Answer:
A= 4.5×10^11
B= 3.5×10^3
Step-by-step explanation:
A
(5×10^3)= 5000
(9×10^7)=90000000
multiply both of them
=450000000000 or 4.5×10^11
B
(7×10^5)=700000
(2×10^2)=200
700000÷200
3500 or 3.5×10^3
Answer:
x = 18
Step-by-step explanation:
So since a || b,
7x + 11 = 10x - 43
3x = 54
x = 18
Answer: y = 2x + 50
Step-by-step explanation:
first find the slope (m):
slope = rise/run = y1-y2/x1-x2
(1,52); (2,54)
slope = (54-52)/(2-1) = 2/1 = 2; m = 2
now since we have the slope and a point, we will put it into point-slope form:
y = m(x - x1) + y1
y = 2(x - 3) + 56
y = 2x - 6 + 56
y = 2x + 50
Answer:
120 degrees
Step-by-step explanation:
Remember that the interior angles of a triangle always add up to 180 degrees. We know that two of the angles (45 and 15) add up to 60 degrees. Now we just have to subtract the 60 degrees we have from the 180 degree total in order to get the measure of the missing angle.
180 - 60 = 120
Therefore... the answer is 120 degrees
