Answer:. If the Area is 177, it should have been given in square centimeters.
If one side is 13 cm, the other side is about 13.6cm.
If one side is 11 cm, the other side should be about 16.1 cm. Even the choice is incorrect!
A/x = w
Step-by-step explanation: to find a side when the Area is given, divide the Area by the length or width given.
It's an irrational number.
You can cross off terminating and repeating decimal so you're left with a rational or irrational number. A rational number is something that can be put into fraction form and/or have repeating or terminating decimals.
So our answer would be irrational.
Answer:
N+F=42 & F+3N=70 System Solved: Natalie is 14 and Fred is 28
Step-by-step explanation:
Using variables N=natalies age and F=Freds age
N+F=42 ----> N=42-F (take this and plug it into the other equation)
F+3N=70 so F+3(42-F)=70 [simplify] F+126-3F=70 [further simplify]
-2F=-56 [divide -56 by -2] F=28 [then plug this number into the orig. equation]
So N+28=42 or N=14.
Answer:
(C) y= 2.11x
Step-by-step explanation:
Set up a proportion. 6/10 = 9/x. cross multiply so x times 6 = 6x. And 10 times 9 = 90. so 6x=90. Then 90 and 6x divided by 6. which gets you x=15. The 9 ft tall elephant will cast a 15 ft shadow.
