Answer: 5/(2)^9
Step-by-step explanation:
(40^7)/(2^30 x 25^3)=
(2*2*2*5)^7 / (2^30 x (5*5)^3)=
(2^7 * 2^7 * 2^7 * 5^7) / (2^30 x 5^3 * 5^3)=
(2^(7+7+7) * 5^7) / (2^30 x 5^(3+3))=
(2^21 * 5^7) / (2^30 x 5^6)=
2^(-9) * 5^1=5/(2)^9
A+B+C=$408
C+7
x+x+5
You can use these examples to find the word problem answer.
The answer: Time= Distance divide Speed.
Speed= 675,000 divide 900= 750 minutes. Convert that to hours and that leaves you with 12 hours and a half. If these questions are bothering you, just revise them- they’re speed distance time equations and i’d be blessed if they come up in my maths exam tomorrow.
