Erika pays $35.70 for 15 pounds of ground beef. Calculate the price per pound. Question 4 options: $2.38 $1.79 $20.70 $1.38

$2.38

Step-by-step explanation:

Divide 30.70 by 15

$2.38

Step-by-step explanation:

This question is pretty simple but the wording can make it tricky. All it is, is a simple division problem. If there are 15 pounds of beef and in total it costs $35.70, you would take the total and divide it by 35.70. So 35.70/15=$2.38

Hope this helps!

something that characterises a right triangle is the fact that we may use pythagoras' theorem to find any one of its sides given that we have the length of the other two sides. here, we have the length of the hypotenuse, √(87) yd, and one other side, √(23) yd, thus we can easily find the length of the remaining side using pythagoras' theorem as defined below:

c^2 = a^2 + b^2, where c is the length of the hypotenuse, and a and b are the lengths of the other two sides.

thus, given that c = √(87) and a = √(23), we may substitute these into the formula we defined above to get:

c^2 = a^2 + b^2

(√87)^2 = (√23)^2 + b^2 (substitute c = √87 and a = √23 into the equation)

87 = 23 + b^2 (evaluate (√87)^2 = 87 and (√23)^2 = 23 - remember that the square root of a number, squared will equal that very same number)

64 = b^2 (subtract 23 from both sides)

√64 = b (take the square root of both sides)

8 = b (evaluate √64 = 8)

therefor, the length of the unknown leg in the right triangle is 8 yd (first answer).
