Answer:
A) 9.56x10^38 ergs
B) 7.4x10^-3 mm
Step-by-step explanation:
A) 9.56x10^38 ergs B) 7.4x10^-3 mm A). For the sun, just multiply the power by time, so 3.9x10^33 erg/sec * 2.45x10^5 sec = 9.56x10^38 B) Of the two values 7.4x10^-3 and 7.4x10^3, the value 7.4x10^-3 is far more reasonable as a measurement for blood cell. Reason becomes quite evident if you take the 7.4x10^3 value and convert to a non-scientific notation value. Since the exponent is positive, shift the decimal point to the right. So 7.4x10^3 mm = 7400 mm, or in easier to understand terms, over 7 meters. That is way too large for a blood cell when you consider that you need a microscope to see one. Now the 7.4x10^-3 mm value converts to 0.0074 mm which is quite small and would a reasonable size for a blood cell.

Answer:
The markup percentage is 61.2
Step-by-step explanation:
Given as :
The cost price of each ornaments = $23
The sell price of each ornament = $37.08
Let The markup percentage = x
<u>Now, According to question</u>
Markup percentage = 
× 100
Or, x% = 
Or, x% = 
Or, x% = 0.612
∴ x = 0.612 × 100
I.e x = 61.2
So, The The markup percentage = x = 61.2
Hence, The markup percentage is 61.2 Answer
Problem 1
1/2 = 2/4
The mixed number 4 & 1/2 is the same as 4 & 2/4
Then convert that mixed number to an improper fraction using the formula below
a & b/c = (a*c+b)/c
4 & 2/4 = (4*4+2)/4
4 & 2/4 = 18/4
We could reduce this, but I'll keep it unreduced so that we keep the denominator of 4.
Now think of 3/4 as "3 fourths" and 18/4 as "18 fourths".
We could easily replace "fourths" with "unit" to say 3 units and 18 units respectively.
The problem can be rephrased into this question: "how many groups of 3 units are in 18 units?"
At this point, it's probably clear that there are 6 groupings since 18/3 = 6.
It might help to set up a drawing where there are 6 circles, and inside each circle would be 3 dots. So there are 3*6 = 18 dots total.
<h3>Answer: 6</h3>
===========================================================
Problem 2
3/4 = 9/12
2/3 = 8/12
2 2/3 = 2 8/12
2 & 8/12 = (2*12+8)/12 ... using the formula from earlier
2 & 8/12 = 32/12
Think of "twelfths" as a unit
So asking "how many groups of 9/12 are in 32/12" is the same as asking "how many groups of 9 units are in 32 units".
Divide the two numbers to find out
32/9 = (27+5)/9
32/9 = 27/9 + 5/9
32/9 = 3 + 5/9
32/9 = 3 & 5/9
Notice that if you were to convert the mixed number 3 & 5/9 to an improper fraction (using that formula mentioned), then you should get 32/9 back again.
<h3>Answer: 3 & 5/9</h3>
Answer:
No solution
Step-by-step explanation:
we know that
The <u>Triangle Inequality Theorem</u> states that the sum of any 2 sides of a triangle must be greater than the measure of the third side
so
In this problem
-----> is not true
therefore
You can't build a triangle with those dimensions
