Answer:
It should be 160 degrees as well.
Step-by-step explanation:
The opposite angles of one another in parallelograms are equals
you keep the 2k
so 5(-45)5x is 5 * -45*5 = -1125
the answer is 2k+-1125x
10! If you use the trapezoid area formula and plug in the known values, just solve for h(height)
2/7x - 2/5x = 8
multiply both sides by 35
= 10x - 14x = 280
combine 10x and 14x
= -4x = 280
divide both sides by -4
x= -70
9514 1404 393
Answer:
about 145.3 mg
Step-by-step explanation:
If half breaks down in the hour, then half remains. That is, each hour the amount remaining is multiplied by 1/2. The remainder after 6 hours is ...
(9300 mg)(1/2)^6 = 145.3125 gm
About 145.3 mg will be left after 6 hours.
