10 POINTS!! Made myself broke with my last two questions!

Svet_ta [14]

Answer:

Step-by-step explanation:

The radius r is the distance from the centre to a point on the circle.

Calculate r using the distance formula

r = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (- 5, - 12)

r = $\sqrt{(-5-0)^2+(-12-0)^2}$

= $\sqrt{(-5)^2+(-12)^2}$

= $\sqrt{25+144}$

= $\sqrt{169}$

= 13 → D

The Pit BBQ food truck sells two combo packs of ribs and brisket. Combo A contains 10 oz of brisket and 16 oz of ribs and sells

GenaCL600 [577]

The maximum revenue is $700 which is at 16 combo A and 12 combo B.

<h3>Inequality</h3>

An inequality is an expression that shows the non equal comparison of two or more numbers and variables.

Let x represent the number of combo A and y represent the number of combo B, hence:

10x + 20y ≤ 400 (1)

Also:

x + y ≤ 28 (2)

The solution is at (16,12). Hence:

Revenue = 21.25 * 16 + 30 * 12 = $700

The maximum revenue is $700 which is at 16 combo A and 12 combo B.

Two jet planes simultaneously started travelling in opposite directions from the same airport. Four hours later they were 3800 m

alexira [117]

Answer:

Step-by-step explanation:

let the speed of one plane=x

speed of other plane=x+80

time=4 hrs

then 4x+4(x+80)=3800

4x+4x+320=3800

8x=3800-320

or 8x=3480

x=435

speed of one plane=435 m/h

speed of other plane=435+80=515 m/h

Let he walks x hrs

then he take a taxi for 2-x hrs

4x+(2-x)50=31

4x+100-50x=31

-46x=-69

$x=\frac{-69}{-46}=\frac{3}{2}$

so he walks 3/2 hrs=1.5 hrs

travels by taxi=2-1.5=0.5 hrs

distance traveled by taxi=0.5×50=25 miles
