Answer:

I believe your answer would be the following:

A) 250 miles in 5 hours.

C) 200 miles in 4 hours

E) 700 miles in 14 hour

Step-by-step explanation:

Unit rate = 50

A) 250 miles in 5 hours // 50*5 = 250 (CORRECT)

B) 300 miles in 5 hours // 50*5 ≠ 300 (WRONG)

C) 200 miles in 4 hours // 50*4 = 200 (CORRECT)

D) 240 miles in 4 hours // 50*4 ≠ 240 (WRONG)

E) 700 miles in 14 hours // 50*14 = 700 (CORRECT)

Hope this helps! :)

<h3>Answers: Choice A, Choice C, Choice E</h3>

=========================================================

Explanation:

We use this formula

speed = distance/time

to divide each pair of values given.

For choice A, we have speed = distance/time = 250/5 = 50 mph which shows choice A is one of the answers.
Choice B doesn't work though because 300/5 = 60 mph.
Choice C works since 200/4 = 50 mph.
Choice D doesn't work: 240/4 = 60 mph
But choice E does work: 700/14 = 50 mph

To summarize, we got the following speeds

A) 50 mph
B) 60 mph
C) 50 mph
D) 60 mph
E) 50 mph

In a right triangle, CosA=0.352 and SinA=0.936 What is the approximate value of tanA?

mr_godi [17]

$\tan A=\frac{\sin A}{\cos A}$

Proof: $\sin\div\cos=\frac{o}h\div\frac{a}h=\frac{o}h\times\frac{h}a=\frac{oh}{ha}=\frac{o}a=\tan$

$\cos A=0.352,\ \sin A=0.936$

$\tan A=\frac{0.936}{0.352}$

$\boxed{\tan A=2.65\overline{90}}$ <em>(round as needed)</em>

Answer:

"To the nearest year, it would be about 9 years"

Step-by-step explanation:

11c)

This is compound growth problem. It goes by the formula:

$F=P(1+r)^t$

Where

F is the future amount

P is the present (initial) amount

r is the rate of growth, in decimal

t is the time in years

Given,

P = 20,000

r = 8% = 8/100 = 0.08

F = double of initial amount = 2 * 20,000 = 40,000

We need to find t:

$F=P(1+r)^t\\40,000=20,000(1+0.08)^t\\2=(1.08)^t$

To solve exponentials, we can take Natural Log (Ln) of both sides:

$2=(1.08)^t\\Ln(2)=Ln((1.08)^t)$

Using the rule shown below we can simplify and solve:

$Ln(a^b)=bLn(a)$

We can write:

$Ln(2)=Ln((1.08)^t)\\Ln(2)=tLn(1.08)\\t=\frac{Ln(2)}{Ln(1.08)}\\t=9.0064$

To the nearest year, that would be about 9 years

Tissues of living organisms consist primarily of organic compounds; that is, they contain carbon molecules known as proteins, ca

Marianna [84]

<span>A healthy human body is approximately 18% carbon, so to determine how many pounds of carbon a 200lb body contains, compute 200lbs X 0.18 = 36 pounds. To convert 36lbs to kilograms, multiply by the conversion factor 0.454. Therefore, 36lbs X 0.454 = 16.344 kg.</span>
