Answer:

<h2>A plane consists of an infinite set of lines.</h2><h2>A line has one dimension, length. </h2>

Step-by-step explanation:

The choices are

A point in the form (x, y) has two dimensions.
A plane has a definite beginning and end.
A line has one dimension, length.
A point consists of an infinite set of lines.
A plane consists of an infinite set of lines.

In Ecludian geometry, undefined term are the plane, point and line. Becasue these terms are too intuitive, we don't need to demonstrate them, they just exits, they are too primitive to be defined, that's why they are undefined term.

However, there are some characteristics about each term, for example, a line and a plane are infinite, the plane is formed by infinite of lines and the line is formed by infinite set of points. Additionally, a line has one dimension only, because it's formed by infinte set of points, which doesn't have a dimensions as a singular term, but all together form a length.

Therefore, the right answers are C and E.

The solution to 5 - 3x> 35 is either x>-10 or -10> x. which solution is correct

velikii [3]

It should be x < -10 because when you divide by a negative number the inequality sign flips.

If you have 30$ and you need to find 8%, and add to 30$ then find 15% of that, and what’s your total?

stira [4]

Answer:

Our total amount value is $4.86.

Step-by-step explanation:

The total amount given is $30.

Now 8 % of $30 = $\frac{8}{100} \times 30 = 2.4$

or, 8% of $30 = $2.4

Now adding $30 and $2.4,

$ 30 + $2.4 = $32.4

Finding 15% of the total $32.4,

we get $\frac{15}{100} \times 32.4 = 4.86$

or, 15% of $32.4 = $4.86

hence, our total amount value is $4.86.

Y=1/2×-6 ×=-4 what is the solution to the system of equations

hodyreva [135]

Answer:

(-4, -8)

Step-by-step explanation:

Use the substitution method. x = -4, so y = (1/2)x - 6 becomes:

y = (1/2)(-4) - 6, or y = -2 - 6, or y = -8.

The solution is (-4, -8).

At a point on the ground 46 feet from the foot of a tree, the angle of elevation of the top of the tree is 68 degrees. What is t

Mandarinka [93]

Answer:

114 ft

Step-by-step explanation:

Imagine or construct a right triangle with the 46 ft leg lying on the ground. This is the "adjacent side" of the triangle; it lies immediately adjacent to the 68 degree angle. The side opposite this angle is h, the height of the tree.

The tangent function includes angle, opp side and adj side:

tan 68 degrees = opp / adj = h / (46 ft), and so:

(46 ft)*tan (68 degrees) = opp = h

Then the height of the tree is h = (46 ft)(2.47) = 114 ft
