Answer:

8.1 = LM

Step-by-step explanation:

(whole secant) x (external part) = (tangent)^2

13 * 5 = LM^2

65 = LM^2

sqrt(65) = LM

8.06225 = LM

To one decimal place

8.1 = LM

Find the percent cost of the total spent on each:

natta225 [31]

The right answer is 18%,61%,21%

Step-by-step explanation:

Given,

Amount spent on equipment = $46

Amount spent on fees = $152

Transportation = $52

Total spent = Equipment + Fees + Transport

Total spent = 46+152+52 = $250

Percent spent on equipment = $\frac{Amount\ spent\ on\ equipment}{Total\ spent}*100$

Percent spent on equipment = $\frac{46}{250}*100 = 18.4\%$

Rounding off to nearest percent

Percent spent on equipment = 18%

Percent spent on fees = $\frac{Amount\ of\ fees}{Total\ spent}*100$

Percent spent on fees = $\frac{152}{250}*100 = 60.8\%$

Rounding off to nearest whole percent

Percent spent on fees = 61%

Percent spent on transportation = $\frac{Amount\ spent\ on\ transportation}{Total\ spent}*100$

Percent spent on transportation = $\frac{52}{250}*100 = 20.8\%$

Rounding off to nearest whole percent

Percent spent on transportation = 21%

The right answer is 18%,61%,21%

Answer the multiple choice question

elixir [45]

Answer:

200

Step-by-step explanation:

There are 6 numbers on a standard number cube. If the rolling is random, there should be a 1/6 chance of rolling a certain number. Basically, someone would theoretically roll each number 100 times out of 600. Because there are two numbers on the dice greater than 4, multiply 100 by 2 to find the answer.

The simple interest formula is A = P(1 + r)t where P represents the amount originally deposited, r is the interest rate, and A i

xxMikexx [17]

To find this, you just need to plug it in and use some algebra to figure it out.
Initial:   2700 = 2200(1 + r)5
multiply 2200 and 5:    2700 = 11000(1 + r)
Divide both sides by 11000: .24 = 1 + r
subtract both sides by 1: -.754 = r

The problem is, a negative interest rate makes no sense if there was actually an increase of 500. We can try distributing the 11000 instead
Where we left off:    2700 = 11000(1 + r)
Distribute the 11000: 2700 = 11000 + 11000r
Subtract 11000 from both sides: -8300 = 11000r
Divide both sides by 11000: -.754 = r

As you can see, both methods reached the same impossible answer. I'm assuming that you didn't type out the equation right. Are you sure it wasn't
2700 = 2200(1 - r)5
? If you subtract the r to make it negative, it might make more sense. But that still leaves us with a .754 rate of interest, which seems too high. Double check where you're typing from

Solve: 12^x2+5x-4 =12^2x+6

Answer:

x=2, x=-5

Step-by-step explanation:

to work more comfortably, the first thing we need to do is work the equation linearly, for that we take advantage of the property of logarithms that tells me that $log(a^{b})=b*log(a)$
