Answer:
Step-by-step explanation:
supplementary angles sum = 180
Measurement of Measure of its
an angle Supplement
80° 180 - 80 = 100°
25° 180 - 25 = 155°
119° 180 - 119 = 61°
x 180 - x
OK.... here we go....
The width is 8 less than the length, so that means: w = L - 8.
So, since the area of a rectangle is: A = L x W ...
Therefore, 48 = L(L - 8)...
48 = L^2 - 8L...
continuing from there .... you get width = 4 and length = 12
48 = 4 x 12 (and notice that the width is 8 less than the length)
I believe the volume of the shape is 210mm. the formula is v=lwh. so you multiply all the numbers to get 210. hope that helped!
Answer:
The surface area of the prism is 72 square units.
Step-by-step explanation:
In order to calculate the surface area of the prism we must calculate the area of each face of the prism. To better visualize it we can look at the picture below. We must calculate the area of every face in the picture, so we have:
surface area = 2*[(1/2)*3*4] + 3*5 + 4*5 + 5*5
surface area = 12 + 15 + 20 + 25
surface area = 72 square units
Answer:
About 28,671,342 people
Step-by-step explanation:
This is compound growth problem. This goes by the formula:

Where
F is the future amount (in 3 years)
P is the present amount (28.5 million)
r is the rate of growth (0.4% = 0.4/100 = 0.004)
t is the time in years (3 years)
We first, need to find the rate of growth annually. It is given 0.4% every 2 years, so in 1 year that would be:
0.4%/2 = 0.2% = 0.002
Now, we put the information into formula and solve:

So, around 28,671,342 people will be infected in 3 years.
