it takes the earth 24 hours to complete a full rotation it takes Saturn 10 hours and 39 seconds to complete a full rotation how

OLEGan [10]

we know that

1 hour is--------> 60 minutes

1 minute is---------> 60 sec

10 hour =10*60=600 minutes

39 sec=39/60=0.65 min

10 h 39 sec=600+0.65=600.65 min

therefore

<u>the answer is</u>

600.65 minutes

If the sides of a triangle are 3, 4, and 5, then, to the nearest degree, the measure of the smallest angle of the triangle is...

Tju [1.3M]

Answer:

The smallest angle of the triangle is $37\°$

Step-by-step explanation:

we know that

If the sides of a triangle are $3$ , $4$ , and $5$ , then

we have a right triangle

because, applying the Pythagoras theorem

$5^{2}=3^{2}+4^{2}$

$25=25$ -------> is true

Remember that the measure of the smallest angle of triangle is the opposite angle to the smallest side

Let

A-------> the measure of the smallest angle

$tan(A)=3/4$

$A=arctan(3/4)=36.87\°$

Round to the nearest degree

$A=37\°$

Name a chord in circle O.

KatRina [158]

We are given a circle with center O.

We can see that we have a radius OB of given circle.

OC and OE are another two radii.

EC is a diameter of the circle.

<em>Diameter is the segment that cut the circle at two points and passes through center.</em>

AB is a tangent of the given circle.

<em>A tangent is a segment that cut a circle at one point only.</em>

But the chord is GD.

<em>A chord of a circle is the segment that cut a circle at two points.</em>

<h3>Therefore, a chord in circle O is GD.</h3><h3 />

Marcella bought 12/14 yards of ribbon. She uses 2 1/2 yards of ribbon for gift packages and 3 2/3 yards to tie balloons.

xenn [34]

Answer:

$6\frac{1}{12}\ yd$

Step-by-step explanation:

<u><em>The correct question is</em></u>

Marcella bought 12 1/4 yards of ribbon. She uses 2 1/2 yards of ribbon for gift packages and 3 2/3 yards to tie balloons.

How many yards of ribbon does Marcella have left?

we know that

To find out how many yards of ribbon Marcella has left, add up the yards of ribbon used for the gift packages plus the yards of ribbon used to tie the balloons. and subtract this result from the total yards of ribbon bought by Marcella

$12\frac{1}{4}-(2\frac{1}{2}+3\frac{2}{3})$

but first convert mixed number to an improper fractions

$12\frac{1}{4}=\frac{12*4+1}{4}=\frac{49}{4}$

$2\frac{1}{2}=\frac{2*2+1}{2}=\frac{5}{2}$

$3\frac{2}{3}=\frac{3*3+2}{3}=\frac{11}{3}$

substitute in the expression above

$\frac{49}{4}-(\frac{5}{2}+\frac{11}{3})$

$\frac{49}{4}-(\frac{5*3+2*11}{6})$

$\frac{49}{4}-(\frac{37}{6})$

$\frac{3*49-37*2}{12}$

$\frac{73}{12}\ yd$

Convert to mixed number

$\frac{73}{12}\ yd=\frac{72}{12}+\frac{1}{12}=6\frac{1}{12}\ yd$
