Answer:

1, 2, 4

Step-by-step explanation:

4 1/12·2 2/3 = 49/12·11/4 = 49/12·33/12 = 1617/144 = 11 11/48 Good
2 1/5·6 1/4 = 11/5·25/4 = 44/20·125/20 = 5500/400 = 13 3/4 Good
1 1/2·3 1/5 = 3/2·16/5 = 15/10·32/10 = 480/100 = 4.8 Doesn't Work
3/4·8 1/5 = 3/4·41/5 = 15/20·164/20 = 2460/400 = 6 3/20 Good
5 1/2·5 = 11/2·5 = 55/2 = 27 1/2 Doesn't Work

(Note: Division of big numbers should be done by simplification, although not shown here.)

Find the value of x and the value of y.

Elan Coil [88]

Answer:

Step-by-step explanation:

According to the diagram ,

Hypotenuse = 10√3

Opposite = x

Adjacent = y

α = 60

Using SOHCAHTOA ,

Sin α = opp / hyp

Sin 60= x/10√3

√3/2= x/10√3

x = 15

Pythagoras theorem ;

Hypotenuse ^2 = Opposite ^2 +Adjacent ^2

10√3 ^2 = 15^2+ y^2

300 = 225 +y ^2

300 -225 = y^2

75 = y^2

y = √75y

y = 5√3

Write the equation for the perpendicular bisector of the given line segment.

Anon25 [30]

Answer:

$y=\frac{1}{3}x+\frac{5}{3}$

Step-by-step explanation:

Let

A(-5,5),B(-2,-4) ----> the given segment

step 1

Find the slope AB

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

substitute the given values

$m=\frac{-4-5}{-2+5}$

$m=\frac{-9}{3}$

$m=-3$

step 2

we know that

If two lines are perpendicular, then their slopes are opposite reciprocal (the product of the slopes is equal to -1)

the slope of the perpendicular bisector is equal to

$m_1*m_2=-1$

we have

$m_1=-3$

substitute

$(-3)*m_2=-1$

$m_2=\frac{1}{3}$

step 3

Find the midpoint segment AB

A(-5,5),B(-2,-4)

The formula to calculate the midpoint between two points is equal to

$M(\frac{x1+x2}{2} ,\frac{y1+y2}{2})$

substitute the values

$M(\frac{-5-2}{2} ,\frac{5-4}{2})$

$M(-\frac{7}{2} ,\frac{1}{2})$

step 4

Find the equation of the line in point slope form

$y-y1=m(x-x1)$

we have

$m=\frac{1}{3}$

$M(-\frac{7}{2} ,\frac{1}{2})$

substitute

$y-\frac{1}{2}=\frac{1}{3}(x+\frac{7}{2})$

step 5

Convert to slope intercept form

$y=mx+b$

isolate the variable y

$y-\frac{1}{2}=\frac{1}{3}x+\frac{7}{6}$

$y=\frac{1}{3}x+\frac{7}{6}+\frac{1}{2}$

$y=\frac{1}{3}x+\frac{10}{6}$

simplify

$y=\frac{1}{3}x+\frac{5}{3}$
