Find the area of the semicircle need help asapp
Answers
Answer:
2 pi
Step-by-step explanation:
The radius is 2
The area of a circle is
A = pi r^2
We have 1/2 of a circle so
1/2 A = 1/2 pi r^2
=1/2 pi ( 2)^2
=1/2 pi *4
= 2 pi

Rounding up this number of people to nearest ten thousand.
9 has a 'ones' value
Going to the right from left:
Second last zero has a 'tens' value.
Third from last zero has a 'thousands' value
4 has 'ten thousands' value
Round up 4 and because it is less than five it converts to zero
This gives an answer of 830,000.

The factor of the equation is (4x – 3) and (3x – 1). Then the solution of the equation will be 3/4 and 1/3.
What is a factorization?
It is a method for dividing a polynomial into pieces that will be multiplied together. At this moment, the polynomial's value will be zero.
The equation is given below.
12x² − 13x + 3 = 0
Then the factor of the equation will be
12x² − 9x – 4x + 3 = 0
3x(4x – 3) – 1 (4x – 3) = 0
(4x – 3)(3x – 1) = 0
x = 3/4, 1/3

Hey!
Hope this helps...
~~~~~~~~~~~~~~~~~~~~~~
What wee need to do, is find what x equals...
12x^2 - 13x + 3 = 0
12x^2 - 13x = -3
12x^2 = 13x - 3
12x = 13 - 3
12x = 10
x = 0.75
Now we check...
12x^2 - 13x + 3 = 0
12(0.75)^2 - 13(0.75) + 3 = 0
12(0.5625) - 9.75 + 3 = 0
6.75 - 9.75 + 3 = 0
-3 + 3 = 0
0 = 0
Here you go!

pack-out rate. The blueberry harvester machine collects about
22,000 pounds of blueberries per day with a 90% pack-out rate.
The pack-out rate is the percentage of collected blueberries
that can be packaged to be sold, based on Florida Blue Farms'
quality standards.
Let h represent the number of days the hand pickers work and
m represent the number of days the harvester machine is used.
Which of the following algebraic expressions can be used to
estimate the amount of collected blueberries that are packed at
the Florida Blue Farms for fresh consumption this season?
A (0.95h+200)(0.90+22000)
B 0.95(200h)+0.90(22000m)
C 200.95h+22000.90m
D (200h+0.95)(22000m+0.90)
Answers
The farm uses two harvesting tools for packages that needs to be sold. So, we have to consider the rates of both harvest tools and the number of harvest by both tools. The algebraic expression is:
Given that
days of hand pickers word
days harvester machine is used
--- pounds of hand pickers
-- pounds of harvester
-- pack out rate of hand pickers
-- pack out rate of harvester
The expression to estimate the amount is calculated as:
--- i.e. pounds of hand picker * its pack out rate + pounds of harvester * its pack out rate
So, we have:
Express as decimal
Rewrite as:
Hence, option (b) is correct.

The (interior) angles of a triangle always add up to 180 degrees. To find the exterior angles of a triangle, subtract the interior triangle from 360 degrees.
The total degrees of any polygon is (n-2)×180 (n is the number of angles). 3-2 is 1 and 1 times 180 is 180. Therefore, the angles of a triangle always add up to 180 degrees.
