how do i find the area of parts of circles?
Answer:
Explanation below
Step-by-step explanation:
The equation for the area of a circle is pir^2
To find the area of parts of a circle you would do as the following examples:
the area of half a circle is (1/2)(pir^2)
the area of a quarter of a circle is (1/4)(pir^2)
the area of a third of a circle is (1/3)(pir^2)
the area of a tenth of a circle is (1/10)(pir^2)

James has6 7/12 cups of flour. He uses 2 5/12 cups to bake some cakes. He uses another 2 8/12 cups to bake some cookies.
How many cups of flour does James have left? Someone please help me i need this asap! <3
Answer:
I believe the answer would be 3/2 or 1 1/2
Step-by-step explanation:
This is how I did it
6 7/12 - 2 5/12 = 4 1/6
Then,
4 1/6 - 2 8/12 = 1 1/2
In decimal form, it'll be 1.5

jack and his 3 friends each ate 3pops on Monday if they all at the same amount the rest of the week how many pops could they eat in 3 weeks??
Answer:
216pops.
Step-by-step explanation:
If Jack and his 3 friends(4people total) ate 3 pops on Monday and ate 3pops for the rest of the week, that'd be 12 pops 1 day, and 12x6 is 72 then you have to multiple 72 by 3 and you get 216pops in 3weeks
Determine if the given relation is function or not. Give its domain and
range.
{(1, 6), (2, 7), (3, 8), (4, 9)}
Answer:
YesStep-by-step explanation:
According to definition of the function, it should have one-to-one relation.
We can see all pairs are unique, no repeated ranges for same domain.
Yes, this is a function.
Given relationship
(1,6)(2,7)(3,8)(4,9)Domain:-
{1,2,3,4}Range:-
{6,7,8,9}As every domain has an unique range it's a function

Step-by-step explanation:
A function f is odd and f(x)=x^2 for all x>0. Sketch the graph of this function and then write the rule of this function as a single formula.
We will see that we have a piecewise function:
f(x) = x^2 for x > 0.f(x) = -x^2 for x ≤ 0.The graph can be seen at the end.
What is an odd function?
A function is odd when f(-x) = -f(x) for all the values of x in the domain of the function.
In this case, we know that:
f(x) = x^2 for x > 0.
Then, for the negative range, the sign must change (but the quadratic function is even). Then we define the function in the negative range as:
f(x) = -x^2 for x ≤ 0.
This is the odd function (a piecewise function) for the whole domain:
f(x) = x^2 for x > 0.f(x) = -x^2 for x ≤ 0.The graph of the piecewise function can be seen below.
If you want to learn more about piecewise functions, you can read:
https://brainly.com/question/3628123
Answer:
[tex]f(x) =\frac{x^3}{|x|}[/tex]
Step-by-step explanation:
Being an odd function means that [tex]f(-x) = -f(x)[/tex].
Graphically, it means the function will be symmetric across the origin.
So, the graph will have to look like the shown graph.
This graph looks quite similar to the graph [tex]f(x) = x^3[/tex], so we can use that as our parent function.
To get the graph to equal [tex]x^2[/tex] for x>0, we must divide [tex]x^3[/tex] by x.
However, this will simply result in the function [tex]f(x) = x^2[/tex].
If we divide by the absolute value of x however, the graph will look as desired.
1. Mr. Samuel had 13 notes in his wallet. They consist of $1. $5 and $10 notes. The total amount of the notes adds up to $93. How many $10 notes are there in his wallet?
Answer:
8 $10 notes
Step-by-step explanation:
I started by working it backwards. $93-$3 equals $90. So we have three of our 13 notes. We need ten more. Well the most $10 notes we can have is 8. if we had 8 $10 notes that would give us $80. $90-$80=10. We can take ten and divide it by five so we have 2 $5 notes.
So in total he would have 8 $10 notes, 2 $5 notes, and $3 one dollar notes which adds up to 13 notes
Chen uses these digit cards.
5,6,9
She makes a 2-digit number and a 1-digit number.
She multiplies them together.
Her answer is a multiple of 10
What could Chens multiplication be?
_ _X_
Answer:
95 x 6
or 96 x 5
Step-by-step explanation:
Solve by logicIf you examine the three numbers, you will see that 5 is the only factor of 10.
If we multiply 5 by an even number, we get a multiple of 10.
If we multiply 5 by an odd number, we get a multiple of 5.
Therefore, the 1-digit number must be 5 or 6, and the last digit of the 2-digit number must be 6 or 5.
This means that the first digit of the 2-digit number has to be 9.
So the options are: 95 x 6 and 96 x 5
Proof56 x 9 = 504
59 x 6 = 354
65 x 9 = 585
69 x 5 = 345
95 x 6 = 570
96 x 5 = 480

Answer:
The slope equals the rise divided by the run:
Step-by-step explanation:
You can determine the slope of a line from its graph by looking at the rise and run. One characteristic of a line is that its slope is constant all the way along it. So, you can choose any 2 points along the graph of the line to figure out the slope.

Calculate the length of her kitchen.
m
ANSWER: 8.3
EXPLANATION :perimeter= (length + width)2
29.6 m = ( length+6.5)2
29.6 = 2l + 13
29.6 Subtract 13 = 2 lengths
16.6÷2 =2l ÷2

A jar has 28 cherry-flavored candies, 18 strawberry-flavored candies, and 20 orange-flavored candies. If a piece of candy is taken from the jar at random, what is the probability that it will be strawberry-flavored candy?
Group of answer choices
10/33
1/20
14/33
3/11
Answer:
3/11
Step-by-step explanation:
You add up all of the candies so 20+19+28 which is 66
18 is the number of strawberry candies so it becomes 18 over 66, 18/66
Symplify 18/66 and it becomes 3/11
