Answer:

since ABC and ADE are similar,they have equal areas.

(AC)^2/(AE)^2=area ABC/ADE

areaABC=ACE=1

so substitute it in the afformentioned equation

A trapezoid is broken into 2 triangles and 1 rectangle. The triangles both have a base of 2 meters and a height of 5 meters. The

Lemur [1.5K]

Answer:

Part 1) The trapezoid has an area of $20\ m^2$

Part 2) The kite has an area of $21\ m^2$

Part 3) The area of the trapezoid is less than the area of the kite

Step-by-step explanation:

Part 1

Find the area of trapezoid

we know that

The area of trapezoid is equal to the area of two congruent triangles plus the area of a rectangle

$A=2[\frac{1}{2} (2)(5)]+(2)(5)$

$A=10+10=20\ m^2$

Part 2

Find the area of the kite

we know that

The area of the kite is equal to the area of two congruent triangles

$A=2[\frac{1}{2} (7)(3)]=21\ m^2$

Part 3

Compare the areas

The trapezoid has an area of $20\ m^2$

The kite has an area of $21\ m^2$

$20\ m^2< 21\ m^2$

therefore

The area of the trapezoid is less than the area of the kite

Find an input that yield an output of -1 rule y=-2x+33

djyliett [7]

Input (x-value)

Output (y-value)

You need to find the x-value that produces a y-value of -1. Since you know:

y = -1 Use the rule, and substitute/plug this into the equation

y = -2x + 33 Plug in -1 for "y" in the equation since y = -1

-1 = -2x + 33 Subtract 33 on both sides

-1 - 33 = -2x + 33 - 33

-34 = -2x Divide -2 on both sides to get "x" by itself

$\frac{-34}{-2}=\frac{-2x}{-2}$

17 = x

An input of 17 yields an output of -1

HELP!!

taurus [48]

Lets convert

1mile=5280ft
1h=3600s

$\\ \rm\longmapsto 1mph$

$\\ \rm\longmapsto \dfrac{5280}{3600}ft/s$

$\\ \rm\longmapsto 1.46ft/s$

If rounded

$\\ \rm\longmapsto 1.5ft/s$
