Answer:
33.15 square inches.
Step-by-step explanation:
Given:
Length of the minute hand is 11.25' from the center of the clock to the tip of the hand.
<u>Question asked:</u>
What is the area swept out by the minute hand as it moves 5 minutes of time?
Solution:
<u><em>As length of the minute hand is '11.25' from the center of the clock to the tip of the hand means radius of the circle, r = 11.25 inches.</em></u>
First of all we will find area of circle swept by the minutes hand,
When minute hand moves 60 minutes, it makes one circle of area 397.77 square inches.
By using<u> unitary method</u>, we will calculate area swept by minute hand in 5 minutes:-
In 60 minutes, area swept = 397.77 square inches
In 1 minute, area swept = 
In 5 minutes, area swept = 
Thus, the area swept out by the minute hand is 33.15 square inches when it moves 5 minutes.
Answer:
fx
Step-by-step explanation:
Answer:
Draw a dashed line to represent the graph of 
and shade the portion below the line for positive values of x and y
Step-by-step explanation:
Let
x------> the number of nickels in the box
y------> the number of dimes in the box
we know that
Multiply by 
both sides
------> inequality that represent the situation
The solution of the inequality is the triangular shaded area below the dashed line
see the attached figure
therefore
The statement which best describes the steps to graph the solution to the inequality in x and y is
Draw a dashed line to represent the graph of and shade the portion below the line for positive values of x and y
Answer:
8
Step-by-step explanation:
Y×2+3=19
19-3=16
16÷2=8
You subtract the 3 first to get what the number was when doubled. After getting that number you would divide it by 2 to get the number that you thought of.
Answer:The purpose of scientific notation is for scientists to write very large, or very small, numbers with ease.
Calculating scientific notation for a positive integer is simple, as it always follows this notation:
a x 10b
Follow the steps below to see how 12,500 is written in scientific notation.
Step 1
To find a, take the number and move a decimal place to the right one position.
Original Number: 12,500
New Number: 1.2500
Step 2
Now, to find b, count how many places to the right of the decimal.
New Number: 1 . 2 5 0 0
Decimal Count: 1 2 3 4
There are 4 places to the right of the decimal place.
Step 3
Building upon what we know above, we can now reconstruct the number into scientific notation.
Remember, the notation is: a x 10b
a = 1.25 (Please notice any zeroes on the end have been removed)
b = 4
Now the whole thing:
1.25 x 104
Step 4
Check your work:
104 = 10,000 x 1.25 = 12,500
