THIS IS AREA OF CIRCLES PLS ANSWER
Answer:
75ft^2
Step-by-step explanation:
A = pi*r^2
The circle already gives the diameter and the diameter is two times the radius, so if you were to divide the diameter by two, you would get 5.
Knowing the radius is 5 and seeing how they replaced pi with 3 we can set up the equation.
3*(5)^2 = A
Simplify
3*25
Multiply
Area=75ft^2

Answer:
A. 6.75
Step-by-step explanation:
8x+18=4x+57
8x-4x=57-18
4x=39
4x+57=180-(8y+30)
39+57=180-8y-30
96=150-8y
8y=150-96
= 54
y= 54/8 = 6.75

Pentagon ABCDE is similar to pentagon PQRST. If the side length of pentagon ABCDE is 6 times the side length of pentagon PQRST, which
statement is true?
.A
The area of pentagon ABCDE is 6 times the area of pentagon PQRST
The area of pentagon ABCDE is 12 times the area of pentagon PQRST.
Ос.
The area of pentagon ABCDE is 36 times the area of pentagon PQRST.
D.
The area of pentagon ABCDE is 216 times the area of pentagon PQRST,
Answer: c
Step-by-step explanation:
The area of pentagon ABCDE is 36 times the area of pentagon PQRST. Therefore, the option C is the correct answer.
What is a pentagon?Any five-sided polygon or 5-gon is referred to as a pentagon. A basic pentagon's interior angles add up to 540°. A pentagon might be straightforward or self-intersecting.
We know the formula for the area of a pentagon, therefore, the area of the pentagon PQRST can be written as,
A= 1/4 ×√(5(5+25)×a²
Given that the side of the side length of pentagon ABCDE is 6 times the side length of pentagon PQRST, therefore, the area of the pentagon ABCDE can be written as,
Area of a ABCDE = 1/4 ×√(5(5+25)×(6a)²
= 1/4 ×√(5(5+25)×36a²
= 36A
Therefore, the option C is the correct answer.

A student was asked to identify the following numbers as rational or irrational. Determine if the student has made any mistakes. Choose ALL the INCORRECT answers. There may be more than one answer
Answer:
Yes they are wrong, rational & irrational ones down below.
Step-by-step explanation:
So, lets start this by asking, what is a rational and irrational number?
Rational numbers are literally any numbers that arent pi, e, or other symbols, as well as square roots.
Irrational numbers are exactly the opposite, being the numbers that are symbols, including square roots.
Note that the symbols listed above such as pi are values that are neverending.
Now, using what we know of rational and irrational numbers, let see which answers are rational and which are not.
So, we start off with:
-13/3
I do not see a square root.
I do not see a symbol such as pi either.
It is not a ever going number.(number that continues infinitly)
So -13/3 is a rational number.
Next we have [tex]\sqrt{37}[/tex]
immediatly we tell it has a square root.
So [tex]\sqrt{37}[/tex] is a irrational number.
Next we have 0.1234
This is not a every going number.
There isnt a square root.
And it isnt a symbol.
So 0.1234 is a rational number.
Next we have [tex]-\sqrt{100}[/tex]
Again, we can immediatly know it has a square root.
So [tex]-\sqrt{100}[/tex] is a irrational number.
Next we have -77
This is not every going.
It doesnt have a square root.
It doesnt have a symbol.
So -77 is a rational number.
Lastly we have [tex]-\sqrt{12}[/tex]
Like the other ones, we can imediatly tell it has a square root.
So [tex]-\sqrt{12}[/tex] is a irrational number.
Bascially, to answer further questions, here is the criteria for a number being rational:
It does not have a square root.It does not have a symbol.It is not a infinitly going on number.If one of these criterias are not met, then you know its a irrational number.

Answer:
B,48.2
Step-by-step explanation:
To solve this we need to use SOH, CAH, TOA
we have the adjacent and hypotonouse so it's easiest to use CAH
let theta (angle) = x
cos(x)=4/6
to cancel the cos mulitply both sides by cos^-1 (2nd --> cos)
x=48.1896851

Find the second, fourth, and eleventh terms of the sequence A(n) = 5 + (n - 1)(-3)
Answer:
2nd: 2
4th: -4
11th: -25
Step-by-step explanation:
When you substitute a number into the equation you get that number term. So, if you substituted in 1, you get the first term. To find the second term, you substitute in 2:
A(2) = 5 + (2 - 1)(-3)
A(2) = 5 + (1)(-3)
A(2) = 5 - 3
A(2) = 2
To get the 4th term you substitute in 4:
A(4) = 5 + (4 - 1)(-3)
A(4) = 5 + (3)(-3)
A(4) = 5 - 9
A(4) = -4
And we do the same for the 11th term:
A(11) = 5 + (11 - 1)(-3)
A(11) = 5 + (10)(-3)
A(11) = 5 - 30
A(11) = -25
In a candy store, a $12.00 jar of candy is labeled, "30% off." What is the discount as a dollar amount?
Answer:
8.40
Step-by-step explanation: This means the cost of the item to you is $8.4. You will pay $8.4 for a item with original price of $12 when discounted 30%. In this example, if you buy an item at $12 with 30% discount, you will pay 12 - 3.6 = 8.4 dollars.
Answer:
The new total will be $8.40.
Step-by-step explanation:
The 30% off discount gives you $3.60 off of your purchase.
5x−4y=−10
y=2x−5
x=x=x, equals
y=y=y, equals
Answer:
✎ ANSWER:-[tex]y = 2x - 5[/tex]
Substitute the value of y as 2x - 5 in the equation.
[tex]5x - 4y = - 10 \\ 5x - 4(2x - 5) = - 10 \\ 5x - 8x + 20 = - 10 \\ 5x - 8x = - 10 - 20 \\ - 3x = - 30 \\ x = \frac{ - 30}{ - 3} \\ x = 10[/tex]
Now, find the value of y
[tex]y = 2x - 5 \\ y = 2(10) - 5 \\ y = 20 - 5 \\ y = 15[/tex]
⎇ x = x = x, equals 10
⎇ y = y = y, equals 15
Answer:
if y = 2x-5
then in the second equation we can find the value of x
5x-4(2x-5) = -10
5x-8x+20 = -10
-3x = -30
x = 10
then the value of y = 20-5 = 15
therefore the value of x = 10 and y =15 (ans)

When a graph is symmetric about the origin, it is an function.
When a graph is symmetric about the y-axis, it is an function.
A function is considered if f(-x) =
f(x), and it is considered
=
if f(-x) = -f(x).
Answer:
odd; even; even; odd
Step-by-step explanation:
The answers are odd, even, even, and odd respectively the graph is symmetric about the y axis it is an even function.
What is a function?It is defined as a special type of relationship and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We know when the graph is symmetric about the origin it is an off function.
When the graph is symmetric about the y axis it is an even function.
When f(-x) = f(x) it is an even function
When f(-x) = -f(x) it is an odd function.
Thus, the answers are odd, even, even, and odd respectively the graph is symmetric about the y axis it is an even function.

Answer: 1) Using the order of operations, you first have to multiply the amount of each item by it's price, and then add those values. So for Pablo, you would do (0.50 x 1) + (0.75 x 3) + (1.25 x 3) and solve within the parentheses to get .50+2.25+3.75=$6.50
2) For Laurie, use the same method from #1. First multiply and then add, like so: (0.5 x 2) + (1.25 x 3) + (0.75 x 3) ---> 1+3.75+2.25, which equals $7
3) Laurie > Pablo
$7.00 > $6.50
Step-by-step explanation:
The term order of operations is also known as PEMDAS

Answer:
16. r = 20
t = 48
17. a = 104
b = 175
19. [tex]\frac{144}{20} =\frac{252}{35}[/tex]
7.2 = 7.2
20. [tex]\frac{27}{18}= \frac{21}{14}[/tex]

23. [tex]\frac{y}{2}: \frac{200}{80}[/tex]
50 milligrams of medication
Step-by-step explanation:
16. [tex]\frac{r}{32} =\frac{5}{8} =\frac{30}{t}[/tex]
8 · 4 = 32
5 · 4 = 20
r = 20
5 · 6 = 30
8 · 6 = 48
t = 48
17. [tex]\frac{52}{a} =\frac{10}{20} =\frac{b}{350}[/tex]
Here is a different method.
[tex]\frac{10}{20} =\frac{1}{2}[/tex]
52 · 2 = 104
a = 104
350 ÷ 2 = 175
b = 175
22.
[tex]\frac{8}{3} :\frac{584}{y}[/tex]
8 · y = 3 · 584
8y = 1752
8y ÷ 8 = 1752 ÷ 8
y = 219
23.
[tex]\frac{y}{2}: \frac{200}{80}[/tex]
y · 80 = 200 · 20
80y = 4000
80y ÷ 80 = 4000 ÷ 80
y = 50
