70 flowers were planted in all.
Step-by-step explanation:
Let,
Tulips = t
Daises = d
Lilies = l
Total tulips planted = 42
She planted 2 times as many tulips as daises.
t=2d
Putting t=42
Dividing both sides by 2
And 3 times as many daisies as lilies.
d=3l
Putting d=21
Dividing both sides by 3
Total flowers planted = Tulips + Daisies + Lilies
Total flowers planted = 42 + 21 + 7 = 70
70 flowers were planted in all.

About 2.86 inches
Step by step explanation-
The formula for the volume of a cone is pi2 h/3 plugging the known numbers into formula you get
75=pi 5^2 h/2
H/3=0.955
H=2.86 inches
18.5-0.5= 18
18/3= 6
So r=6

Direct variation in mathematics is when two numbers are written in an equation where one of the numbers multiplied by a constant term to equal the other.
In the table in the equation, we see direct variation.
<u>X</u> <u>Y
</u><u></u>1 7
2 14
3 21
4 28
We can find the constant of the variation by dividing y by x. This constant should remain the same for all terms of x in the table with their corresponding y values.
y/x
7/1=7
14/2=7
21/3=7
28/4=7
As we can see, the values in the table all share a direct variation between x and y with the value 7.
This can be expressed in an equation: y = 7x.
