For each 13 mm of coloured fabric Gordon uses to make his curtains he also uses 1 cm of white fabric express the amount of white fabric to coloured fabric as a ratio in its simplest form
Answer:
[tex]\frac{10}{13}[/tex]
Step-by-step explanation:
In the question, the units of the length of both colored and white fabrics are not the same. So, convert the unit of the white fabrics into mm.
The length of colored fabric used = 13 mm.
The length of white fabric used = 1 cm
= 10 mm
To express the white fabric to colored fabric, we have;
[tex]\frac{length of white fabric used}{length of colored fabric used}[/tex] = [tex]\frac{10mm}{13mm}[/tex]
= [tex]\frac{10}{13}[/tex]
Thus, the amount of white fabric to colored fabric can be expressed as[tex]\frac{10}{13}[/tex].

Answer:
22=90 23=15 24=60 25=0.75 26=70 37=$0.58
Step-by-step explanation:
22. So, we can divide 360 kmh by 4 hours
so 360/4 =90
So 90 kmh in 1 hr
23
So, we can divide 3 packages by $15
so 15÷3 = $5
So $5 per package
24 So, we can divide 720 m by 12s
So, 720/12= 60
60 m in 1 s
25
So, we can divide $4.50 by 6
So, we get $0.75
26
So, we can divide 210 words by 3 min
So, 210÷3=70
70 words per minute
27
So, we can divide 23.20 by 40l

15:2 = x : 3 . Find x
Step-by-step explanation:
15/2=x/3
15×3/2=x
45/2=x
22.5=x
Answer:
22.5
Step-by-step explanation:
First find out the ratio x : 1
2 / 2 = 1
15 /2 = 7.5
Now you have this ratio
7.5 : 1
Now times each value by 3 to get the answer :
22.5 : 3
x = 22.5

a/k + b = c/k make k as a subject
Answer:
By "make k as a subject", I assume you mean to solve for k?
If that is the case, then the answer is:
k = (c - a) / b
Step-by-step explanation:
Let's solve for k
a/k + b = c/k
Multiply both sides by k:
a + bk = c
Group terms containing k on the left:
bk = c - a
Divide both sides by k:
k = (c - a) / b

why is the graph of the rose curve r=4cos2theta
Answer:
The correct answer is B.
Step-by-step explanation:
Any point can be represented in polar form by using the notation:
[tex]A = (r, \theta)[/tex] (1)
And any polar function must satisfy the following definition:
[tex]r = f(\theta)[/tex]
Let [tex]r(\theta) = 4\cdot \cos 2\theta[/tex], where [tex]r[/tex] is the radial distance of any point of the curve from origin and [tex]\theta[/tex] is the direction of any point of the curve with respect to +x semiaxis, measured in radians.
Finally, we proceed to graph the function with the help of a graphing tool and attach the result.
Besides, we must remember that cosine is a bounded function, which means that domain and range in rectangular coordinates are represented by:
[tex]Dom\{f\} = [-4,4][/tex], [tex]Ran\{f\} = [-4,4][/tex]
Then, the correct answer is B.
Is the relation a function or no function?
Answer: I think is a function

At a restaurant, the amount of your bill before taxes and tip is $19.83. A 6% sales tax is applied to your bill, and you leave a tip equal to 19% of the original amount. Use mental math to estimate the total amount of money you pay to the nearest dollar.
Answer:
$24.7875
Step-by-step explanation:
Step one:
given data
your bill before taxes and tip is $19.83
6% sales tax
tip equal to 19% of the original amount.
Required
The total expenses
Step two:
let the total expenses be y
let us calculate the cost of tax and the tip
Tax
=6/100*19.83
=0.06*19.83
=$1.1898
Tip
=19/100*19.83
=0.19*19.83
=$3.7677
Total
Y= 19.83 +1.1898 +3.7677
Y= $24.7875
Dylan gets his pictures developed at photo-phast. photo phast uses the equation c=$0.15 • p to calculate the cost, C , of p photographs. Anne gets her pics developed at Quick-pix.

Factor x2 – 8x + 15.
Which pair of numbers has a product of ac and a sum of b?
What is the factored form of the trinomial?
Answer:
x^2-8x+15
X^2+(a+b)X+ac
=X^2-(5+3)X+(1)(15)
a+b=8
ac=15
=x^2-5x-3x+15
=x(x-5)-3(x-5)
=(x-3)(x-5)
Answer:
a) -3 and -5
a) (x - 3) (x - 5)
Step-by-step explanation:
Solve the following system of equations by substitution. Make sure to check your solution. x + y = 5 3x - y = -5
Answer:
(0.5)
Step-by-step explanation:
x + y = 5
3x - y = -5
Put "y" on one side to isolate
3x - y = -5
3x = y - 5
3x + 5 = y
Plug "3x + 5" in for "y" in the second equation
x + (3x + 5) = 5
4x + 5 = 5
4x = 0
x = 0
Plug "0" in for "x" in any one of the equations
0 + y = 5
y = 5
To check, plug in "0" for "x" into the first equation and make sure they get the same answers
3(0) - y = -5
0 - y = -5
y = 5

Which ordered pair is a solution of the equation?
52 - 2y = 18
Answer: y=17
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
52−2y=18
52+−2y=18
−2y+52=18
Step 2: Subtract 52 from both sides.
−2y+52−52=18−52
−2y=−34
Step 3: Divide both sides by -2.
−2y

A perfectly spherical scoop of ice cream has a surface area of 36π cm2 and the same diameter as the open end of the ice cream cone it rests on. The cone is 11 cm tall. If the ice cream melts into the cone, what volume of ice cream will overflow?
Answer:
9.43 cm³
Step-by-step explanation:
Given that the surface area of the spherical scoop is 36π cm², we find its radius. The surface area of a sphere, A = 4πr² where r = radius
36π cm² = 4πr²
r² = 36π cm²/4π
r² = 9 cm²
r = √(9 cm²)
r = 3 cm
So, the volume of the spherical scoop of ice cream is thus V = 4πr³/3
= 4π(3 cm)³/3
= 4π(9 cm³)
= 36π cm³
The volume of the ice cream cone is V' = πr²h/3 where r = radius of cone = radius of spherical scoop = 3cm and h = height of cone = 11 cm
V' = π(3 cm)² × 11 cm/3
= 9π cm² × 11 cm/3
= 33π cm³
So, the volume of ice cream that will overflow is thus V - V' = 36π cm³ - 33π cm³
= 3π cm³
= 9.43 cm³
