The length of a rectangular floor is 2 feet more than the width. The area of the floor is 168 square feet. Kim wants to use a ru

defon

The area of the rectangular is expressed in the formula A = l*w where l is the length and w is the width. from the first satement, l = 2 + w; then A = (2+w)*w = 2w + w^2. If A is equal to 168, then w should be equal to 12 feet and l is equal to 14 feet. Hence the width due to the border limits is 12- 2*2 equal to 8 feet

Megan buys a 2-quart bottle of juice for $2.56. What is the unit rate of the cost of the juice?

Mila [183]

Answer: $0.04 per fluid ounce.

Step-by-step explanation:

Let's conver 2 quarts to ounces, as following:

$(2\ quarts)(\frac{32\ ounces}{1\ quarts})=64\ ounces$

You know that she buys a 2-quart bottle of juice (or 64 ounces) for $2.56, therefore, to find the unit rate of the cost of the juice you must divide $2.56 by 64 ounces.

Then, you obtain the following result:

$=\frac{2.56dollars}{64\ ounces}=0.04\frac{dollars}{ounces}$

( $0.04 per fluid ounce)

bonufazy [111]

Answer:

d = 9√2

Step-by-step explanation:

$d=\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}\\\\d=\sqrt{\left(4-\left(-5\right)\right)^2+\left(-2-7\right)^2}\\\\d=\sqrt{\left(4+5\right)^2+\left(-2-7\right)^2}\\\\d=\sqrt{9^2+9^2}\\\\\mathrm{Add\:similar\:elements:}\:9^2+9^2=9^2\times\:2\\\\=\sqrt{9^2\times\:2}\\\\=\sqrt{2}\sqrt{9^2}\\\\=9\sqrt{2}$
