Layla used 0.482 gram of salt in her experiment. Maurice use 0.51 gram of salt. Who used the greater amount of salt?

0.51>0.482
The number (5) in the tenth column (the number on the right of the decimal)
is greater than the other number in the tenth column (4)

0.51 is greater than 0.482

Hope this helps! A thanks/brainiest answer would be appreciated :)

Answer: Maurice used greater amount of salt.

Step-by-step explanation:

Since we have given that

Quantity of salt in her experiment that Layla used = 0.482 grams

Quantity of salt in her experiment that Maurice used = 0.51 grams

As we know that

$0.51=\dfrac{51}{100}\\\\and\\\\0.482=\dfrac{482}{1000}$

So, for comparison we will write 0.51 as $\dfrac{510}{1000}$

Now, we can compare easily:

$\dfrac{510}{1000}>\dfrac{482}{1000}\\\\=0.51>0.482$

Hence, Maurice used greater amount of salt.

Answer:

Vertical angles = 81 degrees

Angle (4y-1) = 99 degrees

Linear pair = 81 + 99 = 180 degrees

Step-by-step explanation:

2x + 5 = 3x - 33 (vertical angles)

33+5 = 3x - 2x

38 = x

3(38) - 33 = 81 degrees

4y - 1 + 81 = 180 (linear pair angles)

4y = 180 - 80

y = 100/4

y = 25

4(25) -1 = 99 degrees

Determine the equation of the circle with center (0,6) containing the point (74,2)

Lubov Fominskaja [6]

The circle with center (0,6) containing the point (74,2) has an equation of x² + (y - 6)² = 74.1²

<h3>How to calculate the equation of a circle</h3>

The equation of a circle is:

(x - h)² + (y - k)² = r²

Where (h, k) is the center and r is the radius.

The circle with center (0,6) containing the point (74,2). Hence:

$Radius=\sqrt{(2-6)^2+(74 -0)^2}=74.1\ unit$

The equation is:

x² + (y - 6)² = 74.1²

The demand for mineral water is P=10 – (2/3)Q and supply function for mineral water is P=1+(1/3)Q

oksano4ka [1.4K]

Answer:

Equilibrium

We have:

+) Demand function: $P = 10 - \frac{2}{3} Q_{demand}$

=> $Q_{demand} = (10 - P)/\frac{2}{3} = (10-P).\frac{3}{2} = 15 - \frac{3}{2} P$

+) Supply function: $P = 1 + \frac{1}{3} Q_{supply}$

=> $Q_{supply} = (P-1)/\frac{1}{3} = (P-1).3 = 3P - 3$

The market of mineral water is at equilibrium when the quantity of demand is equal to the quantity of supply at a price level.

We have: Qdemand = Qsupply

⇔ $15 - \frac{3}{2} P = 3P - 3$

⇔ $15 + 3 = 3P + \frac{3}{2} P$

⇔ $18 = \frac{9}{2} P$

⇔ $P = 18/ \frac{9}{2} = 18 .\frac{2}{9} = 4$

When P = 4

⇒ $\left \{ {{Q_{demand} = 15 - \frac{3}{2}P = 15 -\frac{3}{2}.4 = 9 } \atop {Q_{supply} = 3P - 3 = 3.4 - 3 = 9}} \right.$

Price elasticity:

At P = 4, Qd = Qs = 9

+) Demand function:

$Q_{demand} = 15 - \frac{3}{2} P$ => $dQ_{D} = -\frac{3}{2}$

Price elasticity of demand is:

$E_{D} = dQ_{D}.\frac{P}{Q_{D} } = -\frac{3}{2} . \frac{4}{9} = -\frac{2}{3}$

+) Supply function:

$Q_{supply} = 3P - 3$ => $dQ_{S} = 3$

Price elasticity of supply is:

$E_{S} = dQ_{S}.\frac{P}{Q_{S} } = 3. \frac{4}{9} = \frac{4}{3}$

So equilibrium price is 4, equilibrium quantity is 9.

Price elasticity of demand is -2/3; Price elasticity of supply is 4/3

Initially, the market is at equilibrium at point A: P=4; Qd = Qs = 9

When a unit of tax is imposed on the suppliers, it will shift the supply curve to the left a distance = t = 3 TL. (We can see in the attached image).

The new supply curve intersects the demand curve at point B.

The market moves to the new equilibrium at point B: Q = Q2; Price producers get after tax = Price consumers pay - Tax

When a unit of tax is imposed, it will result in the difference between the price consumers pay and price producers receive at the equilibrium , which is equal to the tax.

We have:

$P_{D} = 10 - \frac{2}{3} Q_{demand}$

$P_{S} = 1 + \frac{1}{3} Q_{supply}$

And at equilibrium, Q demand = Q supply, so we have the equation:

$P_{S} - P_{D} = t$

⇔ $10 - \frac{2}{3} Q - (1+ \frac{1}{3} Q) = 3$

⇔ 9 - Q = 3

⇔ Q = 9 - 3 = 6

⇒ $P_{D} = 10 - \frac{2}{3} Q_{demand} = 10 - \frac{2}{3} .6 = 6$

$P_{S} = 1 + \frac{1}{3} Q_{supply} = 1 + \frac{1}{3} .6 = 3$

New equilibrium: Quantity = 6

+) Price consumers pay = 6

+) Price suppliers receive = 3

When the tax is imposed on the producers, it will create the burden on both producers and consumers.

As we can see it the attached image, the blue part represents the total tax that the government would receive, it can be calculated as:

Tax revenue = Tax × Equilibrium Quantity = 3 x 6 = 18

The burden of tax on consumers is illustrated by the area of rectangle a

=> Burden tax on consumers = (4 - 3) x 6 = 6

=> Burden tax on producers = 18 - 6 = 12

When the government imposes the tax, if the price elasticity of demand is less than price elasticity of supply, the consumers will have heavier burden of tax.

Vice versa, if the price elasticity of demand is greater than price elasticity of supply, the consumers will have less burden of tax.

=> The more inelastic, the heavier burden of tax and vice - versa
