Answer:
33% or with 10th place decimal 33.3%
Step-by-step explanation:
1/3 has a continuous decimal form of .333333...
So, it is usually rounded to .33
Hope this helps!
Total students = 375 + 405 = 780
boys % = (375 / 780) *100%
=48.1 %
If you are doing a multi step question that looks something like this: 23+(4)-4 or longer. You will have to use a formula called BEDMAS. It stands for brackets, exponents( which are little numbers on top of a number), then you deal with division, multiplication, addition, and subtraction. You will have to solve your equation in this order. If you don’t you will get another, answer.
Answer:
4 gallons
Step-by-step explanation:
as martizas used up 3/4 gallons, we can calculate the fraction of gas left using: 1−3/4=1/4.
so now we use the fraction we calculated to times with the total volume of gas : 1/4×16=4 gallons
Answer:
a. y = 4,200 
b. 9.2%
Step-by-step explanation:
Given the information:
- The intinital value: 4,200
- The population is decreasing at a rate of 2.4% per year
=> the base number of the exponential function is:
100% - 2.4% = 97.6% = 0.976
Let t is quarter
Let y is the population
=> the following shows an exponential decay function to find the quarterly decay rate is:
y (t)= 4,200
b. The population is decreasing by how much percent per quarter?
Let t = 0 we have: y(0) = 4,200 
Let t = 1 we have: y(1) = 4,200 
=> the decreasing percentage is:
= (y(0) - y(1)) / y(0)*100%
= (4200 - 3811) / 4200 *100%
= 389/4200*100%
= 9.2%
