Answer:
If AB and CD are perpendicular, (slope of AB) x (slope of CD) = -1
9/a = -1
a = -9
Answer:
See below.
Step-by-step explanation:
1.
3x + 7 + 10x + 17 = 180 ( property of inside angles of 2 parallel lines)
13x + 24 = 180
13x = 180 - 24 = 156
c = 156/13
x = 12.
2.
As the triangle is a right triangle:
42.7 + N = 90
N = 90 - 42.7
= 47.3. degrees.
Answer:
Paul should be wearing a light jacket appropriate for about 59 F or 15 °C
Step-by-step explanation:
If it is 4:00 a.m. in Honolulu when it is 2:00 p.m. in London, then the difference between times is:

London is 10 hours ahead of Honolulu.
If Paul left Honolulu at 12:00 p.m, the corresponding time in London was:

Since he arrived in London at 1:00 p.m. at Friday, the flight time was:

The flight took 15 hours in total. If the temperature was 30°C when he boarded the flight and it decreases at a rate of 1°C per hour, the temperature when Paul arrives in London is:

Converting it to Fahrenheit

Paul should be wearing a light jacket appropriate for about 59 F or 15 °C
Answer:
0
Step-by-step explanation:
because it has no slope
$12 each. $75 - $39 = $36. $36 divided by 3 = $12. Assuming he used all his money.
