Afish tank has the shape of a rectangular prism. it has a length of 2 1/4 meters, width of 7/8 meters, and a height of 1 1/2 meters. what is the volume of the fish tank? 1 31/32 m³ 2 61/64 m³ 4 5/8 m³ 13 5/16 m³

2 61/64 m³

Step-by-step explanation:

The volume is the product of the linear dimensions. Likely you will need a calculator for this. You may as well have it work the whole problem. (see attachment)

___

If you want to work it by hand, the recommended way is to convert the mixed numbers to improper fractions.

... V = LWH

... V = (2 1/4 m)(7/8 m)(1 1/2 m) = (9/4)(7/8)(3/2) m³

... = (9·7·3)/(4·8·2) m³ = 189/64 m³ = 2 61/64 m³

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
