Answer: Michael is 39 years old.
Step-by-step explanation:
Let l stand for Luis, s stand for Santiago, and m stand for Michael.
l = s - 6
m = 3s
s + (s-6) + 3s = 59
s + s - 6 + 3s = 59
5s - 6 = 59
+6 +6
5s = 65
/5 /5
s = 13
Now plug s into the equation that represents Michael:
m = 3s
m = 3(13)
m = 39
Michael is 39 years old.

Answer:
15%
Step-by-step explanation:
1. Subtract final value from starting value
65 - 55.25 = 9.75
2. Divide 9.75 by original number
9.75/65 = 0.15
3. Multiply quotient by 100 to get percentage
0.15 x 100 = 15%

A piece of copper tubing is in the shape of a hexagonal prism. The area of the base of the prism is 3 square centimeters. The volume of the prism is 51 cubic centimeters. What is the height of the tubing?
Answer: 17 cm
Step-by-step explanation:
For a regular figure where the area of the base is B, and the height is H, the volume is calculated as:
V = B*H
Here we know that the base of the prism is B = 3 cm^2, and the volume of the prism is 51 cm^3
Then:
B = 3cm^2
V = 51cm^3
If we replace those in the equation above, we get:
51 cm^3 = (3cm^2)*H
Solving this for H gives:
(51 cm^3)/(3 cm^2) = H = 17 cm
The height of the tubing is 17 cm

A. 82 in.
B. 32 in.
C. 327 in.
D 16 in.
The circumference of the circle is 32 inches. The correct option is B.
What is circumference?The circumference is the length of the line by which the circle is made. The circle is defined as the locus of the point traces around a fixed point called as the center and is equidistant from the outer trace.
Given that a circle has a diameter of 10.2 inches. The radius of the circle is 5.1 inches.
The circumference of the circle is calculated by the formula,
C = 2πr
C = 2 x π x 5.1
C = 32 inches

In an endurance race, Alyson rode her bicycle 7 miles less than Jeff. Together they rode 39 miles. How far did Alyson ride?
Answer:
Distance cover by Alyson = 16 miles
Step-by-step explanation:
Given:
Distance cover together = 39 miles
Assume;
Distance cover by Jeff = a
Distance cover by Alyson = a - 7
Find:
Distance cover by Alyson
Computation:
a + (a - 7) = 39
2a - 7 = 39
2a = 46
a = 23
Distance cover by Alyson = a - 7
Distance cover by Alyson = 23 - 7
Distance cover by Alyson = 16 miles

Find the x- and y-intercepts of the graph of 3x + 2y = 20. State your answers as
whole numbers or as improper fractions in simplest form.
The x-intercept is given by the coordinates as (x, 0)
i,e y = 0
The y-intercept is given by the coordinates as (0, y)
i.e x = 0
The x-intercept of the graph of 3x + 2y = 20 is at x = 20/3
The y-intercept of the graph of 3x + 2y = 20 is at y = 10
What are coordinates in a graph?
The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.
The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.
We have,
3x + 2y = 20
The x-intercept is given by the coordinates as (x, 0)
i,e y = 0
The y-intercept is given by the coordinates as (0, y)
i.e x = 0
Now,
3x + 2y = 20
Putting x = 0 in (1) we get the y-intercept.
3x + 2y = 20
3x0 + 2y = 20
0 + 2y = 20
2y = 20
Divide both sides by 2.
y = 20/2
y = 10
Putting y = 0 in (1) we get the x-intercept.
3x + 2y = 20
3x + 2 x 0 = 20
3x + 0 = 20
3x = 20
Divide both sides by 3.
x = 20/3
Thus,
The x-intercept of the graph of 3x + 2y = 20 is at x = 20/3
The y-intercept of the graph of 3x + 2y = 20 is at y = 10

What is the area of the polygon below.
Answer:
336 ft²
Step-by-step explanation:
The figure is composed of a rectangle and a right triangle
A of rectangle = length × breadth = 24 × 12 = 288 ft²
A of Δ = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )
Here b = 32 - 24 = 8 ft and h = 12 , then
A of Δ = [tex]\frac{1}{2}[/tex] × 8 × 12 = 4 × 12 = 48 ft²
composite area = 288 + 48 = 336 ft²

PLS HELP a parabola has the equation y = 4x^2 + bx -2 and the equation for the axis of symmetry is x = -1.
Answer:
Step-by-step explanation:
Remark
Unless you know calculus, the only way to solve this is by completing the square.
Solution
y = 4x^2 + bx - 2
y = 4(x^2 + b/4 ) - 2
y = 4(x^2 + b/4 + (1/2b/4)^2 ) - 2 - 4*(b/8)^2
y = 4(x^2 + b/4 + (b/8)^2 ) - 2 - b^2/16
y = 4(x + b/8)^2 - 2 - b^2/16
Now what you want to happen is to give b/8 a value of 1 so that when x is put in -1 you get 0 for what is inside the brackets.
b/8 = 1
b = 8
y = 4(x + 1)^2 - 2 - (8)^2 / 16
y = 4(x + 2)^2 - 2 - 4
y = 4(x + 1)^2 - 6
The vertex is at (-1, - 6)
The axis of symmetry is x = - 1
Note
This could have been done a lot shorter just by realizing that the number inside the brackets had to be + 1 as in (x + 1). But then you would not have been able to know the minimum value for y which is - 6
