The gradient is the same as the slope.
The gradient is always before the x variable or is the coefficient of the x variable when an equation is in the slope intercept form.
The gradient in this equation is 1
Answer:
10.6 cones
Step-by-step explanation:
Given data
h= 4cm
d= 1.5cm
r= d/2= 0.75cm
The expression for the volume of a cone is
V= 1/3πr^2h
substitute
V= 1/3*3.142*(0.75)^2*4
V= 1/3*3.142*2.25
V=1/3*7.0695
V= 2.3565cm^3
Since the volume of 1 cone is 2.4cm^3
She can fill
=25/2.3565
=10.6 cones
About 10.6 cones
First you should find the area of the rectangle in the middle.
A: 9 x 6 = 54
Then you can find the area of the triangle on the right.
A: 6 x 5 = 30/2 = 15
Then you can do the triangle on the right.
11-9 = 2
A: 2 x 6 = 12/2 = 6
Then you can add it all together.
15 + 6 + 54 = 74
So the area of the irregular shape is 74.
I hope this helps!
Answer:
The slope is 2
Step-by-step explanation:
To find the slope given two points, we use the formula
m = (y2-y1)/(x2-x1)
= (-4--2)/(2-3)
= (-4+2)/(2-3)
= -2/-1
= 2
<span>There are 4 long rows and 5 short rows in the theater. x represents the number of chairs in each long row and y represents the number of chairs in each short row.
So, total number of chairs in 4 long rows= 4x
Total number of chairs in 5 short rows = 5y
Total number of chairs in the theater on a normal day = 4x + 5y
When 2 chairs are added to each long row, the number of chairs will change to (x+2).
So, total number of chairs in 4 long rows will be = 4(x+2)
When 3 chairs are added to each short row, the number of chairs will change to (y+3)
So, total number of chairs in 5 short rows will be = 5(y+3)
Thus, total number of chairs in the theater in rush day = 4(x+2) + 5(y+3)
= 4x + 8 + 5y + 15
= 4x + 5y + 23
Thus we can say the number of chairs increase by 23 as compared to a normal day.
