According to the solving the displacement  of the block is:

= 40m

<h3>What does force-displacement mean?</h3>

A shift inside of an object's position is referred to as "displacement." It has a magnitude and a direction, making it a vector quantity. An arrow pointing from of the starting point to the finishing point serves as its symbol. For instance, an object's position changes if it moves from position A to position B.

<h3>Why is there a shift in the workforce?</h3>

The scalar product of displacement and force is equivalent to work. The cosine of the angle between two vectors is added to their lengths to form the scalar product of the two vectors. Work is defined as the product of force, displacement, and the sine of the angle formed by the force's and displacement's directions.

<h3>According to the given data:</h3>

The formula for work is W=F × d.

Work done  = 80J

Force = 20N

Displacement = ?

So,

W=F × d.

80 = 20 x d

d = 80/20

d = 40 m

According to the solving the displacement  of the block is:

= 40m

PtichkaEL [24]

Answer:

\large\boxed{h\leq-\dfrac{19}{6}\to h\in\left(-\infty,\ -\dfrac{19}{6}\right]}

Step-by-step explanation:

\text{First convert the mixed numbers to the improper fractions:}\\\\10\dfrac{2}{3}=\dfrac{10\cdot3+2}{3}=\dfrac{32}{3}\\\\4\dfrac{1}{3}=\dfrac{4\cdot3+1}{3}=\dfrac{13}{3}\\\\\text{Solve the inequality}\\\\10\dfrac{2}{3}+2h\leq4\dfrac{1}{3}\\\\\dfrac{32}{3}+2h\leq\dfrac{13}{3}\qquad\text{multiply both sides by 3}\\\\3\!\!\!\!\diagup^1\cdot\dfrac{32}{3\!\!\!\!\diagup_1}+3\cdot2h\leq3\!\!\!\!\diagup^1\cdot\dfrac{13}{3\!\!\!\!\diagup_1}\\\\32+6h\leq13\qquad\text{subtract 32 from both sides}\\\\6h\leq-19\qquad\text{divide both sides by 6}\\\\h\leq-\dfrac{19}{6}

densk [106]

Answer: 24

Step-by-step explanation:

From the question, we are informed that Micah is buying items for a party and that there are 6 cups in a package and 8 plates in a package.

We are further told that he wants to have the same amount of each item. The least number of packages of cups he needs to buy would be calculated by finding the least common multiple of 6 and 8.

Multiples of 6 = 6, 12 18, 24, 30

Multiples of 8 = 8, 16, 24, 32, 40

The answer is 24 cups

prohojiy [21]
For the first florist you would do $12.50 divided by 4 as there are 2 flower bouquets and 2 vases = $3.125, which represents both b and v 

As for the second florist you would do $29.00 divided by 10 as there are 8 flower bouquets and 2 vases. This results to $2.6, this represents the cost of one b and one v.
