$rectangle \: area \: = \: len \: \times width \: \\ = 12ft\times 18ft \\ = 216 \: ft ^{2}$

$sq \: area \: = ( one \: side)^{2} \\ = (13ft)^{2} \\ = 169ft^{2}$

Expression

 $cost \: = 169(3.50) + 216(3.50) \:$

scoundrel [369]

Answer:

Adult is $12 and child is $7

Step-by-step explanation:

Adult=x and Children=y

first day: 4x+1y=55

second: 3x+2y=50

Get one letter the same but opposite

(4x+1y=55) times that by -2

-8x+-2y=110

3x+2y=50

minus all of that u get

-5x=60

divide 60 by 5

x=12

fill in X

3(12)+2y=50

36+2y=50

-36 -36

2y=14

Help me with this please.

Flura [38]

Answer:

Step-by-step explanation:

Points A,B ,C are all to the left of 0 so they are negative

We want a point -3 1/2

The points A and B are to the left of -3 so they are more negative than -3

A is at -5 so it cannot be -3 1/2

$\huge \boxed{\mathfrak{Question} \downarrow}$

Evaluate the expression ⇨ (-6) squared.

$\large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}$

$\sf (-6) \: squared$

This will be equal to..

$\sf( - 6 ) ^ { 2 }$

Multiply -6 by itself (squaring a number means to multiply the number by itself twice)

$\sf- 6 \times - 6 \\$

-6 multiplied by-6 will get you 36 as the answer.

$= \boxed{\boxed{\bf \: 36}}$

Find the surface area of the attached figure and round your answer to the nearest tenth, if necessary.

mariarad [96]

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

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

$= 81 + 18*9.2$

$= 81 + 165.6$

$S.A = 246.6 in^2$
