In order to make 441 liters of Petrolyn oil, we need 189 liters of synthetic oil.

Given, for every 3 liters of synthetic oil, we use 4 liters of natural oil.

⇒ For 1 liter of synthetic oil, we will be adding 4/3 liters of natural oil.

Let 'x' be the liters of oil needed to make 441 liters of Petrolyn oil

⇒ For 'x' liters of synthetic oil, we will need 4x/3 liters of natural oil

Total Volume = 441 liters

Volume of Synthetic oil + Volume of natural oil = 441

x + 4x/3 = 441

⇒ (3x + 4x)/3 = 441

⇒ 7x/3 = 441

⇒ x = (441×3)/7

⇒ x = 189 liters

The annual premium of Susie's insurance company apply as a result of accident is $255 for an year. This is because the monthly insurance payment has been increased by $21.25.

What is Health insurance?

Health insurance or the medical insurance is an insurance which covers the whole or a part of the risk of a person which is incurring the medical expenses. Depending upon the health insurance plan, the risk is shared among many individuals.

Main body:

The increase in monthly insurance payment = $21.25

So, the annual increase in the premium amount paid by Susie will be:

Monthly increase in insurance payment × 12

(As there are 12 months in an year)

Annual increase in premium amount = $21.25 × 12

Annual increase in premium amount = $255

Therefore, the annual increase in the amount of premium paid by Susie for health insurance is $225.

The equation of slope intercept form is  y =−4x+24

An intercept is a y-axis point through which the slope of a line passes. It is the y-coordinate of a y-axis point at which a straight line or a curve intersects. This is represented by the straight-line equation y = mx+c, where m is the slope and c is the y-intercept.

Given m = -4 and point)-3, -12)

One way to write a line's equation is in slope-intercept form, which looks like this:

y = mx+b

m = slope

b = y-intercept (where the line crosses the y-axis)

The problem has already been given

m = −4

x=-3

y=-12

Normally, the equation of a line is left with x and y being variables, and m and b having values. Since we do not have a value for b, we will plug all those numbers in and solve.

When those are substituted, the equation should look like this.

-12=(4)(-3)+b

-12=12+b

24=b

So the line's equation would be:

y=−4x+24

And this is your equation graphed. Notice how the line crosses the y-axis at 24, and that the slope is −4, just like the equation says.

Based on the given parameters, the amount owed is $10865

The given parameters about the compound interest are

Principal Amount, P = $5300

Interest Rate, R = 8%

Time, t = 6 years

To calculate the amount owed, we make use of the following formula

A = P + CI

Where

Compound interest, CI = P(1 + R)^t - P

So, the equation becomes

A = P + P(1 + R)^t - P

Evaluate the like terms

A = P(1 + R)^t

In this question, the formula is given as

A = P(1 + r/n)^nt

Where

n = 12, i.e compounded monthly

Substitute the known values in the above equation

A = 5300 * (1 + 8%/12)^(6*12)

Express 8% as decimal

A = 5300 * (1 + 0.08/12)^(6*12)

Evaluate the sum

A = 5300 * (1.01)^(6*12)

Evaluate the exponent

A = 5300 * 2.05

Evaluate the product

A = 10865

Hence, the value of the amount after 6 years is $10865

We know that the equation of the line passing through the points (x₁ , y₁) and slope " m " is given by

(y - y₁) = m(x - x₁)

So ,equation of line in "point slope form" is

(y - 15) = (-1)(x -(-12))

y - 15 = -1(x + 12)

y - 15 = -x - 12

y = -x - 12 + 15

Let event A: the sum of the spots on the up-faces is 7

We have 1+6, 2+5, 3+4, 4+3, 5+2, 6+1

There are 6 ways for this to happen. so,

Answer: f(0)=11/2

f(n) = f(n - 1) · (-2)

Step-by-step explanation:

f(0)=f(1)*(f(0+1)/f(1+1))

f(0)=f(1)*(f(1)/f(2))

f(0)=-11*(-11/22)

f(0)=-11*(-1/2) ==> -11/22 simplifies to -1/2

f(0)=-11*(-1)/2

f(0)=11/2

f(n) = f(n - 1) · f(2)/f(2-1)

f(n) = f(n - 1) · f(2)/f(1)

f(n) = f(n - 1) · 22/(-11)

f(n) = f(n - 1) · 2/(-1)

f(n) = f(n - 1) · (-2)

[tex]\frac{3}{4} < \frac{33}{40}[/tex]

Explanation:

[tex]\frac{3}{4}[/tex] (< = >) [tex]\frac{33}{40}[/tex]

To figure this out, you want both fractions to have the same denominator. So, you would find the GCF (Greatest Common Factor).

The GCF for 4 and 40 would be 40 because 4 * 10 = 40 and 40 * 1 = 40.

To make the whole fraction have the denominator 40, you have to multiply the numerator and the denominator by 10.

[tex]\frac{3}{4} = \frac{30}{40}[/tex]

So,

[tex]\frac{30}{40} < \frac{33}{40}[/tex]

or

No, they cannot construct a cube from the square pieces of foam board.

A square has four equal sides. When we multiply the length and width of a square to determine its area, we are essentially squaring one of its sides because they are the same.

A=s²

If we already know the area, we can work backward and take the square root to find the side:

√169=√s²

13=s

13 inches is the side length.

The length, breadth, and height of a cube are all equal. These three measurements are multiplied to determine a cube's volume; since they are equal, this essentially equals cubing the side length:

V=s³

The volume is 1728, so we have the following:

1728=s³

We take the cubed root and move backwards:

∛1728=∛s³
