Depending on how flexibly you interpret "about 20 times larger" to mean, the answers are B and D.

Check the ratios of the larger number to the smaller number:

A: (2.01 x 10^7)/(4.25 x 10^6) = 2.01/4.25 x 10^1 = 20.1/4.25 = 4.729

B: (8.21 x 10^-3)/(4.13 x 10^-4) = 8.21/4.13 x 10^1 = 82.1/4.13 = 19.879

C: (4.91 x 10^6)/(5.09 x 10^3) = 4.91/5.09 x 10^3 = 4910/5.09 = 964.637

D: (5.97 x 10^4)/(3.12 x 10^3) = 5.97/3.12 x 10^1 = 59.7/3.12 = 19.135

I need the equation that passes through the point

Romashka-Z-Leto [24]

Answer:

y=4/3x+0

Step-by-step explanation:

slope intercept form works right?

y=mx+b

the m is the slope, and the problem gives us the slope. (4/3)

the b is the y intercept (where the line goes through the y) so on our coordinates, the second number is the y, so we have y=4/3x+b

Some group insurance plans cover ordinary doctor visits and dental work. true or false

Ede4ka [16]

True, but not many. Insurance companies typically have a cap off so the client doesn't go in let's say every week for a check up to see if they grew an inch. This is form personal experience in reading into the fine print.

If y=8 when x=3 when x=45

Veronika [31]

Answer:

The value of y for x = 45 is 120 .

Step-by-step explanation:

Given as :

Let The variables y and x are proportional to each others

I,e y ∝ x

Now , y = k x

So, for x = 3 , y = 8

I.e 8 = k × 3 ........1

∴ k = $\frac{8}{3}$

<u>Similarly </u>

for x = 45 , y = k × 3

I.e y = k × 45 ..........2

Now, putting the value of k in eq 2

So, y = $\frac{8}{3}$ × 45

I.e y = $\frac{8\times 45}{3}$

Or, y = 8 × 15

∴ y = 120

So, for x = 45 , y = 120

Hence The value of y for x = 45 is 120 . Answer
