3 times 10 is 30, 7 times 10 is 70. There are 30 girls and 70 boys.
Answer:
10
Step-by-step explanation:
AC = CB
6a - 8 = 4a - 2
a = 3
6(3) - 8 = 10
AC = 10
Answer:
a= 30
b=60
c=105
Step-by-step explanation:
A forms a vertical angle with another angle that measures 30 degrees, therefore,
a= 30 degrees.
Since a is 30 degrees and a and b are in the same triangle with a 90-degree angle and all interior angles in a triangle equal 180 degrees.
Then, 30+90+b=180
120+b=180
b=60
Angle c and an angle that equals 75 degrees are supplementary. meaning that they add up to 180 degrees.
180-75=c
105=c
Step-by-step explanation:
all you have to doe is type Ex:4 into the calculator and you should get your answer.
A = 3.141 * (3km^2). Just put that into a calculator and bingo
