Which equation represents a population of 370 animals that decreases at an annual rate of 11% ?
kati45 [8]

The equation represents a population of 370 animals that decreases at an annual rate of 11% is p=370(0.89)^{t}.

<h3>What is an exponential function?</h3>

It is defined as the function that rapidly decreases and the value of the exponential function is always positive. It denotes with exponent y = a^x

where a is a constant and a>1.

Given that,

A population of 370 animals that decreases at an annual rate of 11%

a = 370, r = 11%

p = a(1-r)^{t}

 =  370(1-0.11)^{t}

p  =  370(0.89)^{t}

Hence, The equation represents a population of 370 animals that decreases at an annual rate of 11% is p=370(0.89)^{t}.

Penny makes $5,400 a month plus commission. She gets 3% of everything she sells. If Penny sold $62,000 worth of items this month
IrinaVladis [17]

Answer:

Her salary for the month = $7260

Step-by-step explanation:

Given

  • Base Salary = $5,400
  • Amount sold = $62,000
  • Percentage rate = 3%

To determine

  • Salary for month = ?

Given that Amount sold = $62,000 and Percentage rate 3%

so

Salary from commission rate = Amount sold × Percentage rate

                                                = $62,000 × (3 / 100) = $1860

  • Thus, the total salary can be calculated by adding Base salary and Salary from the commission rate.

so

Total salary = Base salary + Salary from commission rate

                   = $5,400 + $1860

                   = $7260

Hence, her salary for the month = $7260

What is 0.907 as a percent
PIT_PIT [208]
Since 1/100 is 1% or 0.01, then 0.9 is 90/100 or 90%. 0.907 is 907/1000 (we simply have the number and do 10^(numbers in the number after the decimal) for the denominator). or 90.7% (we have a decimal because it wouldn't make sense for it to be more than 1, but we know that it's not less than 90%

Question 1: Four expressions are shown below:
vekshin1

Answers;

Question 1 answer: The first and last option.

Question 1 explanation: 2(4x + 2) is 4x = 12 = 2 = 14 x 2 = 28 and 8x + 4 is 8 x 4 = 32 + 4 = 36 which is 8 more than 28 then, 3x = 9 + 2 + 3 x 2 = 28.

2(4x + 2) = 28 and 8x + 4 equals 36 which is 8 more and they're both equivalent to 2(3x + 2 + x) because 2(3x = 2 = x) equals 28.
