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]

Find the value of x for the triangle below.
Answer:
x = 10
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
sin theta = opposite/ hypotenuse
sin 30 = 5/x
Multiply each side by x
x sin 30 = 5
Divide by sin 30
x = 5/sin 30
x = 10
Answer:
Step-by-step explanation:
in the given triangle . one angle is 90 degree and other angle = 30
therefore third angle = 180 - 120 ( angle sum property of a triangle)
third angle = 60 degree
sin 30 = 5 / x (1)
cos 30 =third side /x (2)
from 1 * 2 we get ,
SIN 30 * COS 30 = 5/X * THIRD SIDE / X
1/2 *[tex]\sqrt{3}[/tex]/2 = 5 * THIRD SIDE / X^2
[tex]\sqrt{3}[/tex] * X^2/10 = THIRD SIDE
BY APPLYING PYTHAGORUS THEOREM
X^2 = 5^2 + [ [tex]\sqrt{3}[/tex] * X^2/10]^2
X^2 = 25 + 3x^4/100
x = square root of 25 + 3x^4/100 = 5+[tex]\sqrt{3}[/tex]x^2/10
x= 5+ [tex]\sqrt{3}[/tex] * x^2/10
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.
Expand and simplify a(t+4)-a(4-3t
Answer:
4at
Step-by-step explanation:
1. Distribute. You well get at+4a-4a+3at.
2. Eliminate the opposites (+4a and -4a cancel out to equal 0, which can then be excluded from the equation). You will get at+3at.
3. Add. at+3at=4at
Answer:
Step-by-step explanation:
Use distributive property
a(t+4) - a(4 - 3t) = a*t + a*4 +(- a) * 4 - (-a)*3t
= at+ 4a - 4a + 3at {combine like terms}
= at + 3at + 4a - 4a {add /subtract like terms}
= 4at

Write 5 as a ratio of two integers
The number 5 is a rational number, so you must be able to express it as a quotient, and you can. Dividing any number by 1 gives you the original number, so to express an integer like 5 as a quotient, you simply write 5/1. The same is true for negative numbers: -5 = -5/1
-5 = -5/1
Step-by-step explanation: I believe it’s this I had it right on my question.

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

Classify the following polynomial as a monomial, binomial, trinomial, or none of these. 2xy + 5 Question 16 options: A) None of these B) Binomial C) Monomial D) Trinomial
Answer:
b) Binomial
Step-by-step explanation:
Binomials, Monomials, Trinomials and etc simply denote the number of terms in the expression. In this case, 2xy is one term, and 5 is another term. That is a total of 2 terms, so it is a Binomial.

A taxi driver wrote a formula to represent the mileage and fee for his last customer. He wrote the equation 3.00 + 0.50 m = 9.50, where m represents the number of miles traveled. Which statement shows the meaning of the driver’s equation? Select two options. Three dollars added to $0.50 is the same as $9.50. Three dollars plus $0.50 times the number of miles is equal to nine dollars and fifty cents. Three dollars more than the quotient of $0.50 and the number of miles is nine dollars and fifty cents. The product of the number of miles and the sum of $3 and $0.50 is equal to $9.50. The sum of three dollars and the product of 50 cents times the number of miles is nine dollars and fifty cents.
Answer: The sum of three dollars and the product of 50 cents times the number of miles is nine dollars and fifty cents.
Three dollars plus $0.50 times the number of miles is equal to nine dollars and fifty cents.
Step-by-step explanation:
Hi, to answer this question we have to analyze the equation given:
3.00 + 0.50 m = 9.50
Where m is the number of miles.
The equation states that the fixed fee charged (3.00) plus the product of the value of each mile traveled (0.50) and the number of miles traveled (m); is equal to 9.50.
So, the correct statements are:
The sum of three dollars and the product of 50 cents times the number of miles is nine dollars and fifty cents. Three dollars plus $0.50 times the number of miles is equal to nine dollars and fifty cents.Feel free to ask for more if needed or if you did not understand something.

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
