Answer:

(B) 22

Step-by-step explanation:

The given expression is:

\frac{6(n^2+2)}{n}

Now, substituting the value of n=3 in the above expression, we get

=\frac{6((3)^2+2)}{3}

=\frac{6(9+2)}{3}

=2(9+2)

=2(11)

=22

Thus, the value of the given expression at n=3 will be 22.

Hence, option (B) is correct.

Write 4 and 1/4 as a percent
solniwko [45]

Answer:

425%

Step-by-step explanation:

4 can be written as 4.00 in decimal form. 1/4 can be written as 0.25 in decimal form. When changing a decimal into a percent, you move the decimal to the right two times. If we move the decimal point in 4.00 twice we get 400. If we move the decimal point in 0.25 twice we get 25. If we add 400 and 25 together, we get 425. Therefore, the answer is 425%. Hope this helped! :)

Split the surface area into geometric shapes as shown in the figure below.

Top part
The area of one triangle is
A₁ = (1/2)*(10 cm)*(4 cm) = 20 cm²
There are 3 of these triangles.

Vertical sides..
The area of one vertical side is
A₂ = (10 cm)*(6 cm) = 60 cm²
There 3 of them.

Bottom part
The triangle is equilateral with each side  = 10 cm, and each angle = 60 deg.
The area is (from the Law of Sines)  equal to
A₃ = (1/2)(10 cm)*(10 cm)*sin(60) = 43.3 cm²

The total surface area is
3A₁ + 3A₂ + A₃
= 3*20 + 3*60 + 4.3
= 283.3 cm²

Answer: The surface area is  283.3 cm²

0=4t-16t^2 Solve this please
vaieri [72.5K]

Answer:

\large\boxed{t=0\ \vee\ t=\dfrac{1}{4}}

Step-by-step explanation:

4t-16t^2=0\qquad\text{divide both sides by 4}\\\\\dfrac{4t}{4}-\dfrac{16t^2}{4}=\dfrac{0}{4}\\\\t-4t^2=0\\\\t(1-4t)=0\iff t=0\ \vee\ 1-4t=0\\\\1-4t=0\qquad\text{subtract 1 from both sides}\\\\-4t=-1\qquad\text{divide both sides by (-4)}\\\\t=\dfrac{1}{4}
