Dan's science magazine has a mass of 256.674 grams. What is the mass of his magazine rounded to the nearest tenth?

The tenth place is the .6. Look over at the number next to it, the 7. It's greater than 5 so make the .6 one digit greater. Now your answer is 256.7

The answer is 256.7

You round the .67 off to .7

The .6 in 256.674 is in the tenth place. You are rounding off that number. If the number next to it is greater then 5, you round up. If it's less then 5 you keep it the same.

Answer:

Step-by-step explanation:

Hello, please consider the following.

$x^2+x-42\\\\\text{The sum of the zeroes is -1=-7+6 and the product is -42=-7*6.}\\\\\text{So, we can factorise.}\\\\x^2+x-42\\\\=x^2+7x-6x-42\\\\=x(x+7)-6(x+7)\\\\=(x+7)(x-6)$

So, the possible dimensions of the rectangle are (x+7) and (x-6).

Thank you.

KengaRu [80]

Answer:

$12+17+y+z$ or $29+y+z$ .

Step-by-step explanation:

We have been given that Nigel is planning his training schedule for a marathon over a 4-day period. He is uncertain how many miles he will run on two days. One expression for the total miles he will run is $12+y+17+z$ .

The Commutative Property of Addition states that we can add numbers in any order. For example a and b be two numbers.

According to Commutative Property of Addition $a+b=b+a$ .

Similarly, we can write an equivalent expression to our given expression as:

$12+17+y+z$

We can simplify our expression as:

$29+y+z$ .

Therefore, our required expression would be $12+17+y+z$ or $29+y+z$ .
