8/0.61=13.114… then round if needed
Answer:
2.8a²+0.9a - 1.2
Step-by-step explanation:
Given the expression 0.3(3a-4)-0.05(8a)(-7a)
Expand using the distributive law
0.3(3a-4)-0.05(8a)(-7a)
0.3(3a)-0.3(4)-0.05(8a)(-7a)
0.9a-1.2 - 0.05(8a)(-7a)
0.9a - 1.2 + 2.8a²
Rearrange
2.8a²+0.9a - 1.2
Hence the required expression is 2.8a²+0.9a - 1.2
A. first you can translate the lines 4 squares down.
then reflect the figure on th y line.
(attention: the rotation cant be done.)
B. yes they are. although we translated and reflected the figure l, we did not make any kind of change in size
good luck
There will be 38 grams remaining.
The equation would be of the form
y = a(1+r)ˣ, where a is the initial value, r is the rate as a decimal number, and x is the amount of time. Using our values from the problem, we have:
y = 670(1-0.273)^9 = 670(0.727)^9 = 38
Answer: X = 30*
All circles = 360*
we can subtract 260 from that because we know the length of one so we know the other is 130.
We are then left with only 100 and we know the two sides are equivalent so 100 / 2 = 50
