40% because 32/80 is 0.4 move two decimal points
Since there is no condition whatsoever for this arrangement, I can consider the 2 digits and the 5 letters as 7 different objects.
Total permutation (with no repetition):
7 chosen among 7 , that is 7 ! = 5040 arrangements
Total permutation (WITH REPERTITION):
7⁷ = 823 543
We have been given image of circle that passes through point . We are asked to find the radius of the circle.
First of all, we will find the center of the circle.
We can see that center of circle is at point .
Now we will use equation of circle to find radius.
, where, point (h,k) represents center of circle and r represents radius of circle.
Now we will substitute the coordinates of point and coordinates of center and solve for r as:
Switch sides:
Now we will take positive square root on both sides:
Therefore, radius of circle will be and center is at point .
Answer:
x=2
Step-by-step explanation:
(5-2i)-(x+4i)=7-6i
put like expressions together first:
(-4i-2i)+5+x=7-6i
-6i+5+x=7-6i
6i-6i+5+x=7-6i+6i
5+x=7
5-5+x=7-5
x=2
Answer:
re order is 90 bottles
Step-by-step explanation:
given data
shampoo in stock = 50 bottles
reserve = 35
stock record = 4 week
delivery = 3 week
average sale = 15 / week
to find out
what should be re ordered
solution
according to question we know that total week for order is
total week for order = 4 + 3 = 7 week
so total sale in 7 week is = 7 × average sale
total sale in 7 week = 7 × 15 = 105 bottles
and
he need more bottle = total sale - in stock
need bottle = 105 - 50
need bottle = 55
so order = need bottle + reserved bottle
order = 55 + 35
order = 90 bottles
so re order is 90 bottles
