Answer:

[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:

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

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)

                = 4(x² -2²)

                = 4(x + 4)(x-4)

3) 9x² -1 = 3²x² - 1² = (3x)² - 1²

             =(3x + 1)(3x - 1)

Answer: $4000 + $200n + $50x

Step-by-step explanation:

From the question, we are informed that every month, Rachel gets a basic salary of $4000 and also get a bonus of $200 for each policy she sells and a bonus of $50 for each client's complaint she resolves.

The expression for her total salary for a month if she sells n policies and resolves x complaints will be:

= $4000 + ($200 × n) + ($50 × x)

= $4000 + $200n + $50x

Answer:

x = 8

Step-by-step explanation:

Solve for x:

x/4 = 12/6

Hint: | Reduce 12/6 to lowest terms. Start by finding the GCD of 12 and 6.

The gcd of 12 and 6 is 6, so 12/6 = (6×2)/(6×1) = 6/6×2 = 2:

x/4 = 2

Hint: | Multiply both sides by a constant to simplify the equation.

Multiply both sides of x/4 = 2 by 4:

(4 x)/4 = 4×2

Hint: | Cancel common terms in the numerator and denominator of (4 x)/4.

(4 x)/4 = 4/4×x = x:

x = 4×2

Hint: | Multiply 4 and 2 together.

4×2 = 8:

Answer: x = 8

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:

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:

1.2, 3/5, 25%, 0.17, -12

Step-by-step explanation:

In order to put these from greatest to least, you must put these in like terms.

Since there are more decimals that other terms, we're going to convert them all to decimals.

25%= 0.25

0.17= 0.17

3/5= 0.60

1.2= 1.20

-12= -12.00

Now that we see which numbers are greater, we convert them back to their original terms and place them in order from greatest to least.

1.2, 3/5, 25%, 0.17, -12

Answer:

no solution

Step-by-step explanation:

Given

2(x + 1) = 2x + 5 ← distribute parenthesis on left side

2x + 1 = 2x + 5 ( subtract 1 from both sides )

2x = 2x + 4 ( subtract 2x from both sides )

0 = 4 ← not possible

This indicates the equation has no solution

Answer:

See below

Step-by-step explanation:

● 2(x+1) = 2x +5

Multiply 2 by (x+1)

● 2x + 1×2 = 2x+5

● 2x + 2 = 2x+5

Substract 2x from both sides

● 2x+2-2x = 2x+5-2x

● 2 = 5

This is impossible, so this equation has no solution.

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.

Answer:

1.18 times

Step-by-step explanation:

Given that :

Surface area of Lake Victoria = 26,828 sq miles

How much larger is the surface area of lake superior than that of like Victoria?

The surface area of Lake Superior = 31,700 sq miles

Hence, taking the ratio of the surface area of the two Lakes :

Lake Superior / Lake Victoria

31,700 / 26,828

= 1.1816013

Hence, the surface area of Lake Superior is 1.18 times larger than the surface area of Lake Victoria.
