Town B will have more population in 1990.
Given that, in 1950 town A had a population of 200 people and the population increased by 200 people each year. In 1950, Town B had a population of 200 people and the population increased by 10% each year.
We need to find which town will have more people in 1990.
Town A = 1990 - 1950
= 40 years
Therefore, in 40 years it will have = 40 × 200 = 8000 population.
Town B = It is increasing by 10% each year,
so in 40 years,
P = 200(1+0.1)⁴⁰
P = 9051
Since the population of town B is greater than the population of town A.
Hence town B will have more population in 1990.

A pump releases water at a rate of 10 gallons every 45 days.
What is the unit rate in gallons per week?
Enter your answer as a mixed number in simplest form in the box.
gal/week
Answer:
6 miles
Step-by-step explanation:
6 times 4 = 24
Answer:
10 mph, 1 5/9
Step-by-step explanation:
Set up a ratio:
4/24 = x/60
Cross multiply and solve
4 * 60 = 24x
240 = 24x
10 = x, 10 mph
10 gallons every 45 days is ever 6 3/7 weeks
10 divided by 6 3/7
10 divided by 45/7=
10 times 7/45 = 70/45, = 14/9 = 1 5/9

Step-by-step explanation:
Answer:
Firstly, we know 3^3 ÷ 3^-4 =2187. So, we got to check the value for each expression given below.
3x 3^6 = 2187
3^7 ÷ 3^0 = 2187
3^-3 ÷ 3^4 = 1/2187 (odd one out)
3^3 x 3^4 = 2187
Answer is 3^-3 ÷ 3^4

anyway, we need to make 2/3 and 3/4 comparable.
for this we need to bring both fractions to a common denominator, which is usually the smallest common multiple of the denominators.
yes, 12 is the smallest number that can be divided by 3 and by 4 without remainder.
to transform a fraction too another denominator, we need to multiply it by a fraction a/a, which has the value 1, of course (so we don't change the value of the original fraction), but changes the denominator to the desired number.
what do I multiply with 4 to get 12 ? 3.
so, I multiply 3/4 by 3/3 = 9/12.
what do I multiply with 3 to get 12 ? 4.
so, I multiply 2/3 by 4/4 = 8/12.
now we can compare and calculate :
out of the total of 9/12kg 8/12kg were used.
that means
1/12kg of carrots are left.

this is a strange question, as watermelons, bananas and melons are very differently sized. so, for example 1/2 watermelon and 1/2 banana are very different quantities.
so, what does e.g. 1 fruit mean ?
or if we understand the fractions as shares of the overall smoothie, then we have too much. 4/6 (watermelon) + 2/6 (melon) = 6/6 = 1 (whole smoothie).
so, what to do with the banana ?
this question does not make any sense at all.
but if it is just to add fractions, we can do that :
4/6 + 1/2 + 2/6
as mentioned above, 4/6 + 2/6 = 6/6 = 1
1 + 1/2 = 2/2 + 1/2 = 3/2 = 1.5 or 1 1/2
so there is 1 1/2 fruit in the smoothie (whatever that means).
3.
1 1/2 + 2 1/2 = 2/2 + 1/2 + 4/2 + 1/2 = 8/2 = 4

–3 times the first equation and 5 times the second equation
3 times the first equation and 5 times the second equation
Answer:
Its the second one x=5
Step-by-step explanation:
I took the test.
Answer:
-10 times the first equation and 3 times the second equation
Step-by-step explanation:
Multiply the first equation by 10 and the second equation by -3:
1. 1/5 x + 3/4 y = 9
x-10 ⇒ -2x - 15/2 y = -90
2. 2/3 x - 5/6 y = 8
x3 ⇒ 2x - 5/2 y = 24
Add the equations together:
-2x - 15/2 y = -90
+ 2x - 5/2 y = 24
-------------------------
0x - 10y = -66

The image of the point (2, -9) under a translation is (4, -14). Find the coordinates of the image of the point (5,6) under the same translation.
Answer:
(7,1)
Step-by-step explanation:
I just did it the same way the other one went, but tbh don't just listen to me I'm not that smart I just believe it's the answer from my math.
Answer:
(7, 1)
Step-by-step explanation:
translation = [tex]\left[\begin{array}{c}2\\-5\end{array}\right][/tex]
(2 units to the right and 5 units down)
Therefore, x coordinate = 5 + 2 = 7
y coordinate = 6 - 5 = 1
So translated point is (7, 1)
Sari is factoring the polynomial 2x2+5x+3. If one factor is (x+1), what is the other factor?
Answer:
(2x + 3)
Step-by-step explanation:

Answer:
x = √55
Step-by-step explanation:
using Pythagoras Theorem:
x² + 3² = 8²
x² = 64 - 9
x² = 55
x = √55 ..........this is your answer in radical form.
x = 7.416
Answer:
x = √55 = 7.4162
Step-by-step explanation:
The Pythagorean Theorem states that a^2 + b^2 = c^2
so 3^2 + x^2 = 8^2
x^2 = 64 - 9 = 55
x = √55 = 7.4162

A company is planning to set up a new manufacturing plant for giant inflatable beach balls and believe the costs follow a linear model. The cost analysts estimate the cost of producing 10,000 beach balls to be $587,500 and the cost of producing 50,000 beach balls to be $717,500
The cost(y) of producing x number of balls is given by the linear model y = 3.25x + 685000
Linear equation
A linear equation is in the form:
y = mx + b
where y, x are variables, m is the rate of change (slope) and b is the y intercept.
Let y represent the cost of producing x number of beach balls.
Using the point (10000, 587500) and (50000, 717500):
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-717500=\frac{717500-587500}{50000-10000} (x-10000)\\\\y=3.25x+685000[/tex]
The cost(y) of producing x number of balls is given by the linear model y = 3.25x + 685000

Answer:
(-2,-2)
Step-by-step explanation:
Step: Substitute 3x+4 for y in y=−x−4:
y=−x−4
3x+4=−x−4
3x+4+x=−x−4+x (Add x to both sides)
4x+4=−4
4x+4+−4=−4+−4 (Add -4 to both sides)
4x=−8
4x/4=−8/4(Divide both sides by 4)
x=−2
Step: Substitute −2 for x in y=3x+4:
y=3x+4
y=(3)(−2)+4
y=−2(Simplify both sides of the equation)
Find the distance between (11, 7), (16, 6)
Answer:
The answer is √26
Step-by-step explanation:
Given;x₁ = 11; x₂ = 16y₁ = 7; y₂ = 6Let the point be A and B i.e.,
A = (11, 7)
B = (16, 6)
Now, The distance between A and B
AB = √(x₂ – x₁)² + (y₂ – y₁)²
AB = √(16 – 11)² + (6 – 7)²
AB = √(5)² + (-1)²
AB = √25 + 1
AB = √26
Thus, The distance between A and B is √26
