The horizontal distance of E is 9 units to the east of point F. Determine the coordinates of F if the coordinates of E are (3,8).
Answer:
(-6,8)
Step-by-step explanation:
By reading the question you can determine that point E is to the east, or the right, of point F by 9 units. This ultimately means you must subtract 9 units on the horizontal (x-axis) in order to get to point F.

A stocks value decreased by 7 points each day for 2 weeks. Which numeric expression can be used to find out what the stock value was after the 2 weeks?
Answer:
x - 98
Step-by-step explanation:
Given the question :
A stocks value decreased by 7 points each day for 2 weeks. Which numeric expression can be used to find out what the stock value was after the 2 weeks?
Let the initial value of the stock = s
Rate of decrease = 7 points per day
Number of days in a week = 7
Hence, 2 weeks = ( 2 * 7) = 14 days
Total decrease in stock over the 2 weeks period :
(Decrease per day × number of days)
(7 points × 14) = 98 points
Stock value after 2 weeks :
(Initial stock value - decrease in stock over the 2 weeks period)
= x - 98

What is the mass of the Apple juice with a volume of 200.0 mL? The density of apple juice is 0.789 g/mL.
Answer:
mass = 157.8 gStep-by-step explanation:
The mass of a substance when given the density and volume can be found by using the formula
mass = Density × volumeFrom the question
Density = 0.789 g/mL
volume = 200 mL
Substitute the values into the above formula and solve for the mass
That's
mass = 0.789 × 200
We have the final answer as
mass = 157.8 gHope this helps you
The diameter of a circle increased from 25cm to 25.8cm. Find the percentage increase in its circumference.
Answer:
3.1% increase
Step-by-step explanation:
Diameter1=25cm
Radius1=12.5cm
Circumference1=2x22/7x12.5
Diameter2=25.8cm
Radius2=12.9cm
Circumference2=2x22/7x12.9
% increase =Circumference2-Circumference1/Circumference2 x 100%= 2x22/7x12.9-2x22/7x12.5 / 2x22/7x12.9 x100%
12.9-12.5/12.9 x 100%

if ( 3x + 2) (5x + 1) = ax2 + bx + 2
What is the value of a - b ?
a - b= 2
Step-by-step explanation:
expanding the brackets
we have 15x^2+13x+2
a= 15 b= 13
thus, a-b =15-13
=2
The value of a - b if, (3x + 2) (5x + 1) = ax² + bx + 2 is 2 i.e a - b = 2.
What is expression?At least two numbers or variables, one or more arithmetic operations, and a statement are all required components of a mathematical expression. The term "expression" or "mathematical expression" refers to a finite collection of symbols that are well-formed in line with context-dependent criteria.
Given:
(3x + 2) (5x + 1) = ax² + bx + 2
Write the left term of the equation in the format of the right term,
3x (5x + 1) + 2(5x + 1)
15x² + 3x + 10x + 2
15x² + 13x + 2
Compare the above equation to ax² + bx + 2,
a = 15 and b = 13
Calculate the value of a - b as shown below,
a - b = 15 - 13
a - b = 2

a piece of lumber is 2 1/4 ft long is cut into 3 equal pieces .How long will each piece of cut wood be ?
Answer: Each piece would be 3/4 feet long
Step-by-step explanation:
If the piece of lumber is 2 1/4 ft long, and it is cut into 3 pieces then divide
2 1/4 by 3 to find out how long each piece of cut wood would be.
2 1/4 is the same as 9/4
[tex]\frac{9}{4} / \frac{3}{1}[/tex] = 9/12 which also simplifies to 3/4
If M is the midpoint of XY, XM=2x+5 and YM=25, find XY.
Answer:
50
Step-by-step explanation:
Since M is the midpoint of XY, this means that XM and MY must be equivalent from the definition of midpoint.
So:
[tex]XM=MY[/tex]
The entire length of the segment (XY) is:
[tex]XY=XM+MY[/tex]
We know that XM is equivalent to MY. Substitute MY for XM:
[tex]XY=MY+MY[/tex]
Combine like terms;
[tex]XY=2MY[/tex]
We are told that YM (or MY) is 25. So:
[tex]XY=2(25)[/tex]
Multiply:
[tex]XY=50[/tex]
So, the length of XY is 50.
And we're done!

In a certain grocery store, strawberries cost $4.96 per pound ( 4.96 dollars/lb d o l l a r s / l b ). What is the cost per ounce?
Cost of the strawberry will be $0.31 per ounce.
Given in the question,
Strawberry cost → $4.96 per poundWe can write the cost as [tex]\frac{4.96\text{ Dollars}}{1\text{Pound}}[/tex].
Since, 1 pound = 16 ounces
To convert the cost of the strawberry in dollars per ounce, multiply the price by the conversion factor [tex]\frac{1\text{ Pound}}{16\text{ Ounces}}[/tex].
So the cost of strawberry = [tex]\frac{4.96\text{ Dollars}}{1\text{Pound}}\times \frac{1\text{ Pound}}{16\text{ Ounces}}=0.31\text{ Dollars per ounce}[/tex]
Therefore, cost of the strawberry will be $0.31 per ounce.

A rectangle has side lengths of 2 units and 4 units. Can you form a different quadrilateral using the same four side lengths? Explain why or why not Support your explanation with drawings. please explain this for me. im so lost
Answer:
a kite
Step-by-step explanation:
Yes, you can form a kite. The top two would be 2 units, and the bottom two would be 4 units. It would still have two of each, just like the rectangle, but would be a different quadrilateral.
Alternately, you could turn the rectangle into a parallelogram by leaning it. Rectangles have 90 degree angles, so it wouldn't be a rectangle anymore.

The equation that should be solved in order to find x is [tex]sin\ 26^\circ =\frac{x}{10}[/tex]. The correct option is C. [tex]sin\ 26^\circ =\frac{x}{10}[/tex]
Trigonometry: Solving a right triangleFrom the question, we are to determine which equation should one solve to find x
Considering the right triangle in the diagram,
Opposite = x
Adjacent = 9
Hypotenuse = 10
By SOH CAH TOA
We have that
[tex]sin\theta = \frac{opposite}{hypotenuse}[/tex]
Where θ is the angle
Then, we can write that
[tex]sin\ 26^\circ =\frac{x}{10}[/tex]
This is the equation that should be solved in order to find x

What is the solution to the proportion? Round the answer to the nearest tenth if necessary. StartFraction 52 over x EndFraction = StartFraction 9.5 over 3.25 EndFraction x = 14.6 x = 17.8 x = 157.8 x = 169.0
Answer: 17.8
Step-by-step explanation:
The solution to the proportion would be x = 17.8 which is the correct option (B).
What is Ratio?A ratio is defined as a relationship between two quantities, it is expressed as one divided by the other
What are Arithmetic operations?Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operations is called the arithmetic operator.
/ Division operation: Divides left-hand operand by right-hand operand
For example 4/2 = 2
We have been the given proportion as:
⇒ 52 : x = 9.5 : 3.25
⇒ 52/x = 9.5/3.25
⇒ 52/x = 2.923
Cross multiplication, and we get
⇒ x = 52/2.923
Apply the division operation,
⇒ x = 17.8
Therefore, the solution to the proportion would be x = 17.8.

In the 21st century, people measure length in feet and meters. At various points in history, people measured length in hands, cubits, and paces. There are 9 hands in 2 cubits. Write an equation to express the relationship between hands, LaTeX: hh, and cubits, LaTeX: cc. Explain your reasoning under your equation.
Answer: 1 hand = 0.22... cubits.
Step-by-step explanation:
We want to write the relation between hands and cubits.
We know that there are 9 hands in 2 cubits.
So we can write:
9 hands = 2 cubits.
Now, we want to have an unit in the left side (so we can see how many cubits are equal to exactly one hand).
Then we can divide by 9 in both sides of the equality.
(9 hands)/9 = (2 cubits)/9
1 hand = 0.22... cubits.
Answer:
22.5 hands = 3 paces

three times the sum of a number and 15 is 24
Answer:
[tex]\huge\boxed{\sf x = -7}[/tex]
Step-by-step explanation:
Let the number be x
So,
=> The sum of number and 15 is x + 15
=> Three times will be 3(x+15)
Given that it equals 24
So, the given condition is:
3(x+15) = 24
Resolving Parenthesis
3x + 45 = 24
Subtracting 45 to both sides
3x = 24 - 45
3x = -21
Dividing both sides by 3
x = -7
