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

PLEASE HELP AND SHOW WORK IF YOU CAN​
Murljashka [212]

Answer:

c) XY > RS

= true

Step-by-step explanation:

Firstly know the meaning of each sign given

> means <u>is greater than</u>

= means <u>is equal to</u>

a)XZ > ST

XZ = 8

ST = 11 - greater

= false

b) XY = RS

Due to the angles presented, we conclude that the greater the angle, the longer the unmeasured line.

XY is longer than RS

= false

c) XY > RS

= true

d) RS > XY

RS is shorter than XY hence not greater.

= false

Which expression is equivalent to 4+ [4 x (5-2)] + 2?
zimovet [89]

Answer:

<h2><u><em>A 4 + 12+2 = 18</em></u></h2>

Step-by-step explanation:

which expression is equivalent to 4+ [4 x (5-2)] + 2?

A 4 + 12+2

B 4 + 18 + 2

C 8x3 + 2

D 8 x 5 - 1

4+ [4 x (5-2)] + 2 = 18

A 4 + 12+2 = 18

B 4 + 18 + 2 = 24

C 8x3 + 2 = 26

D 8 x 5 - 1 = 39

check

4 + [4 x (5-2)]+ 2 = 4 + 12 + 2

18 = 18

the answer is good
