Answer:
x=4
x=-5
Step-by-step explanation:
in order for this to be equal to 0, 1 or both of the factors has to be 0, because anything multiplied by 0 is 0.
123 * 29382 * 8139* 0 = 0
x-4 = 0
x = 4
x+5 = 0
x=-5
Answer:
Area of the rectangular park = 2/3 square mile
Let us assume the width of the rectangular park = x
Then
The length of the rectangular park = 2 2/3 * x mile
= 8x/3 mile
Then
Area of the rectangular park = Length * Width
2/3 = (8x/3) * x
2/3 = 8x^2/3
(2 * 3)/3 = 8x^2
2 = 8x^2
x^2 = 2/8
x^2 = 1/4
x^2 = (1/2)^2
x = 1/2
So the width of the park is 1/2 feet.

Answer:
b = 4.6 ft
h = 2.3 ft
Step-by-step explanation:
The volume of the tank is given by:

Where 'b' is the length of the each side of the square base, and 'h' is the height of the tank.
The surface area can be written as:

The value of b for which the derivate of the expression above is zero is the value that yields the minimum surface area:

The value of h is then:

Rounded to the nearest tenth, the dimensions are b = 4.6 ft and h = 2.3 ft.
Answer:
Step-by-step explanation:
1. (-4, -2) (4, 0)
(0 + 2)/(4 + 4)= 2/8= 1/4
2. (-1, 2) (1, -3) = (-3 - 2)/(1 + 1) = -5/2
3. (-2, 3) (0, 0) = (0 - 3)/(0 + 2) = -3/2
4. (1, 1) (3,2) = (2 - 1)/(3 - 1)= 1/2
Answer:
From the calculation it is clear that ratio of paint use by Gina is not same as that of teacher .
Step-by-step explanation:
Given as :
The quantity of yellow paint mix by teacher = 9 pints
The quantity of blue paint mix by teacher = 6 pints
The quantity of yellow paint mix by Gina = 4 pints
The quantity of blue paint mix by Gina = 3 pints
Let The ratio of yellow to blue paint by teacher = x : y
i.e x : y = 9 : 6
or, x : y = 3 : 2
So, The ratio of yellow to blue paint by teacher = 3 : 2
<u>Again</u>
The ratio of yellow to blue paint by Gina = a : b
i.e a : b = 4 : 3
or, a : b = 4 : 3
The ratio of yellow to blue paint by Gina = 4 : 3
Hence, from the calculation it is clear that ratio of paint use by Gina is not same as that of teacher . Answer
