the ratio of length, breadth and height of a room is 4:3:1. If 12m^3 air is contained in a room, find the length , breadth and h

Sladkaya [172]

Answer:

length = 4 m

breadth = 3 m

height = 1 m

Step-by-step explanation:

well since it's a ratio we can say that

length = 4x

breadth = 3x

height = 1x

so the volume will be

$V=4x\cdot 3x\cdot x\\\\V=12x^3$

and we know that

$V=12m^3$

so we have

$12m^3=12x^3\\\\1m^3=x^3\\\\x=1m$

so we have

length = 4 m

breadth = 3 m

height = 1 m

Examine the diagram of circle V, where two chords, JK and LM, are equidistant from the center. If JK=4x+37, and LM=5(x+5), what

77julia77 [94]

Answer:

x=12

Step-by-step explanation:

we know that

If the two chords are equidistant from the center of the circle, then the chords must be congruent.

JK=LM

substitute the given values

$4x+37=5(x+5)$

solve for x

$5x-4x=37-25\\x=12$

What is the slope of the line in the graph?

Allisa [31]

Answer:

slope = 1

Step-by-step explanation:

Calculate the slope m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (- 1, 0) and (x₂, y₂ ) = (0, 1) ← 2 points on the line

m = $\frac{1-0}{0+1}$ = 1
