The area of trapezoid is calculated as -

Area of trapezoid = \frac{a + b}{2} X height

Here, a = base 1

b = base 2

Height is the height of trapezoid.

It is given that,

Area of trapezoid = 166.75 in

Base 1, a = 21 in

Base 2, b = 8 in

Area of trapezoid = \frac{a + b}{2} X height

166.75 in = \frac{21 in + 8 in}{2} X height

Height = [tex] \frac{ 166.75 in}{14.5}

Height = 11.5 in

Thus, height of trapezoid = 11.5 In

The usual equation for a trapezoid is base1+base2/2 * height. For this, 21+8/2 equals to 166.75. Use division, and your height is 11.5

3 drinks and 2 hot dog costs 7.70 and 2 drinks and one hot dog is 4.55 system of equation on drink and one hot dog to the neares
Pepsi [2]

Answer:

Drink = 1.4

Hot dog = 1.75

x + y = 3.15

Step-by-step explanation:

Let drink = x ; hot dog = y

3x + 2y = 7.70 - - (1)

2x + y = 4.55 - - - (2)

From (2)

y = 4.55 - 2x - - - (3)

Put y = 4.55 - 2x in (1)

3x + 2(4.55 - 2x) = 7.70

3x + 9.1 - 4x = 7.70

-x = 7.7 - 9.1

-x = - 1.4

x = 1.4

Put x = 1.4 in (3)

y = 4.55 - 2(1.4)

y = 4.55 - 2.8

y = 1.75

Drink = 1.4

Hot dog = 1.75

x + y = 3.15

Is the equation -x=1-y and 2+y=x+1 coincident, intersecting, or parallel
yarga [219]
\bf x=1-y\implies x+y=1\implies y=-x+1\\\\&#10;-------------------------------\\\\&#10;2+y=x+1\implies y=x+1-2\implies y=x-1

notice the equations in slope-intercept form, the first one has a slope of -1, the second one has a slope of 1.

if the slopes are equal, and the constant is different, they lines are parallel.

if the slopes are equal, and the constant is the same the equations are exactly the same thing, and the lines are coincident, on slapped on top of the other.

if the slopes differ, like here, then they have a solution, where they intersect.
