I know the converse but I need to know which ones are true
Ray Of Light [21]

The converse of the statement would be

"If x ≤ 7, then x² ≤ 49"

but this is false. Take x = -8; while it's true that -8 ≤ 7, the second inequality is not, since (-8)² = 64 is not smaller than 49.

A pyramid is 24 ft tall. A scaled model has a height of 2ft and is 1 foot wide at the base. Identify the scale factor that was u
il63 [147K]

Answer:

1/12

Step-by-step explanation:

Given the following :

Actual height of pyramid = 24 ft

Dimension of scaled model :

Height = 2ft ; width = 1ft

The scale factor is a number used to reproduce a reduced dimension of a model by multiplying the actual dimeznsion or size of the model or object.

Since the height is of the scaled model is less than the actual height of the pyramid ; then it could be said that the scale factor is a fraction, because reduction has occurred.

(Height of scaled model / height of actual pyramid)

(2ft / 24ft) = 1/12
