What is 0.0000000345 in scientific notation?

Answer:

Step-by-step explanation:

Part A : Since sides of triangle are ( 1.9x + 6.2y )cm

(2.5x + 8.3w)cm and (1.6w - 5.1y)cm.

Now perimeter of a triangle = sum of all sides length

Perimeter = (1.9x + 6.2y) + (2.5x + 8.3w) + (1.6w - 5.1y)

                = (1.9x + 2.5x) + (6.2y - 5.1y) + (8.3w + 1.6w)

[ collecting the like terms together ]

Perimeter = 4.4x + 1.1y + 9.9w

Part B : Now we factorize the term for perimeter given in part A.

Perimeter = 1.1 (4x + y + 9w)

So equivalent factor will be (1.1 (4x + y + 9w).

Answer:

see explanation

Step-by-step explanation:

A

The perimeter is the sum of the 3 sides, thus summing the 3 sides

1.9x + 6.2y + 2.5x + 8.3w + 1.6w - 5.1y ← combine like terms

= 4.4x + 1.1y + 9.9w ← expression for perimeter

B

Factor out 1.1 from each term, thus

4.4x + 1.1y + 9.9w

= 1.1(4x + y + 9w) ← perimeter in factored form

The equation for the given phrase is 6x-9=-15 and the solution for the obtained equation is -1.

The given phrase is "nine less than six times a number is -15."

Let the unknown number be x.

Here, six times a number = 6x

The product is less than 9, that is

6x-9

Nine less than six times a number is -15, so the equation is

6x-9=-15

Now, the solution is

6x=-15+9

6x=-6

x=-6/6

x=-1

Therefore, the equation for the given phrase is 6x-9=-15 and the solution for the obtained equation is -1.

Hello!

6 - 9 × y = -15

When "less than" is used you switch the number before it the number after it. While it seems like it would be 9 -6, its actually 6-9

6 - 9 is -3, you can multiply 3 by 5, to get 15. So your answer would be 5

The unsimplified ratio of raisins to mixed nuts in the trail mix is:

4/15 to 1/3

To simplify this, it is easiest to make 1/3 into an equivalent fraction with the denominator 15 by multiplying both the numerator and the denominator by 5.

1 * 5 / 3 * 5 = 5 / 15

If we substitute in this new value, our ratio is:

4/15 : 5/15

Because both of these fractions have the same denominators, we can just compare their numerators, so we can simplify our ratio to be:

4:5

Therefore, your final answer is a 4:5 ratio of raisins to mixed nuts.

Hope this helps!

Answer

The problem is asking us to determine thew ratio of raisins to mixed nuts in the simplest form.

Solution & detailed explanation

Let's start.

We have two fractions here.

We would need to simplify both of the fractions, the LCM of both fractions is 15.

Since we now have the same denominators we could convert this into a ratio.

4:5

Therefore, the ratio of of raisins to mixed nuts is 4:5
