A) The total number of girl
B) The total number of student
Step-by-step explanation:
3000 [tex] 3000 \div 30 = 1000[/tex][tex]3000 \times 30 = 90000[/tex]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.

Ivan says that the shape at the right is n octagon. Do you agree or disagree? Explain
Answer:
Disagree
Step-by-step explanation:
An octagon has eight sides while the shape on the right has nine sides.
Answer:
No
Step-by-step explanation:
The shape shown in the picture has 9 sides(you can count) and therefore is not an octagon because octagons only have 8 sides.

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.

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.

what's the value of "x"? Show all your work.
Answer:
x=9
Step-by-step explanation:

x²+6²=(√117)²
x²+36=117
x²=81
x=9
Answer:
3[tex]\sqrt{17}[/tex] or 12.37 cm
Step-by-step explanation:
use the Pythagorean Theorem:
6² + [tex]\sqrt{117}[/tex]² = x²
36 + 117 = x²
x² = 153
x = [tex]\sqrt{153}[/tex] which is [tex]\sqrt{9}[/tex][tex]\sqrt{17}[/tex] or 3[tex]\sqrt{17}[/tex]
in decimal form, 'x' is approx 12.37
Can someone please help!! Due tonight!! I’ll give brainliest
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

M/D - Multiplication/Division (whichever comes first in the equation)
A/S - Addition/Subtraction (whichever comes first)

use the inverse operation to solve the following equation w + 125.2 = 255
Answer:
w=129.8
Step-by-step explanation:
w + 125.2 = 255
-125.2
w=225-125.2
w=129.8
Answer:
Hope this helps please mark me as branlist.
Step-by-step explanation:
Subtract 125.2 from both sides:
w=125.2=255
w=125.2-125.2=255-125.2
w=255-125.2
w=129.8

Answer:
16 meters
Step-by-step explanation:
[tex] In\: \odot F, \: \overline {RS} [/tex] is tangent to the circle at point R and FR is radius.
[tex] \therefore RF\perp RS[/tex] (Tangent radius theorem)
[tex] \therefore m\angle FRS = 90\degree [/tex]
So, [tex] \triangle FRS[/tex] is right angled triangle and FS is its hypotenuse.
Let FR = FT = r
FS = FT + ST = r + 9
Now, by Pythagoras theorem:
[tex]FR^2 + RS^2 = FS^2 \\ \therefore r^2 + (15)^2 = (r + 9)^2 \\ \therefore \cancel{ r^2} +225 = \cancel{ r^2} + 18r + 81\\ \therefore \: 225 = 18r + 81 \\ \therefore \: 225 - 81= 18r \\ \therefore \: 144= 18r \\ \therefore \: r = \frac{144}{18} \\ \therefore \: r =8 \: m\\ \implies \: d = 2r = 2(8) = 16 \: m[/tex]

Two phone companies one is 11/+.16/ min And another is 20+.11/min How many minutes will make both equal amounts
Answer:
Company one charges $11 + $0.16 per min.
Then if you talk for x minutes, the cost will be:
C₁(x) = $11 + ($0.16 per min)*x
For company two, the prize is $20 + $0.11 per min, and if yo talk for x minutes, the cost will be:
C₂(x) = $20 + ($0.11 per min)*x
Now we want to find the value of x, the number of minutes, such that the cost is the same with both companies.
C₁(x) = C₂(x)
$11 + ($0.16 per min)*x = $20 + ($0.11 per min)*x
($0.16 per min)*x - ($0.11 per min)*x = $20 - $11
($0.05 per min)*x = $9
x = $9/($0.05 per min) = 180 mins
If you speak for 180 minutes, the cost is the same in both companies.
in 2decimal places 39.98015
Answer:
39.98
Explanation:
39.98015
0 < 5, so 2nd decimal stays at 8
Answer:39.98
Step-by-step explanation:
Hey! I’m not exactly sure what you’re asking, but if the question is how to write that number in only two decimal places, it would be 39.98. We would round it up or down in the hundredths place because that is the second decimal place. Since the number behind the 8 is 0, we can’t round up or down so we would just leave it how it is and cut off the rest.
Hope this helped! :D

23. 5 milligrams
Step-by-step explanation:
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]

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

Answer:
73.5
Step-by-step explanation:
Please find the complete question in the attached image
Remember the notation SOHCAHTOA
We would be using cos because we have been given the hypotenuse and we are to determine the adjacent value
cos 37 = adjacent / hypotenuse
cos 37 = adjacent / 92
0.7986 = adjacent / 92
adjacent = 0.7986 x 92 = 73.5
What value of x makes the equation x+ 38 = 72 true?
Answer:
x = 34
Step-by-step explanation:
Given
x + 38 = 72 ( subtract 38 from both sides )
x = 34
Answer:
X=34
Step-by-step explanation:
Well, what you can do is bring the 38 to the other side and make it negative so you can subtract 38 with the 72. The 72-38 is= 34 and so x= 34
x+38=72
x=72-38
x=34
