What is 5.985 rounded to the nearest gram a.k.a just rounded?

1 answer:

6 0

The answer is 6. This one is tricky if you're rounding to the nearest tenth. You have 9 in the tenth's place and you look at the number to the right which is 8. 8 is near 10, so you round the 9 to a 10, but you can't make the final answer 5.10. That's impossible so instead, you make the 9 into a 0, and add the 1 to the 5. So, your final answer for that will be 6! :) Hope this helped!

A rope that is 245 cm long is cut into three pieces. The ratio of the lengths of the first piece to the second piece is 2:3, and

Olin [163]

Answer:

The length of longest piece is 105 cm.

Step-by-step explanation:

Given:

Rope is 245 cm long.

Ratio of lengths of first to second piece = 2:3.

Ratio of lengths of second to third piece = 4:5.

To find:

Length of longest piece = ?

Solution:

We are given the ratio of first and second pieces AND

ratio of second and third pieces.

Common link is second piece.

We need to make the ratio of second piece equal in both the ratio to find the ratio of all three pieces.

2:3

4:5

Multiply 1st ratio by 4 and 2nd ratio by 3:

Now, the ratio becomes:

8:12 and 12:15

And the ratio of three pieces can be represented as:

8: 12: 15, this ratio is the first piece: second piece: third piece

$\Rightarrow 8x+12x+15x = 245\\\Rightarrow 35x = 245\\\Rightarrow x = \dfrac{245}{35}\\\Rightarrow x = 7$

So, the pieces lengths will be

First piece = $8 \times 7 = 56$ cm

Second piece = $12 \times 7 = 84$ cm

Third piece = $15 \times 7 = 105$ cm

So, the length of longest piece is 105 cm.

Alex is writing statements to prove that the sum of the measures of interior angles of triangle PQR is equal to 180°. Line m is

Crank

Answer: The stuff in pink is the stuff I found based on the information given. The pink 40 comes from the blue 40. The reason that both of those angles are congruent is because they are alternate interior angles. This is the same reason about the angles whose measurements are 60. So the following things are true that we found that weren't already given: Angle PQR is 40 Angle PRQ is 60
