James piglet weighs 7 lb his hand weighs 74 oz how many more ounces does the piglet weigh than the hen​
zavuch27 [327]

Answer:

38 more ounces.

Step-by-step explanation:

First, convert the 7 lbs. to ounces by multiplying 7 by 16. You do this because 1 pound equals 16 ounces. You get 112 ounces. Then subtract the hand's weight (74 oz.) from the piglet's weight (112 oz.).  You get 38 ounces which is your answer.

Given: KLMN is a trapezoid m∠K = 90°, m∠N = 45° LK = LM = 10 Find: KN, Area of KLMN
Ilya [14]
Let KLMN be a trapezoid (see added picture). From the point M put down the trapezoid height MP, then quadrilateral KLMP is square and KP=MP=10.
A triangle MPN is right and <span>isosceles, because
</span>m∠N=45^{0}, m∠P=90^{0}, so m∠M=180^{0}-45^{0}-90^{0}=45^{0}.Then PN=MP=10.
The ttapezoid side KN consists of two parts KP and PN, each of them is equal to 10, then KN=20 units.
Area of KLMN is egual to A= \frac{LM+KN}{2} *MP= \frac{10+20}{2} *10=150 sq. units.
