At a NBA, the ratio of the score of team A to the score of team B was 16:21. If team A got 80 points, how many points did team B

nikitadnepr [17]

Answer:

105 points

Step-by-step explanation:

Let's call the scores of Team A and B 16x and 21x respectively. Since 16x = 80, that means x = 5, making Team B's score 21 * 5 = 105.

if a motercycle is moving at a constant speed down the highway of 40 km/hr, how long would it the motorcycle to travel 10 km

ahrayia [7]

Answer:

15 minutes

Step-by-step explanation:

First, the motorcycle goes at a speed of 40 km/hr.

The question asks for how long it would take to travel 10 km.

Well, there are 60 minutes in an hour, since we will be translating into minutes.

Also, 10 km is 1/4 of 40 km, so it would make sense that the time length would be 1/4 of an hour as well.

1/4 of 60 minutes is 15 minutes. So it takes 15 minutes for the motorcycle to travel 10 km.

Now, if all this wordy stuff is too much to comprehend, you can also solve using proportional relationships.

$\frac{40km}{60min}=\frac{10km}{xmin}$

Now cross multiply:

$40km*xmin=10km*60min\\40x=600$

Divide both sides by 40:

$\frac{40x}{40}=\frac{600}{40}\\x=15$

Again, this shows that it wouls take 15 minutes for the motorcycle to travel 10 km.

All the items on the sale rack were 75 percent off their original price.

tresset_1 [31]

Answer:

112 $ is the original price

Step-by-step explanation:

$x \times 0.75 = 84 \\ x = 84 \div 0.75 \\ x = 112$

you have to think that the original price multiplied by 0.75 (also known as 75%) gave the result of what he saves i.e 84 $. So we put up an equation with the original price multiplied by 75% which equals the 84 $ he saved on buying that item on sale
