Answer:

This isn't a right triangle

Step-by-step explanation:

To see if this is a right triangle we use Pythagorean Theorem

The formula is a^2+b^2=c^2

We place the numbers in the formula:

4^2+5^2=7^2

4^2=16

5^2=25

7^2=49

16+25+49

41=49

They are not equal which makes it not a right triangle.

Answer:

The triangle is not a right triangle

Step-by-step explanation:

The sum of the squares of the side lengths do not equal the square of the hypotenuse:

4^2+5^2=7^2

16+25=49

41=49

41 does not equal 49, so this confirms my answer is true

The Walnut Cove Ruritan Club sells hot dogs and drinks from a concession stand at the annual 4th of July parade. Carl bought 4 h
timofeeve [1]

Let, cost of 1 hot dog and 1 drink is x and y respectively.

Carl bought 4 hot dogs and 6 drinks and paid $23.80.

4x + 6y = 23.80  ....1)

Susan purchased 4 hot dogs and 2 drinks and was charged $15.40.

4x + 2y = 15.40  ....2)

Subtracting equation 2 by 1, we get :

(4x + 6y) - (4x + 2y) = 23.80 - 15.40

4y = 8.4

y = $2.1

4x + 6×2.1 = 23.80

4x = 23.80 - 12.2

4x = 11.6

x = 2.9

Therefore, the  cost of 1 hot dog and what is the cost of 1 drink is $2.9 and $2.1 respectively.

Hence, this is the required solution.

neonofarm [45]

Answer:

Harry put 5 movies on each shelf.

Step-by-step explanation:

The information provided is:

  • On 4 different days, he bought 2 movies.
  • On 2 other days, he bought 3 movies each day.
  • After that he sold 2 sets of 2 movies.
  • He divided the remaining into 2 groups to put onto his shelves.

So, first Harry bought 2 movies on four different days.

That is, a total of 8 movies.

Then, he bought 3 movies on two other days.

That is, a total of 6 movies.

So, in total Harry bought 14 movies.

Now, he sold 2 sets of 2 movies.

That is, he sold 4 movies.

He has 14 - 4 = 10 remaining movies with him.

It is provided that he divided remaining movies into 2 groups to put onto his shelves.

So, he put 10/2 = 5 movies on each shelf.
