Answer:
Assuming the number is 9.094 the answer is 9.094 If it is whole number it is 9000
Step-by-step explanation:
The tens place is .0
The Hundreds place is .09
The thousands place is .094
if you are talking about whole numbers: it's 9000
When rounding, 5 and above it is rounded up, and 4 and below is rounded down.
So for this problem you only need to look one place to the right.
9<u>0</u>94 Because that number is 0 that means you round down.
Answer:
x=y+20
Step-by-step explanation:
y=x-20
Swap sides so that all variable terms are on the left hand side.
x-20=y
Add 20 to both sides.
x=y+20
Answer:
43.8°
Step-by-step explanation:
Applying,
Cosine rule,
From the diagram attached,
x² = y²+z²-2yxcos∅.................... Equation 1
where ∅ = ∠YXZ
Given: x = 8.7 m, y = 10.4 m, z = 12.4 m
Substitute these values into equation 1
8.7² = 10.4²+12.4²-[2×10.4×12.4cos∅]
75.69 = (108.16+153.76)-(257.92cos∅)
75.69 = 261.92-257.92cos∅
collect like terms
257.92cos∅ = 261.92-75.69
257.92cos∅ = 186.23
Divide both sides by the coefficient of cos∅
cos∅ = 186.23/257.92
cos∅ = 0.722
Find the cos⁻¹ of both side.
∅ = cos⁻¹(0.7220)
∅ = 43.78°
∅ = 43.8°
Volume = 12 * area of triangular base
area of triangle = 1/2 base * height = 3 * height
height = sqrt(5^2 - 3^2) = 4
area of triangle = 4*3 = 12
Vol of prism = 12*12 = 144 cubic units
