Answer: 4m
Step-by-step explanation:
Note : midpoints divide a line into two equal parts.
To calculate the length of SA;
We can consider the large triangle QRS with
Two midpoints :
A on the line QS, QA = 4m ;
and B on the line RS with RB = 3m
Fron the definition of midpoint :
QS = QA + AS
where QA = AS
QS = 2QA = 2AS
Therefore,
QA = QS
4m = 4m
Answer: 15.7 minutes
Step-by-step explanation:
Let x be the time in the beginning (in minutes).
Given: The track team is trying to reduce their time for a relay race.
First they reduce their time by 2.1 minutes.
Then they are able to reduce that time by 10
If their final time is 3.96 minutes, then
Hence, their beginning time was 15.7 minutes.
Answer:
= {2, 4, 10}
Step-by-step explanation:
A set is a collection of objects called elements. These element are refered to as members of the set.
Set A contains all integers from 1 to 10 inclusive;
A = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}
A subset of a given set implies that every element of the subset are also elements of the given set. Set B is a subset of A;
B = {1, 3, 5, 6, 7, 8, 9}
Complement of a given set refers to elements not in the general set. Set C is the complement of B;
= {2, 4, 10}
Answer:
The diameter of an extra large pizza from Gambino's Pizzeria is
Step-by-step explanation:
we know that
The area of a circle (circular pizza ) is equal to
we have
substitute in the formula and solve for the radius r
Simplify
Find the diameter
Remember that the diameter is two times the radius
