4 teaspoons because there are 3 teaspoons in 1 tablespoon
To be able to arrange the volumes from least to greatest we must be mindful that the exponent of 10 in the scientific notation should be arranged from least to greatest also. If two or more items have the same exponents in the 10 of the scientific notation, we use the base for comparison. For this item, the arrangement should be
2.2x10^12 km³, 6.9x10^12 km³, 2.7x10^18 km³, and 4.9x10^21 km³
Thus, the answer to this item is letter B.
Answer:
5b + ab - 14
Step-by-step explanation:
Answer:
0.155
Step-by-step explanation:
nth term of a geometric sequence = ar^n-1
Where,
a = first term
r = common ratio
n = number of terms
Given:
100, 80, 64,...
a = 100
r= 80/100
= 4/5
30th term of a geometric sequence = ar^30-1
= ar^29
= 100 × (4/5)^29
= 100 × (0.8)^29
= 100 × 0.00155
= 0.155
Therefore,
30th term of the geometric progression = 0.155
