Menjawab:
1.1 cm
Penjelasan langkah demi langkah:
Volume kubus, V = a³
Dimana a = panjang sisi kubus
Untuk V = 1.331 cm³
Panjang sisi 'a' adalah:
V = a³
1,331 = a³
Ambil akar pangkat tiga dari kedua sisi
(1,331) ⅓ = a
a = 1,1 cm
Answer:
y = 50 + 25x.............(i)
y = 80 + 15x.............(ii)
x = 3
y = 125
Step-by-step explanation:
The tucker Gym charges a one time fee of $50 plus a $25 monthly membership charge.
The NoFo health club charges a one time fee of $80 plus a $15 monthly membership fee.
Let
number of month = x
total cost = y
Tucker Gym
y = 50 + 25x.............(i)
NoFo Gym
y = 80 + 15x.............(ii)
combining the equation
y = 50 + 25x.............(i)
y = 80 + 15x.............(ii)
y - 50 = 25x
y/25 - 2 = x
insert x in equation (ii)
y = 80 + 15(y/25 - 2)
y = 80 + 3y/5 - 30
y = 50 + 3y/5
y - 3y/5 = 50
5y - 3y/5 = 50
2y/5 = 50
cross multiply
2y = 250
y = 250/2
y = 125
insert y in equation (i)
125 = 50 + 25x
125 - 50 = 25x
75 = 25x
x = 75/25
x = 3
9)The triangles are congruent as they share all sides as seen with the lines (SSS)
10) they are not congruent as they only share 2 sides not all 3
11)they are congruent by using the Angle Side Angle, they share a vertices
12)they are congruent, by using the side angle side
13)They are congruent by using side side side, one is shared between the two
14)they are congruent by using the angle side angle
