On a flight from New York to London, an airplane travels at a constant speed. An equation relating the distance traveled in miles, d, to the number of hours flying, t, is LaTeX: t=\frac{1}{500}dt=1500d. How long will it take the airplane to travel 800 miles?
Answer:
1.6hours
Step-by-step explanation:
We know that Speed= distance/ time
But from the question, An equation relating the distance traveled in miles d to the number of hours flying t is t= 1/500d.
And the distance is given as 800 miles
Then, what we need is to substitute the given Distance into the equation of time.
t= 1/500d. Where d= 800 miles
t= (1/500) × 800 miles
t= 800 miles/500
t= 1.6hours
Hence, it will take the airplane to travel 800 miles , 1.6hours
Which of Talia's steps is incorrect? Step 1 is incorrect because it uses a point that is not on the line. Step 2 is incorrect because it uses a point that is not on the line. Step 3 is incorrect because it shows an incorrect ratio for the slope. Step 4 is incorrect because it shows an incorrect substitution of (1, 3) into the point-slope form.
Answer:
Step 3 is incorrect because it shows an incorrect ratio for the slope.
Step-by-step explanation:
The correct question is:
Talia wants to write the equation of the graphed line in point-slope form. These are the steps she plans to use:
Step 1: Choose a point on the line, such as (2, 5).
Step 2: Choose another point on the line, such as (1, 3).
Step 3: Count units to determine the slope ratio. The line runs 1 unit to the right and rises 2 units up, so the slope is .
Step 4: Substitute those values into the point-slope form.
y – y1 = m(x – x1)
y – 3 = (x – 1)
Which of Talia’s steps is incorrect?
Step 1 is incorrect because it uses a point that is not on the line.
Step 2 is incorrect because it uses a point that is not on the line.
Step 3 is incorrect because it shows an incorrect ratio for the slope.
Step 4 is incorrect because it shows an incorrect substitution of (1, 3) into the point-slope form.
Answer:
Step 1 is correct because from the graph, points (1,3) and (2,5) lies on the line so the points can be used to find the slope.
Step 2 is also correct.
Step 3 is incorrect. Slope of a graph is the ratio of vertical change to horizontal change. The vertical change is the rise while the horizontal change is the run, hence slope is the ratio of rise to run.
Since the line runs 1 unit to the right and rises 2 units up, so the slope is 2/1 = 2
Therefore the correct point-slope form is:
y – y1 = m(x – x1)
y – 3 = 2(x – 1)
Step 4 is correct, because i t shows an incorrect substitution of (1, 3) into the point-slope form.

slope=(11-9)÷(4-3)
slope= 2.
Answer:
slope=∆y/∆x
thus any values of x and y in the table can be used.

The number of hours, H, that milk stays fresh is a function of the surrounding temperature, T. In degrees centigrade, this relationship is shown by the formula H(T) = 180 ∙ 10(−.04T) . How many hours will newly pasteurized milk stay fresh when stored at 8°C?
Answer:
The number of hours that the milk will stay fresh is 86.2 hours
Step-by-step explanation:
Given the following function;
[tex]H(T) = 180*10^{(-0.04T)}[/tex]
where;
T, is the temperature in degrees centigrade
H is the number of hours
At 8°C the number of hours that the milk will stay fresh is given by;
[tex]H(T) = 180*10^{(-0.04T)}\\\\H(8) = 180*10^{(-0.04*8)}\\\\H(8) = 180*10^{(-0.32)}\\\\H(8) = 180*0.4786\\\\H(8) = 86.2 \ hours[/tex]
Therefore, the number of hours that the milk will stay fresh is 86.2 hours.

Martene put 3885\text{ cm}^33885 cm 3 3885, start text, space, c, m, end text, cubed of water in the aquarium. How deep is the water in the aquarium? \text{ cm} cm
Answer:
[tex]Depth = 14[/tex]
Step-by-step explanation:
Given
[tex]Length = 18.5cm[/tex]
[tex]Width = 15cm[/tex]
[tex]Volume = 3885cm^3[/tex]
Required
Determine the deep of the aquarium
Volume is calculated as thus:
[tex]Volume = Length * Width * Depth[/tex]
Substitute values for Volume, Length and Width
[tex]3885 = 18.5 * 15 * Depth[/tex]
[tex]3885 = 277.5 * Depth[/tex]
Solve for Depth
[tex]Depth = 3885/277.5[/tex]
[tex]Depth = 14[/tex]
Hence;
the depth is 14cm

Abraham has visited country somebody he has a cold or visiting at least 50 countries he plans to choose a school by visiting five new countries per year (Y) for the next several years which inequality and solution shows the amount of years they will take for Abraham to meet his goal
Question:
Abraham has visited at least 50 countries; he plans to visit five new countries per year (Y) for the next several years. Which inequality and solution shows the amount of years they will take for Abraham to meet his goal.
Answer:
[tex]Countries \geq 50 + 5y[/tex]
[tex]y \leq 29[/tex]
Step-by-step explanation:
Given
[tex]Countries = 50[/tex] ------ at least
[tex]Yearly =5[/tex]
Required
Represent as an inequality
"at least" means [tex]\geq[/tex]
So the countries he has visited can be represented as thus;
[tex]Countries \geq 50[/tex]
If
1 year = 5 countries
y years would be 5y countries
So, in y years; he'd have visited
[tex]Countries \geq 50 + 5y[/tex]
To determine the value of y.
We have that
[tex]Countries = 195[/tex] in the world
Substitute 195 for Countries
[tex]195 \geq 50 + 5y[/tex]
Collect Like Terms
[tex]195 - 50 \geq 5y[/tex]
[tex]145 \geq 5y[/tex]
Divide through by 5
[tex]145/5 \geq y[/tex]
[tex]29 \geq y[/tex]
Reorder
[tex]y \leq 29[/tex]
This means that; he'll visit all countries in at most 29 years' time
A mobile dealer sells a mobile at a discount of 25% on its marked price and earns a profit of 10%. If the marked price of the mobile is 8800, what will be the cost price of the mobile? 6075
Discount = 25% .
Profit = 10%.
Marked price of mobile = Rs.8800.
Find :Cost Price of the mobile
Solution :As we know that, their is no direct relation between Mark price and cost price . so we have to work on selling price of the mobile.
So,
→ MP of mobile = Rs.8800
→ Discount = 25% .
than,
→ SP of mobile = MP * (100 - discount%) / 100
→ SP of mobile = 8800 * (100 - 25) / 100
→ SP of mobile = 88 * 75
→ SP of mobile = Rs.6600 .
Now,
→ SP of mobile = Rs.6600
→ Profit % = 10% .
than,
→ CP of mobile = SP * 100 / (100 + Profit%)
→ CP of mobile = 6600 * 100 / (100 + 10)
→ CP of mobile = (6600 * 100) / 110
→ CP of mobile = 60 * 100
→ CP of mobile = Rs.6000 . (Ans.)
Hence , Cost Price of the mobile is Rs.6000.
I hope it will help you.

A percentage is a way to describe a part of a whole. The cost price of the mobile phone is 6,000.
What are Percentages?A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.
Let the cost price of the mobile be represented by x.
Given that dealer earn profit of 10% on its cost price, therefore, we can write the selling price of the mobile as,
Selling price = Cost price + Profit
= x + 10% of x
= 1.10x
Also, given that the mobile dealer sells a mobile at a discount of 25% on its marked price. Therefore, we can write the selling price as,
Selling price = Marked price - Discount
= Marked price - 25% of marked price
= 8,800 - 25% of 8,800
= 8,800 - 0.25(8,800)
= 8,800 - 2,200
= 6,600
Now, Comparing the sales price we got from above two equation, therefore, the cost price of the mobile can be written as,
1.10x = 6,600
x = 6,600/1.10
x = 6,000
Hence, the cost price of the mobile phone is 6,000.
