Answer:
3.50
Step-by-step explanation:
Necklace has beads and a pendant
b +p
There are 6 necklaces at a cost pf 43.80
6(b+p) =43.80
The beads for one necklace cost 3.80 so replace b with 3.80
6(3.80+p) =43.80
Divide each side by 6
6(3.80+p)/6 =43.80/6
3.80 +p = 7.30
Subtract 3.80 from each side
3.80+p-3.80 = 7.30 -3.80
p =3.50
Amount raised from selling candy bars = $ 1036.25.
Amount raised from dance ticket sales = $524 and
Amount raised from valentines flower sales = $206.58.
In order to find the amount your class raise altogether, we need to add all those amounts.
Total amount = $ 1036.25 + $524 + $206.58 = $1766.83.
Therefore, your class raise $1766.83 altogether.
Answer:
dy/dx= 7- 3x^-1/2
when X=1
dy/dx = 4
as it is a tangent M1=M2=4
now,
at gradient 4 and point (1,1)
equation of curve is ,
y-y1= m(x-x1)
or, y-1=4(x-1)
or, y-1=4x-4
or, y-4x= -3
or, 4x-y=3
The average rate of change of a continuous function, <span>f<span>(x)</span></span> , on the closed interval <span>[a,b]</span> is given by
<span><span><span>f<span>(b)</span></span>−<span>f<span>(a)</span></span></span><span>b−a</span></span>
First, do 36/12 to find out how many laps you can run in a certain amount of minutes. It is 1 laps per 3 minuted. Then, do 3 times 20 because 60 minutes is in an hour. Then, 1 times 20 is 20. 20 laps is the correct answer.
