Find a fraction in between 21/34 and 34/55
Answer:
A fraction between that is 2311/3740
Step-by-step explanation:
This is because the denominator is simplified into one number and the fraction is taken from there.
2311/3740
Step-by-step explanation:34 = 2×17
55 = 5×11
LCM = 2×5×11×17 = 1870
⁵⁵⁾21/34 = ²⁾1155/1870 = 2310/3740
³⁴⁾34/55 = ²⁾1156/1870 = 2312/3740
2310/3740 < 2311/3740 < 2312/3740
The number 11 is increased to 12. What is the percentage by which the number was increased, to the nearest tenth of a percent?
Answer:
9.1%
Step-by-step explanation:
You can find this answer by dividing 12 by 11. When you do that, you get that 12 is 109.1% percent of 11. 11 is obviously 100% of 11, so it increased by the difference of the two percentages, 109.1-100 = 9.1%
A person came to work at 7:30am went out at 11:45am had lunch came in at 12:30pm and left at 5:15pm. How many hours did this person work?
Answer:
9 hours
Step-by-step explanation:
if they came in at 7:30 a.m and leaves at 11:45 a.m they have been there for 4 hours and 15 minutes.
If they arrive at 12:30 p.m and leave at 5:15 p.m they have been there for 4 hours and 45 minutes
so in total they have been there for 9 hours
In the 21st century, people measure length in feet and meters. At various points in
history, people measured length in hands, cubits, and paces. There are 9 hands in 2
cubits. There are 5 cubits in 3 paces.
a. Write an equation to express the relationship between hands, h, and cubits, c.
b. Write an equation to express the relationship between hands, h, and paces, p.
Answer:
The answer to b is 22.5 hands is 3 paces
Step-by-step explanation:

We want to find equations for changes of units, which allow us to change the units of a given measure to an equivalent value.
a) [tex]C = H*\frac{2c} {9h}[/tex]
b) [tex]P = H*\frac{6p}{45h}[/tex]
--------------------------------
We know two relations:
9 hands = 2 cubits.5 cubits = 3 paces.a) We want to find an equation to express the relationship between hands, h, and cubits, c.
Let's start with the relation:
9 hands = 2 cubits
we can rewrite:
[tex]1 = (2 c)/(9 h)[/tex]
Now suppose that we have a measure in hands, H.
If we multiply this measure by 1, we do not affect the measure, then we have:
[tex]H = H*1 = H*\frac{2c}{9h}[/tex]
Notice that we are dividing by hands, so we are cancelling the hands units, and we are multiplying by cubits, so we changed the units.
Then we can define C as the equivalent measure to H, such that C is in cubits.
[tex]C = H*\frac{2c}{9h}[/tex]
b) Similar to before.
Again, let's use H as a measure in hands.
With the relation:
[tex]C = H*\frac{2c}{9h}[/tex]
We change from hands to cubits.
Now with:
5 cubits = 3 paces.
We can write:
1 = 3p/5c
If we multiply our measure in cubits by the above fraction, we can change the units from cubits to paces, so we will have that P, the equivalent measure to H in paces is given by:
[tex]P = C*\frac{3p}{5c} = H*\frac{2c}{9h}*\frac{3p}{5c}= H*\frac{6p}{45h}\\\\P = H*\frac{6p}{45h}[/tex]

Solve the system of equations.
2y - 3x = -27
5y + 3r = 6
X= ?
Y= ?
Answer:
y = -3 x = 7
Step-by-step explanation:
2y - 3x = -27
5y + 3x = 6
3x cancels.
7y = -21
y = -3
Substitute y in 2y - 3x = -27
2(-3) - 3x = -27
-6 - 3x = -27
-3x = -21
x = 7
Solve the equation-3y = 21 using inverse operations. What is the inverse operation step? What is the solution?
Answer:
Y=-7
Step-by-step explanation:
The solution to the equation -3y = 21 is y = -7.
To solve the equation -3y = 21 using inverse operations, we want to isolate the variable y by performing the inverse operation.
Now, the inverse operation of multiplication by -3 is division by -3.
By dividing both sides of the equation by -3, we can isolate y.
Let's perform the inverse operation:
(-3y) / -3 = 21 / -3
y = -7
Therefore, the solution to the equation -3y = 21 is y = -7.

I need someone to help me find the missing value please.
Answer:
7
Step-by-step explanation:
Note the relation between x and y
The values of y are 2 less than the corresponding values of x, that is
x = - 3 → y = - 3 - 2 = - 5
x = 0 → y = 0 - 2 = - 2
x = 1 → y = 1 - 2 = - 1
x = 5 → y = 5 - 2 = 3
Thus
x = 9 → y = 9 - 2 = 7 ← missing value

Each spot in the triangle is the sum of the two numbers immediately above. The middle number of row 2 will be 1+1 = 2. The two numbers in row 3 will be 1+2 = 3 and 2+1 = 3. It continues like this. The second number in each row is the row number. Each row is symmetrical about the center.
The USDA reported that in 1990 each person in the United States consumed an average of 133 pounds of natural sweeteners. They also claim this amount has decreased by about 0.6 pounds each year. a. If 1990 could be considered year zero, which of the above numbers represents the slope and which represents the y intercept? b. What is the equation of the line of best fit using the slope and y-intercept above? c. Predict the average consumption of sweeteners per person for the year 2005.
Answer:
The problem implies that we want to write the (average) amount of natural sweeteners consumed per person as a function of time. Let y represent the (average) amount of natural sweeteners consumed per person (in pounds), and let x represent the time measured in years since 1990. That is, x = 0 represents 1990. If y is a linear function of x, then we can use the slope-intercept form y = mx + b (where m is the slope and b is the y-intercept) to write the function.
The slope can be interpreted as the rate of change of y with respect to x, which in this case means the change in consumption of natural sweeteners per year. The statement that consumption has decreased by 0.6 pounds per year tells us that the slope is m = -0.6 Also, the y-intercept is the same as the y-value of the function when x = 0. (In our case, that means time 0, that is, 1990.) Therefore the y-intercept is b = 133. Hope that helps! Let me know if you have any further questions.

Bethany’s mom made her a sandwich with a length of 8 cm and a height of 6 cm. If she cuts it in half diagonally as shown, what is the length of the cut edge?
Answer:
10
Step-by-step explanation:
a^2 + b^2 = c^2 (Pythagorean Theorem)
The length is 8(a)
The width is 6(b)
C is the unknown
8^2+6^2 = 100
then you need to square root the 100

A cell phone company charges $4 per GB beyond
20GB in a month. The monthly plan is $59.99, and
the bill for January is $75.99. How many GB were
used in that month?
Answer:
25GB was used that month
Step-by-step explanation:
Here, we want to calculate the GB used for the month.
Since we have $59.99 for 20GB, then the extra that brought the bill to $75.99 must have been from the beyond charges.
The extra charges is thus $75.99 - $59.99 = $20
Now, since $4 is charged as extra and we have a total of $20, the number of extra GB is thus 20/4 = 5
So the total GB for that month is 20 + 5 = 25GB

Explanation:
There is a theorem in geometry that says:
In a circle, if two chords are equal in measure, then their corresponding minor arcs are equal in measure.
Those small tick marks on each of the chords means that they are equal in measure. So, following the theorem, the arcs are also equal in measure.
If they are equal and
arc AB = arc CB
arc AB = 24 feet
Then
arc CB = 24 feet
by substitution.
