What is 23 % changed into a fraction
Answer:
23/100
Step-by-step explanation:
Any percent is out of 100, so you can just say 23/100. This works for any percentage but you can still simplify it. 23/100 is already in its simplest form so you can not simplify it any more. 23% in decimal form is 0.23.
Hey scientist has it the amount of rainfall during the afternoon is around 0.43 minutes and each hour what was the total amount of rain fall in three hours
Answer:
1.29 minutes
Step-by-step explanation:
The scientist has a record of the amount of rainfall during the afternoon as around 0.43 minutes in each hours.
Now, we have to calculate the total amount of rainfall in three hours.
As the each hour rainfall is of 0.43 minutes, so the total rainfall in three hours will be (0.43 × 3) = 1.29 minutes. (Answer)

Answer:
Leg length = 8.5Step-by-step explanation:
let x represent the leg length
if we use the Pythagorean theorem we get:
x² + x² = 12²
then
2x² = 12²
Then
x² = 144/2 = 72
then
x = √(72)

i am after 70 i am before 90 you say me when count by tens. what number am i?
80
The question implies that you're counting by tens & the number comes after 70 and before 90. This is the only number that fits this description.
Using logical concept, the value of the number in question will be 80.
Let the number be n ;
Value before, n = 70Value after, n = 90Difference between n and the preceeding and succeeding values is 10Hence, we have ;
70, n, 90
n - 70 = 10 - - (1)
90 - n = 10 - - - (2)
Using either of the two expressions, we can obtain the value of n :
n - 70 = 10
n = 10 + 70
n = 80
Hence, the number is 80

A. 20
B. 1,024
C. 125
D. 625
To simplify the expression 54, divide it by 2 and 3 to get the simplified result of 9.
Explanation:To simplify the expression 54, you need to consider the properties of the number 54. First, note that 54 is divisible by 2. Next, check if it is also divisible by 3. If it is, continue dividing by 3 until you can no longer do so. In this case, 54 is divisible by both 2 and 3, so you can simplify it as follows:
Divide 54 by 2: 54 ÷ 2 = 27Divide 27 by 3: 27 ÷ 3 = 9Therefore, the simplified expression 54 is equal to 9. So, the correct answer is A. 20.

A cylinder with a radius of 12cm and a height of 20cm has the same volume as a cone with a radius of 8cm. What is the height of the cone
Answer: 135cm
Step-by-step explanation
Volume of a cylinder = πr²h
Volume of a cone. = 1/3πr²h
The two shapes are both solid shapes.
Since the have same volume, we can then equate the two together and solve for the height of the cone.
Now make H the height and R the radius of the cylinder and h the height and r the radius of the cylinder.
Now equating the two
πR²H = 1/3πr²h
Now substitute for the values now
Multiply through by 3
3πR²H = πr²h
But π is common so it could be obliterated from the equation
3R²H = r²h
3 x 12² x 20 = 8² x h
3 x 144 x 20 = 64 x h
60 x 144 = 64h
8640. = 64h
Therefore
h = 8640/64
= 135cm

The value of [tex]\sec\theta =\pm\sqrt{\frac{11}{8}}[/tex].
Solution:
Given data:
[tex]$\tan^2\theta=\frac{3}{8}[/tex]
To find the value of [tex]\sec\theta:[/tex]
Using trigonometric identity,
[tex]\sec^2\theta=1+\tan^2\theta[/tex]
Substitute [tex]\tan^2\theta=\frac{3}{8}[/tex] in the identity, we get
[tex]$\Rightarrow \sec^2\theta=1+\frac{3}{8}[/tex]
1 can be written as [tex]\frac{1}{1}[/tex].
[tex]$ =\frac{1}{1} +\frac{3}{8}[/tex]
Do cross multiplication.
[tex]$ =\frac{8}{8} +\frac{3}{8}[/tex]
Denominators are same, so you can add the fractions.
[tex]$ =\frac{8+3}{8}[/tex]
[tex]$\Rightarrow \sec^2\theta =\frac{11}{8}[/tex]
Taking square root on both sides, we get
[tex]$\Rightarrow \sec\theta =\pm\sqrt{\frac{11}{8}}[/tex]
Option B is the correct answer.
Hence the value of [tex]\sec\theta =\pm\sqrt{\frac{11}{8}}[/tex].

it’s take 4 minutes to fill an empty aquarium to a depth of 2/5 meters. what is the unit rate in minutes per meter?
The unit rate is calculated by dividing the total quantity by the total number of units. In this case, it takes 4 minutes to fill the aquarium to a depth of 2/5 meters. So, the unit rate for filling the aquarium is 10 minutes per meter.
Explanation:To calculate the unit rate, you divide the total quantity by the total number of units. In this case, it takes 4 minutes to fill the aquarium to a depth of 2/5 meters. So, for the unit rate in minutes per meter, you would set up the division as follows:
4 minutes / (2/5) meters
When you divide 4 by 2/5, you actually multiply 4 by the reciprocal of 2/5, which is 5/2.
So, 4 * (5/2) = 10
Therefore, the unit rate for filling the aquarium is 10 minutes per meter.

A group of 8 friends (5 girls and 3 boys) plans to watch a movie, but they have only 5 tickets. How many different combinations of 5 friends could
possibly receive the tickets?
OA 13
OB 40
Oc 56
There are 56 different combinations of 5 friends that can be selected from the group of 8 friends (option C)
To determine the number of different combinations of 5 friends that can be selected from a group of 8 friends, we use the concept of combinations in combinatorial mathematics.
The number of ways to choose [tex]\( k \)[/tex] elements from a set of [tex]\( n \)[/tex] elements is given by the binomial coefficient [tex]\(\binom{n}{k}\)[/tex], which is calculated as:
[tex]\[\binom{n}{k} = \frac{n!}{k!(n-k)!}\][/tex]
In this scenario:
[tex]\( n = 8 \)[/tex] (total number of friends)
[tex]\( k = 5 \)[/tex] (number of tickets available, hence number of friends to be chosen)
We need to calculate [tex]\(\binom{8}{5}\)[/tex]:
[tex]\[\binom{8}{5} = \frac{8!}{5!(8-5)!} = \frac{8!}{5! \cdot 3!}\][/tex]
First, we calculate the factorials involved:
[tex]\( 8! = 8 \times 7 \times 6 \times 5 \times 4 \times 3 \times 2 \times 1 = 40320 \)[/tex]
[tex]\( 5! = 5 \times 4 \times 3 \times 2 \times 1 = 120 \)[/tex]
[tex]\( 3! = 3 \times 2 \times 1 = 6 \)[/tex]
Now, substitute these values into the binomial coefficient formula:
[tex]\[\binom{8}{5} = \frac{40320}{120 \times 6} = \frac{40320}{720} = 56\][/tex]
Therefore, there are [tex]\( 56 \)[/tex] different combinations of 5 friends that can be selected from the group of 8 friends.

Find the slope of the curve y=-3x-x^2 at the point (-1,2)
Answer:
slope = - 1
Step-by-step explanation:
The slope of the curve m is measured by
m = [tex]\frac{dy}{dx}[/tex] at x = a
Differentiate using the power rule
[tex]\frac{d}{dx}[/tex] (a[tex]x^{n}[/tex] ) = na[tex]x^{n-1}[/tex]
Given
y = - 3x - x², then
[tex]\frac{dy}{dx}[/tex] = - 3 - 2x
x = - 1 → [tex]\frac{dy}{dx}[/tex] = - 3 - 2(- 1) = - 3 + 2 = - 1 ← slope at (- 1, 2 )

Seventy people attended a concert. A general admission ticket is $4.75 and a student is $3.25 . If the box office collected $272.50 ,how many general admissions and how many student tickets were sold.
Answer:
Step-by-step explanation:
Let g = amount of general admission tickets
Let s = amount of student tickets
Since seventy people attended the concert, this includes the people who bought general admission tickets and the people who bought the student tickets. As a result, g + s = 70. A student ticket is $3.25, so it would be 3.25s and a general admission ticket is $4.75, so it would be 4.75g. Since there was $272.50 collected in all, the second equation would be 3.25s + 4.75g = 272. 50.
g + s = 70
4.75g + 3.25s = 272.50
Multiply the first equation by 3.25 (or 4.75) so that you can use elimination to get rid of one variable.
3.25g + 3.25s = 227.50
4.75g + 3.25s = 272.50
Now, you subtract so that you can eliminate s.
-1.50g = -45
g = 30
This means that there are 30 general admission tickets. Now, you substitute 30 in for g to find s.
30 + s = 75
Subtract 30 from both sides.
s = 45
This means that there are 30 general admission tickets and 45 student tickets.
Find the nth term in the geometric sequence 12, -3, 3/4
Answer:
12 (-0.25)ⁿ
Step-by-step explanation:
recall that the general form for each term in the geometric progression is
arⁿ
such that the geometric progression looks something like.
ar⁰, ar¹, ar², ar³, ....., arⁿ, ......
also note that r⁰ = 1, hence ar⁰ is simply a
hence the G.P can be written
a, ar, ar², ar³, ....., arⁿ, ......
also note that r can be obtained by simply dividing the 2nd term with the 1stterm. i.e
r = ar ÷ a
now we are given the first 3 terms in the GP as
12, -3, 3/4, ....
comparing with the GP in the previous paragraph, we can see that ,
a = first term = 12
also
r = 2nd term ÷ 1st term
= -3 ÷ 12
= -0.25
hence the nth term
= arⁿ
= 12 (-0.25)ⁿ
