How many (5in. by 5in. by 5in) cubes will occupy a classroom 9ft by 8ft by 7ft in dimension?

Mathematics
1 answer:
finlep [7]2 years ago
8 0

Answer:

Step-by-step explanation:

first convert feet to inches because the measure of cubes is in inches

( 12 inches=1 foot)

9 ft = 12*9=108 inches

8 ft=12*8=96 inches

7 ft= 12*7=84

the volume of the one cube= 5*5*5=125

volume of the classroom: 108*96*84=870912

divide : 870912/125=6967 cubes

Write 5/10 in three equivalent forms
krek1111 [17]

equivalent fractions are fractions which have the same value.

equivalent fractions all have the same simplified form

we can write equivalent fractions by multiplying both numerator and denominator by the same number. We can also write equivalent fractions by dividing both numerator and denominator by the same number

so 5/10

we can get the equivalent fractions by multiplying by a common number

when we multiply by 2

\frac{5}{10}* 2= \frac{5*2}{10*2} = \frac{10}{20}

when we multiply by 3

\frac{5}{10}* 3 = \frac{5*3}{10*3} = \frac{15}{30}

when we multiply by 4

\frac{5}{10} *4 = \frac{5*4}{10*4}  = \frac{20}{40}

the three equivalent fractions are

10/20 , 15/30, 20/40

Give two examples of line segments that will make a triangle ?
77julia77 [94]

Answer:

If the length of any one side is greater than the sum of the length of the other two, the line segments cannot be used to create a triangle. It is possible to create a triangle using 3 line segments if the sum of the lengths of any two line segments is greater than the length of the third.

The penny size of a nail indicates the length of the nail. The penny size d is given by the literal equation d=4n−2, where n is
sleet_krkn [62]
D=4n-2, d+2=4n-2+2, d+2=4n
(d+2)/4=(4n)/4, 1/4d+1/2=n
n=1/4n+1/2

size 3=
n=1/4*3/1=3/4, 3/4+1/2=5/4=1 1/4
size 3=1 1/4

size 6=
n=1/4*6/1=6/4, 6/4+1/2=8/4=2
size 6=2

size 10=
n=1/4*10/1=10/4, 10/4+1/2=12/4=3
size 10=3
