C is the closet to the real answer and its a estimate so, C
A trapezoid is isosceles if and only if
(1) The base angles are congruent
(2) The diagonals are congruent
(3) The opposite angles are supplementary
So the description does not guarantee that a trapezoid is isoceles for "Congruent bases".
Answer:
k+2 or k=2
Step-by-step explanation:
combine -5 and 7 to get your answer
Answer:
x=15
y=18
Step-by-step explanation:
then x+y=33
and 2x+5y=120
then x=33–y
since 2x+5y=120
then 2(33–y)+5y=120
then 66–2y+5y=120
then 66+3y=120
then 3y=120–66
then 3y=54
then y=54/3
then y=18
then x=33–18=15
Answer:
This number can be found using the Rule of 70, which describes the formula dt = 70 / r, where dt is the doubling time, and r is the annual rate of growth.
Step-by-step explanation:
24/6 = 4
20 x 2 = 40 x 2 = 80 x 2 = 160 x 2 = 320
20 ---> 320 in the first day.
Keep doing this equation. Multiply each day's end result by 2 four times for 9 more days.
