We know that two lines are parallel if they have the same slope. So we first find the slope of the given line. One way to do this is to rewrite the equation in its slope-intercept form, solving for y:

Then, we have:

Now, we have the slope and a point through which the line passes:

Then, we can use the point-slope formula:

The above equation is the equation of the line in its point-slope form. However, we can also rewrite the equation of the line in its standard form by solving for the constant:

Therefore, an equation of the line that passes through the point (-5,2) and is parallel to the line 4x - 5y = 5 is

First, we convert the 210 pounds to kilograms as the dose is given in mg per kg.

Recall that:

Therefore:

The dose call for 330 mg per kg, therefore, to get the dose for 95.2544 kg, we multiply by 95.2544:

Finally, dividing by 4 we get the dose the person should receive every 6 hours:

A = 20000

R = 5/100 = 0.05

T = 4

Thus, the value of x is 15 units

We can calculate the percent of the price that is excise tax by dividing the amount of tax per gallon by the final price of the gallon.

If the tax is 0.16 per gallon and the final price is 1.25 per gallon, the percentage can be calculated as:

The percentage that is city excise tax is 12.8% of the final price of the gasoline.

The value of the expression 0.3(1/4 - 1) + 0.35 is 0.125

The expression is

0.3(1/4 - 1) + 0.35

The expression is defined as the sentence with a minimum of two variables and at least one math operation.

Here the expression is

0.3 (1/4 - 1) + 0.35

First do the arithmetic operation in the bracket

0.3(1/4 - 1) + 0.35 = 0.3 × -0.75 + 0.35

In next step do the multiplication

0.3 × -0.75 + 0.35 = -0.225 + 0.35

Do the addition of the numbers

-0.225 + 0.35 = 0.125

Hence, the value of the expression 0.3(1/4 - 1) + 0.35 is 0.125

The value of tan(R) in the right triangle PQR where Perpendicular=QP, Base=RQ, Tan R=P/B. The slope of a straight line is the tangent of the angle made by the line with the positive x-axis.

Two geometric objects are perpendicular in simple geometry if they intersect at a right angle. The perpendicular symbol,⟂, can be used to graphically represent the condition of perpendicularity. It can be defined between two planes, two lines, or two planes and another line.

The base of a right angle triangle is the side on which it is positioned. The calculation can also be done using any of the two sides other than the hypotenuse as the base. It is the side of the right-angled triangle that is perpendicular to its base.

here,

Perpendicular=QP

Base=RQ

Tan R=P/B

=QP/RQ

Tan R=6/8

The perpendicular QP, base RQ, and tan's (R) values in the right triangle PQR. Tan's (R) = P/B. The tangent of the angle formed by the line with the positive x-axis is what determines a line's slope.

We have to calculate the height of the stack of hay bales.

We can start by calculating the volume as the number of bales times the volume of one hay:

Now, we know that this volume will be the area of the base times the height.

The area of the base can be calculated as the product of the length and the width:

We then can calculate the height as the volume divided by the base area:

Answer the height is 16 feet.

We can write a system of equations that describe our problem.

Since we don't know how the original $100,000 was divided, we call the two parts X and Y

So we know that X + Y = 100000

Then we know the Combined Interest coming from the accounts.

We use the Interest formula for return on investment:

I = P * r * t

were P is the principal, r is the percent rate (in decimal form), and t is the number of years (in our case 1)

Then the interest from the 3% account (let's call it I1) (if X amount of money was deposited there) is:

I1 = X * 0.03 * 1 = 0.03 X

Similarly, the interest I2 coming from the 1% account (if Y amount of money was deposited there) is given by:

I2 = Y * 0.01 * 1 = 0.01 Y

Then, the addition of these two interest is our total return of $1800:

0.03 X + 0.01 Y = 1800

Then our system of equations is:

X + Y = 100000

0.03 X + 0.01 Y = 1800

which we solve by substituting for example for Y in the first equation:

Y = 100000 - X

and replacing the Y by this expression in our second equation:

0.03 X + 0.01 (100000 - X) = 1800

use distributive property to eliminate parenthesis:

0.03 X + 1000 - 0.01 X = 1800

combine like terms

0.02 X + 1000 = 1800

subtract 1000 from both sides

0.02 X = 800

divide both sides by 0.02 to completely isolate X:

X = 800 / 0.02

X = $40000

This is the amount deposited on the 3% account

Then we easily calculate the amount deposited in the other account by replacing x with $40000 in the equation we use for substitution:

Y = $100000 - $40000 = $60000

Then, the amount deposited in the 1% account was $60000

and the amount deposited in the 3% account was $40000.

Solution:

Given the inequality below
