The answer would be A) 2,640.

In order to find this we must first find an amount of people per square feet. Since we are given that 10 people fit in a 5x5 square, we know that 10 people fit in 25 square feet. This will be the basis for our final calculation.

Now we need to find how many square feet we have. Since it is a quarter of a mile long, we'll divide the number of feet in a mile by 4.

5,280/4 = 1320.

Now we take the length and multiply it by the width, which is 5ft.

1320 * 5 = 6,600 square feet.

So we now know the size of the crowd. We can use that and multiply it by the factor that we found at the start to find the number of people.

6,600 square feet * 10 people/ 25 square feet = 2,640 people.

Answer:

A. m^2+7m+10=0

Step-by-step explanation:

This is a problem in pattern matching, and in substituting a variable for a pattern.

(x^2+3)^2 +7x^2 +21 = -10 . . . . . . given

(x^2 +3)^2 +7(x^2 +3) = -10 . . . . . factor the last two terms

m^2 +7m = -10 . . . . . . . . . . . . subsitute m for x^2 +3

m^2 +7m +10 = 0 . . . . . . . . add 10 to both sides; matches A

Fareed wants to add 1/4 +5/8 Add the fractions by using the giant one to create a common denominator

saul85 [17]

Hi!

This question is about math.

$\frac{1}{4}+\frac{5}{8}$

Least Common Factor 4 or 8: 8

Factors of 4 : 1, 2, 4 (prime factorization) (2*2)

Factors of 8: 1, 2, 4, 8 (prime factorization) (2*2*2)

Least Common Factor of a,b is the smallest positive number that divisible by both a and b.

Multiply each factor the greatest number of times it occurs in either 4 or 8.

Then multiply by the numbers.

$2*2*2$

$=8$

Multiply each numerator by the same amount needed to multiply its corresponding denominator to turn it into the Least Common Factor of 8.

For 1/4 multiply the denominator and numerator by the 2.

$\frac{1}{4}=\frac{1*2}{4*2}=\frac{2}{8}$

$\frac{2}{8}+\frac{5}{8}$

Since the denominator are equal, combine the fractions.

$\frac{2+5}{8}$

Add the numbers 2+5=7

$=\frac{7}{8}$

Hope this helps! Thank you for posting your question at here on Brainly. Have a great day.

Use the equation below to find y, if m= 8 and x=6. y=mx y=?

Lunna [17]

Answer:

The value of y is 48.

Step-by-step explanation:

You have to substitute the values into the equation :

$y = mx$

$let \: m = 8,x = 6$

$y = 8 \times 6$

$y = 48$
