Include a Claim, Evidence, Explanation, and Conclusion for full credit.

Cells were obtained from a patient with a viral infection. The DNA extracted from these cells consisted of two forms: double-stranded human DNA and single-stranded viral DNA. The base composition of these two forms of DNA are shown in the image.

Construct an argument based on evidence to determine which form was the viral DNA and which form was the human DNA.

Answer:

21°

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

subtract the sum of the 2 given angles from 180 for the other angle

other angle = 180° - (90 + 69)° = 180° - 159° = 21°

Answer:

C is the correct answer

Answer:

A

Step-by-step explanation:

because for each 6 you have 2

We can represent the number of potential outcomes by 2 to the power 6.

'In mathematics, permutation relates to the act of arranging all the members of a set into some sequence or order.

The combination is a way of selecting items from a collection, such that the order of selection does not matter.'

'The power of a number says how many times to use the number in a multiplication. Powers are also called exponents or indices.'

According to the given problem,

We can assume, for two choices, we have one decision.

This can be represented as [tex]2^{1}[/tex].

Since, we have six decisions,

Representation of the potential outcomes ⇒[tex]2^{1}+2^{1} +2^{1} +2^{1} +2^{1} +2^{1}[/tex]

                                                                       =  [tex]2^{6}[/tex]

                                                                       = [tex]64[/tex]

Hence, the representation of the number of potential outcome is 2 to the power 6.

Step-by-step explanation:

It's decreasing by 3 each time, so the next number in the sequence would be 6 - 3, which is 3.

Answer:

3

Step-by-step explanation:

because each number is decreasing by 3 so the next one would be 3

Answer:

12.2

Step-by-step explanation:

Let C be the last angle c + 55° + 35° = 180° (sum of angles in a triangle)

C + 90° = 180°

C = 180° - 90°

C = 90°

Let c be the last side

Using the sine rule a/sinA = b/sinB = c/sinC

Using any of the other two sides,

10/sin55° = c/sin90°

c = 10/sin55° × sin90°

c = 10/0.8192 × 1

c = 12.21

c ≅ 12.2

Answer:

Step-by-step explanation:

Answer:

Consider all the info you are given:

The monthly allowance is 2 GB...this is basically how much data is included in the the plan so that the monthly pymt is the same every month. When the GBs used goes pass 2GB...there is a cost to that.

You're given C(x) = 30x + 50, the monthly cost of the plan

'x' is the GB of data used OVER the allowance (2GB.)

They put over in italics to give you a hint to the solution.

(a) C(0.7) is the cost when the data used goes over 2GB by 0.7 GB. C(0.7) = 30(0.7) + 5 = 26

The college student would pay $26 when they use an extra 0.7GBs (pass the allowance.)

(b) This part to the problem wants you to figure out how much the overage, pass the 2GBs, the college student can go and only end up paying $50 (the set budget)

So you the solve for x by setting C(x) = 50

30x + 5 = 50

30x = 50 - 5 = 45

x = 45/30

x = 1.5

Remember x is the overage (the GBs over the allowances), so to stay at budget, the college student can use 3.5 GBs of data (2GBs + 1.5 GBs) only pay $50 that month.

Answer:

P = 0.5c - 75

Step-by-step explanation:

Profit is = selling price. - cost price

Cost price is the amount the supplies were bought = $75

The cost of c cups at $0.5 per cup will be

0.5 * c = $0.5c

The profit here is thus;

P = 0.5c - 75

Answer:

n= -3.5

Step-by-step explanation:

n/7 - 12 = 5n +5

+12            +12

n/7 = 5n+17

*7      *7

n = (5n+17)*7

n = 35n + 119

-35n    -35n

-34n = 119

/-34     /-34

n = -3.5

It is a right triangle. The distance is the hypotenuse of the triangle.

Use the Pythagorean theorem:

Distance = sqrt(3^2 + 2^2)

Distance = sqrt( 9 + 4)

Distance = sqrt(13) (exact distance)

As a decimal sqrt(13) = 3.60555

Answer:

x < - 8

Step-by-step explanation:

Given

3(x + 1) + 11 < - 2(x + 13) ← distribute parenthesis on both sides

3x + 3 + 11 < - 2x - 26

3x + 14 < - 2x - 26 ( add 2x to both sides )

5x + 14 < - 26 ( subtract 14 from both sides )

5x < - 40 ( divide both sides by 5 )

x < - 8

Answer:

x<-8

Step-by-step explanation:

3x+14<-2x-26(combine and distribute)

3x+14-14<-2x-26-14(subtract 14 from both sides)

3x<-2x-40(add 2x to both sides)

5x<-40(divide both sides by 5

x<-8(this is your final answer)
