A school with a population of 2,500 students experiences a flu outbreak. It is found that the number of healthy students at the school is decreasing at a rate of 15% each day. Which function can be used to find the number of healthy students at the school d days after the outbreak begins?
Answer:
y=2500(0.85)^d
Step-by-step explanation:
Seeing as there are no option choices, I shall digress.
Because of a decrease of 15% each day, it means exponential decay. Using the formula y=a(1-r)^x, we have y=2500(1-0.15)^d -> y=2500(0.85)^d
Your function would thus be y=2500(0.85)^d
Answer:
The function that can be used is x = (2500 × 0.15)(number of days, or d)
Step-by-step explanation:
First we can create an equation to find this easier. We can say that x, or the number of infected students, is equal to (2500 × 0.15), since percentages are easily changed into decimals, and multiply that by the number of days or d.
You buy a day pass to use the subway for $5. After buying the pass, you pay $2 per ride. Write an equation to describe how much money, y, you pay to ride x number of rides.
Hi there!
So here says that when I buy a day pass using the subway I pay $5 and $2 per ride.
This means that it’ll be $7 per ride.
y=7
x=1
So for every 1 ride on the subway, I have to spend $7.

what is f(5) f(x)=3x+2
════════ ∘◦❁◦∘ ════════
Answer : 17════════════════════
Known thatf(x) = 3x + 2
════════════════════
Questionf(5) = ..?
════════════════════
Way to do#since the x inside (x) change into (5), then just change the x with (5)
f(x) = 3x + 2
f(5) = 3(5) + 2
f(5) = 15 + 2
f(5) = 17

Convert the measurement. Round to the nearest hundredth.
12 feet = meters
Answer:
3.7 metres
Step-by-step explanation:
1 foot = 0.305 metre
12 foot = 12 × 0.305
= 3.6576
Rounding the answer to nearest hundredth
3.6576 = 3.7000
= 3.7 metres

A student mixed 3/5 liter of citric acid solution. He used 1/6 of the citric acid solution for the experiment. How much of the citric acid solution did he use? Be sure the answer is in simplest form
Answer:
1 / 10 L
Step-by-step explanation:
Litres of citric acid solution = 3/5
Fraction of solution used = 1/6
1/6 of 3/5
1/6 * 3/5
= (1 * 3 / (6 * 5)
= 3 / 30
= 1/ 10

William left a 20% tip on a $15.80 lunch bill. How much did he pay for lunch?
Answer:
18.96
Step-by-step explanation:
15.8x120%=18.96
Answer:
the answer is 3.16 so 20 percent of 15.80 is 3.16
Step-by-step explanation:
15.80/100 = 0.158 and then 0.158 times 20 = 3.16 then 15.80 + 3.16 = 18.96 so the ANSWER IS $18.96

It takes Ebru 131313 minutes to bike to school. If she walks, it takes her twice as long. Ebru leaves for school at 7{:}157:157, colon, 15. What time will Ebru get to school if she walks?
Answer: 7:41 am
Step-by-step explanation:
It takes Ebru 13 minutes to bike to school but if she walks it would take her twice at long.
= 13 * 2
= 26 minutes
If she leaves the house at 7:15 , she will arrive at:
= 715 + 26
= 7:41 hours
Anthony has $11,600 in his account and earns $700 per month. He spends $8,000 on a car and has other expenses totaling $900 per month. How many months will go by before Anthony runs out of money?
Answer:
216 Months
Step-by-step explanation:
First find how much money he looses per month: 0+700-8000= -7300 on the first month. So 11600-7300=4300.
Then, he starts loosing $200 dollars per month because 900-700=200.
So 4300/20=215. So 215+1=216 months before Anthony runs out of money.
Answer: 16 months
Step-by-step explanation:
8000-11600=3600
700-900= -200monthly
200divide 3600= 16 months
Kalani has run 4 1/5 miles in 2/3 an hour. If he continues to run at this rate, how many miles will he run in one hour?
Answer:
Kalani will run 6.3 miles OR 6 3/10 miles.
Step-by-step explanation:
So first step that I would do is make it easier to understand by converting the fraction to a whole number. 2/3 hour= 40 minutes.
So Kalani runs 4 1/5 miles in 40 minutes.
Then, we convert 4 1/5 to 4.2. Next, I would divide 4.2 by 2 to get how long he ran in 20 minutes. 4.2/2=2.1.
The final step is to add 2.1 and 4.2 and we get 6.3.
Extra step:
But if we need to turn it back into a fraction, it would be 6 3/10
Hope this helps :)

The cheetah is the fastest land animal, capiable of attaining a speed of 110 km/h. In August 2009 , the world record for the men's 100m sprint was set at 9.58 seconds. How many times is a cheetah as fast as the fastest human sprinter?
Answer:
About 3 times faster
Step-by-step explanation:
Cheetah's speed = 110 km / hr
World 100m sprint record :
Speed of sprinter :
Distance / time
100 m / 9.58s
= 10.438413 m/s
Convert Cheetah's speed to m/s
110 km/hr = (110 * 1000)m / (60 * 60 s)
= 110000 m / 3600 s
= 30.55555 m/s
Number of times cheetah is faster than sprinter :
30.55555 m/s ÷ 10.438413 m/s
= 2.927 times
