Answer:

<h3> $\boxed{ \bold{ \blue{ Joule}}}$ </h3>

Step-by-step explanation:

The SI unit of work is Joule.

Further more explanation:

▪️ $\blue{ \mathsf{ {What \: is \: Work \: ?}}}$

⇒Work done by a force acting on a body is defined as the product of force and displacement of the body in the direction of the force.

▪️ $\blue{ \bold{ \sf{What \: is \: SI \: unit \: ?}}}$

⇒The system of units which is agreed by the international convention of scientists held in France in 1960 is called SI unit.

▪️ $\blue{ \bold{ \sf{What \: do \: you \: mean \: by \: \: one \: joule \: work \: \: ?}}}$

⇒One joule is the amount of work done when one Newton force displaces a body through one metre in its own direction.

Find the area of a triangle with a =33, b =51, and c =42.

PolarNik [594]

Answer:

d. 690.1 units²

Step-by-step explanation:

1. You can use the Heron's formula to calculate the area of the triangle, which is:

$K=\sqrt{s(s-a)(s-b)(s-c)}$

Where:

$s=\frac{a+b+c}{2}$

2. Calculate $s$ :

$s=\frac{33+51+42}{2}\\s=63$

3. Substitute values into the formula shown above and calculate the area, as following:

$K=\sqrt{63(63-33)(63-51)(63-42)}\\K=690.1units^{2}$

4. Therefore, the area is 690.1 units².

Which dimensions can create only one unique triangle?

s2008m [1.1K]

Answer:

<h2>The dimensions must all add up to 180°.</h2>

Step-by-step explanation:

For example;

Your triangles' angles are: 56, 77, and 47.

56 + 77 + 47 = 180

*You did not give me any values to solve for, but just since you didn't- I'v provided an example to assist you in doing it yourself. If you want me to solve your full equation please add the angles or 3 dimensions of the triangle.

You ask a neighbor to water a sickly plant while you are on vacation. Without water the plant will die with probability 0.75. Wi

Dafna1 [17]

Answer:

0.2915

Step-by-step explanation:

Let W represent water and D represent Dying probability

W = water

D = die

->If with water, it will die with probability 0.4

P(W & D) = 0.82 x 0.4 = 0.328

->Without water the plant will die with probability 0.75

P(W ' & D) = 0.18 x 0.75 = 0.135

Taking sum of the above values with water and without water.

P(D) = P(W & D) + P(W ' & D) = 0.4643

P(W ' | D) = P(W ' & D) / P(D)

= 0.135 /0.463

= 0.2915 ≈ 29.15%

Thus, the probability the neighbor forgot to water is 0.2915

Mika bought 9 rolls of film to take 180 pictures on a field trip. Some rolls had 36 exposures and the rest had 12 exposures. How

Juli2301 [7.4K]

The number of each type Mika bought =x = 6.8 rolls; y= 2.2 rolls.

<h3>Calculation using ratio</h3>

The number of rolls of film Mika bought = 9 rolls

The number of rolls that had 36 exposures = x

The number of rolls that had 12 exposures = y

The total number of exposures = 36 + 12 = 48

To find the exposure by one roll = 48/9 = 5.3

If one roll = 5.3 exposure

x roll = 36 exposure

Make x roll the subject of formula,

x roll = 36/5.3 = 6.8 rolls

If one roll = 5.3 exposure

y roll = 12 exposure

Make y roll the subject of formula,

y = 12/5.3 = 2.2 rolls

Therefore, the number of each type Mika bought = x = 6.8 rolls; y= 2.2 rolls.
