here is a spreadsheet to help you understand the stair problem notice for 1 step 1 block, 2 step, 3 block, 3 step, 6 block and so on notice the blocks for the number of a step is that step plus all the other blocks needed to make all the one(s) below it. Notice it takes 105 blocks to make 14 steps.
So if you are familiar with the summation process you would add the number that go with that stair with all the stairs below it. example step 5 blocks would be 5 + 4 + 3 + 2 +1 or 15 blocks. I hope this gets you started. The second part I do not understand the problems because they are not equations. NO equal signs

The straight-line distance after walking 9 blocks east and 5 blocks north can be calculated using the Pythagorean theorem, resulting in a distance of approximately 10.3 blocks, which is shorter than the total 14 blocks walked.
Explanation:The question involves finding the straight-line distance between two points in a two-dimensional city grid.
When walking 9 blocks east and then 5 blocks north, you are creating a right-angled triangle where the straight-line distance is the hypotenuse of the triangle.
To calculate this, we can use the Pythagorean theorem.
To find the straight-line distance, you square the number of blocks walked east (9 blocks squared) and north (5 blocks squared), and then find the square root of their sum:
Hypotenuse = √((9 blocks)² + (5 blocks)²).
This results in a straight-line path of √(81 + 25) = √106, which is approximately 10.3 blocks.
Hence, even though you walked 14 blocks, the straight-line path is only about 10.3 blocks long, which is considerably shorter than the path you walked.

Which is a better estimate for the length of an ironing board?
Answers
A better estimate for the length of an ironing board would be 120 inches, or 10 feet. This exercise illustrates the importance of carefully calculated approximations rather than relying on rough 'guesstimates'.
Explanation:A better estimate for the length of an ironing board would be 120 inches, or 10 feet. This estimate is closer to the final approximate value mentioned in the discussion. However, the early estimate of 3 inches was significantly off. This exercise illustrates the importance of carefully calculated approximations rather than relying on rough 'guesstimates'.
Anna buys 24 seeds and plants 3 in each pot. She has 5 pots. How many more pots does Anna need to plant all of her seeds
Answers
The number of pots required to plant 24 seeds will be 8.
What is an expression?The mathematical expression is the combination of numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also be used to denote the logical syntax's operation order and other properties.
Given that Anna buys 24 seeds and plants 3 in each pot. She has 5 pots.
The number of the pots will be calculated as Anna needs 3 more pots. 3 times 5 is 15 seeds. And she has 24 seeds. so 24 divided by 3 is 8. 8 minus 5 is 3.
Number = 24 / 3 = 8 pots
Therefore, the number of pots required to plant 24 seeds will be 8.

To convert a percent to a demical move the number to the right twice. Or divide the number by 100. 50 divided by 100 = 0.5

A water tank contains 1,250 gallons of water. The water is used to fill some 30 gallon barrels. What is the number of the barrels that can be completely filled and how much water is left?
Answers
A total of 41 barrels can be completely filled with 1,250 gallons of water, leaving 20 gallons of water leftover in the tank.
Suppose a water tank contains 1,250 gallons of water and this water is used to fill 30-gallon barrels. In that case, we can calculate the number of barrels that can be completely filled and the remaining water by dividing the total water volume by the volume of one barrel.
First, divide 1,250 gallons by 30 gallons per barrel:
[tex]\frac{1250}{30}[/tex] = 41.66
This division gives us 41 complete barrels, with a remainder indicating that 20 gallons of water will be left.
Therefore, 41 barrels can be completely filled, and 20 gallons of water will remain in the tank.

A. For how may miles is the rental cost at both companies the same?
B. What is that cost?
Explain both part A and part B!
Answers
r1 + g1 + 0.25m = r2 + g2 + 0.35m now plug in and solve for m
40 + 15 + 0.25m = 45 + 0.35m
55 - 45 = 0.35m - 0.25m
10 = 0.1m
100 = m
for 100 miles the cost will be the same
now to find the cost
0.25m plug in 100 for m
0.25(100) = 80
for the course of 100 miles the cost will be $80

What is Graph?There are many tools we can use to find the information of the relation which was used to form the graph.
A graph contains data of which input maps to which output.
Analysis of this leads to the relations which were used to make it.
The slope-intercept form of the equation of a line; y=mx+b,
where m is the slope and b is the y-intercept(value of y at x =0)
Since, slope = (y - y')/(x -x')
In our case,
b = 3
Slope = (-3-0)/(0-6)
Slope = -2
thus, the equation of line will be written as:

Wally is playing with his toy robot. The robot's battery is 80% full when he starts playing with it. The battery drains to 74% after Wally plays with the robot for 40 minutes. If t represents the time elapsed in minutes and l represents the battery level, which of the following equations can be used to model this situation?
A. l = -0.15 + 80t
B. l = -0.15t + 80
C. l = 80t + 0.15
D. l = -0.15t - 80
Answers
For your question
Answer:
B. l = -0.15t + 80
Step-by-step explanation:
From the options we can see that the relation between the battery level (I) and the time elapsed (t) is modeled by the equation of a line, that is:
I = a*t + b
where a and b are some constants, I is in % and t is in minutes.
At t = 0 (when Wally starts to play) the battery is 80%, that is:
80 = a*0 + b
80 = b
At t = 40 minutes the battery is 74%, then:
74 = a*40 + 80
74 - 80 = a*40
-6 = a*40
-6/40 = a
-0.15 = a
Then, the equation is I = -0.15*t + 80
A computer store bought a program at a cost of $10 and sold it at a selling price of $12. Find the percent markup.
PLEASEEEE
Answers
The percent markup on a program bought for $10 and sold for $12 is 20%.
Explanation:The question you've asked relates to the calculation of percent markup on an item. In this case, a computer store purchased a software program for $10 and sold it for $12. To find the percent markup, we compare the markup to the cost price. The markup here, is the difference between the selling price and the cost price which is $12 - $10 = $2. To find the percent markup, you divide markup by the cost price and then multiply by 100 to get a percentage. So, the calculation is ($2 / $10) × 100, which equals 20%.
