Answer:

27 of the pets are dogs.

Step-by-step explanation:

Real easy way to do this, treat 45 (the total) as 100. So, do 45/100 then multiply the result of that by 60, and you end up with 27.

45/100=0.45

0.45*60=27

What is the volume of a right circular cone that has a height of 18.8 m and a base with a radius of 19.3 m
12345 [234]

Answer: 7,333.32 m3

Step-by-step explanation:

Hi, to answer this question we have to apply the next formula:

Volume of a cone = 1/3 x π x radius^2 x height

Replacing with the values given:

V = 1/3 π (19.3)^2 (18.8) = 7,333.32 m3

The volume of the right circular cone is 7,333.32 cubic meters.

Feel free to ask for more if needed or if you did not understand something.

Meredith solved a quadratic equation. Her work is shown below.
Damm [24]

Answer:

Step 2

Step-by-step explanation:

Meredith made a fatal mistake or error in step 2;

Any quadratic problem will always have two solutions. Therefore since, we only have one solution here, it is wrong. The mistake was incurred in step 2;

  From the given problem ;

    <u> Wrong                                                  right</u>

    2(x + 4)² = 242

    (x + 4)² = 121     Step 1  

     x+4=11              Step 2                  x + 4  = ± 11

     x  = 7                Step 3                  x + 4  = 11 or x + 4  = -11

                                                           x  = 11- 4     or    x  = -11 - 4

                                                           x  = 7 or -15
