kolbaska11 [484]

Answer:

10017

Step-by-step explanation:

10^(4)-\sqrt(121)+3^(3)+4^(0)

So, 3^3= 27

4^0=1

10^4=10,000

-square 121= -11

A boat can travel 23mph in still water. If it travels 248 miles with the current in the same length of time it travels 120 miles
mixas84 [53]

Answer: the speed of the current is 8 mph.

Step-by-step explanation:

Let represent the speed of the current

boat can travel 23mph in still water. This means that the total speed with which the boat travelled is (23 + x) mph.

Time = distance/speed

If it travels 248 miles with the current, it means that the time it took the boat to travel with the current is

248/(23 + x)

in the same length of time it travels 120 miles against the current. This means that the total speed with which the boat travelled is (23 - x) mph. The time it took the boat to travel against the current is

120/(23 - x)

Since the time is the same, it means that

248/(23 + x) = 120/(23 - x)

Cross multiplying, it becomes

248(23 - x) = 120(23 + x)

5704 - 248x = 2760 + 120x

120x + 248x = 5704 - 2760

368x = 2944

x = 2944/368

x = 8 mph

Jocelyn Angelica bought a dress marked, "Sale Price is 18% Off." The cashier told her she saved $23. How much was the price of t
agasfer [191]

Answer:

$28.05

Step-by-step explanation:

Since the sale price is 18% off, this means we pay 100-18 = 82% of the original price.  82% = 82/100 = 0.82; using x as the original price, we can set up the equation

0.82x = 23

Divide both sides by 0.82:

0.82x/0.82 = 23/0.82

x = 28.05
