Answer:
5 boys to 9 girls
Step-by-step explanation:
Let x = the number of boys
Boys = x
Girls = x + 4
x + (x + 4) = 14
2x + 4 = 14
2x = 10
x = 5
This means that there are 5 boys. Since girls = x + 4, 5 + 4 = 9. There are 5 boys and 9 girls.

Answer:
A. 23 in.
Step-by-step explanation:
Let r represent the radius of the circular disc.
We have been given that a circular disc has an area that measures between 1,650 and 1,700 square inches.
We will use area of circle formula to solve our given problem.
, where r represents radius of circle.
Since the area of given disc is between 1650 and 1700 square inches, so we can set an inequality as:
Dividing our inequality by 3.14 we will get,
Upon taking square root we will get,
Since 23 is between 22.9233 and 23.268031156, therefore, the length of radius of the given disc could be 23 inches and option A is the correct choice.
Answer:
100 cm
Step-by-step explanation:
Given:
AC = BC
AC = 40
2AB=AC
Simplify:
BC = 40
Simplify:
2AB = 40
Algebra:
AB = 20
Here's the sides:
AB = 20
AC = 40
BC = 40
Add all of them together:
100

Answer:
A) ≈22.4 concert attendees might have left early.
B) 605 attendees might leave early.
Step-by-step explanation:
A) 11/100, or 11%, of the sample left early.
11% of all the concert attendees is (11/100) × 2040 ≅ 22.4
attendees who might have left early.
B) 11% of the total attendance is 11% × 5500 = 605 attendees who might
leave early.
