artcher [175]2 years ago
4 0

The simplified expression for the following expression are:

  • 7a + 3a - 2a + 5a = 13a
  • 0.7 - 0.3g - 0.02g + 5 = 5.7 - 0.32g
  • 5g² + 3g - 4g + 5g² = 10g² - g

<h3>Simplification</h3>

7a + 3a - 2a + 5a

= 15a - 2a

= 13a

0.7 - 0.3g - 0.02g + 5

= 5.7 - 0.32g

5g² + 3g - 4g + 5g²

= 10g² - g

Finger [1]

Answer:

Cost of a single Mucho beef burrito: \$5.5

Cost of a double Mucho beef burrito: \$6.5

Step-by-step explanation:

<h3> The exercise is: "The Little Mexican restaurant sells only two kinds of beef burritos: Mucho beef and Mucho Mucho beef. Last week in the restaurant sold 16 orders of the single Mucho variety and 22 orders of the double Mucho. If the restaurant sold $231 Worth of beef burritos last week and the single neutral kind cost $1 Less than the double Mucho, how much did each type of burrito cost?"</h3>

Let be "x" the the cost in dollars of a single Mucho beef burrito and "y" the cost in dollars of a double Mucho burrito.

Set a system of equations:

\left \{ {{16x+22y=231} \atop {x=y-1}} \right.

To solve this system you can apply the Substitution Method:

1. Substitute the second equation into the first equation and solve for "y":

16(y-1)+22y=231\\\\16y-16+22y=231\\\\38y=231+16\\\\y=\frac{247}{38}\\\\y=6.5

2. Substitute the value of "y" into the second equation and evaluate in order to find the value of "x":

x=6.5-1\\\\x=5.5

Lauren has an above-ground pool. to keep the pool's skimmer working well, the water level must be 4 inches from the top of the p
Ostrovityanka [42]

1885.5 m^3 of water will fill the container.

To find how many cubic feet of water will it contain:

Given -

  • Lauren has an above-ground swimming pool.
  • The water level in the pool must be 4 inches above the pool's surface in order for the skimmer to function properly. 
  • π = 3.14

The pool comprises a 12-foot-radius cylinder with a height of 4.5 feet.

  • Height of pool = 4.5 ft
  • Radius of pool = 12 ft
  • The height of the water is 4 inches below the pool top
  • 12 inches make 1 ft
  • 4 inches = 4/12 ft = 0.33 ft
  • Therefore, height of water = 4.5 - 0.33 = 4.17 ft

The volume of the water in this section of the cylinder will be equal to the volume of the cylinder formed.

  • The volume of the cylinder formed by the water = volume of water = \pi r^{2} h
  • volume = 3.14 x 12^{2} x 4.17 = 1885.5 m^3 of water

Therefore, 1885.5 m^3 of water will fill the container.

The quantity demanded x for a product is inversely proportional to the cube of the price p for
Harrizon [31]
X = k/p^3
125 = k/10^3 = k/1000
1000 x 125 = k
k = 125000

x = 125000/p^3

The profit is given by G = px - (125 + 2x) = p(125000/p^3) - 125 - 2(125000/p^3) = 125000/p^2 - 250000/p^3 - 125
For maximum profit:
dG/dp = 0
dG/dp = -250000/p^3 + 750000/p^4 = 0
750000 - 250000p = 0
p = 750000/250000 = 3

Therefore the price that will yeaild maximum profit is $3.
