Answer:
The answer is Graph B
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
Cos(D) = adjacent / hypotenuse
The adjacent side is the one making up angle D
adjacent side = f
hypotenuse = e
Cos(D) = f/e
D = cos-1(f/e)
Answer:
10 feet
Step-by-step explanation:
Drawing obviously not to scale but... Red segment is the ruler, at least the part between 5 and 6 inches, 1 inch long. Brown segment is the pole, ground to the top. Leftmost point is the eye, green line is the horizontal. The triangles are similar (AAA, the vertical lines are parallel), the ratio of the side is the same as the ratio of the heights. The height of the larger triangle (measured across the green line is
.
Ratio of the height is then .
At this point the height of the pole is 60 times the length of the measure on the ruler, or 60 inches, that is 5 feet. Add the 5 feet the pole was starting from, it's 10 feet.
Answer: $5780
Step-by-step explanation:
Mrs. Jackson gave sum of money to her son and daughter in the ratio 8:9 and her daughter received $3,060. To get the total amount given to the children goes thus:
Son = 8
Daughter= 9
Total = 8+9 = 17
Let the total amount given to the children be y. Since the daughter's share is $3060.
= 9/17 × y = 3060
= 9y/17 = 3060
9y = 3060 × 17
9y = 52020
y = 52020/9
y = 5780
Mrs Jackson gave out $5780
F=ar^t if the half-life is 96 years...
.5=r^96
ln(.5)=96lnr
ln(.5)/96=lnr
r=e^((ln.5)/96)
f=800e^(336(ln.5)/96)
f=70.71
So about 71mg will remain after 336 years.
