Jasmine has 50 shares of a stock. The value of each share went down by $2 today. Express the total change in value of Jasmines shares as an integer calculation.

Answers

The change is Jasmine's stock is represented by -$100.

If each stock dropped by a value of $2 and she had 50 stocks, she had a 50 x $2 change. Because The stock dropped this is a negative change.
Answer:
The rate of change would, be -$100 where the negative sign expresses a decrease in the value of total share.

Explanation:
We are given that:
Jasmine has 50 shares
Value of each share decreased by $2

This means that:
Jasmine's total shares decreased by 50*2 = $100

The rate of change would, thus, be -$100 where the negative sign expresses a decrease.

last summer Marion was three and a half feet tall she was 4 inches taller than her brother Elijah she was one in a quarter feet shorter than her sister Lori how tall were Elijah and Lori Last Summer

Answers

Let M be Marion, L be Lori and E be Elijah.
M = 3.5 ft.
E = M - 4/12 (since he was 4 inches shorter than Marion) = 3 1/2 - 4/12; find a common denominator (12):  3 6/12 - 4/12 = 3 2/12 = 3 1/6 ft.
L = M + 1.25 (since she was 1 1/4 feet taller than Marion) = 3.5 + 1.25 = 4.75 feet.

Calculate the resistance of a piece of aluminum wire with a diameter of 100 mils and a length of two miles, at 68°F. Hint: Be sure to first convert mils to cmils and use the K value for aluminum found in the reference. (Round the FINAL answer to two decimal places.)

Answers

Final answer:

The resistance of the aluminum wire with a diameter of 100 mils and a length of two miles is 0.20 ohms.

Explanation:

To calculate the resistance of a piece of aluminum wire, we first need to convert the diameter from mils to cmils. 1 mil is equal to 1000 cmils. So, a diameter of 100 mils is equal to 100,000 cmils. Next, we need to use the K value for aluminum, which is 1.82 ohms * cmil/ft. We convert the length of the wire from miles to feet, which gives us 10560 feet. Now, we can calculate the resistance using the formula:

Resistance = (K * Length) / Area

Where K is the conductivity of aluminum, Length is the length of the wire in feet, and Area is the cross-sectional area of the wire in cmils. Plugging in the values, we get:

Resistance = (1.82 * 10560) / 100000 = 0.1957 ohms

Therefore, the resistance of the aluminum wire is 0.20 ohms.

The resistance of the aluminum wire with a diameter of 100 mils and a length of two miles, at 68°F, is 0.0002784 ohms.

To calculate the resistance of the aluminum wire, we need to convert the diameter from mils to cmils. 1 mil is equal to 1000 cmils.

So, the diameter of the wire in cmils would be 100 * 1000 = 100,000 cmils.

Next, we need to use the K value for aluminum, which is 2.65 micro-ohm cmil/foot. We need to convert the length of the wire from miles to feet. 1 mile is equal to 5280 feet.

So, the length of the wire in feet would be 2 * 5280 = 10,560 feet.

Now, we can calculate the resistance using the formula R = (K * L) / A, where R is the resistance, K is the K value for aluminum, L is the length of the wire in feet, and A is the cross-sectional area of the wire in cmils.

Plugging in the values, we get R = (2.65 * 10^(-6) * 10560) / 100000 = 0.0002784 ohms.

s = 2940/4
s = 735

M = 2*S

How are these four types of transformation similar to each other? How do they differ? In particular, what is one major difference between dilations and the other three types of transformations?

Answers

The four transformations:
Translation, Rotation, Reflection, and Scaling

Each of these transformations change how or where the shape is. Each of these transformations change the shape or shapes in different ways. Dilations change the size and sometimes even the shape of the shape; translation, rotation, and reflection just move the shape around they don't change the size or shape of it.

Is that what you are looking for? Let me know if there anything more...

Final answer:

Geometric transformations include translations, rotations, reflections, and dilations; while the first three preserve figure size and shape, dilations change the size of the figure by a scale factor.

Explanation:

Geometric transformations include translations, rotations, reflections, and dilations, all of which change a figure's position and/or size on the plane while maintaining the straightness of lines and parallelism where applicable. These transformations are similar in that they can be applied to geometric figures to alter their position or size within a coordinate system. A major difference between dilations and the other transformations is that dilations change the size of the figure but do not preserve angles and lengths in the same way as the others. A dilation either enlarges or shrinks a figure by a scale factor from a central point, while translations, rotations, and reflections do not alter the size of the figure, only its position or orientation.

What is the area of this figure ?

Answers

 Remember that what you must do for this case is to calculate the area of the parallelogram and add it to the area of the rectangle.
  Palelogram area:
  Knowing the base and the height, the area of the parallelogram is calculated by its formula: 
  A1 = b * h
  We have then
  b = root ((- 4 - (- 10)) ^ 2+ (2-2) ^ 2) = 6
  h = root ((- 7 - (- 7)) ^ 2+ (3-2) ^ 2) = 1
  A1 = (6) * (1) = 6 units ^ 2
  Rectangle area
  A2 = L * W
   We have then:
  L = root ((1 - (- 2)) ^ 2 + (- 3 - (- 4)) ^ 2) = 3.16227766
  W = root ((- 4 - (- 2)) ^ 2+ (2 - (- 4)) ^ 2) = 6.32455532
  A2 = (3.16227766) * (6.32455532)
  A2 = 20 units ^ 2
  The total area is the sum of both ares:
  A = A1 + A2
  A = 6 + 20
  A = 26 units ^ 2
  Answer:
  the area of this figure
  A = 26 units ^ 2

Kit bought a soft drink and a sandwich for $9.00. What was the price of each if the sandwich cost 3.5 times much as the soft drink?

Answers

Let the cost of the soft drink = C   then the price of the sandwich was 3.5 times as much = 3.5C

 

And

 

C + 3.5C  = Total Cost

 

C + 3.5C  =   9

 

4.5C = 9    divide both sides by 4.5

 

C = 9/4.5  =  $2.00   for the soft drink

 

And  3.5C = 3.5(2.00)  = $7.00   cost of the sandwich

If Kit bought a soft drink and a sandwich for $9.00 and the sandwich cost 3.5 times much as the soft drink the price of the sandwich and soft drinks will be $7.00 and $2.00 respectively.

What are arithmetic operations?

The study of numbers and their operations, which are relevant to all other fields of mathematics, is part of the discipline of arithmetic operations. Addition, subtraction, multiplication, and division are the basic operations that make up this system.

It is given that, Kit spent $9.00 on a soft drink and a sandwich, with the food being 3.5 times as expensive as the soft drink.

Suppose the cost of the soft drink is x as a result the price of the sandwich will be 3.5x.

Total cost = $9

x+3.5x=9

4.5x=9

x=9/4.5  

x=  $2.00

The price of the sandwich obtained as,

=3.5x

=3.5× $2.00

=$7

Thus, if Kit bought a soft drink and a sandwich for $9.00 and the sandwich cost 3.5 times much as the soft drink the price of the sandwich and soft drinks will be $7.00 and $2.00 respectively.
