A. 26 7/12
B. 30 7/12
C. 42 1/12
D. 43 1/12
The solution is, the original roll of paper was 43 1/12 in. long.
the correct option is, D. 43 1/12.
Addition is a way of combining things and counting them together as one large group. ... Addition in math is a process of combining two or more numbers.
here, we have,
given that,
Sami cut 6 3/4 inches off a long roll of paper.
If the roll is now 36 1/3 inches long,
i.e. cut paper = 27/4 in.
remaining paper = 109/3 in.
so, we get,
total paper = 27/4 + 109/3
= 27*3 + 109*4 / 12
=517/12
=43 1/12
Hence, The solution is, the original roll of paper was 43 1/12 in. long.
the correct option is, D. 43 1/12.

The diver's change in elevation in each interval is, 23
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
A diver descends from an elevation of 6 feet below sea level to an elevation of 98 feet below sea level in 4 equal intervals.
Hence, The diver's change in elevation in each interval is,
⇒ (98 - 6) / 4
⇒ 92 / 4
⇒ 23
Thus, The diver's change in elevation in each interval is, 23

If 1 ml of volume contains 1 mg of epinephrine, then 0.1 ml of volume contains 0.1 mg of epinephrine.
Let x be the number of ml you need.
Ratio: 1 ml is to 1 mg as x ml is to 0.1 mg
(1 ml)/(1 mg) = (x ml)/(0.1 mg)
Cross multiply.
1 * x = 1 * 0.1
x = 0.1
Answer: 0.1 ml
