Jake travel to the coffee shop by bike with speed of 8mph is  56mile and when bike got a flat so Jake walked 4mile

How to find the speed by biking and walking ?

let b = time spent biking

then   8-b =time spent walking

Write distance equation

dist=speed *time

So bike distance + walk distance =60mile

8b+4(8-b)=60\\8b+32-4b=60\\4b=60-32\\b=28/4\\\\b=7hrs

Then 8-7=1 hrs spent walking.

For cross check the answer find that actual distance for each

8(7)=56mi\\4(1)=4mi\\-------\\total distance=60mile

What is the length of the hypotenuse? If necessary, round to the nearest tenth.
PolarNik [594]

Answer:

hypotenuse = 25 yards

Step-by-step explanation:

Use pythagorean theorem

c^2 = a^2 + b^2      where c = hypotenuse and  'a' and 'b' are the legs

hyp^2 = 24^2  + 7^2

hyp^2 = 625

hyp = 25 yd

14. A group of crafters is collecting data on the amount of yarn they use for each scarf knitted. Each person collected 12 piece
fgiga [73]

Answer:

D. There is not enough information to make a conclusion about the population mean.

Step-by-step explanation:

One of the crafters Chris has a sample means of 200. This means that the average amount of yarn Chris used is 200 meters. Yet there is nothing else given about the other crafters, hence it is impossible to draw a conclusion.

if $5,000,000 isinvested at 4% interest compunded continuously, how much willl the investment be worth in 30 years
Katarina [22]
The answer is $16216987.55 (IMPORTANT: This is the answer assuming that the interest rate is annually. The quesiton says 'continuously' so I was a bit confused)

To solve this problem, you can use the compound interest formula. 

Here it is once you plug in the numbers: A = 5,000,000 ( 1 + .04) ^30

Just solve the equation to find the solution.
