Which unit rates would be appropriate for describing the rate of growth of a tree?

1 answer:

5 0

<span>I got two answers is that okay? The question said to select each correct answer implying that there could be more than one.

inches per year - this could make sense as well because you could easily measure the number of inches a tree grew in a year.

millimeters per week- I suppose this makes sense how fast the specific tree grew. So, if you are alllowed to pick two answers I think you could make a strong case to your teacher that this unit has the potential to be logical rate unit for tree growth.

milliliters per minute - NO. I think that this would be an illogical rate unit to use for trees because their growth is so slow that it wouldn't change by a measurable amount in just a minuet.

miles per hour - NO. Trees do not grow fast enough for this to be a logical unit rate to use. </span>

After 4,000 gallons of water were added to a large water tank that was already filled to 3/4 of its capacity, the tank was then

dangina [55]

Answer: The correct option is

(E) 80,000.

Step-by-step explanation: Given that after adding 4,000 gallons of water to a large tank that was already filled to $\dfrac{3}{4}$ of its capacity, the tank was then at $\drac{4}{5}$ of its capacity.

We are to find the number of gallons of water that the tank hold when filled to capacity.

Let the tank can hold x gallons of water when filled to capacity.

Then, according to the given information, we have

$\dfrac{3}{4}x+4000=\dfrac{4}{5}x\\\\\\\Rightarrow \dfrac{4}{5}x-\dfrac{3}{4}x=4000\\\\\\\Rightarrow \dfrac{16-15}{20}x=4000\\\\\Rightarrow x=4000\times20\\\\\Rightarrow x=80000.$

Thus, the required capacity of the tank is 80,000 gallons of water.

Option (E) is CORRECT.

Here is a list of numbers: 13, 15, -6, 8, -16, 2, -12 ,3 ,-18 ,-18 state the median.

DiKsa [7]

The median of list of numbers is-2.

Given the list of numbers is 13,15,6,8,-16,2,-12,3,-18,-18.

The median is the median of a sorted list of numbers. To find the median of a sequence of numbers, the numbers must be sorted in order from lowest to highest or highest to lowest.

Firstly, we will arrange the number from ascending to descending, we get

-18,-18,-16,-12,-6,2,3,8,13,15.

Now, we will find the middle term of the sequence, we get

The middle terms are -6 and 2.

Further, we will find the median of it.

n=(-6+2)/2

n=-4/2

n=-2

Hence, the median of the list of numbers 13, 15, -6, 8, -16, 2, -12 ,3 ,-18 ,-18 is -2.

HELP! What is the measure of angle ABE? WILL GIVE BRAINLIEST!

Mazyrski [523]

Answer:

Step-by-step explanation:

Bisection is the division of a line or an angle into two equal halves. It means that a bisector is a line that divides an angle or another line into two equal halves. Therefore,

Line BE divides angle ABC into two equal halves. This means that

Angle ABC/2 = angle ABE = angle EBC

Therefore,.

2x + 20 = 4x - 6

4x - 2x = 20 + 6

2x = 26

x = 26/2 = 13

Therefore,

Angle ABE = 2 × 13 + 20

= 46 degrees
