Answer:
12
96
9
38
25
Step-by-step explanation:
<h3>i.a+7 for a=5</h3>
5+7=12
<h3>ii.8(c+3) for c =9</h3>
8(9+3)
8(12)
96
<h3>iii.n+8 divided by 4 for n=28</h3>
=28+8 divided by 4
=36 divided by 4
=9
<h3>iv.6p+40 divided by 5 for p =5</h3>
=6×5+40 divided by 5
=30+40 divided by 5
=70 divided by 5
=38
<h3>v.3x+7 for x=6</h3>
=3×6+7
=18+7
=25
Because one is put into fraction form. Therefore the one in fraction form is going to be smaller. 5*4=20 and 5*1/4=1.25. I hope my answer helped you.

Step-by-step explanation:
Rule for rounding :
You look at the number next to the place value you are meant to round and if the number is :
=
4 and below you round down.
5 and above you round up
Nearest hundred thousand: 100,000
This is because you look at the number next to the hundred thousand spot which is a 2 so you round down
Nearest ten thousand: 130,000
Same reason as before the number next to the 2 in the number is a 6. So you round up
Nearest thousand: 126,000
The number next to the thousandth place value is a 0 so you round down
Given that
3 cos 80° cosec 10° + 2 sin 59° sec 31°
⇛3 cos(90°-10°) cosec 10°+2 sin (90°-31°) sec 31°
We know that
sin (90° - A) = cos A
cos (90°-A) = sin A
⇛3 sin 10° cosec 10° + 2 cos 31° sec 31°
⇛3 sin 10° (1/sin 10°) + 2 cos 31° (1/cos 31°)
⇛3 (sin 10°/sin 10°) + 2 (cos 31°/cos 31°)
⇛3 (1) + 2(1)
⇛3+2
⇛5
