Answer:
27
<em><u>OR</u></em> 84.78
Step-by-step explanation:
find the area using the formula 
and multiply it by 
because it is three fourths of a circle
Answer:
Step-by-step explanation:
Let the first number = x
Let the second number = x + 9
Let the third number = 4x
Together they make 123
x + x + 9 + 4x = 123 combine the left
6x + 9 = 123 Subtract 9 from both sides
6x = 123 - 9
6x = 114 Divide by 6
x = 114/6
x = 19
=================
First number = 19
Second number = 19 + 9 = 28
Third number = 4*19 = 76
Answer: 3/4
Step-by-step explanation:
Number of students in Jacob's homeroom = 20.
Number of students who bring their lunch to school = 5
Since the rest eat lunch in the cafeteria, the number of those who eats in the cafeteria will be:
= 20 - 5
= 15
Fraction that eats in the cafeteria will be: = 15/20 = 3/4
Answer:
definition the set of positive real number which greater than 0 are the nonnegative number. for ex=(1,2,3...10)
Discriminant D is given by:
D=b²-4ac
Implication of discriminant is as follows:
D<0 two zeros that are complex conjugate
D=0 one real zero of multiplicity 2
D>0 two distinct real zers
D= (+ve perfet square) two distinct rational zeros
From:
12x^2+10x+5=0
plugging in the equation we get:
10²-4×12×5
=100-240
=-140
thus
D<0
