PLZ HELP!!

39+(-20.4)

When you answer can you plz show how you got the answer plz!!

Answers

Answer 1

Answer:

i think is 18.6 I not sure

Answer 2
It will be +18.6
Because (-20.4) is a negative number
Imagine a number line you would need 20.4 to get back to 0 since you will start at negative 20.4
39-20.4 is 18.6
So you have 18.6 left which will be on the positive side so that’s the answer

A plant takes up water from the soil through its roots. While most of the water taken up by the plant is lost by the leaves of the plant, some of the water is used.

How is this water used by the plant?


It is used to produce food.

It is used to attract insects.

It is used in the process of respiration.

It is used in the process of moving the plant toward the light.

Answers

C.

It is used in the process of respiration.

Hope this help! DON'T FORGET TO MARK ME BRAINLIEST

Answer:

D

Step-by-step explanation:

I looked this up so I'm pretty sure this is correct however it still could be wrong. From my newfound understanding, the water is absorbed and goes up the xylem where most of it goes to the plant and only a small bit is left for the plant to grow

plants need sunlight to make their own food as we've been taught for years. many plants will actually grow toward sunlight. If they're saving that water to grow, they might as well grow toward the sunlight.

that's my explanation and my train of thought. I hope this helped!

Zachary traveled from city A to city B. He left city A at 7:30 a.m. and reached city B at 12 noon. Find his average speed if city B is 180 mi away from city A.


Please include the units after the answer!

Answers

Answer:

40 mph

Step-by-step explanation:

s = d/t

a to b's distance = 180 miles

7:30 - 12pm = 4.5 hours (time)

speed = 180 ÷ 4.5

speed = 40

40mph because it is 180 miles away and it took him 4.5 hours u divide 180 by 4,5
