Step-by-step explanation:
use herons formula
√s(s-a)(s-b)(s-c)
where s is the semi perimeter
S=20
and a,b,c are sides of triangle
=√20(20-17)(20-9)(20-14)
=√20.3.11.6
=62.92
nearest whole number is 63
option B is correct
"D" is the correct answer.
6(the amount of money each week) should be greater than or equal to 360.
360/6= 60
You would save 60 per week.
I hope this helps!

Let's look at the formula for the volume of a sphere:
Volume = (4/3) (pi) (radius)³ .
If you multiply the radius of a sphere by 'anything',
then the volume gets multiplied by (anything)³ .
Going the other direction, if you multiply the volume by
'something', then the radius gets multiplied by ∛(something).
In this question, the ratio of the volumes is 3 .
So the ratio of the radii (radiuses) is ∛3 = about 1.442 (rounded)
Answer:
21
Step-by-step explanation:
8x+y, when x=2 and y=5,
then 8*2+5. Because the 2 is right next to the 8, it isn't '82', but '8*2'
According to PEMDAS, multiplication is done first, so
8*2= 16,
16+5, which is 16+5= 21
