The population of Oregon is about 4,000,000 what is the order of magnitude of this number? A) 6 B) 4 C) 3 D) 7

seropon [69]

Answer:

Step-by-step explanation:

Here, we are tasked with finding the order of magnitude.

What we are basically asked here is to write the number in powers of ten.

Thus

4,000,000 = 4 * 10^6

We can see that 10 is raised to the power of six here and thus we can say that the order of magnitude here is simply 6

In this picture B and F are midpoints.

Pavlova-9 [17]

now, we know that B and F are midpoints, namely BF is a midsegment of the triangle, and therefore BF || AE, so, the base AE is twice BF.

$\bf 2BF=AE\implies 2(23)=5x-4\implies 46=5x-4\implies 50=5x \\\\\\ \cfrac{50}{5}=x\implies \boxed{10=x}$

Surface area of hemisphere with diameter of 18

saul85 [17]

Answer:

In terms of pi: 243 $\pi$

in decimal form: 763.407

Step-by-step explanation:

to find surface area of a hemisphere the formula is,

$3\pi r^{2}$

diameter (d) = 18

radius = d / 2 = 18 / 2

radius = 9

$3\pi (9)^{2} \\3\pi (81)\\243\pi \\OR\\763.407$
