the production increase uniforormuly - What
Increase in production:
is the Annual
9514 1404 393
Answer:
7800 units per year
Step-by-step explanation:
The increase over 5 years is ...
89,000 -50,000 = 39,000 . . . . units
Then the increase per year is ...
(39,000 units)/(5 years) = 7,800 units/year
Angle DEB is 71. What size is ABD
Answer:
71°
Step-by-step explanation:
ABD is alternate to DEB. Therefore ADB = DEB = 71°
The required size of angle ABD is 71.
What is alternate segment theorem?The theorem states that “For any circle, the angle formed between the tangent and the chord through the point of contact of the tangent is equal to the angle formed by the chord in the alternate segment”.
Now it is given that,
angle DEB = 71
Also given that B is the point on the circumference of the circle, and suppose “O” be the centre of the circle.
Now, AC is the tangent of the circle that passes through point B.
The tangent makes an angle ABD with the chord BD.
Now, given that ∠DEB = 71 in the alternate segment.
Now, we have to prove that ∠ABD = 71.
Thus, OD =OB (Both are the radii of the circle)
Also, ∠ODB = ∠OBD (since the angles opposite to the equal sides are equal)
Since, OBD is an isosceles triangle
∠BOD = 180° – ∠ODB – ∠OBD
∠BOD = 180° – 2∠OBD …(1)
Since, the line segment AC is the tangent line,
∠OBA = 90°
Therefore, ∠OBA = 90° – ∠OBD …(2)
From the equations (1) and (2), we can write
∠AOB = 2∠DEB
We know that the angle at the centre of the circle is twice the angle at the circumference of the circle.
∠BOD = 2∠DEB
∠DEB = (½)∠BOD
Now, substitute ∠BOD = 2∠DEB in the above equation, we get
∠DEB = (½)2∠DEB
∠DEB = ∠DEB
⇒ ∠DEB =71
Thus, the required size of angle ABD is 71.

A family discount card offers deals for the cinema. The card states:
The cost of an adult is $10. A child’s ticket is $6.
FAMILY DISCOUNT CARD
- 45% off all adults tickets
- Children save 2/5 off of full price tickets
a) How much will it cost to buy 2 adult tickets and children’s tickets?
b) The cost of a family discount card is $40 per year. How many times in the same year would 2 adults and 3 children need to go before you start to save
money on the cost of the card? 7m
Answer:
a)£21.80
b) 3 trips
Step-by-step explanation:
The cost of an adult is $10.
A child’s ticket is $6.
FAMILY DISCOUNT CARD
- 45% off all adults tickets
- Children save 2/5 off of full price tickets
a) How much will it cost to buy 2 adult tickets and children’s tickets?
(a)
Adults: 2 × £10 = £20
(45 ÷ 100) x £20 = £9
£20 - £9 = £11
Children: 3 × £6 = £18
2 /5 of £18 = £7.20
£18 - £7.20 = £10.80
Total: £11 + £10.80 = £21.80
b) The cost of a family discount card is $40 per year. How many times in the same year would 2 adults and 3 children need to go before you start to savemoney on the cost of the card?
(b) Cost without discount = £20 + £18 = £38b)
No card
1 trip
1 × £38 = £38
2 × £38 = £76
3 × £ 38 = £114
With card
£40 + (1 × £21.80) = £61.80
2 trips 2 × £38 = £76 £40 + (2 × £21.80) = £83.60
3 trips 3 x £38 = £114 £40 + (3 × £21.80) = £105.40
3 trips before the discount card starts being cheaper than regular price

Answer:

2. Circumference
3. Area of the circle is 3850 [tex]cm^{2}[/tex].
ii. Circumference of the circle is 220 cm.
Step-by-step explanation:
The area, A, and the circumference, c, of a circle can be determined respectively by:
A = [tex]\pi[/tex][tex]r^{2}[/tex]
C = 2[tex]\pi[/tex]r
where r is the radius of the circle.
1. the ratio of the circumference and diameter, D, of a circle is:
r = [tex]\frac{D}{2}[/tex]
so that,
C = 2[tex]\pi[/tex][tex]\frac{D}{2}[/tex]
C = [tex]\pi[/tex]D
[tex]\frac{C}{D}[/tex] = [tex]\pi[/tex]
= [tex]\frac{22}{7}[/tex]
= 3.143
2. The distance around a circular region is known as it's circumference.
3. Given a circle of radius 35 cm, then:
A = [tex]\pi[/tex][tex]r^{2}[/tex]
= [tex]\frac{22}{7}[/tex] x [tex](35)^{2}[/tex]
= [tex]\frac{22}{7}[/tex] x 1225
= 22 x 175
A = 3850
Area of the circle is 3850 [tex]cm^{2}[/tex].
C = 2[tex]\pi[/tex]r
= 2 x [tex]\frac{22}{7}[/tex] x 35
= 2 x 22 x 5
= 220
C = 220 cm
Circumference of the circle is 220 cm.

Equation of the line is: [tex]x=6[/tex]
Step-by-step explanation:
We know that , the equation of any line parallel to y axis is :
[tex]x=k[/tex] where [tex]k[/tex] ia a constant
And here it is given that the line is passing through the point P(6,-3)
Therefore, it will satisfy the equation [tex]x=k[/tex].

Gavin collects a certain type of seashell. He has 160 seashells. The seashells' weights are distributed normally, with a mean of 120 grams and a
standard deviation of 26 grams.
How many of the seashells weigh at least 68 grams?
A 134
В.152
C.156
D. 109
Answer: C.156
Step-by-step explanation:
Given: Total seashells = 160
mean = 120
population standard deviation = 26 grams
The probability that the seashells weigh at least 68 grams :-'
[tex]P(X\geq68) =P(\dfrac{x-\mu}{\sigma}\geq\dfrac{68-120}{26})\\\\=P(z\geq-2)\\\\=P(z<2)\ \ \ [P(Z\geq-z)=P(Z<z)]\\\\= 0.9772\ \ \ [\text{By p-value table}][/tex]
Total seashells weigh at least 68 grams = 0.9772 x 160 = 156.352≈ 156
Hence, the correct option is C.156

Cus the other guy is big brain
The scale factor of the dilation of line segment BA is 5.
What is Scale factor?To adjust the size of a figure without altering its shape, a scale factor is a number or conversion factor that is utilised. It is employed to change the size of an object. If the original figure's dimensions and the dilated (increased or lowered) figure's dimensions are known, the scale factor can be determined.
When both the original dimensions and the new dimensions are known, the scale factor may be determined. When employing the scale factor, there are two terms that must be understood. When a figure's size is increased, we refer to this as scaling up, and when its size is decreased, we refer to this as scaling down.
Given:
AC= 4
AA' = 16
and, A'C= 16+ 4 = 20
So, scale factor = AC/ A'C
= 4/5
= 1/5
Hence, the scale factor of the dilation of line segment BA is 5.

A person standing 248 feet from the base of a church observed the angle of elevation to the
church's steeple to be 43. How tall is the church? (Give your answer to the nearest whole number)
How tall is the church?
Answer:
h = 231 feet
Step-by-step explanation:
Given that,
A person standing 248 feet from the base of a church, x = 248 feet
The angle of elevation to the church's steeple to be 43°.
We need to find the tall of the church. Let the length of the church is h. Using trigonometry to find it.
[tex]\tan\theta=\dfrac{P}{B}\\\\\tan\theta=\dfrac{h}{x}\\\\h=x\tan\theta\\\\h=248\times \tan(43)\\\\=231.26\ \text{feet}[/tex]
or
h = 231 feet
So, the height of the church is 231 feet.
