The second one and the fourth one.

Step-by-step explanation:

As the problem states, it takes 166.5 gallons of water in 3 mins. Since it states it is a proportional relationship, we know that 166.5/3 is the number of gallons pumped in 1 minute. We can write this as g(the number of gallons) = 166.5/3 * m(the number of minutes) ! In additon, 166.5/3 is equivalent to 55.5, which gives us the second and the fourth equation correct!

An ostrich run 6 mile in12 minut how far he could come in 40 minutes

bogdanovich [222]

The ostrich can run 20 miles in 40 minutes.

Solution:

Given that, An ostrich run 6 mile in 12 minutes

We have to find how far he could come in 40 minutes

Now, according to the given information

Ostrich runs 6 miles ⇒ 12 minutes

Then, “n” miles ⇒ 40 minutes

Now, by criss cross multiplication we get,

$\begin{array}{l}{\rightarrow 6 \times 40=n \times 12} \\\\ {\rightarrow 40=n \times 2} \\\\ {\rightarrow n=20}\end{array}$

Hence, the ostrich can run 20 miles in 40 minutes

AnnZ [28]

What is the 9th term of the geometric sequence 4, -20, 100, ...
First term, a = 4 
common ratio, r = –20 / 4 = –5 
..... ..... ..... ..... = 100 / –20 = –5 
9th term = 4 ( –5 ) ^ ( 9 - 1 ) 
..... ...... = 4 ( –5 ) ^ 8 
..... ...... = 4 ( 390,625 ) 
..... ...... = 1,562,500
