The equation that is not necessarily true is that PQ = AB.

<h3>How to illustrate the equation?</h3>

The perpendicular bisector of any line segment can be drawn by opening the compass more than half, by putting the nib of the compass at one end of a line segment, and by marking an arc on both sides of the line segment from both the ends of the segment.

The following Property that the perpendicular bisector PQ follows when it bisects the line segment AB include:

  • AP=BP
  • AQ=BQ
  • AR=BR
  • ∠ARP=∠BRP=∠ARQ=∠BRQ=90°

Therefore, PQ is Perpendicular Bisector of Line Segment AB is not true.

Answer:

2.4 cans cost 47.4

If you cannot buy 2.4 cans, you must buy 3 cans, then you'll pay 59.25

Step-by-step explanation:

The lawn has trapezoidal shape, so find the area of the trapezoid using formula

A=\text{Midline}\times \text{Height}

In the diagram, ABED is rectangle, so BE = 12 m, thus ED = 20 m - 12 m = 8 m.

Consider right triangle EDC. By the Pythagorean theorem,

ED^2+EC^2=CD^2\\ \\ED^2+8^2=17^2\\ \\ED^2=289-64\\ \\ED^2=225\\ \\ED=15\ m

Thue,

Height = 15 m

Find the midline:

\text{Midline}=\dfrac{AD+BC}{2}=\dfrac{12+20}{2}=16\ m

Hence,

A=16\cdot 15=240\ m^2

One can cover 100\ m^2, to cover 240\ m^2 is needed

240:100=2.4 cans

One can costs 19.75, so 2.4 cans cost

19.75\cdot 2.4=47.4

If you cannot buy 2.4 cans, you must buy 3 cans, then you'll pay

19.75\cdot 3=59.25

Answer:

4 and 5

Step-by-step explanation:

n + 1 > 4

n > 4 - 1

n > 3

For the set { 1, 2 , 3 , 4, 5 }, 4 and 5 are greater than 3.

Hence, 4 and 5 makes the inequality n + 1 > 4 true.

the blank is 62
now simplify them for 2nd blank snce notheing else changed
2nd blank is 248
3rd blank is another simplification or 300-248 or 52

1st blank is 62
2nd blank is 248
