The following circle graph represents first-quarter absences of Washington Middle School students. If 96 students had two or mor

UkoKoshka [18]

How many students had 3 or more absences? Add together {45%, 21%, 23%} and subtract that sum from 100%: 11%.

How many students had two or more absences? Add together this 11% and 21%: 32% had two or more absences. Let the total number of students be n. Then 32% of these n students add up to 96 students. Thus, 0.32n = 96, and n= 300.

How many students had one absence? The chart shows that that is 45%, and we know that there are 300 students total.

Thus, the number of students who had one absence was 0.45(300) = 135.

A circular oil slick is expanding at a rate of 3m/min. How fast is the area of the oil slick changing when the diameter is 48 me

olga55 [171]

Answer:

$48\pi \:m/min$

Step-by-step explanation:

Diameter = 48 m

Therefore radius r = 48/2 = 24 m

$Area \: of \: circular \: oil \: slick \\ A = \pi {r}^{2} \\ differentiating \: w \: r \: to \: t \: on \: \\ both \: sides \\ \\ \frac{dA}{dt} = \frac{d}{dt} (\pi {r}^{2} )\\ \\ \frac{dA}{dt} =\pi \frac{d}{dt} {r}^{2} \\ \\ \frac{dA}{dt} =\pi \times 2{r}\\ \\ \frac{dA}{dt} =2\pi {r} \\ \\ \bigg(\frac{dA}{dt} \bigg)_{r=24} =2\pi \times {24} \\ \\ \bigg(\frac{dA}{dt} \bigg)_{r=24} =48\pi \: m \: per \: min$
