The length of arc of the given circle, to the nearest hundreth, is: 2.41 units.
What is the Length of an Arc?Length of arc = ∅/360 × 2πr, where the radius of the circle is r, and the reference angle is ∅.
We are given the following:
Radius (r) = 3 units
Reference angle (∅) = 46°
Plug in the values into the length of arc formula:
Length of arc = 46/360 × 2π(3)
Length of arc = 2.41 units.
Therefore, the length of arc of the given circle, to the nearest hundreth, is: 2.41 units.

Sally and Will are very picky eaters. At the start of dinner, Sally pushed half of her peas onto Will's plate. Then, when their mom wasn't looking, Will pushed half of his peas onto Sally's plate. Finally, Sally once again pushed half of her peas onto Will's plate. When their mom said they would get no dessert if they didn't eat their vegetables, Sally had 25 peas on her plate and Will had 47 peas on his plate. How many peas did Sally have at first?
Considering the total of peas is 72, Sally's initial number of peas was 56.
What is the total of peas?Assuming the two brothers did not eat any peas, the total of peas both at the beginning and end is 72 peas.
25 + 47 = 72 peasBy the end, Sally has 25 peas and Will has 72 peas.
How many peas did Sally have before?Before the mother declared none of them would have dessert Sally had given Will half of her peas. This means 25 peas represent half of the peas:
25 x 2 = 50 peas 22 peas in Will's plate
Before this, Will had given Sally half of his peas
22 peas x 2 = 44 peas 28 peas on Sally's plate
Right before this, Sally gave Will half of her peas:
28 x2 = 56 peas 16 peas on Will's plate
Let's check this answer:
S= 56 W= 16 -Beginning
S= 28 W=44 - Sally gives Will half of her peas
S= 50 W=22 - Will gives sally half of his peas
S=25 W= 47 -Sally gives will half of her peas

4. Is (x + 2)a factor of (x + 5x 3 2 - 4x – 20)? -
Answer:
yes
Step-by-step explanation:
if (x + 2) is a factor of the polynomial , then if x = - 2 gives the polynomial a value of zero it is a factor
(- 2)³ + 5(- 2)² - 4(- 2) - 20
= - 8 + 5(4) + 8 - 20
= - 8 + 20 + 8 - 20
= 0
since polynomial = 0 then (x + 2) is a factor

Answer:
CD = 16
Step-by-step explanation:
Segments EF and EC are tangent and secant respectively to the circle drawn from external point E.
Thus, by tangent-secant theorem:
[tex]ED\times EC= EF^2[/tex]
[tex]\implies x(x+x+7)= (15)^2[/tex]
[tex]\implies 2x^2+7x= 225[/tex]
[tex]\implies 2x^2+7x-225=0[/tex]
Comparing above quadratic equation with [tex]ax^2+bx+c=0[/tex], we find:
a = 2, b = 7, c = -225
Now, we find the value of the discriminant
[tex]\implies b^2-4ac= (7)^2-4(2)(-225)= 1849[/tex]
Now, by quadratic formula:
[tex]x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]
[tex]\implies x=\frac{-7\pm\sqrt{1849}}{2(2)}[/tex]
[tex]\implies x=\frac{-7\pm (43)}{4}[/tex]
[tex]\implies x=\frac{-7+ 43}{4}\: or\:x=\frac{-7- 43}{4} [/tex]
[tex]\implies x=\frac{36}{4}\: or\:x=\frac{- 50}{4} [/tex]
[tex]\implies x=9\: or\:x=-12.5 [/tex]
x represents length, so it can't be negative.
[tex]\implies x\neq -12.5[/tex]
[tex]\implies x=9[/tex]

The nutrition supervisor for a school district is considering adding a baked potato bar to the lunch for all the high school cafeterias. He wants to determine if there is a difference in the proportion of students who would purchase from the potato bar for two high schools, East and West. The cafeteria manager at each high school randomly surveys 90 students. At East High School, 63 of the students said they would purchase the potato bar on that day.
At West High School, 45 students said they would. Based on the 99% confidence interval, (0.02, 0.38), is there convincing evidence of a difference in the proportions of students who would purchase from the potato bar between East and West High Schools?
O There is convincing evidence because the entire interval is above 0.
O There is convincing evidence because the sample proportions are different at each high school.
O There is not convincing evidence because another interval using a lower level of confidence might contain 0.
O There is not convincing evidence because the entire student body should have been asked.
Using the confidence interval, it is found that the correct option is:
There is convincing evidence because the entire interval is above 0.
When does a confidence interval for the difference of proportions gives convincing evidence that there is a difference?It gives convincing evidence when 0 is not part of the confidence interval.
In this problem, the interval is (0.02, 0.38), which does not contain 0, hence the correct option is:

To find the area of the circle, first find its radius.
Formulas needed
Circumference of circle= πD= 2πrArea of circle= πr²Given: circumference= 13π cm
2πr= 13π
Divide both sides by 2π:

Answer:
$102
Step-by-step explanation:
The pay for the day of work is the total of morning hours worked and afternoon hours worked. In each case, the hours worked is the difference between the "Out" time and the "In" time.
morning hours = 12:15 -8:15 = 4:00
afternoon hours = 17:30 -13:00 = 4:30
total hours worked = morning hours + afternoon hours
total hours worked = 4:00 +4:30 = 8:30
This notation tells you (hours):(minutes). You know that 30 minutes is 1/2 hour, so the total time worked is 8 1/2 hours.
The pay is the product of the hours worked and the pay per hour:
pay = (8 1/2 hours) × ($12 /hour) = $102
A rectangular box with a square base and no top is to have a volume of 108
The value in cubic yards is 3.996yd³.
What is the volume of the rectangular box?The volume of a rectangular box can be calculated if you know its three dimensions: width, length, and height.
A rectangular box with a square base and no top is to have a volume of 108ft³.
We are to convert the dimension to cubic yards. Using the conversion factor
1 ft³ = 0.0370yd³
108ft³ = x
Cross multiply
1 × x = 108 × 0.0370
x = 3.996
Hence, the value in cubic yards is 3.996yd³.

An arithmetic sequence has this recursive formula:

n = an=1
- 4
What is the explicit formula for this sequence?
An arithmetic sequence can be expressed as explicitly or recursively
The explicit formula of the sequence is [tex]a_n = 11 - 4n[/tex]
How to determine the explicit formulaThe recursive formula is given as:
[tex]a_n = a_{n -1} - 4[/tex]
[tex]a_1 = 7[/tex]
Substitute 2 for n in [tex]a_n = a_{n -1} - 4[/tex]
[tex]a_2 =a_1 - 4[/tex]
This gives
[tex]a_2 =7 - 4[/tex]
[tex]a_2 =3[/tex]
Calculate the common difference (d)
[tex]d = a_2 -a_1[/tex]
[tex]d = 3- 7[/tex]
[tex]d = -4[/tex]
The explicit formula is then calculated as:
[tex]a_n = a_1 + (n - 1)d[/tex]
This gives
[tex]a_n = 7+ (n - 1)*-4[/tex]
Expand
[tex]a_n = 7+4 - 4n[/tex]
[tex]a_n = 11 - 4n[/tex]

Answer:
= 14x +8
Step-by-step explanation:
For the equation in one variable to have infinitely many solutions, it must be true for all values of x. That is, the left side and the right side must simplify to identical expressions.
The left side simplifies to ...
12x -x +8 +3x = (12 -1 +3)x +8 = 14x +8
So, we can give the equation infinitely many solutions if the right side is 14x +8:
12x -x +8 +3x = 14x +8 . . . . has infinitely many solutions
