Answer:
7/3
Step-by-step explanation:
Use keep change flip
7×3=21 9×1=9
21/9=7/3
[tex]\frac{7}{9}[/tex]
Remember the rule for dividing fractions, keep, change, flip.
Keep the first fraction, change the division sign to a multiplication sign, flip the 2nd fraction, or find the reciprocal of the second fractions.
[tex]\frac{7}{9}[/tex]÷[tex]\frac{1}{3} = \frac{7}{9} * \frac{3}{1} = \frac{21}{3} = 7[/tex]

Answer:
10 units.
Step-by-step explanation:
In order to solve this, we first need to know the distance of the points by using rise and run. Then we will be able to find the hypotenuse. This is pretty much gonna make a triangle.
Run = 6
Rise = 8
We can use Pythagorean Theorem to solve for the hypotenuse since this forms a right triangle.
6² + 8² = c²
36 + 64 = c²
100 = c²
10 = c
Therefore, the distance between the two points is 10 units.
Answer:
10
Step-by-step explanation:
[tex]8^{2}[/tex] + [tex]6^{2}[/tex] = [tex]\sqrt{100}[/tex] = 10

This table shows values that represent an exponential function.
what is the average rate of change for this function for the interval from x=2 to x=4?
Answer:
Subtract the two Y values of X = 2 and X = 4 to find the total difference, then divide by the difference between X=2 and X =4
When X = 2 Y = 9
When X = 4 Y = 64
Difference between the two Y values = 64 -9 = 55
Difference between the two X values = 4-2 = 2
The rate of change = difference in Y divided by difference in X:
55/2 = 27.5

The pie chart represents the proportion of how Colin spent the £900 he took on holiday all values are in degrees workout how much he spent on each category
Answer:
£180,£540 and £180
Step-by-step explanation:
Looking at the information presented, we don't have the percentages given neither do we have the items bought
However, let's say the money was spent on drinks, hotel reservations and food.
20% on food
60% on hotel reservations and
20% on transportation
We can now compute the individual cost of the a amount spent on each category from their percentage
For food
=20/100*900
=0.2*900
=180
Hotel reservations
=60/100*900
=0.6*900
=540
Foe transportation
=20/100*900
=0.2*900
=180
So, if you have your data, only follow the steps above and you will get your answers
To check, when we add all the amounts together they should sum up to 900
180+540+180=900

Answer:
m∠7 = 63 degrees
m∠8 = 117 degrees
m∠9 = 63 degrees
Step-by-step explanation:
When two lines intersect at a point, then they formed 2 pairs of vertically opposite angles and 4 pairs of linear angles
The vertically opposite angles are equal in measuresThe linear angles have a sum of 180°In the given figure
∵ There are two lines intersected at a point
∴ The angle of measure 117° and ∠8 are vertically opposite angles
∴ ∠7 and ∠9 are vertically opposite angles
∴ The angle of measure 117° and ∠7 are linear angles
∵ The vertically opposite angles are equal in measures
∴ The angle of measure 117° and ∠8 are equal in measures
∴ m∠8 = 117°
∵ The sum of the measures of the linear angles is 180°
∴ m∠7 + 117° = 180°
→ Subtract 118 from both sides
∵ m∠7 + 117 - 117 = 180 - 117
∴ m∠7 = 63°
∵ m∠7 = m∠9 ⇒ proved up
∴ m∠9 = 63°

Given:
Two triangles are given in the figure.
To find:
The m∠K and m∠J.
Solution:
In triangle FHK and IGJ,
[tex]m\angle F=m\angle I[/tex] [Given]
[tex]m\angle H=m\angle G[/tex] [Given]
Two corresponding angles are equal. So,
[tex]\Delta FHK\sim \Delta IGJ[/tex] [By AA similarity theorem]
All corresponding angles of similar figures are same.
[tex]m\angle K=m\angle J[/tex] ...(i)
[tex]4y^2=6y^2-40[/tex]
[tex]4y^2-6y^2=-40[/tex]
[tex]-2y^2=-40[/tex]
Divide both sides by -2.
[tex]y^2=20[/tex] ...(ii)
Taking square root on both sides.
[tex]y=\pm \sqrt{20}[/tex]
Now,
[tex]m\angle K=(4y^2)^\circ[/tex]
[tex]m\angle K=[4(20)]^\circ[/tex] [Using (ii)]
[tex]m\angle K=80^\circ[/tex]
[tex]m\angle K=m\angle J=80^\circ[/tex] [Using (i)]
Therefore, the m∠K is 80° and m∠J is 80°.
Howard is putting napkins on tables at a restaurant. Each table gets the same number of napkins.
• After putting napkins on 6 tables, Howard has 124 napkins remaining
• After putting napkins on 10 tables, Howard has 108 napkins remaining
How many napkins does each table get ?
Answer:
Each table gets 4 napkins
Step-by-step explanation:
Rate of change
It usually refers to how fast one quantity changes with respect to another. We are given the following information.
After putting napkins on 6 tables, Howard has 124 napkins remaining
After putting napkins on 10 tables, Howard has 108 napkins remaining
This means that Howard used 124-108=16 napkins in 10-6=4 tables.
The rate of change (or rate of use in this case) is 16 napkins/4 tables= 4 napkins per table.
Each table gets 4 napkins
I need help, please. PLEASE, I NEED IT FAST.
Answer:
Hint: x is a negative number.
Step-by-step explanation:
The equation is x + 12 = -6 and you are trying to find x. The easiest way to solve this equation is by first subtracting 12 from both sides. It would look like x + 12 - 12 = -6 - 12. Since positive 12 and negative 12 are opposite and equal, they cancel each other out. This can be drawn as well into circles and crossed out for every positive circle with a negative circle. As for -6 and -12, you can use the same method of drawing circles, (trust me they can be very helpful, especially for people like me who need to see it visually before getting a hang of it). Since both are negatives, you would have to add them together and that would give you x.

The equation of the line in the given graph, in slope-intercept form, is determined as: y = 1/2x + 4.
What is the Equation of a Line?In slope-intercept form, we can express the equation of a line as, y = mx + b, where, m is the slope and b is the y-intercept of the graph.
Slope of the line (m) = change in y /change in x = 1/2
Y-intercept (b) = 4
Substitute m = 1/2 and b = 4 into y = mx + b:
y = 1/2x + 4
The equation of the line is: y = 1/2x + 4.
