So basically the number after the decimal is not considered a whole number. A whole number is basically a number that does not have a decimal. So if this was your number, 678.710392, the whole number of that would be 679 because the number 7 after the decimal is greater than 5.

If the number (after the decimal) is 5 - 9, then add the whole number by 1.

If it is 1 - 4 only, then do not add anything to the whole number.

Example:

0.7

Since the number after the decimal is 7, and 7 is in the range of 5 - 9, then add 0 by 1.

0.7 ≈ 1.0

3.46

Since the number is 4, and is in the range of 1 - 4, then just stay it like that

Find the square root of 1764 using prime factorization with explanation and solution.
musickatia [10]

Answer:

42

Step-by-step explanation:

The product of the prime factors of 1764 is

1764 = 2² × 3² × 7² , thus

\sqrt{1764}

= \sqrt{2^{2}(3^{2} )(7^{2} ) }

= \sqrt{2^{2} } × \sqrt{3^{2} } × \sqrt{7^{2} }

= 2 × 3 × 7

= 42

Novay_Z [31]

Answer:

3/8 was the swimming segment!

Step-by-step explanation:

We only need to subtract the bike and running segment from the total distance:

15 11/16 - 12 1/4 - 3 1/16

15.6875 - 12.25 - 3.0625 = 0.375 = 3/8

Need help please. Thanks so much.
Bingel [31]

Answer:

(-1,\frac{17}{6})

(3,\frac{3}{2})

(-5,\frac{25}{6})

Step-by-step explanation:

The given equation is 2x+6y=15

We substitute the ordered pairs to see which ones satisfies the equation.

For (-1,-8), we put x=-1 and y=-8 to get:

2(-1)+6(-8)=^?15

-2+-48=^?15\\-50=^?15

This is not true.

For (-1,\frac{17}{6})) we put x=-1 and y=\frac{17}{6} to get

2(-1)+6*\frac{17}{6})=15\\ -2+17=15\\15=15

This is true

For (3,3/2) we have 2(3)+6(3/2)=15

This implies 6+9=15

15=15

This is also True

For (-5,25/6), we have 2(-5)+6(25/6)=-10+25=15

This is also true.

z = 43º

sin43 = opp/hyp

sin43 = 35/y

y = 35/sin43

y = 51.32º
