The population of each country will become double in 47 years.
Given that,
The population of the Dominican republic is, n = 10.7 million.
The growth rate of the Dominican republic is, p = 1.5 %.
The population of Paraguay is, n' = 6.0 million.
The growth rate of Paraguay is p' = 1.5 %.
The doubling time of population growth depends on the rate of population growth.
Here,
n is the final population and n0 is the initial population and doubling the value in the future, n= 2*n0.
Solving this, we get:
t= ln (2*n0/n0)/(1.5/100) = 47 years.
Thus, we can conclude the population of each country will become double in 47 years.

Two mechanics worked on a car. The first mechanic worked for 20 hours, and the second mechanic worked for 5 hours. Together they charged a total of $1150. What was the rate charged per hour by each mechanic if the sum of the two rates was $95 per hour?
Answer: Let's call the hourly rate of the first mechanic "r1" and the hourly rate of the second mechanic "r2".
We know that the total time they worked is 20 hours + 5 hours = 25 hours.
We also know that the sum of their hourly rates is $95 per hour, so:
r1 + r2 = $95
We can use this information along with the total amount they charged, $1150, to find out how much each mechanic charged. We know that the total amount charged is the product of the number of hours worked and the hourly rate. So we can use the following equation:
(20 hours * r1) + (5 hours * r2) = $1150
Now we can substitute the equation r1 + r2 = $95 into the above equation and solve for r1:
(20 hours * r1) + (5 hours * (95 - r1)) = $1150
20r1 + 475 - 5r1 = 1150
15r1 = 675
r1 = $45/hour
To find out the hourly rate of the second mechanic, we can use the equation r1 + r2 = $95
r2 = $95 - r1
r2 = $95 - $45
r2 = $50/hour
So the first mechanic charges $45 per hour and the second mechanic charges $50 per hour.

Ekaterina’s favorite expression is 4x – 4. Alban’s favorite expression is 8x – 24. What value of x makes these two expressions equal?
Answer:
x = 5
Step-by-step explanation:
You are solving for a x that can, when plugged in, equate both given expressions. To do so, set each given expression equal to each other:
4x - 4 = 8x - 24
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
PEMDAS is the order of operations, and stands for:
Parenthesis
Exponents (& roots)
Multiplications
Divisions
Additions
Subtractions
~
First, subtract 8x and add 4 to both sides of the equation:
4x (-8x) - 4 (+4) = 8x (-8x) - 24 (+4)
4x - 8x = -24 + 4
-4x = -20
Next, divide -4 from both sides of the equation:
(-4x)/-4 = (-20)/-4
x = -20/-4
x = 5
5 is your answer.
Check:
Plug in 5 for x in both given expressions:
4x - 4
4(5) - 4
= 20 - 4
= 16
-
8x - 24
8(5) - 24

Please help, i know you have to use pythagoras and the hypotenuse is 8.44 but i dont know how to get one of the sides
======================================================
Explanation:
Check out the diagram below.
I've defined the following points:
A = center of the circle, and center of the squareB, C, D, and E = vertices of the square that are on the circleF = midpoint of segment CDNow focus on triangle ACF. This is an isosceles right triangle with legs of 0.5x each. The hypotenuse is the radius of the circle. Let R be that unknown radius.
The area of the circle is given to us. It is 56 square cm. Use this to find the value of R.
[tex]A = \pi*(\text{radius})^2\\\\56 = \pi*R^2\\\\R^2 = 56/\pi\\\\R = \sqrt{56/\pi}\\\\R = 4.22200825\\\\[/tex]
This value is approximate. I used the calculator's stored version of pi to get the most accuracy possible.
------------
We now know the hypotenuse of triangle ACF.
Use Pythagoras (aka Pythagorean Theorem) to have the following steps:
[tex]a^2+b^2 = c^2\\\\(0.5\text{x})^2+(0.5\text{x})^2 = 4.22200825^2\\\\0.25\text{x}^2+0.25\text{x}^2 = 17.82535366\\\\0.5\text{x}^2 = 17.82535366\\\\\text{x}^2 = 17.82535366/0.5\\\\\text{x}^2 = 35.65070732\\\\\text{x} = \sqrt{35.65070732}\\\\\text{x} = 5.97082132708726\\\\\text{x} = 5.97\\\\[/tex]
The final answer is 5.97With the exception of 0.5 and 0.25, each decimal value mentioned is approximate.
Keep in mind that rounding to 3 sig figs means that we're rounding to 2 decimal places. The units digit is 1 sig fig, and the 2 decimal places give a total of 1+2 = 3 sig figs.
In short, we're rounding to the nearest hundredth.
--------------------
Check:
x = 5.97 is the square's side length.
It divides in half to get x/2 = 5.97/2 = 2.985 which gives each leg of triangle ACF.
Use a = 2.985 and b = 2.985 in the Pythagorean Theorem to find that c = 4.22142748 approximately. This is the approximate radius of the circle.
Use that radius to find the area of the circle.
A = pi*r^2
A = pi*(4.22142748)^2
A = 55.984594705958
A = 56.0
I'm rounding the area to 3 sig figs to keep consistent with the rounding done to x. We arrive at the circle area of 56 square cm, which helps confirm the answer is correct.

A percentage is a fraction or ratio in which the whole value is always 100. For instance, Sam would have received 30 out of a possible 100 points if he had received 30% on his math test. It is expressed as 30/100 in fractional form and 30:100 in ratio form.
48 = 100% of 48
12 = 25% of 48
60 = 125% of 48

hat is the probability that an ace appears at the 9th place, and a queen appears at the 10th place in the deck?
The probability that an ace appears at the 9th place, and a queen appears at the 10th place in the deck is 1/221.
What is Probability?The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.
Given:
The probability that an ace appears at the 9th place, and a queen appears at the 10th place in the deck can be calculated as:
There is a total of 52 cards in a deck and 4 aces and 4 queen cards.
So, the probability is
4/52 * 4/51 = 1/221

How do you solve ratio word problems in 7th grade?
A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0. A proportion is an equation in which two ratios are set equal to each other
What is an equivalent ratios?
A ratio compares two quantities named as antecedent and consequent, by the means of division. For example, when we cook food, then each ingredient has to be added in a ratio. Thus, we can say, a ratio is used to express one quantity as a fraction of another quantity.
Two ratios are equivalent to each other if one of them can be expressed as the multiple of the other. Hence, to get the equivalent ratio of another ratio, we have to multiply the two quantities (antecedent and consequent) by the same number.
Given ratios are 2:1 and 3:1
we can write it as 2/1 and 3/1.
The lcm of 2 and 3 is 6.
Multiply denominator of both ratio with 6, we get
2/6 and 3/6 And we can see both the ratios are not equal.
Hence, there are not equivalent ratios.
4:1 and 8:3 are equivalent ratios -----> is false, because 4:1 is equivalent to 8:2
11:2 and 2:11 are equivalent ratios------> is false (because, are reciprocal ratios, not equivalent ratios)
3:1 and 9:3 are equivalent ratios ------> is true
because 3:1 multiply both sides by 3 -----> 3*3:1*3=9:3

Solve the equation 1-2/x^2 = -x-1
x = ?
The value of x in the expression 1 - (2/x²) = - x - 1 is ± √2, 4.
What is a factor of a polynomial?We know that if x = a is one of the roots of a given polynomial x - a = 0 is a factor of the given polynomial.
To confirm if x - a = 0 is a factor of a polynomial we replace f(x) with f(a) and if the remainder is zero then it is confirmed that x - a = 0 is a factor.
Given, An expression 1 - (2/x²) = - x - 1.
- (2/x²) + x = 2.
Multiplying each term by x².
- 2 + x³ = 2x².
x³ - 2x² = 2.
x²(x - 2) = 2.
x² = 2 ⇒ x = ± √2 Or x - 2 = 2 ⇒ x = 4.
