A cylindrical tin full of engine oil has a diameter of 12cm and a height of 14cm.The oil is poured into a rectangular tin 16cm l

galben [10]

Answer:

Depth = 9 cm

Explanation:

First, calculate the volume of the cylindrical tin.

Mathematically, that would be the following:

$V = \pi * r^{2} * h$

Now, r = d/2 = 12/2 = 6 cm

h = 9 cm

Therefore, the volume will be:

V = 22/7 * 14 * 6^2 =1,584 cm^3

Now, to find the the depth of the tin, we have to realize that the content of the cylinder should fill in the tin to a particular height.

As we don't have the height of the tin so let's suppose it x, now it means that

l * b * h = 16 * 11 * x = 176x

Therefore, the depth would be:

176x = 1584

x = 1584 / 176 = <u>9 cm</u>

Suppose that allele D produces tiny ears and allele d produces normal ears. A heterozygous male with the Dd genotype mates with

kotegsom [21]

Answer:

The correct answer is 35 percent.

Explanation:

Allele D produced tiny ears, and allele d produces normal ones. If a heterozygous male with Dd mates with the homozygous female with dd, then generally, the expected offspring produced will be 50 percent with tiny ears, and 50 percent with normal ears.

However, in the given case, the penetrance is 70 percent. Thus, the probability of the offspring with tiny ears will be:

Penetrance = 70 %

Probability = 70 % of 50 % of 100

= 70/100 * 50/100 * 100

= 35 %

Hence, the probability of the offspring with tiny ears is 35%.
