Answer:
40 carnations
Step-by-step explanation:
Using the principle of proportional relationship, the number of carnations to be used in the bouquet is 40
Setting up the proportional relationship thus :
2 roses = 5 carnations ----(1)
16 roses = P carnations - - - - - 2)
Solve for p :
Cross multiply :
2p = 16 × 5
2p = 80
p = 80 /2
p = 40
Therefore, the Number of carnations to be used is 40

The guttering hold up to 20 litre of rain water. Work out the length of guttering in meters if the diameter is 11.5cm.
Answer:
1107.0213 cm
Step-by-step explanation:
Assuming this gutter is half a cylinder,
Volume of half a cylinder = 0.5(πr²l)²
where, Volume = 20l, π = 3.142, r = 0.5(11.5) and l = ?
But, the other units are in cm while the Volume is in liters, so let's convert the liters to cm³
It would be easier to convert the liters to m³ then to cm³ rather than converting directly. So,
1000 L = 1 m³
1 L = ?
1 ÷ 1000 = 0.001 m³
1 m³ = 1,000,000cm³
0.001 m³ = ?
0.001 x 1,000,000 = 1000 cm³
So, if 1 L = 1000 cm³
20 L = ?
20 x 1000 = 20,000 cm³
Thus, 20,000 = 0.5(3.142 x 0.5(11.5) x l)
20,000 = 0.5(3.142 x 5.75 x l)
20,000 = 18.0665l
Make l the subject and divide both sides by 18.0665
length = 1107.0213 cm

2. During typhoon Ambo, PAGASA tracks the amount of accumulating rainfall. For
<en place.
the first three hours of typhoon, the rain fell at a constant rate of 25mm per hour.
The typhoon slows down for an hour and started again at a constant rate of 20 mm
per hour for the next two hours. Write a piecewise function that models the amount
of rainfall as function of time.
Answer:
The piecewise equation is given as :[tex]A(t)=\begin{cases} 25x& \text{ if } 0 \leq x \leq 3 \\ 75& \text{ if } 3<x<4 \\ 75+20(x-4) & \text{ if } 4 \leq x \leq 6\end{cases}[/tex]
Step-by-step explanation:
Let x be the time in hour and A(x) be the amount of accumulating rainfall at time x.
We are given that in the first three hours the rain fell at a constant rate of 25mm per hour
Amount of rainfall in 1 hour = 25
Amount of rainfall in t hours = 25x
[tex]A(x) = 25x ; 0 \leq x \leq 3[/tex]
The rain then slows down and remains constant
So, Amount of rain for that hour = [tex]25 \times 3 = 75 mm[/tex]
75 mm ; 3
Now we are given that started again at a constant rate of 20 mm per hour for the next two hours.
Amount of rain after 4 hours = [tex]75+20(x-4) ; 4 \leq x\leq 6[/tex]
The rain increases at a rate of 20t from 4 ≤ x ≤ 6.
Hence the piecewise equation is given as :[tex]A(t)=\begin{cases} 25x& \text{ if } 0 \leq x \leq 3 \\ 75& \text{ if } 3<x<4 \\ 75+20(x-4) & \text{ if } 4 \leq x \leq 6\end{cases}[/tex]

Which equation can you use to find the amount of money Sam had in his pocket? How much money did Sam have in his pocket?.
Find: How much money did Sam have in his pocket?.
Solution: Let the equation be
=> P = T +Fp represent amount of money
p represent amount of moneyt represent total
p represent amount of moneyt represent totalf represent money found
=> P = T + Finsert the values
=> P = $19.75 + $6.50add 19.75 from 6.50
=> P = 26.25THEREFORE THE AMOUNT OF MONEY SAM HAVE IN HIS POCKET IS ABOUT $26.25

The sides of a triangle are represented by (3s - 1), (2s + 5), and (s + 4).
1.)Find the expression for the perimeter of the triangle.
2.) What will be the perimeter if s = 7?
Answer:
1) 6s + 8
2) 50
Step-by-step explanation:
1)
To find the perimeter, add the lengths of the sides.
perimeter = 3s - 1 + 2s + 5 + s + 4
perimeter = 6s + 8
2)
Replace s with 7 in the perimeter expression.
perimeter = 6(7) + 8
perimeter = 42 + 8
perimeter = 50
Answer: 6s+8

iready area and circumference of a circle
Answer:
72.22
Step-by-step explanation:
C = [tex]\pi \: d[/tex]
3.14×23=72.22
The circumference of a circle whose radius is 11.5 inches.
Thus, option (a) is correct.
Given:
Diameter = 23 inch
So, Radius of circle = diameter/2
=23/2
= 11.5 inch
Now, the formula for circumference of a circle is
= 2πr
Substituting the value of r= 11.5 into the formula as
= 2 x 3.14 x 11.5
= 72.22 inches
Thus, the circumference of circle is 72.22 inches.

Circle M dilated by a scale factor of 3 gives circle N. If the circumference of circle N is 6 cm, what is the circumference of circle M?
A.
54 cm
B.
3 cm
C.
2 cm
D.
18 cm
Step-by-step explanation:
2 cm
scale factor of 3
then 6/3 = 2 cm
Answer:
C. 2 cm
Step-by-step explanation:
As the circumference is a measure of length (one dimension), we can simply divide the given circumference of circle N by the scale factor to find the circumference of circle M:
⇒ circumference of circle M = circumference of circle N ÷ scale factor
= 6 cm ÷ 3
= 2 cm
(If we were working with area, we would have to divide/multiply by the square of the scale factor, since we would be working in 2 dimensions)

A rectangle has a length of x and a width that is 8 units shorter than twice the length.
a. Draw a picture to represent the box.
b. Write a simplified polynomial to represent the area of the rectangle.
c. What would the area be if = 10 ?
Step-by-step explanation:
length = x
width = 2x-8
b.) to get the area you need to multiply the length and the width.
l×w= area
x(2x-8)
2x^2-8x
c.) 2x^2-8x = 10
subtract 10 both sides
2x^2-8x-10 = 0
2(x^2-4x-5) = 0
2(x-5)(x+1) = 0
x = 5
the area would be 10.

A G.P. Bulk bills at $41.20 per consultation, and sees a new patient every 15 minutes for 3 hours. A new employee calculates the number of patients and then calculates the Medicare bill as follows: Number of patients: 3 ÷ 0.15 = 20 Medicare bill: 20 × $41.20 = $ 824
Given that,
A G.P. Bulk bills at $41.20 per consultation, and sees a new patient every 15 minutes for 3 hours.
Solution,
3 hours means 180 minutes
It means that he sees a new patient every 15 minutes for 180 minutes.
No of patients = [tex]\dfrac{180}{15}=12[/tex]
Fees for per consultation is $41.20. Total bill will be :
