Answer:
D) No, the hypotenuse should be 12.
Step-by-step explanation:
<em>Hypotenuse is the side opposite to the 90 degrees angle.</em>
<em>'6' is the opposite side to the given angle i.e. it is opposite from angle 30 degrees.</em>
<em>Step 1: Use the sin formula to find the hypotenuse.</em>
Sin (angle) = opposite/hypotenuse
<em>Step 2: Substitute the values in the formula</em>
Sin (30) = 6/hypotenuse
1/2 = 6/hypotenuse
hypotenuse = 6x2
hypotenuse = 12
Therefore, the answer is option D; No, the hypotenuse should be 12.

Multiply the bracket by -4
−4(3−1)+2
-12+4+2 : - negative sign and - negative sign = + positive sign
-12+6
= -6
Answer: -6
Answer:
The new volume is 7^3 or 343 times the old volume
Step-by-step explanation:
The original sphere has a volume of
V = 4/3 pi r^3
The radius is multiplied by 7
The new volume is
V = 4/3 pi (7r) ^3
V = 4/3 pi (7)^3 r^3
The new volume is 7^3 or 343 times the old volume
