The surface area of the square pyramid is, A. 80 in².

A three-dimensional figure is a pyramid. Its base is a flat polygon. The remaining faces are all triangles and are referred to as lateral faces.

The number of sides on its base is equal to the number of lateral faces. The line segments that two faces intersect to form its edges. The intersection of three or more edges forms a vertex.

The given figure is a pyramid having a square base.

The pyramid also has four triangular faces, each having a base of 5 in and a height of 8 in.

Therefore, the surface area of the pyramid is,

= 4[(1/2)×5×8] square inches.

= 80 in².

Answer:

it will be triangular prism

Step-by-step explanation:

rectangle

= 15.3 × (8.2 - 5.7 )

= 15.3 × 2.5

= 38.25

triangle

= 1/2 × (15.3 - 5.1+6.7) × 5.7

= 1/2 × 3.5 × 5.7

= 1/2 × 19.95

Answer: Mary is 36 and her son is 12; in 12 years her son will be 24 and she will be 48

Step-by-step explanation:

Answer:

Mary's age = 36

Son's age = 12

Step-by-step explanation:

Let x be age of Mary and y be age of her son.

According to question,

x = 3y...........(1)

And,

x + 12 = 2(y + 12)

x + 12 = 2y + 24

Replacing value of x from (1),

3y + 12 = 2y + 24

3y - 2y = 24 - 12

y = 12

And x = 3 x 12 = 36

Answer:65

Step-by-step explanation:

Answer:

0.00000002

Step-by-step explanation:

Let the unknown number be x.

Translating the word problem into an algebraic expression, we have;

2 * 10¹⁴ * x = 4 * 10⁶

To find the value of x;

x = 4 * 10⁶/2 * 10¹⁴

x = 2 * 10^{-8}

Therefore, the value of 2 x 10¹⁴ is 0.00000002 times the value of 4 x 10⁶

Total number courses, n = 10

The largest number of menu the chef can plan using his 10 main courses.

There are various combinations of menu obtainable from the available courses :

Ranging from :

nC0 to nCn

The largest number of menu he can plan is the highest output obtainable between :

10C0 to 10C10

10C0 = 1

10C1 = 10

10C2 = 45

10C3 = 120

10C4 = 210

10C5 = 252

10C6 = 210

10C7 = 120

10C8 = 45

10C9 = 10

10C10 = 1

Hence, the largest number of menu he can plan using his 10 main courses is 252

(7x+5)(7x-5)

Step-by-step explanation:

We can use the difference of squares equation which states that when a number is multiplied like: (ax+b)(ax-b) then it equals (ax-b). In this equation, since there is no "b" in the typical ax^2+bx+c, we can recognize that the answer is not a square, but a difference of squares.

Answer:

4 × 10²

Step-by-step explanation:

16 x 10^5 ÷ 4 x 10³ = 4 × 10²

4 * 10² is the number when multiplied to 4 * 10³ gives 16 * 10⁵

To divide exponents (or powers) with the same base, subtract the exponents.

Division is the opposite of multiplication, so it makes sense that because you add exponents when multiplying numbers with the same base, you subtract the exponents when dividing numbers with the same base.

The given expression is

4 * 10³ multplies with   ____ =   16 * 10⁵

We have to solve this ,

Let the number be x

4 * 10³ multplies with   __x__ =   16 * 10⁵

x = (16 * 10⁵ )/(4 * 10³)

x= ( 4²  * 10⁵ )/(4 * 10³)

Therefore the numerator and denominator has the same base so

[tex]\rm 4^{2-1} \times 10^{5-3}\\\\\\4^{1} \times 10^{2}\\\\\\4\times 10^{2}[/tex]is the number that when multiplied to   4 * 10³  gives  16 * 10⁵
