ycow [4]

Answer:

Base = 16 inches

Step-by-step explanation:

A triangular Bandana has an area of 70 square inches

The height of the triangle is 8\frac{3}{4}

Area of a triangle is given by;

\frac{1}{2} × base × height

∴

\frac{1}{2} × base × \frac{35}{4} = 70

base = \frac{70 * 2 * 4}{35} = 16 inches

What is the most accurate representation of the area of a plot measuring 11.7 cm by 15.4 cm?
sergiy2304 [10]
In the given question the length and width of the plot are already given. although there is no direct specification regarding the one that is length or the one that is the width, so it can be taken as your own choice. This will not affect the ultimate answer. 
So
Area of the rectangular plot = Length * Width
                                             = 11.7 * 15.4 square cm
                                             = 180.18 square cm
So the area of the rectangular plot as can be seen from the above deduction is 180.18 square centimeter.

P what equation in slope-intercept form represents the line that passes through the points (3,5) and (-9,2)
ivanzaharov [21]

Answer:

y =\frac{1}{5}x+\frac{22}{5}

Step-by-step explanation:

To write the equation of a line, use the slope formula to first find the slope.

m=\frac{y_2-y_1}{x_2-x_1}=\frac{5-2}{3--9}=\frac{3}{3+12}=\frac{3}{15}=\frac{1}{5}

Substitute m=1/5 and the point (3,5) into point slope formula.

y-y_1 = m(x-x_1)\\y-5=\frac{1}{5}(x-3)\\y-5=\frac{1}{5}x -\frac{3}{5}\\y =\frac{1}{5}x+\frac{22}{5}
