Answer:
A circular pizza box logo has a sector with a central angle of 40 degrees and a diameter of 25 inches. Find the area of this sector.
-------
r = d/2 = 12.5 inches
Step-by-step explanation:
Step-by-step explanation:
8) Consider,
Multiplying And Dividing By 1-sinx
We know (a+b)(a-b)=a²-b²
We know that sin²x+cos²x=1
cos²x=1-sin²x,
uisng this we get,
We know that 1/cosx=secx and sinx/cosx=tanx
Using this we get,
Hence Proved
The incorrect claim is A. He is incorrect. The path will have an area of (4)(40)=160 sq ft. The yard has an area of 600 sq ft. The area of the lawn will be the difference of the yard and path, so it is 440 sq ft.
<h3>What is an Area?</h3>
This refers to the quantity used in mathematics to show the extent of a two-dimensional region, shape, or planar lamina, in the plane.
Hence, because Roy wants to make a path from one corner of his yard to the other, he makes an incorrect claim about the area of the yard and the lawn, and option A is the correct answer.

Answer: the expression is c/2 - 4.5
Step-by-step explanation:
Let c represent the total number of coins that he has initially.
He gives his sister 9 coins. This means that the remaining number of coins that he has is c - 9
He then splits the remaining coins into 2 equal stacks. Therefore, the expression that represents the number of coins in each stack would be
(c - 9)/2
Simplifying further, it becomes
c/2 - 9/2
c/2 - 4.5
The <em>initial</em> investment of Calvin must be increased by a factor of 115.927 % to equal Marquez's investment at any time. (Correct choice: D)
<h3>How to determine the investment needed by Calvin to equal Marquez's investment at any time</h3>
In this question we must apply the concept of compound interest to derive the <em>initial</em> investment to be done by Calvin. According to the statement, Calvin invests money five years later than Marquez.
To determine the initial investment to be deposited by Calvin such that his investment equals Marquez's investment at any time we resort to the following expression:
(1)
Then, we simplify the required <em>initial</em> investment:
And the increase factor is:
The <em>initial</em> investment of Calvin must be increased by a factor of 115.927 % to equal Marquez's investment at any time. (Correct choice: D)
