Answer:
23.7°
9.1~ft
Step-by-step explanation:
Formula for the area of a sector of central angle n (in degrees) and radius r:
[tex] A = \dfrac{n}{360^\circ}\pi r^2 [/tex]
We have:
A = 100 ft^2
r = 22 ft
We need to find:
r
[tex] 100 = \dfrac{n}{360^\circ}\pi (22^2) [/tex]
[tex] n = 23.7^\circ [/tex]
The central angle measures 23.7°.
Formula for the length of an arcs of a circle with central angle n (in degrees) and radius r:
[tex] s = \dfrac{n}{360^\circ}2 \pi r [/tex]
We have:
n = 23.7°
r = 22 ft
We need to find:
s
[tex] s = \dfrac{74.4}{360}2 \pi (22 ft) [/tex]
[tex] s = 9.1~ft [/tex]

Answer: The birthday boy got [tex]\dfrac13[/tex] of cake and rest each of the 4 children got [tex]\dfrac16[/tex] of cake.
Step-by-step explanation:
1 cake is divided into 6 pieces.
1 piece = [tex]\dfrac16[/tex]
Birthday boy got 2 pieces.
Part of cake he has = [tex]2\times\dfrac16=\dfrac26=\dfrac13[/tex] [divide numerator and denominator by 2]

CAN SOMEONE HELP ME PLS AAAAA? Jason purchased a cell phone on sale for $100. He will pay a $25 monthly service for the line. Write an equation for this scenario. Is this a proportional relationship?
Answers
Answer:
Step-by-step explanation:
y = 25x +100
y- is the total money spent on the phone
x-is the number of months you had service
the relationship between x and y is proportional ( if x grows, y grows)
For example: after 2 months you would had payed $100 for the phone + the $25 each of the 2 months. y= 25*2 +100 = $150

the vertex of y=(x-4)(x+2)
Answers
Answer:
(1,-9)
Step-by-step explanation:
Answer:
vertex = (1, - 9 )
Step-by-step explanation:
The vertex is located on the axis of symmetry
The axis of symmetry is at the midpoint of the zeros
Find the zeros by letting y = 0, that is
(x - 4)(x + 2) = 0
Equate each factor to zero and solve for x
x + 2 = 0 ⇒ x = - 2
x - 4 = 0 ⇒ x = 4
Then equation of axis of symmetry/ x- coordinate of vertex is
x = [tex]\frac{-2+4}{2}[/tex] = [tex]\frac{2}{2}[/tex] = 1
Substitute x = 1 into the equation for corresponding value of y
y = (1 - 4)(1 + 2) = (- 3)(3) = - 9
vertex = (1. - 9 )

Answers
Answer: The answers are:
6 + 2 = 8
4 + (-1) = 3
Step-by-step explanation:
Add 6 by 2.
Solve for X.
4 + X = 3
To find X, we use the integer rule. We can use this:
Positive and Positive = Positive
Negative and Negative = Negative
Positive and Negative = Both (It depends if the negative or positive is larger than the other)
For this problem, we can use: Positive and Negative = Both.
If we look at the chart, we can see 4 and 3. How can we get 4 + ? = 3? We can use the integer, -1. Since we said, Positive and Negative = Both, we must compare the positive-addend (4) by the negative-addend (-1).
4 is greater than -1
4 > -1
Therefore, X equals -1.
4 + (-1) = 3
Answer: 8, -1
Step-by-step explanation:
The table shows some addition problems. Each column is its own problem, with the first two rows being addends and the bottom row being the sum. Thus, simply do 6+2 to get the first blank(left-to-right), 8. Then, do 4+x=3 to get the second blank, or -1.

Jo owns a gas station in Ponder, Texas. Last year, Jo sold 5,000 gallons of
gasoline at a price of $1 a gallon. Jo's average cost of producing the
5,000-gallons of gasoline was 50 cents a gallon. Did Jo earn a profit? If so,
how much?
Answers
Answer:
Jo earned a profit of $2500.
Step-by-step explanation:
Given that:
Selling price of 5000 gallons = $1 per gallon
Total selling price = 1 * 5000 = $5000
Production cost = 50 cents per gallon = $0.5 per gallon
Total production cost = 0.5 * 5000 = $2500
Production cost < Selling cost
Therefore,
Jo earned profit on gasoline.
Profit = Selling cost - Production cost
Profit = 5000 - 2500
Profit = $2500
Hence,
Jo earned a profit of $2500.

Answer:
a) 3, 8, 63, 3968
b) some other kind
c) continue to evaluate terms sequentially
Step-by-step explanation:
a) To find the first four terms, use the recurrence relation:
t(1) = 3 . . . given
t(2) = t(1)^2 - 1 = 3^2 -1 = 9 -1 = 8
t(3) = 8^2 -1 = 64 -1 = 63
t(4) = 63^2 -1 = 3969 -1 = 3968
The first 4 terms are 3, 8, 63, 3968.
__
b) The terms have no common difference or ratio, so the sequence is some other kind of sequence. The ratios of terms form a sequence that is approximately exponential.
__
c) Colin can find the 10th term by evaluating successive terms using the recursion relation. (It is approximately 2.0351×10^230.)

Point A is located at –24 and point C is located at 36 on the number line below.
Which value would represent point B, halfway between point A and point C?
Answers
Answer:
Please check the explanation.
Step-by-step explanation:
A number line is a horizontal line with negative values on the left-hand side of an arbitrary number 0 and positive values on the right-hand side of 0.
The location of point A on a number line = -24
The location of point C on a number line = 36
The distance between -24 and 36 can be simply calculated by counting the number of units between.
Starting from -24, we would need to move 24 units on the right side to reach the 0 and 36 units right to reach 36.
So, the total units will be: 24+36 = 60
A second simple method to calculate the distance between point A and point C is:
Distance between A and C = location of C - location of A
= 36 - (-24)
= 36+24
= 60 units
Thus, the distance between A and C is 60 units.
Now, point B is located halfway between point A and point C.
Thus,
The point B must be 30 units before (30 units on the left side) of the point C. In other words, point B must be 30 units after (30 units on the right side) of point A.i.e.
The location of point B = The location of point C - 30
= 36 - 30
= 6
Thus, point B is located at 6.
Verification:
The location of point B = The location of point A + 30
= -24 + 30
= 6
Thus, point B is located at 6.
Thus, it is verified that point B, halfway between point A and point C.
Hence,
'6' is the value of point B halfway between point A and point C.

C. 0
D. 4
Answers
Answer:
A) - 7
slope -intercept form y = - 3x - 7
slope m =-3 and y - intercept c = -7
Step-by-step explanation:
Explanation:-
Given that slope 'm' = -3 and point (0,-7)
The equation of the straight line passing through the point and having slope 'm'
y - y₁ = m ( x- x₁)
The equation of the straight line passing through the point ( 0,-7) and slope m = -3
y - (-7) = -3 ( x -0)
y +7 = -3x
3x +y + 7=0
The equation of the line 3x +y + 7=0
Final answer:-
slope -intercept form y = - 3x - 7
slope m =-3 and y - intercept c = -7
