what is the sum of 2/10 + 6/100
Answer:
26/100 which is simplified to 13/50
Step-by-step explanation:
you have to get equal denominators so multiply 2/10 by 10 on top and bottom to get 20/100 then you can add 6/100 plus 20/100 which is 26/100 . denominators stay the same 26/100 can be simplified to 13/50
The sum of 2/10 and 6/100 is 13/50.
To find the sum of 2/10 and 6/100, we'll first find a common denominator and then add the fractions together.
The common denominator for 10 and 100 is 100, as it is the smallest multiple that both denominators can evenly divide into.
Now, we'll rewrite both fractions with the common denominator of 100:
2/10 = (2/10) * (10/10) = 20/100
6/100 = 6/100
Now that both fractions have the same denominator, we can add them together:
20/100 + 6/100 = (20 + 6)/100 = 26/100
Now, we have the sum of the fractions as 26/100. To simplify this fraction, we can divide both the numerator and denominator by their greatest common divisor, which is 2:
(26 ÷ 2) / (100 ÷ 2) = 13/50

Note: As you may have unintentionally missed to add the diagram. After a little research, I was able to find the diagram. I have attached the diagram, based on which I am solving which anyways would clear your concepts.
Answer:
The area of the storage facility is [tex]20x^2-4x-16\:\:square\:feet[/tex].
Step-by-step explanation:
From the attached diagram, it is clear that
The length of the rectangle [tex]=5x + 4[/tex]The width of the rectangle [tex]= 4x - 4[/tex]The area of the storage facility in square feet can be calculated by finding the area of rectangle.
So, using the area of rectangle formula
[tex]A = lw[/tex]
[tex]=\:\left(5x+4\right)\left(4x-4\right)[/tex]
[tex]\mathrm{Apply\:FOIL\:method}:\quad \left(a+b\right)\left(c+d\right)=ac+ad+bc+bd[/tex]

To find the area of the storage facility, calculate the area of each shape and add them together. The correct expression is 36x^2+24x.
Explanation:To find the area of the storage facility, we need to find the area of each individual shape and add them together. Looking at the diagram, we can see that the storage facility is composed of two rectangles and one square. Let's calculate the area of each shape:
Area of first rectangle = length x width = 4x(4x+4) = 16x^2+16x
Area of second rectangle = length x width = 4x(4x+2) = 16x^2+8x
Area of square = side x side = (2x)^2 = 4x^2
To find the total area, we add the areas of the three shapes:
Total area = (16x^2+16x) + (16x^2+8x) + 4x^2 = 36x^2+24x
Therefore, the correct expression that represents the area of the storage facility is 36x^2+24x, which is option B.

Bill buys a stock that decreases by 20% on the first day, and then on the second day the stock increases by 30% of its value at the end of the first day. What was the overall percent increase in Bill's stock over the two days?
Please answer someone!
The over all percent increase in Bill's stock over the two days is 4%
Step-by-step explanation:
The given is:
Bill buys a stock that decreases by 20% on the first dayOn the second day the stock increases by 30% of its value at the end of the first dayWe need to find what was the overall percent increase in Bill's stock over the two days
Assume that Bill buys the stock by $x
∵ Bill buys the stock by $x
∵ The stock decreases by 20% on the first day
- Find the 20% of x
∵ 20% × x = [tex]\frac{20}{100}[/tex] × x = 0.2 x
∴ The cost at the end of the 1st day = x - 0.2 x = 0.8 x
∵ The stock increases by 30% of its value at the end of the 1st day
- Find the 30% of 0.8 x
∵ 30% × 0.8 x = [tex]\frac{30}{100}[/tex] × 0.8 x = 0.3 × 0.8 x = 0.24 x
∴ The cost at the end of the 2nd day = 0.8 x + 0.24 x = 1.04 x
To find the percentage of increased find the increasing amount and divide it by the original cost, then multiply the quotient by 100%
∵ The increasing amount = 1.04 x - x = 0.04 x
∵ The percentage of increase = [tex]\frac{0.04x}{x}[/tex] × 100%
∴ The percentage of increase = 0.04 × 100% = 4%
The over all percent increase in Bill's stock over the two days is 4%

Hours Spent at Water Park A 2-column table with 4 rows titled Hours Spent at Water Park. Column 1 is labeled Hours with entries 4, 5, 6, 7. Column 2 is labeled Tally with entries 4, 5, 3, 4. Write a statistical question that might have been asked to gather the data. Then explain why it is statistical.
Answer:
The question is: How much time do people spend in the water park?It is a statistical because the answer comes from a sample instead of from the entire population.
Explanation:
Rewrite the table
Hours Spent at Water Park
Hours Tally
4 4
5 5
6 3
7 4
These data could be the results of a survey whose target was to detemine how many hours people spent at a water park.
The size of the sample should be the number of tally, which is 4 + 5 + 3 + 4 = 16.
And the question most likely was made at the exit of a water park, when the people were leaving the park.
Thus, the statistical question could be How much time do people spend in the water park?
It is a statistical because the survey is made to a sample of the people who went to the water park instead to all the people. All the people who go to the water park is the population about whom you want to determine how much time they spend in the water park, but,since it is impossible to survey all the people, you need to survey a sample.
The resulting values from a sample are named statistical. The values for an entire population are named parameters. A statistical permits to draw conclusions for populations using just one or more samples, which should be random samples.
Answer:
sample responce
Step-by-step explanation:
“How many hours did you spend at the water park today?” It is statistical because the responses will vary among individuals and the responses will be numeric.

The difference of 2x and 5 is greater than -3 and less than or equal to 11
The solution to the inequality is 1 < x ≤ 8.
The given inequality can be split into two components:
The difference of 2x and 5 is greater than -3: This can be written as:
2x - 5 > -3
To solve for x, we first add 5 to both sides of the inequality:
2x > 2
Then, we divide both sides by 2:
x > 1
This indicates that the values of x which satisfy this part of the inequality are greater than 1.
The difference of 2x and 5 is less than or equal to 11: This can be written as:
2x - 5 ≤ 11
Adding 5 to both sides:
2x ≤ 16
Dividing both sides by 2:
x ≤ 8
Therefore, the common range that satisfies both parts is 1 < x ≤ 8.

Omar buys candy that costs $8 per pound. He will spend at least $40 on candy. What are the possible numbers of pounds he will buy?
Use p for the number of pounds Omar will buy.
Write your answer as an inequality solved for p.
HELP ASAP
Omar will buy at least 5 pounds of candy. To find this, divide his minimum spending ($40) by the cost per pound of candy ($8). The inequality solved for p is p \geq 5, meaning Omar can buy 5 or more pounds of candy.
Explanation:To find out the possible number of pounds of candy Omar will buy, we can set up an inequality using the given information. We know the cost per pound of candy is $8, and Omar is going to spend at least $40 on candy. Therefore, the inequality representing the situation can be written as:
8 imes p \\(cost per pound \\ times number of pounds)\\ \geq 40 (Omar's minimum spending)
To solve for p, the number of pounds, we divide both sides of the inequality by 8:
p \geq \frac{40}{8} \Rightarrow p \geq 5
So, Omar will buy at least 5 pounds of candy. This means that the possible numbers of pounds he may buy are 5 or more.
