Answer:

300

Step-by-step explanation:

The red portion is marked with a small square; that means it is a 90° section. It is 1/4 of the whole circle. They also said 75 kids chose red. If 1/4 of the circle represents 75 kids, then the whole entire circle would represent 75+75+75+75 kids or 4(75) kids, which is 300 kids.

How much medicine should he add to the food?​
quester [9]

Answer:

Paul should give 18 teaspoons of medicine to his dog.

Step-by-step explanation:

It is stated in the question that for every 12 pounds, 3 teaspoons of medicine is to be given to the dog.

This implies that:

12 pounds = 3 teaspoons

1 pound = 3/12 teaspoons

             = 1/4 teaspoons                      <em> ( by cross multiplication )</em>

<em />

<h3>72 pounds = 1/4 * 72 teaspoons</h3><h3>                   = 18 teaspoons</h3><h3 />

Hence, Paul should add 18 teaspoons of medicine to his dog's food.

How many times does the graph of 4x = 32 - x2 cross the x-axis?<br><br> 0<br><br> 1<br><br> 2
Yakvenalex [24]

Answer:

2

Step-by-step explanation:

4x = 32 - x2 would be much clearer if written as 4x = 32 - x^2.  Please use

" ^ " to indicate exponentiation.

Rewrite 4x = 32 - x^2 in the standard form of a quadratic:  x^2 + 4x - 32

Then the coefficients are a = 1, b = 4 and c = -32.

Find the discriminant.  It is b^2-4ac.  

Here, b^2-4ac = 4^2 - 4(1)(-32), or 16 + 128, or 144.

Because the discriminant is positive, we know immediately that this quadratic has two real, unequal roots.

So, the answer to this question is "the graph of 4x = 32 - x^2 cross the x-axis in two places."
