Answer:
-7
Step-by-step explanation:
you divide both sides by -2 and 14/-2 is equal to -7
Use the sine law: sinB/b = sinA/a
SinB = b*sinA/a
sinB = 3*sin120° /8
∠ B = 18.94° ≈ 19°
A : 10000 J
B: 625 J
C: 2500 J
Step-by-step explanation:
Step 1:
We know that ,
Kinetic Energy is given by ((1/2) × m × V²) J
where m = Mass of substance
V = Velocity
Step 2:
In first case, m= 50 kg, V=20 m/s
Kinetic energy = 0.5 × 50 × 20 ×20
= 10000 J
In second case, m= 50 kg, V=20 m/s
Kinetic energy = 0.5 × 50 × 5 ×5
= 625 J
In Third case, m= 50 kg, V=10 m/s
Kinetic energy = 0.5 × 50 × 10 ×10
= 2500 J
Answer:
volume = 36 cm³
Step-by-step explanation:
The volume of a rectangular prism = lwh
where
w = width
l = length
h = height
The base of a rectangular prism is a rectangle and the area of a rectangle is the product of length and width. Therefore,
base area of the rectangular prism = length × width
base area = lw
Base area of the rectangular prism = 12 cm²
Recall, the formula of the volume of a rectangular prism is the product of the length, width and height.
volume = lwh
substitute lw value in the formula above
volume = 12 × 3
volume = 36 cm³
Angela spends 120 more minutes walking her puppy over 2 days.
Given that Jarrett walks his puppy outside every day for 30 minutes, while Angela walked her puppy every day for 90 minutes, to determine how many more minutes does Angela spend walking her puppy over 2 days compared to Jarrett walking his puppy over 2 days the following calculation must be performed:
- 90 x 2 - 30 x 2 = X
- 180 - 60 = X
- 120 = X
Therefore, Angela spends 120 more minutes walking her puppy over 2 days.
