Answer:

S.A = 246.6 in^2

Step-by-step explanation:

The figure given above is a square pyramid, having a square base and 4 triangular faces on the sides that are of the same dimensions.

Surface area of the square pyramid is given as: B.A + \frac{1}{2}*P*L

Where,

B.A = Base Area of the pyramid = 9*9 = 81 in²

P = perimeter of the base = 4(9) = 36 in

L = slant height of pyramid = 9.2 in

Plug in the values into the given formula to find the surface area

S.A = 81 + \frac{1}{2}*36*9.2

= 81 + 18*9.2

= 81 + 165.6

S.A = 246.6 in^2

MissTica

Answer:

<h2>$4.7</h2>

Step-by-step explanation:

step one:

Let the cost be y

to solve for the cost of  a movie ticket, we need to solve the expression

y=2.75+0.10x

step two:

given that x is the number of years between 1980-2000

the number of years is 20years

put x= 20 in the expression for the cost we have

y=2.75+0.10(20)

y=2.7+2

y=$4.7

What is<br> 12,4% expressed as a fraction?
Oliga [24]

Answer:

Well, you first want to find out what it is in decimal form, which in this case is 0.124. Then once you do that, you can convert it to an improper fraction, which would be 124/100, you then can simplify it to convert it into a mixed number, which lands you the final answer of 1 6/25 I hope this helps you! :)

tangare [24]

Answer:

14.285714285714 %

Step-by-step explanation:

suppose the weekly payment is of x dollars

Then

Previous payment : $(x/40) per hour

New payment : $(x/35) per hour

Then

The percentage increase in the hourly rate of pay is :

=\frac{\frac{x}{35} -\frac{x}{40} }{\frac{x}{40} } \times100

=\frac{\frac{5x}{1400} }{\frac{x}{40} }  \times100

=\frac{5x}{1400} \times \frac{40}{x} \times100

=\frac{200}{1400} \times100

=\frac{1}{7} \times100

=14.285714285714
