4,400

The number 3 is in the hundredths place the 8 is behind the 3 so it’s larger than 5 so you turn the 3 into a 4(4,400) and turn all the numbers behind zero (4,400).

Sin60 =b/10
<span>√3/2 = b/10
</span>b = <span>√3 / 2 (10)
</span>b = 5<span>√3
</span>
d^2  = 10^2 - (5√3)^2
d^2 = 100 - 75
d^2 = 25
d = 5

sin30 = b/a
1/2 = 5√3  / a

a = 5√3 (2)
a = 10√3

c^2 = (10√3)^2  -  (5√3)^2
c^2 = 300 - 75
c^2 = 225
c = 15

so
a =10√3,  b = 5√3, c = 15,d = 5
answer is
D. last choice

9x^2 + 27xy - 4.75y^2=0
vichka [17]

You can solve this equation two ways:

Solve for x:

1) Factor with quadratic formula:

9(x-\frac{y}{6} )(x+\frac{19y}{6} )=0

2) Solve for x:

x=\frac{y}{6},-\frac{19y}{6}

Solve for y:

1) Factor with quadratic formula:

9(x-\frac{y}{6} )(x+\frac{19y}{6} )=0

2) Solve for y:

y=6x,-\frac{6x}{19}
