Answer:

Step-by-step explanation:

a² - b² = (a + b) (a - b)

1)x² - 36 = x² - 6² = (x + 6)(x-6)

2) 4x² - 16 = 4x² - 4*4 = 4(x² - 4)

Answer:

You have 3 pennies and your friend has 1 penny

Step-by-step explanation:

The given parameters are;

Let friend A = you

friend B = Your friend

The number of pennies with  friend A when he gives friend B 1 penny = Equal number of pennies between friend A and B

The number of pennies with friend A when he is given 1 penny by friend B = 2 times the number of pennies with friend B

Let the number of pennies with friend A = X and the number of pennies with friend B = Y, therefore, we have;

X - 1 = Y + 1.....................(1)

X + 1 = 2 × Y...................(2)

Subtracting equation (1) from equation (2), we get;

X + 1 - (X - 1) = 2·Y - (Y - 1)

X - X + 1 + 1  = 2·Y - Y + 1

2 = Y + 1

Y = 2 - 1 = 1

Y = 1

From equation (1), X - 1 = Y + 1 gives;

X - 1 = 1 + 1

X = 1 + 1 + 1 = 3

Friend A has 3 pennies and friend B has 1 penny.

Therefore, you have 3 pennies and your friend has 1 penny

Step-by-step explanation:

It is given that, three oil tankers together contain 37 5/7 litres of oil.

Total volume of oil is [tex]\dfrac{264}{7}\ L[/tex]

If two tankers have 11 3/14 litres and 12 3/7 litres of oil.

Oil in first tanker is [tex]\dfrac{157}{14}\ L[/tex]

Oil in second tanker is [tex]\dfrac{87}{7}\ L[/tex]

Oil in first and second tanker is :

[tex]\dfrac{157}{14}\ L+\dfrac{87}{7}\ L=\dfrac{331}{14}\ L[/tex]

Noo, oil in the third tanker = total volume - (Oil in first tanker + second tanker )

Option (4) is correct.

Answer:

10^4

Step-by-step explanation:

lets say the number is 1.0 if you where to move the decimal to the right 4 place the number would then be 10,000.0. basically if it says 10^4 add 4 0's

Moving the decimal point to the right 4 places in a number is the same as multiplying by 10⁻⁴.

The number system is a way to represent or express numbers.

A decimal number is a very common number that we use frequently.

Since the decimal number system employs ten digits from 0 to 9, it has a base of 10.

Any of the multiple sets of symbols and the guidelines for utilizing them to represent numbers are included in the Number System.

Let's consider a decimal number

2.23456 now multiply and divide by 10⁴

⇒ 2.23456 × 10⁴/10⁴

⇒ 22345.6/10⁴

⇒ 22345.6 × 10⁻⁴

Hence"Moving the decimal point to the right 4 places in a number is the same as multiplying by 10⁻⁴".

Answer:

The information that we have is:

"The graph of y=-1/2x+2 is positive over the interval negative infinity and 4 and negative over the interval 4 and infinity."

Now, i guess that the question is:

"What happens on the graph when x = 4 ?"

Well, if for values of x smaller than 4 the graph is negative and for values of x larger than 4 the graph is positive, this must that the graph must cross the x-axis at some point, then with only that information, we can conclude that the graph is equal to zero when x = 4.

But we could also test it with the equation:

y = -(1/2)*x + 2

if we replace the x by a 4.

y = -(1/2)*4 + 2 = -2 + 2 = 0.

Then our previous hypothesis was correct.

Answer: Choice C

[tex]y \ge 4x-5[/tex]

===============================================

Explanation:

First we need to find the equation of the boundary line. This is the line that separates the shaded region versus the non-shaded region.

The boundary line goes through (0,-5) so this is the y intercept, so b = -5

Another point on the boundary line is (1,-1). The slope of the line through (0,-5) and (1,-1) is m = 4. You can use the slope = rise/run idea or you could use the slope formula to get m = 4.

With m = 4 and b = -5, the y = mx+b equation updates to y = 4x-5

The boundary line has the equation y = 4x-5

Because it is a solid boundary line (instead of dashed) and the shading is above the boundary, this means we change the equal sign to "greater than or equal to"

Therefore we get [tex]y \ge 4x-5[/tex]

Note: a solid boundary line means that points on this boundary are included in the solution set. A dashed boundary line would mean you don't include boundary points in the solution set. So that's why there is a "or equal to" portion in the inequality sign.

[tex]\sqrt{91}[/tex]  is irrational

Step-by-step explanation:

A rational number is a number that can be written as a ratio. Any whole number is rational number because it can be turned into a ratio.

The [tex]\sqrt{91}[/tex] is irrational.  

3 (or 3/1) is rational.

3/4 is rational

[tex]\sqrt{64}[/tex] = 8 and thus, is rational.

[tex]\sqrt{91}[/tex] = 9.539392014...... and is irrational

10.25 can be written as 41/4 so it's also rational.

This is based on my assumption you mistyped the 2 with the commas.

Answer:

1. I= $36, NB = $336

2. R = 5%, NB = $517.50

3. T= 5 YEARS, NB = $612.50

4. P= $675, NB = $783

Step-by-step explanation:

1. p= 300, r=3% t=4year

I= p*r*t

i= 300 * (3/100) * 4

i = 300 * 0.03 * 4

i = 36

New Balance = 300+36 = $336

2. r = (i*100)/(p*t)

= (67.50*100)/(450*3)

= 6750/1350

= 5%

New Balance =450+67.50 = $517.50

3. t= (i*100)/(p*r)

= (112.50*100)/(500*4.5)

= 11250/2250

=5

New Balance = 500+112.50 =$612.50

4. p= (i*100)/(r*t)

= (108*100)/(8*2)

The correct answer is 367,244.

Number System is a method of representing Numbers on the Number Line with the help of a set of Symbols and rules. These symbols range from 0-9 and are termed as digits. Number System is used to perform mathematical computations ranging from great scientific calculations to calculations.

Positive Numbers: Numbers that are represented on the right side of the zero are termed as Positive Numbers. The value of these numbers increases on moving towards the right. Positive numbers are used for Addition between numbers. Example: 1, 2, 3, 4, …

Negative Numbers: Numbers that are represented on the left side of the zero are termed as Negative Numbers. The value of these numbers decreases on moving towards the left. Negative numbers are used for Subtraction between numbers. Example: -1, -2, -3, -4, …

as per the situation given,

we have number has a thousands digit that is ten times greater than the hundreds digit.

Answer : The value of 'x' is 8.

Step-by-step explanation :

As we are given that :

NO = 17

NP = 5x - 6

From the given diagram we conclude that NO and OP are equal and RO and OQ are equal. That means,

NO = OP and RO = OQ

That means,

NO = OP = 17

And we know that:

NP = NO + OP

So,

5x - 6 = 17 + 17

5x - 6 = 34

5x = 34 + 6

5x = 40

x = 8

Thus, the value of 'x' is 8.

Answer:

27°,63°

Step-by-step explanation:

Let the two angles be a and b.

They are complementary, meaning they add up to 90. Thus:

[tex]a+b=90[/tex]

And we are told their difference is 36. Therefore:

[tex]a-b=36[/tex]

Solve for the system of equations. Add b to both sides in the second equation:

[tex]a=b+36[/tex]

Substitute this into the first:

[tex](b+36)+b=90[/tex]

Combine like terms;

[tex]2b+36=90[/tex]

Subtract 36:

[tex]2b=54[/tex]

Divide by 2:

[tex]b=27[/tex]

So, b is 27 degrees.

Use the second equation again:

[tex]a-b=36[/tex]

Now that we know b is 27, substitute:

[tex]a-27=36[/tex]

Add 27 to both sides:

[tex]a=63[/tex]

So, a is 63 degrees.

And we're done :)

Answer:

27 and 63

Step-by-step explanation:

x - y = 36

x + y = 90

add the equations together

2x = 126

x = 63

substitute x for x in the first equation

63 - y = 36

y = 27
