Fifteen more than twice the hours Carla worked last week is the same as three times the hours she worked this week decreased by
lapo4ka [179]
2x-15=3(x-15) 
2x-15=3x-45
2x+30=3x
30=x

Let's check this work!

2(30)-15=3(30-15)
60-15=3(15)
45=45

She worked 45 hours each week

 *the reason it is 2x-15 and not 15+2x is because "more than" is considered a "turn around word" meaning it is the opposite

8k - 11 = 8k - 11

So, these two equations equal to the same thing.

Rapunzel sees a flying saucer. The radius of the flying saucer is 18 feet. What is the area of the flying saucer using 3.14 roun
Vladimir79 [104]

Answer:

1017.4ft^{2}

Step-by-step explanation:

Area of a circle = \pi r^{2}

However, the question wants to use 3.14 instead of \pi.

Since the radius is given, which is 18 feet, we can plug and chug.

A = 3.14*(18ft)^{2} \\A = 3.14*324ft^{2}\\A = 1017.36ft^{2}

However, the question wants us to round it to the nearest tenth.

Therefore, the answer is 1017.4ft^{2}
