Well, a ratio can be a fraction for example in the fridge there are 5 chocolate icecream bars and 3 strawberry. this would be expressed as 5/3 or 5:3 or 5 to 3
Answer:
The total earned after 30 days is 465000.
Step-by-step explanation:
The amount of money that I'll recieve can be modelled as a arithmetic sequence in which the next element is related to the prior by a sum of a rate "q". This sequence can be seen below:
{1000, 2000, 3000, ...}
Where q = 1000. In order sum all the "n" terms on a sequence of this kind we can use the following formula:
Sn = (n/2)*(a1 + an)
And to find the term an, we can use the formula:
an = a0 + (n-1)*r
Where n is the position of the number we want to calculate, in this case 30, a0 is the first number on the sequence and r is the rate between consecutive numbers. So the 30th term is:
a30 = 1000 + (30 -1)*1000
a30 = 1000 + 29*1000
a30 = 1000 + 29000 = 30000
And the total obtained is:
s30 = (30/2)*(1000 + 30000) = (30/2)*(31000)
s30 = 930000/2 = 465000
The total earned after 30 days is 465000.

Basically times 2,500,000 by 3
Answer:
147 in2
Step-by-step explanation:
(Assuming the height is 4 1/2 inches = 4.5 inches)
We need to calculate the area of all six faces of the prism
Two faces have the sides 8 and 3, which area is 8*3 = 24 in2
two other faces have the sides 8 and 4.5, which area is 8*4.5 = 36 in2
the two last faces have the sides 3 and 4.5, which area is 3*4.5 = 13.5 in2
So, summing up all the areas, we have:
24 + 24 + 36 + 36 + 13.5 + 13.5 = 147 in2
100,000+20,000+200+5 in standard form is 120,205
