A turtle was swimming 2 feet below the surface of a pond. While looking for food, he went down 7 more feet.
Mekhanik [1.2K]

Answer: 9 feet below or -9 feet

Step-by-step explanation:

   Let us say 0 is the surface of a pond. The turtle started at -2 and then traveled -7 more. We will add these negative values to each other.

-2 + -7 = -2 - 7 = -9

          The turtle is now -9, or 9 feet below, the surface of the pond.

Counselors at Rockport High School and Riverdale High School surveyed the graduating seniors to find out their post-high-school
siniylev [52]

The percentage shows that they were 28% more likely to come from Riverdale High school.

<h3>How to calculate the percentage?</h3>

From the information given, the percentage of those from Rockport will be:

= 25/(25 + 44) × 100.

= 25/69 × 100

= 36.23%

The percentage of those from Riverdale will be:

= 44/(25 + 44) × 100.

= 44/69 × 100

= 63.77%

Therefore, the difference will be:

= 63.77% - 36.23%

= 28% approximately.

Expand<br> c(3c - 3)<br> I need help on this
Rudik [331]

\\ \sf\longmapsto c(3c-3)

Apply distributive law

  • a(b-d)=ab-ad

\\ \sf\longmapsto 3c(c)-3(c)

\\ \sf\longmapsto 3c^2-3c

We can still take common

\\ \sf\longmapsto 3c(c-1)
