Dividing by a fraction means the same as multiplying by its reciprocal.
In other words, change the division sign to multiplication
and flip or take the reciprocal of the second fraction.
So we can rewrite 2/13 ÷ 1/6 as 2/13 × 6/1.
Now multiply across the numerators and denominators to get 12/13.
Answer:
Step-by-step explanation:
KCF = Keep Change Flip
2/3 divided by 1/6
K C F
2/3 you keep
divided you change it to Multiplication X
And Flip 1/6 to 6/1
then Multiply
2/3 x 6/1 =
12/3 = 4
The table shows the number of windows and the number of panes of glass in the windows. Jim predicts
that for 15 windows there are 75 panes. Is Jim correct? Use the ratio of windows to panes to explain if
Jim's prediction is correct or incorrect.
Windows
Panes
2.
12
3 4
18 24
5
30
The ratio of panes to windows is the same for all data in the table. The ratio of panes to windows is
panes
12
To find how many panes there are if there are 15 windows, multiply the ratio
windows 2.
of panes to windows by 15. The number of panes there are if there are 15 windows is . Since
Jim's prediction was 75 panes for 15 windows then his prediction was (select)
Answer:
no his prediction is not correct. there would be 90 window panes
Step-by-step explanation:
12 panes in 2 windows so 1 window has 6 panes. multiply the 15 windows by 6 panes to get the total of 90 panes
12/2=6
6x15=90

6√3
Step-by-step explanation:
6 is x. side across from right angle (12) is 2x. so 6x2 to get 12. missing side is x√3. so 6√3
Answer:
6√3
Step-by-step explanation:
using the pythagorean theorem you can plug in the numbers to get √(12^2 - 6^2) = √(144-36) = √108 = 6√3.
6. Mary flips the coin and then she spins the spinner. What is the
probability that the coin will not land on tails, and the spinner will not land
on 3? Spinner (1, 2, 3, 4); Coin (H, T) *
A 1/8
B 1/4
C 3/8
D 1/2
Answer: For the coin, there are 2 possibilities which are Heads and Tails so the possibility is 1/2 and for the spinner it will be 1/4 because there are 4 possibilities.

Is Figure A congruent to Figure B? Explain.
No, because the orientation of Figure B is not the same as Figure A.
Yes, because Figure B can be obtained from Figure A by a series of translations.
Yes, because Figure B can be obtained from Figure A by a rotation and a translation.
No, because there is no sequence of translations, rotations, and reflections by which Figure B can be obtained from Figure A.

negitive 17plus n over 5 =33 what is n
Answer:
250
Step-by-step explanation:
-17+n/5=33
n/5=33-(-17)
n/5=33+17
n/5=50
n=50*5
n=250
n=182
Step by Step Explanation:
The equation we would start out with is:
[tex] \frac{ - 17 + n}{5} = 33[/tex]
From here, we need to multiply both sides by 5. This would create an equation of -17+n=165, as we canceled out the 5.
Then, you need to add 17 to both sides to isolate the variable. This would make the equation n=182, our final answer.

The graph of y = f(x) is shown.
a) Find f(0)
4-
3.
b) Give the roots of f(x) = 0
Answer:
f(0) = 2
Roots are;
-2 and -1
Step-by-step explanation:
F(0) simply refers to the y-values when x = 0
This is the point at which the graph crosses the y-axis
the value here is 2
To
find the roots of f(x) , we simply find the points at which the plot crosses the x-axis
we have this at x = -2 and x = -1
These are what represents the roots of the equation
Stefan's city took a survey about a plan for a new park. Of the people surveyed, 2,800 liked the plan for the park and 1,200 did not. What percentage of the people surveyed liked the plan?
Answer:
70% of people surveyed liked the plan.
Step-by-step explanation:
Given that,
No. of people that liked the plan = 2,800
No. of people that did not like the plan = 1,200
We need to find what percentage of the people surveyed liked the plan. It can be given by :
[tex]\%=\dfrac{2800}{2800+1200}\times 100\\\\=70\%[/tex]
So, 70% of people surveyed liked the plan.

y = -4x + 1
11y = x + 146
Step 2: Solve for x
Substitution
Substitute in y: 11(-4x + 1) = x + 146Distribute 11: -44x + 11 = x + 146[Addition Property of Equality] Add 44x on both sides: 11 = 45x + 146[Subtraction Property of Equality] Subtract 146 on both sides: -135 = 45x[Division Property of Equality] Divide 45 on both sides: -3 = xRewrite/Rearrange: x = -3Step 3: Solve for y
Define original equation: y = -4x + 1Substitute in x: y = -4(-3) + 1Multiply: y = 12 + 1Add: y = 13At a sleepover, three friends ate of a pizza for a

3 × (c2 − 8) for c = 3
Answer:
I am assuming c2, is c^2.
3 × (c2 − 8)
=3 ×(3^2-8)
=27-8
=19
If c2 is c*2
Then,
3 × (c2 − 8)
=3×(6-8)
=18-24
=(-6)

How do i find a scale factor?
Answer:
In two similar geometric figures, the scale factor is the ratio of their corresponding sides, dividing the two corresponding lengths of the sides will gives the ratio, for example
What is the scale factor between 4 cm and 10 cm ?
4 and 10 are divisible by 2
Length A : 4 ÷ 2 = 2
Length B : 10 ÷ 2 = 5
so the scale factor from A to B is 2:5
