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:
She was driving for 5 hours
Step-by-step explanation:
Let us solve the question
∵ Kate begins with 16 gallons of gas in her car
∵ Her car burns 3 gallons of gas each hour
→ That means the rate of burn of the gas is 3 gallons per hour
∵ She ends her road trip with 1 gallon of gas left in the tank
→ That means she used the difference between 16 and 1 gallons
∴ The number of gallons she used = 16 - 1 = 15 gallons
→ By using the ratio method
→ Gallon : hour
→ 3 : 1
→ 15 : x
→ By using cross multiplication
∵ 3 × x = 15 × 1
∴ 3x = 15
→ Divide both sides by 3
∴ x = 5
∵ x represents the number of hours of her trip
∴ She was driving for 5 hours
Answer:
6.6368
Step-by-step explanation:
20m per second, because the difference between -50 and 250 is 300, and just divide 300 by 15, because distance/speed.
