Answer:
Step-by-step explanation:
d=2q, q=d/2
10d+25q=630, using q=d/2
10d+25d/2=630
20d+25d=1260
45d=1260
d=28
So he has 28 dimes.
Answer:
Choice C.
Step-by-step explanation:
3rd degree means that the expression must have power of 3 as the highest power.
So, choice b is wrong since it has highest power of 8. All the other choices have highest power of 3.
Binomial means expression that has two terms.
So, choices d and a are wrong because they have 3 terms each.
So, choice C is correct answer and also it has constant as 8.

Answer:
(-1.92, 1.08)
Step-by-step explanation:
The <em>incenter</em> is the center of the largest circle that can be inscribed in the triangle. That circle is called the <em>incircle</em>. The incenter is at the point of intersection of the angle bisectors. For a right triangle, the <em>inradius</em> (the radius of the incircle), is found from a simple formula:
r = (a + b - c)/2 . . . . . where c is the hypotenuse, and a and b are the legs
In your triangle, the inradius is ...
r = (5 + 3 -√(5² +3²))/2 = 4 -√8.5 ≈ 1.08452
Among other things, this means the coordinates of the incenter are about (1.08, 1.08) from the right angle vertex, so are about ...
incenter ≈ (-1.92, 1.08)
Answer:
$60
Step-by-step explanation:
11 identical pairs of Air Jordan cost $660.
To find the cost of one pair, you have simply to divide the total amount paid by the total number of pairs.
Total amount paid = $660
Total number of pairs = 11
The cost of one pair
