Answer:
a) UT² = ST · (RS + ST)
b) UT = 6 in
Step-by-step explanation:
Secant : a line that intersects the circle at two pointsTangent : a line that touches the circle at one pointIf a secant and a tangent of a circle are drawn from a point outside the circle, then the product of the lengths of the secant and its external segment equals the square of the length of the tangent segment.
UT² = ST · (RS + ST)
Given:
RT = 9 inST = 4 inRS + ST = RT⇒ RS + 4 = 9
⇒ RS = 5
Using: UT² = ST · (RS + ST)
⇒ UT² = 4(5 + 4)
⇒ UT² = 36

Answers
Answer:
Explained briefly below.Step-by-step explanation:
For old circular garden:
take the radius as r.
then use the formula to find area of circle: πr² ......this is old garden area.
For new enlarged garden:
the radius is twice the old radius so, radius = 2 * r = 2r ......enlarged radius
now find area for this new garden: π(2r)² → 4πr²
In common fractions: (old garden)/(new garden)
: ( πr² ) / ( 4πr² )
: 1/4
Answer:
1/4Step-by-step explanation:
Original diameter is d and new diameter is D and:
D = 2dArea of original circle:
A₁ = πd²/4Area of enlarged circle:
A₂ = πD²/4 = π(2d)²/4 = πd²The ratio of areas:
A₁ / A₂ =πd²/4 ÷ πd² = 1/4 ÷ 1 = 1/420089 (4 significant figures)

City Park is a right triangle with a base of 40 yd
and a height of 25 yd. On a map, the park has a
base of 40 in. and a height of 25 in. What is the
ratio of the area of the triangle on the map to
the area of City Park?
Answers
Answer:
Let's Convert yards into inches
Base = 40 yards = 1440 inches
Height = 25 yards = 900 inches
Base (Map)/Base (Actual)
40/1440 = 1 : 36
Height (Map)/Height (Actual)
25/900 = 1 : 36
I hope it helps you!
Step-by-step explanation:
Let's expand our knowledge even more by explaining.
The scale of the height and the width is 1 inch equals 1 yard.
the scale of the area would be 1 square inch equals 1 square yard.
for example:
the area of a triangle is equal to 1/2 * base * height.
the base on the map is 40 inches and the height on the map is 25 inches.
the area on the map is therefore 1/2 * 40 * 25 = 500 square inches.
the base in the real world is 40 yards and the height in the real world is 25 yards.
the area in the real world is therefore equal to 1/2 * 40 * 25 = 500 square yards.
the ratio of the area on the map to the area in the real world is 500 square inches / 500 square yards equals 1 square inch / 1 square yard.
that's 1 square inch to 1 square yard.
in general, if the scale in the linear measurements were a/b, then the scale in area would be (a/b)^2.
since your scale in linear measurements is 1/1, then the scale in area would be (1/1)^2 which is equal to 1/1.
assuming the scale in linear measurements were 1/2, then the scale in area would be (1/2)^2 = 1^2/2^2 = 1/4.

Answers
Answer:
Assuming C stands for Circumference we will assume the circum is pi/7
Therefore x = 1/196pi
Step-by-step explanation:
First find the radius with C = 2 * r * pi
1/7pi = 2 * r * pi
r = (1/7pi)/2pi
r = 1/14
Now for the area we have A = r^2 * pi
A = (1/14)^2 * pi

Answer:
$4.00 and $0.40
Step-by-step explanation:
Preferred dividend = $100 x 4% = $4 per share
$4 x 10,000 shares = $40,000
$80,000 paid - $40,000 preferred = $40,000 common dividend
$40,000 / 100,000 common shares = $0.40 per share
The dividends per share for preferred and common stock for the year is: $4.00 and $0.40.
Dividends per share for preferred and common stockDividends per share for preferred = $100 x0.04
Dividends per share for preferred = $4 per share
Common dividend=$80,000 -($4 x 10,000 shares)
Common dividend=$80,000 - $40,000
Common dividend=$40,000
Dividends per share for common stock=$40,000 / 100,000
Dividends per share for common stock = $0.40 per share

solve for w. 5 + 2w = 17
Answers
Answer:
w=6
Step-by-step explanation:
5 + 2w = 17
Subtract 5 from each side
5-5 + 2w = 17-5
2w = 12
Divide each side by 2
2w/2 = 12/2
w = 6
Solution:
Note that:
Given equation: 5 + 2w = 17To solve this problem, isolate the variable by subtracting 5 to both sides of the equation.
=> 5 + 2w = 17=> 5 - 5 + 2w = 17 - 5=> 2w = 12Then, divide 2 both sides to further isolate the variable.
=> 2w = 12=> 2w/2 = 12/2=> w = 6The solution to the equation is 6.

Write 1,386 as the product of its prime factors.
Answers
Answer:
. A prime factor of x is a prime number that divides x correctly (so that the rest is equal to 0). 1386 = 2*3*3*7*11 in our situation. This result can be obtained by dividing the number (1386) by 2, 3, 5, 7, 11, and so on. You utilise the result you get every time you successfully divide it by a prime number (beginning with 2) and try to divide it using the same approach. When you can no longer divide a number by a prime number, you go on to the next prime number and try to divide it by that number. Finally, you multiply the prime numbers by which you were able to divide your number.
Step-by-step explanation:
Answer: We know the prime factorization of a number is the representation of a number in terms of multiples of its factors. Now to simplify the above factorization by applying the exponent rule to make the prime factorization simplest. So, the correct answer is “ $ \ 1386 = 2 \times {3^2} \times 7 \times 11 $ ”.

What is a trapezoid? How do we calculate its area?A trapezoid is a quadrilateral with a necessary pair of parallel lines.
The area of a trapezoid is calculated using the formula,
Area = (1/2)*(sum of parallel sides)*(perpendicular distance between the parallel sides)
What is a line of symmetry?A line of symmetry is the line that divides a figure into equal parts.
How do we solve the given question?The given patio is a quadrilateral. We are shown a line of symmetry. Seeing a single part among the two parts of the figure, we can see that it is a trapezoid with a pair of parallel lines, the shorter one 9ft, and the longer one 20ft. The perpendicular distance between them is 10ft (half of the base of the shown patio).
We calculate the area of this part,
= (1/2)*(9+20)*(10) = 0.5*29*10 = 145 square yards.
The area of the whole patio is twice of this part as both the parts are equal.
∴ Area of the patio = 2*145 = 290 square yards.

What is the equation:
What should the theater charge?
What is the maximum revenue?
Answers
Answer:
r = 12.5p(32 -p)$16 per ticket$3200 maximum revenueStep-by-step explanation:
The number of tickets sold (q) at some price p is apparently ...
q = 150 + 25(20 -p)/2 = 150 +250 -12.5p
q = 12.5(32 -p)
The revenue is the product of the price and the number of tickets sold:
r = pq
r = 12.5p(32 -p) . . . . revenue equation
__
The maximum of revenue will be on the line of symmetry of this quadratic function, which is halfway between the zeros at p=0 and p=32. Revenue will be maximized when ...
p = (0 +32)/2 = 16
The theater should charge $16 per ticket.
__
Maximum revenue will be found by using the above revenue function with p=16.
r = 12.5(16)(32 -16) = $3200 . . . . maximum revenue
_____
Additional comment
The number of tickets sold at $16 will be ...
q = 12.5(32 -16) = 200
It might also be noted that if there are variable costs involved, maximum revenue may not correspond to maximum profit.
