Answer:

An angle measures 90º if and only if the angle is right.

Step-by-step explanation:

See the image below :)

Answer:

900[tex]\geq[/tex]50+10x; At least 85 hours

Step-by-step explanation:

Nick must make at least 900 dollars, so the amount he has + earns must be greater than or equal to 900 in order to walk out of the store with it.

50 is the amount that Nick already has, and add that to 10x, which gives $10 for every x hour.

To solve, subtract 50 from each side.

850[tex]\geq[/tex]10x

Divide by 10 to solve for x:

85[tex]\geq[/tex]x

Nick must work at least 85 hours.

Answer:

the angle must be 30 degree. because the value of sin30 is ½ and this means 0.5

Answer:

Step-by-step explanation:

All cross-sectional shapes that are parallel or perpendicular to one of the bases of a Cube.

A cross section in mathematics is the illustration of the intersection of an entity by a plane.

In a cube, all the faces which is parallel or perpendicular to one of the faces are congruent to one another.

So, out of all cross-sectional shapes that are parallel or perpendicular to one of the bases of a Cube, are also congruent to one another.

Hence, the cross-sectional shapes that are parallel or perpendicular to one of the bases of a Cube.

Answer:

length = x+6

width = x-6

Step-by-step explanation:

The area of rectangle is:

[tex] \displaystyle \large{ A= l \times w}[/tex]

where A is area, l is length and w is width.

We know the area of this rectangle or table since we are given A = x^2-36.

First, substitute A = x^2-36 in.

[tex] \displaystyle \large{ {x}^{2} - 36 = lw}[/tex]

Then we factor x^2-36, use the difference of two squares:

[tex] \displaystyle \large{ (x + 6)(x - 6) = lw}[/tex]

Compare the terms.

First, we have to understand that length is always longer or greater or have more values than width.

Hence length cannot be x-6 and width cannot be x+6 either.

Thus:

[tex] \displaystyle \large{length = x + 6} \\ \displaystyle \large{width = x - 6}[/tex]

the answer is table d !! good luck :)

Answer:

f(0) = 4

Step-by-step explanation:

F(x) = 4-8x

We know that f(0) = 4-8x

Thus we sub 0 for the x value, resulting in;

f(0) = 4-8(0)

f(0) = 4-0

f(0) = 4

Answer:

x = 120

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles, then

x = 70 + 50 = 120

Answer:

X=120

Step-by-step explanation:

exterior angle of triangle is equal to its two opposite interior angles .

hence, X= 70 + 50

= 120

==============================================

Explanation:

I used GeoGebra (free graphing software) to find the line of best fit, aka the regression line. You can do so by hand, but I think it's tedious busywork and prefer to use technology whenever possible. Other graphing and spreadsheet programs are able to compute the regression line as well.

Check out the diagram below.

Answer:

The point (2, -6) is four below the line y= -2

The reflection will be four below the line y=-2.

Since y=-2 is a horizontal line, the reflection will be vertical,

so (2,-6) will reflect down 6 spaces vertically. -6 + (4*2) = (-6 + 8) =  2  therefore when we establish 4 below the line we just apply * 2 as a double as its across the line each side of the line to find that below the line = 4 = 4*2 and add it to -6

(2,-6) reflected over y=-2 reflects to (2, 2 )
