Answer: 6
Step-by-step explanation:
3/4 divided by 1/8 is the same as 3/4 multiplied by the reciprocal of 1/8( which is 8) therefore, 3/4 ×8=6
This can help you remember how to multiply fractions :Dividing fractions is easy as a pie, flip the second number and multiply, and don't forget to simplify, before its time to say goodbye.

Find the unknown side length of the rectangle is 3 2/3 and if the area is 11m2
Answer:
The width of the rectangle given is equal to 3m.
Step-by-step explanation:
In order to solve this question we need to know that the areas of the rectangle is equal to [tex]A_{rectangle} = (l)(w)[/tex], where "l" is length and "w" is width. So know in order to solve this question we would have to find out the unknown width by using area and the length of the triangle. Based on the formula I wrote down earlier we can understand the following.....
[tex]A_{rectangle} = (l)(w)[/tex]
[tex]\frac{A_{rectangle} }{l} = \frac{(l)(w)}{l}[/tex]
[tex]w = \frac{A_{rectangle} }{l}[/tex]
Just now we found out the formula that we can use to solve for the width when we know the area and the length of the rectangle. Now in order to get the answer we just have to plug in the values we know, and we get........
[tex]w = \frac{A_{rectangle} }{l}[/tex]
[tex]w = \frac{11m^{2} }{(3\frac{2}{3}m )}[/tex]
[tex]w = 3m[/tex]
Your brother traveled 117 miles in 2.25 hours to come home for Christmas. What's the average speed that he was traveling?
Answer:
52 miles per hour
Step-by-step explanation:
The formula for Average speed is given as: Distance(miles)/Time in hours
From the question,
Distance = 117 miles
Time = 2.25 hours
Average Speed = 117 miles/2.25 hours
Average Speed = 52 miles per hour
The average speed that he was traveling is 52 miles per hour

Solve these two equations:
For the first one we divide every element by sqrt3
we get
q+2/sqrt3 =sqrt5/sqrt3
q=(sqrt5-2)/sqrt3
q=sqrt3*sqrt5-2*sqrt3/3
q=sqrt15-2sqrt3/3
which is the third option
For the second one
sqrt(2y-5) +4=8
first we move the 4 to the right
sqrt(2y-5)=4
we remove the square root by bringing to the power of two
2y-5=16
2y=21
y=21/2
y=10 1/2

Kaitlyn start a job that pays $8.50 per hour Caitlin's manager says that if her job reviews were favourable she can expect annual pay rate increases of $0.75 which equation represents the relationship between years on the job and pay for our
Given:
Initial pay rate = $8.50 per hour
Increase in pay rate = $0.75 per year
To find:
The equation that represents the relationship between years on the job and pay for hour.
Solution:
Let x be the number of years and y be the pay rate after x years.
According to the question,
Increase in pay rate in 1 year = $0.75
Increase in pay rate in x year = $0.75x
So, variable pay rate = $0.75x
Initial pay rate = $8.50
So, the total pay rate is
Total pay rate = Initial pay rate + Variable pay rate
[tex]y=8.50+0.75x[/tex]
Therefore, the required equation is [tex]y=8.50+0.75x[/tex].

A garden hose fills a 2-gallon bucket in 5 seconds. The number of gallons, g (/), is proportional to the number of
seconds, t (x), that the water is running.
What is the constant of proportionality? k=-
help
Answer:
The constant of proportionality = k = 2/5
Step-by-step explanation:
Given that a garden hose fills a 2-gallon bucket in 5 seconds.Also given that The number of gallons, g (/), is proportional to the number of
seconds, t (x).
i.e.
g ∝ t
g = k × t
k = g / t
as
g = 2
t = 5
Thus,
k = g / t
= 2 / 5
Thus, the constant of proportionality = k = 2/5

Complete the table below for the function y = -6x + 4.
16. IF X= 31, then what is the perimeter of triangle JMN?
Answer:
180
Step-by-step explanation:
To solve we must first plug 31 into each expression for x.
2(31)+5= 67
3(31)-9= 84
31-2= 29
Then, remember that the perimeter is the sum of all of the sides. So add all of the previous sums, 67+84+29. Therefore, the answer is 180.

What is the direct variation equation if Y varies directly with X and Y equals negative 12 when X equal 6
Step-by-step explanation:
y = kx, where k is a real constant.
When x = 6, y = -12:
(-12) = (6)k
Therefore k = -2.
Hence y = -2x.
The direct variation of Y with X is Y = -2X.
What is an equation?Equation: A declaration that two expressions with variables or integers are equal. In essence, equations are questions, and attempts to systematically identify the solutions to these questions have been the driving forces behind the creation of mathematics. Simple algebraic equations with merely addition or multiplication to differential equations, exponential equations with exponential expressions, and integral equations are examples of different types of equations. They are employed to represent a number of physics laws.
As per the given data:
Y varies directly with X.
Y equals -12 when X equal 6.
Let's consider the equation Y = kX:
∴ -12 = k(6)
k = -2
Y = -2X
Hence, the direct variation of Y with X is Y = -2X.

A thermometer manufacturer compares the reading on one of its thermometers to a thermometer that they know is accurate. The accurate thermometer reads 25 degrees Celsius. Their thermometer reads 30 degrees Celsius. What is the percent error in their thermometer's reading?
A.2%
B.20%
C.83%
D.16%
Answer:
B. 20%
Step-by-step explanation:
Percentage Error = (Actual Value - Expected Value) / Expected Value * 100
Actual Value = 30
Expected Value = 25
Percentage Error = (30 - 25) / 25 * 100
Percentage Error = (5) / 25 * 100
Percentage Error = 0.2 * 100
Percentage Error = 20

Answer:
$45
Step-by-step explanation:
so where the line intercepts the 2 hours is $45, and to find the .25 hours we take the $20 for working one hour and divide that by four, because .25 is 1/4 of an hour. so 20/4 is five. then you add 5 to 40 and we get $45 for work 2.25 hours. hope that helped
