Lilly has $35,she went to the store and spender 10% of it,how much money she has left?
kirill115 [55]
Hi there! Lily has $31.50 left.

To find our answer we first need to know the amount of money Lily spend.
10\% \times 35 = 0.1 \times 35 = 3.50

Therefore, Lily spend $3.50. Now we subtract this amount of money from the amount she initially owned.


35 - 3.50 = 31.50
Hence, Lily has $31.50 left.

Mumz [18]

Answer:

(x-1)^2+(y-6)^2=9

Step-by-step explanation:

You use the center to get the left part of the equation and the radius to get the right.

The standard equation of a circle is

(x-h)^2+(y-k)^2=r^2

where r is the radius, and (h,k) are the coordinates of the center

The minute hand of a clock is 7 inches long. how far does the tip of the minute hand move in 35 minutes? if necessary, round the
dedylja [7]
An hour is 60mins or 1 rotation

so
the hand moves 35/60 of the circumference of the clock
so

c=2pir
r=length of hand=7
c=2pi7
c=14pi

then, we have 35 out of 60 mins or 35/60=7/12
7/12 times 14pi=98pi/12=49pi/6≈25.66 inches

The graph of a system of equations with the same slope and the same y-intercepts will have no solutions.
Liula [17]
I think the correct answer from the choices listed above is option C. <span>The graph of a system of equations with the same slope and the same y-intercepts will never have no solutions. Rather, it has an infinite number of solutions since all points of the lines intersects.</span>
