Answer:

m ABC = 270°

Step-by-step explanation:

Note that the measure of the circle = 360°

m CA = 90°, thus

m ABC = 360° - m CA = 360° - 90° = 270°

Answer:

Let O be the center of the circle.

<COA = 90*

<FOE = <AOB = 146*

Considering that a circle is 360* we have <BOC = 124*

The Arc ABC is <AOB + <BOC = 124 + 90 =214*.

The ratio of nitrogen to potassium in a sample to soil is 12:9. If the sample has 36 units of nitrogen, how much potassium does the sample have?

Answers

The ratio of nitrogen to potassium is said to be : 12 : 9
Now, the given sample for the units of nitrogen is 36.
Let's find out how much will be the value of potassium
.=> 12 : 9 = 36 : x , where x will be the value of the potassium.First, let's multiply the inner value of the proportion
=> 9 * 36 = 324
=> 324 / 12 = 27
Now, the ratio: 12 : 9 = 36 : 27

How do you calculate interest?

Answers

Well let’s say you put $100 in the bank. And they charge 10% interest. And 10% of $100 is 10. So it would be $10 interest.
use the simple interest calculator to find A, the final investment value, using the simple interest formula. A=P(1+rt) where P is the principal amount of money to be invested at an interest rate r% per period for t number of time periods. Where R is in decimal form; R=R/100; r and t are in the same units of time.
