420km
405km
210km
200km
Correct answer is D
1 litre = N63.00
xlitres = N900.00
x x N63 = N900 x 1 litre
x = \(\frac{900}{63} \times litre\)
x = \(\frac{100}{7}\) litres
Also, 1 litre = 14km
\(\frac{100}{7}\) = y
y x 1 litre = \(\frac{100litre}{7}\) x 14km
y = 20km
(x - y)(1 - a)
(x + y)(1 + a)
(x + y)(1 - a)
(x - y)(1 + a)
Correct answer is C
x + y - ax = ay
= (x + y) -a(x + y) = (x + y)(1 - a)
Simplify 0.000215 x 0.000028 and express your answer in standard form
6.03 x 109
6.02 x 109
6.03 x 10-9
6.02 x 10-9
Correct answer is D
0.000215215 x 0.000028
= 215 x 10-4 x 28 x 10-4
= 215 x 28 x 10-6-6
= 6020 x 10-12
= 6.020 x 103 x 10-12
= 6.02 x 103 - 12
= 6.02 x 10-9
Find the value of x in the diagram
50o
60o
70o
80o
Correct answer is C
30 + x = 100
x = 100 - 30
= 70o
