Philip and Barbara are 8 meters apart because 5+3=8 so it will make 8 meters
Answer:
Step-by-step explanation:
EVEN THOUGH IT SHOWS A 1 DEGREE TEMPERATURE RISE AT 4PM TO 66
THAT SHOULD NOT MATTER IT FELL A TOTAL OF 5 DEGREES FROM 3 TO 6PM
Use Pythagorean Theorem:
a² + b² = c²
"a" is one side of the right triangle.
Its length is: radius of larger circle minus radius of smaller circle: (11 - 3 = 8)
The distance between the center of the circles creates the hypotenuse (17)
8² + b² = 17²
b² = 225
b = 15
Answer: the length of the common external tangent is 15.
Answer:
x = w / (56 + r)
Step-by-step explanation:
Given the equation :
19x + rx= -37x + w ; find x
Collecting like terms
19x + rx + 37x = w
Factorizing x in the Left hand side
x(19 + 37 + r) = w
x(56 + r) = w
Therefore we can obtain x by dividing both sides by (56 + r)
x(56 + r) / (56 + r) = w / (56 + r)
x = w / (56 + r)
