Minutes(m) Cost
0 20
10 22
20 24
50 30
slope formula:
m = (y1 - y2) / (x1 - x2)
m = (20 - 22) / (0 - 10) = -2/-10 = 1/5 or 0.20
y = (1/5)(x) + 20
The rule that describes Amy's monthly cost is:
m = 1/5x + 20 or m = 0.20x + 20
Where x is the number of minutes spent on the call.
Answer:
ΔRMS ≅ ΔRQS by AAS
Step-by-step explanation:
See the diagram attached.
Given that ∠ RMS = ∠ RQS and N is any point on RS and ∠ MRS = ∠ SRQ.
Therefore, between Δ RMS and Δ RQS, we have
(i) ∠ RMS = ∠ RQS {Given}
(ii) ∠ MRS = ∠ SRQ {Also given} and
(iii) RS is the common side.
So, by angle-angle-side i.e. AAS criteria we can write ΔRMS ≅ ΔRQS. (Answer)
Answer:
2.5 or 2 1/2 in
Step-by-step explanation:
Area = width x length
width = area / length = 11.25 / 4.5 = 2.5
If I'm not wrong I believe it would be 343 different ways.
