Since the linear dimension of the mitochondria is 10^-2 times that of the cell, the volume as a proportion of cell volume will be (10^-2)^3 = 10^-6. In order to make up 0.134 of the cell volume, there must be
(1.34×10^-1)/(10^-6) = 1.34×10^5
mitochondria in the cell.
There are about 134,000 mitochondria.
Answer:
Step-by-step explanation:
so your answer is No solution
8/(2x -2) = 14/(3x)
Cross multiply
24x = 28x - 28
Simplify. Isolate the x
24x (-28x) = 28x (-28x) - 28
24x - 28x = -28
-4x = -28
-4x/-4 = -28/-4
x = 6
-----------------------------------------------------------------------------------------------------------------
(x-10)/5 = 39/15
Cross multiply
15(x - 10) = 39(5)
Simplify
15x - 150 = 195
Isolate the x
15x - 150 (+150) = 195 (+150)
15x = 345
15x/15 = 345/15
x = 23
-----------------------------------------------------------------------------------------------------------------
(x + 4)/6 = (2x + 4)/9
Multiply 6 to both sides & 9 to both sides
9(x + 4) = 6(2x + 4)
Distribute 9 to x and 4, and 6 to 2x and 4
9x + 36 = 12x + 24
Isolate the x.
9x (-12x) + 36 (-36) = 12x (-12x) + 24 (-36)
9x - 12x = 24 - 36
-3x = -12
Isolate the x. divide -3 from both sides
-3x/-3 = -12/-3
x = -12/-3
x = 4

hope this helps
<span>1. Martina is given to be 14 years older than Joey who is x years old. Hence, the age of Martina can be expressed as,
x + 14
2. If Joey's current age is x then in 5 years he will become x+5 years old.
3. Martina's age will be her current age added with 5 making it, x+14+5 or x + 19.
4. The equation that would best represent the given scenario in this item is:
x + 19 = 3(x + 5)
5. From the given above, the value of x is equal to 2. This is Joey's current age.
6. The current age of Martina is x + 14 which is equal to 16.</span>
Answer:
B
Step-by-step explanation:
The formula to determine slope is .
Knowing this you can fill in the formula with the numbers:
2 - 4 is -2, so the numerator is -2.
-8 + 9 = 1, so your denominator is 1.
Therefore, your fraction is , or simply -2.
