5(-3.4k - 7) + (3k + 21) = -17k - 35 + 3k + 21 = -14k - 14
Answer:
<h2>864π in³</h2>
Step-by-step explanation:
Volume of the water is equivalent to the volume of a cylinder = πr²h where;
r is the radius of the cylindrical tank
h is the height of the water
Given parameters
radius of the cylindrical tank r = 1feet = 12 inches
height of the water inside the tank = 6inches
Volume of the water = πr²h
Volume of the water = π(12)²*6
Volume of the water = π*144*6
Volume of the water = 864π in³
<em></em>
<em>Hence the volume of the water is 864π in³</em>
<u>64 + 69 + 73 + x </u> = 70<u>

206 + x</u>= 70<u>
</u> 4<u>
</u> x = (70 * 4) - 206
= 280 - 206
= 74
check: 6<u>4 + 69 + 73 + 74</u> = 70

Answer:
x ≈ 4.4 in
Step-by-step explanation:
The segment from the centre to the chord is a perpendicular bisector.
The third side of the right triangle = 7.4 ÷ 2 = 3.7
Consider the right triangle with legs 3.7 and 2.4 and hypotenuse x
Using Pythagoras' identity
x² = 2.4² + 3.7² = 5.76 + 13.69 = 19.45
Take the square root of both sides
x = 
≈ 4.4
