Answer:
Step-by-step explanation:
The triangles are not similar. Looking at the diagram, triangle STU is smaller than triangle PQR. If they are similar, it would mean that
ST/PQ = TU/QR = SU/PR
This means that there would be a scale factor. Substituting, the values, it becomes
ST/PQ = 7/9 = 0.78
TU/QR = 10/15 = 0.67
SU/PR = 8/12 = 0.67
Therefore, since
ST/PQ ≠ TU/QR ≠ SU/PR
The triangles are not similar.
Answer:
1) c
2) D
3) H
Step-by-step explanation:
Just follow the graph as shown
It’s quite easy here.
A sum means addition.
The term “of a number” means youre dealing with a variable.
10 is an Interger. Put those two together and you end up with:
x+10
^^ Thats your answer. Hope this was helpful.
4x+11 is The answer
-2x-(-6x) two negatives make a positive so -2x-(-6x) is now -2x+6x
-2x+6x=4x
4-(-7) again two negatives make a positive so 4-(-7)
Is now 4+7
4+7=11

1.5581 m
Step-by-step explanation:
For every cycle, it takes 6 hours to get from a high to low tide and another 6 hours back to high tide.
The change in the height of the tide in meters is;
2.1 – 0. 8 = 1.3 m
Therefore for every 6 hours, the tides shift by 1.3 meters. The average change is;
1.3 m / 6 hr
= 0.217 m / hr
= 0.00361 m / min
At 9.30 am, the tides are rising from low tides of 6.00 am
9.30 – 6.00 = 3.30
3hrs 30 min
= 210 min
The rise of the tide at this time is by;
0.00361 * 210
= 0.7581 m
The height of the tides will therefore be;
0.8 m + 0.7581m
= 1.5581 m
