Between 2000 and 2014, the number of twin births in a certain country increased by 15%, to approximately 133975. About how many twin births were there in 2000?
Answers
An increase by 15% means 15 added to per cent (per = each; cent=100).
If the population was 100 in the year 2000 then it would be 115 in the year 2014. (adding 15 to 100)
The population was 116500 in the year 2000 and it increased to 133975 in the year 2014.
Let the population be x in the year 2000.
Using ratio and proportion
Year 2000 : Year 2014
100 : 115
x : 133975
Applying cross product rule
x × 115= 100× 133975
x= 100× 133975/115
x= 116500
The population was 116500 in the year 2000 and it increased to 133975 in the year 2014.
Answer:
116500
Step-by-step explanation:
We are looking for the number of twin births in 2000.
Let the number of twin births in 2000 be x.
The number of twin births in 2000 is 100% of the number of births in 2000 since 100% of something is the entire thing.
The number of twin births went up 15% from 2000 to 2014, so in 2014, the number of twin births was 100% of the number of twin births plus another 15% of the number of twin births.
100% + 15% = 115%
The number of twin births in 2014 was 115% of x.
The number of twin births in 2014 was 133975.
115% of x = 133975
115% * x = 133975
1.15x = 133975
x = 133975/1.15
x = 116500
The number of twin births in 2000 was 116500.

first of all you must find out how many vases he makes per day;
24 ÷ 8 = 3 vases per day
So if he makes 3 vases per day now to find how much time he takes per vase you must divide the number of hours he works per day by the number of vases he makes per day;
6 hours ÷ 3 vases =
6 ÷ 3 = 2
so your final answer would be: 2 hours per vase
It takes 2 hours to make 1 vase~

Triangles ABC and DEF are similar, which means corresponding sides are proportional to one another. Here, side AB corresponds to DE, BC to EF, and AC to DF.
We know the length of AB and AC, and we can figure out the length of BC using the Pythagorean theorem:
Sides BC and EF correspond to one another, and EF is 2 times longer than BC. This means DF is 2 times longer than 17, so that .
