Answer: T.S.A = 4512cm^2
volume = 18900cm^3
weight = 17.01 kg
Step-by-step explanation:
T.S.A of cuboid = 2(lb+bh+lh)
= 2(42x25 + 25x18 + 42x18)
=2(1050 + 450 + 756)
=2 x 2256
= 4512cm^2
to find weight, we've to find the volume of the ice cube
therefore, volume of a cuboid = lbh
=42 x 25 x 28
=18900cm^3
weight of 1cm^3 of ice = 0.9grams
therefore weight of 18900cm^3 of ice = 18900 x 0.9
= 17010 grams = 17.01kg

I don't see any triangle below
Answer:
The Angle Addition Postulate states that the measure of an angle is equal to the sum of the measures of the smaller adjacent angles that form the larger angle. Since the adjacent angles
∠
A
D
B
∠ADB and
∠
D
B
C
∠DBC form
∠
A
D
C
∠ADC, then by the Angle Addition Postulate
m
∠
A
D
C
=
m
∠
A
D
B
+
m
∠
D
B
C
m∠ADC=m∠ADB+m∠DBC.
Step-by-step explanation:
The roots of f(x) are the values for x at which f(x)=zero. The root of f(x) at point P is a bit redundant, since point P is the root of the function (and based on the graph, the only root).
We could plug zero in for f(x) to find the value of x at Point P, but based on the graph/options provided and the complexity of the function, it may be easier to just eyeball the graph to get the correct answer. We see that point P is between 1/2 and 1 on the x-axis.
Of the options provided, we want the value for x that satisfies: 1/2 < x < 1
a) 1/2 < 3/5 < 1 CORRECT ANSWER
b) 1/5 < 1/2 INCORRECT
c) 5/3 > 1 INCORRECT
d) 1/3 < 1/2 INCORRECT
Answer: it is the first option in the photo so A
