360 = 0.2 a
a = 360 / .2 = 5(360)= 1800 audience members
Q19
Assuming the information is consistent we ignore the trapezoid; we have two triangles base 1.1 height 3.8 so the area for the pair is 2 (1/2) (1.1) (3.8) = 4.18 sq inches.
Q20
6(5)^2 - 5(4) + 8 = 6(25) -20 + 8 = 150 - 20 + 8 = 138
Q21
This is an LCM or least common multiple problem
LCM(12,8) = LCM(3(4),2(4))=3(2)(4)=24 weeks
Answer:
-9
Step-by-step explanation:
Substitute 3 for <em>z</em><em> </em>and 9 for <em>w</em> in the equation.
we can use
volume of cone formula
where
r' is radius of cone
h' is height of cone
we are given
The radius of the cone is half the radius of the cylinder
so,
The height of the cone is equal to the radius of the cylinder
so,
now, we can plug values into formula
we get
we can simplify it
so, option-C.........Answer
We need 6.5% to a decimal so..
6.5% /100 = 0.065
$21.30 X 0.065 = 1.3845 tax on the shirt
So.. we add the price of the shirt, and the amount of tax on the shirt
$21.30 + 1.3845 = $22.6845
Answer = $22.68
Answer:
y < 3/2x - 5/2 or y < 3/2 x - 2.5
Step-by-step explanation:
3x -2y > 5
Solve for y
3x - 2y > 5 when solving a problem with an inequality sign, rewrite the problem and solve with an equal sign and add the equality at the end.
3x - 2y = 5
-2y = -3x + 5
y = -3/-2x+ 5/-2
y = 3/2x - 2 1/2
Now if you have to use the inequality sign, you will use < because the y term was negative and that will change the direction of the inequality sign.
So y < 3/2x - 5/2 or y < 3/2 x - 2.5
