An aquarium contained an equal number of horseshoe crabs and sea stars. After 15 horseshoe crabs were removed and 27 sea stars were removed, the ratio of horseshoe crabs to sea stars was 5:3. How many horseshoe crabs and sea stars were there at first? Solve this problem and explain your reasoning.
Answer:
45 horseshoe crabs and 45 sea stars
Step-by-step explanation:
The aquarium initially contained x crabs and x sea stars.
"After 15 horseshoe crabs and 27 sea stars are removed the ratio of horseshoe crabs to sea stars is 5:3"
(x-15):(x-27) = 5:3
(x-15)/(x-27) = 5/3
3(x-15) = 5(x-27)
3x-45 = 5x-135
90 = 2x
x = 45

On a large college campus, the students are able to get free copies of the school newspaper,the local newspaper, and a national paper. Ninety percent of the students read at least one of thepapers, 40% read only the school newspaper, 20% read only the local paper, 5% read only thenational paper, and 2% read all three papers. Fifty percent read the school newspaper, and 5%read the school and national newspapers. A randomly selected student is asked whether he orshe reads the school, local, or national paper. Express each of the following events in setnotation and find the percentage of students represented by each.a The student does not read any paper.b. The student reads the local paper.c. The student reads exactly two papers.d. The student reads at least two papers.
Answer:
a) The percentage that the student does not read any paper is 10%
b) The percentage that the student reads the local paper is 40%
c) the percentage that the student reads exactly two papers is 23%
d) the percentage that the student reads at least two papers is 25%
Step-by-step explanation:
Given the data in the question;
as illustrated in the Venn diagram below,
a)The student does not read any paper;
The percentage that the student does not read any paper will be;
100% - 90% = 10%
Therefore, The percentage that the student does not read any paper is 10%
b) The percentage that the student reads the local paper;
from the Venn diagram below;
⇒ ( 20 + 15 + 3 + 2 )%
= 40%
Therefore, The percentage that the student reads the local paper is 40%
c) The percentage that the student reads exactly two papers
⇒ ( 15 + 5 + 3 )%
= 23%
Therefore, the percentage that the student reads exactly two papers is 23%
d) The percentage that the student reads at least two papers;
⇒( 15 + 5 + 3 + 2 )%
= 25%
Therefore, the percentage that the student reads at least two papers is 25%

Step-by-step explanation:
i got this
28 x 15=420
420 x 3.14= 1318.8
Answer:
243.37 in^2
Step-by-step explanation:
large rectangle=28x15=420 (now we need to deduct the circular areas)
circular area =7.5^2(3.14)=176.63 (radius^2xPi) (this is for a full circle which accounts for the two semi circles)
420-176.63=243.37

Answer:
D) [tex]\frac{(-p)}{(-3q)}[/tex]
Step-by-step explanation:
This option is the only correct one. To solve for this, insert the numbers into the equation: [tex]\frac{(-6)}{(-3x2)}[/tex]. To solve this, first multiply -3 s 2 at the denominator to get -6. Now divide -6 divided by -6 to get 1. The number 1 is greater than -9. All of the other options have answers that equal -9.

A Data Scientist of a Fortune 500 banking firm is looking at the relationships between various age groups of adults and types of investments portfolios. He is looking at a Chi Square distribution in his statistical software. What is the probability that x is larger than 12 when df = 19?
Answer:
The probability that x is larger than 12 when df = 19 = 0.100
Step-by-step explanation:
We are supposed to find the probability value at x>12 at degree of freedom equals to 19.
P(x>12)
By looking at the chi square table we can see, at df = 19 and x>12, P(x>12) is equal to 0.100
because at df = 19, the least x values is 27.2036 for which (Px=27.2036) or (Px>12) = 0.100

I had $13.00. My Mom gave $10.00. My Dad gave $30.00. My Aunt, My Uncle and grandma gave me $100.00. I had another $7.00. How much did I have?
Answer:
Step-by-step explanation:
u had $13. ur mom gave u $10. ur dad gave u $30. ur aunt, uncle, and grandma gives u $100. u had another $7. u have a total of $160.
100 + 30 = 130 + 10 = 140 + 13 = 153 + 7 = $160Answer:
$360
Step-by-step explanation:
Start off with 13, add 10 makes it 23
23 + 30 = 53
Aunt, Uncle, and grandma each give you 100
100 x 3 = 300
300 + 53 = 353 + 7 = $360

Monica paid sales tax of $105 when she bought a new TV. If the sales tax is 5%, what was the cost of the TV?
Answer:
$31.5
Step-by-step explanation:
X * 5% = $1.50
X = $1.50 / 5%
Or by using simple rule of three:
If 5% is $1.50
Then 100% is X
So you obtain = $30
Now you just need to sum The net prices and the taxes
Net + tax = Total Charge
$30 + $1.5 = $31.5

(x-2)^2-6(x-2)+5=0
Find a Value of X
Answer:
The values of x are:
[tex]x=3,\:x=7[/tex]
Step-by-step explanation:
Given the expression
[tex](x-2)^2-6(x-2)+5=0[/tex]
Expand (x - 2)² = x² -4x + 4
[tex]x^2-4x+4-6\left(x-2\right)+5=0[/tex]
Expand: -6(x - 2) = -6x + 12
[tex]x^2-4x+4-6x+12+5=0[/tex]
simplifying
[tex]x^2-10x+21=0[/tex]
Factor x² -10x + 21: (x - 3) (x - 7)
[tex]\left(x-3\right)\left(x-7\right)=0[/tex]
Using the zero factor principle
if ab=0, then a=0 or b=0 (or both a=0 and b=0)
[tex]x-3=0\quad \mathrm{or}\quad \:x-7=0[/tex]
solving x - 3 = 0
x - 3 = 0
Adding 3 to both sides
[tex]x-3+3=0+3[/tex]
simplify
x = 3
solving x - 7 = 0
x - 7 = 0
Adding 7 to both sides
[tex]x-7+7=0+7[/tex]
Simplify
x = 7
Therefore, the values of x are:
[tex]x=3,\:x=7[/tex]

Bir kırtasiyeci aldığı kalemlerin tanesini

Bu kırtasiyeci kaç kalem alıp satmış-

A) 125 B) 120 C) 115 D) 110
Answer: Option B: 120.
Step-by-step explanation:
I will answer in English
This problem can be translated to:
A man bought N pens, (at a cost C) if he sells each pen at 2 lira, he will have a profit of 40 lira.
If he sells each pen at 1.5 lira, he will loss a total of 20 lira.
We want to find N, the number of pens that he bought.
if he sells the N pens at 2 lira each, the revenue is:
N*2 lira
And the profit is the difference between the revenue and the cost, then the profit (40 lira in this case) is:
N*2 lira - C = 40 lira.
When he sells each pen at 1.5 lira the equation is:
N*(1.5 lira) - C = -20 lira.
Then we have two equations:
N*2 lira - C = 40 lira.
N*(1.5 lira) - C = -20 lira.
To solve this we need to isolate the variable C in one of the equations, i will isolate C in the second equation:
N*(1.5 lira) + 20 lira = C.
Now we can replace this in the first equation to get:
N*(2 lira) - (N*(1.5 lira) + 20 lira) = 40 lira.
We can solve this for N.
N*(2 lira) - N*(1.5 lira) - 20 lira = 40 lira
N*(2 lira - 1.5 lira) = 60 lira
N*(0.5 lira) = 60 lira
N = (60lira/0.5lira) = 120
N = 120
This means that he bought 120 pens.
The correct option is B.
0.4y − 0.2y + 10 = 11.8
Answer:
0.2y+10
Step-by-step explanation:
Answer:
We have this equation:
0.4y - 0.2y + 10 = 11.8
You can simplify
0.2y + 10 = 11.8
Then, you can substract 10 in both sides:
0.2y = 11.8 - 10
0.2y = 1.8
You can now divide right and left side by 0.2 and get y:
0.2y/0.2 = 1.8/0.2
y = 14

Consider the expression.
6 · 60 · 6–3
Which statements are true about the expression? Check all that apply.
The 6 without an exponent is equivalent to the 6 having a 0 exponent.
The sum of the exponents is 2.
Multiply the exponents to simplify the expression.
The expression has a value of StartFraction 1 Over 36 EndFraction.
An equivalent expression is 65 · 6-7.
Answer:
4. The expression has a value of 1/36 . True
5. An equivalent expression is (6)^5. (6)^- 7 True
Step-by-step explanation: Not true. The 6 without an exponent is equivalent to the 6 having a 0 exponent.
Any number having an exponent zero has a value equal to 1.
6 · (6)^0 · (6)^–3
= 6.1.1/216
= 1/36
= (6)^-2
2. The sum of exponents is 2.
False ( the sum of exponents is -2)
3.Multiply the exponents to solve the expression .
False when the bases are the same the exponents are added or subtracted.
4. The expression has a value of 1/36 .
True
5. An equivalent expression is (6)^5. (6)^- 7
True
