Answer:
Actual area = 21600 Sq.miles
Step-by-step explanation:
We are given;
length; L = 4 inches
Width; W = 6 inches
The scale of the map; 1 inch for every 30 miles i.e. 1 : 30
Since the scale is 1:30, let's find the find the actual dimensions and then the actual area
For the Length,
Since 1 inch represents 30 miles,
Then, 4 inches = (4 × 30)/1 = 120 miles
For the width;
Since 1 inch represents 30 miles,
Then,6 inches = (6 × 30)/1 = 180 miles
Therefore, the actual dimensions are 120 miles and 180 miles
Now, formula for area of rectangle = length × width
Thus;
Actual area = 120 × 180
Actual area = 21600 Sq.miles
Answer:
(1.5)x
Step-by-step explanation:
90 minutes = 1.5 hours therefore
if car travels x miles in 1 hour
then the care has to travel (1.5)x miles in 90 minutes
Answer:
24
Step-by-step explanation:
14/2=7
25^2-7^2=576
sqrt576=24
Let's find the least possibilities:
First number: 6
Second number: 8
Third number: 10
6 + 8 + 10 = 24
Now we can see that we are still missing 31 - 24 = 7.
7 can be gained by adding 3 and 4, so:
First number: 6 + 3 = 9
Second number: 8 + 4 = 12
Third number: 10
9 + 12 + 10 = 31
Answer:
(a) 
Multiplicative inverse of w will be 
(B) As w is same as the product of 
So there multiplicative inverse will also be same
Step-by-step explanation:
We have given two complex numbers
and 
(a) First we have to find 
So 
As we know that 
So
Multiplicative inverse :
It is that number when multiply with the number which we have have to find the multiplicative inverse gives result as 1
So multiplicative inverse of w will be
Because when we multiply 
with it gives result as 1
(b) As w is same as the product of
So there multiplicative inverse will also be same
