Answer:
The angles m∠Q and m∠S together equal 90°
Step-by-step explanation:
A right angle measures 90°.
The total measure of angles in a triangle sums to 180°.
This gives us:
m∠Q + m∠S + ∠R = 180°
m∠Q + m∠S + 90° = 180°
Rearranging yields:
m∠Q + m∠S = 180° - 90°
m∠Q + m∠S = 90°
Class B exhibits the most consistent sleep patterns since there's a smaller variance between 6.87 and 3.65 compared to the other classes.
Answer:
The least quantity of water needed to fill the sphere is 
Step-by-step explanation:
We know that
The volume of the sphere (the glass sphere) can be defined as
We have
----> the radius equals half the diameter
Let’s assume
Now substitute
Calculating the number: 1 group of ten plus 16 units equals 1×10 plus 16×1, which is 10 plus 16, totaling 26.
Hope this clarifies things!
Calculating the new cost, first, determine 8% of $12.95 which equals $1.036. Adding this to the original price gives $13.986. Then, multiply $13.986 by 4 to get $55.944. Finally, apply a 10% discount which results in $50.3496, rounding up gives $50.35 for four CDs this year.
