Answer:

468

Step-by-step explanation:

use the smallest digit in the hundreds place , that is 4

use the next smallest digit in the tens place, that is 6

use the next smallest digit in the units place, that is 8

smallest 3- digit number is 468

Answer: 468

Step-by-step explanation:

Numbers are= 9,6,4,8

Now, rearrange all numbers according to weight,

4<6<8<9

The smallest possible 3-digit number will be 468

The answers are given below:-

a) The exponential function is: [tex]y(t) = 500e^{-0.0117593}[/tex]

b) The rule is: [tex]y(t) = y(0)(\dfrac{358}{500})^{\frac{t}{8}[/tex]

c) The half-life of the element is of 16.599 days.

The mathematical expression  [tex]f(x) = e^x[/tex] denotes the exponential function. The phrase typically refers to the positive-valued function of a real variable, unless otherwise specified.

Following t days, the substance's amount's exponential function is given by:

[tex]y(t) = y(0)e^{-kt}[/tex]

For this problem, we have that:

y(0) = 500, y(8) = 358.

Hence we can solve for k as follows:

[tex]y(t) = y(0)e^{-kt}[/tex]

[tex]358=500e^{-8k}[/tex]

[tex]e^{-8k}=\dfrac{358}{500}[/tex]

[tex]lne^-8k}=ln0.716[/tex]

-8k = ln(0.716)

k = -ln(0.716)/8

k = 0.041759389.

Hence:

[tex]y(t) = 500e^{-0.0117593}[/tex]

For item b, 358/500 of the material is what is left over after each 8-day period, therefore f(t) = t/8, and the rule is as follows:

[tex]y(t) = y(0)(\dfrac{358}{500})^{\frac{t}{8}[/tex]

For item c, using the rule from item a, we have to find t for which y(t) = 0.5y(0), hence:

[tex]y(t) = y(0)e^{-0.0117593}[/tex]

[tex]0.5y(0)=y(0)e^{-0.0117593[/tex]

[tex]e^{-0.0117593}=0.5[/tex]

[tex]lne^{-0.0117593}=ln0.5[/tex]

-0.041759389t = ln(0.5)

t = -ln(0.5)/0.041759389

t = 16.599.

The half-life of the element is of 16.599 days.

Answer:

y=3m-3x

Step-by-step explanation:

[tex]m=x+\frac{y}{3} \\ \\ m-x=\frac{y}{3} \\ \\ y=3m-3x[/tex]

The height of the tank is h = 216/s^2, the surface area is s^2 + 864/s and the value of s is ∛432

The given parameters are

Volume = 216

Base length = s

Height = h

The base shape is a square.

So, we have

Volume = s^2h

This gives

216 = s^2h

Divide through by s^2

h = 216/s^2

Hence, the height of the tank is h = 216/s^2

This is calculated as

A = s^2 + 4sh

So, we have

A = s^2 + 4 * s * 216/s^2

Evaluate

A = s^2 + 4 * s * 216/s^2

This gives

A = s^2 + 864/s

Here, we have

A = s^2 + 864/s

Differentiate

A' = 2s - 864/s^2

Set to 0

2s - 864/s^2 = 0

Divide through by s

2 - 864/s^3 = 0

So, we have

864/s^3 = 2

This gives

2s^3 = 864

Divide by 2

s^3 = 432

Take the cube root

s = ∛432

Hence, the value of s is ∛432

The volume of concrete required for the first 12 steps is 132.6 cubic feet

Given data

the first step requires 1.7 cubic feet of concrete

the first 4 steps require a total of 17 cubic feet

the first term = a = 1.7

4th step =  n/2 ( 2a + ( n - 1 ) d )

d is common difference

n = number of terms

17 = 4/2 ( 2*1.7 + ( 4 - 1 ) d )

17 = 2( 3.4 + 3d )

8.5 = 3.4 + 3d

5.1 = 3d

3d = 5.1

d = 1.7

sum of AP at 12th step

12th = n/2 ( 2a + ( n - 1 ) d )

12th = 6( 2 * 1.7 + ( 12 - 1 ) * 1.7)

Answer:

$191.69

Step-by-step explanation:

Step-by-step explanation:

x = number of km bus from A drives until they meet.

y = number of km bus from B drives until they meet.

x/80 is the time for the bus from A to reach the meeting point.

x/70 is the time for the bus from B to reach the meeting point.

both times must be equal, as they start at the same time.

so,

x/80 = y/70

but then we also know that together they have traveled the full 52 km to meet.

so,

x + y = 52

x = 52 - y

with that we go into the first equation :

(52 - y)/80 = y/70

(52 - y)/8 = y/7

7×(52 - y)/8 = y

7×(52 - y) = 8y

364 - 7y = 8y

364 = 15y

y = 364/15 km = 24.26666666... km

x = 52 - y = (780-364)/15 = 416/15 = 27.73333333... km

they will meet after (using bus from B)

364/15 / 70/1 = 364/1050 hours

= 182/525 hours =

= 60×182/525 = 10920/525 minutes =

= 728/35 = 104/5 = 20.8 minutes =

= 20 minutes 60×8/10 seconds =

= 20 minutes 48 seconds

control (using bus from A) :

416/15 / 80/1 = 416/1200 hours =

= 26/75 hours =

= 60×26/75 = 1560/75 minutes =

The combination of numerical variables and operations expressed by the addition, subtraction, multiplication, and division signs is known as a mathematical expression. A place-value system gives a number's specific location within a series a value.

Karin's softball batting average is 0.304, whereas Cheryl's is 0.340. They have the same average, according to Karin.

Because the numbers 0.340 and 4 are in the tenth position, as opposed to 0.304 and 4, the values are different from one another.

Based on the fixed costs and the equilibrium point, the function for total costs would be TC = 300 + 100VC

The total cost that a company incurs for making a good or service is a combination of both the fixed cost and the variable cost.

The total variable cost is found as:

= Number of units produced x variable cost per unit

= 100 units x vc

= 100vc
