A sequence is an ordered list of numbers whereas a series is the sum of the list of numbers.
Answer:
x ⠀⠀200⠀⠀ ⠀500
y⠀⠀⠀ 11⠀⠀⠀⠀⠀a
As x directly varies with y
200 × a = 500 × 11
a = 5/2 × 11 = 27.5
Answer:
see picture and explanation.
Step-by-step explanation:
First I would find the radius, which is usually half of the diameter. half of 6 is 3. the rest you can see in the picture.
the total area is 188.5 meters squared.
A scientist needs 60 liters of a 60% acid solution. He currently has a 40% solution and a 70% solution. How many liters of each does he need to make the needed 60 liters of 60% acid solution?
----------------
Equation:
acid + acid = acid
----------------------
0.40x + 0.70(60-x) = 0.60*60
-----
40x + 70*60 - 70x = 60*60
-----
-30x = -10*60
x = 20 liters
----
Gabe needs 20 liters of the 40% solution.
He also needs 40 liters of the 70% solution.

➷ The mean is the average
average: all the numbers added together / numbers of numbers.
6+8+8+10+13+16+21+26 = 108
Divide by the number of numbers: 8
108/8=13.5
Final answer:
13.5
