60° 10 in
Area of sector would be,
⇒ Area of sector = 102.6 feet squared
We have to given that,
Radius of circle = 14 ft
Angle θ = 60°
Now, We know that,
Area of sector = [θ/360]πr²
Where, r is radius of circle.
Hence, We can substitute all the values, we get;
Area of sector = [θ/360]πr²
Area of sector = [60/360](22/7)(14)²
Area of sector = [1/6][22/7][196]
Area of sector = 102.6 feet squared
Thus, Area of sector would be,

Amelia grabbed 50% of the M&M's from a bowl. Then, Jess took 50% of what was left. Dominick takes 50% of the remaining M&M's. There were 3 left. How many M&M's were in the bowl before Amelia arrived.
The number of M&M's that were in the bowl before Amelia arrived is; 12
How to solve Percentage problems?Let the original amount in the bowl be x. Thus;
If Amelia grabbed 50%, then amount left = (100% - 50%)x = 50%x = 0.5x
Now, we are told that domicick took 50% of what was keft after amelia. Thus; New amount left = 100%x - (0.5x + 0.25x) = 0.25x
Now, we are told that there were finally 3 left after all the deductions. Thus;
0.25x = 3
x = 3/0.25
x = 12

Answer:-60
Explanation:-Please look at the attached picture :)
We are given with a expression (x + 1)² - 4 and we need to find it's value when x = 7 . So , Let's name this polynomial first, let's say that p(x) = (x + 1)² - 4 . Now ;

The y-coordinate of point P is 1.To find the y-coordinate of the point P on the parabola y = 3x^2 - 11x + 10 where the slope is 7, we can differentiate the equation to find the derivative. The derivative of y = 3x^2 - 11x + 10 is y' = 6x - 11.
To find the x-coordinate of point P, we can set the derivative equal to the given slope: 6x - 11 = 7. Solving for x, we get x = 3.
To find the y-coordinate of point P, we substitute the x-coordinate back into the original equation: y = 3(3^2) - 11(3) + 10. Simplifying, we find y = 1.
Therefore, the y-coordinate of point P is 1.

What are equations?A mathematical equation is a formula that uses the equals sign to represent the equality of two expressions.
a formula that expresses the connection between two expressions on each side of a sign.
Typically, it has a single variable and an equal sign.
Like this: 2x - 4 = 2.
In the above example, the variable x exists.
So, the equation represents the number of people who can go to the park:
The total budget is $114.75.
Parking costs $8.75.
The cost of a ticket per person is $26.50.
So form the equation:
Let, a be the number of people and C be the total cost.
8.75 + 26.50a = C
Now, let a be 4.
8.75 + 26.50a = C
8.75 + 26.50(4) = C

Decide whether the rates are equivalent. Maria saves $50 in 4 months.
Ralph saves $60 in 5 months
Answer:
The rates are not equivalent since Maria saves $0.50 more per month than Ralph.
Step-by-step explanation:
We can determine if two rates are equivalent by comparing the rates at which they save per month.
Maria's savings per month:
Both 50 and 4 can be divided by 2, which gives us 25/2. As a regular number, this becomes 12.5/1 which means Maria saves $12.5 per month.
Ralph's savings per month:
Both 60 and 5 can be divided by 5, which gives us 12. Thus, Ralph saves $12 per month.
Thus, the rates are not equivalent as Maria saves $0.50 more per month than Ralph.

A cell phone plan costs $29.70 per month for 600 minutes of talk time. It costs an additional $0.08 per minute for each minute over 600 minutes. To get e-mail access, it costs 30% of the price for 600 minutes of talk time. Your bill, which includes e-mail, is the same each month for 6 months. The total cost for all months is $267.66 Write and solve an equation to find the number of minutes of talk time you use each month.
267.66=6(0.08m+29.70+0.30(29.70))
You use___ minutes of talk time each month.
The number of minutes of talk time used each month is approximately 92 minutes.
What is Equation ?
In mathematics, an equation is a statement that asserts the equality of two expressions, which are usually denoted by variables. An equation typically contains one or more variables, coefficients, and mathematical operations such as addition, subtraction, multiplication, division, and exponentiation.
Let's break down the equation provided to understand how it was derived:
The cost for each month includes three components: the base cost of $29.70, the cost for any minutes over 600, and the cost for email access (which is 30% of the price for 600 minutes of talk time).
The cost for any minutes over 600 is $0.08 per minute.
The total cost for all months is $267.66.
We want to find the number of minutes of talk time used each month, represented by "m".
Putting this all together, we get the equation:
Total cost for 6 months = 6 x (cost per month)
$267.66 = 6 x ($29.70 + $0.08 x (m - 600) + 0.3 x $29.70)
Simplifying this equation, we get:
$267.66 = $178.20 + $1.44m - $43.47
$1.44m = $132.93
m = 92.24 (rounded to the nearest minute)
Therefore, the number of minutes of talk time used each month is approximately 92 minutes.
