Vertical line test. Also there is only one y for every x.
BaLLatris [955]3 years ago

One way to tell if a relation is a function is by using something called the vertical line test. In other words, if we can draw a vertical that passes through more than one point on a graph, then the relation does not represent a function. Another way to tell if a relation represents a function is by looking at the X coordinates of each ordered pair. If any of the ordered pairs have the same X coordinate, then the relation is not a function.

A line, ray, segment, or plane that intersects a segment at its midpoint is called?
Hunter-Best [27]

A segment, ray, line, or plane that is perpendicular to a segment at its midpoint is called a perpendicular bisector. Converse of the Perpendicular. Bisector Theorem. If a point is on the perpendicular bisector of a segment, then it is equidistant from the endpoints of the segment.

From the given angle measurements, you can’t directly find the measure of angle L. However, you can find the measurement of angl
DaniilM [7]

The measurement of angle L = 50°.

Solution:

The given image is a rectangle.

The measurement of ∠A = 25°

The measurement of ∠B = 25°

ABC is a triangle.

Sum of the interior angles of the triangle = 180°

⇒ m∠A + m∠B + m∠C = 180°

⇒ 25° + 25° + m∠C = 180°

⇒ 50° + m∠C = 180°

⇒ m∠C = 180° – 50°

⇒ m∠C = 130°

Sum of the adjacent angles in a straight line = 180°

⇒ m∠C + m∠L = 180°

⇒ 130°  + m∠L = 180°

⇒ m∠L = 180° – 130°

⇒ m∠L = 50°

Hence the measurement of angle L = 50°.

60 children go to a nursery. The ratio of girls to boys is 3 : 2
dezoksy [38]

Answer:

Girls (Morning)  = 16

Step-by-step explanation:

<em>60 children go to a nursery. The ratio of girls to boys is 3 : 2</em>

Number of Boys = 3 / (3 + 2) * 60 = 3/5 * 60 =36

Number of Girls = 2 / (3 + 2) * 60 = 2/5 * 60 = 24

<em>Three quarters of the children go to the nursery in the morning.</em>

Number of children (Boys + Girls) = 3/4 * 60 = 45

<em>The rest of the children go to the nursery in the afternoon.</em>

Number of children (Boys + Girls) = 60 - 45 = 15

<em>7 boys go to the nursery in the afternoon.</em>

Boys + Girls = 15

Girls (Afternoon) = 15 - Boys = 15 - 7 = 8

<em>Work out how many girls go to the nursery in the morning.</em>

Girls (Morning) + Girls (Afternoon) = Girls (Total)

Girls (Morning)  + 8 = 24

Girls (Morning) = 24 - 8

Girls (Morning)  = 16
