Since Building Brothers have been renovating homes for 16 years, the number of homes renovated is 24.
How is the number of homes determined?We can use mathematical operations of addition, subtraction, division, and/or multiplication to determine the missing value.
The first effort is converting 16 years into months. The product is divided by 8 months to arrive at the quotient of 24 homes that were renovated within 16 years.
Data and Calculations:Time period = 16 years
Time spent to renovate a house = 8 months
12 months = 1 year
Total number of months spent = 192 months (16 x 12)
The number of renovations = 24 (192/8)
Thus, Building Brothers have renovated 24 homes within 16 years.

Question is based on the Pythagorean theorem :
Pythagoras' theorem states that “In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides“. The sides of this triangle have been named Perpendicular, Base and Hypotenuse. Here, the hypotenuse is the longest side, as it is opposite to the angle 90°. The sides of a right triangle (say a, b and c) which have positive integer values, when squared, are put into an equation, also called a Pythagorean triple
Consider the triangle given above:
Where “a” is the perpendicular,
“b” is the base,
“c” is the hypotenuse.
According to the definition, the Pythagoras Theorem formula is given as:
X is the side opposite to the right angle, hence it is a hypotenuse.
Now, by the theorem we know;
Hypotenuse2 = Base2 + Perpendicular2
x2 =[tex]4^{2} +3^{2}[/tex]
x2 = 16+9
x = [tex]\sqrt{25}[/tex]

Eli runs a distance of 3 miles in 2/5 of an hour. Jess runs a distance of 4/5 mile in 1/10 of an hour. Who had the faster speed? show your work.
Jess had the faster speed than Eli.
We have the relation connecting Distance travelled, Time taken to travel and the speed given by,
Distance Travelled = Speed x Time taken
Here, we need to find the speed of Eli and Jess to find out who was faster.
So we use the formula, Speed = Distance travelled / Time taken
Distance travelled by Eli = 3 miles
Time taken by Eli = 2/5 hour
Speed of Eli = Distance / Time taken
= 3/(2/5)
= 15/2 = 7.5 miles per hour
Distance travelled by Jess = 4/5 mile
Time taken by Jess = 1/10 hour
Speed of Jess = Distance / Time taken
= (4/5)/(1/10)
= 8 miles per hour
Comparing the speeds of Eli and Jess, Jess had the faster speed of 8 miles per hour.

The kinetic energy T units of a motion body (of constant mass) varies as the square of its speed v m/s. If kinetic energy T = 800 units when speed v= 20m/s: Calculate V when T= 1800.
If T=1800 then V=30m/s.
kinetic energy is nothing but The energy an object has as a result of motion is known as kinetic energy.
Given that,
If T = 800 units when v= 20m/s
Kinetic energy formula is
[tex]T=\frac{1}{2}mv^{2}[/tex]
Here, T is kinetic energy , m is mass and v is speed
Now,
[tex]800=\frac{1}{2}m(20)^{2} \\800\times2=m(400)\\\frac{1600}{400}=m\\ m=4[/tex]
We got mass m as 4
Now, when T= 1800 find v=?
[tex]1800=\frac{1}{2}\times4\times v^{2} \\1800\times2= v^{2} \\ v^{2} =900\\v=30[/tex]

Given difference quotient is f(x) = -x²+2x+5.
Simplified version is (f(x + h) - f(x))/h = 1.
What is difference quotient?If f(x) = x - 5, then
f(h) = h - 5
f(x + h) = (x + h) - 5
(f(x + h) - f(x))/h = (((x + h) - 5) - (x - 5))/h
(f(x + h) - f(x))/h = (x + h - 5 - x + 5)/h
(f(x + h) - f(x))/h = h/h
(f(x + h) - f(x))/h = 1
since h ≠ 0.
The average rate of change of the function over an interval is measured by the difference quotient (in this case, an interval of length h). The instantaneous rate of change is hence the limit of the difference quotient (i.e., the derivative).
The slope of secant lines can be calculated using the difference quotient. Almost identical to a tangent line, a secant line traverses at least two points on a function.
That equation is known as a difference quotient because both the numerator and denominator are differences.

b) She can take 10 sips before she needs to refill.
c) The graph is given at the end of the answer.
d) The domain is: 0 ≤ s ≤ 10.
What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.For this problem, the parameters are given as follows:
m = -12, b = 120.
Hence the function is:
f(s) = 120 - 12s.
She can take sips until f(s) = 0, hence:
120 - 12s = 0
12s = 120
s = 10.
She can take 10 sips before she needs to refill, and hence the domain(set that contains the input values for the function) is 0 ≤ s ≤ 10.

a. What is the difference between the highest and lowest points of the country?
The difference between the highest and the lowest points of the country is 5771 feet.
What is subtraction?The operation of subtraction is used to calculate the difference between two numbers. If you have an object group and remove a couple of them, the object group gets smaller.
The process of subtracting one number from another is called subtraction. The way to calculate the difference between two numbers is by using the basic arithmetic operation of subtraction, which is represented by the symbol (-).
Let the sea level be x.
The highest point of the country is 5,762 feet above the sea. So, we can write it as
x+5,762
Since the lowest point is 9 feet below sea level, we can write this expression:
x-9
The difference is the result of subtraction. Therefore, we can find the expression that represents the difference between the elevations by subtracting x+5,762 and x-9:
(x+5,762)-(x-9)
= x+5762-x+9
= 5762+9

A principal has given a class $75 to help pay for a field trip to a zoo. The students in the class are selling pies for

Which inequality can be used to findp, the number of pies the class needs to sell in order to earn enough money to
pay for the field trip?
A 5p+75 ≤ 386
B 5p+752 386
C 75p+52 386
D 75p+5≤ 386
I'd say its A because:
5x#of pies + the money the principal pitched in (75) is less than or equal to 386 dollars (their goal for the field trip).
The inequality equation is given by 5p + 75 ≤ 386 , where p is the number of pies the class sells
What is an Inequality Equation?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.
Given data ,
Let the inequality relation be represented as A
Let the number of pies the class sells be p
Now , the equation will be
The total amount for the field trip = $ 386
The amount given to the students = $ 75
The cost of 1 pie = $ 5
So , the cost of p pies = 5p
Now , the total amount with the students = cost of p pies + amount given to the students
Substituting the values in the equation , we get
5p + 75 ≤ 386
Therefore , the value of A is 5p + 75 ≤ 386
Hence , the inequality relation is 5p + 75 ≤ 386

Use the elimination method of linear equations to find your answer.
Our equations for this problem are:
3c+5t=52 and 9c+7t=86
1. Multiply the entire first equation by -3.
-3(3c+5t=52)
2. Simplify the equation from above:
-9c-15t=-156
3. Stack the two equations on top of each other and add/subtract:
-9c-15t=-156
9c+7t=86
4. You should be left with -8t=-70. Simplify this to find the value of t:
t=8.75
5. Plug the value of t into any of the original equations and solve for c.
3c+5(8.75)=52
6. Simplify the equation above:
3c+43.75=52
7. Subtract 43.75 from both sides of the equation:
3c=8.25
8. Divide both sides by 3 to get your c value:

he mean life of a tire is 30,000 km. The standard deviation is 2000 km.
Then, 68% of all tires will have a life between ___________ km and __________ km.
The conclusion is that 68% of all tires will have a life between 28000 km and 32000 km.
How to use the Empirical Rule of statistics?
The empirical rule in statistics states that for a normal distribution,
68% of the distribution are within one standard deviation from the mean.95% are within two standard deviation from the mean.99.7% are within three standard deviations from the mean.We are given;
Mean (μ) = 30000 km
Standard deviation (σ) = 2000 km
Using the empirical rule of 68% which lies within one standard deviation from the mean, we have;
μ ± σ = 30000 ± 2000 = (28000, 32000)
Thus, we conclude that 68% of all tires will have a life between 28000 km and 32000 km.
