B about 20-30 m2 (count the number of squares where more than half the area is green
Answer:6.37%
Step-by-step explanation:
Currently, the total number of computer programmers employed in a certain country is approximately
455000
By next decade, this number is expected to increase to 484000
To determine the increase in the number of computer programmers in a decade, we will subtract the current number of computer programmers from the expected number of computer programmers in the next decade. It becomes
484000 - 455000 = 29000
To determine the percent increase, we will divide the increase in computer programmers by the number of computer programmers currently and multiply by 100. It becomes
29000/455000 × 100
= 6.37%

Answer:</h3>
System
Solution
- p = m = 5 — 5 lb peanuts and 5 lb mixture
<h3>
Step-by-step explanation:</h3>
(a) Generally, the equations of interest are one that models the total amount of mixture, and one that models the amount of one of the constituents (or the ratio of constituents). Here, there are two constituents and we are given the desired ratio, so three different equations are possible describing the constituents of the mix.
For the total amount of mix:
... p + m = 10
For the quantity of peanuts in the mix:
... p + 0.2m = 0.6·10
For the quantity of almonds in the mix:
... 0.8m = 0.4·10
For the ratio of peanuts to almonds:
... (p +0.2m)/(0.8m) = 0.60/0.40
Any two (2) of these four (4) equations will serve as a system of equations that can be used to solve for the desired quantities. I like the third one because it is a "one-step" equation.
So, your system of equations could be ...
___
(b) Dividing the second equation by 0.8 gives
... m = 5
Using the first equation to find p, we have ...
... p + 5 = 10
... p = 5
5 lb of peanuts and 5 lb of mixture are required.

Answer:
Every day, 43% percent of people are added from the total number of people who receive the email
Step-by-step explanation:
we know that
The equation of a exponential growth function is given by
where
P(t) is the total number of people who receive the email
t is the time in days
a is the initial value
r is the rate of change
we have
so
---> initial number of people who receive the email
solve for r
Convert to percentage
so
The daily percent change in the number of people who receive the email. every day is 43%
therefore
Every day, 43% percent of people are added from the total number of people who receive the email
