3x²-x+1 is a factor of ax⁴+bx³+12x² - 6x + 1 . Then a-b equals​

Answers

Answer:

a-b = 31     (a ≠ b)

Step-by-step explanation:

(3x²-x+1)(px²+qx+1) = ax⁴+bx³+12x² - 6x + 1

3px⁴+(3q-p)x³+(3+p-q)x²+(q-1)x+1 = ax⁴+bx³+12x² - 6x + 1

q-1 = -6             q = -5

3+p-q = 3+p-(-5) = 8+p = 12             p = 4

b = 3q-p = 3*(-5) - 4 = -19

a = 3p = 3*4 = 12

a-b = 12 - (-19) = 31

If 2 angles in a triangle are 71 degrees and 56 degree, what is the measure of the third angle?

Answers

Answer:

53

Step-by-step explanation:

Sol'n

Let the remaining angle of a triangle be x.

x+71+56=180 (Sum of angles of a triangle is 180°)

Herman and his dad are leaving early in the morning for his lacrosse tournament. Their house is 210 miles from the tournament. They plan to stop and eat after 2 hours of driving, then compete the rest of the trip. Herman's dad plans to drive at an average speed of 60 miles per hour. How long will the second part of the trip take

Answers

The second part of the trip took 1.5 hours.

Average Speed is the ratio of the total distance travelled to the total time taken to cover that distance. It is given by:

Average Speed = total distance ÷ total time

Given that the distance from the house to the tournament is 210 miles, hence:

Total distance = 210 miles

Also, The journey was in two parts, the first part took 2 hours. Let the second part take t hours. Therefore:

Total time = t + 2

The average speed of 60 miles per hour, hence:

60 = 210 ÷ (t + 2)

60(t + 2) = 210

60t + 120 = 210

60t = 90

t = 1.5 hours

Therefore the second part of the trip took 1.5 hours.

0.8% of 150 is what numbers and how do you write the equation with a variable in it.

Answers

Answer:

1.2

Step-by-step explanation:

1. First, we have to write an equation with a variable! Given 0.8%, we know that it's equal to (0.8/100), and "of" means to multiply. Therefore, the equation will looks like this: [tex]\frac{0.8}{100} * 150 = x[/tex]

2. Now, let's solve for x!

[tex]\frac{0.8}{100} * 150 = (0.008)(150)[/tex] [tex](0.008)(150) = \frac{6}{5}[/tex] [tex]\frac{6}{5} = 1\frac{1}{5}[/tex] [tex]1\frac{1}{5} = 1.2[/tex] [tex]1.2[/tex]

Therefore, 0.8% of 150 is 1.2!

A factory uses 220,000 gallons of water to produce
2 tons of steel. How many gallons of water are
needed to produce 1 pound of steel?


A 55 gallons
B 110 gallon
C 110,000 gallon
D 440,000 gallon

Answers

2 tons = 4,000 pounds

So, 220,000 gallons of water is used to produce 4,000 pounds of steel.

4,000 pounds = 220,000 gallons

Divide both sides by 4,000 to get:

1 pound = 55 gallons.

So the correct answer is A.

In class today, we had 98 notebooks and 70 children.If each child gets two notebooks, how many more notebooks will we need?

Answers

Answer:

42

Step-by-step explanation:

times 70 by two to get how many notebooks needed total.

70*2=140

subtract how many notebooks you already had.

140-98=42

The no. of notebooks we need more will be equal to 42 notebooks.

It is given that no. of notebooks available is 98 and there are 70 children in class.

We have to find no. of notebooks needed more if each child gets two notebooks.

What is algebra ?

Algebra is the branch of mathematics that deals with various symbols and the arithmetic operations and the symbols are called variables.

As per the question ;

No. of notebooks we had in class = 98 notebooks

And

Total no. of children = 70 children

The no. of notebook each child gets = 2 per child

So ;

70 children will get no. of notebooks ;

= 70 × 2

= 140 notebooks

The no. of notebooks we need will be ;

= 140 - 98

= 42 notebooks

Thus , the no. of notebooks we need will be equal to 42 notebooks.

9 to the power 18 = 27 to the power x work out the value of x

Answers

Answer:

Step-by-step explanation:

27^x = 9÷(3^x)

So (3^3)^x = (3^2)÷(3^x)

So 3^3x = 3^(2-x)

Comparing powers on both sides,

3x = 2 - x

So, 4x = 2

So, x = 1/2

Given ( 27 ) ^ x = 9 / 3 ^x

⇒ ( 3 × 3 × 3 )^x = ( 3 × 3 ) / 3^x

⇒ ( 3 ³ )^x = 3² / 3^x

⇒  3 ^ 3x × 3^x = 3²            [ since  ( a ^m)^n = a ^mn ]

⇒ 3^ (3x +x) = 3²                [ since a^m × a^n = a ^m+n ]

⇒ 3^4x = 3²

⇒4x = 2                      [ since  If a ^m = a ^n then m = n ]

⇒ x = 2 / 4

 ∴ x = 1 / 2

I hope this helps you.

13

Step-by-step explanation:

So the concept is that co-interior angles add up to 180 in parallel line. This means:

3x + 9 + 9x + 15 = 180

So we solve for x.

12x + 24 = 180 ( What I did was simplifying the equation).

12x + 24 - 24 = 180 - 24

12x / 12= 156 / 12
