Answer:
Surface Area: 615.75
Volume: 1436.76
Step-by-step explanation:
The equation for the surface area of a sphere is 4*pi*r^2
Just do 4*3.14*7*7
The equation for the volume of a sphere is 4/3*pi*r^3
Just do 1.33*3.14*7*7*7
There are 17 members who are only in gymnastics, 7 who are only in chess, and 3 who are in both.
17+3+7=27
800-27=773
Answer: If a quadrilateral is a square, then it is a rectangle. (choice D.)
Step-by-step explanation:
The Law of Syllogism states that if the following two statements are true: If p , then q . If q , then r . Then we can derive a third true statement: If p , then r .
We can apply this rule in the conditional statements:
<em>If a quadrilateral is a square, (p) then it has four right angles. (q)</em>
<em>If a quadrilateral has four right angles, (q) then it is a rectangle. (r)</em>
Therefore:
<em>If a quadrilateral is a square, (p) then it is a rectangle. (r)</em>

Answers:
-3.5 < 5
|-3.5| < |5|
============================================
Explanation:
Any negative number is <u>always</u> smaller than any positive number. So that's why -3.5 is smaller than 5 and where -3.5 < 5 comes from. It might help to set up a vertical number line. Stuff on top is larger than stuff down below.
---------
The vertical bars represent absolute value. The result of |-3.5| is 3.5 because this is the distance from -3.5 to 0 on the number line. Likewise, |5| = 5.
So that's how we get to |-3.5| < |5| which is effectively saying -3.5 is closer to zero than 5 is to zero.
