Answer:
The table of values and their graph show above a straight line that passes through the origin. This indicates that the relationship between the two currencies is in direct proportion. Think about what this means in real terms – if you have ten times more dollars than another person, when you both exchange your money, you will still have ten times more money. Notice also that the graph passes through the origin; this makes sense as if you have no dollars you will get no pounds!
We can express these relationships algebraically as well as graphically.
Hey there!
The first thing we can do is find the number of third in 4.
We can do this by multiplying 4 by 3 since there are 3 thirds in a whole.
4 x 3 = 12
So, 4 = 12/3
If she studies for 2/3 an hour each night, then we can divide 12 by 2 to figure out how many 2/3 go into 12/3.
12 ÷ 2 = 6
So, she studied for 6 days.
Hope this helps!
Answer:
(0,-9)
Step-by-step explanation:
Well first we need to solve the rowing eqation by combining like terms and separating x.
So let’s do -3x
-9 = x -9
+9
x = 0.
So if x is 0 we can plug that in one of the equations.
y = 4(0) - 9
y = -9
So the solution where the 2 lines meet is at (0,-9)
For more proof look at the image below.
63.62
Area=3.14(radius^2) to get radius divide diameter by 2
6 cm = 30m
find out how much meters 1 cm is equal too. Divide 6 from both sides
6cm/6 = 30,=m/6
cm = 30/6
cm = 5m
So for every centimeter, it equals 5 meters
You have 15 centimeter, so multiply 5 to it
15 x 5 = 75
75 meters is your final answer
hope this helps
