Answer:

C. 7 pi/ 6

Step-by-step explanation:

The B  points are  ( 8, -2 ) of Endpoint B when M is the midpoint of line AB.

What is midpoint of a segment?

M is the midpoint of line AB.

Endpoint A is (4, 2).

Midpoint M is (6, 0)

Let mid points are ( x,y) and A points are  ( x₂ , y₂ ) and B points are ( x₁ , y₁)

         x = x₁ + x₂/2     ,    y = y₁ + y₂/2

         6 = x₁ + 4/2  ,         0 = y₁ + 2/2

          12 =  x₁ + 4        ,     0 = y₁ + 2

          x₁ = 12 - 4           ,   y₁  = -2

          x₁  = 8                 ,    y₁  = -2

So, the B  points are  ( 8, -2 )

Answer:

Step-by-step explanation:

Ronald's walking speed is 3 miles per hour, and he walks for 2 hours, so he covers 3 * 2 = 6 miles. In the next hour, he runs at a speed of 6 miles per hour, covering an additional 6 miles. Therefore, Ronald traveled a total of 6 + 6 = 12 miles.

Answer:

The sum will be close to 1/4

Step-by-step explanation:

1/8+1/6 is 7/24, and 1/4th of that is 6/24, so it is very close.

Answer: The sum will be close to 1/4

Step-by-step explanation:

You can start by making the fractions have the same denominator, (8*6) which gets you 48

You then want to use the butterfly method, so 1/8 becomes 6/48 and 1/6 becomes 8/48. You then add these up to 14/48.

12/48 is 1/4, and 14/48 is close to 12/48, thus making the answer the first option.

Answer:

In line 4, he did the mistake. He should have square rooted the other side as changing sides changes square to square root.

explanation:

line 1:   \(\sf p^2 - 10p - 11 = 0\)

\(\sf p^2 - 10p = 11\)

line 2:   \(\sf p^2 - 10p + 25 = 11 + 25\)

\(\sf p^2 - 5p -5p+ 25 = 36\)

\(\sf p(p-5)-5(p-5) = 36\)

line 3:   \(\sf (p-5)^2 = 36\)

line 4:   \(\sf p - 5 = \pm \sqrt{36}\)

\(\sf p-5 = 6\)   or   \(\sf p-5 = -6\)

line 5: \(\sf p = 11\)  or   \(\sf p = -1\)

line 6: The solution is p = 11 or p = -1

Answer:

The total cost of adding wallpaper to the room is $487.20

Step-by-step explanation:

Basically, how I got the answer is:

1. The shorter sides of the rectangle are 12 and the longer sides are 14.

2. The formula for a rectangle is A = l x w. The "l" means length and the "w" means width. 14 is the length and 12 is the width. So you should now have A = 14 x 12. If you multiply 14 by 12, you will get 168.

3. Since 1 square foot of carpet costs $2.90, then you should multiply by 168, which will give you $487.20 and that's pretty much it.

Hope this helps! :)

The total cost of adding wallpaper to the room by Mr. Hawkins is $487.20.

Area of a two dimensional shape is the total region which is bounded by the object's shape.

Given that the shape of the wall that Mr. Hawkins covering with wallpaper is rectangular.

The formula to find the area of a rectangular shape is,

Area of a rectangular shape = Length × Width

Given that,

Length of the wall = 14 feet

Width of the wall = 12 feet

Substituting the given measurements to the formula, we get,

Area of the wall = 14 × 12 = 168 feet²

Also, given that,

Cost for each square foot of wall = $2.90

Cost for 168 square feet = $2.90 × 168

                                        = $487.20

Hence the total cost for adding wallpaper to the room is $487.20.

Answer:

an item with an original price tag of $102 that is marked down by 30% will have a sales price of $71.40 -- a savings of $30.60.

Based on the calculations, the equation of this hyperbola in standard form is: A. \(\frac{x\;-\;7}{16} + \frac{y}{9} = 1\).

Mathematically, the equation of a hyperbola in standard form is given by:

\(\frac{x\;-\;h}{a^2} + \frac{x\;-\;k}{b^2} = 1\)

Given the following data:

Center (h, k) = (7, 0)

Vertex (h+a, k) = (7, 4)

Focus = (h+c, k) = (7, 5)

Also, we can deduce that the value of a and c are 4 and 5 respectively.

For the value of b, we would apply Pythagorean's theorem:

c² = a² + b²

b² = c² - a²

b² = 5² - 4²

b² = 9.

Substituting the parameters into the standard equation, we have:

\(\frac{x\;-\;7}{4^2} + \frac{y\;-\;0}{3^2} = 1\\\\\frac{x\;-\;7}{16} + \frac{y}{9} = 1\)

Answer:

How many grams are in 2.2

kilograms?

The solution is

Step-by-step explanation:

There are 2,200 grams in 2.2 kilograms.

There are 1,000 grams in one kilogram.

So, to convert kilograms to grams, you multiply the number of kilograms by 1,000.

To find out how numerous grams are in2.2 kilograms, you would multiply 2.2 by 1,000

So, 2.2 kilograms x 1,000 grams/ kilogram

= 2,200 grams

So, there are 2,200 grams in 2.2 kilograms.

Answer:

To solve for x, we need to isolate x on one side of the equation.

Starting with the equation:

ax - b = 4

We can add b to both sides:

ax = b + 4

Next, we can divide both sides by A:

x = (b + 4) / a

Therefore, the solution for x is:

x = (b + 4) / a

Note that this solution is always defined since a cannot be equal to 0 (as stated in the problem statement).

The  equation accurately represents this statement is "Negative 3 less than 4.9 times a number, x, is the same as 12.8"

The statement is "Negative 3 less than 4.9 times a number, x, is the same as 12.8." We can break it down into two parts:

"4.9 times a number, x": This means we need to multiply a number, x, by 4.9. So the first part of the equation is 4.9x.

"Negative 3 less than 4.9 times a number, x, is the same as 12.8":

This means we need to subtract 3 from the result of multiplying x by 4.9. So the second part of the equation is -3.

Putting it all together, we get:

4.9x - 3 = 12.8

This equation accurately represents the given statement.

The function passes through points (2, 3) and (4, 4) will be y = (1/2)x + 2 thus option (C) is correct.

A straight line on the coordinate plane is represented by a linear function.

A linear function always has the same and constant slope.

The formula for a linear function is f(x) = ax + b, where a and b are real values.

Given points (2, 3) and (4, 4)  

The slope associated with two points (x₁, y₁) and (x₂, y₂) is given by

Slope = (y₂ - y₁)/(x₂ - x₁)

Slope m = (4 - 3)/(4 - 2) = 1/2

The linear equation is given as y = mx + c

Put (2,3) and m = 1/2

3 = (1/2)2 + c

c = 2

Thus, y = (1/2)x + 2 will be the correct.

Hence "The function passes through points (2, 3) and (4, 4) will be y = (1/2)x + 2".

Answer:

  1.147×10^-2 cm

Step-by-step explanation:

You want the difference between the two values 1.87×10^-2 and 7.23×10^-3 expressed in scientific notation.

Addition and subtraction of numbers in scientific notation requires that the multipliers have the same exponent. That exponent can be chosen so no adjustment of the exponent is required in the answer.

  \(1.87\times10^{-2}-7.23\times10^{-3}= 1.87\times10^{-2}-0.723\times10^{-2}\\\\=(1.87-0.723)\times10^{-2}=\boxed{1.147\times10^{-2}}\)

This measurement is in centimeters.

What are mathematics operations?

• An operation is a function in mathematics that converts zero or more input values (also known as "operands" or "arguments") to a well-defined output value.

• The operation's arity is determined by the number of operands.

• Binary operations (i.e., operations of arity 2), such as addition and multiplication, and unary operations (i.e., operations of arity 1), such as additive inverse and multiplicative inverse, are the most commonly studied operations.

• A zero-arity operation, also known as a nullary operation, is a constant.

• The mixed product is an example of an arity 3 operation, also known as a ternary operation.

it is given that :

the diameter of cell G is = 1.87 x 10⁻² cm

the diameter of cell H is = 7.23 x 10⁻³ cm

Now, to find the difference between the diameter of two cells simply subtract the diameter of cell G and H :

difference in the diameter of of G and H = 1.87 x 10⁻² cm - 7.23 x 10⁻³ cm

difference in the diameter of of G and H=1.87 x 10⁻² cm - 0.723 x 10⁻² cm

                                                                  = 1.147x 10⁻² cm

Therefore, the difference in the diameter of of G and H is 1.147x 10⁻² cm
