Answer:

I think it would be 17 because if you subtract 47 by 13 it will give you 34 and if you divide it by 2 it will give you 17.

Answer:

The length of longer piece is 30 inches.

Step-by-step explanation:

Firstly, you have to make an expression in terms of x where x represents the length of the shorter piece . Given that the total length is 47 inches and the longer piece is 13 inches longer that the shorter one. Using this information, you can form an expression :

Shorter piece =>

x inches

Longer piece =>

(13 + x) inches

Total length =>

x + 13 + x = 47

2x + 13 = 47

now, you can solve to find the value of x by substracting 13 to both sides then divide it by 2:

2x + 13 - 13 = 47 - 13

2x = 34

2x ÷ 2 = 34 ÷ 2

x = 17 inches

We have found the shorter piece. The question wants to find the longer piece so you have to substitute the value of x into the expression of longer piece :

Let x be 17 inches,

13 + x = 13 + 17

= 30 inches

Jocelyn sells necklaces for $8 each. It costs her $20 for

Charra [1.4K]

We see that the slope intercept is y = 8x - 20. So if we substitute x with 2, because x represents the amount of necklaces sold and we are analyzing her net profit after selling 2 necklaces, that gives us y = 8(2) - 20. Which simplifies to y = -4. So by the time Jocelyn sells 2 necklaces, her net profit will be at -4.

"Suppose that allele D produces long toes and allele d produces normal toes. A heterozygous male with the Dd genotype mates with

VARVARA [1.3K]

Answer:

30%

Step-by-step explanation:

The crossing of a male with genotype Dd with a female with genotype dd, yields the following possible outcomes:

Dd, dD, dd, dd.

Therefore, there is a 2 in 4, (50%) chance that their offspring will have the dominant allele. Since its penetrance is 60%, the dominant trait will only manifest itself in 60% of heterozygous individuals. Therefore, the probability that their offspring will have long toes is:

$P = 0.50*0.60\\P=30\%$
