Answer:In the number, 687,760, there are two 7s; one is at a place value of hundred and the other is at thousand.

Hence, the higher place value 7 is 10 times greater than lower place value 7. Every consecutive place value is 10 times greater than the right one.

Step-by-step explanation:

Probability that this person uses at least 2 facilities is; 0.556

We are told that 14 people use all three facilities. This means:

36 − 14 = 22 represents the number of people that are using the gym and the pool but no the track.

35 − 14 = 21 represents the number of people that are using the pool and the track but no the gym.

32 − 14 = 18 represents the number of people that are using the gym and the track but no the pool.

Thus, total number of people that use at least 2 facilities = 14 + 22 + 21 + 18 = 75

Since total number of people at the sports center is 135, then it means that;

Probability that this person uses at least 2 facilities = 75/135 = 0.556

The value of the t in the linear equation is 10 approximately.

According to the statement

We have to find that the value of the t.

So, For this purpose, we know that the

The definition of a linear equation is an algebraic equation in which each term has an exponent of one and the graphing of the equation results in a straight line.

From the given information:

The equations are:

h(t) = 0.5t + 8.

h(t) = −4.9(t − 5) + 38.

Then

= 0.5t + 8

= −4.9(t − 5) + 38.

And

= 0.5t + 8

= −4.9t + 24.5 + 38.

And

= 0.5t + 8

= −4.9t + 62.5

Now,

Subtact the equations then

= 0.5t + 8 - (−4.9t + 62.5)

= 0.5t + 8 + 4.9t - 62.5

= 0.5t + 4.9t - 62.5+8

=  5.4t -54.5

Then

5.4t = 54.5

t = 54.5/5.4

t = 10.092.

The value of r so that the line passes through (r, 7), (3, 4) and slope of - 3 / 5 is - 2.

The slope of the line is given as m = - 3 / 5.

The pair of point are (r, 7)(3, 4).

Using slope intercept form equation is as follows:

y = mx + b

where

Therefore, using (3, 4) we will find the y-intercept

y = - 3 / 5 x + b

4 = -3  / 5 (3) + b

4 = - 9 / 5 + b

b = 4 + 9 / 5

b = 20 + 9/ 5

b = 29 / 5

Therefore, the equation of the line is as follows;

y = - 3 / 5x + 29 / 5

Hence, let's find r (r, 7)

7 = -3 / 5(r) + 29 / 5

7 - 29 / 5 = -3 / 5 r

35 - 29/ 5 =  -3 / 5 r

6 / 5 = - 3 / 5 r

-15r = 30

divide both sides by -15

r = 30 / -15

r = -2

you save $253.33 if you purchase this desk on sale.

We know that the price in sale of the desk is $380, and this is given by a discount of the 40% of the original price.

So, if the original price is defined by the variable P, the amoun you save by buying the discounted deck is:

P - $380

Now, remember that the discounted price should be written in terms of P as:

$380 = P*(1 - 0.4) = P*0.6

Where 0.4 is the decimal form of 40%.

With that we can find the value of P as:

P = $380/0.6

Then the amount that you save is given by:

P - $380 = $380/0.6 - $380 = $253.33

The stack of pennies is an illustration of linear equation.

The equation for n pennies is: h(n) = 7.6 + 1.52nh(n)=7.6+1.52n .

h(1.52) does not make sense

(a) Complete the table

From the question, we have:

Start = 5Start=5 ---- the number of penny he started with

Thick = 1.52Thick=1.52 --- the thickness of a penny

The height of n pennies is calculated using:

h(n) = (Start + n) \times Thickh(n)=(Start+n)×Thick

So, we have:

h(n) = (5 + n) \times 1.52h(n)=(5+n)×1.52

h(n) = 7.6 + 1.52nh(n)=7.6+1.52n

When n = 0;

h(0) = 7.6 + 1.52 \times = 7.6h(0)=7.6+1.52×=7.6

When n = 1;

h(1) = 7.6 + 1.52 \times 1 = 9.12h(1)=7.6+1.52×1=9.12

When n = 2

h(2) = 7.6 + 1.52 \times 2= 10.64h(2)=7.6+1.52×2=10.64

When n = 3

h(2) = 7.6 + 1.52 \times 3= 12.16h(2)=7.6+1.52×3=12.16

Based on the information, the option that is a factor of x³ - 1331 is A. x - 11.

It should be noted that factor simply means the number that divides another number. In contrast to multiples, which are multiplied by another number to produce particular numbers, factors are the numbers that split the supplied number exactly.

It should be noted that when we factor out 1331, we will get the values of 11 × 11 × 11. Therefore, it should be noted that the expression will become x³ - 11³.

Therefore, it should be noted that the formula that will be applied will be:

a³ - b³ = (a - b)(a² + an + b²)

Therefore, applying the formula illustrated will give:

x³ - 11³

= (x - 11)(x² + 11x + 11²)

Polynomial expressions are mathematical statements that are represented by variables, coefficients and operators

The given parameters are

The sum of multiplicities of the polynomial equation must be equal to the degree.

This means that the multiplicity of each zero is 1

The equation of the polynomial is then calculated as

P(x) = Coefficient * (x - zero)^ multiplicity

So, we have

P(x) = -12(x - (-3))(x - (-1))(x - 2)

This gives

P(x) = -12(x + 3))(x + 1)(x - 2)

Step-by-step explanation:

The depreciation for the first year of the truck's useful life is $32,000.

The cost of the truck is $40000.

The useful time is 5 years.

The residual value is $5000.

Now, the depreciation is given as:

SLM depreciation = (Cost - Residual Value) / 5 years

Depreciation expense per year = ($40,000 - $5,000) / 5

Depreciation expense for the first year = $7,000

Now,

The depreciation expense per mile is the difference between cost and residual value divided by expected miles over the truck's life.

Depreciation expense per mile = (Cost - Residual Value) / Expected miles over truck's life.

Depreciation expense = Depreciation expense per mile × Miles driven

Therefore,

Depreciation expense per mile will be:

= ($40,000 - $5,000) / 15,000 miles = $2.33 or $2

The first year depreciation will be:
