Answer: The answer is in the attached figure.

Step-by-step explanation: We are given to draw a net for a rectangular prism of length 8 units, width 2 units and height 3 units.

What is a rectangular prism? It is a a solid three-dimensional object consisting of six faces, where each of the face is a rectangle. The same cross-section along a length of a rectangular prism makes it a prism. We also call it as a cuboid.

As given in the question, a rectangular prism ABCDEFGH is drawn in the attached figure, where length is 8 units, width is 2 units and height is 3 units.

Sholpan [36]

Answer and explanation :

We have given that the expression $\frac{2^{n+1}}{3^n}=2\times (\frac{2}{3})^n$

We have to prove L.H.S = R.H.S

Lets take L.H.S

$\frac{2^{n+1}}{3^n}$

It can be written as $\frac{2^{n+1}}{3^n}=\frac{2^n\times 2^1}{3^n}$ ( As in multiplication exponent are added )

So $\frac{2^n\times 2^1}{3^n}=(\frac{2}{3})^n\times 2$ = R.H.S

Hence proved

Someone please help and thx

Answer:

60 + 70n ≤ 200

Step-by-step explanation:

Since the $200 is a maximum, only inequalities with "≤ 200" make any sense in this context.

Since the unit rate for training sessins is $70, only expressions containing 70n make any sense in this context.

The only inequaity that makes any sense in this context is ...

60 + 70n ≤ 200

What is 7 40/81 rounded to the nearest whole number

polet [3.4K]

If you divide, you get 9.135......
Therefore, you look at the digit after the decimal point that is 1 so it will be 9 since it's less than 5
So the answer is 9

Discuss his principles of inheritance by answering the following questions. Two plants are being crossed, each heterozygous for

disa [49]

Answer:

Q1 - What is the possibility that the offspring will have white flowers? Express your answer as a ratio.

A: White flowers only appear if the offspring is homozygous for b because this phenotype is recessive, so they have to present bb phenotype. If both parents are heterozygous (Bb), each one gives one gene at a time per individual after crossing, so 1/4 would be BB, 2/4 would be Bb and 1/4 would be bb.

Q2 - If one parent is also heterozygous for smooth peas, does this mean that all of the offspring with blue flowers will also have smooth peas? Explain your answer without using a Punnett square.

A: No, it doesn't mean that all blue flowers will present smooth peas because those genes are expressed in different loci, so they segregate independently. There might be some blue flowers with smooth peas, but that is not mandatory for all of them.

Q3 - Suppose both parents are also heterozygous for smooth peas (S), with wrinkled peas (s) as the recessive trait. Use a Punnett square to predict the possibility that the offspring will be homozygous for both flower color and pea texture. Make sure to include a Punnett square and express your prediction as a ratio.

A: Parental genotypes are BbSs x BbSs. Given that the genes segregate independently, we will have the Punnett diagram as follows:

BS / Bs / bS / bs

BS BBSS / BBSs / BbSS / BbSs

Bs BBSs / BBss / BbSs / Bbss

bS BbSS / BbSs / bbSS / bbSs

bs BbSs / Bbss / bbSs / bbss

Homozygous genotypes are the ones that both genes are the same when expressed, either BB,bb,SS or ss. The probability the offspring is homozygous for both flower color and pea texture is 4/16, or 1/4.
