Which expression is equivalent to the radical expression shown below when it is simplified?
babymother [125]

Answer:

\sqrt{\frac{3}{64} } in simplified form is \frac{\sqrt{3}}{8}

Step-by-step explanation:

We need to solve the expression

\sqrt{\frac{3}{64} }

We know that \sqrt{\frac{a}{b}}=\frac{\sqrt{a}}{\sqrt{b}}

and 64 = 8*8

Solving we get

=\frac{\sqrt{3}}{\sqrt{64}}\\=\frac{\sqrt{3}}{\sqrt{8*8}}\\=\frac{\sqrt{3}}{\sqrt{8^2}}\\=\frac{\sqrt{3}}{8}

So \sqrt{\frac{3}{64} } in simplified form is \frac{\sqrt{3}}{8}

Which of the following choices is the explicit formula for the following geometric sequence?
jonny [76]
Common ratio (r) can be found by dividing the second term by the first term.
0.02 / -0.1 = -0.2

an = a1 * r ^ (n - 1)
a1 = first term = -0.1
r = common ratio = -0.2

an = -0.1(-0.2)^(n - 1)...answer is C

Tickets to a concert cost $50 for each orchestra seat and $40 for each
Vsevolod [243]

Answer:

H. the number of orchestra seat is 900

Step-by-step explanation:

Step one:

let the number of orchestra seat be x

and balcony seat be y

cost of orchestra= $50 each

cost of balcony =$40 each

total tickets= 1500

x+y= 1500----------1

amount earned= $69000

50x+40y=69000--------2

The system of equation for the situation is

x+y= 1500----------1

50x+40y=69000--------2

from 1, x=1500-y

put this in equation 2

50(1500-y)+40y=69000

75000-50y+40y=69000

-10y=69000-75000

-10y=-6000

divide both sides by -10

y=-6000/-10

y=600

put y= 600 in equation 1

x+600= 1500

x=1500-600

x=900
