Given:
Oil flow: n(t) = 7t where t is time and n = how far the oil is spreading
Area of the circular pattern the oil is forming:
A(n) = πn²
<span>Part A: Find the area of the circle of spilled oil as a function of time, or A[n(t)]
A[n(t)] = </span>π (7t)² = π * 49 * t²
<span>How large is the area of spilled oil after 8 minutes?
n(t) = 7t </span>→ 7 * 8 = 56
A(56) = 3.14 * 56² = 9,847.04 square units
or
A[n(t)] = π (7t)²
A[n(8)] = 3.14 * (7*8)² = 3.14 * 3,136 = 9,847.04 square units
Answer:
<em>Answer: A'Reana's weekly allowance is $100</em>
Step-by-step explanation:
<u>Backward Solution</u>
To solve some problems, we can work backward, using the inverse operations, to arrive at the solution.
The problem explains a sequence of expenses A'Reana does with her weekly allowance. In the end, she had $37.50.
That final balance came when she last spent $7.50 on a pizza. Thus, before that, she had $37.50+$7.50=$45
This balance is half of her previously remaining money. The other half was spent on a new shirt. Thus she had 2*$45=$90.
Those $90 were left after she gave $10 to her friend Taylor, thus, the initial money was $90+$10 = $100
Answer: A'Reana's weekly allowance is $100
Answer:
Step-by-step explanation:
42 > 24
24 < 42
Answer: Recuerda, una fracción representa las partes de la unidad. ... Para pasar una fracción impropia a número mixto debes dividir el numerador entre el denominador, después la parte entera será el cociente y la fracción propia estará formada por el resto y el divisor.
Is there a ratio? bc that doesnt look like the full question
