Please help.Whats thr volume of a right pyramid whose base is a square with a side 6m long and whose altitude is equal to the base side?

Answers

Answer 1
Answer:

Answer:  72\text{ cubic meters}

Step-by-step explanation:

Given: The base of the right pyramid is square with side = 6 m

Since, the altitude (h) is equals to the base , thus h=6m.

We know that the volume of the square pyramid is given by :_

\text{Volume}=(1)/(3)a^2h, where a is the side of the square.

Then, the volume of the given right pyramid is given by :_

\text{Volume}=(1)/(3)(6)^2(6)\n\n\Rightarrow\ \text{Volume}=72\text{ cubic meters}
Answer 2
Answer: V=(1/3)(area of the base)(altitude)

V=(1/3)(6²)(6)= 72 m³

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:

$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

Answers

Hello,

Please write correctly.

g(x)= (2x+3)/(x+1) to be written like a/(x+p) + q

It is very simple!

(2x+3)/(x+1)= [(2x+2)+1]/(x+1)= (2(x+1)+1)/(x+1)= 2+1/(x+1)
