Sixty-four percent of the students correctly described the process of photosynthesis. If 63 students did not correctly describe the process of photosynthesis, how many students did correctly describe the process?

Number of students who correctly describe the process = 112 students.

Step-by-step explanation:

From the information provided in the question;

64% correctly described the process of photosynthesis.

63 students didn't describe correctly the process of photosynthesis.

We are to find the number of students that did correctly describe the process of photosynthesis.

First of all we need to find the total number of students.Lets represent this value to be x

percentage of students who incorrectly describe the process = (100-64)%

=36%

x= 63*100/36

x=175 students.

FIRST METHOD

Number of students who correctly describe the process =

=

Number of students that correctly describe the process = 112 students.

SECOND METHOD

Number of students who correctly describe the process =  Total number of students- number of students who didn't correctly describe the process

Number of students who correctly describe the process = 175-63

Number of students who correctly describe the process = 112 students.

step-by-step explanation:

b and c

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}
