Answer:
280
Step-by-step explanation:
V=Bh
V=1/2(7x10)8 *it is a triangluar pyrmid so the base is a triangle*
V=1/2x70x8
V=35x8
V=280
Answer:280
Let
x--------> the border’s length
y--------> the border’s width
P--------> perimeter of the border
we know that
x=5+y------> equation 1
P=2*[x+y]-----> P=2x+2y
P <=180 ft
(2x+2y) <= 180-------> equation 2
substitute the equation 1 in equation 2
2*[5+y]+2y <= 180
10+2y+2y <= 180
4y <= 180-10
4y <=170
y <=42.5 ft
so
the maximum value of the width is 42.5 ft
for y=42.5 ft
x=42.5+5------> x=47.5 ft
the answer is
the width of the border is less than or equal to 42.5 ft
I did where you subtract 4 from both sides then divide 2 from 4 and you get 0.5 as x for your answer but im not sure
Answer:

Step-by-step explanation:
Answer:
12/3=4
Step-by-step explanation:
it's 4, 2/3's stay the same. do the reciprocal on 1/6 which will be 6/1 and multiply
2/3(6/1)=12/3
and turn it to a mixed fractions and you would get 4
