Answer:

10 quarters and 15 dimes

Step-by-step explanation:

25 = Quarters +  Dimes

Total worth = $4.00 =  0.25* Quarter +  0.1*Dimes

so...

25 = Q + D ,     D = 25 - Q

4 =  0.25*Q + 0.1 * (25 - Q)

4 = 0.25 * Q + 2.5 - 0.1*Q

1.5 = 0.15Q

Q = 10

D = 15

If a roasting is 600mm x 500mm how many 25cm cake time will fit on it?
nydimaria [60]
So assuming that 25cm is 25 square cm because you cannot have a 2 dimentional cake so

600mm by 500mm
to find the area, multiply legnth by width

mm=milimeters
cm=centimeters
this is in mm so
1cm=10mm
1mm=1/10cm
to convert from mm to cm, you divide by 10
we must divide by 10 first
legnth =600mm
600/10=60cm
legnth=60cm

width=500mm
500/10=50cm
width=50cm

area=60 times 50=3000 square cm or cm^2
so 3000 is the area
25 is the area of each cake
divide 3000 into 25 and find how many cakes will fit

3000/25=120

120 cakes will fit
