The liters of synthetic oil that are needed is 456 liters.

From the information, petrolyn motor oil is a combination of natural oil and synthetic oil. It contains 5 liters of natural oil for every 6 liters of synthetic oil.

To make 836 liters of oil, the liters of synthetic oil will be:

= 6 / (6+5) × 836

= 6/11 × 836

= 456

Therefore, 456 liters are needed.

Round 492 to 500, then estimate 500/50

The nth-degree polynomial that satisfies the aforementioned conditions is the polynomial p (x) = -3 (x + 9) (x - 1 - 6i) (x - 1 + 6i).

Given that:

p is of degree 3.

1 + 6i and -9 are zeros of p.

Since 1 + 6i is an imaginary number equal to zero so 1 - 6i must also be the one equal to zero.

So, p (x) = A (x + 9) (x - (1 + 6i)) (x- (1-6i))

p (x) = A (x + 9) (x - 1 - 6i) (x - 1 + 6i) ........ (Z)

Using formula:

(a-b) (a+b) = a² - b²

(a-b)² = a² - 2ab + b²

Assume, x - 1 = a, 6i = b  

p (x) = A (x + 9) (x² - 2x + 1 + 36)

As i² = -1

p (x) = A (x + 9) (x² - 2x + 37)

Solving this equation we get,

p (x) = A (x³ - 2x² + 37x + 9x² - 18x + 333)

p (x) = A (x³ + 7x² + 19x + 333) ....... (1)

Given that:

p(2) = -1221

Putting the value of x = 2 and p(2) = -1221 in equation (1).

p(2) = A (2³ + 7(2²) + 19(2) + 333)

=> -1221 = A (8 + 28 + 38 + 333)

=> A = -1221/407

=> A = -3

Putting the value of A = -3 in equation (Z).

Hence, the polynomial p (x) = -3 (x + 9) (x - 1 - 6i) (x - 1 + 6i).

Answer:

d. If corresponding angles are congruent, then the lines are parallel

Step-by-step explanation:

This is an example of two lines intersected by a transversal. If corresponding angles on both lines are equal, then the lines must be parallel! Think about it! If both of the two-mark angles were 30 degrees, both lines would be pointing in the exact same direction - parallel!

If corresponding angles are congruent, then the lines are parallel thus option (d) is correct.

Two lines in the same plane that are equally spaced apart and never cross each other are said two lines in the same plane that are equally spaced apart and never cross each other to be parallel lines.

As per the given two parallel lines and one transversal.

The angle with a single mark is collectively known as the corresponding angle.

If the corresponding angle is the same insure that both lines which intersect at single lines will be parallel.

Hence "If corresponding angles are congruent, then the lines are parallel".

The discount rate used in calculator wound be 4.56%.

Given that,

You anticipate getting a bonus of $10000 after five years on the job.

We have the result of your calculation for the parent value of this bonus is $8000. what percentage of a discount rate did you use.

We know that to find the present value of a future sum of money .

PV= FV/(1+r)ⁿ

Here,

PV is present value = $8000

FV is future value = $10000

r is discount rate we have to find

n is time = 5 years

Substitute in the formula,

$8000=$10000/(1+r)⁵

(1+r)⁵=$10000/$8000

(1+r)⁵=1.25

Answer:

Step-by-step explanation:

so what is the difference from 1/4 to 5/8 ?   is the question

2/8=1/4

5/8-2/8 = 3/8

9 gallons of fuel fill 3/8 of the tank

since 3/8 is 9 gallons we can see that 1/8 will be 3 gallons or 9/3=3

then multiply 3 gallons by the 8 parts for the whole tank

3*8=24 gallons.

Than tank can hold 24 gallons

It will take the word processor 165 minutes to check 22 pages

The given parameters in the question are:

Speed = 30 minuter per 4 pages

Number of pages = 22 pages

The number of hours to check the pages can be calculated using the following equation

Time = Speed * Number of pages

Substitute the known values in the above equation So, we have the following equation

Time = 30/4 * 22

There is no unit to convert

So, we have

Time = 30/4 * 22

The passenger train traveling at 30 mi/hr faster than the freight train and traveling 3 times the distance traveled by the freight train, through the kinematic equations, indicates that the speed of the freight train is 15 mi/hr and the speed of the passenger train is 45 mi/hr.

Kinematics is the study of the motion of an object without reference to the force that causes the motion.

The speed of the passenger train = 30 + The speed of the freight train

Distance traveled by the passenger train in 6 hours = 3 × The distance traveled by the freight train

Let v represent the speed of the freight train and let d represent the distance traveled by the freight train in 6 hours

From kinematic equations, we get;

Speed of the passenger train = 30 + v

Distance traveled by the passenger train in 6 hours = 3 × d

(30 + v) × 6 = 3•d

6•v = d

Which gives; (30 + v) × 6 = 3 × 6•v

180 + 6•v = 18•v

12•v = 180

v = 180 ÷ 12 = 15

The speed of the freight train is v = 15 mi/hr

The speed of the passenger train = 30 + v

The speed of the passenger train is (30 + 15) mi/hr = 45 mi/hr

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

The total cost of the parts is = $ 141

The total number of hours worked by the technician = 4.25 hours

The total cost of repair = $ 332.25

Let the cost of the labor be = y

The total cost of labor =
Cost of the labor per hour x Number of hours worked by the technician

The total cost of labor = 4.25y

Now ,

The total cost of repairing the computer =
Total cost of labor  + Total cost of the parts

The total cost of repairing the computer = 141 + 4.25y

332.25 = 141 + 4.25y

Subtracting 141 on both sides , we get

4.25 y = 191.25

Divide by 4.25 on both sides , we get

y = $ 45

Therefore cost of labor per hour y = $ 45

Hence , the total cost of labor per hour is $ 45

Answer: 29, 36, 38

Step-by-step explanation:

The sequence starts with 2 and proceeds to go to 9, which is a difference of 7.

After 9 it is 11, and the difference is 2.

After 11 it is 18 which is a difference of 7 again.

The pattern is difference of 7, difference of 2.

Since there was a difference of 7 between 20 and 27, the next difference will be 2, which is 29.

So, the pattern is +2, +7, +2 . . .

Therefore, your next three numbers will be 29, 36, 38
