Answer:

B

Step-by-step explanation:

No need to panic, it's much more simpler than you think.

10^4 = 10,000

10^3 = 1,000

(7.1 * 10,000) * (4.8 * 1,000) =

(7.1 * 4.8) * (10^3 * 10^4) =

= 34.08 * 10^7

<h2>= 3.408 * 10^8</h2>

A number divided by three less two is at most two
Marina CMI [18]

x ≤ 12

Solution:

Let us take the number be x.

A number : x

A number divided by three : $\frac{x}{3}

A number divided by three less two : $\frac{x}{3}-2

A number divided by three less two is at most two : $\frac{x}{3}-2\leq 2

Now, simplify the inequality,

$\Rightarrow\frac{x}{3}-2\leq 2

Add 2 on both sides of the inequality,

$\Rightarrow\frac{x}{3}-2+2\leq 2+2

$\Rightarrow\frac{x}{3}\leq 4

Multiply by 3 on both sides of the equation,

$\Rightarrow\frac{x}{3}\times3\leq 4\times3

$\Rightarrow x\leq 12

Hence x ≤ 12.

If a circle has a diameter of 4 inches, what is the area?
gulaghasi [49]
The formula for area of a circle is π × radius^2, and to find the radius we can just divided the diameter by 2 and get 2 inches. You don't need to use a calculator here, because π is approximately equal to 3.14, so 3.14 × 2^2 = 12.56, which is answer B. I hope this helps!
