The diagonal of a cube connects two opposite corners.

You can use the diagonal of a cube in a right triangle in which it is the hypotenuse. The legs of the triangle are a diagonal of a face and an edge.

Let the length of the edge be s.

a^2 + b^2 = c^2

[tex] s^2 + 10^2 = (\sqrt{150})^2 [/tex]

[tex] s^2 + 100 = 150 [/tex]

A counterclockwise rotation of 270º about the origin is equivalent to a clockwise rotation of 90º about the origin. Given a point (4, 5), the x-value, i.e. 4 and the y-value, i.e. 5 are positive, hence the point is in the 1st quadrant of the xy-plane.

Solve for h. -18+7h>12+9h

Answers

Answer:

[tex]h<-15[/tex]

Step-by-step explanation:

[tex]-18+7h>12+9h[/tex]

Add 18 to both sides:

[tex]-18+7h+18>12+9h+18[/tex]

[tex]7h>9h+30[/tex]

Subtract 9h from both sides:

[tex]7h>9h+30[/tex]

[tex]-2h>30[/tex]

Multiply both sides by -1 and flip the symbol:

[tex]\left(-2h\right)\left(-1\right)<30\left(-1\right)[/tex]

[tex]2h<-30[/tex]

Divide both sides by 2:

Step-by-step explanation:

Ax − B = C

Dy + E = F

Solve for x and y:

x = (B + C) / A

y = (F − E) / D

So the sum of x and y is:

x + y = (B + C) / A + (F − E) / D

For x + y to be as large as possible, A, E and D must be small, and B, C, and F must be large.  With some trial and error:

x + y = (9 + 8) / 1 + (7 − 3) / 2

x + y = 17 + 2

x + y = 19

For x + y to be as small as possible, we want the first term to be a small fraction, and the second term to be as negative as possible.  So A must be large, B + C must be small, F must be less than E, and D must be small.

x + y = (3 + 4) / 8 + (2 − 9) / 1

x + y = ⅞ − 7

x + y = -6⅛

Which number line shows the points −12/5 and –2.8?

Answers

The answer will be a

The number line that shows the points −12/5 and –2.8 is Option A.

What is a number line?

Integers are arranged at equal intervals along horizontal straight lines called number lines. A number line can be used to represent every number in a series. The endpoints of this line go on forever. Some will have a defined beginning and end. It refers to those as closed number lines. Number lines might be alternatively left empty or blank. A number ladder is a vertical number line.

The given numbers are: −12/5 and –2.8

As we can re-write -12/5 in decimal form= -2.4

Now, we need to mark the number on the number line.

As the number -2.4 lies between -2 and -3 on the left side of zero.

and, -2.4 lies between -the numbers 2.5 and -3.0 on the left side of zero.

Step-by-step explanation:

Hey there!!

It 's so simple.

You remember common property of triangle. (i.e sum of interior angle of a triangle is 180°)

So,

77° + 31° + x = 180°

x + 108° = 180°

x = 180° - 108°

Therefore the measure of angle x is 72°.

Explain how solving -7y > 161 is different from solving 7y > -161

Answer:

Sample response:

Both inequalities use the division property to isolate the variable, y. When you divide by a negative number, like –7, you must reverse the direction of the inequality sign. When you divide by a positive number, like 7, the inequality sign stays the same. The solution to the first inequality is y > -23, and the solution to the second inequality is y <>

Answers

Answer:

The answer is

( 3 , 2)

Step-by-step explanation:

The midpoint M of two endpoints of a line segment can be found by using the formula

[tex]M = ( \frac{x1 + x2}{2} , \: \frac{y1 + y2}{2} )[/tex]

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(12,-7) and (-6,15)

The midpoint is

[tex]M = ( \frac{12 - 6}{2} , \: \frac{ - 7 + 15}{2} ) \\ = ( \frac{6}{2} \: , \: \frac{8}{2} )[/tex]

We have the final answer as
