Answer:

The answer is the square pyramid.

Step-by-step explanation:

The square pyramid is a solid figure that its base is a square and his height is conformed of four face which converge to one point.

I have attached an image that shows a square pyramid and a counting of every edge and vertice.

The rectangular prism and the pentagonal prism have more edges and vertices. On the contrary, the triangular pyramid has less vertices and edges.

The sum of three numbers is 103. The second number is 5 less than the first. The third number is 4 times the first. What are the

madreJ [45]

Answer:

The numbers are 18, 13, and 72.

Step-by-step explanation:

Let the three numbers be represented by <em>a, b</em>, and <em>c</em>.

The sum of the three is 103. Thus, we can write that:

$a+b+c=103$

The second number is five less than the first. So:

$b=a-5$

And the third number is four times the first. So:

$c=4a$

Substitute:

$a+(a-5)+(4a)=103$

Solve for <em>a</em>. Combine like terms:

$6a-5=103$

Add five to both sides:

$6a=108$

And divide both sides by six. Therefore:

$a=18$

So, the first number is 18.

Since the second number is five less than the first, the second number is 13.

And since the third number is four times the first, the third number is 72.

When the net is folded up, which sides will touch?

Tresset [83]

<h3>Answer: Choice C is correct</h3>

Explanation:

We can think of the square in the middle of the four others as the floor

The surrounding four squares are the walls that fold upward.

The square at the very right side will then form the ceiling.

Side E and side L join at the top left edge.

See the diagram below.

x^2-10x+16=0. s=-10

x^2-8x-2x+16=0. p=16

x(x-8)-2(x-8)=0. [-8,-2]

(x-2)(x-8)

Can somebody please help me with this ?? :)

Neko [114]

The equation is: 3x^3 = 4x + 8

The form is ax^2 + bx + c = 0

Rewrite the given equation to equal 0:

Subtract 3x^2 from both sides to get:-3x^2 + 4x + 8 = 0

Now give each letter their value:

a = -3, b = 4, c = 8

The price of a holiday was decreased by 12% to £600. What was the price before the decrease?

Inessa [10]

Answer:

The original price of the holiday was $ 681.81.

Step-by-step explanation:

As the price of the holiday was reduced by 12% to a value of $ 600, it can be said that this price is 88% of its original price (100 - 12). Therefore, to determine the original price of the holiday, it is necessary to perform the following calculation:

88 = 600

100 = X

(100 x 600) / 88 = X

60,000 / 88 = X

681.81 = X

Therefore, the original price of the holiday was $ 681.81.
