Answer:
Approximately 18.7% people lived without clean drinking water.
Step-by-step explanation:
Given:
Total Number of people living in the world =
Number of people didn't have access to clean drinking water =
We need to find the approximately what percent of them lived without clean drinking water.
Solution:
Now we can say that;
To find the percent of people lived without clean drinking water can be calculated by Number of people didn't have access to clean drinking water divided by Total Number of people living in the world multiplied by 100.
framing in equation form we get;
percent of people lived without clean drinking water =
Hence Approximately 18.7% people lived without clean drinking water.
we have the sequence
-108, -91,-74,-57,...
we have
a1=-108
a2=-91
a3=-74
a4=-57
step 1
Find the common difference d
a2-a1=-91-(-108)=17
a3-a2=-74-(-91)=17
so
d=17
step 2
thw general equation for an arithmetic sequence is equal to
an=a1+d(n-1)
we have
d=17
a1=-108
substitute
an=-108+17(n-1)
an=-108+17n-17
an=-125+17n
therefore
the answer is an=-125+17n
Answer:
403
Step-by-step explanation:
Yes it is, only that the one on the right is the diminished version of the one on the left. if you look closely you will see that they have divided the measurements by 2 on each side, such as: 10: 2 = 5 6: 2 = 3 and the x is probably 14: 2 which is 7
Answer:
The equation of the line is y = 2x - 6
Step-by-step explanation:
To find the equation of this line, we first need to find the slope. To find a slope you need two ordered pairs, which you have here. The first is (5, 4) and the second is (3, 0) - which is the x-intercept of 3. Now that we have this, we can plug into the slope equation.
m(slope) = (y2 - y1)/(x2 - x1)
m = (4 - 0)/(5 - 3)
m = 4/2
m = 2
Now that we have the slope, we can use that and either point in point-slope form. Once we do that, we solve for y to get the equation.
y - y1 = m(x - x1)
y - 4 = 2(x - 5)
y - 4 = 2x - 10
y = 2x - 6
