Answer:
Part 1)
Part 2)
Step-by-step explanation:
Part 1) Find the measure of angle OAD
we know that
OA=OD=radius of the circle
If line AD≅ line AO
then
The triangle AOD is an equilateral triangle
Remember that
An equilateral triangle has the three equal sides and the three internal angles equal (60 degrees each one)
so
Part 2) Find the measure of angle DBA
we know that
The inscribed angle measures half that of the arc comprising
so
----> by central angle
substitute the value
Cost of 25 pound flour is $30.75.
What is Multiplication?
To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
Price of 3 pound flour = $3.69
She needs 25 pounds of flour to make enough cookies for a bake sale.
Now, Price of 3 pound flour = $3.69
Hence, Cost of 1 pound flour = $3.69 ÷ 3 = $1.23
So, Cost of 25 pound flour = 25 x $1.23
= $30.75
Therefore, Cost of 25 pound flour is $30.75.
