Step-by-step explanation:
The angles line up~ P is the same as angel I.
Two gears are connected and are rotating simultaneously. The smaller gear has a radius of 2 inches, and the larger gear has a radius of 7 inches.
Part 1: What is the angle measure, in degrees and rounded to the nearest tenth, through which the larger gear has rotated when the smaller gear has made one complete rotation?
Part 2: How many rotations will the smaller gear make during one complete rotation of the larger gear?
Show all work.
Answer:
Let r represent the radius of the smaller circle and R the radius of the larger circle.
Apply ratios: the radius of smaller circle to radius of larger circle, i.e.
r: R = 3 : 7.
I complete rotation = 360 degrees.
Part 1:
For one complete rotation of the smaller circle, the larger circle is rotated through: (3/7)*(360) = 154.3 degrees
Part 2:
For one complete rotation of the larger circle, the larger circle is rotated through: (7/3)*(360) = 840.0 degrees
This is equivalent to (840/360) = 2.3 rotations
Alternatively, use the ratios:
The number of rotations = R/r = 7/3 = 2.3 rotations

Answer:
Step-by-step explanation:
for smaller gear circumference=2π×2=4π inches
for larger gear
l=4π
θ=l/r
θ=(4 ×180)/7=720/7=102 .9°
for larger gear circumference=2π×7=14π
number of rotations=(14π)/4π=7/2=3.5 rotations or 3 1/2 rotations.
Solve the system of equations:
4x - 3=-2x + 9
Answer:
x=2
Step-by-step explanation:
Step 1: Add 2x to both sides.
4x−3+2x=−2x+9+2x
6x−3=9
Step 2: Add 3 to both sides.
6x−3+3=9+3
6x=12
Step 3: Divide both sides by 6.
6x = 12

write a equation of the line that passes through each pair of points (1,0) (5,-1)
Answer:
Slope : -1/4
Equation: y = -x + 1/4
Step-by-step explanation:
You start by finding the slope using the slope formula. Then after finding the slope you use one of the pairs to substitute in the equation y = mx+b then after doing that you solve for your b since it will be the only missing variable. Then you have your equation.

Extra Example 3: Hazel has $23.28 in her purse. She has $5.60 more than Nixon.
Paul says that Nixon has $28.88. Yolanda says that Nixon has $17.68. Who is
correct?
Answer:
Yolanda is correct.
Step-by-step explanation:
If Hazel has $23.28 and $5.60 more than Nixon, then Nixon will have $17.68 because 23.28-5.60 is 17.68.
The only way Paul would be right is if Nixon has $5.60 more than Hazel because 23.28+5.60 is 28.88.

Simplify fully 4a sqaured +8a +2 I-a squared +9a -3
Answer:
The simplified expression is: [tex]3a^2 + 17a - 1[/tex]
Step-by-step explanation:
We are given the following expression:
[tex]4a^2 + 8a + 2 - a^2 + 9a - 3[/tex]
We can fully simplify the expression by combining the like terms. So
[tex]4a^2 + 8a + 2 - a^2 + 9a - 3 = 4a^2 - a^2 + 8a + 9a + 2 - 3 = 3a^2 + 17a - 1[/tex]
The simplified expression is: [tex]3a^2 + 17a - 1[/tex]

The game is used in a school to rasie money for charity. Each player pays 30p to play this game. To win a bag of crisps players have to sxore exactly 7. Each bag of crisps cost the school 20p. How much should the school expect to raise for charity if 60 peoples played the game
Answer:
The answer is "1500p".
Step-by-step explanation:
The given probability is = 7. so, https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B12%7D%20%5C%20%3D%20%5Cfrac%7B1%7D%7B4%7D

But, https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B4%7D its side will survive = 30 people, as well as the school would have to invest https://tex.z-dn.net/?f=%5C%2030%20%5Ctimes%20%5C%2030p%20%5C%20%3D%20%5C%20900p

The school can expect to raise approximately £85.71 for charity if 60 people played the game.
If each player pays 30p to play the game, and 60 people played the game, the total amount raised by the school would be:
Total amount raised = Number of players * Cost per player
Total amount raised = 60 * 30p
Now, let's calculate the cost of the crisps won by the players:
Cost of crisps won = Number of crisps won * Cost per crisp
Since each bag of crisps costs 20p, and players have to score exactly 7 to win a bag of crisps, we need to determine the number of bags of crisps won.
To find the number of bags of crisps won, we divide the total number of players by the number of players required to win a bag of crisps:
Number of bags of crisps won = Number of players / Number of players required to win a bag of crisps
Number of bags of crisps won = 60 / 7
Now, we can calculate the cost of the crisps won:
Cost of crisps won = Number of bags of crisps won * Cost per crisp
Cost of crisps won = (60 / 7) * 20p
Finally, to determine the amount the school expects to raise for charity, we subtract the cost of the crisps won from the total amount raised:
Amount raised for charity = Total amount raised - Cost of crisps won
Amount raised for charity = 60 * 30p - (60 / 7) * 20p
To simplify the calculation, we can convert the pence to pounds by dividing by 100:
Amount raised for charity = (60 * 30) - (60 / 7) * 20 = £(1800 - (1714.2857))
Amount raised for charity ≈ £85.71 (rounded to two decimal places)
Therefore, the school can expect to raise approximately £85.71 for charity if 60 people played the game.

The Dial and the Lewis families when to Taco Box for dinner. The Dials bought 3
burrito meals and 4 taco meals for $48. The Lewis' bought 6 burrito meals and 2
taco meals for $60. How much does a burrito meal cost? How much does a taco
meal cost?
Answer:
A burrito costs $8, while a taco costs $6.
Step-by-step explanation:
Given that the Dial and the Lewis families when to Taco Box for dinner, and the Dials bought 3 burrito meals and 4 taco meals for $ 48, while the Lewis' bought 6 burrito meals and 2 taco meals for $ 60, to determine how much does a burrito meal cost and how much does a taco meal cost make the following calculations:
3B + 4T = 48
3B = 48 - 4T
6B + 2T = 60
6B = 60 - 2T
3B = 30 - 1T
30 - 1T = 48 - 4T
30 = 48 - 4T + 1T
30 - 48 = -3T
-18 = -3T
-6 = -T
6 = T
3B + 4x6 = 48
3B + 24 = 48
3B = 24
B = 24/8
B = 8
6x8 + 2x6 = 60
48 + 12 = 60
60 = 60
Thus, a burrito costs $ 8, while a taco costs $ 6.
