47) A convention manager finds that she has $1370, made up of twenties and fifties. She has a total of 46 bills. How many fifty-dollar bills does the manager have?

Something can be described as a function if there is only 1 of each number in the input or x.

For example: (9,6) and (9,3) would not be a function because there are two 9’s as the input.

So, for this problem there are two 3’s meaning this is NOT function because there are two outputs for the same number.

Your answer is going to be D.

Answer:

The task is to calculate the total amount spent by Mr. Spendalot. To do this, you need to calculate the amount of inventory purchased, apply the discount, calculate the sales tax, and add the tip. Here's one way to do it:

Calculate the amount of inventory purchased: 31% of $1,000,000 is 31/100 * $1,000,000 = $310,000

Determine the discount: Based on the purchase amount of $310,000, Mr. Spendalot qualifies for a discount of 10%. So, the discount is $310,000 * 10% = $31,000.

Calculate the sales tax: 8.5% of the purchase amount after discount is 8.5/100 * ($310,000 - $31,000) = $2,067.50

Add the tip: 15% of the purchase amount after discount and sales tax is 15/100 * ($310,000 - $31,000 + $2,067.50) = $52,101.13

Calculate the total: The total amount spent by Mr. Spendalot is ($310,000 - $31,000 + $2,067.50 + $52,101.13) = $393,168.63.

So, the total amount spent by Mr. Spendalot is $393,168.63.

Step-by-step explanation:

Determine the amount of purchase before discount: Mr. Spendalot bought 31% of Mr. Shine's inventory, which is $1,000,000. Therefore, his purchase before discount is 31% of $1,000,000, or $310,000.

Calculate the discount: Based on the information in the discount table, Mr. Spendalot's purchase qualifies for a 40% discount. Therefore, the discount amount is $310,000 * 40%, or $124,000.

Determine the amount of purchase after discount: After getting the 40% discount, Mr. Spendalot's purchase is $310,000 - $124,000, or $186,000.

Calculate the sales tax: Mr. Shine charged an 8.5% sales tax on Mr. Spendalot's purchase after discount. Therefore, the sales tax amount is $186,000 * 8.5%, or $15,791.

Determine the tip: Mr. Spendalot gave Mr. Shine and his staff a 15% tip on his purchase after discount and sales tax. Therefore, the tip amount is $186,000 + $15,791 * 15%, or $31,328.

Calculate the total cost: Adding up the purchase after discount, sales tax, and tip, we get the total cost of $186,000 + $15,791 + $31,328, or $233,119.

Conclusion: Mr. Spendalot's total purchase cost is $233,119.

The task requires you to calculate the total amount spent by Mr. Spendalot at Mr. Shine's store Ice Box. Mr. Shine has an inventory worth $1,000,000 which he marks up by 150%. Mr. Spendalot bought 31% of this inventory, and was given a discount based on the amount he spent:

Spend 100k+ and get 10% off

Spend 250k+ and get 20% off

Spend 500k+ and get 30% off

Spend 750k+ and get 40% off

Spend 1 million+ and get 50% off

After the discount, Mr. Spendalot was charged 8.5% sales tax. He also left a 15% tip for Mr. Shine and his staff. Your goal is to calculate the total amount spent by Mr. Spendalot.

Answer:

9x² - 64 square yards

Step-by-step explanation:

Area of a rectangle is L x W where

L = length
W = width

Letting
L = 3x + 8
W = 3x - 8

L x W = (3x + 8)(3x-8)

Using the identity (z + b)(a - b) = a² - b²

with a = 3x, b = 8

(3x+8)(3x-8) = (3x)² - (8)²

= 9x² - 64 square yards

The estimated area of Laurens's circle is 642 squared.

A circle is a two-dimensional figure with a radius and circumference of 2πr.

The area of a circle is πr².

We have,

Parker:

Area = 40 squared

This means,

πr² = 40

r² = 40/3.14

r² = 12.74

r = √12.74

r = 3.6

Laurens:

r = 4 x 3.6

r = 14.3

Area = πr²

Area = 3.14 x 14.3 x 14.3

Area = 642

Thus,

Laurens's circle area is 642 squared.

well, we can simply find how much for each tulip in each store.

store left has them for £9.8 for 4, that means 9.8 / 4 = 2.45, so £2.45 for each tulip.

store right had them for £4.2 each, but they went down by 1/3, so hmm a whole is 3/3 so if we take away 1/3 from 3/3, 3/3 - 1/3 = 2/3, so the new discounted price is really 2/3 of £4.2, that's (2/3) * 4.2 = 2.8, so £2.8 each.

so store left has them cheaper, doesn't matter at a dozen or less or more.

It is proven that in given right angle triangles a² = cx.

The angles that are identical to each other are known as Congruent angles. The measure of these concurrent angles is always equal to each other.

They can be acute, obtuse, exterior, or interior angles because the congruence of angles is unaffected by the type of angle. As we know a right angle is 90° all right angles are congruent angles.

Here we have

Two right-angle triangles MOP and MNO

Measurements of Δ MNO side are a, b, and c is the hypotenuse    

Measurements of Δ MOP sides are a, x, and OP is the hypotenuse    

Here we need to prove that a² = c x  

We can prove its as follows

As we know all right angles are concurrent

Statement                            Reason

=> ∠NOM ≅ ∠OPM              [ ∵ right-angles are concurrent ]  

=> ∠OMN≅ ∠PMO               [ ∵ Common angle ]  

=> ΔMOP ~ ΔMNO                   [ By Angle - Angle - Angle criteria ]

Since ΔMOP ~ ΔMNO        

=> a/x = c/a                         [ ratio of the corresponding side ]

Now we multiply 2 * 6:

h(6) = 12 + 1

Now 12 + 1:

h(6) = 13, final answer.

Step-by-step explanation:

I just answered this.

the first group is consistent independent, because both equations are lines with different slope. so, they have 1 intersection, which is the solution.

the second group is consistent dependent, because both equations describe the same line.

multiply the second equation by -2, or divide the first equation by -2, and you see they are identical. multiplying an equation by a factor on both sides does not change the equation or function.

so, as both lines are identical, every point on the line is an intersection and solution. therefore, there are infinitely many solutions.

the third group is inconsistent.

they represent 2 lines with identical slope but different y-interceptions. so, they are parallel and have no intersection or solution at all.

just think : there is no pair of numbers x,y, for which their sum can have 2 different results.

The solution to the above problems are given as follows:

7) m∠A = 102°. m∠B = 102.°

8) ∠QSR = 59.6°

9) ∠ADC = 55°

7) Since both angles are vertical, it, therefore, means they are congruent. Ths,

4x + 6 = 7x-66; collect like terms

6+66 = 7x -4x

72 = 3x

x = 72/2

Thus,

x = 24

Plugging in the value of x back into the expressions, we have:

m∠A = 4x + 6

= 4(24) + 6

= 96+6

= 102°

Thus, m∠A = 102.

Since both angles are congruent, that means m∠B is also 102°

8) To find ∠QSR, we need to find x. Note that Angle on a Straight line sums up to 180°. Thus,

4x-8+34+72-x = 180

4x - 8 + 34 + 72 - x = 180

5x + 98 = 180

5x = 82

x = 16.4

So the solution is x = 16.4.

Since ∠QSR = 76-x

∠QSR = 76-16.4

Thus,

∠QSR = 59.6°

9) Applying the same rule (Angles on a straight line to the above problem, we can state that:

2x+1 + (x-7) = 180°;
To solve for x, we can simplify both sides of the equation and then isolate x:

2x + 1 + x - 7 = 180

3x - 6 = 180

3x = 186

x = 62

So the solution is x = 62.

Thus, ∠EDF = 62 - 7

= 55°

since  ∠EDF  and  ∠ADC are opposite angles, and opposite angles are congruent,

∠ADC = 55°

m∠H = x - 1

The sum of the angles of the triangle is 180 degrees.

m∠H + m∠I + m∠J = 180

(x - 1) + (2x + 5) + (7x + 6) = 180

x - 1 + 2x + 5 + 7x + 6 = 180

10x + 10 = 180

Take 10 common.
