Answer:
21. Line b.
22. Line a.
Step-by-step explanation:
Line b is the most steep because it goes up 5, the rest goes up only 1 and 3
Line a is the least steep because it only goes up 1, while the rest go up more
Answer:
Well, the correct answer is 119.<u>4347826086956521739130</u> (after the 130 the whole decimal is repeated.
Step-by-step explanation:
Although if your assignment is asking for an estimate you could probably just say 119 since the first and second decimal is less then 5
Answer:
4/10 or 2/5 chance of pulling an even card that is alos divisible by 60.
Step-by-step explanation:
Answer:
11.4
Step-by-step explanation:
b/sinB = a/sinA
b/sin(42) = 17/sin(88)
b = 11.38215401
First problem: draw a line segment through the vertex R and a point C on PQ such that the segment is perpendicular to PQ, thus forming an altitude of the triangle. This new segment CR, the new segment CP, and PR form a 30-60-90 right triangle, where the measure of angle PCR is 90 degrees. CR then occurs with PR in a ratio of
to 2, so
and this can be considered the height of a triangle whose base is PQ. The area is then
Second problem: the sum of the interior angles of any triangle is 180, so the measure of the missing angle must be 180 - 20 - 35 = 125 degrees. By the law of sines, the length of the missing side (call it
) satisfies
Use Heron's formula to find the area of the triangle:
where
is the area,
are the lengths of the sides, and
is the half the perimeter of the triangle. Then the area is about
square feet. Convert to square yards:
then round up to 7 square yards. At a price of $12.50 per square yard, the total price will be $87.50.
