Answer:

The correct answer is option A , 0.5

$0.5$

Step-by-step explanation:

We know that,

Voltage is the product of current flowing through a conductor in amperes and its resistance

$Voltage = current * resistance\\18 V = 36 Amperes * Resistance\\Resistance = \frac{18 V}{36 Amperes} \\= 0.5 Volt/Ampere\\= 0.5 ohm\\$

What is the value of y?

dimaraw [331]

All angles in a triangle = 180. SO we can make an equation to find y:
79+37+y=180
116+y=180 (combine like terms)
y=64 (subtract the 116)

Jeffrey has an aquarium in the shape of a rectangular prism. He is going to place a layer of sand over the base for his iguana.

nikitadnepr [17]

Answer:

$Length = 6x^2 - 2x + 3$

Step-by-step explanation:

Given

$Area = 42x^3 - 14x^2 + 21x$

$Width = 7x$

Required

Determine the length of the aquarium

The area of a rectangular base is calculated as:

$Area = Length * Width$

Substitute values for Area and Width

$42x^3 - 14x^2 + 21x = Length * 7x$

Make Length the subject

$Length = \frac{42x^3 - 14x^2 + 21x}{7x}$

Factorize the numerator

$Length = \frac{7x(6x^2 - 2x + 3)}{7x}$

$Length = 6x^2 - 2x + 3$

For the linear equation, find the product of 5 and the linear equation, and solve both equations for y. 2x + 7y = 11

tensa zangetsu [6.8K]

Answer:

(a) $10x + 35y = 55$

(b) $y = \frac{11 - 2x}{7}$

Step-by-step explanation:

Given

$2x + 7y = 11$

Solving (a): Multiply equation by 5.

Multiply both sides by 5

$5 * (2x + 7y) = 11*5$

Open bracket

$5 * 2x + 5 * 7y = 11*5$

$10x + 35y = 55$

(b) Solve for y in $10x + 35y = 55$ and $2x + 7y = 11$

$10x + 35y = 55$

Subtract 10x from both sides

$35y = 55 - 10x$

Divide both sides by 35

$\frac{35y}{35} = \frac{55 - 10x}{35}$

$y = \frac{55 - 10x}{35}$

Factorize the numerator:

$y = \frac{5(11 - 2x)}{35}$

Express 35 as 7 * 5

$y = \frac{5(11 - 2x)}{7 * 5}$

$y = \frac{(11 - 2x)}{7}$

$y = \frac{11 - 2x}{7}$

When $2x + 7y = 11$ is solved, the solution will be: $y = \frac{11 - 2x}{7}$
