Answer:

Option A is correct

20+10h

Step-by-step explanation:

As per the statement:

A plant is 20 inches tall.

It is also given that:

If the plant grows 2h inches each week for the next 4 weeks,

⇒(2h) \cdot 4 = 8h

and

h inches for each of the 2 weeks .

⇒(h) \cdot 2 = 2h

Then,  every 2 weeks after that, another 2h.

⇒ in 6 weeks, a total of 10h inches height of the plant grows

We have to find the expression shows the height of the plant in inches after 6 weeks.

Initially, a plant is 20 inches tall.

in 6 week,  a total of 10h inches height of the plant grows

⇒the height of the plant in inches after 6 weeks = 20 + 10h

Therefore, the expression shows the height of the plant in inches after 6 weeks is, 20+ 10h

A) 20+10h

You know that you have 20 inches to start with, then it will grow 2h four times, or 8h total. Then it will grow h 2 times, or 2h. You add the 20, 8h, and 2h, to get 20+10h.

Hope this helps!

One of the same side angles of two parallel lines is 20° smaller than the other one. Find all angles.
KiRa [710]
Hello.

First, draw a picture of two parallel lines and a transversal.
Find the two same side angles, either the same side interior or the same side exterior.
We do not know the measurement of the angle, so we'll label it x.
The second angle is 20° smaller than the other one so we'll label is x-20

Same side angles are supplementary. Meaning that they add up to 180°

Next, make an equation.
1st angle + 2nd angle = 180°
Now substitute the first and second angle to x and x-20
The substituted equation should now look like this.
x+x-20=180
solve it and you'll get...
x=100

But we're not done.

The angle labeled x is 100°
The other one is x-20
And since x=100, the second angle is 100-20=80°
Now use linear pairs, more same side angles, vertical angles, alternate angles, and linear pairs, to label the rest. Remember that each angle is either 100° or 80°.

Hope this helped!

2. Luanne read the same number of pages in
neonofarm [45]

Answer:

48 pages

Step-by-step explanation:

Total no of pages = 196 pages

No of pages read on last day = 52 pages

Subtract the amount she read on the fourth day from the total no of pages.

196 pages - 52 pages = 144 pages

No of pages on the first three days = 144 pages

No of pages read each day = 144/3 = 48 pages

The middle person in a row is the 16th, how many persons are in the row?
Reptile [31]

Answer:

There are 31 people in the row

Step-by-step explanation:

Let us say that the number of people in the row is = x

We can also assume that the people arranged in the row are counted from one end.

The median value can be got using the formula:

median (middle person) = (n +1 )/2

where n = number of people in the row

hence, we will have

16 = (n +1)/2

n = 32 -1 =31

Therefore, there are 31 persons in the row

Ugo [173]

Answer:

X=7.5

Step-by-step explanation:

Try that.

The scale factor is 2.25

So you do:6*2.25=13.5

Then you do:13.5-6= 7.5
