Answer:
c = 24.34
Step-by-step explanation:
Here, we can use the cosine rule
Generally, we have this as:
a^2 = b^2 + c^2 - 2bcCos A
12^2 = 14^2 + c^2 - 2(14)Cos 19
144 = 196 + c^2 - 26.5c
c^2 - 26.5c + 196-144 = 0
c^2 - 26.5c + 52 = 0
We can use the quadratic formula here
and that is;
{-(-26.5) ± √(-26.5)^2 -4(1)(52)}/2
(26.5 + 22.23)/2 or (26.5 - 22.23)/2
24.37 or 2.135
By approximation c = 24.34 will be correct
The probability that his number will be 4 is one in eleven, or 1/11.
Circumference = πD
πD = 56.52
D = 17.99 in
Area of the pizza = π (17.99 ÷ 2)² = 254.19 in²
Area of the pizza eaten = 254.19 ÷ 4 = 63.55 in²
Area of the pizza remain = 254.19 - 63.55 = 190.64 in²
Answer: 190.64 in²
Answer:
C
Step-by-step explanation:
Ok so for this problem you you divide 2/3 n by 2/3 and 7/8 by 2/3
you get

to divide fraction you flip the divider over to find the reciprocal
2/3 > 3/2 also you change the division symbol to the multiplication symbol
the equation now is

now you multiply to get 21/16
the answer is 1 5/16 after you simplify it
