Answer:
[tex]<174\frac{4}{9}[/tex] hopes this helps :D
Step-by-step explanation:
The solution is s > 174 4/9
The inequality equation is s > 174 4/9 and it will take 174 4/9 seconds for the hot air balloon to reach below 215 feet
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 equation be represented as A
Now , the value of A is given by
Let the total altitude of the hot air balloon be = 1000 feet
Now , the hot air to reach below 215 feet , the hot air balloon should descend a total of = 1000 - 215 feet
So , the value of hot air balloon should descend = 785 feet
And ,
The rate at which the hot air balloon descends = 4 1/2 feet per seconds
So , the number of seconds s for the hot air balloon to reach an altitude more than 785 feet is given by the inequality equation A
where ( 4 1/2 ) x s > 785
On simplifying the equation , we get
( 4 1/2 )s > 785
( 9/2 ) s > 785
Multiply by 2 on both sides of the equation , we get
9s > 1570
Divide by 9 on both sides of the equation , we get
s > 174 4/9
Therefore , the value of A is s > 174 4/9
Hence ,
The inequality equation is s > 174 4/9 where s is the number of seconds

find the scale figure from A to B.
scale figure A= 16 cm,8cm,20 cm
scale figure B=12cm,6cm,15cm
Answer:
The scale factor is 4/3 or 1.333...
Step-by-step explanation:
We're trying to find how can A go to B
Example: 16 --> 12
16 Divided by 12 = 4/3
[tex]\frac{16}{1}[/tex]÷[tex]\frac{12}{1} = \frac{16}{1} * \frac{1}{12} = \frac{16}{12} = \frac{4}{3}[/tex]

Question
The value of a computer y, depreciates, or decreases as time passes. A computer was purchased for $3200 in 2018. In
2020 the computer was worth $2000. Assume the relationship between number of years after 2018 x, and value of
computer, y is linear.
The value of the computer decreases by $800 per year.
A linear equation is given by:
y = mx + b
where y, x are variables, m is the rate of change, b is the initial vale of y (y intercept).
Let y represent the cost of the computer and x represent the years after 2018.
A computer was purchased for $3200 in 2018. It is represented by the point (0, 3200). Also, in 2020 the computer was worth $2000, it is represented by the point (2, 2000). Hence:
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-3200=\frac{2000-3200}{2-0}(x-0)\\\\y-3200=-800x\\\\y=-800x+3200[/tex]
Therefore the value of the computer decreases by $800 per year.

A linear relationship will always decrease or increase at a constant and uniform rate.
The linear equation is [tex]\mathbf{y = -600x +3200}[/tex]The estimated value in 2022 is $800The estimated value in 2024 is -$400, and it does not make sensePart 1
(a) The linear equation
In 2018, the value is $3200
In 2020, the value is $2000
Let the number of years since 2018 be x, and the value be y
So, we have the following representation
[tex]\mathbf{(x,y) = (0,3200) (2,2000)}[/tex]
Start by calculating the slope (m)
[tex]\mathbf{m = \frac{y_2 - y_1}{x_2 - x_1}}[/tex]
So, we have:
[tex]\mathbf{m = \frac{2000 - 3200}{2 - 0}}[/tex]
[tex]\mathbf{m = \frac{- 1200}{2}}[/tex]
Divide
[tex]\mathbf{m = - 600}[/tex]
The equation is then calculated as:
[tex]\mathbf{y = m(x -x_1) +y_1}[/tex]
So, we have:
[tex]\mathbf{y = -600(x -0) +3200}[/tex]
[tex]\mathbf{y = -600x +3200}[/tex]
Hence, the linear equation is [tex]\mathbf{y = -600x +3200}[/tex]
(b) The estimated value in 2022
In 2022, x = 4
So, we substitute 4 for x in the linear equation
[tex]\mathbf{y = -600x +3200}[/tex]
[tex]\mathbf{y = -600 \times 4 +3200}[/tex]
[tex]\mathbf{y = 800}[/tex]
Hence, the value in 2022 is $800
Part 2
The estimated value in 2024
In 2024, x = 6
So, we substitute 6 for x in the linear equation
[tex]\mathbf{y = -600x +3200}[/tex]
[tex]\mathbf{y = -600 \times 6 +3200}[/tex]
[tex]\mathbf{y = -400}[/tex]
Hence, the value in 2024 is -$400
This value does not make sense, because the value cannot be negative

Find the perimeter. Simplify your answer.
Answer:
[tex]18x+32[/tex]
Step-by-step explanation:
Perimeter is the total distance around a shape and can be found by calculating the sum of a shape's sides.
In this case, we are given a parallelogram, a quadrilateral with two pairs of parallel sides. Thus, the formula for a parallelogram's perimeter is as follows:
[tex]P=2(a+b)[/tex]
Substitute the variables in the formula for the expressions on the parallel lines:
[tex]a=3x+6[/tex]
[tex]b=6x+10[/tex]
[tex]P=2(3x+6+6x+10)[/tex]
Distribute the 2 into each term:
[tex]P=6x+12+12x+20[/tex]
[tex]P=18x+32[/tex]
Answer:
18x + 32Step-by-step explanation:
Perimeter = 3x + 6 + 6x + 10 + 6x + 10 + 3x + 6
= 18x + 32...ans

Answer:
y = -4x + 4
Step-by-step explanation:
slope formula: y = mx + b
b is always y intercept which is when the line crosses through the y axis while the x coordinate is at 0. that would make it 4. now we find another point which would be (-1,8)
use change in y/change in x
we already have 2 points
(0,4)
(-1,8)
change in x: -1
change in y: 4
4/-1
slope: -4
