Answer:

  30√2 feet ≈ 42.4 feet

Step-by-step explanation:

If the right angle is at Jerry, then Jerry is at a base location between Tom and Mark. That is, Tom and Mark are at opposite corners of the diamond. The distance from Tom to Jerry is the length of one side of the square. Its diagonal is √2 times the side length, so ...

  the distance from Tom to Mark is 30√2 feet ≈ 42.4 feet

The answeris (71/5)..

Answer:

C

Step-by-step explanation:

Solve by completing the square (Show all work)
x2 – 10x + 10 = 35

Please help!

Answers

Answer:

x=5+5√2; x=5-5√2

Step-by-step explanation:

To complete the square we need to turn part of the equation into a perfect square trinomial. Remember, in any equation we can do anything we like to the numbers as long as both sides stay equal.

First, let's subtract 10 from both sides.

x^2-10x=25

This does not factor, so we need to turn it into a perfect square trinomial by adding the quantity equal to (b/2)^2. In this case, (b/2)^2 is 25.

x^2−10x+25=25+25

IMPORTANT: You must keep the sides of the equation equal, so we added a 25 to the right side as well to keep the equation true.

From here we can factor, simplify and find our zeroes.

(x-5)(x-5)=50

(x-5)^2=50

x-5=±√50

x=5±√50

√50=5√2

So our final answer is:

x=5+5√2; x=5-5√2

Write the standard form of the equation of a line with a slope of 3 passing through the point (-1, -5).

Select one:
a. -x + 3y + 14 = 0
b. x - 3y - 14 = 0
c. 3x - y - 2 = 0
d. -3x + y + 2 = 0

Answers

Answer:

Step 1: We start by writing the equation of the line in slope-intercept form by solving for b.

[tex]-5 = 3(-1) + b\\\\-5 = -3 + b\\\\-2 = b\\[/tex]

Step 2: Now we set up the equation of the line in slope-intercept form.

[tex]y = 3x - 2[/tex]

Step 3: We can now convert the above equation from slope-intercept form to standard form.

[tex]y = 3x - 2\\\\-3x + y = -2\\\\-3x + y + 2 = 0[/tex]

The equation of the line in standard form is: D: -3x + y + 2 = 0.

a lawnmower that regularly sells for %150 was discounted by 25% off.

Questions:

Markup?

Sale price?

Answers

To take 25% off, you want to do 1-.25 which equals .75. That means that you have to pay 75% of the cost after the 25% off discount.

Multiply the cost, 150, by .75 to find the new price after the discount.
150x.75=112.5

The price is now $112.50

LSA of a cube is 1600cm2, then its edge is:

Answers

Answer:

20 cm

Step-by-step explanation:

A cube has 6 faces. Two of the faces are bases. The other four faces are lateral faces.

Let the area of 1 face = x

4x = 1600 cm^2

x = 400 cm^2

Since the area of 1 face is 400 cm^2, then the side length is sqrt(400 cm^2) = 20 cm

Answer: 20 cm

Type the correct answer in the box. Use numerals instead of words. What value of x makes this equation true? -2x + 3 = -15
What does x =

Answers

Answer:x=9

Step-by-step explanation:

-2x+3=-15

Subtract 3 on both sides:

-2x+3-3=-15-3

-2x=-18

Divide -2 on both sides:

-2x/-2=-18/-2

x=9

If the expression (- 2x + 3) is equivalent to (- 15), then [x] is equivalent to 9.

What is a mathematical equation and expression?In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.A mathematical equation is used to equate two expressions.

Given is the equation as follows -

- 2x + 3 = - 15

The given equation is -

- 2x + 3 = - 15

Solving, we get -

- 2x = - 15 - 3

- 2x = - 18

 2x = 18

 x = 9

Therefore, if the expression (- 2x + 3) is equivalent to (- 15), then [x] is equivalent to 9.
