Xavier is using square tiles to cover a table top. The tiles are 1 1/2in. On each side. The table top is 7 1/2 inches wide and 13 1/2 inches long. How many tiles dose Xavier need to use to cover the whole table?

45 Tiles

Step-by-step explanation:

7 1/2 × 13 1/2 = 101 1/4

Area = 101 1/4

1 1/12 × 1 1/2 = 2 1/4

Tile Area = 2 1/4

101 1/4 ÷ 2 1/4 = 45

good luck, i hope this helps :)

x = central angle apc = measure of minor arc ac

the two angles x and 30 add to 180, so x+30 = 180 and x = 180-30 = 150. the measure of minor arc ac is 150 degrees.

what we need to do from here is find the circumference and then multiply it by x/360 since there are 360 degrees in a circle. in this case, x = 150, so x/360 = 150/360 = 15/36 = 5/12. the shortest distance along the curve from a to c is 5/12 of the distance around the entire circle (aka circumference)

c = circumference

c = pi*d

c = pi*24

c = 24pi

now multiply this by 5/12 to get

distance along minor arc ac = (5/12)*(circumference)

distance along minor arc ac = (5/12)*(24pi)

distance along minor arc ac = 10pi

the formula you can use is

l = (x/360)*pi*d

with

l = length of minor arc

x = central angle

d = diameter

which essentially is the steps we took though a bit differently.

step-by-step explanation:

once you graph it hit 2nd (the blue button) and graph

that takes you to a table of coordinates

on the left is x coordinates and on the right is y coordinates and an empty box

(you may have to scroll up/down in order to get ( x, 0)
