Answer:
x = 32
Step-by-step explanation:
Using the Secant and Tangent Intersection Theorem we can say;
(x + 18) (18) = 30²
18x + 324 = 900
18x = 576
x = 32

Answer:
- multiplying a multi-digit number by itself several times (finding the power of a number)
- finding a square root
- statistical calculations
Step-by-step explanation:
We don't know what your introduction tells you, but the above-listed operations are ones I choose to use a calculator for. I also use a calculator for ordinary arithmetic, such as division by numbers with 2 digits or more. (It is simply faster and requires no scratch paper.)
If statistical calculations are not done with a calculator, they at least require the availability of suitable tables.
___
All of these operations can be done by hand without a calculator, and were in times passed. Lifetimes of effort were involved in generating some of the original math tables for statistics, trig, logarithms, and other functions readily evaluated using a modern calculator.
3 3/4 - 2 1/3
get a common denominator of 12
3 3/4 * 3/3 = 3 9/12
2 1/3 * 4/4 = 2 4/12
3 9/12 - 2 4/12=
1 5/12
Answer: they ate 1 5/12 pints
Answer:
