Answer:
23/6 or 3 5/6
Step-by-step explanation:
Well, here you just have to subtract and think about the question.
Walk = 9 5/6
Run = 1 1/3
9 5/6 - 1 1 /3 = 23/6

Rotation 180 degrees counterclockwise direction about the origin
Rotation 90 degrees counterclockwise about the origin.
====================================================
Explanation:
Plot a point at the origin. Let's call it point D.
Form segments AD and A'D.
Use the slope formula to note that those segments have negative reciprocal slopes, which leads to the segments being perpendicular.
This proves we have a 90 degree rotation. The direction is counterclockwise when going from A to A'.
The same idea applies when going from B to B', and also C to C'.
The transformation that changes triangle ABC to triangle A'B'C' is a reflection of the y-axis followed by a translation up by 8 units.
Option B is the correct answer.
What is a reflection?There are two ways of translation.
Along x-axis:
(x, y) – (x, -y)
Along y-axis:
(x, y) - (-x, y)
We have,
To determine the transformation that changes triangle ABC to triangle A'B'C', we need to find the transformation that maps each vertex of triangle ABC to the corresponding vertex of triangle A'B'C'.
To map A to A', we need to move 10 units to the right (from x = -5 to x = 5) and stay at the same y-coordinate (y = -6).
This is a horizontal translation of +10 units.
To map B to B', we need to move 1 unit to the left (from x = -3 to x = 2) and 1 unit up (from y = -2 to y = -3).
This is a horizontal translation of -1 units followed by a vertical translation of +1 units.
To map C to C', we need to move 2 units to the right (from x = -4 to x = 6), and 2 units up (from y = -6 to y = -4).
This is a horizontal translation of +10 units followed by a vertical translation of +2 units.
Therefore,
The transformation that changes triangle ABC to triangle A'B'C' is a reflection of the y-axis followed by a translation up by 8 units.

Using the net what is the total surface area of the shoe box below
Answer:
SA = 280 in²
Step-by-step explanation:
The net comprises:
2 rectangles with width 5 in and length 10 in2 rectangles with width 6 in and length 10 in2 rectangle with width 5 in and length 6 inTo calculate the surface area (SA), calculate the area of each rectangle and add them together.
Area of a rectangle = width x length
Therefore, SA of net = 2(5 x 10) + 2(6 x 10) + 2(5 x 6)
⇒ SA = 100 + 120 + 60
⇒ SA = 280 in²

8. Look at the growing pattern below. How many squares will it
take to make the nth figure in this pattern?
Step-by-step explanation:
the first thing we notice is : there are always 2 "extra" squares (1 added to the bottom left, and 1 added to the top right).
and then we see that we have a "core" of n+1 squares that are added n-1 times.
e.g. for n=2 we get (2+1)(2-1) = 3×1 = 3 squares in the middle.
for n=3 we get (3+1)(3-1) = 4×2 = 8 squares in the middle.
just to verify for n=1 : that would be (1+1)(1-1) = 2×0 = 0. meaning no middle squares, which is correct.
so, the formula for n is
squares(n) = (n+1)(n-1) + 2 = n² - 1 + 2 = n² + 1
The number of squares that it takes to make the nth figure in this pattern will be n² + 1.
What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
PEMDAS rule means for the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.
The growing pattern will be
⇒ (n+1)(n-1) + 2
⇒ n² - 1 + 2
⇒ n² + 1
Where n is the integer number.

Find the surface area of the net below.
Answer:
472 in²
Step-by-step explanation:
This net is made up of 3 identical rectangles and 2 identical triangles.
Area of a rectangle = width x length
Area of a triangle = 1/2 x base x height
Rectangle
width = 8 inlength = 19 inTriangle
base = 8 inheight = 2 inSurface Area
SA = 3(8 x 19) + 2(0.5 x 8 x 2)
⇒ SA = 456 + 16

What is the total surface area of rectangular prism?
Answer:
162 [m²].
Step-by-step explanation:
required surface is:
A=(3*7+6*7+3*6)*2=162 [m²].
Answer:
So surface area is calculated by
2lw + 2lh + 2hw = SA
L is length
W is width
H is Height
SA is surface area.
So plug it in, (reminder this equation only works for cubes, rectangular prisms)
2(3)(6) + 2(3)(7) + 2(7)(6) = ?
So now follow order of operations to solve.
36 + 42 + 84 = 162
So 162m^2 is the surface area.

Suzie is going to run for 32 minutes. She can run 1 mile in 5 minutes and she cools off for 7
minutes. How many miles can she run in her time limit?
Answer:
5 miles
Step-by-step explanation:
Let's first break down the question.
Suzie has a total of 32 minutes for her run. She runs 1 mile in 5 minutes and then after running she cools down for 7 minutes.
So then, now for the math...
5 + 5 + 5 + 5 + 5 + 7 = 32 minutes
5 * 5 = 25
25 + 7 = 32
During her time limit she will run a total she will run 5 miles.

Step-by-step explanation:
I assume they intersect at a right angle (90°).
then the intersection is a rectangle with one side being 12 m, and the diagonal being 13 m long.
the diagonal is the Hypotenuse (baseline) of a right-angled triangle with the length and the width of the rectangle as legs.
so, by using Pythagoras we have
diagonal² = length² + width²
13² = 12² + width²
169 = 144 + width²
25 = width²
width = 5 m
so, Oakdale Avenue is 5 m wide.
what are the solutions to this polynominal when s(x)=0? S(X)= (3x^2+17x +10)(x-7)(4x-3)
Answer:
-5, -2/3, 7, 3/4
Step-by-step explanation:
The solutions of S(x) = 0 satisfy one of the equations:
3x^2 + 17x + 10 = 0, x - 7 = 0, 4x - 3 = 0
The latter two are straightforward to solve:
x = 7 and x = 3/4
We now factor 3x^2 + 17x + 10 = 0
Note 10 = 5 * 2, 3 = 3 * 1 and 3 * 5 + 2 - 17.
So, we can factor it as (3x + 2) (x + 5) = 0
Thus, we also have solutions -2/3, -5.

Write a polynomial in standard form that meets the following conditions. Assume a=1 and your function is f(x), The zeros are 5 and -4
Polynomials are equations that uses variables and several terms
The polynomial in standard form is f(x) = x^2 - x -20
How to determine the polynomialThe polynomial has 2 zeros.
So, the form of the polynomial is:
f(x) = a(x - x1)(x - x2)
The zeros of the polynomial are 5 and -4.
So, the equation becomes
f(x) = a(x - 5)(x + 4)
The value of a = 1.
So, we have;
f(x) = 1(x - 5)(x + 4)
This gives
f(x) = (x - 5)(x + 4)
Expand
f(x) = x^2 - x -20
Hence, the polynomial in standard form is f(x) = x^2 - x -20
