Answer:

Step-by-step explanation:

480 divided by 6 is 80, so she was initially traveling at 80 mph.

She then increased her speed by 20 mph, therefore making it 100 mph. (Someone arrest her already.)

560 divided by 100 is 5.6 hours.

0.1 of an hour is 6 minutes.

0.6 of an hour is therefore 36 minutes.

Your answer is 5 hours and 36 minutes.

Please help!!!
Effectus [21]

Answer:

a + b + c + d + e = 180.

Step-by-step explanation:

We can prove that a = angle CBA (vertically opposite angles are equal).

Now, since lines DE and CA are parallel, then it follows that c = angle ACE (alternate angles are equal). Similarly, b = angle CAD.

But notice that what we've just done is found the angles of the triangle CBA.

So the sum of the angles (a + b + c + d + e) is the sum of the angles of a triangle.

We then conclude that a + b + c + d + e = 180 degrees.

a computer costs 400 dollars. Its 20 percent off with an additional 5 percent off, there's no sales tax. How much does the compu
zhenek [66]

The computer costs $304 now.

Step-by-step explanation:

Given,

Cost of computer = $400

First discount = 20%

Amount of discount = 20% of $400

Amount of discount = \frac{20}{100}*400=\frac{8000}{100}

Amount of discount = $80

Price after first discount = 400-80 = $320

Additional discount = 5%

Amount of additional discount = 5% of price after first discount

Amount of additional discount = \frac{5}{100}*320=\frac{1600}{100}

Amount of additional discount = $16

Final cost = 320-16 = $304

The computer costs $304 now.
