Answer:

B. A shirt costs $15, and a pair of shoes costs $20.

Step-by-step explanation:

Let s = price of 1 shirt.

Let p = price of 1 pair of shoes.

Adam:

5s + 4p = 155

Friend:

3s + 2p = 85

We have a system of simultaneous equations.

5s + 4p = 155

3s + 2p = 85

Rewrite the first equation. Multiply both sides of the second equation by -2 and write below it. Add the equations.

      5s + 4p = 155

(+)  -6s - 4p = -170

--------------------------

      -s          = -15

s = 15

A shirt costs $15.

Now we replace s with 15 in the first original equation and solve for p.

5s + 4p = 155

5(15) + 4p = 155

75 + 4p = 155

4p = 80

p = 20

A pair of shoes costs $20.

Elena-2011 [213]
Mes angle P = mes arc (ORQ) / 2

mes angle R = mes arc(OPQ) / 2

But mes arc(OPQ+ORQ) = 360° & ===> mes angle (P+R) =arc(OPQ+ORQ) /2

= 180°. Then P+R =180°.

Replace P & R by their respective values: y°+3y°+8°=180°
4y° = 172° ===> y°=43°

B) 4\pit²

C) 4\pi(30)² which will end up being 11310 in²

Step-by-step explanation:

A) If it increases 2 inches every minute, you would take that and put it with the t, aka time.

B) A=\pir² which will translate into A=\pi(2)²

C) You take the half-hour, which is 30 minutes, and translate that into t then place that into your calculator and get an answer of 11,309.73 and then round up to the whole number

Rachel is a stunt driver, and she's escaping from a building that is about to explode!
lilavasa [31]

Answer: 38 meter per second


Step-by-step explanation:

Given: The variable  d models Rachel's distance from her exit (in meters) t seconds after the cameras began recording the stunt.

d=-38t+220

where -38 is the rate of change of function .

Since speed is the rate of change of position with respect to time , thus

Speed =-38 meter per second which shows decrease in distance with respect to time.

At t=0 second, d=220 meters

At t=1 second , d=-38+220 =182 meters

Distance traveled in 1 second = 220-182=38

Now, Rachel's speed=\frac{Distance}{time}

Rachel's speed=\frac{38}{1}=38 meter per second
