Hence Cassie need to make the model is 2250[tex]cm^{2}[/tex]

A square pyramid has a square base and four lateral faces in geometry. A pyramid is a polyhedron with a base and three or more triangular faces that meet above it . A square pyramid, also known as a pentahedron, is a three-dimensional geometry with a total of five faces.

As ancient pyramid models were in shape of square pyramid hence we apply

[tex]A = a(a + \sqrt{ (a^{2} + 4h^{2} ))}[/tex]

where a =25cm

and h=30 cm

[tex]A = 25(25 + \sqrt{ (25^{2} + 4(30^{2}) ))}[/tex]

=25(25+65)

=2250[tex]cm^{2}[/tex]

Hence Cassie need to make the model is 2250[tex]cm^{2}[/tex]

Answer:

r = 12.1

Step-by-step explanation:

r - 18.7 = -6.6

 + 18.7   + 18.7 ( add 18.7 to both sides)

r = -6.6 + 18.7

r = 12.1

Answer: 54

Step-by-step explanation:

Since the triangles are similar, the sides form s equalivent proportion. The hypotunse of the bigger triangle and the smaller triangles correspond with each other and the base of the smaller and larger triangle correspond so we use this proportion: hypo. of big triangle/ base of larger triangle= hypo of smaller triangle/ base of smaller triangle.

Let substitue: 52.5/x= 5/4: ( I  Reduce 15/12 into 5/4).Cross multiply:    210=5x: Divide by 5 both sides. x=42. Then add the 42 and and the 12 to find the whole distance which is 54.

Answer:

114 degrees

Step-by-step explanation:

From the letters that describe the rays, these two angles are adjacent to each other, and therefore, if the measure of one is 27 degrees and that of the other one is 87 degrees, then the larger angle defined by the two rays (HJ and HK) with common vertex H would be:

m<JHK = 27 degrees+ 87 degrees = 114 degrees

Answer:

2

Step-by-step explanation:

Plug in all of the values then solve using order of operations

4+(-1^2)(-2)

4+1(-2)

4+(-2)

4-2=2

Answer:

if you divide it by 2, you would have 128 slices because 256 ÷ 2 gives you 128, and when you multiply 128 by 2 you get 26.

Given:

The graph of a function.

To find:

The range of the function.

Solution:

Range is the set of y-values or output values.

From the given graph it is clear that,

[tex]f(x)\to -\infty\text{ as }x\to -\infty[/tex]

[tex]f(x)\to \infty\text{ as }x\to \infty[/tex]

And the value function can be any real number. So,

Range = [tex]-\infty<y<\infty[/tex]

Range = [tex](-\infty, \infty)[/tex]

Range = y is all real numbers.​

Therefore, the correct option is D.

Answer:

D. y is all real numbers.​

Step-by-step explanation:

Range is the set of y-values or output values.

From the given graph it is clear that,

And the value function can be any real number. So,

Range =

Range =

Range = y is all real numbers.​

Therefore, the correct option is D.

Answer with explanation:

To prove: [tex]a^2-a[/tex] is divisible by 2 for any whole value of a.

Consider [tex]a^2-a=a(a-1) \ \ \ \ [\text{ Taking 'a' out as common }][/tex]

Here, a and (a-1) are two consecutive numbers such that,

either of them must be an odd number and an even number.

i.e. a(a-1)= Product of even and an odd number = Even number  [Trivial statement]

⇒ a(a-1) is divisible by 2 [Every even number is divisible by 2.]

⇒  [tex]a^2-a[/tex] is divisible by 2 for any whole value of a.

Hence proved.
