1)Find the lcd for 1/8+5/6
=2/24+5*4/24
since the denominators are equal, combine the fractions
=3+4*5/24
=23/24

2)Convert the mixed numbers to improper
=15/8*17/5
=255/40
=51/8
=6 3/8

3)1/9 divided by 3
1/3*9
=1/27

4) 2 3/5* 2 6/35
13/5*76/35
13*76/175
988/175
=5 113/175

The answer is Slope = 0.750/2.000 = 0.375
x-intercept = 16/3 = 5.33333
y-intercept = 16/-8 = 2/-1 = -2.00000 hope this helps

a 12-ft ladder leans against a building so that the angle between the ground and the ladder is 74°. how high does the ladder rea

WINSTONCH [101]

Answer:

12 feet

Step-by-step explanation:

Sometimes, a simple drawing is a great way to start! In the attached drawing, the red line represents the ladder, the brown represents the ground, and the black represents the building!

We want to find the side of the triangle from where the ladder meets the building to where the building meets the ground. This can be found using trigonometric identities, namely sine:

$sin\theta=\frac{opposite}{hypotenuse}$

Plug in known values:

$sin(74^o)=\frac{x}{12}$

Rearrange to isolate the variable:

$x=12sin(74^o)$

Simplify!

$x=11.535140... ft$

Round to the nearest foot:

$x=12ft$

4) Given the line with equation 2x + 5y= 10 :

Svetlanka [38]

A. 2x + 5y= 10
5y= -2x+10
-> y= -2/5x+2

b. The slope is 2

c. For the y intecpet, x is always 0

y= -2/5x+2
y= -2/5(0)+2
y=0+2
y=2

(0,2) is the y-interecpt
