Marsha recorded the time it took seven children of different ages to run one lap around the track.
Using the line of best fit, which is closest to the length of time it should take Marsha's 6 year old niece to
run one lap?
A. 190
B. 200
C. 205
D. 210
Answers
Reasoning: There is a 40s difference between the age of 4 and 8 meaning 6 most likely would be in the center of that, which also means it’d be about half of 40. So with that we subtract 20 from 225 and thus giving us the closest length of time it should take Marsha’s 6 year old niece to run one lap, 205s.

The selling price of an item is $480. It is marked down by 10%, but this sale price is still marked up from the cost of $360. Find the markup from cost to sale price.
Answers
Answer:
72
Step-by-step explanation:
i just know it
If the selling price of an item is $480. It is marked down by 10%, but this sale price is still marked up from the cost of $360.Then 72 is the markup from cost to sale price
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
Given,
The selling price of an item is $480
It is marked down by 10%, but this sale price is still marked up from the cost of $360
We need to find 10% of 480
10/100=0.1
0.1×480=48
48 is the 10% of 480
Now subtract 48 from 480
480-48
432
Now subtract 360 from 432
432-360
72
Hence 72 is markup from cost to sale price

The volume V of gas varies inversely to the pressure P. The volume of a gas is 200 cm3 under pressure of 32 kg/cm2. What will be its volume under pressure of 40 kg/cm2?
Answers
Answer:
V = 160 cm³ when P = 40 kg/cm²
Step-by-step explanation:
V = k / P
Where,
V = volume
P = pressure
k = constant of proportionality
The volume of a gas is 200 cm3 under pressure of 32 kg/cm2
V = k / P
200 = k / 32
Cross product
200 × 32 = k
6,400 = k
k = 6,400
What will be its volume under pressure of 40 kg/cm2?
V = k / P
= 6,400 / 40
= 160
V = 160 cm³

An airplane flying at an altitude of 2600 m is approaching an airport run away located 56 km away (from the airplane to the run away). Calculate the airplane’s angle of decent. (Hint: the angle of decent is the same as the angle of depression.)
Answers
Given :
An airplane flying at an altitude of 2600 m is approaching an airport run away located 56 km away.
To Find :
The airplane’s angle of decent.
Solution :
Height of plane, h = 2600 m.
Horizontal distance of airplane from vertices is, d = 56 km = 56000 m.
Let, angle of depression is Ф.
So,
[tex]tan \ \phi = \dfrac{56000}{2600}\\\\tan \ \phi = 21.54\\\\\phi = 87.34^o[/tex]
Therefore, the angle of decent is 87.34°.
Hence, this is the required solution.

Sylvia plans to place 617 stamps in an album. Each page of the album holds 5 stamps. She uses division to find out how many full pages she will have. How many full pages will she have?
Answers
Answer:
123 full pages
Step-by-step explanation:
Given
[tex]Total\ Stamps = 617\ stamps[/tex]
[tex]Each\ Page = 5\ stamps[/tex]
Required
Determine the number of full page
To do this, we simply divide the total stamps by stamps in each page;
[tex]Pages = \frac{Total\ Stamps}{Each\ Page}[/tex]
[tex]Pages = \frac{617}{5}[/tex]
[tex]Pages = 123.4[/tex]
Then we record only the quotient
The quotient is the digits before the decimal
[tex]Pages = 123[/tex]
Hence, she has 123 full pages

If in the 1980's about 60 million families had Tv's in their homes and in 2015 there was almost 100 million families that had Tv's in their home how many more Tv's were there in 2015?
Answers
Answer: 40 million
Step-by-step explanation:
Number of families that had TVs in their home in 1980s = 60 million
Number of families that had TVs in their home in 2015 = 100 million
To calculate the increase in TVs that were there in 2015, we subtract the number of families that had TVs in their home in 1980s which was 60 million from the number of families that had TVs in their home in 2015 which was 100 million. This can be expressed as:
= 100 million - 60 million
= 40 million

What is the answer to the questions A. B. C. ?? Please help this is a summative
Answers
Answer:
A) 12.5 per hour. Slope: y = 12.5x
B)500x or Next - Now = 500x = 1,360
C) y = 12.5 + 360
Step-by-step explanation:
A) 360 in account, 40 hour then she has 860.
Find the unit amount so to find how much she gets per hour you have to find the unit amount.
Since she had a total of 860 but she already had 360, subtract 860 - 360 = 500. Now divide by 40: 500/40 = 12.5. (that's how much she gets per hour.)
B) Next , Now
Next she will make 500 every 40 hours so after that she'll have 1.360 in her account.
Equation: Next,Now
So it's the rate of change which will be 500 per 40 hours. so the rate of change is 500x
C) equation:
Rate of change 12.5 per hour
Y- intercept is 360 since that's what she had in her account so,
y = 12.5x + 360

Every ride at the country fair costs the same amount. The cost of one ride is $2.25. The fair entry fee is $6.50. Lupe paid the entrance fee and rode 7 rides. How much did Lupe pay in all?
Answers
Answer:
$22.25Step-by-step explanation:
Step one:
given data
we are told that the cost of one ride is $2.25
the entry fee= $6.5
the linear function for the situation is represented by the equation of line
y=mx+c
Step two:
let x be the number of ride
given that x=7
substituting we have
y=2.25(7)+6.5
y=15.75+6.5
y=22.25
In all Lupe we have to pay $22.25
