Answer:-5
Step-by-step explanation:
Number of adults with ticket = 17
Total number of people interviewed = 50
Relative frequency of adults with ticket = 17 / 50 = 0.34
Think about it. The 80 is the y-intercept meaning that is the starting point or starting height where the rocket is launched from. The purpose of the expression is to show the height of the rocket over time.
I have to edit your expressions. If do not guess the right expressions you can do the maths because I will give you the procedure step by step.
1) Dimensions: 2x, 5x + 3, 3x + 1.
2) Volume of water: 22x^3 + 18x^2 + 3x [I changed the exponent of 18x^3 to 18x^2 because I think there was a mistake]
3) Calculations:
Volume of the tank = (2x)(5x+3)(3x+1) = 2x(15x^2+5x+9x+3) = 2x(15x^2+14x+3) =
= 30x^3+28x^2+6x
Volume of water = 22x^3 + 18x^2 + 3x
Volumen of the block = volume of tank - volume of water =(30x^3+28x^2+6x) - ( 22x^3 + 18x^2 + 3x) = 30x^3 +28x^2 +6x -22x^3 -18x^2 -3x =
= 8x^3 + 10x^2 + 3x
Now we can factor this last polynomial:
x(8x^2 + 10x +3) =x(2x+1)(4x+3).
The the dimensions of the metal block are x, 2x+1, 4x+3
Answer:
84 mm^2
Step-by-step explanation:
using the formula area of a triangle which is A=bxh/2
substitute b with 24 and h with 7
A=24x7/2
multiply
A=168/2
and then divide by 2
A=84
