The answer is B: 6 cm. You can use guess-and-check method, and plug the possible different answers into the equation x(x+6)=72, x stands for the width.

Solve the equation. Then check your solution.<br> 5/9d = 9/10
sdas [7]

Answer:

d=1.62

The equation is TRUE.

Step-by-step explanation:

To solve the given equation:

\frac{5}{9}d=\frac{9}{10}

You need to find the value of the variable "d". You can apply this procedure:

- Multiply both sides of the equation by 9:

(9)(\frac{5}{9}d)=(\frac{9}{10})(9)\\\\5d=\frac{81}{10}\\\\5d=8.1

- Divide both sides of the equation by 5:

\frac{5d}{5}=\frac{8.1}{5}\\\\d=1.62

Check the solution substituting the value of "d" into the equation and evaluating:

\frac{5}{9}(1.62)=\frac{9}{10}\\\\0.9=0.9\ (TRUE)

Can I get help on this please? You will be marked Brainliest and 5 ⭐️ <br> Thank you!!!

Answer:

y = 50x

Step-by-step explanation:

the equation for this is y = 50x because for every 50 units we go up by on the graph we go 1 unit to the right so:

slope-intercept form: y = mx + b   where m is the slope and b is the y-intercept. Our y-intercept is 0 because that is where our line intersects the y-axis and because it is 0 we do not need to put it in the equation.

y = 50x

Find the area of the shape.
myrzilka [38]

Answer:

Area of the given quarter of the circle=78.5units^2

Step-by-step explanation:

The given figure is a quarter or sector of a circle with an angle of 90°

Area of the quarter of a circle:

                                              =    \frac{\pi *r^2}{4}

Area of the given quarter with a radius of 10 unit

                                 =\frac{3.14*10*10}{4}

                                =\frac{3.14*100}{4} \\\\=\frac{314}{4} \\\\=78.5units^2

The area of the given quarter of the circle=78.5units^2
