A group of students stood in a circle to play a game. The circle had a diameter of 11 meters. Which measurement is closest to the circumference of the circle in meters?
Answer:
Step-by-step explanation:
Given that :
Diameter of the circle = 11 cm
To obtain the Circumference ,C ; use the Relation :
2πr
Where ; r = Radius = diameter / 2 = 11/2 = 5.5m
C = 2 * 3.14 * 5.5
C = 34.54 m

Find f(5)
Answer:
f(5) = 2
Step-by-step explanation:
To evaluate f(5), that is when x = 5 in the interval x ≥ 5
then
f(5) = 6x - 28 = 6(5) - 28 = 30 - 28 = 2, so
f(5) = 2

Answer:
300 nickels
Step-by-step explanation:
Reading the question, someone has 435 nickels and dimes.
The total is $28.50.
You're trying to find how many nickels he has.
All you need to do is set up a system of equations.
I'm going to use x as the number of nickels and y as the number of dimes.
Based on the question, you can say that
x + y = 435
(the number of nickels and dimes have t equal 435)
and 0.05x + 0.1y = $28.50
(nickels are 5 cents and dimes are 10 cents)
You want to solve for x, the number of nickels.
You can manipulate the first equation by subtracting x on both sides.
After you do that, you will get y = 435 - x. Now, you can substitute this equation into the second one.
First, you can distribute the 0.1.
0.05x + 0.1(435 - x) = 28.50
Then, you can put the two x's together.
0.05x + 43.5 -0.1x = 28.50
Next, you can subtract 43.5 on both sides to isolate x.
-0.05x + 43.5 = 28.50
Finally, you can divide on both sides to get x, which is the number of nickels.
-0.05x = - 15
x = 300 nickels

Solving systems of equations using substitution/eliminationStep-by-step explanation:
Step 1: Define Systems
-6x + 5y = 34
-6x - 10y = 4
Step 2: Rewrite Systems
-6x + 5y = 34
Multiply everything by -1: 6x - 5y = -34Step 3: Redefine Systems
6x - 5y = -34
-6x - 10y = 4
Step 4: Solve for y
Elimination
Combine 2 equations: -15y = -30Divide -15 on both sides: y = 2Step 5: Solve for x
Define equation: -6x - 10y = 4Substitute in y: -6x - 10(2) = 4Multiply: -6x - 20 = 4Add 20 on both sides: -6x = 24Divide -6 on both sides: x = -4This one of the questions

Answer:
6.04 inches.
Step-by-step explanation:
Corbin want's to make a model, in which every 100 feet would be shown by 1 inch.
The monument is 604 feet in height.
Divide 604 with 100:
604/100 = 6.04
The height of Corbin's model would thereby be 6.04 inches.

Andrew wants to run ten miles in three days .He ran 212 miles on Monday and 425 miles on Tuesday how many miles does Andrew need to run on Wednesday?
Answer: 3.63 miles
Step-by-step explanation: I think you meant to type 2.12 and 4.25 so I'm just going to go by that. To figure out how many more miles he needs to run, you add the amount he already ran together, and then subtract that from his goal. 4.25 plus 2.12 equals 6.37. 10 minus 6.37 equals 3.63. He needs to run 3.63 miles on Wednesday, in order to reach his goal of 10 miles.

what is the slope and the point based on the equation: (y-2) = 5(x - 4)
Answer:
Slope = 5
Point = (4, 2)
Step-by-step explanation:
Slope: 5
Step-by-step explanation:
This is called point slope form. y-y1=m(x-x1)
If m is slope then your slope is 5
James Bond is rappelling down a cliff face to infiltrate an enemy base, but there is a gust of wind, and he starts swinging side to side. If he makes a 45 m pendulum once you factor in the length of the rope, how long does it take for him to complete a full oscillation? He'll need to know this so that he can time his distraction of the guards
Answer:
13.46 s
Step-by-step explanation:
The time it takes James Bond to complete one full oscillation is the period of a pendulum of length, l which is, T = 2π√(l/g) where l = length of pendulum = length of rope = 45 m and g = acceleration due to gravity = 9.8m/s²
So, substituting the values of the variables into the equation, we have
T = 2π√(l/g)
= 2π√(45 m/9.8m/s²)
= 2π√(4.592s²)
= 2π × 2.143
= 13.46 s
So, it takes 13.46 s for him to complete one full oscillation.
