Mathematics
1 answer:
Ainat [17]3 years ago
3 0

Answer:

7\frac{11}{35}

Step-by-step explanation:

2\frac{5}{7}+4\frac{3}{5}

add the whole numbers

2+4=6

combine the fractions

\frac{5}{7}+\frac{3}{5}

LCM is 35 because 7 * 5 =35

\frac{5}{7}=\frac{5\cdot \:5}{7\cdot \:5}=\frac{25}{35}

\frac{3}{5}=\frac{3\cdot \:7}{5\cdot \:7}=\frac{21}{35}

\frac{25}{35}+\frac{21}{35}=\frac{25+21}{35}

=\frac{46}{35}

change the improper fraction into mixed number

6+1\frac{11}{35}

=7\frac{11}{35}

Find the missing dimension of each prism: volume= 56 1/4 ft | width= 3 3/4 ft | length= 7 1/2 ft
Juliette [100K]

56.25=3.75*7.5*h

h=(56.25)/(3.75*7.5)=2

So that the missing dimension (height) is 2 ft
