Tickets sold at a school football game cost $1.00 each if purchased before the day of the game. They cost 1.50 each if bought at
Nitella [24]

Answer:

200

Step-by-step explanation:

Let number of tickets sold before game be x while those at the gate be y

Total tickets sold are 600 hence x+y=600

Cost of tickets

Total amount collected is $700 hence

x+1.5y=700

x+y=600

x+1.5y=700

Subtracting equation 1 and 2

0.5y=100 hence y=200

the ratio of the number of goat to the number of sheep is 3:1. The sheep are 10 in numbers. how many goats are in the gardens an
ValentinkaMS [17]

Answer:

30 goats, and 40 animals

Step-by-step explanation:

so since the problem says 10 goats are in the garden, and the ratio of sheep to goats is 3:1 you do 3*10. it's basically saying for every 1 goat you have 3 sheep. so if you take away the 0 from 30 and 10 you get 3:1. : )

The circular base of a cone has a radius of 5 centimeters. The height of the cone is 12 centimeters, and the slant height is 13
Iteru [2.4K]

Answer:

283 cm^2

Step-by-step explanation:

Solution:-

We have a cone with a circular base of radius r = 5 cm

The height of the cone is h = 12 cm

The slant height of the cone is L = 13 cm

We are to determine the surface area of the cone. The surface area of the cone is comprised of two parts:

         Base Area : Circle

               A_1 = \pi r^2\\\\A_1 = \pi 5^2\\\\A_1 = 25\pi

        Curved Surface: conical

                A_2 = \pi * r*L\\\\A_2 = \pi * 5*13\\\\A_2 = 65\pi

The total surface area of the cone can be written as ( A ):

               A = A_1 + A_2\\\\A = (25 + 65 )*\pi \\\\A = 90*(3.14) \\\\A = 282.7433 cm^2

Answer: The surface area of the cone to nearest whole number would be 283 cm^2
