Step-by-step explanation:
Total of octagon amount is 1080, so set it equal.
x + 2x + 3x + 4x + 6x + 7x + 8x + 9x = 1080
45x = 1080
/45 /45
x = 24
Then plug in for largest number.
9 (24) = 216
A circular garden is enlarged so that the new diameter is twice the old diameter. What is the ratio of the original area to the enlarged area? Express your answer as a common fraction.
I do not understand WHY the answer is 1/4 I do not understand why it is k^2 and all that. HELP I am giving LOTS of points
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 = 1/4Another real estate agent sold a house for $315,000 last week. If her commission is 1.25% of the selling price of the home, find the amount of her commission
Answer:
$3937.50

315,000 * 1.25% = 315,000 * 1.25/100 = 3,150*1.25 = 3937.5
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?
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.

Answer:
Step-by-step explanation:
a + 2 + a+2 + a + 2 = 24 Combine the left
3a + 6 = 24 Subtract 6 from both sides.
3a = 24 - 6 Combine
3a = 18 Divide both sides by 3
3a/3 = 18/3
a = 6
Answer:
1.
3a + 6 OR 3(a + 2)
2.
a = 6
Step-by-step explanation:
1.
(a + 2) + (a + 2) + (a + 2) = a + a + a + 2 + 2 + 2
= 3a + 6 or 3(a + 2)
2.
24 = 3a + 6
24 - 6 = 3a
18 = 3a
18/3 = 6

A cylindrical pillers has a diameter of 56 cm and is of 35 m high there are 16 pillers around the building find the cost of painting the curved surface area of all the pillars at the rate of 5.50 per 1m square
Answer:
Answer:
Total cuŕved surface area of the pillars = 985.6m²Total cost of painting = Rs.5420.8
Explanation:
Given,
A cylindrical pillar with dimènsions,
r(radius) = 56/2 = 28cm. [ Since d = r/2]h(height) = 35m
There are 16 such pillars. Find the cost of paiñting the the curved surface area of all pillars 5.50/m²
Conversion of the dimensioñs in same units.
Radius = 28cm
= 28 ÷ 100 [Since 1m = 100]
= 0.28m
Cuŕved surface area of the pillar is given by,
→ 2πrh
Where,
Taking ‘π’ as 22/7
→ 2*(22/7)*(0.28)*(35)

Saville Company has 10,000 shares of $100 par, 4% cumulative preferred stock and 100,000 shares of
$10 par common stock. All past dividends for preferred shareholders have been paid. Dividends
totaling $80,000 have been declared.
Determine the dividends per share for preferred and common stock for the year.
Question 10 options:
$4.00 and $4.00
$4.00 and $0.40
$2.00 and $0.40
$2.00 and $4.00
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
Inconclusion the dividends per share for preferred and common stock for the year is: $4.00 and $0.40.

Write 1,386 as the product of its prime factors.
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 $ ”.

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 = RTUsing: UT² = ST · (RS + ST)
⇒ UT² = 4(5 + 4)
⇒ UT² = 36
⇒ UT = √36 = 6 in
Richard wants to install a paver patio in the shape shown. The dotted line represents a line of symmetry. How many square yards of pavers does Richard need to cover the entire patio?
1. 400
2. 290
3. 190
4. 180
Answer:
number 2: 290
Step-by-step explanation:
triangle: 11 x 20 = 220 ÷ 2 = 110
rectangle: 9 x 20 = 180
180 + 110 = 290
Richard will need 290 square yards of pavers to cover the entire patio.
∴ Option 2. 290 is the right option.
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.

Find the area of the circle. Give your answer in terms of x. C= pie over 7
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
A = 1/196 * pi
