Which describes an isometric transformation? dilation/ rotation/ side length change/ angle change
Westkost [7]

Answer:

  rotation

Step-by-step explanation:

"Isometric" means all measures stay the same.

  • dilation changes all lengths
  • <em>rotation changes no measures -- an isometric transformation</em>
  • side length change obviously changes the length of a side
  • angle change obviously changes the measure of an angle

An auto mechanic converts a metric part to 0.492 in. The part comes only in fractional sizes given to the nearest 64th of an inc
tatuchka [14]

Answer:

the closest part the mechanic can chose is 0.5 inch

Step-by-step explanation:

fractional sizes given to the nearest 64th of an inch = 1/64 = 0.0156

the closest size to 0.492in = 0.492 + 0.0156 = 0.5076 inches

approximately, the closest part the mechanic can chose is 0.5 inch

RSTUV - EABCD. Find AE.
larisa86 [58]

9514 1404 393

Answer:

  AE = 3

Step-by-step explanation:

First of all, we need to find corresponding sides that are defined in both figures. The table below shows the given values.

From the table, we can write the proportion ...

  EA/RS = BC/TU . . . corresponding sides are proportional

  EA/6 = 4/8 . . . . . . . substitute given lengths

  EA = 6(4/8) = 3

The length of AE is 3 units.

3 Ramón makes nectar for a hummingbird feeder by mixing 8 cups of water with 2 cups of sugar. Tiffany makes nectar by mixing 9 c
Butoxors [25]

Answer:

Tiffany's nectar is more sugary

Step-by-step explanation:

Given

Ramon:

Water = 8\ cups

Sugar = 2\ cups

Tiffany

Water = 9\ cups

Sugar = 3\ cups

Required

The nectar with more sugar

To do this, we simply calculate the fraction of sugar in both nectar.

This is calculated as:

Fraction = \frac{Sugar}{Sugar + Water}

For Ramon:

Fraction = \frac{2}{8 + 2}

Fraction = \frac{2}{10} = 0.20

For Tiffany

Fraction = \frac{3}{3 + 9}

Fraction = \frac{3}{12} = 0.25

From the calculations above:

0.25 > 0.20

Hence: Tiffany's nectar is more sugary
