inverse operation for 20n=300

Answer:

A) Nucleus

Step-by-step explanation:

By housing the cell's genome, the nucleus serves both as the repository of genetic information and as the cell's control center. DNA replication, transcription, and RNA processing all take place within the nucleus, with only the final stage of gene expression (translation) localized to the cytoplasm.

Step-by-step explanation:

1. 3x + 2y - 2x + y + 12 is equivalent to x + 3y + 12

2. 4y + 3y + 3x - 6y - 10 - 2 is equivalent to 3x + y - 12

3. x + 3y + 2x - 3x + 7 + 5 is equivalent to 3y + 12

4. I do not know unfortunately

Answer:

See attached image

Step-by-step explanation:

To solve this, first simplify the compound expressions - the ones with multiple x, y terms and see which of the other expressions matches the simplified expression

I will tell you how to solve one of the more complex expressions; the technique is the same for the rest

Let's take the very last expression
4y + 3y + 3x - 6y -10 - 2

To simplify,

group like terms:

=(4y + 3y - 6y) + 3x +(-10 -2)

= y + 3x - 12

Rewriting with x before y gives
3x + y - 12

and there is a matching 3x + y - 12

4y + 3y + 3x - 6y -10 - 2   ⇔  3x + y - 12

Step-by-step explanation:

Sum their ages , 11 + 19 + 20 = 50

Divide £500 by 50 to find the value of one part of the ratio

£500 ÷ 50 = £10, thus

11 × £10 = £110 ← Pete's share

19 × £10 = £190 ← Fred's share

20 × £10 = £200 ← Sarah's share

Answer:

Pete's share: £110

Fred's share: £190

Sarah's share: £200

Step-by-step explanation:

Add their ages:

11 + 19 + 20 = 50

500 ÷ 50 = £10

Then you times their age with £10 to get how much they all get.

10 x 11 = £110

19 x 10 = £190

20 x 10 = £200

Step-by-step explanation:

To find the median of a set of data, arrange the data by value:

6, 7, 9, 12, 13

The number in the middle is the median.

Answer:

median is 9

Step-by-step explanation:

to find median u must arrange the data from ascending to descending order.

6 , 7 , 9 , 12 , 13

median = N + 1/2   (N means no of data)

= 5 + 1/2

= 6/2

= 3 th term

Answer:

see below

Step-by-step explanation:

If we are given the equation of a line in this format:

y=mx+b

then it is quite simple to find the gradient and y-intercept.

In the format:

y=mx+b

the m represents the gradient (slope) and b represents the y-interpcept.

1) y=2x+3

gradient= 2

y-intercept= 3

2) y=x-5

gradient=  1

y-intercept= -5

3) y=-2x-4

gradient= -2

y-intercept= -4

4) y=5-x

gradient= -1

y-intercept= 5

5) y=3x+8

gradient= 3

y-intercept= 8

6) y= 1/4x+3

gradient= 1/4

y-intercept= 3

Answer: 48 small shirts

108 medium shirts

84 Large shirts

Step-by-step explanation:

20% of 240 = 48

45% pf 240 = 108

45 + 20 = 65, 100 - 65 = 35

35% of 240 = 84

And 48 + 108 + 84 = 240

Step-by-step explanation:

1. set up a raito

2. triangle must be 180 so add 70 then subtract

3. since its complenatry it must be 90 degrees, subtract 53 from 90

Answer:

Big triangle= 4*1.5=6

Small Triangle= 7.5/1.5=5

Ratio=7.5/5 or 1.5

Step-by-step explanation:

\(\frac{7}{10.5}\)=\(\frac{x}{7.5}\)

cross multiply

10.5x=52.5

divide both sides by 10.5

x=5

7.5/5= ratio

The correct proportion to use to find the amount of orange juice, j, needed to add to 18 L of pineapple juice is:

2/8 = j/18

This proportion relates the ratio of orange juice to pineapple juice in the recipe (2:8) to the amount of orange juice needed to add to 18 L of pineapple juice. By cross-multiplying, we can solve for j as follows:

2/8 = j/18

218 = 8j

36 = 8*j

j = 36/8

j = 4.5

Therefore, you would need to add 4.5 L of orange juice to 18 L of pineapple juice to create the fruit juice recipe that calls for a ratio of 2 parts orange juice to 8 parts pineapple juice.

Answer:

Step-by-step explanation
2 over 8 equals j over 18

This proportion represents the ratio of orange juice to pineapple juice in the recipe. By setting up the proportion, we can solve for the value of 'j,' which represents the amount of orange juice needed.

So, the correct proportion is:

Slope of the new road parallel to Brodie Lane will be Option (B). 0

    Given in the question,

Since, all the lines parallel to x-axis have the slope = 0

Therefore, new road parallel to Brodie lane will be parallel to x-axis and slope of the new road will be 0.

    Hence, Option B will be the correct option.

the ratio of the scale drawing is

1 inch on the drawing represents 180 feet in real life.

To determine the ratio of the scale drawing, we need to first find the length of the building on the scale drawing. We know that the actual length of the building is 60 feet, and the length of the building on the scale drawing is 4 inches. We can set up a proportion to find the length of the building on the scale drawing:

Actual length / Length on scale drawing = Scale factor

We can plug in the values we know:

60 feet / Length on scale drawing in inches = Scale factor

To solve for the length on the scale drawing in inches, we can cross-multiply:

60 feet * 1 inch / Scale factor = Length on scale drawing in inches

Simplifying:

Length on scale drawing in inches = 60 feet * 12 inches / Scale factor

We know that the length on the scale drawing is 4 inches, so we can plug that into the equation:

4 inches = 60 feet * 12 inches / Scale factor

Solving for the scale factor:

Scale factor = 60 feet * 12 inches / 4 inches

Scale factor = 180

The following conclusions can be drawn from the circle graph:

Cable Car is the preferred transportation for 75 residents. (27% of 300 = 81 residents)

Together, Streetcar and Bus are the preferred transportation for 25% of residents. (15% + 10% = 25% of 300 = 75 residents)

The other two statements are incorrect:

Bicycle is the preferred transportation for 8% of residents, not 30. (8% of 300 = 24 residents)

Together, Bus and Bicycle are the preferred transportation for 18% of residents, not 54. (10% + 8% = 18% of 300 = 54 residents)

Answer:

A

Step-by-step explanation:

We can solve for H by isolating it on one side of the equation, as follows:

J/H - I/H = G

Taking H as the common denominator:

(J - I)/H = G

Multiplying both sides by H:

J - I = GH

Adding I to both sides:

J = GH + I

Dividing both sides by G:

H = (J - I)/G

So the answer is

(A)

H = (J - I)/G.

Answer:   A

Step-by-step explanation:

\(\frac{J}{H} = G + \frac{I}{H}\)                >Since you are solving for H bring I/H to the other side

                                   by subtracting I/H from both sides

\(\frac{J}{H}- \frac{I}{H} = G\)               >There is a common denominator so you can

                                   combine the fractions

\(\frac{J-I}{H} = G\)                   >Multiply both sides by H or cross multiply whichever

                                  way your mind things about how to get H on top

\(J-I = G(H)\)           >Divide both sides by G

\(\frac{J-I}{G} = H\)                   >Answer is A

Answer:

First, we know that:

1 1/3 = 4/3

10 2/3 = 32/3

15 minutes = 0.25 hours

Let's imagine that x (hours) is the time it takes Lee to type 32/3 pages.

From the information, we can tell that:

Lee can type:

4/3 pages in 0.25 hours

32/4 pages in x hours

So x should be:

x = (32/4 . 0.25)/4/3 = 2 (hours)

So it takes Lee 2 hours ro type 10 2/3 pages
