A store is giving away a $10 dollar coupon to every 7th person to enter the store and a $25 coupon to every 18th person to enter the store.

To find the first person to get both coupons, you have to find the LCM of 7 and 18. First list the multiples of each number.

7 - 7, 14, 21, 28, 35, 42, 49, 56, 63, 70, 77, 84, 91, 98, 105, 112, 119, 126, 133

18 - 18, 36, 54, 72, 90, 108, 126, 144

The common multiples are bold. The <u>126th person</u> will be the first to get both coupons.

Answer:

x = 0.75 feet

Step-by-step explanation:

The area of a square is 18/32 square foot

We need to find the side length of the square.

The area of a square of side x is given by :

$A=x^2$

Substitute all the values,

$x=\sqrt{A} \\\\x=\sqrt{\dfrac{18}{32}} \\\\x=0.75\ feet$

So, the side length of the square is equal to 0.75 feet.

Brainlist answer to whoever actually gets this right.

Murljashka [212]

Area of top triangle = 1/2(3.5)(9) = 15.75
Area of bottom left triangle = 1/2(2)(2) = 2
Area of bottom right triangle = 1/2(2)(5) = 5
Area of square = 2 x 2 = 4

Area of figure = 15.75 + 2 + 5 + 4 = 26.75

answer
26.75 units^2
