Answer:
8.652
Step-by-step explanation:
Ignore the points and multiply, then you see that 4.12 has two decimal places and that 2.1 has one decimal place, when you add them there is three decimal places.
412 x 21 = 8652
4.12 x 2.1 = 8.652
Pls mark me as brainliest!!!!
Using the degree of freedom rule, we can solve three unknown variables if and only if the number of independent equations is equal to 3. Thus the number of equations should be equal to the number of variables. We can use substitution to find x.
<span>g(x) = 2k(x) (1)
</span><span>g(x)=2x^+3x+10 (2)
k(x)=2x+16 (3)
we substitute 2 to 1 and also 3 to 1. The resulting function hence becomes:
</span>2x^+3x+10 = 2 * (2x +16)
Simplifying the equation on the right.
2x^+3x+10 = 4x +32
we group then the like terms on one side. That is,
2x^+3x - 4x+10 -32 = 0
2x^2 - x - 22 = 0
The factors using the quadratic equation are
x1 ==1/4+1/4√<span>177
</span>x2 ==1/4-1/4√177
a = 4 first term, r = ?, T10 = 100.
Tn = ar^n - 1 formula for g.p
T10 = 4r^ 10 - 1
100 = 4r^9
Divide both side by 4
100/4 = 4/4r^9
25 = r^9 take the 9th root of both side
9√25 = 9√r^9
r = 9√25
To find the nth term
Since Tn = ar^n - 1
Answer:
97
Step-by-step explanation:
Sorry for messy working out
45% divided by 6 people will equal percentage per person (7.5% each). So, 100% divided by 7.5% will equal how many people (answer is 13.3333333333, but you can't have one third of a person, so round to 13). Answer = 13 people
