Answer:
Sean has 4 bags left over!
Step-by-step explanation:
Sean has 10 pounds of birdseed, which he separates into smaller bags. The line plot shows the weights of 8 bags Sean made. Sean's Bags of Birdseed x XXXXCO - 2 1 3 1 5 8 Weight (pounds) 3 4 1 co How many pounds of birdseed does Sean have left after making the bags? Move numbers to the boxes to show the answer. If there is no whole number, put a 0 in the first box.
When you divide the top and bottom you get a decimal number. So you compare those. Or if you draw it out then you can see that 21/30 is bigger.
Question
The exchange rate at the post office is £1=€1.17 how many euros will you get for £280
Answer:
<h2>
327.6 €</h2>
Step-by-step explanation:
you can solve with an equation
1£ : 1.17€ = 280£ : x
1 : 1.17 = 280 : x
x = 1.17 * 280 : 1
x = 327.6
-------------------
check
1 : 1.17 = 280 : 327.6
0.85 = 0.85
the answer is good
------------------------------------
or you can simpy solve with a multiplication
280 * 1.17 = 327.6
<h3>
Answer: k = 0 or k = 3</h3>
Explanation:
If you have repeated x values, then you wont have a function. For example, the points (1,5) and (1,6) mean we don't have a function since the input x = 1 leads to multiple outputs y = 5 and y = 6 simultaneously. For a function to be possible, we must have any input lead to exactly one output only.
What we do is set the x coordinates (k^2 and 3k) equal to each other and solve for k
k^2 = 3k
k^2-3k = 0
k(k-3) = 0 .... factoring
k = 0 or k-3 = 0 .... zero product property
k = 0 or k = 3
If k = 0, then (k^2,5) becomes (0,5). Also, (3k,6) becomes (0,6). The two points (0,5) and (0,6) mean the graph fails the vertical line test.
Similarly, if k = 3, then (k^2,5) becomes (9,5) and (3k,6) = (9,6). Another vertical line test failure happens here to show we don't have a function.
