The graph models the height h, in meters, of a
hot air balloon, t minutes after beginning to
descend. How high was the balloon when it
began its descent?
The balloon was _ m high when it began its descent
Answers
Answer:
85 m high
Step-by-step explanation:
The greatest height of the Ballon whn it began it's descent is given by the intercept value of the graph. Hence, the height of Ballon when it began it's descent is 80 meters.
The slope of the graph is negative signifying that the value on the y-axis decreases as the value on the x - axis increases.
The y - intercept is the value of y when x=0. This value represents the height at time = 0; when descent is about to begin. Hence, the ballon was 80 meters high.

Diana is comparing the membership costs at two fitness centers. The community fitness center costs $60 per month. The fitness center located where she works has a $100 registration fee and costs $40 per month. After how many months of membership will the costs be the same? 2 3 4 5
Answers
Answer:
The indifference point is 5 months.
Step-by-step explanation:
First, we need to structure the total cost formula for each fitness center:
Community center= 60x
Work center= 100 + 40x
x= number of months
Now, we equal the formulas and isolate x:
60x = 100 + 40x
20x = 100
x= 5
The indifference point is 5 months.

A thin wire 40 CM long is formed into a rectangle if the width of this rectangle is 8 CM what is length and area
Answers
Length of a wire = 40 cm.
Breadth of the rectangle formed = 8 cm.
Find:length and area of rectangle.
Solution:Length of a wire = 40 cm.
A rectangle is made from this wire.
That means,
Perimeter of the rectangle formed = length of the wire.
Also,
Breadth of the rectangle formed = 8 cm.
We know that,
Perimeter of a rectangle = 2(length + breadth).
Let the length of the rectangle be x cm.
Hence,
→ 2(x + 8) = 40
→ 2x + 16 = 40
→ 2x = 40 - 16
→ 2x = 24
→ x = 24/2
→ x = 12
Hence,
Length of the rectangle formed = x = 12 cm.
Now,
We know,
Area of a rectangle =length * breadth
→ Area of the rectangle = (12) * (8)
→ Area of the rectangle = 96 cm²
Therefore, the area of the rectangle formed is 96 cm².
I hope it will help you.

Write an equation and show your work: There were five different Foil Kites that each descend 50 feet per second for 5 seconds. Find the total change in altitude for all 5 kites.
Answers
Answer: Change in altitude = (50 x 5) feet
The total change in altitude for all 5 kites. = 250 feet
Step-by-step explanation:
Given : Rate of descent = 50 feet per second (speed)
Time = 5 seconds
Since, distance = speed x time
Change in altitude = Rate of descent x Time
Change in altitude = 50 x 5 feet [required equation]
= 250 feet
Hence, the total change in altitude for all 5 kites. = 250 feet

A cat can travel a distance of 32.5 meters in 13 seconds. What is the average speed of the cat to the nearest hundredth of a m/s? *
A 2.5 mph
B 0.4 mph
C 2.5 m/s
D 0.4 m/s
Answers
Answer:
C. 2.5 m/s
Explanation:
Speed can be defined as distance covered per unit time. Speed is a scalar quantity and as such it has magnitude but no direction.
Mathematically, speed is given by the equation;
[tex]Speed = \frac{distance}{time}[/tex]
[tex]S = \frac{d}{t}[/tex]
Given the following data;
Distance = 32.5m
Time = 13secs
Substituting into the above equation;
[tex]S = \frac{32.5}{13}[/tex]
Speed, S = 2.5m/s
