Complementary angles are angles that sum up to 90 degrees. For instance, and A and B are complementary if A + B = 90.
According to the question, if two complementary angles have measures of s and t then:
Twice of 's' is expressed as
If t is less than twice s, this can be expressed as .... 2

The properties of multiplication and division are an easier way when making calculations.
Let's see an example for each one.
Mutiplication:
Suppose we are going to multiply:
It is easier to make the product using the distributive property:
Division:
Suppose we have the following division:
By properties of the division, we know that this division is not defined.
Therefore, when we see a division between 0, we know that the answer is that it is not defined.
Answer:
The rules of multiplication and division help to divide and multiply in a faster way.
15.00-5.00-2.00-2.00= $6.00
Answer:
"90% confidence" means there is a probabilty of 90% that the population mean (average compensation for the population of party clowns) lies within the confidence interval.
Step-by-step explanation:
The confidence interval is a range of values in which, according to the level of confidence that is calculated, is likely to include a parameter of the population. In this case, this parameter is the population mean compensation of party clowns.
The level of confidence is 90%, so there is 90% of confidence (or probability) that the population mean compensation for party clowns lie within $9394 and $9926.
None of the options below is correct.
Answer:
angles 4, 6 and 8
Step-by-step explanation:
Angles 2 and 4 are vertical angles therefore they are congruent
Angles 2 and 6 are corresponding angles therefore they are congruent
Angles 2 and 8 are alternate interior angles therefore they are congruent
