Answer:
So the decay percentage rate is of 70.8%
Step-by-step explanation:
An exponentil function has the following format:
In which c is a constant.
If a>1, we have that a = 1 + r and r is the growth rate.
If a<1, we have that a = 1 - r and r is the decay rate.
In this problem:
a = 0.292
A is lesser than 1, so r is the decay rate.
1 - r = 0.292
r = 1 - 0.292
r = 0.708
So the decay percentage rate is of 70.8%
Answer:
The total cost of the party is approximately $2300, hence the correct answer is option D.
Step-by-step explanation:
Given:
Number of students = 295 students
cost per student = $8.95
Discounts given by the company = $400
To find:
We need to estimate the total cost of the party.
Solution:
To find the total cost of the party we need to multiply the total number of students into the cost per student.
This can be done as follows:
=295×8.95
=2640.25
Therefore, the total cost of the party is $2640.25, but it is given that the laser tag company gave the students a discount of $400. Hence the total cost after discount is
=2640.25-400
=2240.25
Therefore, the total cost of the party is approximately $2300
Hence the correct answer is option D.

Step-by-step explanation:
25 - 19.28 = 5.72
5.72 × 100 to change from dollar to cents
572
572 ÷ 13 = 44 yards of ribbon karen bought
The radius of the circle is y=-25/14
OK , let me start from here ,
As you have not clarified in the question which geometrical shape is formed by the points R S And T ,and W,X and Y .
1. Considering R S and T and W,X,Y to be collinear points . ,
and it is given that , RS T = W X Y ( are equal line segments).
Then
Corresponding part of , RT will be W Y.
2. If these points ,that is R,S,T and W,X,and Y are non collinear , they will form a triangle.
As Given : Δ RST =≅ ΔWXY
If triangle are congruent then their corresponding sides and corresponding angles are equal.
So, Corresponding part of RT will be WY.
