9+10=19 not 21
and in roman numerals IX+X equals IXX because if you put the "I" in front of the "X" it means that the number is 1 less than the value X ("X" in roman numerals equals 10 and "I" equals 1). Also if you put the "I" after the "X" it means that the value of that roman numeral is 1 more then "X".

Not if you keep the ' l ' before the ' XX ' where it belongs. If it's before, then it means take the ' l ' away from them, and you get 19 just as you should. Now I understand this crazy question that keeps coming around.

Find the area for this pls
Anit [1.1K]

Answer:

3,36 in^2

Step-by-step explanation:

The geometric shape shown in image is called a trapezoid

to calculate the area of a trapezoid we use the following formula:

1/2*(a+b)*h (a and b are bases, h: height)

bases are 1.3 and 3.5 and height is 1.4

1/2(1.3 + 3.5)*(1.4) = 3,36 the area is stated in square units so the answer is

3,36 in^2

Three-fourths of a research team worked in a lab while one-fourth of the team worked near a pond. Of the researchers who worked
Lisa [10]

Answer:

3.5%

Step-by-step explanation:

In this case, the final probability would be the product of the two probabilities that the plating shows us:

First probability would be:

We are told that three quarters of the equipment (3/4) in the laboratory and the other quarter (1/4) near the pond, we are interested in the latter, that is, the probability is 1/4 = 0.25

Second probability:

We are told that 14% collected insects, therefore it would be 0.14

The final product is the question they ask us:

0.25 * 0.14 = 0.035

Which means that the joint probability is 3.5%

Solve for x: log(3) + 2 log(x) = log(27)
Rom4ik [11]

Answer:

The solution is x = 3

Step-by-step explanation:

Hi there!

First, let´s write the equation:

log(3) + 2 log(x) = log(27)

Substract log(3) from both sides of the equation

2 log(x) = log(27) - log(3)

Apply logarithm property: log(a) -log(b) = log(a/b)

2 log(x) = log(27/3)

2 log(x) = log(9)

Apply logarithm property: log(xᵃ) = a log(x)

log(x²) = log(9)

Apply logarithm equality rule: if log(a) = log(b) then a = b

x² = 9

Apply square root to both sides of the equation

x = 3

The solution is x = 3

Have a nice day!
