x = 40
Step-by-step explanation:
Hello there!
Remember the circumference of a circle in degrees is equal to 360
so all of the arcs added together will equal 360
360 = x + 20 + 3x + 15 + 4x + 5
step 1 combine like terms
1x+3x+4x=8x
20+15+5=40
now we have 360 = 8x + 40
step 2 subtract 40 from each side
360 - 40 = 320
40 - 40 cancels out
now we have 320 = 8x
step 3 divide each side by 8
320/8=40
8x/8=x
we're left with x = 40

1. Leslie visits a local department store in order to purchase summer clothes. The
price of the dress is $40. The dress is marked up 25%. What is the selling price of
the dress?
Answers
Answer:
$50
Step-by-step explanation:
Given data
We are given that the price is $40
the markup percent is 25%
Hence the price will be
40+25% of 40
=40+ 25/100*40
=40+ 0.25*40
=40+10
=$50
Therefore, the price of the dress is $50

Answers
Answer:
A = (b1 + b2)h/2
Step-by-step explanation:
The shape given is a trapezoid having two parallel sides which can be labelled b1 and b2 respectively. The distance between the two parallel sides is the height of the trapezoid, which is labelled h.
Area of a trapezoid is given as:

Find the curcumince of the circle. use 3.14 or 22/7.
Answers
Answer:
the circumference of this circle is approximately 25.12 cm with π as 3.14.
Step-by-step explanation:
circumference of a circle is technically a perimeter of a circle.
we find the circumference of a circle by using the following formula :
c = 2πr or c = πd
r represents the radius d represents the diameter
since 4 yds here is a radius, we use the left formula i placed above. then, we substitute the numbers in. pi represents 3.14 as said in your question. even if you use 22/7, you will still get around the same result.
c = 2πr
c = 2(3.14)4
c = 6.28(4)
c = 25.12 yds
therefore, the circumference of this circle is approximately 25.12 yds.
Where is the midpoint of AB if A(6, 4) and B(5,-2)?
A) (11,2)
B (11,6)
C) (5.5,3)
D (5.5,1)
Answers
Answer:
Step-by-step explanation:
The midpoint is just the average coordinates of the endpoints.
mp=((x1+x2)/2, (y1+y2)/2), we have points (6,4) and (5,-2)
mp=((6+5)/2, (4-2)/2)
mp=(5.5, 1)
So D is the answer.

Answer:
∠H = 50°∠A = 80°∠W = 130°Step-by-step explanation:
It is helpful to remember that opposite angles of an inscribed quadrilateral are supplementary. This lets you find the value of m.
∠A +∠K = 180°
8m° +10m° = 180°
18m = 180
m = 180/18 = 10
Using this value we can find ...
∠H = 5m° = 5·10° = 50°
∠A = 8m° = 8·10° = 80°
∠W = 180° -∠H = 180° -50° = 130°

Step-by-step explanation:
(a) The length and breadth of the playground as measured by the surveyor are 20 m and 13 m respectively to nearest metre.
Since the actual length is x m and breadth is y m, then;
i. x ≥ 20 m or x ≤ 20 m
ii. y ≥ 13 m or y ≤ 13 m
(b) perimeter of the playground = 2 (length + breadth)
= 2 ( 20 + 13)
= 2 x 33
= 66 m
The range of values of the perimeter = 65.4 m < perimeter < 66.5 m
ii. area of the playground = length x breadth
= 20 x 13
= 260 [tex]m^{2}[/tex]
The range of values of the area = 259.4 [tex]m^{2}[/tex] < Area < 260.5 [tex]m^{2}[/tex]

A piece of rural land sold ten years ago for 40000. The price for the same land this year is $800 more per acre, and it sold for 60000. What is the size of the piece of land in acres?
Answers
Answer: 25
Step-by-step explanation:
From the question, we are informed that the piece of rural land sold ten years ago for 40000 and that the price for the same land this year is $800 more per acre, and it sold for 60000.
The size of the piece of land in acres will then be:
40000 + 800x = 60000
800x = 60000 - 40000
800x = 20000
x = 20000/800
x = 25
The land is 25 acres
Answer: 25
Step-by-step explanation:
40000 + 800x = 60000800x = 60000 - 40000800x = 20000x = 20000/800x = 25

Answer:
CD = 103°
Step-by-step explanation:
The secant- tangent angle BAD is half the difference of the intercepted arcs, that is
[tex]\frac{1}{2}[/tex] ( CD - BD ) = 29° ( multiply both sides by 2 )
CD - BD = 58°
CD - 45° = 58° ( add 45° to both sides )
