Answer:
$24
Step-by-step explanation:
James and Sarah's lunches cost $20 each, so the total price of their meal is 20 * 2 = $40.
They tipped their server 20% of $40, so to find 20% of 40 you would multiply:
40 * 0.20 = 8
Add 8 to 40 = $48.
If they shared this lunch price of $48 equally then they each paid half of this price.
48 / 2 = 24
They each paid $24.
Rationals are whole numbers no negative numbers or decimals or fractions and Intergers are only negativd numbers. Absolute Value is a negative number changed into a whole number. Hope this helps.
Answer:
C= 38 in Approx
A=113 in^2 Aprprox
Step-by-step explanation:
Given data
radius= 6 ft
Circumference, C=2πr
substitute
C=2*3.142*6
C=37.704 in
Area A= πr^2
substitute
A=3.142*6^2
A=3.142*36
A=113.112 in^2
If the center is (0, 0), then there is no side to side or up or down motion. The center is at the origin. The standard form of a circle is (x-h)^2 + (y-k)^2 = r^2. Your h and your k are both 0's, so just fill in and square the radius:
x^2 + y^2 = 64
The labeled angle is what's called an inscribed angle. There's a theorem (fittingly called the inscribed angle theorem) that says the measure of this angle is half the measure of the circular arc that it subtends.
In this case, the angle is subtended by an arc measuring 180°. So
(4x + 6)° = 1/2 • 180°
4x + 6 = 90
4x = 84
x = 21
