Explain when you know you need to rename a mixed number to subtract.

1 answer:

4 0

You know you need to rename a mixed number to subtract when the numbers involved have different denominators. In such a case. The lowest common multiple of the denominators will be calculated subsequent used to adequately rename the mixed numbers before subtraction can be done

Okay, so first, the quadrants on a coordinate plane go counter clockwise.

2 | 1

__________|__________

3 | 4

(1/2, -1.8) Would be a little to the right of the y axis, and a little below the x axis.

So, your answer would be D) Quadrant IV

Penelope has been practicing driving a golf ball. The lengths of her first 3 drives are shown below: • Drive 1: 180 yards • Driv

disa [49]

Answer:

The answer is "183 yards"

Step-by-step explanation:

$Drive \ 1= 180 \ yards \\\\Drive \ 2= 170 \ yards\\\\ Drive\ 3= 195 \ yards \\\\Drive \ 4= x \ \ yards \\\\$

Using formula:

$\to \text{average of number}=\frac{sum \ of \ number}{total\ number}\\\\\to 182 =\frac{180+170+195+x}{4}\\\\\to 4 \times 182 =545+x\\\\\to x= 728-545\\\\\to x=183$

a satellite's escape velocity is 6.5 mi/sec, the radius of the earth is 3960 mi, and the earth's gravitational constant is 32.2

Artyom0805 [142]

Answer:

$23.89x10^{6}$ ft

Step-by-step explanation:

$\frac{V^{2} }{R^{2} } = \frac{2g}{R+h} \\$ This is the formula to find satellite's escape velocity V , where R is earth's radius, h is the satellite's height from the earth surface and g is the earth's gravitational constant.
