Answer:
(A) 9
Step-by-step explanation:
First, change the percentage sign into decimal: 51% = 51/100 = 0.51
Multiply 0.51 with 18
0.51 x 18 = 9.18
Note that it is asking for an estimate, and so round to the nearest whole number.
9.18 rounded to the nearest whole number is 9
(A) 9 is your answer.

[tex]96units^2[/tex]
Step-by-step explanation:
The total surface area of a cube is given by [tex]6l^2[/tex].
The first cube has side length [tex]l=6[/tex] units.
This cube has total surface area, [tex]6(6)^2=216units^2[/tex].
If the second cube is reduced in size by [tex]\frac{2}{3}[/tex], then the corresponding change in area is [tex]\frac{2^2}{3^2}=\frac{4}{9}[/tex].
the total surface area of the new cube is [tex]=\frac{4}{9}\times 216[/tex].

Jack is mowing lawns. He mows lawns at a constant rate of 1/3 acre every 3/4 hour. At this rate, which fraction represents the acres Jack can mow per hour?
Answer:
1/4 acre every 1 hour
Step-by-step explanation:
divide 1/3 with 3/4 to find unit rate
Answer:
[tex]\frac{4}{9}acres/hr[/tex]
Step-by-step explanation:
Givens
The constant rate is 1/3 acre per every 3/4 hour.To find the fraction that represents the constant per hour, we just need to divide both expression, like this
[tex]\frac{1}{3}acre \div \frac{3}{4}hr=\frac{1}{3}\times \frac{4}{3} =\frac{4}{9}acres/hr[/tex]
Therefore, the expression that represents the acres Jack can mow per hour is
[tex]\frac{4}{9}acres/hr[/tex]

15-1.3
[tex]15 - 1.3 = [/tex]
Answer:
13.7
Step-by-step explanation:
Rewrite 15 - 1.3 as 15.0 - 1.3.
Then rewrite this result as
15.0
- 1.3
--------
and subtract as indicated.
First note that 15-1 = 14, and that 15-2= 13. Thus, the correct answer will be between 13 and 14.
Subtract:
15.0
- 1.3
--------
This results in 13.7.
15 - 1.3 simplifies to 13.7 is the numeric result obtained after subtracting 1.3 from 15.
When we simplify the expression 15 - 1.3, we are performing basic arithmetic operations, specifically subtraction.
The step-by-step process is:
1. Write down the expression: 15 - 1.3
2. Perform the subtraction: Subtract 1.3 from 15
15 - 1.3 = 13.7
The result 13.7 is the difference between 15 and 1.3.
Is this True or False ?
Answer:
Option B True
Step-by-step explanation:
we know that
A function relates each element of a set (input) with exactly one element of another set (output)
1) "...each element..." means that every element in X (input) is related to some element in Y (output)
2) "...exactly one..." means that a function is single valued. It will not give back 2 or more results for the same input
therefore
f(x) is a function

Which of the following options have the same value as 25% of 64?
Choose 2 answers:
A) 25 • 64
B) 25/100 • 64
C) .25 • 64
D) 64 divided by 25/100
E) 25 divided by 64/100
Answer:
A) 25 • 64
B) 25/100 • 64
C) .25 • 64
D) 64 divided by 25/100
E) 25 divided by 64/100
B and C i believe
The values that have the same value as 25% of 64 are Options B) 25/100 · 64 and C) .25 · 64, both yielding the correct value of 16 when calculated.
Explanation:To find the same value as 25% of 64, we need to express 25% in different formats and apply it to 64. Option B) 25/100 · 64 translates the percent into a fraction, then multiplies by 64. Option C) .25 · 64 converts the percentage directly into a decimal, again multiplying by 64. Both expressions will yield the same result, which is the value of 25% of 64.
Options A), D), and E) do not give the correct value. A) is simply multiplication without considering the percentage, D) is incorrect because dividing 64 by a fraction is equivalent to multiplying by its reciprocal, and E) is an incorrect fraction division that does not represent 25% of 64.
Therefore, the correct answers are B) and C).

Mr. Finch buys a pack of ground coffee. He uses the same amount of ground coffee for each cup of coffee he brews. The equation below describes the relationship between the number of cups brewed (x) and the ounces of coffee (y) remaining in the pack.
How much ground coffee, in ounces, was in the full pack?
A: 3
B: 6
C:15
D:18
I think it was C:15 but I am not exactly sure
The equation that relates the number of cups brewed to the ounces of coffee remaining is necessary to determine the initial amount of coffee in the pack, which is not provided in the question.
Explanation:The question does not provide the specific equation that describes the relationship between the number of cups brewed (x) and the ounces of coffee (y) remaining in the pack. However, the task is to determine how much ground coffee, in ounces, was in the full pack when Mr. Finch purchased it. To solve this, we would typically need to know how much coffee is used per cup and have an initial amount representing the full pack. If the equation was provided, we could use it to calculate the initial amount of the coffee. Without the equation, we cannot proceed with the calculation. Ensuring all critical information is provided in a word problem is crucial for solving it.
Which are solutions to 3sin^2 θ - 2sin θ = 0, 90°≤θ≤90°
Answer:
The solutions of the equation are -41.8° , 0.0° , 41.8°
Step-by-step explanation:
∵ 3 sin²Ф - 2 sinФ = 0 is a quadratic function
∵ The domain of the function is -90° ≤ Ф ≤ 90°
- Lets take sinФ as a common factor
∴ sinФ (3 sinФ - 2) = 0
- Two terms multiplied by each other = 0
∴ One of them must be equal zero
∴ sinФ = 0 or 3 sinФ - 2 = 0
- If sinФ = 0 ⇒ Ф = 0.0°
- If 3 sinФ - 2 = 0 ⇒ 3 sinФ = 2 ⇒ sin Ф = 2/3
∵ sinФ 2/3
∴ Ф = 41.8° ⇒ Ф ≤ 90° (in first quadrant)
∵ -90° ≤ Ф ≤ 90°
∴ Ф = -41.8° ⇒ Ф ≥ -90° (in fourth quadrant)
∴ The solutions of the equation are -41.8° , 0.0° , 41.8°
Step-by-step explanation:
Correct Answer is B and C 0.0, and 41.8

Jane orders cheese pizzas from a pizza restaurant that charges $8.00 per pizza. Jane has only $45.00 to spend on pizza. Jane’s cost in dollars is a function of the number of pizzas she orders
This question relates to the economic principle of a budget constraint. Jane can afford to purchase up to 5 pizzas with her budget, calculated via: Number of Pizzas = Total Budget / Unit Cost per Pizza.
Explanation:The subject of this question is related to an economic principle of budget constraint in mathematics. Here, Jane's budget constraint is her total budget of $45, and the unit cost per pizza is $8. The budget works as a restriction that states how many pizzas Jane can afford to buy. The number of pizzas she can buy can be calculated as her total budget divided by the unit cost per pizza.
Therefore, the question is asking you to determine how many pizzas Jane can afford to buy with her budget of $45. Using the formula Number of pizzas = Total budget / Unit cost per pizza, we get: Number of pizzas = $45 / $8 = 5.625.
Since Jane can't buy a fraction of a pizza, she can purchase up to 5 pizzas with her available budget.

Step-by-step explanation:
event q is more likely to occur then event t. the probability of event t is 1/2. what is a possible probability of event q?
Among the given options, option C) 2/3 is a possible probability for event Q that is greater than 1/2. Therefore, the correct answer is C) 2/3.
If event Q is more likely to occur than event T and the probability of event T is 1/2, then a possible probability of event Q could be any value greater than 1/2.
Let's dive deeper into the concept of probability and explore why option C) 2/3 is a possible probability for event Q.
When we say that event Q is more likely to occur than event T, it means that the probability of event Q is greater than the probability of event T. In this case, we are given that the probability of event T is 1/2.
To find a possible probability for event Q, select a value greater than 1/2. Option C) 2/3 fits this criterion. It indicates that event Q has a probability of 2/3, which is greater than 1/2.
Complete question
Event Q is more likely to occur than Event T. If P(Event T) = 1/2, what is a possible probability of Event Q? A)1/4 B)1/2 C)2/3 D)It cannot be determined.
The possible probability of event q is is [tex]\(\frac{3}{4}\).[/tex]
Since event Q is more likely than event T, the probability of event Q must be greater than the probability of event T.
The probability of event T is [tex]\(\frac{1}{2}\),[/tex] so the probability of event Q must be greater than [tex]\(\frac{1}{2}\).[/tex]
This satisfies the condition that event Q is more likely than event T because [tex]\(\frac{3}{4}\) (or 0.75)[/tex] is greater than [tex]\(\frac{1}{2}\) (or 0.5).[/tex]
It is important to note that there are infinitely many probabilities that are greater than [tex]\(\frac{1}{2}\)[/tex] and less than or equal to 1 (the maximum probability for any event).
However, the question asks for a possible probability, and [tex]\(\frac{3}{4}\) is[/tex] a valid example that meets the given criteria.
The student council at Woodland middle school is planning a field trip. They pulled it randomly selected teachers and students and asked what they want to eat for lunch. Results are shown in the table below.
I may be the second one because the first one says 19 percent of the people who polled that are teachers prefer burgers. And the second one says 19 percent of the teachers polled prefer burgers, so I think it is the second answer.
Answer:
Step-by-step explanation:
First question: 19% of those who prefered burgers were teachers. This is true. We focus on the "Burgers" column and ignore the rest of the table.
Second question: 19% of the teachers polled prefered burgers. This is false. If we look at the "teachers" line, we see that 6 teachers prefered pizza and 4 prefered burgers. The percentage of teachers prefering burgers was 4 / (4+6), or 4/10, or 40%.
Third question (impossible to read): 19% of the people polled prefer ..... .
False. That 19% does not pertain to the entire group of people polled.
