Answer:
D. 6 7/8
Step-by-step explanation:
First, convert 2 3/4 to an improper fraction.
2 times 4 = 8
8+3=11
11/4 ÷2/5
Then, flip the second fraction and change the sign to multiplication.
11/4 × 5/2
Multiply.
11 × 5 = 55
4 × 2 = 6
55/6
Simplify the fraction.
6 7/8
x:14 = 7:8
x:14 = x/14
7:8 = 7/8
x/14 = 7/8
Multiply the numerator of the 1st ratio with the denominator of the 2nd.
And multiply the numerator of the 2nd ratio with the denominator of the 1st.
Doing so, we get -
x * 8 = 7 * 14
So, 8x = 7 * 14
8x = 98
We divide 98 by 8 (transposition method)
x = 98/8
Therefore, x = 12.25
ANSWER:
r = 
Explaination:
Convert the given curve into the the polar form.
x = rcosθ
y = rsinθ
in f(x,y) = (x²-y²) - √(x²+y²) = 0
put the values of x & y in given curve equation.
We get at,
g(r,θ) = (r²cos²θ - r²sin²θ) - √(r²cos²θ + r²sin²θ) = 0
g(r,θ) = r²(cos²θ - sin²θ) - √r² = 0
We know that,
cos²θ - sin²θ = cos2θ
g(r,θ) = r²(cos2θ) - r = 0
Solve for r
Finally we get:
r =
You would just take .5x5 which would be 2.5 inches without the snow melting it would add up to 13.5in the last part with the tt I’m not sure but it follows the same principle .5x(Time)+the original amount will give you the answer
