A, B and D are points on the circumference of a circle, centre O.
BOD is a diameter of the circle.
BC and AC are tangents to the circle.
Angle OCB =34.
Work out the size of angle DOA.
Answers
Answer:
Step-by-step explanation:
A tangent makes a 90° angle to the circle.
∠BOC = 180°-90°-34° = 56°
△AOC is congruent to △BOC, so ∠AOC = 56°
∠DOA = 180°-56°-56° = 68°
The size of the angle DOA is 68°
What is the tangent of the circle?"It is the line which intersects the circle exactly at one point."
For given example,
BC and AC are tangents to the circle.
∠OCB = 34°
As, OC is the angle bisector for ∠ACB
⇒ ∠OCB = ∠OCA
⇒ ∠OCA = 34°
⇒ ∠ACB = ∠OCB + ∠OCA
⇒ ∠ACB = 34° + 34°
⇒ ∠ACB = 68°
We know, the tangent to a circle is perpendicular to the radius of the circle.
⇒ CB ⊥ OB
⇒ ∠OBC = 90°
and CA ⊥ OA
⇒ ∠OAC = 90°
We know, the sum of all angles of quadrilateral is 360°.
For quadrilateral ACBO,
⇒ ∠OAC + ∠ACB + ∠OBC + ∠BOA = 360°
⇒ 90° + 68° + 90° + ∠BOA = 360°
⇒ ∠BOA = 112°
We know, the angle subtended by semicircle is 180°.
⇒ ∠AOB + ∠DOA = 180°
⇒ 112° + ∠DOA = 180°
⇒ ∠DOA = 68°
Therefore, the size of the angle DOA is 68°

A point R (-2,5) is mapped to point R',as described by a translation of 6 units to the rights and 7 units down.Mark R' on the coordinate plane.
Answers
Answer:
(4, -2)
Step-by-step explanation:
Given a point R (-2,5), if the point R' is described by a translation of 6 units to the rights and 7 units down, then the coordinate of R' will be;
6 units to the rights is towards the positive x axis
7 units down is towards the negative y axis
R' = (-2+6, 5-7)
R' = (4, -2)
Hence the coordinate point of R' on the plane is (4, -2)

The fabric cost 7cents per square inch. She will only pay for the fabric used to cover the box, even if there is waste or extra. How much money did shyla spend on fabric? Is the box is 7 by 11by 8 inchs
Answers
Answer:
Shyla will pay about 63 cents to cover the box
Step-by-step explanation:
Length of the box ( l ) = 7 inches
Width of the box (b) = 11 inches
Height of the box (h) = 8 inches
We can solve this equation by following two simple steps.
1. The first step is to find the total surface area of the box. This is the total area that the decorative fabric will be covering.
We can get this by the following formula:
SA=2( length X width) +2( length X height )+2(height X width)
SA = 2( 7 X 11 ) + 2(7 X 8) + 2 (8 X 11 ) = 442 square inches
2. The second step is to divide the total surface area by the price of the fabric per square inch.
This will be 442 square inches divided by 7 cents per square inch = 63.14 cents
Shyla will pay about 63 cents to cover the box
A group of 53 tourists visit a museum. Museum volunteers lead tours for groups of no more than 8 tourists. Draw a model to show the least number of groups that can be formed for these 53 tourists. Use circles to show the groups and choose a symbol to show each person.
Answers
Answer:
Total number of group formed = 7
Step-by-step explanation:
As given,
1 group has 8 people
Total people = 53
Let
Total number of group made = x
As 1 group = 8 tourist
⇒x group = 8x tourist
As Total tourist = 53
⇒8x = 53
⇒x = [tex]\frac{53}{8}[/tex] = 6.6
This means,
There are 6 full group of 8 people in each group = 48 tourist
and 1 group of 53-48 = 5 people.
So,
Total number of group formed = 7

Answers
Answer:
X = 2, 4, 6, 7, 9
Y = 29, 33, 37, 39, 43
Step-by-step explanation:
Given a best fit line of :
y = 2x + 25
Take points X as :
X = 2, 4, 6, 7, 9
X = 2
y = 2(2) + 25 = 4 + 25 = 29
X = 4
y = 2(4) + 25 = 8 + 25 = 33
X = 6
y = 2(6) + 25 = 12 + 25 = 37
X = 7
y = 2(7) + 25 = 14 + 25 = 39
X = 9
y = 2(9) + 25 = 18 + 25 = 43

Answers
Answer:

Step-by-step explanation:
It’s convenient that there are only two x values you need to check, -2 and 2. Just insert it to see what y is appropriate.
x = -2: y > 6 + 3 = 9 (and y > -2 + 2 = 0 which is redundant here)
x = 2: y > 2 + 2 = 4 (and y > -6 + 3 = -3 which is redundant here)
So, neither B nor D is in the solution set with 5 < 9 and -5 < 9.
A isn’t in the solution set either with -5 < 4.
C is in the solution set with 5 > 4.

35 of the apartments have a balcony and 55 of them don't. An apartment is randomly selected as part of a survey. What is the probability it has a balcony?
Answers
Answer:
39%
Step-by-step explanation:
It is given that 35 apartments have balconies in them.
While 55 apartments do not have balconies in them.
Total number of balconies is the sum of the apartments. i.e. 35 + 55
= 90 apartments
Therefore for the survey when an apartment is randomly selected, the percentage of the probability of the apartment to have a balcony can be found out by dividing 35 by 90 and then multiply by 100.
i.e.
[tex]$=\frac{35}{90}$[/tex]
= 0.38888888
Multiplying by 100, we get
= 0.388888 x 100
= 38.8888 %
= 39 %
