Answer:6/7
Step-by-step explanation:
2/7 divided by 1/3= 2/7 x 3/1= 6/7
Answer:
Step-by-step explanation:
To divide fractions, use the reciprocal (flip it) of the second fraction and change the division sign to a multiplication sign.
So then the expression would be: [tex]\frac{2}{7} *\frac{3}{1}[/tex]
Then multiply like normal.

x² - 9 / х^2 - 3x
Answer:
[tex]\frac{x+3}{x}[/tex]
Step-by-step explanation:
Factorise numerator and denominator
x² - 9 ← is a difference of squares and factors in general as
a² - b² = (a - b)(a + b) , then
x² - 9
= x² - 3² = (x - 3)(x + 3)
x² - 3x ← factor out x from each term
= x(x - 3)
Then
[tex]\frac{x^2-9}{x^2-3x}[/tex]
= [tex]\frac{(x-3)(x+3)}{x(x-3)}[/tex] ← cancel common factor (x - 3) on numerator/denominator
= [tex]\frac{x+3}{x}[/tex]

A. There is no line that passes through the endpoints of a diameter of a
sphere.
B. There is only one line that passes through the endpoints of the diameter of
a sphere.
C. There are infinitely many points that pass through the endpoints of the
diameter of a sphere.
D. There are infinitely many lines that pass through two points on a sphere that
are not the endpoints of a diameter.
Answer:
A
Step-by-step explanation:
There is only one line that passes through the endpoints of the diameter of a sphere. Option B are correct.
Given that,
In spherical geometry, which of the following statements is true is to be determined.
A line is a straight curve connecting two points or more showing the shortest distance between initial and final points.
A.
False, because there are two endpoints of the diameter so a line minimum required two to get constituents.
B.
True, because online one line can constitute the two points, not more than one line can.
Similarly,

Agatha drives 73 1/2 miles through two towns in 2 1/3 hours. What is her average speed in miles per hour?
Answer:
31 1/2
Step-by-step explanation:
average speed = distance/time
average speed = (73 1/2 miles)/(2 1/3 hours)
= (147/2 miles)/(7/3 hours)
= 147/2 * 3/7 miles/hour
= 441/14 miles/hour
= 31 1/2 miles/hour
what is the percent change from 450 to 117
Answer:
Change ≈ 284.6154%
Step-by-step explanation:
To calculate the percent change of two numbers such as 450 to 117, you use the Percent Change Formula, where a is the start value and b is the end value.
(b-a)/a x 100
When we insert a = 450 and b = 117 in the formula above, then we get the following that we can simplify and solve to get the percent change from 450 to 117.
(117-45)/450 x 100
-333/450 x 100
Change = -74%
Now you know that the percentage change from 450 to 117 is -74%. Since it is a negative answer, it means that if you subtract 74% from 450, then you will get 117.

Find the slope and y-intercept of the graph of the linear equation.
y+3=2/3x
Answer:
Slope: 2/3
y-intercept: -3
Step-by-step explanation:
Subtracting both sides of the equation by 3 to make it in 'y=mx+c' form:
y + 3 - 3 = 2/3x - 3
y = 2/3x - 3
Seeing this,
m = 2/3
c = -3
Since m is the slope, the slope is 2/3
Since c is the y-intercept, the y-intercept is -3
Hope this helps and have a wonderful time ahead at Brainly! :D
Convert to Slope-Intercept Form to graph 3x + 2y = 8.
Answer:
y= - 3/2x+4 or y= - 1.5x+4
Step-by-step explanation:
Slope Intercept Form: y=mx+b
3x+2y=8
2y= - 3x+8
y= - 3/2x+4 or y= - 1.5x+4
Convert to Slope-Intercept Form to graph 3x + 2y = 8.The Slope : -3/2The y-intercept: y = -3x/2 + 4
What is Slope?
The ratio of how much y grows as x grows by a certain amount is known as a line's slope. The slope of a line indicates how steep it is, or how much y rises as x rises. Anywhere along the line, the slope remains constant (the same).
Solve the equation for y resulting in the y = mx + b
Where,
m = slope
b = the y intercept think b beginning.
3x + 2y = 8
Subtracting 3x both side
3x + 2y - 3x = 8 - 3x2y = 8 - 3x
Dividing both side by 22y/2 = 8/2 - 3x/2y = 4 - 3x/2y = -3x/2 + 4
So, m = -3/2and b = 4
Hence, Slope-intercept is y = -3x/2 + 4

Jalen made $533.75 while working at his job. He makes $15.25 an hour, how many hours did he work to make that amount of money?
Answer:
35 hours
Step-by-step explanation:
Typically, people get their paycheck after 2 weeks.
Let say he worked 8 hours a day, a typical amount of hours for the average human who has a occupation.
Multiply the amount of hours by the amount payed every hour.
So 15.25 x 8 is 122
( so in 8 hours jalen made $122)
Add 8 hours, which would now be 16 hours worked.
16 x 15.25 = 244
(so in 16 hours jalen made $244)
Add another 8 hours of work time which would now be 24 hours (1 full day)
24x5.25=366
Add 10 hours on now which would be 34 hours worked (2 days = 48 hours meaning she worked 1 day and 10 hours )
34x15.25=518.50
(getting closer to the amount she earned)
So if we add another hour
which would be 35 hours worked (1 day 11 hours)
35 x 15.25 = 533.75
Therefore, Jalen worked 35 hours.
After enlarging his "U" in problem 3-26, Al has an idea. He drew a 60° angle, as shown in Diagram #1 at
right. Then, he extended the sides of the angle so that they are twice as long, as shown in Diagram #2.
"Therefore, the new angle must have measure 120°," he explained. Do you agree? Discuss this with your
team and write a response to Al.
When extending both sides of an angle, you are not changing the angle, so dat man wrong....
Answer: Don't agree
