Lucy went to buy apples, she bought the first two for the full price and the last one for half the price. Is the relationship between the number of apples and the cost proportional? Justify an answer

Answers

Answer 1
No it is not proportional. Since she brought the last apple for 1/2 the price, the equation won’t be linear (straight line) anymore so it won’t be proportional. Proportional means the same unit rate.

11) Is the following biconditional true? Explain. Two people are brother and sister if-and-only-if they are siblings.​

Answers

Answer:

Well, not exactly.

Step-by-step explanation: You see, there's this thing called half siblings. They aren't exactly quite any different to normal siblings, except the fact that they either have the same mother and different father, or the same father and different mother. This usually results after a mother and a father divorce, or their respected love one dies, and they have children. The mother/father then can remarry, and when their wife/husband also has a child. The two or more children become half siblings. Also, if we're gonna talk not literal siblings. Close friends often like to think of each other as siblings, though they aren't biologically siblings. Half siblings and step sisters are two different things, half is where your sibling shares half your genes, and step siblings are where they don't have any of your genes and only their respected parent's genes. Now depending on if they mean biologically siblings, I would say true. But if they count all, then it would be false.

[tex]n=\frac{386x-75}{5}[/tex]

Step-by-step explanation:

Add like terms

[tex]-35x+3\cdot \frac{3}{5}x-22\cdot \:2x-15=n[/tex]

Add 15 on both sides

[tex]-35x+\frac{9}{5}x-44x-15+15=n+15[/tex]

Simplify

[tex]-35x+\frac{9}{5}x-44x=n+15[/tex]

Multiply sides by 5

[tex]-35x\cdot \:5+\frac{9}{5}x\cdot \:5-44x\cdot \:5=n\cdot \:5+15\cdot \:5[/tex]

Simplify

[tex]-386x=5n+75[/tex]

Divide both sides

[tex]\frac{-386x}{-386}=\frac{5n}{-386}+\frac{75}{-386}[/tex]

You will get

[tex]x=-\frac{5n+75}{386}[/tex]

Then you will solve for n using x

Multiply both sides by 386

[tex]\frac{386\left(5n+75\right)}{386}=386x[/tex]

Simplify

[tex]5n+75=386x[/tex]

Subtraction

[tex]5n+75-75=386x-75[/tex]

Simplify

[tex]5n=386x-75[/tex]

Divide by 5 to get n

[tex]\frac{5n}{5}=\frac{386x}{5}-\frac{75}{5}[/tex]

[tex]n=\frac{386x-75}{5}[/tex]

You didn't really specify, but I'm going to assume you meant as simplified as possible. If you write it as a fraction, it will be ½ or as a decimal it will be 0.5.

Answer:

1:2

Step-by-step explanation:

Simplifying a ratio is like simplifying a fraction.

Simply put the number to the left as the numerator, and the number to the right as the denominator.

In this case, 3/6 = 1/2.

Hence, plug the numbers right back in and you get 1:2.

Let the length of the pole to be : x m

1/5 of x is inside the mud, this will be : 1/5 x

2/3 of x in inside water , this will be : 2/3 x

10 m remaining is above the water surface. Finding the fraction that remains will follow;

In words, this is seventeen eighteenths

==========================================

Work Shown:

4/9 + 9/18

8/18 + 9/18 ... see note below

(8+9)/18

17/18

----------------

note: To go from 4/9 to 8/18, we multiply top and bottom by 2. So that's why 4/9 = 8/18.

The diagram below shows a visual representation of why 4/9 = 8/18.

In the top row, I've drawn out 9 rectangles of the same size. Then I've shaded 4 of the 9 rectangles to represent the fraction 4/9. In the bottom row, I've cut each of those 9 rectangles into two smaller equal pieces, so we have 9*2 = 18 rectangles now. Note how the shaded regions are the same size, so this shows 4 green regions doubles to 2*4 = 8 yellow regions; therefore 4/9 is the same as 8/18.

Answer: its 17/18
