Answer:
a)
b) SSA does not constitute a proof. You need another fact.
Step-by-step explanation:
You should actually show congruency first
Angles opposite = sides are themselves equal.
<C = 50o
<J = 50o
But there is nothing that says x is 1/2 of <JAC
So it's unsolvable
Part B also has the same conclusion.
Answer:
$91.75
Step-by-step explanation:
She earns $2.15 an hour and worked 20 hours this week so
20 × 2.15 = 43 and she earned 15% tip off the meals she served
to calculate how much 15% of 325 does we multiply 325 with 15 and divide it with 100
325 × 15 ÷ 100 = 48.75
48.75 + 43 = 91.75
Answer:
210 mph
Step-by-step explanation:
speed of jet = x
headwind: speed = x - 27
time taken = 1134.6/(x - 27)
tailwind: speed = x + 27
time taken = 1469.4/(x + 27)
same amount of time:
1134.6/(x - 27) = 1469.4/(x + 27)
Cross multiply,
1134.6(x + 27) = 1469.4(x - 27)
1134.6x + 30634.2 = 1469.4x - 39673.8
334.8x = 70308
x = 210 mph
2.8 mi
3.3mi
4.8+7(3)=8+21=29mi
5.yes, she hikes continuously so distance can be fractional parts of a mile
7.y=12x+120, y=12(5)+120=180
8.y=6.5x+10,6.5(10)+10=75
