There are 750 spectators of which of 420 are women and the rear are men what percent of the spectators are women
andrew-mc [135]

Answer: 56%

Step-by-step explanation:

There are 750 total people in this crowd.

420 are women and their percentage of the total is needed.

You get this by dividing the number of women by the total number of spectators and then multiplying by 100%:

= Number of women/ Total people * 100%

= 420 / 750 * 100%

= 56%

Smithville is 30 miles due south of Jonestown, and Brighton is 72 miles due east of Smithville. What is the distance from Jonest
Alekssandra [29.7K]

Answer: 78 miles

Step-by-step explanation:

Hi, since the distances form a right triangle ( see attachment) we have to apply the Pythagorean theorem:

c2 = a2 +b2

Where c is the hypotenuse (the longest side) and a and b are the other two sides of the triangle.

In this case the hypotenuse is the distance from Jonestown to Brighton (x)

Replacing with the values given:

x2 = 30^2 + 72 ^2

x2 = 900+5184

x2=6084

x = √6084

x = 78 miles
