Answer: 781,250

Step-by-step explanation: Begin by studying the pattern.

Here, notice that 10 × 5 is equal to 50.

In the same way, 50 × 5 is equal to 250.

Continuing the same pattern, 250 × 5 is equal to 1,250.

1,250 × 5 is equal to 6,250.

6,250 × 5 is equal to 31,250.

31,250 × 5 is equal to 156,250.

156,250 × 5 is equal to 781,250.

This means that the 8th term in this pattern is 781,250.

First, lets find the common ration between the first 3 terms.

50 / 10 = 5

250 / 50 = 5

Second, multiply the common ration to each term to find the next term.

First term: 10

Second term: 10 * 5 = 50

Third term: 50 * 5 = 250

Fourth term: 250 * 5 = 1,250

Fifth term: 1,250 * 5 = 6,250

Sixth term: 6,250 * 5 = 31,250

Seventh term: 31,250 * 5 = 156,250

Eigth term: 156,250 * 5 = 781,250

Thus, the 8th term of the geometric sequence is 781,250

Best of Luck!

Let A be (x1,y1) , B be (x2,y2) , P be (x,y) and the ratio be m:n

Formula is,

x=(x2*m+x1*n)/(m+n)

y=(y2*m+y1*n)/(m+n)

In a camp there is food for 400 persons for 23 days-if 60 more persons join the camp find the number of days the provision will

Deffense [45]

The answer is 20 days.

After 60 people have joined there will be 460 people in the camp.

The number of days which the provisions will last will be proportional less after the 60 people have joined and will be:-

(400/460) * 23

= (20 / 23) * 23

= 20

WILL GIVE BRAINLIEST ANSWER!!

Natasha2012 [34]

Check the picture below.

now, bear in mind that, there are 60minutes in 1 degree, so 23' is just 23/60 degrees or about 0.38 degrees.

and 29' is just 29/60 degrees or about 0.48 degrees.

so 16°23' is about 16.38°, and 49°29' is about 49.48°

$\bf tan(16.38^o)=\cfrac{200}{a+b}\implies a+b=\cfrac{200}{tan(16.38^o)}
\\\\\\
\boxed{b=\cfrac{200}{tan(16.38^o)}-a}
\\\\\\
tan(49.48^o)=\cfrac{200}{b}\implies \boxed{b=\cfrac{200}{tan(49.48^o)}}\\\\
-------------------------------\\\\
\cfrac{200}{tan(49.48^o)}=\cfrac{200}{tan(16.38^o)}-a\\\\\\a=\cfrac{200}{tan(16.38^o)}-\cfrac{200}{tan(49.48^o)}$

make sure your calculator is in Degree mode.
