Add using a number line.
5/6 + (−1 1/6)
Drag and drop the word SUM to the correct value on the number line.
Answers
Answer:
-1
Step-by-step explanation:
We are given that an expression
[tex]\frac{5}{6}-\frac{11}{6}[/tex]
We have to find the correct value of given expression on the number line.
[tex]\frac{11}{6}=1\frac{5}{6}[/tex]
[tex]\frac{5}{6}-\frac{11}{6}[/tex]
[tex]\frac{5-11}{6}=\frac{-6}{6}[/tex]
[tex]\frac{5}{6}-\frac{11}{6}=-1[/tex]
[tex]\frac{5}{6}+(-1\frac{5}{6})[/tex]
When an integer positive and other integer negative and add them .If negative integer is greater and positive integer is small then we go from left to right.
We go [tex]\frac{5}{6}[/tex] step from [tex]-1\frac{5}{6}[/tex]towards right then we reach at [tex]{-1}[/tex].
Hence, -1 is the correct value of given expression.

which of the following is a solution to 4cos^2x-1=0?
60°
150°
210°
330°
Answers
Answer:
Option A- 60°
Step-by-step explanation:
Given : Function - [tex]4cos^2x-1=0[/tex]
To solve the function
Step 1 - Write the function
[tex]4cos^2x-1=0[/tex]
Step 2- Add 1 both side
[tex]4cos^2x=1[/tex]
Step 3- Divide 4 both side
[tex]cos^2x=\frac{1}{4}[/tex]
Step 4 - Taking root both side
[tex]cosx=\sqrt{\frac{1}{4}}[/tex]
Step 5 - solve
[tex]cosx=\pm{\frac{1}{2}}[/tex]
Either [tex]cosx={\frac{1}{2}}[/tex] or [tex]cosx=-{\frac{1}{2}}[/tex]
When [tex]cosx={\frac{1}{2}}[/tex]
[tex]\rightarrow cosx={cos\frac{\pi}{3}}[/tex]
[tex]\rightarrow x={\frac{\pi}{3}} or 60^{\circ}[/tex]
or when [tex]cosx=-{\frac{1}{2}}[/tex]
[tex]\rightarrow cosx={cos(\pi-\frac{\pi}{3})}[/tex]
[tex]\rightarrow x={\frac{2\pi}{3}} or 120^{\circ}[/tex]
Therefore, Option A is correct solution of function is at 60°.
The solution of the given trigonometric ratio for the expression 4cos²x - 1 = 0 is equal to 60°
To find the solutions to the equation 4cos²x - 1 = 0, we first need to isolate the cosine term and then solve for x.
Let's go through the steps,
Add 1 to both sides of the equation:
4cos²x = 1
Divide both sides by 4:
cos²x = 1/4
Take the square root of both sides:
cosx = ±√(1/4)
Now, we have two cases to consider: positive and negative square roots.
Case 1,
cosx = √(1/4)
The cosine of an angle can never be negative when expressed in degrees, so we ignore the negative square root.
cosx = √(1/4) = 1/2
To find the angles for which the cosine is 1/2, we look at the unit circle or use a calculator to find the inverse cosine (arccos) values:
x = arccos(1/2)
The principal angle that satisfies this is x = 60°.
Case 2,
cosx = -√(1/4)
Again, we ignore the negative square root as the cosine is not negative in degrees.
Therefore, the only solution to the equation is:
x = 60°
Therefore, among the given options, the solution to 4cos²x - 1 = 0 is 60°.

Floyd is an aspiring music artist. He has a record contract that pays him a base rate of $ 2 0 0 $200dollar sign, 200 a month and an additional $ 1 2 $12dollar sign, 12 for each album that he sells. Last month he earned a total of $ 6 4 4 $644dollar sign, 644. Write an equation to determine the number of albums ( a ) (a)left parenthesis, a, right parenthesis Floyd sold last month. Find the number of albums Floyd sold last month.
Answers
x=number of albums sold
y=$200+12x
Want to solve for x
(y-$200)/12=x
y=644
(644-200)/12=x
444/12=x
x=37 albums
To find the number of albums Floyd sold last month, we calculate it using the linear equation $644 = $200 + ($12 \u00d7 a), where $644 is the total earnings, $200 is the base rate, and $12 is the amount earned per album. Floyd sold 37 albums last month.
Explanation:To determine the number of albums Floyd sold last month, we can set up a linear equation based on the information provided. Floyd is paid a base rate of $200 per month, and he earns an additional $12 for every album sold. The total amount Floyd earned last month was $644.
Let's let a represent the number of albums sold. The equation that represents the total earnings for the month would be:
Total Earnings = Base Rate + (Number of Albums Sold × Price per Album)
Based on what has been given, we can express this as:
$644 = $200 + ($12 × a)
To find the number of albums sold, we subtract the base rate from the total earnings, then divide by the additional amount earned per album:
$644 - $200 = $12 × a
$444 = $12 × a
a = $444 / $12
a = 37
So, Floyd sold 37 albums last month.

suppose that Y and Z are points on the number line if YZ=11 and Y lies on -9 where would Z be located
Answers
Final answer:
Point Z is located at 2 on the number line, found by adding the distance YZ=11 to the location of Y at -9.
Explanation:
If Y and Z are points on the number line, YZ=11, and Y lies on -9, to find where Z would be located, you simply add the distance between Y and Z to the point Y. Since the distance YZ=11, and Y is at -9 on the number line, you add 11 to -9 to find Z.
Therefore, the location of point Z will be:
-9 + 11 = 2
So, point Z is located at 2 on the number line.

in January 2011 the rate of VAT increased from 17.5% to 20%
work out the difference in price of a car worth £15000 +VAT due to increase in VAT
Answers
The difference in price of a car is £375 it is due to the rate of VAT increase from 17.5% to 20% and this can be evaluated by the help of unitary method.
Given :
Rate of VAT increased from 17.5% to 20%.
Total price of a car = £15000 + VAT.
In this problem unitary method can be used to determine the difference in price of a car which is due to the increased rate of VAT.
The price of VAT when its' rate is 17.5% can be:
[tex]= \dfrac{15000}{100} \times 17.5[/tex]
= £ 2625
Therefore, the total price of car when VAT is 17.5% is £17625.
The price of VAT when its' rate is 20% can be:
[tex]= \dfrac{15000}{100} \times 20[/tex]
= £ 3000
Therefore, the total price of car when VAT is 20% is £18000.
So, the difference in price of car = 18000 - 17625 = £375.

Farmer Ed has 3,500 meters of fencing, and wants to enclose a rectangular plot that borders on a river. If Farmer Ed does not fence the side along the river, what is the largest area that can be enclosed?
Answers
Answer:
Because it is a rectangle, the area is expressed as A = xy, or length times width.
Step-by-step explanation:
Because it is next to the river, he only needs to fence three sides, so F = x + 2y.
Knowing the amount of fencing available is 7500m, we get:
7500 = x + 2y solve for x
x = 7500 - 2y substitute into the area equation
A = (7500 - 2y)y distribute
A = -2y2 +7500y
You can see that this is a parabola which opens down, meaning that the point of maximum area will be at the vertex, y = -b/2a = -7500/[2(-2)] = 1875
x = 7500 - 2(1875) = 3750
A = 3750(1875) = 7,031,250 m2
If Farmer Ed has 3,500 meters of fencing, and wants to enclose a rectangular plot that borders on a river. If Farmer Ed does not fence the side along the river, Then 7,031,250 is the largest area that can be enclosed.
What is Rectangle?A rectangle is a closed 2-D shape, having 4 sides, 4 corners, and 4 right angles (90°).The opposite sides of a rectangle are equal and parallel.
As it is next to the river, he only needs to fence three sides, so F = x + 2y.
Knowing the amount of fencing available is 7500m, we get:
7500 = x + 2y
solve for x
x = 7500 - 2y
substitute into the area equation
A = (7500 - 2y)y
Distribute
A = -2y2 +7500y
You can see that this is a parabola which opens down, meaning that the point of maximum area will be at the vertex, y = -b/2a = -7500/[2(-2)] = 1875
x = 7500 - 2(1875) = 3750
A = 3750(1875) = 7,031,250 m².
Hence 7031250 is the largest area that can be enclosed.
