In a cave, a stalactite gets 4 millimeters longer each year. This year it is
72 centimeters
How many years until it is 1 meter long *25 points*

Answers

Answer 1

The number of years it will take until the stalactite is 1 meter long is; 70 years

How to convert units of measurements?

From conversion units, we know that;

1 m = 100 cm

1 cm = 100 m

Current length is given as 72 cm

Thus;

Length after x years = 1 m = 100 cm

Length increase in x years  = 100 -72 = 28 cm

Since 1 cm = 10 mm

Then;

Length increase in x years  in mm = 28 * 10 = 280 mm

Thus;

Length increase in 1 year = 4 mm

Length increase in x years = 4x mm

Then; 4x  = 280

x = 70

Thus, it will take 70 years  until it is 1 meter long.

Step-by-step explanation:

Every person has blood type O, A, B, or AB. A random group of people are blood-typed, and the results are shown in the table. A 2-column table with 4 rows is shown. The first column is labeled Blood Type with entries O, A, B, AB. The second column is labeled Number of People with entries 22, 20, 6, 2. Use the table to determine the following probabilities. The probability that a randomly chosen person from this group has type B is . The probability that a randomly chosen person from this group has type AB is . The probability that a randomly chosen person from this group has type B or type AB blood is

Answers

Answer:

3/25 for type B, 1/25 for type AB, and 4/25 for both

Step-by-step explanation:

O goes to 22

A goes to 20

B goes to 6

AB goes to 2

22+20+6+2 = 50, so (number of people with a certain blood type)/50 = the answers for each question.

7y - 9 = 2(y - 4) + 1​

Answers

Answer:

Step-by-step explanation:

Distribution comes first, so:

7y-9 = 2y-8+1

Then you simplify:

7y-9 = 2y-7

Then you subtract or add the lowest number with a letter:

5y-9 = -7

Now you get 5y alone, so we add the 9:

5y = 2

Then you divide 5y = 2 by 5

y = 2/5 or .4

Help plz. If u know the answer also show work for how you got it plz. Thanks!

Answers

The answer is 37. You use Pythagorean theorem so you get 5 squared + b squared= 13 squared. You’d get 25+ b squared= 169. You subtract 25 from 169 and you get b squared equals 144. You square root both the b and 144 and You would get 12 for that side. Then you do Pythagorean theorem again. You do 12 squared+ 35 squared= c squared. This would turn into 144+1,225= c squared this simplifies to 1,369= c squared. You square root both sides and you get your final answer 37

Answer:   choice F) 12 & 1/2 square yards.

=====================================================

We'll use this formula

a & b/c = (a*c + b)/c

to convert from a mixed number to an improper fraction.

Let's convert the first mixed number to an improper fraction

a & b/c = (a*c + b)/c

3 & 3/4 = (3*4 + 3)/4

3 & 3/4 = 15/4

Repeat the same idea for the second mixed number as well

a & b/c = (a*c + b)/c

3 & 1/3 = (3*3 + 1)/3

3 & 1/3 = 10/3

--------------------

In short we have

3 & 3/4 = 15/43 & 1/3 = 10/3

Doing these conversions is useful to be able to multiply the values like so:

(15/4)*(10/3) = (15*10)/(4*3) = 150/12 = (6*25)/(6*2) = 25/2

Now use your calculator to find that 25/2 = 12.5

We can then say....

12.5 = 12 + 0.5 = 12 + (1/2) = 12 & 1/2

The answer is choice F) 12 & 1/2 square yards.
