Elliot is moving a table through a doorway. The table is 2 and StartFraction 5 Over 8 EndFraction ft wide and the doorway is 2 and three-fourths ft wide. Which statement explains if the table will fit through the door?
The table will fit because 2 and StartFraction 5 Over 8 EndFraction < 2 and three-fourths.
The table will fit because 2 and StartFraction 5 Over 8 EndFraction > 2 and three-fourths.
The table will not fit because 2 and StartFraction 5 Over 8 EndFraction < 2 and three-fourths.
The table will not fit because 2 and StartFraction 5 Over 8 EndFraction > 2 and three-fourths.
Answer:
The table will fit
Step-by-step explanation:
Table: 2 3/8 = 19/8
Door: 2 3/4 = 11/4
(Mixed fraction to Improper fraction)
Door: 2 3/4 = 11/4 = 11/4*2 = 22/8
19/8 (Table) > 22/8 (Door)

Hans spent a total of $30 at the grocery store. Of this amount, he spent $21 on fruit. What percentage of the total did he spend on fruit?
Answer: 70%
Step-by-step explanation:
The total answers count 30 - it's 100%, so to get a 1% value, divide 30 by 100 to get 0.30. Next, calculate the percentage of 21: divide 21 by 1% value (0.30), and you get 70.00%
Here is a rectangle.
4.3 cm
7 cm
7 cm
4.3 cm
The 6-sided shape is made from two of these rectangles.
Work out the perimeter of this 6-sided shap
Answer:36.6cm
Step-by-step explanation;
you can make a six sided shape by keeping the two rectangles as it makes the shape of L
perimeter = 2(4.3cm)+4(7cm)
=8.6cm=28cm
=36.6cm
The perimeter of the 6-sided shape assuming it jointly at 4.3 cm sides will be 36.6 cm.
What is the perimeter?Perimeter is the addition of an external measure of sides it will always positive.
A perimeter is a length and has a degree of the unit as one.
The perimeter of the circle = πd where d is the dia of the circle.
As per the drawn combined rectangle.
Perimeter = 2(4.3) + 4(7)
⇒ 36.6 cm
Hence "The perimeter of the 6-sided shape assuming it jointly at 4.3 cm sides will be 36.6 cm".

Part A: To draw triangles ABC and DEC separately, follow these steps:
Draw a line segment DE with a length of 1.2 feet. This will be the base of both triangles.At point D, draw a perpendicular line segment DC with a length of 2 feet. This will be the height of triangle DEC.At point E, draw a line segment EB with a length of 0.3 feet. This will be the height of triangle ABC.Connect points C and B with line segment BC. This will be the hypotenuse of both triangles.What is the others about?The lengths of sides BC, DE, and EC are as follows:
BC: It is the hypotenuse of triangle ABC and has a length that needs to be calculated using the Pythagorean theorem.DE: It is the base of both triangles and has a length of 1.2 feet.EC: It is the height of triangle DEC and has a length of 2 feet.Part B: To find side AB of triangle ABC, we can use the concept of similarity and ratios. Since triangles ABC and DEC are similar, their corresponding sides are proportional. We can set up the following proportion:
AB/DE = BC/EC
Plugging in the given values, we get:
AB/1.2 = BC/2
To solve for AB, we can cross-multiply and then divide:
AB = (BC/2) x 1.2
Now we need to find the value of BC. We can use the Pythagorean theorem, as BC is the hypotenuse of triangle ABC. The Pythagorean theorem states that the square of the hypotenuse is equal to the sum of the squares of the other two sides.
BC² = AB² + BE²
Plugging in the given value for BE, we get:
BC^2 = AB² + 0.3²
Now we can substitute the value of AB from the previous equation into this equation:
BC² = ((BC/2) * 1.2)² + 0.3²
Simplifying, we get:
BC² = 0.36 x BC^2/4 + 0.09
Multiplying both sides by 4 to eliminate the fraction, we get:
4 x BC² = 0.36 x BC² + 0.36 + 0.09
Combining like terms, we get:
4 x BC² = 0.36 BC² + 0.45
Subtracting 0.36 x BC² and 0.45 from both sides, we get:
3.64 x BC² = 0.45
Dividing both sides by 3.64 to isolate BC², we get:
BC² = 0.45 / 3.64
Taking the square root of both sides to solve for BC, we get:
BC ≈ √(0.45 / 3.64)
BC ≈ 0.357 feet
Now we can substitute the value of BC back into the equation for AB:
AB = (BC/2) x 1.2
AB ≈ (0.357/2) x 1.2
AB ≈ 0.214 feet
So, the approximate length of side AB of triangle ABC is 0.214 feet.

How did you decide where to place your line of best fit? Describe your reasoning.
Based on your data, describe the relationship between age and the number of U.S. states a person can name in 60 seconds.
Do you see any areas in your data or points that could be considered clusters or outliers? Explain your answer in complete sentences.
Trolls will be reported
Answer:So I don’t know the other 5 points because you didn’t give the data about the age and number of US states named in 60 seconds, but using the 5coordinate points you gave, I was able to make this line of best fit.
So basically the units are counting up by 5.
The x axis is age in years and y axis is the number of US states named in 60 seconds.
Since you didn’t give me the data to make the other 5 points, I can’t really answer the last question, but from the graph that I did make, there are no points that would be considered outliers, and there are no clusters in sight.
(BTW THIS IS IMPORTANT!! - when you use the data to add the other 5 points, there might be an outlier or more then one outlier. And there might be a cluster. Just look at it after you graph the last 5 and change the answer I gave you if there is an outlier or cluster)

Answer:
\(f^{-1}\left(f(576)\right)=\boxed{576}\)
\(f^{-1}(-7)+f(-7)=\boxed{13}\)
Step-by-step explanation:
The inverse of an invertible function with the domain of all real numbers is obtained by reflecting the original function across the line y = x, which swaps the input and output values of the function. Therefore, (x, y) → (y, x).
Given table:
\(\begin{array}{lrrrrrr}\vphantom{\dfrac12}x&-7&11&-13&6&5&-9\\\cline{1-7}\vphantom{\dfrac12}f(x)&7&12&8&-7&13&5\end{array}\)
Inverse function:
\(\begin{array}{lrrrrrr}\vphantom{\dfrac12}x&7&12&8&-7&13&5\\\cline{1-7}\vphantom{\dfrac12}f^{-1}(x)&-7&11&-13&6&5&-9\end{array}\)
If we have a function f(x), the inverse function is denoted as f⁻¹(x), and it has the property that f⁻¹(f(x)) = x for all valid inputs x in the domain of f(x).
Therefore:
\(\large\boxed{f^{-1}\left(f(576)\right)=576}\)
The value of f(-7) is the value of f(x) when x = -7. Therefore, reading from the original table, f(-7) = 7.
The value of f⁻¹(-7) is the value of f⁻¹(x) when x = -7. Therefore, reading from the inverse function table, f⁻¹(-7) = 6.
Therefore:
\(\large\boxed{\begin{aligned}f^{-1}(-7)+f(-7)&=6+7\\&=13\end{aligned}}\)
