Answer:
in standard form: 641000000
in scientific form: 6.41 * 10^8
Step-by-step explanation:
hi again :)
first, make each term into standard form: (6.7 * 10^8) = 670000000 and (2.9 * 10^7) = 29000000
670000000 - 29000000 = 641000000
in scientific notation: 641000000 = 6.41 * 10^8
hope this helps! <3
Answer:
2
Step-by-step explanation:
Dividing by fractions is the same as multiplying by its reciprocal. So 8/6 divided by 4/6 is the same as 8/6 times 6/4
You can then solve this two ways.
1) Multiply like normal and simplify:
(8/6)(6/4) = 48/24 = 2.
2) Since there is a 6 in both the numerator and denominator, they cancel each other out. This leaves you with:
(8/1)(1/4). Multiply across like normal to get 8/4 = 2.
Answer:
∠1, ∠5 and ∠8 (a)
Step-by-step explanation:
∠1 because vertical angles are congruent
∠5 because opposite interior angles are congruent
if ∠5 = 70° then ∠8 also equals 70° because of vertical angles
