For each 48 mm of coloured fabric Fiona uses to make her curtains, she also
uses 1.2 cm of white fabric. Express the amount of white fabric to coloured
fabric as a ratio in its simplest form.
Answer: [tex]\frac{1}{4}[/tex]
Step-by-step explanation:
1.2 cm = 12 mm
So the amount of white fabric to coloured fabric is:
[tex]\frac{12}{48}[/tex] = [tex]\frac{1}{4}[/tex]
Write the equation of the line that passes through the points (-1,-5) and (2,4).
Answer:
y=3x+1
Step-by-step explanation:
First, we have to find the slope. [tex]\frac{4-(-5)}{2-(-1)}[/tex] This comes out to 9/3. This becomes 3. Now we need to find the y-intercept. Now write out how to find the answer. 4=3(2)+b. 4=3+b. Subtract 3 from both sides to get 1=b. Now write out the equation. y=3x+1

Which function has a greater slope and y-intercept than the linear function represented in the table?
A) y=2x+8.5
B) y=3x+7.5
C) y=5x+6.5
D) y=10x+5.5
Answer:
B) y=3x+7.5
Step-by-step explanation:
The equation of the data in the table can be obtained by using any two points.
We will use points (3, 13) and (5,17)
The slope - intercept form is:
y = mx + bWe find the slope as:
m = (17-13)/(5-3) = 4/2 = 2The equation becomes:
y = 2x + bTo find the value of b, the y -intercept is:
13 = 2*3 + b ⇒ b= 13 - 6 = 7So the equation is:
y = 2x + 7Now let's compare this with the optionsA) y = 2x + 8.5
The slope is 2, and y- intercept is 8.5It has same slope and greater y-interceptAnswer is noB) y=3x+7.5
The slope is 3, and y- intercept is 7.5It has greater slope and greater y-interceptAnswer is yesC) y=5x+6.5
The slope is 5, and y- intercept is 7.5It has greater slope but smaller y-interceptAnswer is noD) y=10x+5.5
The slope is 10, and y- intercept is 5.5It has greater slope but smaller y-interceptAnswer is noAndre and his dad have been fishing for 2 hours. In that time, they have caught 9 blue gills and 1 yellow perch. How many total fish are there?

Andre and his dad have been fishing for 2 hours. In that time, they have caught 9 blue gills and 1 yellow perch. How many total fish are there?
There are 10 total fish. We are looking at how many fish there are, so we need to add 9 + 1 to get our answer of 10 fish.
The next time Andre gets a bite, what kind of fish do you think it would be?
My prediction is that it will be a blue gill.
How do you know your prediction is more likely to happen?
9 out of 10 times, they have caught a blue gill. This is more probable than 1 out of 10.
Can you make any other predictions?
I would say that Andre will catch less yellow perches than blue gills. This is because the probability of catching a blue gill is greater than catching a yellow perch. I would also say that Andre will catch 5 fish per hour, since he caught 10 fish in 2 hours.

Step-by-step explanation:
A circle is shown. Secants E C and A C intersect at point C outside of the circle. Secant E C intersects the circle at point D. Secant A C intersects the circle at point B. The length of E D is 14, the length of D C is x + 1, the length of A B is 21, and the length of B C is x. What is the value of x? x = 2 x = 3 x = 4 x = 6
Answer:
x = 3
Step-by-step explanation:
Data
DE = 14 unitsCD = x + 1 unitsBA = 21 unitsCB = x unitsTherefore:
CE = CD + DE = x + 1 + 14 = x + 15 unitsCA = CB + BA = x + 21 unitsFrom Intersecting Secants Theorem :
CD*CE = CB*CA
Replacing with data:
(x + 1)*(x + 15) = x*(x + 21)
x² + 15x + x + 15 = x² + 21x
x² + 15x + x + 15 -x² - 21x = 0
15 - 5x = 0
15 = 5x
15/5 = x
3 = x
Answer:
B. x=3

Find the geometric mean of the pair of numbers
Answer: a. 55
Step-by-step explanation:
The formula to find the geometeric mean between two numbers a and b is given by :-
[tex]G.M. =\sqrt{ab}[/tex]
The given numbers are : 275 and 11
The geometric mean of 275 and 11 is given by :-
[tex]G.M.=\sqrt{275\times11}\\\\\Rightarrow\ G.M. =\sqrt{3025}\\\\\Rightarrow\ G.M.=\sqrt{55\times55}\\\\\Rightarrow\ G.M.=\sqrt{55^2}\\\\\Rightarrow\ G.M.=55[/tex]
Hence, the geometric mean of 275 and 11 is 55.
So , the correct option is a. 55 .

At which values of x does the function F(x) have a vertical asymptote? Check
all that apply,
F(x)
9
(x - 1)(x-8)
Answer:
The values of x that makes f(x) have a valid asymptote are 1 and 8
Step-by-step explanation:
Given
[tex]f(x) = \frac{9}{(x-1)(x-8)}[/tex]
Required
At what value does f(x) has a vertical asymptote
To solve this, we simply equate the denominator of f(x) to 0;
This is done as follows
[tex]{(x-1)(x-8)} = 0[/tex]
This can be split to
[tex]{(x-1) = 0 \ or\ (x-8)} = 0[/tex]
Remove brackets
[tex]x-1 = 0 \ or\ x-8 = 0[/tex]
Make x the subject of formula in both cases
[tex]x-1+1 = 0+1 \ or\ x-8+8 = 0+8[/tex]
[tex]x= 0+1 \ or\ x = 0+8[/tex]
[tex]x= 1 \ or\ x = 8[/tex]
The values of x that makes f(x) have a valid asymptote are 1 and 8
Answer:
The correct answer is 1 and 8

Step-by-step explanation:
Once again, these two traingles share angle A and both have right angles. This shows AA similarity.
Now knowing this, we can set up a ratio:
(x+3)/3 = 11/2
Mulptiply both sides by 6:
2x+6 = 33
Isolate x:
2x = 27
divide by 2:
x = 13.5
Answer:
x=13.5
Step-by-step explanation:
i similar triangles sides are proportional.
[tex]\frac{x+3}{3} =\frac{11}{2} \\2x+6=33\\2x=33-6\\2x=27\\x=27/2=13.5[/tex]

Parking for 4 hours costs $10. Parking for 5 hours costs $12. Is this a proportional relationship, and if so, what is the constant of proportionality?
Answer:
Not a Proportional Relationship ; No Constant of Proportionality
Step-by-step explanation:
Consider the first example, 4 hours of parking costs $ 10. From this we can derive the ratio 4 : 10, so that hours parked : fee for parking is a common ratio among the two examples, the other being 5 : 12;
[tex]4 : 10, Simplify\\2 : 5, Take As Fraction,\\Solution; 2 / 5ths\\[/tex]
[tex]5 : 12, Simplify\\( Can't Be Simplified Further ) - Take as Fraction,\\Solution; 5 / 12ths[/tex]
Considering that the fractions when compared are not similar, ( 2 / 5, and 5 / 12 ) they don't have a proportional relationship, and thus have no constant of proportionality
Solution; Not a Proportional Relationship
what’s the answer to this?
Answer:
254.5
Step-by-step explanation:
The area of the figure is the sum of the areas of the parallelogram and the semicircle. (Both the problem statement and the figure tell you this.)
The area of the parallelogram is given by the formula ...
A = bh
where the base is 22 and the height is 9.
A = (22)(9) = 198
__
The area of the semicircle is 1/2 the area of a circle with the same dimensions. The area of a circle is given by the formula ...
A = πr²
where r is the radius, half the diameter. For a radius of 6, the area of a circle would be ...
A = π(6²) = 36π
The area of the semicircle is then ...
36π/2 = 18π ≈ 56.5
__
The area of the irregular shape is the sum of these:
parallelogram area + semicircle area
= 198 +56.4 = 254.5 . . . . square units
Decide whether each point is a solution to the system y 3x+4 and y <3x-2
Answer: No solution at any point
Step-by-step explanation:
If a system of equations comprises of:
y > 3x + 4 and y < 3x - 2
Since they both have the same slope and the different intercept in which one is positive and the other is negative, where first equation is greater than and the second is less than, there will be no solution at any point in the system of the equation because the two equation will create boundaries

Step-by-step explanation:
Carson is a salesman at an insurance company. He receives a monthly salary of $1,478.00 and a $249.00 commission on each policy he sells. If Carson receives his commission check at the end of the month along with his salary check, which of the following equations can be used to determine his total pay for the month.
(Let x represent the number of policies sold and y represent the total amount of pay for the month.
Answer:
A salary with commission involves an employee have a fixed slary base but also receive commission for sales or performance.
Equation: y = 1,478.00 + (249.00)(x)
Step-by-step explanation:
Step 1:
You will multiply the $249 commission rate and the number of each policy he sells. (249)(x)
Step 2:
You then add the monthly salary of 1,478.00 and the answer from step one.
1,4789 + (answer from step 1)
Step 3:
The sum of step 2 is Carson's total pay for the month.
