Answer:
B. 12π ft.³
Step-by-step explanation:
volume of cylinder = πr²h
= π × 2² × 3
= π × 4 × 3
= 12π
<span>an equation that expresses the gross weight of an aircraft as a function of its landing speed will be given as follows:
</span><span> V= √1.223w
we make w the subject of the equation, we start by dividing both squaring both sides:
</span>V²=(√1.223w)²
V²=1.223w
next we divide both sides by 1.223 to get :
V²/1.223=1.223w/1.223
w=V²/1.223
hence the answer will be w=V²/1.223
Answer:
11
Step-by-step explanation:
42 is also the degree for x so 42+42=84
there are 360 total degrees in a parallelogram
360-84=276
276 is divided by 2 as y and w are the same degrees
138 + 5 to find x and that is 143
143/13 is 11
Scalar multiplication of a matrix refers to the

addition of the same matrix.
Answer: x = 6.46153846
Step-by-step explanation:
We are given the equation <em>13x - 4 +100 = 180</em>, and we must find the value of <em>x</em>. In order to do that get x on on one side by itself and a constant on the other side by itself.
This first step is to combine like terms. <em>13x</em> is by itself. <em>-4 + 100 = 96</em>. This gives us the equation <em>13x +96 = 180</em>.
In order to get <em>x </em>by itself, subtract 96 from each side of the equation. This gives us the equation 13x = 84.
Next, divide each side by 13 to find x. This gives us x = 6.46153846
Hope this helps! Have a nice day!
