Answer:
Area of a rectangle is Width * Length
Apply this to each area the question asks for
AreaTop = 8cm * 4cm = 32
AreaBottom = the same, 32
AreaFront = 2cm * 4cm = 8
AreaBack = the same, 8
AreaLeftSide = 2cm * 8cm = 16
AreaRightSide = the same, 16
TotalSurfaceArea = 16 + 16 + 8 + 8 + 32 + 32 = 112
Answer:
0.72 litres
Step-by-step explanation:
Litres of syrup = 0.32 litres
Litres of water = 12 times the amount of syrup = 12 * 0.32 = 3.84 litres
Litres of orange squash = litres of syrup + litres of water
Litres of orange squash = (0.32 + 3.84) = 4.16 litres
Amount of orange squash litres split = 1.28 litres
Amount of orange squash left = (4.16 - 1.28) = 2.88 litres
Splitting the amount of squash left equally into 4 :
2.88 litres / 4 = 0.72 litres
Yes 3/4 is bigger than 1/4 3 is bigger than 1 so 3/4 is bigger.
Answer:
y = 2x +13
Step-by-step explanation:
when 2 lines are perpendicular, the product of the two gradients is -1
i.e. m x m1 = -1
so from 10y + 5x = 3, the gradient m is -0.5
m1 = -1 / -0.5 = 2
using m1 = 2 and pt(-7,-1),
the eqn is y = (m1)x +c
-1 = 2(-7) + c
c= 13
thus y = 2x +13
