why isit posible to calculate the volume of a skewed prism or oblique cylinder with the same formula as the euation for the volume of a right prism or cylinder?

Answer:

7(x4) = 8-x

Step-by-step explanation:

Answer:

x= -2

Step-by-step explanation:

7(4+x)=8-3x would be your equation

your first step would be to move your 3x to the other side of the equation by adding 3x to both sides after this your equation should look as follows: 7(4+x)+3x=8 2nd: you should distribute your 7 to the numbers inside of the parenthsis and combine like terms to get 10x+28=8 then you move your 28 to the other side by subracting 28 and you will get 10x=-20 divide by ten to get the answer which is x=-2

It is the first one because the X side is going up at a steady rate and the Y is also going up at a steady rate

From the given table, table 1 represents the linear function.

Rate of change can be used to detect a linear function.

We can calculate rate of change to check whether the given coordinates represent linear relationship or not.

Formula used to calculate rate of change, m

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex].......................................................1

For table 1:

Calculating value of m using eq 1 for points (2,7) and (4,9)

For table 2:

Calculating value of m using eq 1 for points (1,7) and (2,9)

[tex]m=\dfrac{9-7}{2-1}\\\\m=2[/tex]

Similarly,

Calculating value of m using eq 1 for points (3,12) and (4,15)

m=3

Value of slope changes from 2 to 3. Thus, it does not show linear relationship.

For table 3:

Calculating value of m using eq 1 for points (1,7) and (2,11)

[tex]m=\dfrac{11-7}{2-1}\\\\m=4[/tex]

Calculating value of m using eq 1 for points (3,12) and (4,13)

m=1

Value of slope changes from 4 to 1. Thus, it does not show linear relationship.

For table 4:

Calculating value of m using eq 1 for points (2,7) and (4,9)

[tex]m=\dfrac{9-7}{4-2}\\\\m=1[/tex]

Calculating value of m using eq 1 for points (6,12) and (8,15)

m=3/2

Value of slope changes from 1 to 3/2. Thus, it does not show linear relationship.

So, the Slope of table 1 is the same for all the coordinates. Thus, table 1 represents a linear function.

To find the equation, break apart the question.

twice the difference of a number and 7 equals 2. - "Twice" means we are multiplying by 2, or x 2

twice the difference of a number and 7 equals 2. "The difference of a number and 7" means we are subtracting n - 7, and this is being multiplied by 2 so we have n - 7 x 2 so far.

twice the difference of a number and 7 equals 2. "Equals two" means the equation is equal to 2, or = 2, so our equation is n - 7 x 2 = 2.

The value of the number based on the information given is 8.

Let the number be represented by x.

Since we are given the equation that twice the difference of a number and 7 equals 2, the equation to solve this will be:

2(x - 7) = 2

2x - 14 = 2

2x = 2 + 14

Given a straight line segment AB with points A, O, and B, and angle measures <COA, <COD, and <DOB, we find <COD to be 45 degrees using angle sum properties.

In the given scenario, we have a straight line segment AB, and points O, A, and B lying on it. We are required to find the measure of angle COD, denoted as <COD. According to the information provided, <COA is (3x + 94), <COD is (x + 36), and <DOB is (2x - 4).

Since A, O, and B are collinear, the sum of the angles around point O must be 180 degrees. Therefore, <COA + <COD + <DOB = 180 degrees. Substituting the given angle measures into the equation, we get:

(3x + 94) + (x + 36) + (2x - 4) = 180.

Combining like terms and solving for x:

6x + 126 = 180,

6x = 54,

x = 9.

Now that we have the value for x, we can find <COD by substituting it into the expression (x + 36):

<COD = 9 + 36 = 45 degrees.

Therefore, the measure of angle COD is 45 degrees.

7 and trinomial i believe !

Answer:

n = -8

Step-by-step explanation:

The variable has 4 subtracted and that quantity is multiplied by 5. You can find the value of the variable by reversing these operations, in reverse order. That means you first divide both sides of the equation by 5:

5(n-4)/5 = -60/5

n -4 = -12 . . . . . . simplify

Then you undo the subtraction of 4. You accomplish that by adding 4 to both sides of the equation.

n -4 +4 = -12 +4

n = -8 . . . . . . . . . simplify

_____

This equation can also be solved by first eliminating parentheses. Then you have

5n -20 = -60

Now, the variable is multiplied by 5, then 20 is subtracted from the sum. Reversing these operations in reverse order, we first add 20 to both sides of the equation:

5n -20 +20 = -60 +20

5n = -40 . . . . . . . . . . . . . simplify

Then we undo the multiplication by dividing both sides of the equation by 5:

n = -8

_____

The rule to remember is "whatever you do to one side of the equation must also be done to the other side". This is what keeps the equal sign valid.

Answer:

n = - 8

Step-by-step explanation:

There are 2 possible approaches to solving this question

method 1

5(n - 4) = - 60 ( divide both sides by 5 )

n - 4 = - 12 ( add 4 to both sides )

n = - 8

method 2

5(n - 4) = - 60 ( distribute left side )

5n - 20 = - 60 ( add 20 to both sides )

5n = - 40 ( divide both sides by 5 )

n = - 8

Step-by-step explanation:

If 12 students is 3/8 of the class, the ones who earned A's, then 5/8 did not earn A's.

Let c represent the total number of students in the class.

Then (3/8)c = 12, and c = (8/3)(12) = 32.

5/8 of these 32 students did not earn A's:  (5/8)(32) = 20.

Answer:

area = (exact) 88pi ft^2 or (approximate) 276 ft^2

Step-by-step explanation:

The surface area of a cylinder is the sum of the areas of the bases, two circles, and the lateral area which is a rectangle.

Each base is a circle, and the two bases are congruent, so find the area of one base and multiply by 2.

The lateral area is a rectangle. You need to find the length and width of the rectangle. Think of a can of food with a label wrapped around. If you make a vertical cut from one base to the other, and you unwrap the label, you will see that the lateral surface of a cylinder is a rectangle that has the height of the cylinder as its length, and the circumference of the base are its width.

area of circle = pi *r^2

area of rectangle = length * width

length of rectangle: length = 2(pi)r

width of rectangle: width = height = h

total area of cylinder = area of bases + lateral area

total area of cylinder = 2 * pi *r^2 + 2(pi)r * h

total area of cylinder = 2 * pi * (2 ft)^2 + 2 * pi * 2 ft * 20 ft

total area of cylinder = 8pi ft^2 + 80pi ft^2

total area of cylinder = 88pi ft^2

The exact area is 88pi ft^2.

If you need an approximate area, then use 3.14 for pi.

area = 88 * 3.14 ft^2

area = 276 ft^2

Step-by-step explanation:

The value of the expression (8^7)/(8^7) is 1.

The expression (8^7)/(8^7) can be simplified using the properties of exponents. According to the quotient rule of exponents, when dividing two numbers with the same base, the exponents are subtracted. In this case:

   (8^7)/(8^7) = 8^(7-7) = 8^0

Any non-zero number raised to the power of 0 is equal to 1, according to the fundamental property of exponentiation. Therefore, the value of the expression (8^7)/(8^7) is 1.

Hence, the value of the expression (8^7)/(8^7) is 1.

By applying the quotient rule of exponents, we simplify the expression to 1, reflecting the property of exponentiation where any non-zero number raised to the power of 0 equals 1.
