Answer:
12 per 1,000 / year would be population growth
Step-by-step explanation:
To know the population growth it is important to know what it contributes to its growth and that it decreases it.
Birth rate ==> increases growth
Death rate ==> decreases growth
Immigration rate ==> increases growth
Emigration rate ==> decreases growth
Now it only remains to add those that increase growth and subtract those that decrease, like this:
14 per 1,000 / year - 6 per 1,000 / year + 5 per 1,000 / year - 1 per 1,000 / year = 12 per 1,000 / year
12 per 1,000 / year would be population growth
We can model this situation.
Raina received a total of 83 calls
First evening she received 7 more than the third so let x = third and since we know she received 7 more we know to add 7 to the third so (x + 7)
Second evening she received 2 times as many as the third so 2 time third, which x is the third so (2 times x) or we could say 2x
Third evening = x
So now lets solve for x and then we can find how many she received each evening.
Our Model: (x + 7) + 2x + x = 83
(x + 7) + 2x + x = 83
x + 7 + 2x + x = 83
x + 2x + x + 7 = 83
4x + 7 = 83
4x + 7 - 7 = 83 -7
4x = 76
4x / 4 = 76 / 4
x = 19
First evening:
19 + 7 = 26 calls
Second evening
2 times 19 = 38
Third evening
19
Check our answer:
26 + 38 + 19 = 83
Answer:
2826 inches^2
Step-by-step explanation:
The general formula for the total surface area of a regular pyramid is
T.S.A.=12pl+B
Where p represents the perimeter of the base, l the slant height and B the area of the base.
The perimeter of the base is.
p=2L+2W
P=2*10+2*9
P=20+18
P= 38 inches
The area of the base is.
B=10*9
B=90in^2
T.S.A.=12(38)(6)+90
T.S.A=2736+90
T.S.A=2826 inches^2
Hence the paper needed is 2826 inches^2
Answer:
$7.96
Step-by-step explanation:
The equation 9.95/5=x would give you the price of one pound of grapes.
So, now that you have x, you would find out how much it costs if you bought 4 pounds.
4*x=7.96
(x = 1.99)
Answer:
A)The slope of the graph is 1
B) The table is 3
C) The equation is 1/2
D) The table
Step-by-step explanation:
y2-y1/x2-x1=the slope
Pick two undefined points {such as 5,0 and 0,-5)
5-0/0+5=1
The slope is 1.
~~~~~~~~~~
Same equation of slope, you just have to find two points (I chose 2,2 and 4,3
The slope of the equation y=0.5x+1 is 1/2 or 0.5
~~~~~~~~~~
You choose two points (I chose 2,9 and 1,6)
Slope equation
9-6/2-1=3/1=3
Slope is 3
~~~~~~~~~~~
The greatest change is in the table. You know this because it has the greatest slope and if you draw it out on a graph, it has the most significant change.
Good luck!
