Complete Question

What is ragsak speed in feet per second round to the nearest tenth. (ragsak speed 31.8 miles/hour)

Answer:

46.6 feet per second

Step-by-step explanation:

Ragsak speed = 31.8 miles

Step 1

Convert from miles per hour to feet per hour

1 mile = 5280 feet

31.8 miles =

= 31.8 miles × 5280 feet/ 1 mile

= 167904 feet/hour

Step 2

Convert from feet/ hour to feet/second

1 hour = 60 minutes

1 minute = 60 seconds

1 hour = 60 × 60

= 3600 seconds

Hence

167904 feet/hour = 167904 feet/3600 seconds

= 46.64 feet / second or 46.64 feet per second

Approximately to the nearest tenth, Ragsak's speed = 46.6 feet per second

Explain how you know 12.6, 3.1, 5.4, greater than 20

USPshnik [31]

<span>Given numbers 12.6, 3.1 and 5.4
=> 12.6
=> 3.1
=> 5.4
These 3 are all smaller than 20.
Explain why is it greater than 20?
Very simple, simply add those given numbers
=> 12. 6 + 3.1 = 15.7
=> 15.7 + 5.4 = 21.1
=> 21.1 > 20 , 20 is less than 21.1
That’s that reason why the given numbers is greater than 20. When you add the 3 numbers, the sum is greater than 20.</span><span>

G(x)=1/6(8)^x-5. x=9

Nezavi [6.7K]

Answer:

$g(9) = \frac{2048}{3}$

Step-by-step explanation:

Given

$g(x) = \frac{1}{6}(8)^{x-5}$

$x = 9$

Required

Solve

Substitute 9 for x in $g(x) = \frac{1}{6}(8)^{x-5}$

$g(9) = \frac{1}{6}(8)^{9-5}$

$g(9) = \frac{1}{6}(8)^{4}$

Remove bracket

$g(9) = \frac{1}{6}* 8^4$

$g(9) = \frac{1}{6}* 4096$

$g(9) = \frac{1* 4096}{6}$

$g(9) = \frac{4096}{6}$

Simplify fraction

$g(9) = \frac{2048}{3}$

A Web site defines a regular polygon as “a polygon with all angles the same measure.” Is this definition valid?

grandymaker [24]

Answer:

Yes, because all regular polygons fit this definition.

Choice D is correct

Step-by-step explanation:

A polygon is said to be regular if it is equiangular that is all its angles are equal and equilateral which implies that all its sides have equal length. Examples of regular polygons include;

Regular pentagon

Regular octagon

the speed of a stream is 4mph. If a boat travels 92 miles downstream in the same time that it takes to travel 46 miles upstream,

Elanso [62]

Answer:

12 miles per hour

Step-by-step explanation:

Let speed of boat in still water be "x"

and speed of current be "c"

So, downstream rate would be "x + c"

And, upstream rate would be "x - c"

Now, given c = 4

We can use the distance formula, D = RT, where

D is distance, R is rate, and T is time

to solve this.

Downstream:

D = RT

92 = (x+4)(t)

Upstream:

D = RT

46 = (x-4)(t)

Both the times are same, we can equate both the times. Lets simplify first:

t = 92/(x+4)

and

t = 46/(x-4)

Equate:

$\frac{92}{x+4}=\frac{46}{x-4}$

Now, cross multiply and solve for x to get our answer:

$\frac{92}{x+4}=\frac{46}{x-4}\\92(x-4)=46(x+4)\\92x-368=46x+184\\46x=552\\x=12$

Speed of Boat (in still water) = 12 mph
