1/10 of the counters in a bag are blue. 1/2 of the counters are red. 2/5 of the counters are yellow. Which of the ratios below shows the ratio of blue to red to yellow?

Answers

Answer:

well 1/10 are blue, 5/10 are red, and 4/10 are yellow.

1/10 blue

5/10 red

4/10 yellow

I don't really know how to answer this question but I hope me converting the ratios helps :)

Step-by-step explanation:

Given: 1/10 blue
1/2 red
2/5 yellow


First, make it so that each if their whole (denominator, or the right side) is equal.

We already know that 2 and 5 are common factors of 10, so we get them to the number 10 by equal multiplication.


1/10 - blue
1/2(5) = 5/10 - red
2/5(2) = 4/10 - yellow

Now just take their numbers in order.

Answer:

$76.32

Step-by-step explanation:

First, add up all the costs for everything:

17 + 30 + 25 = 72

Now, we need to add the sales tax. To do this we multiply 72 by 1.06. This is because the sales tax is 6% (the decimal form of 6% is 0.06), and we add it on to the 100% cost (which is 1 in decimal form).

(72)(1.06) = 76.32

Therefore the total cost of everything Walter bought plus the tax rate is $76.32.

I hope this helps!!

If the exponential model f(x)=14(5)x is written with the base e, it will take the form A0ekx. What is A0 and what is k?

Answers

Answer:

We have:

f(x) = 14*(5)^x

And we want to write this in the form:

g(x) = A*e^(k*x)

We want to have f(x) = g(x)

This is ratter easy.

The general case is:

A*(r)^x = B*e^(k*x)

Here we have:

A = B

Then:

(r)^x = e^(k*x)

Now we can remember the relation:

(a^x)^y = a^(x*y)

Then we can write:

e^(k*x) = (e^k)^x

Then we have:

(r)^x = (e^k)^x

Then we must have:

r = e^k

Now let's go to our case:

14*(5)^x = A*e^(k*x) = A*(e^k)^x

Then we have:

14 = A

5 = (e^k)

With this equation we can find the value of k.

ln(5) = ln(e^k) = k

ln(5) = k

Then the equation g(x) is:

g(x) = 14*e^(ln(5)*x)

Answer:

A0=14 k +ln9

Step-by-step explanation:

To rewrite the model with the base e, we use the fact that for all b>0,

b=eln(b)

Using this property, and then the power property of logarithms, on 9x, we find that

(9)x=eln(9x)=exln(9)=e(ln(9))x

So we find that

14(9)x=14eln(9)x

So A0=14 and k=ln(9).
