Answer: 35 dogs

Step-by-step explanation:

Ratio of dogs to cats in first week of January

= 49 : 28

Ratio of dogs to cats in last week of January

= ? : 20

Let the unknown number of dogs for last week be Z

Thus, 49/28 = Z/20

To get the value of Z, cross multiply

49 x 20 = 28 x Z

980 = 28Z

Divide both sides by 28

980Z/28 = 28/28

Z = 35

Thus, there were 35 dogs in the animal shelter during the last week

A cylindrical metal pipe has external diameter of 6cm and internal diameter of 4cm. Calculate the volume of metal in a pipe of l

ArbitrLikvidat [17]

Answer:

volume is 1570 cm³

mass is 12560 g

Step-by-step explanation:

1m = 100 cm

the volume is :

1/4 x $\pi$ x 6² x 100 - 1/4 x $\pi$ x 4² x 100

= 900 $\pi$ - 400 $\pi$ { v = 1/4 $\pi$ d²h }

= 500 $\pi$

= 500 x 3.14

= 1570 cm³

the mass of the pipe is:

1570 x 8 = 12560 grams
