What is the value of the expression shown below?
10 + (2 x 3) to the power of 2 ÷ 4 × 1/2 to the power of 3
11 and 1/8
25 and 1/6
69
82
Answer:
11 and 1/8
Step-by-step explanation:
We can do this in the format of PEMDAS
Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction
10 + (2 × 3[tex])^{2}[/tex] ÷ 4 × [tex]\frac{1}{2} ^{3}[/tex]
Let's do the parenthesis first
10 + [tex]6^{2}[/tex] ÷ 4 × [tex]\frac{1}{2} ^{3}[/tex]
Now we can do the fraction with the exponent second
10 + [tex]6^{2}[/tex] ÷ 4 × [tex]\frac{1}{8}[/tex]
Now we can do the other exponent
10 + 36 ÷ 4 × [tex]\frac{1}{8}[/tex]
Now we can divide the 36 and 4
10 + 9 × [tex]\frac{1}{8}[/tex]
Now we can multiply the 9 and [tex]\frac{1}{8}[/tex]
10 + [tex]\frac{9}{8}[/tex]
And we can convert the improper fraction to a mixed number
10 + 1 1/8
And now we can add them up, the 2 whole numbers and the fraction stays the same
11 1/8
Hope this helped!

PLZ HELP. Rima wants to learn more about the heights of the students at Spring Valley Middle School. The school teaches students in grades 6 through 8. Each subject is taught by a different teacher, so students change classrooms every period. Students don’t have a class every period, but every student has a homeroom class. Consider five samples from this population, then answer the questions that follow. Sample A: Survey four random students in each of Rima's classes. Sample B: Survey two random students from each homeroom class. Sample C: Survey three random girls from every third-period class. Sample D: Survey every sixth person in the student directory. Sample E: Survey every third person in the band directory. Part A Is sample A a random sample? Why or why not?
Answer:
PART A: Sample A is not a random sample. In a random sample, all members of the population have an equal chance of being selected. Sample A has students from Rima’s classes, but no students from other classes. Students from the other two grades in the school won’t be represented.
PART B: Sample B is a random sample. Every student, or every member of the population, has a homeroom class. All of them have an equal chance of being selected in the sample.
PART C: Sample C is not a random sample because the sample excludes boys. The sample should include both girls and boys to represent the entire student population.
PART D: Sample D is a random sample. All students in all grades are featured in the student directory, so all of them have an equal chance of being picked for the sample.
PART E: Sample E is not a random sample because it consists of only the students in the band and excludes all other students from the sample. Because not every student is in the band, this is not a fair representation of the entire student body.
please give me brainlist thank you and have a good day :)
Answer:
PART A: Sample A is not a random sample.
PART B: Sample B is a random sample.
PART C: Sample C is not a random sample.
PART D: Sample D is a random sample.
PART E: Sample E is not a random sample.

Explain how you would find a precent increase or a percent decrease.
don't put I don't know or I don't know or ill report you
Answer:
You can find a percent increase because the percentage would go up. Like 30% if it increased it would go up too 50%. Which increased by 80%. And you can also add and subtract to make sure your answer is correct.
To find a deacrease it means that the percentage would go down. Like 80% to 60% is a decrease because it went down by 20%.

Answer:
[tex] \underline{ \underline{ \boxed{ \text{Subtract \: 2 \: from \: both \: sides}}}}[/tex]
Step-by-step explanation:
Since we want constants only on the right hand side , we have to remove 2 which is on the left hand side. The opposite of +2 is -2 and whatever we do to one side , we must do to the other side. So, The first step that would be used to solve the equation should be Subtract 2 from both sides.

If a is 3, b is 4, and c is 5, is the equation true or false?
Answer:
True
Step-by-step explanation:
a^2 + b^2 = c^2
(a) 3^2 = 9
(b) 4^2 = 16
(c) 5^2 = 25
9 + 16 = 25
25 = 25

The equation |x| = 100 has two solutions. x = -100 and x = 100 Write two solutions for each variable in the equations
a = 7 a = __________ and a = __________
p = 41 p = __________ and p = __________
y = 256 y = __________ and y = __________
I think you meant |a|=7, |p|=41, and |y|=256. In that case, a=7 or -7, p= 41 or -41, and y=256 or -256.
Painting:
Lisa is painting a fence that is 26 feet long and 7 feet tall. A gallon of paint will cover 350 square feet. Write and solve a proportion to determine how many gallons of paint Lisa will need
(Also can you explain how you solved it? Just in case I've been doing all the other ones wrong)
Answer:
Step-by-step explanation:
First we need to find the area of the fence, since paint covers square feet and squared units refers to area. The area of the fence is 26 x 7, which is 182 sq ft. If one gallon of paint will cover 350 sq ft, your proportion will look like this, with gallons of paint on top and square feet on the bottom. 1/350 = x/182 Cross multiply to get 350x = 182 and x = .52, just a bit over a half of a gallon of paint.

$12
$135
None of these
Question 10 (2 points)
An economist creates a scatter plot comparing years of experience to yearly salary (in dollars) at a particular company. The trend line through the data can be described by the equation y = 9,000x + 25,000.
What is the slope and what does it mean?
Question 10 options:
9,000; For their every year of experience an employee has, their salary goes up by this amount.
25,000; For their every year of experience an employee has, their salary goes up by this amount.
25,000; Regardless of how much experience an employee has, this is the minimum amount the employee will earn at this company.
9,000; Regardless of how much experience an employee has, this is the minimum amount the employee will earn at this company.
Answer:
Question 6: The slope is 5/3 because the y-intercpet is your rise and it rose up 5 units and x-intercept is your run so it shifted 3 units to the right which means the whole thing is also positive.
Question 9: $135
Question 10: Its either the first or last option
Step-by-step explanation:
Answer:
The answer for question 6 would be 5/3
and for question 9 the answer would be 135
and I believe question 10 is 9,000; For their every year of experience an employee has, their salary goes up by this amount.
Step-by-step explanation:
Slope (also can be called rate of change) is solved by change in the y variable/change in the x variable or also known as rise/run
