Answer 1
Answer:

Answer:

Step-by-step explanation:

44√(40) + 7 √(160) = 4√(2*2*2*5)  + 7√(4*4*5*2)\n  = 4*2√(10)  + 7*4√(10)\n = 8√(10) + 28√(10) \n

= (8 + 28)√10

= 36√10

Answer 2
Answer:

Answer:

36√(10)

Step-by-step explanation:

Using the rule of radicals

√(a) × √(b)√(ab)

Simplifying the radicals in the expression

√(40)

= √(4(10))

= √(4) × √(10) = 2√(10)

√(160)

= √(16(10))

= √(16) × √(10) = 4√(10)

Thus

4√(40) + 7√(160)

= 4 × 2√(10) + 7 × 4√(10)

= 8√(10) + 28√(10)

= 36√(10)

Similar situation as you have before, let's starts from the easiest one which is D

2y = x

solve for y and you have y =x/2 which will show you on graph straight line

3/4y = 6x 

multiply by 4/3
y = [(6*4)/3]x
y=(24/3)x
y=8x

also straight line :)

y=2/5x-2/5 is same as y=0.4x-0.4 also will result as straight line graph :)

A migrating bird flies 420 miles in 12 hours . How many miles does it fly in 7 hours

Answers

first find miles per hour then multiply by 7
so 420/12=35
35 times7=245 mph
420 divided by 12 = 35 hours flown by the bird in 1 hour.
35 x 7(hours) = 245 miles flown in 7 hours

A flea weighs 8 decigrams, and an ant weighs 3 milligrams. How much more does a flea weigh than an ant?

Answers

In this question weight of a flea and an ant is given, but their units are different. So comparing and finding out the weight of flea and ant would be difficult. First thing that needs to be done is to bring the units of both the flea and the ant under same unit.
Weight of flea = 8 decigrams
Weight of ant = 3 milligrams.
Now let us convert the weight of the flea from decigrams to milligrams.
We already know that
1 decigram = 100 milligram
Then
8 decigrams = 100 * 8 milligrams
                     = 800 milligrams
Then
The weight by which the flea is greater than the ant = (800 - 3) milligrams
                                                                                   = 797 milligrams.
So the flea weighs 797 milligrams more than the ant.

Answer:

797 milligrams

Can u tell me how to solve this promblem 4/7 plus 3/7

Answers

The answer to your question is:  Yes, I can.
=================================
Although you haven't asked me to actually show you how, I'm already here
so I might as well just go on through it.


Before we tackle that math problem, I want to discuss a couple of other
different ones, and I want you to solve both of them.

Problem #1:     4 (cows) + 3 (cows)
Can you solve it ?
Did you say " 7 (cows) " ?
Nice work.

Problem #2:     4 (blue bicycles) + 3 ( blue bicycles)
This one is a little harder.
Can you solve it on your own ?
What's that ?  Did you say " 7 (blue bicycles) " ?
Excellent !

I think you're ready for the original problem now:

       4 (sevenths) + 3 (sevenths) = ?

I hope you said " 7 (sevenths) " .
You did ?  Terriffic !
That's the correct solution . . . . . ⁷/₇.

Teachers usually want to see fractions simplified.  That doesn't
change the answer, it's just a neater way to write it.

Any fraction that has the same number on top and bottom is always the same as ' 1 '.

⁷/₇ = 1 , so if you see the answer to this one in a book, it'll say ' 1 '.


It's pretty simple..
All you do is think about the numerator (the top number)
And the denominator (the bottom number)

If the denominators are the same number (which they are) then you keep that the same

And the numerators must be added together

In this case it would be 4+3 = 7

And the denominator stays the same
So your answer will be 7/7



If you want to get even higher with your answer, you can mention how 7/7 is also a WHOLE number
