Jake and his brother, Rob, built triangular kites for the Beach Cities Kite Festival and covered them with fabric. Jake's kite is 5.5 feet long and 6 feet tall. Rob's kite is 3.5 feet long and 4 feet tall. The fabric they used costs $2.50 per square foot.How much more money did Jake spend on fabric than Rob?

Answers

Answer 1

Answer:

Answer:

$23.75

Step-by-step explanation:

Ok, first, To solve the problem, we need the amount of square feet of each kite.

To calculate area of triangles, you multiply base with height, then divide by two. (bh/2)

Jake's kite is 5.5 feet long, and 6 feet tall, so we plug this into the equation to get: (5.5 · 6)/2

we simplify to get 33/2 = 16.5 square feet.

Then to get the total cost, we multiply 16.5 with 2.50 to get $41.25, which is the cost of Jake's kite.

Now, we do the same with Rob's kite. (3.5*4)/2 = 14/2 = 7, then multiply by 2.5 to get 7 * 2.5 = $17.5, and that's the cost of Rob's kite.

To get the final answer, we subtract 41.25 to 17.5, which is $23.75

Stir-fry is tony's favorite food to cook, but it always makes a lot of smoke! Tony needs to know the volume of his kitchen so he can buy a fan that is the right size. Tony's kitchen has a floor area of 85 square feet. The height of the ceiling is 8 feet. What is the volume of tony's kitchen?

Answers

Answer:

Volume = 680 ft³

Step-by-step explanation:

Given

Floor Area = 85 ft²

Height = 8 ft

Required

Volume of the Kitchen

To solve this, it'll be assumed that Tony's kitchen has a regular shape.

Having said that, the volume of Tony's kitchen is calculated as thus.

Volume = Floor Area * Height.

Substitute the values of floor area and height

Volume = 85ft² * 8ft

Volume = 680 ft³

Hence, the volume of Tony's kitchen is 680ft³

Help please!!To solve the problem tan^-1(cos(pi/2)) find the angle in the interval [-pi/2, pi,2] whose tangent equals 0.

Answers

The cosine of pi/2 is 0 so the problem really says "find the angle between - pi/2 and pi/2 whose tan = 0. That would be the same as asking for the angle whose sin is 0. That would be 0.
