How do you put decimals into an average

answer:

d

step-by-step explanation:

since the triangle is right use the sine ratio to find x

sin65° = =

multiply both sides by x

x × sin65° = 22 ( divide both sides by sin65° )

x = ≈ 24.27 cm → d

there are 4 sides to this figure (trapezoid). the left slanted side and the right most vertical side, combined with the top and bottom horizontal sides, will get us the perimeter.

left slanted side = 5 yards

right most vertical side = 4 yards (see note below)

bottom side = 9 yards

top side = 6 yards

add up the four sides mentioned: 5+4+9+6 = 9+15 = 24

note: the rectangle has opposite sides that are the same length. while the right most side isn't labeled, it is the same length as the left side of the rectangle, so both are 4 yards long.

another thing i should probably mention is that we do not add in the interior 4 yard side. the perimeter is only the outer or exterior sides we care about. think of it like we're trying to fence around some property lot and we don't want to subdivide the property up. finding the perimeter will us find the amount of fencing needed to surround the property.

answer:

5/6

step-by-step explanation:

1/2 + 1/3

the common denominator is 6

1/2 *3/3 = 3/6

1/3 *2/2 = 2/6

3/6+2/6

5/6
