There are 10 million bacteria per square centimeter of coral in a coral reef. the coral reefs near the hawaiian islands cover 14,000 kilometers squared. how many bacteria are there in hawaii's coral reef?

Question Part D:

Today, coral reefs cover approximately 284,300 square kilometers. Corals depend on calcium carbonate to build their skeletons. Some scientists predict that by 2050, only 15% of coral reefs will have sufficient levels of calcium carbonate required for growth. By these estimates, how many square kilometers of coral reefs will be damaged by low calcium carbonate levels? Show your calculations.

Step-by-step explanation:

If 15% of coral reefs have the correct amount of calcium carbonate, then 85% of coral reefs will not: 100 – 15 = 85.

Multiply the area of the coral reefs by 85%: 284,300 sq. km × 0.85 = 241,655 sq. km

Based on these numbers, scientists predict that 241,655 square kilometers of coral reefs will be damaged by insufficient levels of calcium carbonate.

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.

the correct answer is

c. 4

step-by-step explanation:

the given polynomial is

the degree of the polynomial is the highest exponent which is 4.

the -4 is called the leading coefficient.

this polynomial has only one term so it is a monomial.

the correct answer is option c.
