Since only 30% of the teachers taught for one year, the remaining percentage of the teachers had taught for more than a year, or 70%.
70%=0.7
80(0.7)=56
56 teachers had taught for more than a year.

Given f(x) = -5x + 1. What is f(-3)?
babunello [35]

Answer:

f(-3) =16

Step-by-step explanation:

f(x) = -5x + 1

f(-3) means let x=-3

Substituting x=-3 into the equation

f(-3) = -5 (-3) +1

Multiplying -5 and -3

f(-3) = 15+1

f(-3) =16

The population of a local species of flies can be found using an infinite geometric series where a1 = 940 and the common ratio i
alex41 [277]

A. Sigma notation

The formula for finding the nth value of the geometric series is given as:

an = a1 * r^n

Where,

an = nth value of the series

<span>a1 = 1st value in the geometric series = 940</span>

r = common ratio = 1/5

n = nth order

The sigma notation for the sum of this infinite geometric series is therefore,

                     (see attached photo)

B. Sum of the infinite geometric series

The formula for calculating the sum of an infinite geometric series is given as:

<span>S = a1  / (1 – r)</span>

Substituting the given values:

S = 940 / (1 – 1/5)

<span>S = 1,175</span>

Which expression represents the algebraic phrase "eleven less than seven times a number"? 11x - 7 7 x minus 11 11 + 7x 11 minus
SIZIF [17.4K]

Answer:

7x minus 11

Step-by-step explanation:

7x would be 7 times whatever x is. then you subtract 11 from 7x. the reason you’re subracting 11 from 7x is because 11 has to be less than 7x (i understand negatives, but we’re not using that in this problem.)
