the train traveled at an average speed of 48 miles per hour for the first 2 hours and at 60 miles an hour for the next hours. What was the train's average speed for the 6-hour trip? ( Average speed equals total miles divided by total time.)

Answers

Answer 1
Answer:

Answer:  56 mph

Step-by-step explanation:

48 miles x 2 hours = 96 miles

60 miles x 4 hours =  240 miles

240 + 96 = 360 total miles

360 / 6 (hours) = 56 mph

A recipe for one batch of cookies uses 5 cups of flour and 2 teaspoons of vanilla. If you use 20 cups of flour how many cups of vanilla should i use

Answers

The cup of vanilla to be used to prepare a recipe for the 4 batches of cookies is 0.1667 cups of vanilla.

Given that:

  • 1 batch of the cookies = 5 cups of fours + 2 teaspoons of Vallina

If 20 cups of flours are used and we know a cookie require just 5 cups, then:

the number of cookies to be made from 20 cups of flours is:

  • = (20 cups of flours × number of cookies)/5 cups of flour
  • = 4 cookies

Since there are 4 cookies to be made, then the total number of teaspoons to be used for the 4 cookies is;

  • = 2 × 4 cookies
  • = 8 cookies

Thus, 20 cups of flour and 8 teaspoons of vanilla are required to make four batches of cookies.

But, we are to leave our answers in cups of vanilla. Let, the unknown number of cups of vanilla be (x)

  • In a cup, there are 48 teaspoons
  • In (x) cup now, there are 8 teaspoons.

1 × 8 = 48 × (x)

(x) = (1 ×8)/48

(x) = 8/48

(x) = 0.1667 cups of vanilla.

Therefore, we can conclude that the cups of vanilla to be used are 0.1667 cups.

The two longer sides of a triangle Measure 16 and 22 which of the following is a possible link of the shortest side

Answers

the two longer sides of a right angle triangle are 16 and 22
let 22 be the hypotenuse (the longest side)
use Pythagoras Therom a²+b²=c²
in this question c=22 and b=16
to find the shortest side
22²-16²=a²
484-256=a²
228=a²
a=√(228)
a= 15.1

The formula a2xb2=c2 will help with this problem.

The longest sides, so the longer one is c2. the next is either a2 or b2. 2, in this case, is an exponent, so we multiply the number by itself.

So, a2+(16x16)=(22x22)

16 times 16 is 256. 22 times 22 is 484.

a2+256=484. 484-256 will leave you a2. Then, 484-256=228. Since a2 is still squared, you need to find the square root of 228. (which is about 15.1)

So of your answer choices, if it is among them, choose 15.
