Two equations that have the same solution as the given equation are;

2.3. p - 10.1 = 6.49. p - 4

230.p - 1010 = 650.p - 400 - p

The correct options are B and C.

The given equation is; 2.3·p - 10.1 = 6.5·p - 4 - 0.01·p

Simplifying the above equation by collecting like terms gives;

2.3·p - 10.1 = 6.5·p - 0.01·p - 4 = 6.49·p - 4

2.3·p - 10.1 = 6.49·p - 4

Both sides of an equation will remain equal, when both sides are multiplied by the same amount.

Multiplying both sides of the original equation by 100 gives the same solution as follows;

100 × (2.3·p - 10.1) = 100 × (6.5·p - 4 - 0.01·p)

Let x be the number of $1 bills and y be the number of $10 bills.

We know that:

x + y = 59 (the total number of bills)

x + 10y = 239 (the total monetary value of the bills)

We can use the first equation to solve for one of the variables in terms of the other. For example:

x = 59 - y

We can substitute this expression for x into the second equation:

(59 - y) + 10y = 239

59 + 9y = 239

9y = 180

y = 20 (the number of $10 bills)

We can use this value of y to find the number of $1 bills by substituting it back into the first equation:

x + y = 59

x + 20 = 59

x = 39 (the number of $1 bills)

Therefore, the motel clerk has 39 $1 bills and 20 $10 bills.

The total cost that he paid for the parking for 5 days is $26.00.

When an algebraic equation is graphed, it always results in a straight line since each term in a linear equation has an exponent of 1. For this reason, it is referred to as a "linear equation."

There are both one-variable and two-variable linear equations.

The graph above shows the cost of parking at the airport,

since the graph is a straight line so it is the condition for a linear equation,

from the graph, the y-axis shows the price in dollars and the x-axis shows the number of days,

line of the graph passes from coordinates (0, 6) and (6, 30)

equation of line is y = mx + c

where c is initial cost when x is 0, y is 6

c = 6

and m = (y₂- y₁)/(x₂ - x₁)

m = (30 - 6)/(6 - 0)

m = 4

equation of line is,

y = 4x + 6

cost for 5 days,

answer: In this case, -0.50, -0.10, 0.60, 0.68, 0.98 are all correlation coefficients and -0.50 is the least and 0.98 is the greatest among the given correlation coefficients.

but why? The correlation coefficients can be ordered from least to greatest as:

-0.50, -0.10, 0.60, 0.68, 0.98

A correlation coefficient is a measure of the strength and direction of a linear relationship between two variables. The value of the coefficient ranges from -1 to 1, where:

A coefficient of -1 represents a perfect negative correlation, meaning that as one variable increases, the other variable decreases.

A coefficient of 0 represents no correlation, meaning that there is no linear relationship between the two variables.

A coefficient of 1 represents a perfect positive correlation, meaning that as one variable increases, the other variable also increases.

Answer: As the loan is amortized, Boris will make a series of equal payments each month for the duration of the loan, with each payment comprising of both interest and principal. The amount of interest in each payment will decrease over time, while the amount of principal in each payment will increase.

To calculate the monthly payments, we can use the formula:

M = P [ i(1 + i)^n ] / [ (1 + i)^n - 1]

Where:

M = monthly payment

P = the principal or the loan amount = 91500

i = interest rate as a decimal = 3.3%/12 = 0.00275

n = total number of payments = 40 years x 12 months/year = 480

By substituting the values in the formula:

M = 91500 [ 0.00275 (1 + 0.00275)^480 ] / [ (1 + 0.00275)^480 - 1]

M = $439.65

So the monthly payment that Boris will make is $439.65. This amount will stay the same throughout the loan term, but the proportion of interest to principal in each payment will change as the loan is amortized.

The inequality equation for the given graph is option B: y ≤ 1/3x - 4.

What is an inequality?

In Algebra, an inequality is a mathematical statement that uses the inequality symbol to illustrate the relationship between two expressions. An inequality symbol has non-equal expressions on both sides. It indicates that the phrase on the left should be bigger or smaller than the expression on the right, or vice versa.

The given inequality equations are -

y ≥ 1/3x - 4

y ≤ 1/3x - 4

y ≤ 1/3x + 4

y ≥ 1/3x + 4

In a graph of an inequality, the symbols (<,>) are represented using a dotted line and the symbols (≤,≥) are represented using a straight line.

Now, write the inequality in equation form -

y = 1/3x - 4

y = 1/3x + 4

Substituting the values of x and y with origin (0,0) -

0 = 1/3(0) - 4

0 = -4

0 = 1/3(0) + 4

0 = 4

Putting the inequality symbol back -

y ≥ -4

This statement is false as seen in the graph.

y ≤ -4

This statement is true as seen in the graph.

y ≤ 4

This statement is false as seen in the graph.

y ≥ 4

This statement is false as seen in the graph.

Therefore, the equation for the graph is y ≤ 1/3x - 4.

83 in burn in 5 hours.

so, we have a 83/5 speed ratio.

directly proportional means

y = kx

with k being constant for all values of x.

83 = k×5 = 5k

k = 83/5

15 in burn in x hours.

therefore,

15 = 83/5 × x

75 = 83x

x = 75/83 hours

this can be also calculated like this :

because of the direct proportionality, 15/x must have the same ratio as the original 83/5.

83/5 = 15/x

83x/5 = 15

83x = 75

x = 75/83 hours = 0.903614458... hours

The rate of change of the angle of elevation is approximately - 2.597 degrees per second (-0.045 radians per second). (Correct choice: C)

In this problem we find the case of a drone that travels horizontally, at constant height (h), in meters. The rate of change of the angle of elevation (θ'), in degrees per second, can be found from trigonometric functions and derivatives:

tan θ = y / x

Where:

By derivatives:

sec² θ · θ' = - y · x⁻² · x'

θ' = - (y · x⁻² · x') / sec² θ

Where x' is the speed of the drone, in meters per second.

If we know that y = 5 m, θ = π / 6 and x' = 5 m / s, then the rate of change of the angle of elevation is:

x = y / tan θ

x = (5 m) / tan (π / 6)

x ≈ 2.887 m

θ' = - [(5 m) · (2.887 m)⁻² · (5 m / s)] / sec² (π / 6)

θ' ≈ - 2.597 degrees per second (- 0.045 radians per second)

a. The initial quantity of radioactive material is 0.68 g.

b. It will take an additional 7.15 years for the amount of radioactive material to reduce to 0.2 g.

a. In order to find the initial quality of radioactive material, we will use the formula:

Initial Quality = Final Quantity * (1 - Reduction Rate)^Years

We know that -

the final Quantity is 1.52 g, the reduction rate is 18% (or 0.18), and the number of years is 4.

Initial Quantity = 1.52 g * [tex](1 - 0.18)^4[/tex]

Initial Quantity = 1.52 g * 0.452

Initial Quantity = 0.68 g

Hence, the initial quantity of the radioactive material is 0.68 g.

b. In order to find how many more years it will take for the amount of radioactive material to reduce to 0.2 g, we will use the formula:

Years = log(Final Quality / Initial Quality) / log(1 - Reduction Rate)

We know that -

the final quality is 0.2 g, the initial quality is 0.68 g, and the reduction rate is 18% (or 0.18).

Years = log(0.2 / 0.0.68) / log(1 - 0.18)

Years = 7.15

The number is 7

Step-by-step explanation:

1. Create the equation needed to solve this

Lets think of a number as x. We have a number multiplied by 6 and have 4 added to it.

We get:

6x + 4

Now this sum is equal to the product of 2 and 23. We connect this to get

6x + 4 = 2(23)

We can simplify this to

6x + 4 = 46

2. Solve for x

6x + 4 = 46

Subtract 4 from both sides

6x = 42

Divide both sides by 6

x = 7

Therefore the number is 7
