Adidea Corp regularly buts merchandise from vendors. It just purchased 1,000 units on credit from one of its vendors. How will the company record this transaction

Answers

Answer:

You did not include the price they bought the units at.

I will assume this price is $5.

find the smaller number of two consecutive odd numbers such that the sum of the larger numbers and twice the smaller number is 27 less than four times the smaller number​

Answers

Answer: 29

Step-by-step explanation:

Let the smaller number be x

Let the bigger number be x+2

The information given in the question can be represented in a equation as:

x + 2 + 2x = 4x - 27

3x + 2 = 4x - 27

4x - 3x = 27 + 2

x = 29

The smaller number is 29

Order from least to greatest. 41/50, .83, 80%

Answers

Answer:

Step-by-step explanation:

Ok so if we turn these all to frections with a denominator of 100 we will have

82/100, 83/100, and 80/100. So it will be 80%, 41/50, 0.83.

Answer:

80%, 41/50, 0.83.

___________________________

Showing Work

Using the given inputs:

41/50 83 80%

Rewriting these inputs as decimals:

41/50 83 80%

0.82 83 0.8

Sorting this table by decimal values in order from least to greatest:

80%   41/50   83

0.8 < 0.82 < 83

Therefore, the sorted inputs in order from least to greatest is:

80% < 41/50 < 83

An online company clothing company sells custom sweatshirts. The company charges $6.50 for each sweatshirt and a flat fee of $3.99 for shipping. Write a linear function in the form `y=mx+b`that represents the total cost, y, in dollars, for a single order of x sweatshirts.

Answers

Answer:

y = 6.5x + 3.99

Step-by-step explanation:

Let

Total cost = y

Single order of sweatshirts = x

Each sweat shirt = $6.50

We are given the linear function =

y = mx + b

Hence:

y = $6.50 × x + $3.99

y = 6.5x + 3.99

Therefore, the linear function in the form y=mx+b that represents the total cost is given as:

y = 6.5x + 3.99

the length of the hypotenus of a certain right triangle is 50 inches and the length of its legs is 40 inches . what is the length in inches of the other leg of the triangle

Answers

Answer:

The length of the other leg of the triangle is 30 inches.

Step-by-step explanation:

Pythagorean: a^2+b^2=c^2

50=hypotenuse

50^2-40^2=missing leg

50^2=2500

40^2=1600

50^2-40^2=900

[tex]\sqrt{900}[/tex]=30

30 is missing leg

The length of the other leg of the triangle is; 30 inches.

What is the right triangle?

A right-angle triangle is a triangle that has a side opposite to the right angle the largest side and is referred to as the hypotenuse. The angle of a right angle is always 90 degrees.

We have been given that the length of the hypotenuse of a certain right triangle is 50 inches and the length of its legs is 40 inches.

Using Pythagorean:

[tex]a^2+b^2=c^2[/tex]

50 = hypotenuse

Let the missing length is x.

x² = 50^2-40^2

x² = 2500 - 1600

x²  = 900

x =30

Hence, the length in inches of the other leg of the triangle is 30.

An online clothing company sells custom sweatshirts. The company charges
$5.50 for shipping plus $8.00 for each sweatshirt. Write a linear function rule that models the total
costy (in dollars) for any number of sweatshirts x

Answers

Well, the equation for this problem is 5.50x + 8.00.
The y-intercept / initial value in the problem is $5.50 because that is what you have to pay and it’s basically your initial value whereas $8.00 is your slope or rate if change because that is why you have $8.00x which means that whatever number of sweatshirts you buy, they will each cost you $8.00.

In degree measure, the angles pie/3, pie/4, and pie/2 are respectively

Answers

Answers:

pi/3 radians = 60 degreespi/4 radians = 45 degreespi/2 radians = 90 degrees

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

Explanation:

To apply the conversion, we use the idea that pi radians is equivalent to 180 degrees

pi radians = 180 degrees

To convert from radians to degrees, we'll multiply by the conversion factor (180/pi)

This leads us to the following:

(pi/3 radians)*(180/pi) = (pi*180)/(3*pi) = 180/3 = 60. So pi/3 radians converts to 60 degrees(pi/4 radians)*(180/pi) = (pi*180)/(4*pi) = 180/4 = 45. So pi/4 radians converts to 45 degrees(pi/2 radians)*(180/pi) = (pi*180)/(2*pi) = 180/2 = 90. So pi/2 radians converts to 90 degrees
