125% of e is 30 means then the value of e is 24.
Step-by-step explanation:
By simplifying the given statement we can write it as[tex]\frac{125}{100}[/tex] [tex]\times e = 30[/tex]
So to find the e, we should keep e on one side the take the remaining terms on the other side. So after rearranging, we can obtain the equation e = [tex]\frac{30\times100}{125}[/tex]So now canceling the favorable terms we can get 24.The unknown number e from the given question is 24
How to find percentage125% of e is 30
125 / 100 × e = 30
1.25e = 30
divide both sides by 1.25e = 30 / 1.25
e = 24
Therefore, the unknown number e from the given question is 24

What is the prime factorization for 356
The prime factorization of 356 is found by dividing it by the smallest prime numbers step by step, leading to the solution of 2×2×89.
Explanation:The prime factorization of 356 involves breaking down the number into its prime factors, which are numbers that can only be divided by 1 and themselves. To start, we look for the smallest prime number that can divide 356. We find that 2 is the smallest prime factor of 356 (since 356 is an even number).
Dividing 356 by 2, we get 178. Continuing this process, 178 is also even, so we divide by 2 again to get 89. Upon reaching 89, we find that it is a prime number because it cannot be divided evenly by any number other than 1 and itself.
Therefore, the prime factorization of 356 is 2×2×89. This means that 356 can be expressed as a product of these prime numbers.
An annual membership at a swim club cost $30. Members must also pay $5 monthly locker fee, and $2 fee each time they use the facility. Which of the following can be used to find the total annual cost (A) for a membership? (hint: there are 12 months in a year)
Answer:
30+(5X12)+2x=90X2x
Step-by-step explanation:
5x12= 60
60+30=90
90x2x
We don't know how many times they use the facility so it stays 2x and you have to times that by 90 since that's the total cost minus the 2x.
Fina wants to use substitution to solve the system of equations. explain what she needs to do before using substitution. then solve the system of equations:
2x - y = 3
-1.5x + 3y = -18
To solve the system of equations using substitution, Fina needs to isolate one variable and substitute it into the other equation. The solution to the system of equations is x = -3 and y = -9.
Explanation:To solve this system of equations using substitution, Fina needs to isolate one variable in one of the equations and then substitute that expression into the other equation.
Here are the steps:
Choose one equation and isolate one variable. Let's isolate x in the first equation: 2x - y = 3. Add y to both sides: 2x = y + 3 and divide by 2: x = (y + 3)/2.
Substitute the expression for x in the other equation. Replace x in the second equation with (y + 3)/2: -1.5((y + 3)/2) + 3y = -18.
Solve the equation for y. Simplify the equation: -1.5y - 4.5 + 3y = -18. Combine like terms: 1.5y - 4.5 = -18. Add 4.5 to both sides: 1.5y = -13.5. Divide by 1.5: y = -9.
Substitute the value of y back into the expression for x to find its value. Replace y in x = (y + 3)/2 with -9: x = (-9 + 3)/2 = -6/2 = -3.
Therefore, the solution to the system of equations is x = -3 and y = -9.

A waitress sold 11 ribeye steak dinners and 12 grilled salmon dinners, totaling $560.63 on a particular day. Another day she sold 16 ribeye steak dinners and 6 grilled salmon dinners, totaling $584.46. How much did each type of dinner cost?
The cost of each ribeye steak dinner is $ 29 and cost of each grilled salmon dinner is $ 20
Solution:
Let "a" be the cost of each ribeye steak dinners
Let "b" be the cost of each grilled salmon dinners
A waitress sold 11 ribeye steak dinners and 12 grilled salmon dinners, totaling $560.63 on a particular day
Thus we frame a equation as:
11 x cost of each ribeye steak dinners + 12 x cost of each grilled salmon dinners = 560.63
[tex]11 \times a + 12 \times b = 560.63[/tex]
11a + 12b = 560.63 -------- eqn 1
Another day she sold 16 ribeye steak dinners and 6 grilled salmon dinners, totaling $584.46
Thus we frame a equation as:
16 x cost of each ribeye steak dinners + 6 x cost of each grilled salmon dinners = 584.46
[tex]16 \times a + 6 \times b = 584.46[/tex]
16a + 6b = 584.46 ------------ eqn 2
Let us solve eqn 1 and eqn 2
Multiply eqn 2 by 2
32a + 12b = 1168.92 ------- eqn 3
Subtract eqn 1 from eqn 3
32a + 12b = 1168.92
11a + 12b = 560.63
( - ) ----------------
21a = 1168.92 - 560.63
21a = 608.29
Divide both sides by 21
[tex]a = 28.96 \approx 29[/tex]
Substitute a = 29 in eqn 1
11(29) + 12b = 560.63
319 + 12b = 560.63
12b = 560.63 - 319
12b = 214.63
Divide both sides by 12
[tex]b = 20.13 \approx 20[/tex]
Thus cost of each ribeye steak dinner is $ 29 and cost of each grilled salmon dinner is $ 20

What is the maximum height in feet of the object?
How long will it take the object to reach its maximum height?
Answer:
It will take the object 2 seconds to reach the maximum height.
Step-by-step explanation:
The original equation is [tex]h=-14t^2+56t+60[/tex].
The object reaches the maximum height when derivative of [tex]h[/tex] is zero
[tex]\frac{dh}{dt}=0[/tex]
So let us take evaluate the derivative of [tex]h[/tex]
[tex]\frac{dh}{dt} =\frac{d}{dt} (-14t^2+56t+60)=\frac{d}{dt} (-14t^2)+\frac{d}{dt}(56t)+\frac{d}{dt} (60)[/tex]
[tex]=-28t+56[/tex]
this must be equal to 0:
[tex]-28t+56=0[/tex]
[tex]t=\frac{-56}{-28}[/tex]
[tex]\boxed{ t=2}[/tex]
It will take the object 2 seconds to reach the maximum height.

Identify the formula for finding the nth term of an arithmetic sequence, where A(n) is the nth term of an arithmetic sequence, a is the first term,n is the term number and d is the common difference.
Option D: A(n) = a + (n – 1) d
Solution:
To identify the formula for finding the nth term of an arithmetic sequence.
Let a be the first term.
d be the common difference of the each term.
n be the term of the number.
A(n) be the nth term of the arithmetic sequence.
Arithmetic formula:
A(n) = a + (n – 1) d
Example: 1, 4, 7, 10, 13, 16, 19, ...
This is a arithmetic sequence.
a = 1, d = 4 – 1 = 3.
To find the 5th term:
Substitute this in the above formula, we get
A(n) = a + (n – 1) d
A(5) = 1 + (5 – 1) 3
= 1 + 4(3)
= 1 + 12
A(5) = 13
In the given sequence 5th term is 13.
Hence Option D is the correct answer.
A(n) = a + (n – 1) d
Answer:
A(n) = a + (n - 1)d

81 is 18% of what number?
Answer:
n = 450
Step-by-step explanation:
18%·n = 81
18·n/100 = 81
18n = 8100
n = 8100 : 18
n = 450
Answer:
81 is 18% of 450.
Step-by-step explanation:
81 ÷ 18 = 4.5
4.5 x 100 = 450

Answer: [tex]average\ rate\ of\ change\approx-3[/tex]
Step-by-step explanation:
For this exercise you need to use the following formula:
[tex]average\ rate\ of\ change=\frac{f(b)-f(a)}{b-a}[/tex]
You need to find the average rate of change of the given function g(x) over the following interval:
[tex][-1,2][/tex]
So, you can see in the table that the point whose x-coordinate is -1, is:
[tex](-1,5)[/tex]
And the point whose x-coordinate is 2, is:
[tex](2,-3)[/tex]
Knowing this, let be:
[tex]a=-1\\f(a)=5\\\\b=2\\f(b)=-3[/tex]
Now you can substitute values into the formula:
[tex]average\ rate\ of\ change=\frac{-3-5}{2-(-1)}[/tex]
Finally, evaluating, you get that the average rate of change over the interval indicated in the exercise, is:
[tex]average\ rate\ of\ change=\frac{-8}{3}\\\\average\ rate\ of\ change=-2.66\\\\average\ rate\ of\ change\approx-3[/tex]

Step-by-step explanation:
we have
[tex]\frac{2}{5}=2m+\frac{11}{8}[/tex]
Solve for m
That means ----> Isolate the variable m
Multiply both sides by 40 to remove the fractions
Note: 40=(8)(5)
[tex](40)\frac{2}{5}=(40)2m+(40)\frac{11}{8}[/tex]
[tex]16=80m+55[/tex]
subtract 55 both sides
[tex]16-55=80m\\-39=80m[/tex]
Divided by 80 both sides

Using the digits 0 to 9, at most one time each, fill in the boxes to create a square, with one of the vertices at (2,3). Hint: 2 and 3 are already used (so they cannot be used again); not all numbers will be used.
Answer:
A(2,3), B(6,4), C(5,8), D(1,7)
Step-by-step explanation:
We were given the initial vertex at (2,3).
We want to create a square using the digits 0 to 9, at most one time each.
Keeping in mind the following properties of a square:
All sides are congruent
All angles are right angles
Hence the other three vertices are: B(6,4), C(5,8), D(1,7)
See attachment.
The question is about forming a square using unique digits from 0 to 9 to form coordinates with one vertex at (2,3). The coordinates of the square are (2,3), (4,3), (4,5) and (2,5) using digits 0,2,3,4 and 5.
Explanation:This type of problem is a geometric shape puzzle that involves basic principles of coordinate geometry and the usage of digits 0 to 9. Let's consider the point (2,3) as the bottom-left vertex of the square.
We know that a square has all sides equal, so we can choose point (4,3) as the bottom-right vertex (2+2=4), then (4,5) as the top-right vertex (3+2=5), and finally (2,5) as the top-left vertex.
We used the numbers 0,2,3,4,5 from the set of digits from 0 to 9.
