The size of the crowd is 21,120 standing along a 1 mile section of a parade route that is 10 feet deep on both sides of the street.
How much 1 mile into feet?A mile is a unit of distance equal to 5,280 feet or exactly 1.609344 kilometers.
Given
The size of a crowd standing along 1 mile section of parade route that is 10 feet deep on both sides of the street assume that each person occupies 2.5 square feet.
1 miles is equal to 5280 feet thus,
[tex]\rm= 5280 \times 10\\\\= 52800[/tex]
Divide this by the amount of space a person takes up
[tex]= \dfrac{52800 }{ 2.5}\\\\ = 21120[/tex]
Hence, the size of the crowd is 21,120 standing along a 1 mile section of a parade route that is 10 feet deep on both sides of the street.

When Rafiq left home on a business trip
he noted that the odometer on his car
read 47,823. He drove 3 h 15 min and
then noted that the odometer read
48,017. Find his average speed in miles
per hour.
Answers
He travelled : 48017 - 47823 = 194 (miles)
15 mins = 1/4 hours => 3h 15min = 3 1/4 hours = 13/4 hours
So, he travelled at an average speed of 194 : 13/4 = 59 (miles/h)

Answer:
1:5 4:20
Step-by-step explanation:
Because say you got 1 right out of 5 on test you get a 20%
since 20 can go into a 100 5 times if whatever number is the 1rst time it can go into 5 it is a 20 like 4:20 because 4,8,12,16,20 see that's 5 numbers and 4 is the first.
In then 1:5 is another example it can go 5 times or one more is like 10:50=20% or 15:75.

Which quadratic function in vertex form has a vertex at (-2, 6) and passes through the point (-4, 8)?
A. y = 1/2 ( x - 2 ) ^2 + 6
B. y = -1/2 ( x - 2 ) ^2 - 6
C. y = -1/2 ( x - 2 ) ^2 + 6
D. y = 1/2 ( x + 2 ) ^2 + 6
Answers
Answer:
y = -1/2(x + 4)² + 2 or y = -1/2x²- 4x - 6
Step-by-step explanation:
Given
Vertex = (-4, 2)
The graph passes through the point (-8, -6)
The function in vertex form is:
y = a(x + 4)² + 2
Substitute the coordinates of (-8, -6) and find the value of a:
-6 = a(-8 + 4)² + 2
-8 = 16a
a = -1/2
The function is:
y = -1/2(x + 4)² + 2
or in standard form:
y = -1/2(x² + 8x + 16) + 2 = -1/2x²- 4x - 6

What is an equation of the line that passes through the points (-8, 1) and(7,1)?
please help im giving 20 points to who ever answers it
Answers
Answer:
y=1
Step-by-step explanation:
you can use those points to find the slope
use the equation [tex]\frac{y_{1} - y_{2}}{x_{1}-x_{2}}[/tex] then plug in the numbers
so (1-1)/(-8-7) = 0/15 so the slope is zero meaning it is a horizontal line which we can tell logically because the y coordinates of both points are 1.
so if you plug those numbers into the formula y=mx+b where m is slope and b is the y intercept then
you get y=0*x+1
then 0*x is just zero and it goes away so the equation for this line is y=1
Hope this helps! :)

if the least value of n is 5, which inequality best shows all the possible values of n?
n ≥ 5
n ≤ 5
n < 5
n > 5
Answers
Answer:
First option
Step-by-step explanation:
The inequality says greater than or equal to 5. Which means n is greater than or equal to (≥) 5.
It's not the second option because less than or equal to means that n is less than or equal 5, which doesn't check out since 5 is the smallest value of n.
It's not the third option since it says that 5 is greater than n, when we know that one of n's values is 5.
It's not the fourth option since it says that that n is greater than 5, when we know again that one of the values of n is 5.
Your answer is the first option "n ≥ 5."
