Answer:
235
Step-by-step explanation:
The population equation is given as P= 2.726x + 126.189
-To find the number of years since 1980, we subtract the start year from the current year(2020):
X=2020-1980=40
We substitute the x value in the population equation to find the current population:
P=2.76x+126.189 but x=40
P=2.76(40)+126.189=235.229
Rounding off then the population in the current year is 235
9514 1404 393
Answer:
Step-by-step explanation:
The turning point (maximum or minimum) of quadratic function ...
f(x) = ax² +bx +c
is at x = -b/(2a).
Here, this means the maximum profit will be had when the number of widgets produced weekly is ...
x = -88/(2(-2)) = 22
The profit at that level of production is ...
P(22) = (-2·22 +88)(22) -384 = 44(22) -384 = 968 -384 = 584 . . . hundreds
22 widgets must be produced weekly for the maximum weekly profit of $58,400.
Answer:
$112.17
164.95 * 0.32 = 52.784
164.95 - 52. 784 = 112.166
112.166 = 112.17
The answer is A 24$ because 30x40 is 1200 and 1200x 0.02 is 24
Answer:
The number of each kind of apartment in the building is 130 .
Step-by-step explanation:
Given as :
The total number of floor in a building = 15
The number of apartment on each floor = 26
So, The total number of apartment = 26 × 15 = 390
The number of kinds of apartment in the building is 3 , i.e 1-bedroom , 2-bedroom , 3-bedroom
Let The number of each kind of apartment in building = x
So, According to question
The number of each kind of building = 
or, x = 
∴ x = 130
Hence The number of each kind of apartment in the building is 130 . Answer
