Answer:115.4685yd^3
Step-by-step explanation:
Volume of cone=1/3πr2h
V=1/3×3.142×3.5yd×3.5yd×9yd
V=115.4685yd^3
Answer:
4:1 ( i think)
Step-by-step explanation:
We can solve for a and b using substitution
a-b=3
a+b=5
solve and get that a=4 b=1
Which means that it's a 4:1 ratio
For a pear, it would be 3/16 of a chance. For an orange, it would be 1/4 of a chance.
Answer:
14, 21, and 63
Step-by-step explanation:
we can set the three unknown numbers as x, y, and z
so
x + y + z =98
now we are given that the first (x) is seven less than the second (y)
x = y - 7
the third number (z) is three times the second (y)
z = 3y
since we have an equation for z and x in terms of y, we can plug it into the first equation and solve for y.
(y-7) + y + (3y) =98
y - 7 + y + 3y =98
y + y + 3y =105
5y = 105
y=21
now that we know y, we can plug its value into either the second or the third equation to find x or z (I chose to find z first)
z = 3y
z = 3(21)
z = 63
now we can plug in y to find x
x = y - 7
x = 21 - 7
x = 14
so the three numbers should be 14, 21, and 63

Sorry if it's not right. But it's worth a go!
