Answer:
a = - 27
Step-by-step explanation:
- 
a - 6 = 12 ( add 6 to both sides )
- a = 18 ( multiply both sides by 3 to clear the fraction )
- 2a = 54 ( divide both sides by - 2 )
a = - 27
Answer is 71.3
31*2.3=71.3
If a function is undefined, this usually means that the
value is 1 / 0.
Since tan theta is the reciprocal of cot theta.
Therefore:
cot theta = 1 / 0 = 1 / tan theta
Taking the right side:
1 / 0 = 1 / tan theta
Rearranging so that tan theta is in the numerator:
tan theta = 0
Answer:
Step-by-step explanation:
If you subtract the extra 12 quarters from the total, you have $4.55 that can be made up of groups of 1 quarter and 1 dime. Since those groups are worth $0.35, there are $4.55/$0.35 = 13 of them.
There are 13 dimes and 13+12 = 25 quarters in the purse.
<span>A length is constructible if it can be obtained from a nite number of applications of a compass and straightedge. A constructible number is a constructible length or the negative of a constructible length. The demonstrations in this section, elsewhere in the text, and in class emphasize three part of the problem solving process for constructions:
1. Investigation or analysis. The usual approach is to imagine the problem is solved and search for relationships or properties that will allow us to accomplish the construction.
2. Construction. We propose the steps in the construction and perform the construction.
3. Proof: We justify that the constructions steps are valid and that the construction accomplishes what it was supposed to do.</span>
