Answer:
The difference in price per ounce of the boxes is $0.03 or 3 cents.
Step-by-step explanation:
Divide each dollar amount by the ounces. The answer to $2.94 divided by 14 is 21 cents. $3.60 divided by 20 is 18 cents. Subtract 18 cents from 21 cents to get 3 cents.
Reduce each ratio to its minimum expression to find if they are equal.
35:28
10:8
Since both ratios reduce to 5:4, they are equivalent.
Another way to check a:b is equivalent to c:d, is that a*d = b*c
In this case, this will be true if 35 times 8 is equal to 10 times 28:
Since both products are equal, then the ratios are equivalent.
Perpendicular lines have negative reciprocals. This means that if you multiply the slopes of both lines, the product will be a -1.
In your given point-slope equation, the slope is 1/3. Therefore, the negative reciprocal of 1/3 must be -3.
Out of the given options:
y + 2 = -3(x — 4)
y = -3x - 5
are the linear equations that are perpendicular to y — 1 = 1/3(x + 2).
Therefore, the correct answers are Options 1 and 3.

If b=2 and c=3, then
a= √(3²-2²) = √(9-4) = √5
If a=3 and c=6, then
b= √(6²-2²) = √(36-9) = √27 = 3√3
If a=4 and b=6, then
c= √(4²+6²) = √(16+36) = √52 = 2√13
We have a large numer and using scientfic notation is a great way to break down the number. So let's break it down!
1,000 x 1 = 1,000
3 x 100 = 300
6 x 10 = 60
3 x 1 = 3
So the form for scientific notation is a x 10b and we need to convert it into decial form.
1,360 becomes 1.36 (forget the 0) for a. 10 b is 103
1.36 x 103. Notation will always have a square. Our b.
10^3
SO, now we have
1.36 x 10^3 = 1,360
