8.50 * 9.333333 * 12.40
answer is 983 (11/15)
Answer:
(1) 9
(2) 
(3) 6()
Step-by-step explanation:
From the question,
(1) (
)²
Applyin the law of multiplication of surds
()² = (
(2) (
)× (
) =
Also applying the the law of multiplication of surd
(
)×() = () ( This is an irational answer)
∴ ()×() =
(3) 2()×3()
Also applying the law of multiplication of surds i.e Multiply surds to surds and whole number to whole number
= 2×3×()×()
6×() = 6(
let's put value of t in equation.
x = 2√t
x = 2√y
x/2 = √y
(x/2)^2 = y
y = x^2 /4
now let's differentiate it with respect to x.
dy/dx = 2x/4 = x/2
differentiating again wrt to x
d^2y/dx^2 = 1/2
A) 25x+15y=650
25x+15(40)=650
Or it could be 25x=650 and 15y=650
B) No because she makes $15 for every necklace which she only has 40 necklaces 15x40=600
Answer:
$130.68
Step-by-step explanation:
1 acre = 43,560 square feet
3/4 of 43560 = 32,670 (So that would be 76,230 sq ft in 1.75 acres because 43560 + 32670 = 76230)
We need to divide the total by 35 plots.
76230 / 35 = 2178, using long division.
2,178 square feet is just one plot of 35. We need to multiply 2178 by 0.06.
Answer: $130.68
