the maximum mark of 60 students is 100 if it range is 75 the minimum work step by step
Answers
Answer:
25
Step-by-step explanation:
Range is the difference between the maximum and minimum value.
Range = Maximum - minimum
minimum = Maximum - range = 100 - 75 = 25
Answer:
25
Step-by-step explanation:
Range (R) = Max - Min
We change this to Min = Max - Range.
Let x be the minimum
x = 100 - 75
x = 25
The range is 25

a post office always charges a flat one time fee for any order. one time, michael sent 35 letters and paid 26 dollars. the next time, he sent 18 letters and paid $14.10. how much does the post office charge to send one letter? what is the flat fee?
Answers
Answer:
$0.70 per letter, $1.50 flat fee
Step-by-step explanation:
x+18y=14.1 -> x=-18y+14.1
x+35y=26
|
\/
(-18y+14.1)+35y=26 -> 17y=11.9 -> y=0.7
|
\/
x+35(0.7)=26 -> x+24.5=26 -> x=1.5
|
\/
y=0.7
x=1.5
Hope this helps. :)
The post office charges $0.70 to send one letter, and there is a flat fee of $1.50.
How to determine the the flat fee (F) charged by the post officeTo find the cost of sending one letter, we need to determine the flat fee charged by the post office.
Let's denote the flat fee as 'F' and the cost per letter as 'C'.
From the given information, we can set up the following equations:
Equation 1: F + 35C = 26
Equation 2: F + 18C = 14.10
We can solve this system of equations to find the values of F and C.
First, we subtract Equation 2 from Equation 1 to eliminate F:
(F + 35C) - (F + 18C) = 26 - 14.10
17C = 11.90
Now, we divide both sides of the equation by 17 to solve for C:
C = 11.90 / 17
C ≈ 0.70
Therefore, the cost to send one letter (C) is approximately $0.70.
To find the flat fee (F), we can substitute the value of C into either Equation 1 or Equation 2. Let's use Equation 1:
F + 35(0.70) = 26
F + 24.50 = 26
F = 26 - 24.50
F = 1.50
Therefore, the flat fee (F) charged by the post office is $1.50.

Answer:
V = 27/16 units^3, or 1 11/16 units^3
Step-by-step explanation:
Here the base area is 3 3/8 units^2, and the height is 2 units.
To find the volume, we multiply the base area by the height, obtaining:
V = (27/8)(2) units^3, or
V = 27/16 units^3, or 1 11/16 units^3
Answer:
V = 6 1/4 units ^3
Step-by-step explanation:
We know the area of the base
V = Bh where B is the area of the base
V = 3 3/8 * 2
Changing the mixed number to an improper fraction
V = (8*3+3 )/8 * 2
V = 27/8 *2
V = 27/4
Changing back to a mixed number
V = 6 1/4 units ^3

Answers
Answer:
750 pounds each
Step-by-step explanation:
You start with 4000 pounds, and 1000 goes into the big sandbox.

These 3000 pounds must be divided into 4 sandboxes, which means
3000/4= Small sandbox capacity=750 pounds
A function is shown: f(x) = 16x2 − 1. Choose the equivalent function that best shows the x-intercepts on the graph.
Answers
Answer:
Step-by-step explanation:
f(x) = 16x² - 1
The x-intercepts are the roots, i.e., the values of x for which f(x) = 0.
Use the Quadratic Formula to determine the roots.
x = [0±√0²-4·16(-1)]/[2·16] = ±√64/32 = ±8/32 = ±¼
f(x) = 16(x-¼)(x+¼) = (4x-1)(4x+1)
The function which is equivalent to f(x)=16[tex]x^{2}[/tex]-1 is f(x)=(4x+1)(4x-1) and x intercept lies at (1/4,0),(1/4,0).
What is function?Function is relationship between two or more that are variables expressed in equal to form. In a function each value of x must have a corresponding value of y.
How to solve a function?The function which is being give to us is f(x)=16[tex]x^{2}[/tex]-1 and we have to find the equivalent function that best shows the x intercepts on the graph.
f(x)=16[tex]x^{2}[/tex]-1
We can find the factors of the expression 16[tex]x^{2}[/tex]-1.
f(x)=[tex](4x)^{2} -(1)^{2}[/tex]
=(4x+1)(4x-1) [We know that [tex]a^{2} -b^{2}[/tex]=(a+b)(a-b)]
Now we have to find the x intercept. We know that x intercept is a point at which the line touches the x axis means y coordinate will be zero at that point. So we have to put the value of f(x)=0
(4x-1)(4x+1)=0
It can be like under:
4x-1=0,4x+1=0
x=1/4,-1/4
Hence the function which is equivalent to f(x)=16[tex]x^{2}[/tex]-1 is f(x)=(4x+1)(4x-1) and x intercept lies at two points (-1/4,0,(1/4,0).
