The triangles are similar, they aren't congruent (identical) though as we don't know if they share a common side
Write the decimal number as a fraction
(over 1)
19.79 = 19.79 / 1
Multiplying by 1 to eliminate 2 decimal places
we multiply top and bottom by 2 10's
Numerator = 19.79 × 10 × 10 = 1979
Denominator = 1 × 10 × 10 = 100
Numerator / Denominator = 1979 / 100
Simplifying our fraction
= 1979/100
= 1979/100
= 19 79/100
Answer:
The answer to this question is B
Step-by-step explanation: By simplifying both equations to a x = ? both equations lead up to x = -7. Inversely, you can multiply both sides of the first equation by -3 and get the same equation as the second equation.
Fewer numbers of larger units are required to describe the same volume.
a) If the unit of measure changes from a smaller unit to a larger one, the number of units gets smaller
b) The volume doesn't change.
_____
This should be intuitively obvious to anyone with the experience of puting things into containers of any kind. Fewer large containers are required to hold the same amount of stuff that occupies many smaller containers.
_____
<u>Example</u>
54 ft³ = 2 yd³ . . . . the number of units used to describe the volume changes from 54 to 2. The volume is still 93,312 cubic inches. (Note also that both 54 and 2 are smaller than 93,312.)
