Answer:
a) 32100 millimeters
c) 3,210 centimeters
d)3.21 decameters
Step-by-step explanation:
To find which measurements are equal 321 decimeters, we will follow the steps below:
<u>changing 321 decimeters to millimeters</u>
let x be 321 decimeters in millimeters
1 decimeter = 100 millimeters
321 decimeters = x
cross - multiply
x = 321× 100
x = 32100 millimeters
hence, 321 decimeters = 32100 millimeters
<u>converting 321 decimeters to centimeters</u>
let y be 321 decimeters in centimeters
1 decimeters = 10 centimeters
321 decimeters = y
cross-multiply
y = 321× 10
y = 3210 centimeters
Thus, 321 decimeters = 3210 centimeters
<u>converting decimeter to decameters</u>
let z represent 321 decimeters in decameters
1 decameter = 100 decimeter
z = 321 decimeter
cross-multiply
100 z = 321
divide both-side by 100
100z/100 = 321/100
z=3.21 decameters
therefore, 321 decimeters = 3.21 decameters
Answer:
15i and 4i
Step-by-step explanation:
i is an imaginary number also shown as
.
Since we have 
, thats 15* . Substitute for i and we get 15*i or 15i.
We do the same for 
. This is 4* or 4*i or 4i.
An easy way to do this is to take the negative inside the square root like 
, take the absolute value -6 absolute value=6 and times it by i. So now it becomes 6i
Answer: y should be in the interval (0.4, 4)
Explanation:
The binomial 5y - 7 is in the interval (-5, 13) if and only if
-5 < 5y - 7 < 13
Solving the inequalities in this form is the same as solving equation. So, we add all sides of the inequalities by 7 so that
2 < 5y < 20
Then, we divide both sides by 5 to get the following inequalities
0.4 < y < 4
Hence y should be in the open interval (0.4, 4).
