Answer:
Step-by-step explanation:
Use division. It was the same amount each day.
100 dollars over 4 days.
100 / 4 = 25
Each day her bank account decreased by 25 dollars.
Answer:
$3.70
Step-by-step explanation:
3.20+1.60=4.80
8.50-4.80=3.70
Imagine that we cut the cone in half with a vertical plane. In this plane we'd see points a, b and c. We need to find the measure of angle bca, and then double that angle, to obtain the answer to this problem.
Note that tan (angle bca) = opp / adj = 2 / 6, or 1/3, or 0.333...
Working backwards to find angle bca, we use the inverse tangent function:
arctan 0.3333.. = approx. 0.322 radians, or 18.435 degrees.
Doubling that gives us the measurement of the angle formed between the line segments: 2(18.435 deg) = 36.9 degrees, approximately.
7% =73.5
33%=346.5
$1050 - $346.5 =703.5
$703.5 + $73.5 = $777
