whats the reciprocal of 1 8/11
First, change the mixed fraction into improper fraction. Change the whole number into a fraction, and add.
1 8/11 = 11/11 + 8/11 = 19/11
To find the reciprocal, flip the fraction.
The reciprocal of 19/11 is 11/19
hope this helps
Final answer:
The reciprocal of 1 ⁸/₁₁ is 11/19, which is calculated by first converting the mixed number to an improper fraction (19/11) and then flipping the numerator and denominator to get the reciprocal.
Explanation:
To find the reciprocal of 1 ⁸/₁₁ , you first need to convert the mixed number to an improper fraction. To do this, multiply the whole number by the denominator, add the numerator, and then write the result over the original denominator. In this case, 1 ⁸/₁₁ becomes (1×11 + 8)/11, which simplifies to 19/11.
Now, the reciprocal of a fraction is obtained by flipping the numerator and denominator. So the reciprocal of 19/11 is 11/19. Therefore, the reciprocal of 1 ⁸/₁₁ is 11/19.
Understanding the concept of reciprocals is important in mathematics because dividing by a number is the same as multiplying by its reciprocal. In this context, dividing by 1 8/11 is equivalent to multiplying by 11/19.

Wed. 3.9
Thurs. x
Fri. x
after everything you've ran the total would be 9.7 but you'll need to run a total of 13.1 so you still need to run 3.4 miles so you Thursday and Friday you'll run 1.7 each.
How would you describe the shape of
ribution?
Answer:
Normal distribution
Step-by-step explanation:
A normal distribution can be easily identified if you can see a "bell shape/curve" in the plotted bar chart or line chart.
With regard to a Bat chart a normal distribution can be identified when most of the tall bars are in the middle and when going from middle to both left and right you see the height of the bars dropping at the same rate both ways.
I have attached an image by editing your attachment. I have shown the "bell shape/curve" or the normal distribution.

A robot travels from position A to B to C to D, What composition of rigid motions represents those moves?
Assuming each movement is in a straight line, the composition
T <1,3> o T <4,0> o T <2,3>represents the moves.
Each movement is in a straight line, the composition represents the moves <-5, 1>, <-3, 4>, <1, 4> and <2, 7>.
Given that, a robot travels from position A to B to C to D.
We need to find what composition of rigid motions represents those moves.
What is the composition of rigid motions?Any way of moving all the points in the plane such that
a) the relative distance between points stays the same and
b) the relative position of the points stays the same.
There are four types of rigid motions that we will consider: translation, rotation, reflection, and glide reflection.
In a translation, everything is moved by the same amount and in the same direction. Every translation has a direction and a distance.
Therefore, each movement is in a straight line, the composition represents the moves <-5, 1>, <-3, 4>, <1, 4> and <2, 7>.

6e - 7f = 8g + h, solve for f
Isolate the f. Note the equal sign. What you do to one side, you do to the other.
First, subtract 6e from both sides
6e (-6e) - 7f = 8g + h (-6e)
-7f = 8g + h - 6e
Divide -7 from both sides
(-7f)/-7 = (8g + h - 6e)/-7
f = -8/7g + h/-7 + 6/7e
f = -8/7g + h/-7 + 6/7e is your answer

you put a frozen pizza in the microwave. Let T(m) be the function that represents the temperature in F of the pizza after m minutes
A. write a sentence explaining what T(0)=30 means
B. write a sentence explaining what T(5)=80 means
C. write a sentence explaining what T(3) is less than f(4) means
T(0) = 30 means the temperature of the pizza is 30 degrees Fahrenheit. T(5) = 80 means the temperature of the pizza is 80 degrees Fahrenheit after 5 minutes. T(3) is less than T(4) means the temperature of the pizza after 3 minutes is lower than after 4 minutes.
Explanation:A. T(0) = 30 means that when the frozen pizza is put in the microwave, the temperature of the pizza is 30 degrees Fahrenheit.
B. T(5) = 80 means that after 5 minutes in the microwave, the temperature of the pizza is 80 degrees Fahrenheit.
C. T(3) is less than T(4) means that after 3 minutes in the microwave, the temperature of the pizza is lower than the temperature of the pizza after 4 minutes.
Last month, Carter ran 48 miles. This was 60% of his goal. How many miles did Carter set as his goal?
Answer: 80 miles.
Step-by-step explanation:
1. You have the following information given in the problem above:
- Carter ran 48 miles.
- 48 miles was 60% of Carter's goal.
2. Then, to calculate the number of miles that Carter set at his goal, you need to divide 48 miles by 60 and multiply this by 100, as following:
[tex](\frac{48}{60})(100)=80[/tex]
3. Therefore, the answer is 80 miles.

Rhonda worked three more than twice as many hours as Chris did. How many hours did each work if together they worked 57 hours
Answer:
Rhonda: 39 hours; Chris: 18 hours.
Step-by-step explanation:
If you subtract the extra 3 hours from the total, you have Chris's hours plus twice Chris's hours adding to 54. That is, Chris worked 54/3 = 18 hours, and Rhonda worked 57-18 = 39 hours = 2·18 +3 hours.
_____
If you insist on equations, you can write two of them:
... r = 2c +3
... r + c = 57
Substitute for r in the second equation:
... (2c +3) +c = 57
... 3c +3 = 57 . . . . . from here down, the explanation above matches this math
... 3c = 54
... c = 54/3 = 18
... r + 18 = 57 . . . . . . substitute for c in the second equation
... r = 57 - 18 = 39
A room’s floor is y meters long. It’s width is 5 meters shorter. If the perimeter of the floor is (4y + 1) meters, can you solve for it’s length?
We know that the perimeter of a rectangle is:
[tex]P=2L+2W[/tex] (1)
Where:
P is the perimeter
L: it's the long
W: is the width
They tell us that the perimeter is:
(4y + 1)
The long is y
The width is y-5.
Then we can write equation (1) as follows:
[tex](4y + 1)=2y+2(y-5)[/tex]
[tex]4y+1=4y-10\\[/tex]
[tex]1 = -10\\[/tex]
The equation can not be solved and, therefore, it is not possible to find the value of "y" with the information provided.

Please simplify the following distributive property expression:
7(x-4)
Final answer:
To simplify 7(x-4), distribute 7 over x and -4 to get 7x - 28. This is an application of the distributive property in algebra.
Explanation:
To simplify the expression 7(x-4) using the distributive property, you multiply the number outside the parenthesis, which is 7, by each term inside the parenthesis. The distributive property allows us to remove the parentheses by distributing the multiplication over the subtraction within.
Here is the step-by-step simplification:
Multiply 7 by x, which is 7x.
Multiply 7 by -4, which is -28.
Combine the results to get 7x - 28.
Therefore, 7(x-4) simplifies to 7x - 28.
I am a whole number. When rounded to the nearest ten, the answer is 210. The sum of my digits is 4. What number am I?
i think the answer is 214 i am not sure but i think it is
The number you are looking for is 211.
To find the number that meets the given criteria, we need to consider a few steps
1. The number, when rounded to the nearest ten, is 210.
2. The sum of the digits of the number is 4.
First, let's consider the numbers that round to 210 when rounded to the nearest ten. These numbers fall within the range of 205 to 214 (inclusive).
Next, let's identify which of these numbers has digits that sum to 4.
- 205: (2 + 0 + 5 = 7)
- 206: (2 + 0 + 6 = 8)
- 207: (2 + 0 + 7 = 9)
- 208: (2 + 0 + 8 = 10)
- 209: (2 + 0 + 9 = 11)
- 210: (2 + 1 + 0 = 3)
- 211: (2 + 1 + 1 = 4)
- 212: (2 + 1 + 2 = 5)
- 213: (2 + 1 + 3 = 6)
- 214: (2 + 1 + 4 = 7)
From this list, the number 211 is the only number within the range that has digits summing to 4.

Carlos raced around a 15-mile loop of track 25 times. What was the total distance of the race?
Answer:
375
Step-by-step explanation:
Did it on Edge
The total distance of the race is 375 miles.
Given data:
To find the total distance of the race, multiply the distance of the loop by the number of times Carlos raced around it.
Total distance = Distance of the loop * Number of times raced
Distance of the loop = 15 miles
Number of times raced = 25
Substituting the values into the formula:
Total distance = 15 miles * 25
On simplifying the equation:
Calculating the product:
Total distance = 375 miles
Hence, the total distance was 375 miles.
