I am not sure ...but I tried solving it
As its one significant figure you are looking at the first number and the second number. If the second number is greater than 5 then you round the first number up and vice versa. In this case there is an eight, which is bigger than 5 obviously so you round the first number to get 40000.
Answer:
1.)4188.79
2.) 7238.23
3.)1.02
4.)4189
5.)170 cm³
Step-by-step explanation:
1.) 4πr2 * 5
2.) 4πr2 * 12
3.) V = 4/3(PI*r3). *4.5
4.) V = 4/3 π r ^3 * 10
5.) Given:
Cylindrical container: height = 18 cm ; diameter = 6 cm.
3 balls each have a radius of 3 cm.
Volume of a cylinder = π r² h
V = 3.14 * (3cm)² * 18 cm
V = 508.68 cm³
Volume of rubber ball = 4/3 π r³
V = 4/3 * 3.14 * (3cm)³
V = 113.04 cm³
113.04 cm³ * 3 balls = 339.12 cm³
508.68 cm³ - 339.12 cm³ = 169.56 cm³ or 170 cm³
There is 170 cm³ free space in the container.
Answer:
x=32
Step-by-step explanation:
I believe the angles are supplementary so you could use the equation:
2x+8 + 3x+22 = 180
5x+30=180
5x=160
x=32
Answer:
x = -27
Step-by-step explanation:
Step 1 :
Equation at the end of step 1 :
(5 • (x + 3)) - 4 • (x - 3) = 0
Step 2 :
Equation at the end of step 2 :
5 • (x + 3) - 4 • (x - 3) = 0
Step 3 :
Equation at the end of step 3 :
x + 27 = 0
Step 4 :
Solving a Single Variable Equation :
4.1 Solve : x+27 = 0
Subtract 27 from both sides of the equation :
x = -27
One solution was found :
x = -27
