Answer:

The number of seashells he have in his collection all together is <u>140</u>.

Step-by-step explanation:

Given:

Stanley has a collection of seashells. He found 35% of his collection on Florida beaches.

Stanley has 49 seashells from Florida.

Now, to find the number of seashells of his collection altogether.

Let the number of seashells all together be $x.$

Percentage of seashells found on Florida beaches = 35%.

Number of seashells found on Florida beaches = 49.

Now, to get the number of seashells altogether we put an equation:

$35\%\ of\ x=49.$

⇒ $\frac{35}{100} \times x=49$

⇒ $0.35\times x=49$

⇒ $0.35x=49$

Dividing both sides by 0.35 we get:

⇒ $x=140.$

Therefore, the number of seashells he have in his collection all together is 140.

I can't see any diagram but the correct statement should be:
"Salinity decreases because the stream adds freshwater to the ocean"

The other statements are false.
F Salinity increases because the stream adds salt to the ocean
T Salinity decreases because the stream adds freshwater to the ocean
F Salinity increases because the stream adds freshwater to the ocean
F Salinity remains the same because the steam adds freshwater to the ocean
