Answer:
6.0 miles
Step-by-step explanation:
The sequence of distances is a geometric sequence with first term a1 and common ratio (1 +10%) = 1.10. The sum of 7 terms of the sequence is ...
S7 = a1·(r^7 -1)/(r -1)
56.923 = a1·(1.1^7 -1)/(1.1 -1)
5.6923 = a1·0.9487171
Dividing by the coefficient of a1 gives its value:
5.6923/0.9487171 ≈ 5.999997 ≈ 6.000
The hiker traveled 6.0 miles on the first day.
C.) 344.50
Take what she paid before tax (325) and multiply it by 1.06 (the tax rate) and there's your answer.
They have the same absolute value because all opposites have the same absolut value because they both are the same distance from zero
Answer:
10number for a is a answer of that question
The lengths of the sides of the triangle:
No sides are equal to each other, so it's a scalene triangle.
Check if the sides satisfy the Pythagorean theorem:
They do, so it's a right triangle.
The triangle is a
right scalene triangle.
