Answer:
D
Step-by-step explanation:
(7 × 10-7) × 0.06
7 × 0.06 × 10^-7
0.42 × 10^-7
4.2 × 10^-8
9t - 3t + 4
= 6t + 4
(hence 9-3)
you can do this due to the t being the same unit (classified as a like term). if it were 9t - 3g + 4, it would have to stay the same.
I am pretty sure the answer is: 1.79%
Answer:
D
Step-by-step explanation:
The diagonals of a rhombus bisect the angles, thus
∠ ABC = ∠ CBD = 5x - 18 and
∠ BAC = ∠ DAC = x
The diagonals are perpendicular bisectors of each other, thus
the angles round the intersection of the diagonals = 90°
Consider the triangle on the left of the rhombus, then
5x - 18 + x + 90 = 180 ( sum of angles in a triangle )
6x + 72 = 180 ( subtract 72 from both sides )
6x = 108 ( divide both sides by 6 )
x = 18 → D
Answer:
5 hours, y= how much money it will cost, and x represents how many hours
Step-by-step explanation:
y= 15x+45
120= 15x+45
-45 -45
75= 15x
75/15×= 5 hours
