9514 1404 393

Answer:

  88 ounces

Step-by-step explanation:

Let x represent the number of ounces of the less expensive alloy in the mix. Then the cost of the mix will be ...

  6.75x +10(55) = 8(55+x)

  110 = 1.25x . . . . . . subtract 440+6.75x

  88 = x . . . . . . . . divide by 1.25

88 ounces of $6.75/oz silver must be used.

Find the area of the carpet tile. Then find the area covered by 120 carpet tiles.
weqwewe [10]

The area of the carpet is the amount of space it occupies

  • The area of the carpet tile is 256 square inches
  • The area covered by 120 tiles is 30720 squares inches

<h3>How to determine the carpet area</h3>

The dimension of the carpet tile is 16 inches by 16 inches

So, the area is:

Area = 16 * 16

Evaluate the product

Area = 256

Hence, the area of the carpet tile is 256 square inches

For 120 carpet tiles, the area is:

Area = 120 * 256

Area = 30720

Hence, the area covered by 120 tiles is 30720 squares inches

Answer:

J

-66

a1 = 2

n = 18

d = - 4

a18  =  a1 + (n - 1) * d

a18 = 2 + (18 - 1)*(-4)

a18 = 2 + 17*-4

a18 = 2 - 68

a18 = -66

Mel had some cartons of milk. He sold 2/5 of the cartons in the morning. He then sold 3/4 of the remainder in the afternoon. 24
Yuki888 [10]
Sold 2/5 in the morning.....leaving 3/5
he sold 3/4 of 3/5 in the afternoon......3/4 * 3/5 = 9/20

2/5 = 8/20
9/20 - 8/20 = 1/20...so he sold 1/20 more in the afternoon.
so if 1/20 = 24, then 20/20 = 24*20 = 480

so he started with 480 cartons
