Answer:
190 square inch
Step-by-step explanation:
Area of the partial circle = 1/2 pi r^2
Pi = 3.14
Radius r = 11 inch
Area = 1/2 x 3.14 x (11)^2
= 1/2 x 3.14 x 11 x 11
Multiply through
= 3.14 x 11 x 11 /2
= 379.94/2
= 189.97
= 190 square inch

One rotation of the carousel takes 12 seconds. How much faster does Maya travel than Kelly?
Maya travels [tex]4.19 feet/sec[/tex] faster than Kelly !
Difference in distance is : [tex]106.76-56.52 = 50.24 feet[/tex]
Step-by-step explanation:
Here we have , The Carousel in the National Mall has 4 rings of horses. Kelly is riding on the inner ring, which has a radius of 9 feet. Maya is riding on the outer ring, which is 8 feet farther out from the center than the inner ring is. We need to find In one rotation of the carousel, how much farther does Maya travel than Kelly . Let's find out:
Kelly is riding on the inner ring, which has a radius of 9 feet
Total distance traveled by Kelly is circumference of circle with radius 9 feet i.e.
⇒ [tex]Distance = 2\pi r[/tex]
⇒ [tex]Distance = 2(3.14) 9[/tex]
⇒ [tex]Distance = 56.52feet[/tex]
Maya is riding on the outer ring, which is 8 feet farther out from the center than the inner ring .
Total distance traveled by Maya is circumference of circle with radius (8+9=17) feet i.e.
⇒ [tex]Distance = 2\pi r[/tex]
⇒ [tex]Distance = 2(3.14) 17[/tex]
⇒ [tex]Distance = 106.76feet[/tex]
Therefore , Difference in distance is : [tex]106.76-56.52 = 50.24 feet[/tex]
Now , Speed of both is give by
⇒ [tex]Speed_k_e_l_l_y=\frac{56.52}{12} = 4.71 feet/sec[/tex] And ,
⇒ [tex]Speed_M_a_y_a=\frac{106.76}{12} = 8.90 feet/sec[/tex]
Faster Maya travels = 8.90-4.71 = 4.19
So , Maya travels [tex]4.19 feet/sec[/tex] faster than Kelly !

Why should you accurately complete a W-4 form any time you start a new
job or change your tax status? *
You must fill it out accurately so your employer knows how much tax to withhold from your paycheck. The amount withheld is based on your filing status, number of dependents, anticipated tax credits and deductions. If you do not fill it out correctly, you could possibly end up owing taxes when you file your tax return.
Accurately completing a W-4 form when starting a new job or changing tax status is important to ensure the correct amount of federal income tax is withheld from your paycheck.
Explanation:When starting a new job or changing tax status, it is important to accurately complete a W-4 form. This form determines the amount of federal income tax that is withheld from your paycheck. By accurately completing the form, you can ensure that the correct amount of tax is being withheld and avoid underpaying or overpaying your taxes.
Completing the W-4 form involves providing information about your filing status, number of allowances, and any additional amount you want to withhold. The number of allowances you claim on the form affects the amount of tax that is withheld. For example, claiming more allowances means less tax will be withheld from your paycheck, resulting in more take-home pay.
Accurately completing the W-4 form is important because it helps you avoid owing a large amount of tax when you file your tax return and potentially facing penalties for underpayment. It also helps you avoid overpaying and potentially receiving a large tax refund. By reviewing and updating your W-4 form when starting a new job or experiencing a change in tax status, you can ensure that the correct amount of tax is being withheld from your paycheck.

| 57. Macy, Sydney, and Alle are sisters. Macy is liyo
years older than Sydney and Allie is one war
less than half the age of Sydney. If the sum of
their ages is 31, how old is Magy?
Let S be Sydney's age.
Macy = S + Liyo, Alle = (1/2)S - 1.
Given, S + (S + Liyo) + ((1/2)S - 1) = 31.
Substituting Liyo = S and solving gives Sydney = 10, Macy = 15.
So, Macy is 15 years old.
To solve this problem, let's assign variables to represent each sister's age. Let S be Sydney's age. Given that Macy is Liyo years older than Sydney, Macy's age would be S + Liyo. Since Allie is one year less than half the age of Sydney, Allie's age can be represented as (1/2)S - 1.
The sum of their ages is given as 31, so we can set up the equation: S + (S + Liyo) + ((1/2)S - 1) = 31. Substituting Liyo with S, we can solve for Sydney's age (S). Once we find Sydney's age, we can then find Macy's age by adding Liyo to Sydney's age.
By solving the equation, we find that Sydney is 10 years old. Thus, Macy is 15 years old (10 + Liyo). Therefore, Macy is 15 years old.
Complete Question:
Macy, Sydney, and Alle are sisters. Macy is liyo years older than Sydney and Allie is one war less than half the age of Sydney. If the sum of their ages is 31, how old is Magy?

Martin is going to ride in the great bicycle race which is 7/10 as long as the 100- mile astounding race how long is the great bicycle race
Answer: 70 miles long
Step-by-step explanation:
7/10 x 100 = 70
its 70 miles long
Final answer:
The great bicycle race is 70 miles long.
Explanation:
To find the length of the great bicycle race, we need to multiply the length of the 100-mile astounding race by 7/10. Since 7/10 is a fraction, we can represent it as 7 divided by 10. Multiplying by a fraction is the same as multiplying the numerator by the same factor as the denominator. Therefore, we can multiply 100 by 7 and divide by 10 to find the length of the great bicycle race.
There are a few ways to do this computation. One way is to multiply 100 by 7, which equals 700, and then divide 700 by 10. The result is 70 miles. Therefore, the great bicycle race is 70 miles long.

What does the value of x have to be so that
(x,-7) and (-1,4) have a slope of 11/4 between them?
Solution:
The slope of a line is given by formula:
[tex]Slope = \frac{ y_2-y_1}{x_2-x_1}[/tex]
From given,
[tex]slope = \frac{11}4}\\\\(x_1, y_1) = (x, -7)\\\\(x_2, y_2) = (-1, 4)[/tex]
Substituting the values we get,
[tex]\frac{11}{4} = \frac{4+7}{-1-x}\\\\-11 - 11x = 11 \times 4\\\\-11-11x = 44\\\\11x = -11-44\\\\11x = 55\\\\x = 5[/tex]
Thus the value of x is 5
If f(x) = x2 − 6x + 19, complete the square and determine the minimum or maximum value of the function
Answer:
minimum value = 10
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
To obtain this form using completing the square
add/subtract ( half the coefficient of the x- term )² to x² - 6x
f(x) = x² + 2(- 3)x + 9 - 9 + 19
= (x - 3)² + 10 ← in vertex form
with (h, k) = (3, 10 )
To determine maximum or minimum consider the value of a
• If a > 0 then minimum value of k
• If a < 0 then maximum value of k
Here a = 1 > 0, hence minimum value of k = 10
