Answer:
31.41 ft²
Step-by-step explanation:
Heron's formula is useful when you have the three side lengths.
A = √(s(s -a)(s -b)(s -c)) . . . . sides are a, b, c and s = (a+b+c)/2
Using the given side lengths, we have ...
s = (8 +8.4 +13.5)/2 = 29.9/2 = 14.95
A = √(14.95(14.95 -8)(14.95 -8.4)(14.95 -13.5)) = √(14.95×6.95×6.55×1.45)
A = √986.81399375 ≈ 31.41 . . . . square feet
Answer:
d
Step-by-step explanation:
You didn’t attach the line plot but I’ll do my best.
1 pound = 16 ounces
It says of a pound dog toys, meaning that we will have to do multiplication:
1/2 * 1 pound
= 1/2 * 16 ounces
= 8 ounces
5/8 * 16 ounces
= 10
Next, find the difference:
10 - 8 = 2
The total weight of 5/8 of a pound of dog toys is 2 ounces greater than 1/2 of a pound of dog toys.
Also, the last bit of the question is worded incorrectly. 5/8 > 1/2 right off the bat. I’m not sure who designed the question but I think you should let them know since it would likely confuse individuals who encounter this question. Hope this helps!
I’m pretty sure the answer would be B
