3 lumps equals 1 clump and 10 clumps equals 1 pile, how many piles are 96 lumps

Lera25 [3.4K]

Answer:

3.2 piles

Explanation:

step 1

Find out the number of lumps in 10 clumps

we know that

3 lumps equals 1 clump

by proportion

Let

x ----> the number of lumps

$\frac{3}{1} \frac{lumps}{clump}=\frac{x}{10} \frac{lumps}{clumps}\\\\x=10(3)\\\\x=30\ lumps$

step 2

Find out how many piles are 96 lumps

we know that

10 clumps equals 1 pile

10 clumps equals 30 lumps

1 pile equals 30 lumps

using proportion

Let

x -----> the number of piles

$\frac{1}{30}\frac{pile}{lumps}=\frac{x}{96}\frac{piles}{lumps} \\\\x=96/30\\\\x=3.2\ piles$

Color-blindness is an x-linked recessive condition. a man with normal vision is married to a woman with normal vision, but whose

pentagon [3]

Since color blindness is a sex-linked recessive genetic disorder, it is carried by a X chromosome. Males (XY) are affected if they get the affected X from their mother, since males only have one X, and it is therefore always expressed. Females (XX), however, get one X from their mother and the other from their father. So both parents have to pass a color blind X to be affected (both alleles, by the definition of recessive).
Even though the mother is not affected, she's carrying it because her father was color blind. And the father is not affected. However, in Turner's Syndrome, one X is destroyed after fertilization, so the other X is the daughter's primary (only remaining) X. Note: Turners only affects females. Therefore, this is a rare situation in which a daughter gets affected by an X-linked recessive condition.

Answer:

Males have 1 or sometimes even 2 reproductive organs that direct sperm to a female. The sperm fertilizes eggs, sometimes even in the hundreds or thousands. That is how all reptiles reproduce.
