3x = 72 /3
X = 24
X^3 = 72
X = (72)^(1/3)
X= 4.160167646
The area of a rhombus is the product of the diagonals divided by 2. In this question, the diagonals are given, so that's really easy. Let's convert the measures to meters, that'll help for the final area calculation:
Area of one rhombus: (0.52x0.30)/2 = 0.078 m²
In 60 m², you can fit 60/0.078 tiles. That's 769.23, rounded to 770 since you'll have to cut up the last tile.
C) $694.25
Why?
Because you want to times the interest by 2 (1 is for one year but u want to find the amount after two years) then you multiply the amount given to each bank separately so:
400*0.07 (7% which is 7/100) = 28
250*0.065 (6.5% which is 65/1000) = 16.25
Then u add the interests together:
28+16.25 = 44.25
Finally you add that to the amount you started with:
$650+$44.25= $694.25
A. Yes
B. Because the three inside angles of both triangles would be identical.
C. Set up a ratio:
121/22 = AB/30
Solve for AB:
AB = (121 * 30) / 22
AB = 3630 / 22
AB = 165 ft.
Domain = {x|x = 2, 9, 6}
Range = {y|y = c, 0}
I think this is the answer? I tried, it's better to fill it in than to leave it blank :/
