Answer:
Amount of B used = 276.6 millimeters
Step-by-step explanation:
A = A millimeters
B = A + 400 millimeters
Hence
Taking an overall balance
(0.16 x A) + (0.2)(A+400) = 476
0.16A + 0.2A + 80 = 476
A = 1100 millimeters
B = 1100 + 400 = 1500 millimeters
Hence using direct proportion
2600 --------------------476
1500 ---------------------X
X = 276.61538
Amount of B used = 276.6 millimeters
Answer:
y=2x+3
Step-by-step explanation:
slope is rise over run. goes up to and over one so your slope is 2/1 or 2.
the c part of the equation of the line is your y-intercept(where the line crosses the y-axis) this is at 3.
so, y=2x+3
Answer:
The total surface area of this box is 62.14 square feet
Step-by-step explanation:
Given:
Length = 3.5 feet
Width = 2.2 feet
Height = 4.1 feet
To Find:
The Surface area of the prism = ?
Solution:
The box is the shape of rectangular prism
Then the surface area of the prism = 2(lh +hw +wl)
Where
l is the length
w is the width
h is the height
Substituting the values
The surface area of the prism =
The surface area of the prism = 2(14.35 + 9.02 + 7.7)
The surface area of the prism = 2(31.07)
The surface area of the prism = 62.14 square feet
Answer:
(4x^2 +9)(4x^2-9) =0
Step-by-step explanation:
16x^4 - 18 = 0
Rewriting
(4x^2)^2 - 9^2 =0
We notice that this is the difference of squares
a^2 - b^2 = (a-b)(a+b)
(4x^2 -9)(4x^2+9) =0
