What does it mean when a letter and number are together like this
Answer:
multiplication
Step-by-step explanation:
7 x e = f
Answer:
If a number and letter are together, it means it is a multiplication problem. It is the same thing as 7 x e.
Step-by-step explanation:
We don't know what e is because there isn't a number given to us to solve the problem, so we say 7 x e = 7e, but the equation tells us that 7e = f, so 7 x e is equal to f which means 7e is equal to f.
Let me just give a number to e. Let's say e is 5
7e = f
We already know 7e is the same thing as 7 x e, so let's rewrite it
7 x e = f
We will change e to 5 and multiply the numbers together
7 x 5 = f
Now multiply 7 x 5
35 = f
If 35 is equal to f, that means the value of f is 35, so f = 35 ( I don't know if this makes sense lol)
But let's now take the original equation and assume f is 42
7e = f
Remember, 7e is 7 x e, so rewrite your equation
7 x e = f
Now we will change the f to 42
7 x e = 42
To get e, we will have to think about what multiplies by 7 to get 42. We will have to change this to division. We will divide 42 by 7
42÷7 = 6
That means e is 6. Now let's write the equation with changing e to 6
7 x 6 = 42
7 times 6 is 42, so we will multiply that
42 = 42
Now we have equal answers. Of course, 42 is equal to 42
Overall I'm trying to say 7e = f
I'll solve this again, so you won't have to go back up.
7e = f
7 x e = f
f = f
I hope this makes sense lol

Find an equation for the perpendicular bisector of the line segment whose endpoints
are (-8,4) and (-4, -8).
Answer:
y = 1/3x
Step-by-step explanation:
is 8/5 proportional to 24/15 ?
Hey there!
The answer to your question is, yes, it is
Given:
[tex]\frac{8}{5}[/tex] [tex]and[/tex] [tex]\frac{24}{15}[/tex]
To see if they are equal, we can use cross products (see below for information about this, if you don't know what it is). Let us assume they are equal. This would mean that:
[tex]8*15=24*5[/tex]
Let's solve it and see if it is true:
[tex]8*15=24*5[/tex]
[tex]120=120[/tex]
Therefore, they are proportional.

Angle is in standard position and (-5, -7) is a point on the terminal side of 0.
What is the exact value of sec 0 in simplest form with a rational denominator?
Answer:
Step-by-step explanation:
Don't use 0 as a substitute for θ. 0 is always 0.
cosθ = -5/(2√15)
secθ = 1/cosθ = -2√15/5
The exact value of sec θ is -8.6/5.
What is Trigonometry?One area of mathematics known as trigonometry examines the relationship between the sides and angles of a right triangle. The relationship between sides and angles is defined for 6 trigonometric functions.
We have,
Point(-5, -7).
Here, x= -5 and y= -7
So, r = √x² + y²
r= √(-5)² + (-7)²
r= √25 + 49
r = √74
r= 8.6
So, sec θ= H/ B
= r/x
= 8.6/ (-5)
= -8.6/ 5

Find the value of X and Y
Answer:
x = 30
y = 5
Step-by-step explanation:
Because the top triangle shows 3 congruent angles, we know it's an equilateral.
Therefore 8y = 40
y = 5
______________
Now we have two sides of the triangle: 40 and 80.
The lower left angle of the whole triangle must be 90 degrees because if the hypotenuse is twice the adjacent side, it must be a 30-60-90 triangle.
So, the larger angle containing angle x must be 90 degrees. And because we know that the adjacent angle (equilateral triangle) is 60 degrees, angle x must be 30.
Match, each of the given measures to the correct side or angle 11, 7.5, 13

Which equation can we use to find the equal volume of concrete in cubic feet darlin' needs for the staircase
Answer:
The equation required to find the volume of concrete is:
L X W X H.
Step-by-step explanation:
L = Lenght
W = Width
H = Height
To calculate the required volume for concrete, you'd need to multiply the measures of all the dimensions together such as the lenght and the breath (which gives you the Area) and the thickness or height of the staircase.
If the calculation is being expressed in Feet, the answer will also be expressed as Volume of concrete in Cubic feet.

Answer:
$80
Step-by-step explanation:
Substitute x for 40 in both equations. Let's start with 50 + 12x. The equation becomes 50 + 12(40). First, multiply 12 by 40 to get 480. Now add 480 to 50 to get a total of $530 in printing fees for Company A.
Now, let's move on to 10 + 15x. That becomes 10 + 15(40). First, multiply 15 by 40 to get 600. Then add 10 to 600 to get $610 in printing fees for Company B.
Now that we know the total costs, let's subtract them to get our difference. Simply subtract 530 from 610 to get our final answer: an $80 difference in printing fee costs between the companies.

㏒(2x²) = ㏒(2) + 2㏒(x)
Step-by-step explanation:
As given, ㏒(2x²)
As we know that ㏒(MN) = ㏒(M) + ㏒(N)
⇒㏒(2x²) = ㏒(2) + ㏒(x²)
As we know that ㏒(xⁿ) = n㏒(x)
⇒㏒(2x²) = ㏒(2) + 2㏒(x)
∴ we get
㏒(2x²) = ㏒(2) + 2㏒(x)

Raphael deposited $6,500 in an account that pays 4.25% interest, compounded annually. He left the money in the account for 4 years, without depositing money to it or withdrawing money from it.
At the end of the 4 years, how much interest in dollars and cents did the account earn?
Answer:
$1105
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 4.25%/100 = 0.0425 per year,
then, solving our equation
I = 6500 × 0.0425 × 4 = 1105
I = $ 1,105.00
The simple interest accumulated
on a principal of $ 6,500.00
at a rate of 4.25% per year
for 4 years is $ 1,105.00.
Which of the following expressions is equivalent to (-3x5y) (-4x9y2)
Answer:
12x^227xy^2 - 20xy4y^3
Step-by-step explanation:
(-3x5y) (-4x9y^2)
first : -3x (-4x9y^2) = 12x^227xy^2
second: 5y(-4x9y^2) = -20xy45y^3
then we add them (12x^227xy^2) + ( -20xy45y^3)
= 12x^227xy^2 - 20xy45y^3

On Monday Sylvia spent 5/12 of a day driving to her cousins house. On Friday she spent the same amount of time driving home. What fraction of a day did Sylvia spend driving to her cousins house and back?
Answer: The fraction of a day did Sylvia spend driving to her cousins house and back = [tex]\dfrac{5}{6}[/tex]
Step-by-step explanation:
Given: Fraction of day Sylvia spent to drive her cousins home = [tex]\dfrac5{12}[/tex]
Fraction of day Sylvia spent to drive her home back= [tex]\dfrac5{12}[/tex]
Total fraction of day Sylvia spend driving to her cousins house and back = [tex]\dfrac5{12}+\dfrac{5}{12}[/tex]
[tex]=\dfrac{5+5}{12}\\\\=\dfrac{10}{12}\\\\=\dfrac{5}{6}[/tex]
Hence, the fraction of a day did Sylvia spend driving to her cousins house and back = [tex]\dfrac{5}{6}[/tex]
