Answer: 1/5
Step-by-step explanation:50%50=1
100%50=0.5
1) Formula: area = height * base / 2
2) Call x the height:
height = x
base = 2x
3) State the equation:
(x)(2x) = 49 in^2
4) Solve the equation:
2x^2 = 49 in^s
x^2 = (49/2) in^2
x = √(49/2) in
x = 7√2 / 2 in = 3.5 √2 in
5) Solution:
height = 3.5 √2 in and base = 7√2 in
6) Verification: area = (7√2 in) (3.5√2 in) = 49 in^2
Answer: height = 3.5√2 in and base = 7√2 in.
Notice that

so that

We have


so that

You might already know that



so from these formulas we get



If you don't know the formulas mentioned above:
- The first one should be obvious; if you add
copies of 1 together, you end up with
. - The second one is easily derived: If
, then
, so that
or
. - The third can be derived using a similar strategy to the one used here. Consider the expression
, and so on.

The interval from $9 to $10 contains the largest number of sandwich prices. Option B
<h3>Which is a correct statement regarding sandwich prices, based on the histogram?</h3>
Generally, A graph known as a histogram displays the frequency of occurrence of numerical data via the use of rectangles. The frequency of a variable's distribution is shown by its position along the vertical axis, which is the height of a rectangle (the amount, or how often that variable appears).
In conclusion, The greatest number of sandwich costs may be found in the range from $9 to $10. Alternative B
