Answer:

  • Area = -20x + 100
  • Perimeter = -4x + 40

Step-by-step explanation:

<u>Given rectangle with</u>

  • Length l = - 2x + 10
  • Width w = 10

<u>To find</u>

  • Area
  • Perimeter

<u>Solution</u>

  • A = lw
  • A = (-2x + 10)*10 = -20x + 100
  • P = 2(l +w)
  • P = 2( -2x + 10 + 10) = 2( -2x + 20) = -4x + 40

Thank you for the help!
horrorfan [7]

Answer:

see explanation

Step-by-step explanation:

cosM = \frac{adjacent}{hypotenuse} = \frac{MN}{LM} = \frac{8}{17}

sinM = \frac{opposite}{hypotenuse} = \frac{LN}{LM} = \frac{15}{17}

tanM = \frac{opposite}{adjacent} = \frac{LN}{MN} = \frac{15}{8}

The volume of a gas is 10.0 liters and its pressure is 1.5 atm. If the pressure is decreased to 0.75 atm,
JulsSmile [24]

Answer:

The new volume is 20litres

Step-by-step explanation:

This problem bothers on the expansion of gases

According to Boyle's law

The volume of a given mass of gas at constant temperature is inversely proportional to the pressure

P∝1/v

Pv= constant

Given data

P1= 1.5atm

v1 = 10 litter

P2=0.75atm

v2=?

Applying P1v1= P2v2

v2= P1v1/P2

v2= 1.5*10/0.75

v2= 15/0.75

v2= 20litres

You can find the rise by _ the Y-coordinate of the left point from the y-coordinate of the right point
bixtya [17]

Answer:

Subtracting

Step-by-step explanation:

We know that the slope of a line is given by the rise over run. where rise is vertical difference between two points and run is the horizontal distance between the points.

\text{if }(x_1,y_1) \text{ and }(x_2,y_2)\text{ are two points on a line, then the}\\\text{slope of the line is given by}\\\\\text{Slope, }m=\frac{y_2-y_1}{x_2-x_1}\\\\\text{since slope}=\frac{\text{Rise}}{\text{Run}}, \text{ so Rise}=y_2-y_1\\\\\text{so we can find the rise by subtracting the Y-coordinate of the left point }\\\text{from the y-coordinate of the right point}.

Alexa knock down 70 bowling pins in 10 frames. in each frame, alexa nocked down the same number of pins. how many pins did Alexa
hichkok12 [17]
The answer would be 7 because you would divide 70 by 10 to find out how many were per frame.
