Since there only 3 colors you add 12/20(Red) + 6/12(Blue) and get 18/20(Combined Red and Blue)

Then you take out the Combined red and blue from the total percentage or 20/20(All 3 Combined/Full spinner)-18/20(Combined red+blue)=2/20

The answer is A.2/20

1. Charlie bought a new computer for $450 with his credit card. He plans to pay the minimum payment
atroni [7]

Given:

Charlie bought a new computer for $450 with his credit card.

He plans to pay the minimum payment  of $25 per month.

To find:

The rate of change.

Solution:

Let y be the remaining amount of loan after x months.

Initial amount of loan = $450

Payment of one month = $25

Payment of x months = $25x

Now,

Remining amount = Initial amount of loan - Payment of x months

y=450-25x     ...(i)

The slope intercept form is

y=mx+b     ...(ii)

where, m is slope and b is y-intercept.

From (i) and (ii), we get

m=-25

Therefore, the rate of change is -25 dollars.

Solve for e. T=e29<br><br><br> ​​ e=±3T√T<br><br> e=±3T<br><br> e=±3T√<br><br> ​ e=±9T√ ​
Anon25 [30]

Answer:

option (3) is correct.

e= \pm 3\sqrt{T}

Step-by-step explanation:

Given T=\frac{e^2}{9}

We have to solve for e.

Consider the given statement,

T=\frac{e^2}{9}

Cross multiply, we get,

\Rightarrow 9T={e^2}

Taking square root both sides , we get,

\Rightarrow \sqrt{9T}=e

We know square root of 9 is 3.

\Rightarrow \pm 3\sqrt{T}=e

Thus, option (3) is correct.

e= \pm 3\sqrt{T}
