What percentage of the shape is purple?

85%

Step-by-step explanation:

There are 4·5=20 boxes total.

4·4+1=16+1=17 of them are purple

17/20

17/20 as a decimal is 0.85

To convert a decimal into a percent multiply it by 100

0.85·100=85%

85%

Step-by-step explanation:

4 * 5 = 20 blocks in total

3 blocks uncovered.

so,  ( 20 - 3 ) / 20  * 100

= 85%

no, because the sides are not congruent

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.
