A pair of angles whose sum is 90 degrees are called Complementary Angles.
Hope this helped you :)
Answer:
C
Step-by-step explanation:
The cakes which overlap are the small and middle & the middle and large. The total area of overlap for these cakes will be the surface of the smallest layer's base plus the surface of the middle layer's base.
We can find the area by
where r is radius which is half the diameter.
Smallest cake - D=7.5, so r=3.75
=10.5625 × π = 33.1830724035 or 33.2
Middle Cake - D=10, so r=5.
=25 × π = 78.5398163397=78.5
We add together 33.2+78.5= 111.7 cm squared
C is the closest.
Step-by-step explanation:
x2 + bx +5 = 0,
where a,b and c are rational numbers.
Also it is given that the quadratic has 2 distinct zeros and one of it's zero is irrational.
We know that if it has a one irrational zero, the conjugated couple of the one zero is also a null with the same polynomial balance for a polynomial equation with rational coefficients." Therefore, in this case it is a quadratic equation, one is null and irrational; thus, the other zero is irrational.

B = 655.096 + 9.563W + 1.85H - 4.676A W = 55 A = 70 H = 172 now we sub B = 655.096 + 9.563(55) + 1.85(172) - 4.676(70) B = 655.096 + 525.965 + 318.2 - 327.32 B = 1499.261 - 327.32 B = 1171.941 1171.941 - 1000 = 171.941 rounds to 172 answer is B. 1000 calories is not sufficient, it is 172 calories short
