Answer:
The least number of stamps required is
Step-by-step explanation:
Let the number of cent stamps be and cent stamps be
We have
The minimum number is obtained when more cent stamps are used
Here cannot be greater than since
Substitute
Not possible since is not a fraction
Substitute
Not possible since is not a fraction
Substitute
Possible
Hence minimum number of stamps is
$8250 - $3120 = $5130
$5130/75 = $68.40
Each band member must raise $68.40
Answer:
sqrt(2)/2
Step-by-step explanation:
Sin(135) = sin(180-135) = sin(45)
= 1/sqrt(2) or sqrt(2)/2
sqrt: square root
BCGF is a quadrilateral, angles sum to 360 degrees.
B+C+G+F=360
B and G are right angles, formed by a radius and a tangent.
90+C+90+F=360
C+F=180
C and F are supplementary.
2x + 146 + 4x + 238 = 180
6x + 384 = 180
6x = -204
x = -34
Answer: -34, second choice
