The city designers drawing the road map for new housing development hurricane Ln runs through the coordinates (11, 5) and (-1, 1

AnnyKZ [126]

Answer:

-3

Step-by-step explanation:

Use slope formula to find the slope of the first road:

(y2 - y1) / (x2 - x1)

(1 - 5) / (-1 - 11)

-4 / -12

1 / 3

The slope of a line perpendicular to this line would just be the negative reciprocal of the slope:

-3 / 1 or just -3

What is the area of a trapezoid that has bases of 1feet and 14 inches and a height of 3 inches? A 43.5 in.^2 B 87 in.^2 C 22.9 i

Black_prince [1.1K]

Answer:

Option A. $43.5\ in^{2}$

Step-by-step explanation:

we know that

The area of a trapezoid is equal to

$A=(1/2)(b1+b2)h$

we have

$b1=1\frac{1}{4}\ ft$

$b2=14\ in$

$h=3\ in$

Convert feet to inches first

Remember that

$1\ ft=12\ in$

$1\frac{1}{4}\ ft=\frac{5}{4}\ ft=12*\frac{5}{4}=15\ in$

substitute in the formula

$A=(1/2)(15+14)3=43.5\ in^{2}$
