f divided by -7 = -8
Answer:f=56 I hope this helps
Step-by-step explanation:
f divide (-7) =-8
Dividing a positive and a negative equals a negative: (+) divided sign (-) =( -) and then
Write the division as a fraction
-1/7f=-8
Multiply both sides of the equation by -7
f=56
Answer:
f = 56
Step-by-step explanation:
Given statement,
→ f divided by -7 is -8.
Forming the equation,
→ f/-7 = -8
Now the value of f will be,
→ f/-7 = -8
→ f = -8 × -7
→ f = 8 × 7
→ [ f = 56 ]
Hence, the value of f is 56.

Juice wa packed in individual juice boxe of 1/2-cup each. A carton of 64 juice boxe wa hrink-wrapped and hipped to a tore. How many gallon of juice were in the hrink-wrapped carton?
The shrink-wrapped carton of 64 juice boxes contained 2 gallons of juice.
To find out how many gallons of juice were in the shrink-wrapped carton, we first need to convert the number of juice boxes to cups and then convert that amount to gallons.
Each juice box contains 1/2 cup of juice, so 64 boxes contain 64 * (1/2) = 32 cups.
There are 16 cups in 1 gallon, so to convert 32 cups to gallons, we divide 32 cups by 16 cups/gallon.
32 cups / 16 cups/gallon = 2 gallons
So, the shrink-wrapped carton of 64 juice boxes contained 2 gallons of juice.

Calculate the length of the unknown side of this right angled triangle
Base: 8cm
Length: 9cm
The length of the unknown side of this right angled triangle is 12cm.
This is a question about the Pythagorean theorem, which states that in a right-angled triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. The theorem can be written as c^2 = a^2 + b^2, where c is the hypotenuse, and a and b are the other two sides.
In this case, we know that the base of the triangle is 8cm and the length is 9cm.
So we can use the formula c = √(a^2 + b^2)
c = √(8^2 + 9^2)
c = √(64 + 81)
c = √(145)
c = 12cm
Therefore, the length of the unknown side of this right angled triangle is 12cm.

Total charge that Tom has to pay is $142.2, and the express function for the monthly charge is c(x) = 105 + (x -4) * 12
How to determine the monthly charge function and total charge for Tom on that month?
As per data given, monthly value given is $105 = free text + free call + 4gb and extra gigabyte x $12. Tom that use 7.1 of data will be charge as follow:
Tom charge = normal use + extra use
To charge = 105 + extra gigabyte x12
Extra gigabyte = tom use - normal use
Extra gigabyte = 7.1 - 4
Extra gigabyte = 3.1
Tom charge = 105 + 3.1 x 12
Tom charge = 105 + 37.2
Tom charge = 142.2
The expression of monthly charge, since we have already define that value is $105 = free text + free call + 4gb and extra gigabyte x $12. We can see that text is not charge and call is not charge. So the formula will be:
Monthly charge = 105 + (extra gigabyte - 4) x 12

Which of the following are solutions to x < 12?
l. x = -4
II. x = 0
III. x = 12
IV. x = 13
Answer:
I. x = -4 and II. x = 12
Step-by-step explanation:
For this problem, you would simply need to plug in the values and see if the inequality is true, and if it is, it is a solution, so let's go through the options.
Plugging in x = -4 gives us: -4 < 12 which is true since negative four is less than positive twelve, so this is a solution.
Plugging in x = 0 gives us: 0 < 12 which is true since zero is less than twelve, so this is a solution.
Plugging in x = 12 gives us: 12 < 12 which is false since twelve is not less than twelve but is rather equal to it. if the less than symbol had a line under it, it would also include values equal to it in which case x = 12 would be a solution but since it doesn't, this is not a solution.
Plugging in x = 13 gives us: 13 < 12 which is false since thirteen is not less than twelve but is rather greater than it, so this is not a solution.

What is trigonometry?
Trigonometry is based on the study of the six basic trigonometric functions: sine (sin), cosine (cos), tangent (tan), cosecant (csc), secant (sec), and cotangent (cot). These functions are defined in terms of the ratios of the sides of a right triangle. For example, the sine of an angle in a right triangle is the ratio of the length of the side opposite the angle to the length of the hypotenuse.
In the given figure, we can apply the trigonometric ratio, we get
sin22 = x/4000
0.374 = x/ 4000
x = 0.374 * 4000

What is Pythagoras theorem?
The hypotenuse's square length is equal to the sum of the squares of the lengths of the other two sides of the right-angled triangle, according to the Pythagorean theorem, commonly known as the Pythagoras theorem.
Here, The 75 inches represents the length of diagonal of the TV because the length of TV is always measured diagonally. So, the diagonal's length is 75 inches.
We've width as 43.25 inches.
Since TV is of the shape of rectangle, we can calculate the height by applying Pythagoras theorem.
So, we've hypotenuse² = (side 1)² + (side 2)²
It can be written as,
diagonal² = height² + width²
(75)² = height² + (43.25)²
height² = (75)² - (43.25)²
= 5625 - 1870.5625
= 3754.4375

Where is the zero of a function?.
Any alternative for the variable in a function that results in a zero answer is said to as the zero of a function.
The x-intercept(s) of the function's graph, or the real zero of a function, is where the function's graph hits the x-axis graphically.
The values of the variable in a function that allow the function to equal zero are termed the zeros of the function. The places on the x-axis where the graph crosses the x-axis are referred to as a function's zeros graphically. In other respects, we can say that the zeros of something like a function are the x-intercepts of the graph.
Finding the values of the variable that correspond to the function's zeros can be achieved by equating the function to 0. By calculating the polynomial and then equating it to 0, we can discover the zeros for polynomials.

prove that:sinA/1-cosA-1=1/cosA
Answer:
Step-by-step explanation:
To prove that sinA/(1-cosA) = 1/cosA, we will start with the left-hand side and simplify it using trigonometric identities.
sinA/(1-cosA) = sinA/(1-cosA) * (sin^2A + cos^2A) / (sin^2A + cos^2A)
= (sinAsin^2A + sinAcos^2A) / (sin^2A + cos^2A - sin^2AcosA - cos^2AcosA)
= (sinAsinAcosA + sinAcosAcosA) / (sinAcosA - cosAcosA)
= sinA/cosA / (sinA/cosA - 1)
= 1/cosA
Therefore, sinA/(1-cosA) = 1/cosA, which is true.
How many solutions does Y =- 2x 3 have?.
The equation, Y = - 2x + 3 has infinitely many solutions.
Here we are given the equation y = 2x + 3. Now since this equation has 2 variables, it can be easily plotted on a graph. After plotting this equation, we can see that it makes a never-ending line, hence, this equation will have infinitely many solutions.
For any equation to have a solution, there must be an intersecting point or a common value for x or y.
Here for every value of x, we get a different value of y, which can be easily seen in the graph.
Furthermore, when an equation has 2 variables, there must be at least 2 equations for the system to have a unique solution, hence the given equation has infinitely many solutions.
