The price of Stock A at 9 A.M. was $15.75. Since then, the price has been increasing at the rate of $0.05 per hour. At noon, the price of Stock B was $16.53. It begins to decrease at a rate of $0.13 per hour. If the stocks continue to increase and decrease at the same rates, in how many hours will the prices of the stocks be the same?
Answers
Answer:
the price of Stock A and Stock B will be the same after 3.5 hours.
Step-by-step explanation:
15.75 + (0.05 × 3) = 15.90
15.90 + 0.05t= 16.53 - 0.13t
0.05t + 0.13t = 16.53 - 15.90
0.18t = 0.63
t = (0.63 ÷ 0.18)
t = 3.5

1.) Seven more than a number is less than 18. Find the number.
2.) Five more than a number is greater than 26. Find the number.
3.) The sum of two consecutive integers is less than 55. Find the pair of integers with the greatest sum.
4.) The length of a rectangle is 4cm longer than the width. The perimeter is no more than 28cm. What are the maximum possible dimensions for the rectangle?
5.) The sum of three consecutive odd integers is no less than 51. What is the middle integer?
Answers
Answer:
1.) Let x be the number. The inequality can be written as:
x + 7 < 18
Subtracting 7 from both sides, we get:
x < 11
Therefore, the number is less than 11.
2.) Let x be the number. The inequality can be written as:
x + 5 > 26
Subtracting 5 from both sides, we get:
x > 21
Therefore, the number is greater than 21.
3.) Let x be the first integer. The second integer is x+1. The inequality can be written as:
x + (x+1) < 55
Simplifying, we get:
2x + 1 < 55
Subtracting 1 from both sides, we get:
2x < 54
Dividing both sides by 2, we get:
x < 27
Therefore, the largest possible first integer is 26, and the second integer is 27. Their sum is 53.
4.) Let w be the width of the rectangle. The length is 4cm longer than the width, so the length is w + 4. The perimeter is given by:
2(length + width) ≤ 28
Substituting the expressions for length and width, we get:
2(w + 4 + w) ≤ 28
Simplifying, we get:
4w + 8 ≤ 28
Subtracting 8 from both sides, we get:
4w ≤ 20
Dividing both sides by 4, we get:
w ≤ 5
Therefore, the maximum possible width is 5cm, and the maximum possible length is 9cm.
5.) Let x be the first odd integer. The second and third odd integers are x+2 and x+4, respectively. The inequality can be written as:
x + (x+2) + (x+4) ≥ 51
Simplifying, we get:
3x + 6 ≥ 51
Subtracting 6 from both sides, we get:
3x ≥ 45
Dividing both sides by 3, we get:
x ≥ 15
Therefore, the smallest possible first odd integer is 15, and the second and third odd integers are 17 and 19, respectively. The middle integer is 17.

The reflection line is a vertical line, meaning that:
The coordinates of x are reflected in the opposite direction.The coordinates of y remain constant.Hence the x-coordinates are given as follows:
x = -5 is 2 units left of x = -3, hence two units right is x = -3 + 2 = -1.x = -2 is one unit right of x = -2, hence one unit left is x = -2 - 1 = -3.x = -3 is exactly at the line.Hence the coordinates of the image are:

Based on the above, there are 26 rabbits after 1 week.
There are 33 rabbits after 8 weeks.

To find the number of rabbits after a certain number of weeks, we can substitute the number of weeks into the equation r = 25 + w and solve for r.
For example, after 1 week, we have:
r = 25 + w = 25 + 1 = 26
So there are 26 rabbits after 1 week.
Similarly, after 8 weeks:
r = 25 + w = 25 + 8 = 33
So there are 33 rabbits after 8 weeks.

Jake has 150 feet of barb wire and needs to put it on 35 3/4 feet of fencing. How much barb wire can he use for each foot?
Answers
Answer:
4.19 ft
Step-by-step explanation:
Step 1: Change 35 3/4 into a decimal
35 3/4 = 35.75
3/4 = 75/100 = 0.75
Step 2: Move the decimal place 2 places to the right for both numbers
Step 3: Divide 150 by 35.75
(See Attachment)
Tip #1: Divide 2 Places After The Decimal Point While Dividing Decimals, Then Stop
Tip #2: Make The Decimal In The Divisor A Whole Number By Moving The Decimal Point, Then Do The Same Thing To The Dividend.
The length of barbed wire can he use for each foot will be 4.196 feet.
What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
PEMDAS rule means for the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.
Jake has 150 feet of barbed wire and needs to put it on 35 3/4 feet of fencing.
Convert the mixed fraction number into decimal numbers.
35 3/4 = 35 + 3/4
35 3/4 = 35 + 0.75
35 3/4 = 35.75
The length of barb wire can he use for each foot will be
⇒ 150 / 35.75
⇒ 4.196
The length of barb wire can he use for each foot will be 4.196 feet.

A rectangular prism with dimensions 5 inches by 13 inches by 10 inches was cut to leave a piece as shown in the image. What is the volume of this piece? What is the volume of the other piece?
HELP
Answers
The volume of the original rectangular prism is given by:
V1 = length x width x height
= 5 inches x 13 inches x 10 inches
= 650 cubic inches
To find the volume of the remaining piece, you need to determine its dimensions. If you have an image or a description of the piece, you can use that information to calculate its volume. Once you have the volume of the remaining piece, you can subtract it from the volume of the original rectangular prism to get the volume of the piece that was cut out.
To find the volume of the other piece, you can subtract the volume of the piece that was cut out from the volume of the original rectangular prism:
V2 = V1 - V_cut_out
where V_cut_out is the volume of the piece that was cut out.

Banana Cupcakes
makes 10 cupcakes
1 cup granulated sugar
cup vegetable oil
1 large egg
4 tablespoons sour cream
2 medium-sized ripe bananas, mashed
1 cups all-purpose flour
1 teaspoon baking soda
teaspoon salt
1 teaspoon vanilla extract
pinch of nutmeg
You will use the recipe above to answer the following questions:
This recipe serves 10, but you need to serve 30. What number will you need to multiply the amount of each ingredient by to adjust the recipe? How did you determine this number?
How much vegetable oil do you need for 30 cupcakes?
How much flour do you need for 30 cupcakes?
What is the difference in the amount of vanilla extract you would need for 30 cupcakes?
What is the difference in the amount of salt you would need for 30 cupcakes?
In the real world, even though you make adjustments to a recipe to accommodate the number of people you need to serve, you sometimes round the amount of an ingredient instead of using an exact amount. Which ingredient would it make more sense to round rather than coming up with the exact amount? Why?
Answers
Answer: Hey give me 1 hour and ill answer it I'm doing odessyware rn so Ill get back to you later appreciate yo patients.
Step-by-step explanation:
Then, if we want to make 30 servings, we need to use that recipe 3 times. (because x*10 = 30, then x = 30/10 = 3)
This would be equivalent to multiply each ingredient by 3.
for 30 cupcakes we need:
3 cups of vegetable oil.
3 cups of all-purpose flour
(because for each one of these ingredients we needed only 1 cup to make 10 cupcakes).
for 10 cupcakes we need 1 teaspoon of vanilla.
for 30 cupcakes we need 3 teaspoons of vanilla, the difference is 3 - 1 = 2.
So the difference is 2 teaspoons.
About which quantities we should round are those where we may have mixed numbers or big numbers.
For example, we have 4 tablespoons of sour cream for 10 servings, then for 30 servings we should have:
3*4 = 12 tablespoons.
We could round this down to 10 tablespoons.
