Aaron, Blaine, and Cruz are solving the equation
Which of the following is true?
Blaine and Cruz made an error in picking their first
steps
Cruz made an error in picking his first step
All three made an error because the right side
Aaron started his solution by multiplying both sides
of the equation by a
Blaine started by using the distributive property to
multiply by both 7 and -n.
Cruz started by dividing both sides of the equation
by
gyals - 1
All three chose a valid first step toward solving the
equation

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units

step-by-step explanation:

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
