The area of a square quilt is 289 square inches. There is a smaller square patch on the quilt with an area of 121 square inches.
alisha [4.7K]
Area of a square quilt = 289 square inches
Area of a smaller square quilt = 121 square inches

Area of a square = a²

Side length of big square quilt = √289 in² = 17 inches
side length of small square quilt = √121 in² = 11 inches

Perimeter of big square = 17 inches * 4 = 68 inches
perimeter of small square = 11 inches * 4 = 44 inches

difference = 68 inches - 44 inches = 24 inches.

A number a decreased by 7 is 2.
umka21 [38]

Answer:

9

Step-by-step explanation:

Let's first convert this to numbers. When a number is decreased by a certain amount, that is the same as saying that something is subtracted from it. Therefore:

a-7=2

Add 7 to both sides:

a-7+7=2+7

a=9

Hope this helps!

Write an exponential function in the form y=ab^x that goes through points (0,7) and (5,1701).
Marizza181 [45]

Answer:

y = 7 3^{x}

Step-by-step explanation:

Use the given ordered pairs to find a and b

Using (0, 7 ), then

7 = a b^{0} ( b^{0} = 1 ), thus

a = 7

y = 7 b^{x}

Using (5, 1701 )

1701 = 7 b^{5} ( divide both sides by 7 )

243 = b^{5} ( take the fifth root of both sides )

b = \sqrt[5]{243} = 3 , thus

y = 7 3^{x}
