Answer:
Convert kilometres to metres. Since kilo- means 1 000, one kilometre (km) is equal to 1000 metres (m). Multiply the number of kilometres by 1 000 to get the same measurement in metres. For example, 75 kilometres =

Answer:
The answer is 16.
Step-by-step explanation:
First you need to substitute the letters with the number.
1 -2ab = -2(8)(-4)= 64 -2(8)=-16 -16(-4)=64 8-4= 4 64/4= 16A 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
explain how to find cot, sec, csc
Answer:
The cotangent of x is defined to be the cosine of x divided by the sine of x: cot x = cos x sin x . The secant of x is 1 divided by the cosine of x: sec x = 1 cos x , and the cosecant of x is defined to be 1 divided by the sine of x: csc x = 1 sin x . = tan 5π 4

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.
1+(1/(1+(1/(1+(1/x)))))

8n - 2(n+5) = -3 + 6n
Answer:
No solution
Step-by-step explanation:
There are no values of n that make the equation true.
8n −2(n+5) = −3 + 6n
First Step: Simplify both sides of the equation
(Distribute) 8n + (-2)(n) + (-2)(5) = -3 + 62
8n + -2n + -10 = -3 + 6n
(Combine like terms) (8n + −2n) + (−10) = 6n − 3
6n + −10 = 6n − 3
6n − 10 = 6n − 3
Step 2: Subtract 6n from both sides
6n − 10 − 6n = 6n − 3 − 6n
-10 = -3
Step 3: Add 10 to both sides
-10 + 10 = -3 + 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

The cost of manufacturing a printer is $35. The
retailer has a markup of 35%. What is the selling
price of the printer?
Show work plz
Answer:
$47.25
Step-by-step explanation:
First, we find how much the markup costs:
35%=35/100
So we do,
35/100x$35 = $12.25
To find the total price of everything, we have to add the price markup AND the original cost of the printer.
So we do, 35 + 12.25 = $47.25
I hope this helps!:)
What is the rate of change
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 :)

Helen's Shop is 60 meters wide and 80 meters long. The parking lot in front of Helen's Shop is twice as long as it is wide and is 50 meters wide.
Answer:
The sum of the area is 9800 m^2
Step-by-step explanation:
( A= L x W )
Helens shop, A=(60m)x(80m)=4800 m^2
Parking lot, A=2W x W = 2(50m) x (50m)=5000 m²
The sum is 9800 m^2.
