Two students, 100 meters apart on the same path, are
walking towards one other. Student A has a speed of 2
meters each second; Student B has a speed of 3 meters each
second. Let's suppose they start to walk to each other when
t=0. How many seconds will it take for the students to bump
into one another? Give your answer to the nearest whole
number.
Answers
Answer: 20
Step-by-step explanation:
first you make it into a equation
then you have to make both sides equal the same thing by doing that you figure what t is and t will be your answer
100=2(t)+3(t)
100=2(20)+3(20)
100=40+60
100=100
t=20
It will take 20 seconds for the students to bump into one another.
What is a system of equations?A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
Student A, has a speed of 2 meters each second;
Student B, has a speed of 3 meters each second.
Let's suppose they start to walk to each other when t=0.
first we will make it into a equation then we have to make both sides equal the same thing by doing that you figure what t is and t will be your answer.
100=2(t)+3(t)
100=2(20)+3(20)
100=40+60
100=100
t=20
Therefore, it will take 20 seconds for the students to bump into one another.

Trevor has an investment worth $6,774.50. He made his only deposit in it 22 years ago. Given that the investment yields 2.7% simple interest annually, how big was the initial deposit?
a. $2,524.50
b. $4,024.03
c. $4,250.00
d. $11,404.88
Answers
Answer:
First, converting R percent to r a decimal
r = R/100 = 2.7%/100 = 0.027 per year.Solving our equation:
P = 6774.5 / ( 1 + (0.027 × 22)) = 4250P = $4,250.00The principal investment required to get a total amount, principal plus interest, of $6,774.50 from simple interest at a rate of 2.7% per year for 22 years is $4,250.00I do exams and quizzes if your interested!The initial deposit amount is $4,250.00.
Given that,
The worth of an investment is $6774.50The time period is 22 years. The rate of interest is 2.7%.Based on the above information, the calculation is as follows:
We know that
[tex]SI =P\times R\times T\\\\SI = P\times 2.7\% \times 22\\\\SI = 0.594P[/tex]
Now
Investment worth = P + SI
= P + 0.594P
= 1.594P
So,
1.594P = 6774.50
P = $4,250
Therefore we can conclude that the initial deposit amount is $4,250.00.

Answers
Answer:

What is the minimum value for the function shown in the graph?
Answers
Answer:
2.5
The lowest point on the graph, or the minimum is at f(x)= 2.5
The minimum value of the given periodic function is, 2.5
What are functions?Function is a relation between a set of inputs and a set of outputs which are permissible. In a function, for particular values of x we will get only a single image in y. It is denoted by f(x).
Vertical line test:-
Whenever we want to check whether a given expression is a function or not we can apply a vertical line test, in this test we check for a single image of x , we are getting a single image or more.
If we get more images then it will not be a function.
For example, let us take, y² = 4ax
y = ±√4ax
For single value of x we get two values of y
Hence, it will not be a function.
Given that,
A periodic function,
Period = 3π
The value of the function is in the range of (2.5, 4.5)
So,
Maximum value = 4.5
Minimum value = 2.5
Thus, the minimum value is 2.5

Raul came home with $3.00 in his pocket. He had given Rene $1.50 on his way home. Pedro gave him $1.00 that he had borrowed last week. How much money did Raul have at the beginning of the day?
Answers
Answer: $3.50
Step-by-step explanation:
He came home with $3.00.
He gave Rene $1.50 which means that $1.50 was deducted from his money.
Pedro gave him $1.00 which added to his money.
Money he had therefore was:
= 3 + 1.50 - 1
= $3.50
