On the day of the field trip, each teacher must call the parents of any student who has not returned a
permission slip. all of mr. gomez's students returned their permission slips, so he did not have to make any
calls. mrs. hooper and mr. anderson had to call a total of eight parents. mrs. hooper needed to call two more
students than mr. anderson. which set of equations correctly describes the phone calls made? (let h = mrs.
hooper's calls and a = mr. anderson's calls.)

is means division by fractions

step-by-step explanation:

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
