Answer:

13260 square inches

Step-by-step explanation:

In DEF e = 100 inches f = 740 inches and angle D = 159°. Find the area of DEF to the nearest square inch

The formula to solve the above question is

1/2absinθ

a = 100 inches

b = 740 inches

θ = 159°

The area of the triangle =

1/2 × 100 × 740 × sin 159°

= 13259.61 square inches

Approximately = 13260 square inches

Therefore, the area of DEF = 13260 square inches

sweet-ann [11.9K]

Answer:

2 x 10^6

Step-by-step explanation:

10^6 = 1,000,000

2 x 1,000,000 = 2,000,000

10^5 = 100,000

9 x 100,000 = 900,000

2,000,000 > 900,000

Jayden and Carson are selling T-shirts and sweatshirts for a fundraiser. Jayden sells 9 T-shirts and 3 sweatshirts for $420. Car
Lynna [10]

Answer:

9t + 3s = 420

t + 6s = 296

s =44; t = 32

Step-by-step explanation:

Let

Price of a T-shirt = t

Price of a sweatshirt = s

Jayden:

9t + 3s = 420

Carson:

t + 6s = 296

9t + 3s = 420 (1)

t + 6s = 296 (2)

From (2)

t =296 - 6s

Substitute t =296 - 6s into (1)

9t + 3s = 420 (1)

9(296 - 6s) + 3s = 420

2664 - 54s + 3s = 420

2,664 - 51s = 420

-51s = 420 - 2,664

-51s = -2,244

s = 44

Substitute s = 44 into (2)

t + 6s = 296

t + 6(44) = 296

t + 264 = 296

t = 296 - 264

t = 32

s =44; t = 32
