Answer:
1) 6
2) 9
3) 80
4) 10
5) 4
6) 4
Step-by-step explanation:
1) 36 / 6 = 6
2) 45 / 5 = 9
3) 10 * 8 = 80
4) 5 * 2 = 10
5) 16 / 4 = 4
6) 12 / 3 = 4

Answer:
7/9
Step-by-step explanation:
Think of 1 as being 9/9. The difference between 9/9 and 2/9 is 7/9, which is the answer
Answer: 0.3m/s
Step-by-step explanation:
Height/ velocity
3m/12m per sec
Time= 0.25metres per seconds
To the nearest tenth, 0.3m per seconds
1 + tan ² Ф=sec²Ф
1+(12/5)²=sec²Ф
169/25=sec² Ф
sec Ф=⁺₋√(169/25)=⁺₋13/5
sec Ф=1/cos Ф ⇒cosФ=1/sec Ф
cos Ф>0 ⇔ sec Ф>0 ⇔ sec Ф=+ 13/5
cos Ф=1/secФ
cos Ф=1 / 13/5=5/13
we can calculate the sin Ф, with this method.
sin²Ф + cos²Ф=1 ⇒ sin Ф=⁺₋√(1-cos² Ф)
sin Ф=⁺₋√[1-(5/13)²]=⁺₋12/13
like cos Ф>0 and tan Ф>0 ⇒ sin Ф>0 ⇒sin Ф=12/13
answer: d.12/13
other method
tan Ф=sin Ф / cos Ф
12/5=sin Ф / 5/13
sin Ф=(12/5)*(5/13)=12/13
answer: d.12/13
