True, because of the Triangle Inequality Theorem.

To test if you could construct a triangle, make sure the following inequalities are true.

9 + 4 > 11

9 + 11 > 4

4 + 11 > 9.

These 3 lines form a Scalene Triangle, which is a triangle with 3 sides of 3 different lengths. According to the Triangle Inequality Theorem, a triangle results, because, the longest sides (11) is less than the sum of the other two sides ( 9 + 4) = 13. 9 + 11 > 4, 4 + 11 > 9, 4 + 9 > 11

Therefore, your answer would be, TRUE, because, of the Triangle Inequality Theorem.

Elena went to the store where you can scoop your own popcorn and buy as much as you want.she brought 10 ounces of spicy popcorn

kifflom [539]

Answer:

A. 4 ounces

Step-by-step explanation:

Given that Elana paid $2.50 for 10 ounces of popcorn, let x be the amount popcorn a dollar will buy.

Thus we have:

$2.50 = 10 ounces

$1 = x

Cross multiply

$2.50 × x = 10 ounces × $1

Divide both sides by $2.50

($2.50 × x)/$2.50 = (10 ounces × $1)/$2.50

x = (10 ounces)/2.50

x = 4 ounces

Therefore, you can buy 4 ounces of popcorn per dollar

The equation for a circle is x^2 - 8x + y^2 -8 =0. what is the equation of the circle in standard form?

yKpoI14uk [10]

You have to complete the square on this to get it into standard form of a circle. Move the 8 over to the other side because that's part of the radius. Group together the x terms, take half the linear term which is 8, square it and add it in to both sides. Half of 8 is 4, 4 squared is 16, so add in 16 to both sides. I'll show you in a sec. You don't need to do anything to the y squared term. This just means that the center of the circle does not move up or down, only side to side, right or left. Here's your completing the square before we simplify it down to its perfect square binomial. $( x^{2} -8x+16)+ y^{2} =8+16$ . Now break down the parenthesis into the perfect square binomial and do the addition of the right: $(x-4) ^{2} + y^{2}=24$ . This is the standard form of a circle that has a center of (4, 0) and a radius of $\sqrt{24}$
