<span>Which number produces a rational number when added to 0.5 ?</span>
Answer:
44.1 x 10^-2
Step-by-step explanation:
Since one grain
= 7 x 10^-5
6300kg = 7 x 10^-5 x 6300
Put 6300 in standard form
7 x 10^-5 x 6.3 x 10^3
Multiply the whole numbers and add the exponents
7 x 6.3 x 10^-5 + 3
44.1 x 10^-2
There are 44.1 x 10^-2 grains of sand in 6300kg
Answer:
.
Step-by-step explanation:
DC = 16 and
DB = 30 so
CB = 14
DB = 30 and
EB = 49 so
EB = 19
Answer:
-8x+12
Step-by-step explanation:
1. You need to distribute the (-1) from outside the bracket onto all the terms in the bracket, which includes (8x) and (-12). If there is a minus outside the bracket and one minus in the bracket, the operation would be a plus and vice versa. If there is a minus outside the bracket and one plus in the bracket, the operation would be a minus and vice versa.
- (8x - 12) = (-1) × (8x) + (-1) × (-12)
= -8x + (+12)
= -8x + 12
