Sage belongs to a bird-watching club. Every two days, she goes out and counts the number of Black-hooded Parakeets she sees. The sightings can be approximated by the equation y = 1/2x + 3. What is the approximate rate of change for the number of parakeets seen?3

1/2

-1/2

7/2

Answers

Answer:

The rate of change for the number of parakeets seen is 1/2

Step-by-step explanation:

The sightings can be approximated by the equation:

y = (1/2)*x + 3

Which represents a line. Any line can be writen by an equation in the following form:

y = m*x + b

Where m is the slope of the lane or it's rate of change and b is the value for "y" when "x" equals zero. Applying this knowledge to the equation of the bird sightings we can se that the sightings grows 1/2 for every one unit that x grows, therefore the rate of change is 1/2.

The sales tax in your city is 4.4%4.4\%4.4%4, point, 4, percent, and an item costs $3\$3$3dollar sign, 3 before tax.How much tax would you pay on that item?
Round to the nearest hundredth or cent.

Answers

We are given original cost of the item excluding tax = $3.

Sale tax is 4.4% of the original cost of the item.

4.4% of 3 is = 0.044 × 3 = 0.132.

We need to round it to the nearest hundredth or cent.

So, we need to round 0.132 to two decimal places.

Therefore, 0.132 can be round to 0.13.

We needed to find the tax amount on the original cost of the item.

Therefore, $ 0.13 tax would you pay on that item of $3.

Answer:

its wrong

/12 bigger than 3/7

Answers

You can figure out if two fractions are bigger by just cross multiplying the numerator and denominator of each fraction.

$(5)/(12) (3)/(7)$

Multiply the 5 and 7, and then the 3 and 12. Be sure to start with the numerator of the first fraction.
$(5)/(12) (3)/(7)$
5 * 7 = 35, 3 * 12 = 36
So $(3)/(7)$ is bigger.

5/12 is not bigger than 3/7
