Remember that a conditional statement (
p→q) is an if-then in which the first part,
p, is the hypothesis and the second part,
q, is the conclusion.
1. Here the set
m<span>
∠A=40° is a subset of the set
Acute Angles, so </span>
m∠A=40° is the hypothesis and
Acute Angles is the conclusion.
In other words:
m∠A=40°→∠A is an Acute Angle
if m∠A=40°,
then ∠A is an Acute Angle
We can conclude that the conditional statement that describes the Venn diagram is:
if m∠A=40°, then ∠A is an Acute Angle2. Just like before, the set

is a subset of the set

; therefore,

is the hypothesis and

is the conclusion.
In other words:

→
if 
,
then 
We can conclude that the conditional statement that describes the Venn diagram is:
if 
,
then
Answer:
4
Step-by-step explanation:
Let's say B is the number of boys and T is the number of teachers.
T / (B + 18) = 2/21
B/18 = 4/3
Solve the second equation for B.
B = 24
Plug into the first equation to find T.
T / (24 + 18) = 2/21
T = 4
Remember, the volume formula of a sphere is

.
Set that equation equal to whatever volume they give you and solve for r.

=

Now solve for r! I know you can do this. If you need help, just comment.
12 + 36 = 48
your answer is 48 inch
hope this helps
