Answer:

750 pounds each

Step-by-step explanation:

You start with 4000 pounds, and 1000 goes into the big sandbox.

Now you have 3000 pounds left.

These 3000 pounds must be divided into 4 sandboxes, which means

3000/4= Small sandbox capacity=750 pounds

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

Step-by-step explanation:

If you climb up 5 flights of stairs will give zero. The correct option is D.

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that situations can be represented with an integer​ that, when combined with the opposite of −5​, makes​ 0.

If you climb up 5 flights of stairs it will give the positive value of 5 when it is added to -5 then it will give zero.

Therefore, If you climb up 5 flights of stairs will give zero. The correct option is D.

I got it right off of some other question

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).

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.

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).

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

$0.70 per letter, $1.50 flat fee

Step-by-step explanation:

\/

(-18y+14.1)+35y=26 -> 17y=11.9 -> y=0.7

The post office charges $0.70 to send one letter, and there is a flat fee of $1.50.

To 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.
