3 l = _____ dl A. 0.3 B. 0.03 C. 300 D. 30

Andru [333]

Answer: The correct option is D, i.e.,30.

Explanation:

It the given equation we have two units l and dl.

Where l represents the liter and dl represents the deciliter. These are the volume units.

We know that,

1 liter = 10 deciliter

It means,

1 l = 10 dl

Multiply both sides by 3,

1\times 3 l = 10\times 3 dl

3 l = 30 dl

Therefore, the correct option is D and 3 l = 30 dl.

Please really need the correct answer for this or I'll fail algebra 3

trapecia [35]

Answer:

$4\pi$

Step-by-step explanation:

S = Arc Lenth

θ = Radians

R = Radius

S = θR

So, now that we understand the formula, we will convert 72° into radians by introducing the equation $x*\frac{\pi }{180}$ , x = 72

S = $72*\frac{\pi }{180} * R$

given that R = 10

S = $\frac{72*10*\pi }{180}$

S = $\frac{720*\pi }{180}$

We simplify 720 as 180 goes into 720 4 times and we get

S = $4\pi$

Hope this helps
