Answer:

0.29 rounded to the nearest ones is 0.

0.29 rounded to the nearest tenths is 0.3

0.29 rounded to the nearest hundredths is 0.29

Step-by-step explanation:

Note that when rounding, you always look at the place value directly next to the one you are rounding. Note that if the digit is 5 or greater, round up; If 4 or less, round down.

Round to the nearest ones:

Look at the place value directly next to the ones (tenths place value). It is a 2. Because 2 is less than 5, round down:

0.29 rounded to the nearest ones is 0.

Round to the nearest tenths:

Look at the place value directly next to the tenths (hundredth place value). It is a 9. Because 9 is greater than 5, round up:

0.29 rounded to the nearest tenths is 0.3

Round to the nearest hundredths:

Look at the place value directly next to the hundredths (thousandths place value). Because there is no number, it is typically signified by a 0 (place holder).

0.29 rounded to the nearest hundredths is 0.29

We know the following about the numbers a, b and c:

labwork [276]

Step-by-step explanation:

(a + b)² = 9

(b + c)² = 25

(a + c)² = 81

Taking the square root:

a + b = ±3

b + c = ±5

a + c = ±9

By adding these three equations together and dividing both sides by 2, we get the value of a + b + c.

Possible combinations for a + b + c such that the sum is greater than or equal to 1 are:

a + b + c = (-3 + 5 + 9)/2 = 11/2

a + b + c = (3 − 5 + 9)/2 = 7/2

a + b + c = (3 + 5 + 9)/2 = 17/2

Select the two values of x that are roots of this equation x^2-5x+2=0

Nataly [62]

The roots of the equation is x = 4.56 OR x = 0.44

<h3>Quadratic equation</h3>

From the question, we are to determine the roots of the given equation

The given equation is

x² -5x +2 = 0

Using the formula method,

$x =\frac{-b \pm \sqrt{b^{2}-4ac } }{2a}$

In the given equation,

a = 1, b = -5, c = 2

Putting the values into the formula,

$x =\frac{-(-5) \pm \sqrt{(-5)^{2}-4(1)(2) } }{2(1)}$

$x =\frac{5 \pm \sqrt{25-8} }{2}$

$x =\frac{5 \pm \sqrt{17} }{2}$

$x =\frac{5 + \sqrt{17} }{2}$ OR $x =\frac{5 - \sqrt{17} }{2}$

$x =\frac{5 + 4.12}{2}$ OR $x =\frac{5 - 4.12}{2}$

$x =\frac{9.12}{2}$ OR $x =\frac{0.88}{2}$

x = 4.56 OR x = 0.44

Hence, the roots of the equation is x = 4.56 OR x = 0.44

Kevin needs to convert 620 millimeters per minute to meters per hour. Which conversion factors should he use?

Annette [7]

Try this option:
1 meter=1000 mm; 1 hour=60 min. From another side: 1 mm=0.001 m. and 1 min=1/60 h.
Using this rule:
620 mm/h=0.06*620 m/h=37.2 meters per hour.

answer: 0.06

Y - 8 = -10<br> How do I verify the solution ?

prisoha [69]

Answer:

y = -2

Step-by-step explanation:

<u>SOLUTION :-</u>

Solve the equation.

Add 8 to both sides in order to isolate the equation.

$=> y - 8 + 8 = -10 + 8$

$=> y = -2$

∴ y = -2

<u>VERIFICATION :-</u>

To verify the solution of y , just put the solution (y = -2) in place of y in equation and check whether L.H.S = R.H.S.

L.H.S :-

-2 - 8 = <u>-10</u>

R.H.S. :-

<u>-10</u> (already given)

⇒L.H.S. = R.H.S. (verified)
