B is the answer because 9 times 2x is 18x and 9 times 5 is 45.
Answer:
∠ PQR = 55°
Step-by-step explanation:
∠ QPR = 74° ( vertical angles )
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the 2 given angles from 180°
∠ PQR = 180° - (74 + 51)° = 180° - 125° = 55°
Answer:
320 numbers with 3 digits that are odd
Step-by-step explanation:
Thickness of the plate before polishing = 2.342
Thickness of the plate after polishing. = 2.087
How much was removed = 2.342- 2.087 = 0.255
Hence , the answer 0.255 which is option B
Answer:
r = 5
Step-by-step explanation:
The formula for volume of a cone is ![\pi r^2*\frac{h}{3}](https://tex.z-dn.net/?f=%5Cpi%20r%5E2%2A%5Cfrac%7Bh%7D%7B3%7D)
h = 6
V = 50π
![2\pi r^2=50\pi](https://tex.z-dn.net/?f=2%5Cpi%20r%5E2%3D50%5Cpi)
r = 5
