A hiker is walking down a mountain. She walked 5978 feet in 17 minutes. In that time she descended 1024 feet feom the top of the mountain. She then walked 3927 feet in 7 minutes. In that time she descended 500 more feet. Express the average rate of change in altitude of the hiker from her starting point to her ending point as unit rate
Answer:
[tex]Average \ rate \ of \ change =[/tex] 63.5 ft/min
Step-by-step explanation:
Given that:
A hiker is walking down a mountain.
For the first case:
She descended 1024 feet from the top of the mountain in 17 minutes after walking for 5978 feet.
For the second case:
She descended 500 more feet from the top of the mountain in 7 minutes after walking for 3927 feet.
Thus; the average rate of change in altitude of the hiker from her starting point to her ending point can be expressed as:
[tex]Average \ rate \ of \ change = \dfrac{h_1 +h_2}{t_1 + t_2}[/tex]
[tex]Average \ rate \ of \ change = \dfrac{1024 +500}{17 + 7}[/tex]
[tex]Average \ rate \ of \ change = \dfrac{1524}{24}[/tex]
[tex]Average \ rate \ of \ change =[/tex] 63.5 ft/min

Step-by-step explanation:
What value is multiplied on both sides of the equals sign?
Answer:
image?????
Step-by-step explanation:
Given the function defined in the table below, find the average rate of change, in
simplest form, of the function over the interval 0 < x < 3.
Note: in decimal form, this fraction converts to roughly 34.67
=========================================================
Explanation:
Highlight the rows that have x = 0 and x = 3. Cross out or cover the other two rows up.
The two rows that have x = 0 and x = 3 show y = f(x) = 4 and y = 108 respectively.
So we have the two points (0,4) and (3,108). We need to find the slope of the line through these points to find the average rate of change from x = 0 to x = 3.
Turn to the slope formula
m = (y2-y1)/(x2-x1)
m = (108-4)/(3-0)
m = 104/3
We cannot reduce the fraction further.
Using a calculator,
104/3 = 34.67 approximately
Si a2 - b2 = 7 (a + b), entonces a - b =
♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️
[tex](a + b)(a - b) = 7(a + b)[/tex]
Divide sides by ( a + b )
[tex] \frac{(a + b)(a - b)}{(a + b)} = \frac{7(a + b)}{(a + b)} \\ [/tex]
[tex](a - b) = 7[/tex]
[tex]a - b = 7[/tex]

How do i do solving systems using elimination
Answer:
The elimination method for solving systems of linear equations uses the addition property of equality. You can add the same value to each side of an equation. So if you have a system: x – 6 = −6 and x + y = 8, you can add x + y to the left side of the first equation and add 8 to the right side of the equation.

Miss bell decorates her gazebo with colored lights. The base of the gazebo is a circle with a diameter of 12 feet. Using the same length of lights she's going to decorate the side of her garden shed which has a square base. What is the maximum side length of the shed
Answer:
The maximum side length of the shed = 9.42 ft
Step-by-step explanation:
From the given information:
Miss bell decorates her gazebo with coloured lights who base is a circle with diameter 12 feet. The first find the circumference of the gazebo by using the circumference of a circle since the base takes such shape.
Circumference of a circle = πd
Circumference of a circle = π × 12
Circumference of a circle = 37.699
Then; the circumference of the circle equates to the length of the lights.
However, using the same length, the maximum side length of the garden shed whose base took a square form can be determined by using the perimeter of a square as the square length, which is;
P = 4L
where;
L = length of sides
37.699 = 4L
L = 37.699/4
L = 9.42 ft
Thus, the maximum side length of the shed = 9.42 ft

A car travels 50 miles per hour, h. What expression represents the total distance you’ve traveled?
Answer:
d = 50h
Step-by-step explanation:
d = distance , h = hours , 50 miles an hour , so 50h
The expression that represents the total distance traveled is 50h .
What is the meaning of Distance ?Distance is the measure of total movement from one place to another , It is a scalar quantity and can be expressed as m and is not dependent upon the direction of the motion.
It is given that
A car travels 50 miles per hour
expression that represents the total distance traveled = ?
Speed = Distance / Time
Given speed = 50 miles/hour
Let h represents the total time
50 = Distance traveled/h
Distance Traveled = 50 h
Therefore the expression that represents the total distance traveled is 50h .

If A = -1 +5n2 + 9 and B = 3 – n, find an expression that equals 2 A – 3B
in standard form.
Answer:
10n² + 3n + 7
Step-by-step explanation:
2A - 3B = 2.( -1 + 5n² + 9) - 3.(3 - n)
= -2 + 10n² + 18 - (9 - 3n)
= 10n² + 16 -9 + 3n
= 10n² + 3n +7
the sum of two numbers is 181 and their difference is 37.Find the larger of the two integers
Answer:
Larger First number: 109
Second number: 72
Step-by-step explanation:
x + y = 181
x - y = 37
x = 37 + y
(37 + y) + y = 181
37 + y + y = 181
37 + 2y = 181
2y = 144
y = 72
x - y = 37
x - 72 = 37
x = 109
Check:
x + y = 181
109 + 72 = 181
181 = 181
x - y = 37
109 - 72 = 37
37 = 37
Larger number is x = 109

Is 4(3x – y) and 12x – 4y equivalent? yes or no, if so how is it? HELP ASAP PLEASE AND THANK YOU!
Answer:
Yes!
Step-by-step explanation:
If you distribute 4 into 3x-y, you will get the same thing (12x-4y) meaning they are equivalent.
Answer:
Yes
Step-by-step explanation:
4(3x - y) | 12x - 4y
12x- 4y = 12x - 4y
hence they are equivalent
