Answer:

$\mathsf {x = 76}$

Step-by-step explanation:

The given pair of angles lie on a line, hence they are classified as linear angles. They possess the property by which their sum is equal to 180°.

$\textsf {Solving :}$

$\implies \mathsf {x + 17 + 87 = 180}$

$\implies \mathsf {x + 104 = 180}$

$\implies \mathsf {x = 180 - 104}$

$\implies \mathsf {x = 76}$

The average weight of 7 potted plants is 23 pounds. An 8th potted plant is added to the pallet,

cluponka [151]

Answer:

The weight of the 8th plant is 39lb

Step-by-step explanation:

Given:

Average Weight of 7 plants = 23lb

Average Weight of 8 plants = 25lb

Required:

Weight of the 8th plant

To solve this, the total weight of the initial 7 plants need to be calculated;

$Average = \frac{Sum-of-weights}{Number-of-Plants}$

Substitute 23 for Average and 7 for Number of plants

$23 = \frac{Sum-of-weights}{7}$

Multiply both sides by 7

$7 * 23 = \frac{Sum-of-weights}{7} * 7$

$161 = Sum-of-weights$

Hence, the 7 plants weigh 161

Represent the weight of the 8th plant with E

When the 8th plant is added;

The sum of the weight becomes 161 + E

And the number of plants becomes 8

The average is calculated as thus

$Average = \frac{Sum-of-weights}{Number-of-Plants}$

$25 = \frac{161 + E}{8}$

Multiply both sides by 8

$8 * 25 = \frac{161 + E}{8} * 8$

$200 = 161 + E$

Subtract 161 from both sides

$200 -161 = 161 - 161 + E$

$39 = E$

Reorder

$E = 39$

Hence, the weight of the 8th plant is 39lb

The magnitude of the resulting vector, u - v, is approximately 5.83

and its angle of direction is approximately 59.04°.

<h3>How to find the magnitude of the resulting vector?</h3>

We want to subtract vector v from vector u.

We are given;

v = <2, -3> = 2i - 3j

u = <5, 2> = 5i + 2j

u - v = 5i + 2j - (2i - 3j)

= 5i + 2j - 2i + 3j

= 3i + 5j

Resultant vector = √(3² + 5²)

Resultant vector = √34 ≈ 5.83

Angle of direction of resultant vector is;

tan θ = (5/3)

θ = tan⁻¹(5/3)

θ = 59.04°
