The dragonfly is the fastest flying insect it can move at a speed of about 50 feet per second find the approximate time for a dragonfly to travel 400ft
Answers
Answer:
8 seconds
Step-by-step explanation:
400 divided by 50 is 8
Answer: 8 sec
Step-by-step explanation
50 = 1sec
50 + 50 = 100
50 + 50 + 50 + 50 = 200
You keep adding 50 until you reach 400
Every 50 you add is 1 sec so if you add eight 50’s it would be 400 and that would mean it takes him 8 seconds to travel 400ft

First you need to find the perimeter which the formula is P=2L+2w
P=24
SA = 2B + Ph
SA = 12 + 24
SA = 36

Answer:
-2/3
Step-by-step explanation:
To find the slope, you use rise over run. so 12 - 10 over 2 - 5. That is 2 over negative 3. so negative two thirds. I hope this helps and please mark me brainliest!

The required value of the expression 2w - 2 when w = 5 is 8.
Given that,
what is the value of the expression 2w-2 when 5=w is to be determined.
What is arithmetic?
In mathematics, it is defined as the number of operations performed according to the statements.
What is simplification?
The method in mathematics to work and interpret the functions or expressions to make the functions or expressions simple or more understandable is called simplifying and the process is called simplification.
Here,
The given expression is 2w - 2
W = 5
= 2 * 5 - 2
= 10 - 2
= 8
Thus, the required value of the expression 2w - 2 when w = 5 is 8.

w = 5
2(5) - 2
10 - 2 = 8
The value would be 8

Before I show you either of these, I'm going to define rational numbers and explain some things so that you can understand why we do what we do. Make sure to remember things like this because when you get to algebra (I'm in algebra), you need to know all of this stuff! :)
A rational number is any number that can be written in a over b form (a/b) or as a fraction. A rational number can be positive or negative because you can put positive and negative numbers into a fraction. Decimals can also be rational numbers because things such as .3 can be written as 3/10. So, depending on what number you have, there is always an opposite.
To find an opposite number, you have to basically find the absolute value (how far the number is from zero), double that number, and add it from the original number. Or, if you want to make it worlds easier, you can just make the number the opposite inverse. So, if it is -4, the opposite is 4. If the number is 7, then the opposite is -7. What is the sum between both of those examples? Zero.
Here is the formula: a+(-a)=0, (-a)+a=0
Here is some examples: (-5)+5=0, 8+(-8)=0
Thanks so much for the opportunity to answer your question. I hope this helped! :)
