A builder makes staircases where each step is 28 cm long and rises 18 cm so people don't trip. Every
staircase has a stringer - a diagonal support connecting all of the steps.

stringer
A certain staircase will have 6 steps.
What is the length of the stringer for this staircase?
Round your answer to the nearest tenth of a centimeter.

Step-by-step explanation:

The length of a strip - obtained from Pythagoras is

We need 6 of these strips.

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
