Next, the degree of a term in a polynomial is the highest power of its variable. Examine each term to identify the variable and its corresponding exponent. The term 55° has a degree of 0 since any nonzero constant raised to the power of 0 is 1. Both 6st and -6t have a degree of 2, as the variables s and t are raised to the power of 1. Lastly, the term -85° has a degree of 1.
To find the overall degree of the polynomial, identify the term with the highest degree. In this case, it is the term 6st, which has a degree of 2. Therefore, the fully simplified polynomial has four terms and a degree of 2, making the correct statement: "It has 4 terms and a degree of 10."

the table describes the types of job openings available in a company. what is the probability that experience is needed for a randomly selected job opening, given that it is for part time work?
Answer:
42%
Step-by-step explanation:
We will use the conditional probability in this case
We use conditional probability when two cases occur are dependent.
So by using:
[tex]\frac{P(A\capB)}{P(B)}[/tex]
Here, A is the event of experience needed.
And B is the event of part-time
Substituting the values in the formula we get:
[tex]\frac{6}{14}=.42[/tex]
Intersection of experience needed and part-time is 6
And part-time total is 6+8=14
To get in percent we will multiply it by 100
42% is the required probability.

:) hope this helps!
The domain of the function H(t), which models the height of a plant over time, would consist of integers ranging from -2 to 98 to represent each day of the plant's growth, including the two days before purchase.
Explanation:The question at hand is asking which type of number is more appropriate for the domain of a function, H(t), that models the height of Pooja's plant (in centimeters) t days after she bought it. The domain of a function includes all the possible inputs for the function, in this case, the number of days after Pooja bought the plant. Considering Pooja's plant sprouted 2 days before she bought it and lasted for 98 days, the best number type for the domain would be integers since the days are counted in whole numbers. However, if we include the 2 days before she bought it, the domain in context would be from -2 to 98. Therefore the domain would be {-2, -1, 0, 1, 2, ..., 98}, which are all integers.

Which two square roots are used to estimate√8?
A. √2 and √3
B. √3 and √4
C. √4 and √9
D. √9 and √16
Which two square roots are used to estimate √42
A. √25 and √36
B. √36 and √49
C. √49 and √64
D. √25 and √64
Answer:
Option C.
Option B.
Step-by-step explanation:
By definition, the square of a number is that number times itself.
The square root of a perfect square is a whole number.
Since the square root of another number (not perfect square) is not a whole number, you can estimate it finding two perfect square roots that number is between.
1) Observe that 4 and 9 are perfect squares:
[tex]4=2^2\\9=3^2[/tex]
And 8 is between those numbers.
Therefore, the square roots [tex]\sqrt{4}[/tex] and [tex]\sqrt{9}[/tex] are used to estimage [tex]\sqrt{8}[/tex]
2) Notice 36 and 49 are perfect squares:
[tex]36=6^2\\49=7^2[/tex]
And 42 is between those numbers.
Therefore, the square roots [tex]\sqrt{36}[/tex] and [tex]\sqrt{49}[/tex] are used to estimage [tex]\sqrt{42}[/tex]
The square roots used to estimate √8 are √4 and √9 while the square roots to estimate √42 are √36 and √49.
Explanation:The two square roots that are used to estimate √8 are √4 and √9 since the value of √8 falls between the value of these two square roots (2 and 3). The reason why these are chosen is due to √8 being greater than √4 and less than √9. Similarly, the two square roots to estimate √42 are √36 and √49. The square root of 42 is more than the square root of 36 (which is 6) and less than the square root of 49 (which is 7). Therefore, to estimate the square roots, we find two perfect squares that the number falls between.

the perez family has a rectangle fish tank. How much water will the tank hold if its length is 3 feet, its width is 2 feet, and its high is 3 feet
Hello there
Since there is 1 foot water in the tank the total volume = 3*2 * 1
= 6 cubic feet.
volume of 6 cu. feet corresponds to 1 foot of water in height, this will help you find your answer
The Perez family's rectangular fish tank can hold 18 cubic feet of water by multiplying the length, width, and height (3ft x 2ft x 3ft).
To calculate the amount of water the Perez family's rectangular fish tank can hold, we use the formula for the volume of a rectangle, which is length * width * height.
Given:
Length (l) = 3 feetWidth (w) = 2 feetHeight (h) = 3 feetThe volume (V) is calculated as:
V = l * w * h
V = 3 feet * 2 feet * 3 feet
V = 18 cubic feet
Therefore, the rectangular fish tank can hold 18 cubic feet of water.

One angle = a
So,
Another angle = a - 50
So,
a + (a - 50) = 180
2a - 50 = 180
2a = 230
a = 115°
another angle = 180 - 115
