Answer:
Measure of Arc AC is 30 degrees
Step-by-step explanation:
To find the value of the marked arc, we are going to use the arc-angle relationship
from the type of given diagram, we can figure out the relationship to use
Mathematically, we have this as;
Measure of Arc AC = 2 * angle ABC
So we have arc AC as 2 * 15
Arc AC = 30 degrees
Answer:
the original number is 7
Step-by-step explanation:
7•4 = 28
28+12=40
<span>I believe this question is referring to purchasing a discount on a loan's interest rate by putting more towards closing costs. For mortgages, sometimes they will allow you to "buy" a smaller interest rate. For example:
Loan A has an interest rate of 4.5% and no closing costs.
Loan B has an interest rate of 4.375%, but has $1000 in closing costs.
Normally, Loan A would be the better choice if you plan on keeping the home short term, but Loan B would be more beneficial for keeping the loan long-term. I don't really care to spend the time that is necessary to come up with an actual scenario, but I hope that helps enough for you to understand the question</span>
For this case we convert the mixed numbers into fractions:

Rewriting the expression:

We simplify:

Thus, the simplified form is:
Answer:

Answer:
b. z = 4
Step-by-step explanation:
Multiply both sides of the equation by 1/10. This gives ...
(1/10)·10z = (1/10)·40
z = 4 simplified
_____
<em>Check</em>
Putting 4 where z is in the original equation should give us a true algebraic expresion. It does.
10·4 = 40 true
