Divide 450 grams into ratio 7:2

1 answer:

6 0

Let us assume the common ratio = x
Then from the given question we can write
7x + 2x = 450
9x = 450
x = 450/9
   = 50
Then the quantity 450 grams can be divided in the ratio of 7 : 2 by = 7x:2x
      = (7 * 50) : (2 * 50)
      = 350:100
I hope this is the answer you were looking for and the procedure for finding the answer is also absolutely clear to you.

The equation 22 = 2y + x represents the perimeter of a flower garden with

iren [92.7K]

Answer:

$y = \frac{22-x}{2}$

For width = 2 ft, the length of the flower bed = 10 ft.

For width = 3 ft, the length of the flower bed = 9.5 ft.

For width = 4 ft, the length of the flower bed = 9 ft.

Step-by-step explanation:

Here, the Perimeter of the flower garden is given as

22 = 2 y + x

: where, y : Length of the garden

and x : Width of the garden .

Now, solving for y in the above expression,we get

22 = 2 y + x ⇒ 22 - x = 2 y

or, $y = \frac{22-x}{2}$

Now, when the width (x) = 2 feet

Length of the flower bed $y = \frac{22-x}{2} = \frac{22-2}{2} = \frac{20}{2} = 10$

or, x = 10 ft

⇒For, the width = 2 ft, the length of the flower bed = 10 ft.

when the width (x) = 3 feet

Length of the flower bed $y = \frac{22-x}{2} = \frac{22-3}{2} = \frac{19}{2} = 9.5$

or, x = 9.5 ft

⇒For, the width = 3 ft, the length of the flower bed = 9.5 ft.

when the width (x) = 4 feet

Length of the flower bed $y = \frac{22-x}{2} = \frac{22-4}{2} = \frac{18}{2} = 9$

or, x = 9 ft

⇒For, the width = 4 ft, the length of the flower bed = 9 ft.

INSERT TWO RATIONAL NUMBERS BETWEEN 2 AND 3. How to find them?

Kay [80]

There are an infinite number of them.
Here are a few:

2.1
2.2
2.3
2.3000000001
2.30000000000000006
2.5
2.00009
.
.
etc.

How to find them:

You probably never heard this before, but I'll bet
you'll remember it from now on:

ANY number that you can write down on paper completely, using digits
and a decimal point if you need it but no symbols, is a rational number.

If you can write it down completely without any 'comments', then it's rational.

Evaluate 38+16 * 12÷2-(30 * 2)

Dvinal [7]

Answer

The answer is 8040

Step-by-step explanation:

It might be wrong, but here take it this way with Pemdas.

P= Parenthesis (30*2) and what's in there is multiplication correct? So, 30 times 2 is 60. Then, E is exponents. There's none there. So we skip to multiplication. 16 times 12 is what? 192. Next is division. So 192 divided by 2. That's 96. So, Then it'd be 38+96(60.) 38+96= 134. 134(60) That being said. That would equal = 8040 using Multiplication, 194 using addition. 74 using subtraction. And 2.2_ using division.
