Step-by-step explanation:
In genetics, a reciprocal cross is a breeding experiment designed to test the role of parental sex on a given inheritance pattern.[1] All parent organisms must be true breeding to properly carry out such an experiment. In one cross, a male expressing the trait of interest will be crossed with a female not expressing the trait. In the other, a female expressing the trait of interest will be crossed with a male not expressing the trait. It is the cross that could be made either way or independent of the sex of the parents. For example, suppose a biologist wished to identify whether a hypothetical allele Z, a variant of some gene A, is on the male or female sex chromosome. She might first cross a Z-trait female with an A-trait male and observe the offspring. Next, she would cross an A-trait female with a Z-trait male and observe the offspring. Via principles of dominant and recessive alleles, she could then (perhaps after cross-breeding the offspring as well) make an inference as to which sex chromosome contains the gene Z, if either in fact did.
All these rooms are rectangles so to find the area of the rooms multiply length by width.
Living Room: 5x4 = 20 m²
Kitchen: 4x3 = 12 m²
Dining Room: 4x2 = 8 m²
6(x^2-1)(6x-1/6(x+1))
On factoring (x^2-1)=(x+1)(x-1)
= 6(x-1)(x+1)(6x-1/6(x+1))
Cancelling (x+1) from numerator and denominator we get,
= 6(x-1)(6x-1)/6
Cancelling 6 we get,
= (x-1)(6x-1)
Find the lowest common multiple=
8= 8,16,24,32,40,48
6=6,12,18,24,30,36
the lowest common multiple is 24 so then
4/8>>>>?/24 you times 8 by 3 to get 24 so you times 4 by 3 which equals 12 so it would be 12/24 (or a half)
then
4/6>>>>?/24 you times 6 by 4 to get 24 so you times 4 by 4 which equals 16 so it would be 16/24
12/24(4/8) is greater or less than 16/24(4/6)
it is less than. :)
Answer:
Julie can buy 4 plants
Step-by-step explanation:
A plant costs £6.80 and Julie has £30.
In order to find out how many plants she can buy with £30, we need to see how much times £6.80 can go into £30. In other words, we need to divide £30 by £6.80 so we get the number times it can go into £30. That will be the number of plants.
£30 ÷ £6.80 = 4.41176470588
Julie can't get 0.41176470588 of a plant so we have to round it to 4. She can buy 4 plants.
She has a bit of money left over (you can tell by the decimal number), but that isn't enough to buy another plant. So she buys 4 and has £2.80 left.
£6.80 x 4 = £27.20
