The density of the material DOES NOT CHANGE when the block is cut into pieces:
density = m/v
= 3 gm/cm3
5x + 87 is the same angle measure as 10x + 17
5x + 87 = 10x+17 solve for x
..... and spend some more time studying grammar and spelling. There are at least 6 mistakes in your small post!
APPROXIMATELY
Yes in US ~~ 75% Yes in GB ~~ 25%
75% - 25% = ...............
Angle T = 43
tan (43) = opp / adj = gh/52 solve for gh
Angle t = 33
cos 33 = adj / hyp = 82 / gt solve for gt
Slope of given line = m = -1/3
New line thru point (-7,2)
y-2 = -1/3 (x +7) now manipulate this to the requested form to fin A and B ..................
6% money to be made 2000 (.06)(4) = 480 dollars
7% 2000(1 + .07/4)16 - 2000 = 639.86 dollars
interst rate per PERIOD = .07/4 periods = quarterly for 4 years = 16
x+y=4
xy=7
1/x +1/y = ? get common denominator
(x+y)/xy =?
= 4/7
7 correct and 7 incorrect = 14 problems so far and this is equal to 1/3 of her homework
3 * 14 = 42 problems in all
Ate 3/4 of the number....only 1/4 remains and the remains = 7
1/4 x = 7 multily both sides by 4
x = 28
