Answer:

this is simple. you just multiply and divide and stuff. if 3/10 is the ratio, you need to find what 3/10 is, but out of 60. there for: 18 mins. 3 for each 10.

Than, you can simply multiply is by two, (for the second hour) and get the final answer: 36

Step-by-step explanation:

When they say solve the product in the lowest terms what do they mean?
m_a_m_a [10]

when people say " in lowest terms" they usually mean like the simplified version of an answer

an example of this would be like

make \frac{2}{4} into lowest terms

the answer would be \frac{1}{2}

if you dont understand comment on this and ill try to break it down more

The radius of the Earth is approximately 3,960 miles. Find the approximate surface-area-to-volume ratio of the Earth.
Jobisdone [24]
To put it another way, that ratio exists, no matter what distance units you use to express lengths, such as the radius of the Earth, but using different units will result in a different numerical part. 
<span>You can't, for instance, say the the radius of the Earth is 3960, and leave it at that. </span>
<span>If someone comes along who's measuring everything in km, he'll tell you that it's 6373. </span>
<span>Or if he's using meters, he'll say it's 6,373,000. </span>
<span>Or in yards, 6,969,600. </span>

<span>So r = 3960 mi </span>
<span>And as others have said, the area, A, and volume, V, of a sphere, in terms of its radius, are </span>
<span>A = 4πr² </span>
<span>V = 4πr³/3 </span>
<span>so that the area to volume ratio is </span>
<span>A/V = 3/r </span>

<span>So the answer is </span>
<span>3/(3960 mi) = (1/1320) /mi. </span>

In ΔUVW, the measure of ∠W=90°, UV = 6.2 feet, and WU = 1.2 feet. Find the measure of ∠V to the nearest tenth of a degree.
Crazy boy [7]

Answer:

m<V = 11.2 degrees

Step-by-step explanation:

In ΔUVW, the measure of ∠W=90°, UV = 6.2 feet, and WU = 1.2 feet.

From the triangle;

UV = hypotenuse = 6.2feet

WU = opposite = 1.2feet

Required

m<V

Using the SOH CAH TOA identity

sin m<V = opp/hyp

sin m<V = WU/UV

sin m<V = 1.2/6.2

sin m<V = 0.1936

m<V = arcsin(0.1936)

m<V = 11.16

m<V = 11.2 degrees ((to the nearest tenth of a degree)
