Answer:

165

Step-by-step explanation:

First we need to find the area of the field, A = r^2 * pi

The radius is 290 / 2 = 145 feet

A = 145 * 145 * 3.14 = <u>66018.5</u> sqr feet

One bag covers 400 sqr feet

Divide the Area by 400 sqr feet to find number of bags needed.

66018.5 / 400 = <u>165</u>

He will need at least 165 bags to cover the field

If rahul rows 16 km upstream and 24 km down steam taking 4 hours each, then the speed of the stream.
gladu [14]

The upstream speed is 4 km/hour and the down stream speed is 6 km/hour

<h3>Calculating Speed </h3>

From the question, we are to calculate the speed of each stream

From the given information,

"<em>Rahul rows 16 km upstream and 24 km down stream taking 4 hours each</em>"

For the Upstream,

Distance = 16 km

Time = 4 hours

Using the formula,

Speed = Distance/ Time

Speed = 16 km / 4 hours

Speed = 4 km/hour

For the Down stream,

Distance = 24 km

Time = 4 hours

Thus,

Speed = 24 km / 4 hours

Speed = 6 km/hour

Hence, the upstream speed is 4 km/hour and the down stream speed is 6 km/hour

Schach [20]

Answer:

Ah! Geometric sequences, Eh? Sucks I know....

Step-by-step explanation:

So first, we need to find the factor of this(been a while since I have done this)

r=\frac{24}{48} =\frac{1}{2}

So we found the relationship! Now we find the entire equation.

So we know the first term, 96, so let's use it!

a_{n} =96*(\frac{1}{2})^{n-1}

So there is the equation!

Now to find the 10th term.

a_{n} =96*(\frac{1}{2})^{n-1}\\a_{10} =96*(\frac{1}{2})^{9}\\a_{10} =96*\frac{1}{2^{9} } \\a_{10}=0.1875

There you have it!

Hope this Helps!

P.S. Stay Safe!
