The length of the drawing on the map for 36 miles is given by the equation A = 4 1/2 inches
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Let the number of miles be = 12 miles
So , 12 miles on the drawing represents = 1 1/2 inches
Now , the number of miles = 36 miles
12 x 3 = 36 miles
And , 36 miles on the drawing represents = 3 x 12 miles on the drawing
Substituting the values in the equation , we get
36 miles on the drawing represents A = 3 x ( 1 1/2 )
On simplifying the equation , we get
36 miles on the drawing represents A = 4 1/2 inches
Hence , the value on the drawing is 4 1/2 inches

Write an equation for the total amount y after the given rate of increase is added to the original amount x.
20%
Answer:
y = 1.2x
Step-by-step explanation:
The given original amount is x.
Increase = 20%
Increase = [tex]\frac{20}{100}[/tex]
Increase = 0.2
Amount of increment = 0.2x
Total amount = Original amount + Amount of increment
y = x + 0.2x

what is the standard form of the quadratic function that has a vertex of (4,-2)and goes through the point ( 5,0)
A. y = 2x^2 - 16x + 30
B. y = 2x^2 - 16x + 32
C. y= 2 (x - 4)^2 - 2
D. y = 2x^2 - 8x - 2
Answer:
C: y = 2(x - 4) - 2
Step-by-step explanation:
The vertex formula of a quadratic is y - k = m(x - h).
Here the vertex is at (4, -2), and so we now have y + 2 = a(x - 4).
Find a: letting y = 0 and x = 5, we get 0 + 2 = a(5 - 4), which means a = 2.
The desired equation is C: y = 2(x - 4) - 2

Step-by-step explanation:
Solve the equation 4(c-3)=8
What are two ways to start solving this equation?
We are given the Equation
4(c - 3) = 8
The two ways to start solving this Equation is given as:
1. 4(c - 3) = 8
We expand the brackets, using Distributive property
4c - 12 = 8
Or
2. 4(c - 3) = 8
Divide both sides by 4
4(c - 3)/4 = 8/4
c - 3 = 2
Therefore, options b and c is correct

Jared and Morgan are making two gazebos in the shape of regular polygons, Jared's gazebo is a heptagon
and has an apothem of 13.6 feet and an area of 623.5 ft and Morgan's gazebo is an octagon has an
apothem of 12.5 feet and an area of 517.8 ft". Which gazebo has the longest side length?
The gazebo with the longest side length is the heptagon.
What is the side length of the heptagon?
A heptagon is a polygon with 7 sides. It has 7 edges and vertices.
The length of the side of a heptagon = (area of the heptagon x 2) / (number of sides x length of the apothem)
= (623.5 x 2) / (7 x 13.6)
= 1247 / 95.2
= 13.1 feet
What is the side length of the octagon?
A octagon is a polygon with 8 sides. It has 8 edges and vertices. The sum of internal angles in 135 degrees.
The length of the side of a octagon = (area of the octagon x 2) / (number of sides x length of the apothem)
= (517.8 x 2) / (12.5 x 8)
= 1035.6 / 100
= 10.356 feet

Answer: The winning order is:
Spike
Boris
Percival.
Step-by-step explanation:
We can write the number of steps that each one did as linear relationships of the form:
y = a*x + b
where:
a represents the slope, in this case, is the velocity of each kid.
x represents the time
b represents the steep at which each one starts.
We know that the race is completed with 99 steps.
Now, we know that in one unit of time (we do not know how long this is, and this does not matter).
Boris can run 5 steps in one unit of time
Spike can run 4 steps in one unit of time
Percival can run 3 steps in one unit of time.
Now let's write the equations for each one.
B(x) will be Boris's equation, we know that he starts from the bottom, then his equation is:
B(x) = 5*x + 0
B(x) = 5*x
Now we can find the number x needed to reach the 99 step, this is:
B(x) = 99 = 5*x
99/5 = x = 19.8
Boris needs 19.8 units of time to finish the race.
S(x) will be the equation for Spike, we know that he starts 21 steps up, then his equation is:
S(x) = 4*x + 21
Let's find the value of x such that S(x) = 99
S(x) = 99 = 4*x + 21
99 - 21 = 4*x
78 = 4*x
78/4 = x = 19.5
So Spike needs 19.5 units of time to finish the race, so he needs less time than Boris, this means that he finishes before Boris.
P(x) is the equation for Percival, we know that he starts 38 steps up, then his equation is:
P(x) = 3*x + 38
Again, we want to find the value of x such that P(x) = 99
P(x) = 99 = 3*x + 39
99 - 38 = 3*x
61 = 3*x
61/3 = x = 20.33
So Percival needs 20.33 units of time to finish the race, he is the one that needs more time, so he will be the last one to finish.
The winning order is:
Spike
Boris
Percival.

What is Future Value?The worth of a current asset at some point in the future based on an estimated rate of growth is known as future value (FV). For investors and financial planners, the future value is crucial because they use it to predict how much an investment made now will be worth in the future.

P = $70000
R= 6.8%
SV = $99000
For Compounded Daily
A = P [tex](1+ (R/100)/ 365) ^{365n[/tex]
99000 = 70000 [tex](1+ (0.068/100)/ 365) ^{365n[/tex]
