Answer:130.833333333333
Step-by-step explanation:
25x5=125
125x3.14=392.5
392.5x 1/3=130.83333333333333
The three is recurring
Answer: x + 7y = 12
Explanation:
The question is: "I<span>ndicate in standard form the equation of the line passing through the given points. E(-2, 2), F(5, 1)"
</span>
1) The standard form of the equation of the line passing through two points is:
Ax + By = C
2) You can find the equation of al line given two points in a two stages process:
i) Find the slope:
slope = m = [y₂ - y₁] / [ x₂ - x₁] = [1 - 2] / [5 - (-2) ] = - 1 / 7
ii) set the point slope equation:
y - y₁ = m [x - x₁]
y - 1 = (-1/7) (x - 5) ⇒ 7 ( y - 1) = - (x - 5)
⇒ 7y - 7 = - x + 5 ⇒ x + 7y = 5 + 7
⇒ x + 7y = 12

Answer:
Step-by-step explanation:
f ∝ ghj
Convert the proportion to an equality
f = kghj
Calculate the value of k
18 = k × 4 × 3 × 5
18 = 60k
k = ⅓
Rewrite the equation with the value of k
f = ⅓gkj
Find the new value of f
f =⅓ × 5 × 12 × 3 =
A = L * W
A = 20 * 24
A = 480 sq ft.....so her garden is 480 sq ft.
1 qt of fertilizer covers 300 sq ft....so how many quarts will cover 480 sq ft.
set this up as a proportion
1/300 = x / 480....1 qt to 300 sq ft = x qts to 480 sq ft
cross multiply
(300)(x) = (1)(480)
300x = 480
x = 480/300
x = 1.6.....so Danielle will need 1.6 qts to cover her garden <==
$478 by using the provided formula ...
