1 answer:
MAVERICK [17]3 years ago
3 0

Answer:

  x = 5.4

Step-by-step explanation:

The marked sides are the hypotenuse and the side adjacent to the marked angle. That suggests the appropriate trig function is the cosine:

  Cos = Adjacent/Hypotenuse

  cos(19°) = 5.1/x

  x = 5.1/cos(19°) . . . . . multiply by x/cos(19°)

  x ≈ 5.4

Solve –2k + 12 < 30 for k.
PIT_PIT [208]

Answer:

k > -9

Step-by-step explanation:

Subtract 12 from both sides as we want to isolate k-

30 - 12 = 18

-2k < 18

Divide both sides by -2

18/-2 = -9

k > -9

For the following compound interest problem, how much interest would you earn if you put $600 in the bank at 5.5% for 2.25 year.
s2008m [1.1K]

Answer:

$74.25

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 5.5%/100 = 0.055 per year,

then, solving our equation

I = 600 × 0.055 × 2.25 = 74.25

I = $ 74.25

The simple interest accumulated

on a principal of $ 600.00

at a rate of 5.5% per year

for 2.25 years is $ 74.25.

Micah is planning a road trip. He estimates that he will drive a total of of 8 1/4 hours. He wants to stop for gas after 1/3 of
tigry1 [53]

8.25 hours is our base number here. 1/3 of it is taken up when he stops at the gas station.

8.25, 4.125 is half of it, 2.75 is our answer for this,

8.25/3 gives you 2.75 due to 2.75 making it 5.5 when doubled and so on

so, the answer is 2 3/4 hours, D

enot [183]
P(Al hits bottle first time) = 1/3
P(Al misses the first shot but hits on his second shot) =  
P( Al misses and bill misses and Al hits) = 2/3 * 3/4 * 1/3 = 1/6

So required probability = 1/3 + 1/6 =  1/2
