schepotkina [342]

Answer:

Town B will eventually overtake Town A

in 1990 Town B will have a larger population

Step-by-step explanation:

To work out how big town A will be in 1990 you need to do 200 + (200x40) because you add 40 years worth of increased population onto the starting population

To work out how big town B will be in 1990 you need to use the equation 200 X 1.1^40 because to work out plus 10 percent you need to do 1.1 and do it to the power of 40 for how many years

in 1990 town a will have a population of 8200 and town B will have a population of 9051.85

MIDDLE SCHOOL MATH- 4 QUESTIONS

Contact [7]

Answer:

( I am assuming that these are all fractions)

1. 14 $\frac{4}{7}$

2. 8

3. $\frac{4}{15}$

4. 5 $\frac{8}{11}$

Step-by-step explanation:

1. First you have to convert 15 into a fraction but it must have the same denominator causing the equation to look like 105/7 - 3/7= 102/7. But you cannot just leave the fraction like that it must be simplified 14 $\frac{4}{7}$

2. Three-fifths of an hour is 36 minutes. You would next multiply 5 by 60 which would the hours into minutes 5 x 60 = 300. You would then divide 300 by 36 which would give you 8.3333333333, which I just simplified it to 8

3. In order for you to multiply a fraction you would first multiply the top then the bottom. 12 x 6= 72, 15 x 18= 270. The fraction would look like 72/270 which is simplified to $\frac{4}{15}$ .

4. First I changed the fractions into improper fractions causing the fraction to look like 36/8 x 14/11 (I got these answers by 8 by 4 then adding 4, then for the next fraction I multiplied 11 by 1 then added 3.) 36 x 14= 1224, 11 x 8= 88 the fraction would look like 1,224/88 you would simplify to 5 $\frac{8}{11}$

Hope this helps

Please tell me if I made any mistakes I enjoy learning from them.

For the answer to the question above, to solve these questions, use this formula: X3= F(X1-X2) Y3= F(Y1-Y2)
Where X3 is the X value in the coordinate your solving for, F is the fraction,
X1 is the first X and X
2 is the second X Plug in your numbers to fit this: X3= 1/4 x (0--2) Y3= 1/4 x (4- -3) By solving you get: (-.5, 1.75)
