Answer:
its 8
Step-by-step explanation:
use ratio solution ..
2 shampoo : 9 water
8 shampoo : 36 water
9x4 = 36
same goes too shampoo.. it needs to be multiplied with 4 as to get 36 water u multiplied 9 with 4
Ok so to find the ratio just do 12/16 = 3/4. that's your common ratio.
The formula for sum of infinite :
a / (1 - r)
a is the first term and r is the ratio
which is
16 / (1 - (3/4))
which is
16 / (1/4)
16 * 4
which is 64

Step-by-step explanation:
there ar 16 ticks on a scale, the pointer is on 12, meaning it is 12/16, whihc is answer b
Answer:
Step-by-step explanation:
The LCD here is 10.
Multiplying numerator and denominator of (4*10^2) by 10 results in:
40*10^3
-------------
10
and rewriting (2x10^-1) with positive exponent in the denominator results in:
2
---------
10
So, before simplification, this difference comes out to be:
40000 - 2 39998 19999
----------------- = ---------------- or ------------
10 10 5
Answer:
x₁ = -4
x₂ = 3
Step-by-step explanation:
x²+ x + 12 = 0
x = {-1±√((1²)-(4*1*-12))} / (2*1)
x = {-1±√(1+48)} / 2
x = {-1±√49} / 2
x = {-1±7} / 2
x₁ = {-1-7} / 2 = -8/2 = -4
x₂ = {-1+7} / 2 = 6/2 = 3
Check:
x₁
-4² + (-4) - 12 = 0
16 - 4 - 12 = 0
x₂
3² + 3 - 12 = 0
9 + 3 - 12 = 0
