Answer:
there are two solutions:
a) 
, and
b) 
Step-by-step explanation:
In the equation: 
, since a perfect square with the unknown "y" is isolated on the left of the equal sign, we start by applying the square root on both sides of the equality, and then on isolating the unknown:
Therefore there are two solutions:
a) , and
b)
G is correct.
(12+34+27+27+36+42+15+28+32+47+30):11=30
The mean is 30.
Answer:
x=3, y=4
Step-by-step explanation:
Answer:
arc QS = 95°
Step-by-step explanation:
the inscribed angle QSR is half the measure of its intercepted arc RQ , then
arc RQ = 2 × 95° = 190°
the sum of the arcs in a circle = 360° , then
arc QS = 360° - arc SR - arc RQ = 360° - 75° - 190° = 95°
Answer:
The volume of the box would be 0.001463 cubic meters
Step-by-step explanation:
You first have to to do the conversion from cubic milimiters to cubic meters using the rule given. A cubic milimiter is only 1^3 = or 1*1*1. We transform then this rule so it applies for cubic measures.
1 millimeter = 0.001 meter
(1 millimeter)^3 = (0.001 millimeter)^3 (raise to the cubic power)
1 cubic milimiter = (0.001*0.001*0.001) cubic meters= 0.000000001 or 1 * 10^-9 in scientific notation.
Then we us a rule of three as follows
1 cubic millimiter / 1 * 10^-9 cubic meters =1,463,000¨cubic milimiters / x cubic meters
x = 1,463,000*1 * 10^-9= 0.001463 cubic meters
