70 = 1 x 70, 2 x 35, 5 x 14, and 7 x 10. It is usually written as 1,2,5,7,10,14,35,70
86 = 1 x 86 or 2 x 43. It can be written as 1,2,43,86
154 = 1 x 154, 2 x 77, 7 x 22, 11 x 14. Can be written as 1,2,7,11,14,22,77,154
238 = 1 x 238, 2 x 119, 7 x 34, or 14 x 17. Can be written as 1,2,7,14,17,34,119,138
Total surface area
=[ 2πr x 11 ] + πr²
=[ 2 x (22/7) x 3.5 x 11 ] + 2[ (22/7) x 3.5² ]
=154 + 2(15.393)
=184.786 in²
Answer:
y = 3, x = 3
Step-by-step explanation:
5x – 3y = 6
5x = 6 + 3y
x = (6 + 3y)/5
3x + 4y= 21
3x = 21 - 4y
x = (21-4y)/3
Using simultaneous equations:
(21-4y)/3 = (6 + 3y)/5
--> 105-20y = 18 + 9y
29y = 87
Answer:
7
Step-by-step explanation:
2v ÷ e + 3
we want to find the value of the expression when v = 10 and e = 5
to do so we substitute the values into the expression
2v ÷ e + 3
==> substitute 10 for v and 5 for e
2(10) ÷ 5 + 3
We now evaluate using bpemdas
==> multiply 2 and 10
20 ÷ 5 + 3
==> divide 20 by 5
4 + 3
==> add 4 and 3
= 7
