A mother gives birth to a 7-pound baby. Every 3 months, the baby gains 2 pounds. If x is the age of the baby in months, then y is the weight of the baby in pounds. Find an equation of a line in the form y=mx+b that describes the baby's weight.
y =___________________
Answer:
y = 2/3 x + 7
Step-by-step explanation:
At birth represents the beginning of time for the baby. Lets call this month zero. So here are your coordinates.
x = 0 y = 7 ----> at birth
x = 3 y = 9
x = 6 y = 11
x = 9 y = 13
Now we find the slope between each point. Since the common difference of y is 2 and the common difference in x is 3 , the slope will be
slope = y / x = 2 / 3
Therefore, the equation of the line that represents this relationship is
y = (2/3) x + 7
On a team, 7 girls and 6 boys scored a total of 79 points. The difference between the number of points scored by the 7 girls and the number of points scored by the 6 boys is 19. Each girl scored the
same number of points and each boy scored the same number of points. Find the number of points scored by each girl and each boy.
Each girl scored 9 points
Each boy scored 7 points
Step-by-step explanation:
Let the number of points each girl scored = a
Let the number of points each boy scored = b
7 girls and 6 boys scored a total of 105 points.
7a + 6b = 105......... Equation 1
The difference between the number of points scored by the 7 girls and the number of points scored by the 6 boys is 21
7a - 6b = 21........... Equation 2
7a + 6b = 105......... Equation 1
7a - 6b = 21........... Equation 2
Subtract Equation 2 from Equation 1
12b = 84
b = 84/12
b = 7
Therefore, each boy scored 7 points
7a + 6b = 105......... Equation 1
b = 7
7a+ 6b = 105
7a + 6(7) = 105
7a + 42 = 105
7a = 105 - 42
7a = 63
a = 63/7
a = 9
Therefore, each girl scored 9 points.

The distance between the centres of two villages is 8 km.
A map on which they are shown has a scale of 1:50000.
Calculate the distance between the centres of the two villages on the map. Give your answer in centimetres.
The distance between the centres of the two villages on the map is 16cm. The solution is obtained using the concept of unit conversion.
What is unit conversion?The same attribute is expressed using a unit conversion, but in a different unit of measurement. For instance, time can be expressed in minutes rather than hours, and distance can be expressed in kilometres, feet, or any other measurement unit instead of miles. Measurements are frequently offered in one set of units, like feet, but are required in another set, like chains.
Now, we are given the scale of a map as 1 : 50000 and that two villages are 8km apart on the map.
The scale of a map is given as 1 : 50000.
=> 1 cm on map = 50,000 cm on actual
We know that 1 km = 1,00,000cm
So,
=> 8km = 8,00,000 cm
So, The distance on the map is
800000 / 50000
= 80/5
= 16 cm
Hence, the actual distance between them is 16cm.

You have two different saving accounts.for A, the interest earned after 18 months is 12.00. For account B, the interest earned after 27 months is 27.00 Which account earned you the most interest in the first year? Explain your answer
Account A earned the most interest in the first year, since it earned 12.00 in 18 months compared to the 27.00 earned by Account B in 27 months.
Which account earned you the most interest in the first year?This means that Account A earned 12.00 in 1 year, while Account B only earned 9.00 in the same time period.The account that earned you the most interest in the first year depends on the interest rate for each individual account.To find out which account earned you the most in the first year, we can use the equation A = P(1+r/n)^nt. In this equation, A stands for the amount of money in the account, P stands for the principal amount, r stands for the interest rate, n stands for the number of times the interest is compounded per year, and t stands for the number of years. For account A, plugging in the numbers given, we get A = P(1+12/18)^18. In this equation, P represents the principal amount in account A after the first year.For account B, plugging in the numbers given, we get A = P(1+27/27)^27. In this equation, P represents the principal amount in account B after the first year. By comparing the two equations, we can determine which account earned you the most interest in the first year.If we compare the two equations, we find that account B earned you more interest than account A in the first year because the interest rate for account B was higher than the interest rate for account A. Therefore, account B earned you the most interest in the first year.To learn more about earning interest at different rates refer to:

f(x) = √(x + 7), g(x) = √(x - 7)
Find the domain of f.
Answer:
[tex]x\ge -7[/tex]
Step-by-step explanation:
Square Root Function:The square root function has a domain consisting of numbers greater than or equal to zero. This excludes negative numbers since the square root of a number, when multiplied by the same square root of a number results in the original number: [tex]y=\sqrt{x}\implies y*y=x[/tex]. If we wanted the square root of a negative number, we would need a number which multiplies by it self to get a negative number, but as you may recall, if we square a real number, we always get a positive. So negative numbers are not included in the domain (although there are imaginary solutions)
So we just need the inside of the square root to be greater than or equal to zero. Thus we can derive: [tex]x+7\ge 0[/tex] and then just subtract 7 from both sides to simplify: [tex]x\ge -7[/tex] and now we have our domain in interval notation.
. 10 people can fit comfortably into a 7 x 12 feet square. What is the ratio of number of people and the
rectangle's area?
Answer:
5 people per 42 square feet.
Step-by-step explanation:
The area of the rectangle is 7 x 12 = 84 square feet.
The ratio of the number of people to the area of the rectangle is:
10 people : 84 square feet
You can simplify this ratio by dividing both sides by 2:
10/2 people : 84/2 square feet
Which can be written as
5 people : 42 square feet
Answer:
The ratio of the number of people to the rectangle's area is 10 people : 84 square feet.
Step-by-step explanation:
The ratio of the number of people to the rectangle's area is 10 people : 84 square feet.
It is important to note that this ratio represents the maximum number of people that can fit comfortably in the 7 x 12 feet square. The actual number of people that can fit in the space will depend on various factors such as the size and layout of the room, the presence of furniture, and the size of the people.

Suppose a parabola has an axis of symmetry at x = 6, a maximum height of 6 and also passes through the point (7, 5). Write the equation of the parabola in vertex form.
The equation of the parabola, in vertex-form, is given as follows:
y = -(x - 6)² + 6.
What is the equation of a parabola given it’s vertex?The equation of a quadratic function, of vertex (h,k), is given by the rule presented as follows:
y = a(x - h)² + k
In which the parameters of the equation are given as follows:
h is the x-coordinate of the vertex.k is the y-coordinate of the vertex.a is the leading coefficient.The axis of symmetry is at x = 6, hence:
h = 6.
The maximum height if of 6, hence:
k = 6.
Thus:
y = a(x - 6)² + 6.
The parabola passes through the point (7,5), meaning that when x = 7, y = 5, and thus the leading coefficient a is obtained as follows:
5 = a(7 - 6)² + 6.
a = -1.
Hence the parabola is defined as follows:
y = -(x - 6)² + 6.

A squad of 14 players is selected for a mixed football tournament.
The rules state that the ratio of boys to girls per squad must be no greater than 3:2
What is the maximum number of boys that can be selected for the squad?
Answer:
Step-by-step explanation:
The ratio of boys to girls in the squad must be no greater than 3:2. This means that for every 3 boys, there must be at least 2 girls.
Since the total number of players in the squad is 14, we can set up the following equation:
3x + 2y = 14
Where x is the number of boys in the squad, and y is the number of girls in the squad.
To find the maximum number of boys that can be selected for the squad, we need to find the highest possible value of x while still satisfying the equation.
We know that x, the number of boys, is a whole number, so we can start testing values of x by subtracting 2 from both sides and then dividing by 3
x = (14 - 2y)/3
If we start testing values for y and substituting it back into the equation, we'll find that the maximum value for y is 6, and the corresponding value for x is 5.
35 + 26 = 15 = 14
Therefore, the maximum number of boys that can be selected for the squad is 5.

The students that have both a Netflix and Hulu account is 12.
How to calculate the number?We can use the principle of inclusion-exclusion to solve this problem. The principle states that if we want to know how many students have either a Netflix or a Hulu account (or both), we can add the number of students who have a Netflix account to the number of students who have a Hulu account and then subtract the number of students who have both.
So, using the information given:
Netflix or Hulu = Netflix + Hulu - (Netflix and Hulu)
87 = 53 + 46 - (Netflix and Hulu)
To find the number of students who have both a Netflix and Hulu account we can solve for (Netflix and Hulu) :
(Netflix and Hulu) = Netflix + Hulu - 87
(Netflix and Hulu) = 53 + 46 - 87
(Netflix and Hulu) = 12

The angles which measure 20 degrees are∠1 ,∠5 ,∠7 ,∠9 ,∠11 ,∠14 ,∠16. The solution has been obtained using the properties of parallel lines.
What are parallel lines?Parallel lines are any two or more lines that lie in the same plane, are equally spaced apart, and never cross one another.
We are given t || x and k || w and m∠3 = 20°
Using the properties of parallel lines, we get -
∠3 = ∠1 (As these are vertically opposite angles)
∠3 = ∠5 (As these are alternate interior angles)
∠3 = ∠7 (As these are corresponding angles )
Now,
∠4 = 180 - ∠3 (As they form a linear pair)
∠10 = 180 - ∠9 (As they form a linear pair)
Also,
∠10 = ∠4 (Parallelogram's opposite angles are same)
So,
180 - ∠9 = 180 - ∠3
∠3 = ∠9 .... [ii]
∠9 = ∠11 (As these are vertically opposite angles)
∠3 = ∠11 ( from [ii] ) .... [iii]
∠11 = ∠14 (As these are alternate interior angles)
∠3 = ∠14 ( from [iii] ) .... [iv]
∠14 = ∠16 (As these are vertically opposite angles)
∠3 = ∠16 ( from [iv] )
Hence, the angles which measure 20 degrees are
∠1 ,∠5 ,∠7 ,∠9 ,∠11 ,∠14 ,∠16.

A spherical water tank has a radius of 25 feet. Can it hold enough water to fill a swimming pool 50 meters long, 25 meters wide with a constant depth of 2 meters?
Show your work by comparing each cubic feet
The spherical water tank can not hold enough water to fill up the swimming pool, given the length, width, and constant depth of the water.
How to find the amount of water ?The amount of water that the spherical tank can hold is the volume of the spherical tank. This volume can be found by the formula:
= 4 / 3 x Pi x radius ³
The volume of this spherical tank is therefore :
= 4 / 3 x Pi x 25 feet
= 65, 450 feet ³
Then, to see if it can hold enough water for a swimming pool 50 meters long, 25 meters wide with a constant depth of 2 meters, find the volume of the swimming pool as:
= Length x Width x Depth
= 50 x 25 x 2
= 2, 500 meters ³
1 m³ to feet ³ is 35.3147 so the volume in feet is:
= 2, 500 x 35.3147
= 88, 287 feet ³
