Mathematics
1 answer:
Usimov [2.4K]3 years ago

Answer:

C

Step-by-step explanation:

To solve this use the equation x^2 -15x - 50 = y given in the problem and the value y = 50. Substitute y = 50 then solve for x by factoring.

x^2 -15x - 50 = 50\\x^2 - 15x -100 = 0

Find two numbers which multiply to -100 and also add to -15. The numbers are -20 and 5.

So the factored form is (x-20)(x+5) = 0.

Set each factor equal to 0 and solve.

(x-20) = 0 so x = 20.

(x+5)=0 so x = -5.

This means the temperature is 20 degrees C or -5 degrees C. Only 20 is an option. The solutions is C.

35 teenagers were asked what takeaways they liked to eat.
STatiana [176]

The number of teenagers that liked Indian only is 11 students.

<h3>How to use Venn Diagrams?</h3>

Counting students who liked Chinese and pizza

There were 35 teenagers altogether.

  • 24 liked Chinese
  • 16 liked Indian
  • 10 liked pizza

Since all the students who liked pizza also liked Chinese, and no student liked all three, we can just think about the remaining 25 students.

Of these, 14 liked Chinese and 16 liked Indian.

Since each student liked at least one of these, and there are a total of 30 'likes', then 5 students must like both Indian and Chinese.

This leaves 11 students who liked Indian only.

Thus, we conclude that the number of teenagers that liked Indian only is 11 students.

Step-by-step explanation:

You use Pythagorean theorem which is x^2 +y^2=z^2 (^ this means to the power of) so you would get 55^2+33^2=z^2. solving this would get you z=64.1404708433 or 64.1
