Answer:
1) c/d = pi
Step-by-step explanation:
since c= pi x d
divide both sides by d
c/d = pi

Answer:
He worked 8 hours overtime.
Step-by-step explanation:
A man was paid per hour up to 40 hours = $3.00
He was paid for 40 hours = 40 × 3 = $120
He did overtime, for which he was paid twice of the regular payment = 2(3)
= $6.00
He was paid for his overtime = 168 - 120 = $48.00
His overtime payment per hour = $6.00
He did overtime = 48 ÷ 6 = 8 hours
He worked 8 hours overtime.
a. Why is her conclusion not valid?
Answer:
She painted her sister's nails with Brand B, not her own nails.
Step-by-step explanation:
All parts to an experiment must be the same except one thing. She is testing different nail polishes so that's what needs to be different. By painting her hand with one nail polish and her sister's with the other, she is changing a second variable in the experiment making it invalid.
The measure of angle ABC tangent chord angle is 117°.
Tangent of a circle is defined as the line that passes through exactly one point on the circle.
Chord is the line segment that has it's two end points on the circle.
A chord AB is drawn.
AXB is one of the arc which measures 234°.
We have to find the angle that a tangent through B makes with chord AB.
This measure will be half of the arc measure.
Angle ABC = 234° / 2 = 117°
Hence the measure of the angle ABC is 117°.
