Answers

Answer 1

Answer: 16.7 is the answer rounded to the nearest tenth.

Answer 2

Answer:

Final answer:

The number 16.6666667 rounded to the nearest tenth is 16.7. Rounding is done by looking at the number to the right of the digit you're rounding to; if it's 5 or more, you round up.

Explanation:

The student is asking about rounding the number 16.6666667 to the nearest tenth. Rounding is used to make a number easier to work with. In this case, we will be rounding to the tenth place, which is one decimal place to the right of the decimal point.

The number in the tenth place here is 6. The number to its right is also 6. When the number to the right of the digit you are rounding to is 5 or more, you round up. Therefore, 16.6666667 rounded to the nearest tenth is 16.7.

Use the Distributive Property to expand the expression z(−6.4−3.5x)

Answers

Answer: $-6.4z-3.5xz$

Step-by-step explanation:

The distributive property is given by :-

$a(b+c)= ab+bc$

or $(b+c)a= ba+ca$ , where a, b , c are some algebraic expressions.

The given expression: z(−6.4−3.5x)

Then , by distributive property we have

$z(-6.4-3.5x)= z *-6.4 -z*3.5 x\n\n=-6.4z-3.5xz$

Thus , the required expression will be $-6.4z-3.5xz$

Order of operations:

2 • {390 – [5 • (10 – 4 ÷ 2)] + 15} • 2

Answers

so PEMDAS

the order of simplification/operation is
parenthaseese
exponents
multiplication or division whichever comes first
addition or subtraction whichever comes first

so we work the parenthasees inside to out

inside parenthaseese=(10-4/2)
so no exponents so skip
there's division so we do that
4/2=2/1=2
then we have
(10-2)
subtraction
10-2=8
(8)
next parenthaseese/bracket
[5 times (8)+15]
multiplication
5 times 8=40
[40]
other brackets
{390-[40]+15}
subtraction
390-40=350
{350+15}
350+15=365
outside
2 times {365} times 2
multiplication
2 times 365=730
730 times 2=1460

your answer is -542,340

2 * {390 - [ 5 *( 10 - 4 / 2)] + 15} * 2.
2*{390-[5*(8)]+15}*2
2*{390-[40]+15}*2
2*{390[-40]+15}*2
2* {-135,585}*2
{-271170}*2
-542,340

Round 691 to 1 significant figure!

Answers

Rounding to 1 significant figure means writing the number with only 1 non-zero figure.

Thus rounding 691 to 1 significant figure, means writing 691 as 700.

Answer: 700

Remark: if we were asked to round to 2 significant figure, we would round the number as 690

The correct answer is: 700

Explanation:

In order to round to 1 significant figure, ALWAYS REMEMBER, we will look at the first digit of the number, and make sure that it is not zero (zero case will be discussed at the end, as in this particular example zero is not the first digit).

In 691, the first digit at hundredth place is 6. Now we will look at the next digit. In this case, the next digit is 9, which is greater than 5, therefore, the 6 will round off to 7, and rest of the digits will become zero to round it off to one significant figure. Hence, the answer is 700.

(EXTRA INFORMATION) Zero case:

If we have the following number: 0.951. Now the first digit is 0, but as there is a decimal point after that, therefore, it is insignificant. We will move on to the first digit after the decimal point, which is 9 in this case. Now, we will look at the next number. In this case it is 5, therefore, 0.951 is closer to 1.0 after rounding off. Hence, in this case the answer will be 1.0.
