Answer:
36 yards of fabric
Step-by-step explanation:
Set up the proportion
quilts/yards = quilts/yards
Let x = no. of yards to make 12 quilts
x/12 = 21/7 = 3
x = 12(3) = 36 yards of fabric

Answer:
7. 6
8. 6
9. 12
10. 6
11. 12
12. 24
Step-by-step explanation:
The length of each segment is AB = 6, BC = 6, AC = 12, CD = 6, CE = 12, AE = 24
What is the length?It is the measure of distance between the two points is called a length.
D is the mid-point of CE. Then
CD = DE = 6
B is the mid-point of AC. Then
AB = BC
C is the mid-point of AE. Then
AC = CE
AB + BC = CD + DE
AB + AB = CD + CD
2 AB = 2 CD
AB = CD
AB = 6
Then
AB = 6
BC = AB = 6
AC = AB + BC = 6 + 6 = 12
CD = DE = 6
CE = CD + DE = 6 + 6 = 12
AE = AB + BC + CD + DE = 6 + 6 + 6 + 6 = 24

Step-by-step explanation:
A limited-edition poster increases in value each year with an initial value of $18. After 1 year and an increase of 15% per year, the poster is worth $20.70. Which equation can be used to find the value, y, after x years? (Round money values to the nearest penny.) y = 18(1.15)x
Answer:
[tex]y = 18 * 1.15^x[/tex]
Step-by-step explanation:
Given
[tex]a = 18[/tex] --- initial
[tex]r =15\%[/tex] -- rate
Value after a year = $20.70
Required
Expression to calculate its value after y years
This is calculated using:
[tex]y = ab^x[/tex]
Where
[tex]b=1 +r[/tex]
Substitute [tex]r =15\%[/tex] in [tex]b=1 +r[/tex]
[tex]b = 1 + 15\%[/tex]
[tex]b = 1 + 0.15[/tex]
[tex]b = 1.15[/tex]
Substitute [tex]b = 1.15[/tex] and [tex]a = 18[/tex] in [tex]y = ab^x[/tex]
[tex]y = 18 * 1.15^x[/tex]

Answer:
Option C
Step-by-step explanation:
Domain is the set of x-values of the function.
Similarly, Range of a function is defined by the set of y-values of the function.
For the given set of domain → {0, 3, 7}
Range of function → f(x) = 2ˣ + 4
x 0 3 7
f(x) 2⁰+ 4 = 5 2³+ 4 = 12 2⁷ + 4 = 132
Therefore, range of the given function will be → {5, 12, 132}
Option C will be the answer.

- You invest $80 into a simple interest savings account that earns 5% annually.
After how many years will the account have a total of 200$ in it?
Answer:
30 years.
Step-by-step explanation:
The equation for simple interest is I = PRT, where I = interest earned, P = principal/amount invested, R = rate as a decimal, and T = time in years.
Our unknown for this example is T, but first we have to see how much interest is earned.
200 - 80 = 120 in interest (starting with $80, ending with $200)
120 = (80)(0.05)(T)
120 = 4T
30 = T

Find the perimeter of the composite shape shown below.
A.50m
B.30m
C.90m
B.42m
(pythagoras theorem | year 9)
Answer:
In this case, to prove what is required, we must use the Pythagorean theorem to find the diagonal of the square.
If the diagonal of the square is smaller than the diameter of the circle, then the square will fit perfectly in the circle without touching it.
Diagonal = Root ((7 ^ 2) + (7 ^ 2)) = 9.89 cm.
we observed that
9.89cm <11cm.
Therefore we show that:
the square will fit inside the circle without touching the edge of the circle
or
c^2 = a^2 + b^2 c^2 = 7^2 + 7^2 = 49 +49 c^2 = 98 c = sqrt 98 c = 9.8 cm c = diagonal of square (9.8 cm) and is less than the diameter of the circle (11 cm), so the square will fit inside the circle without touching the edge of the circle.

The first triangle is dilated to form the second triangle. What is the scale factor? Please show your math work step by step.
Answer:
2.5 is the scale factor
Step-by-step explanation:
Skills needed: Identifying the Scale Factor, Division
1) First, we need to understand what the scale factor is.
A scale factor is the value being multiplied by one side of a figure to form another figure that is bigger or smaller. For example:
Let's say you are given a triangle with side lengths 3 cm, 4 cm, and 5 cm and you are supposed to find the side lengths of a new triangle when the scale factor being used is 2. Here, you would multiply all the sides by the value 2. So, the 3 sides are:3 x 2, 4 x 2, and 5 x 2 ---> 6 cm, 8 cm, 10 cm.
2) So to find the scale factor in a problem, you would do the side of one triangle divided the corresponding side of the other triangle.
So to find the scale factor in the above problem (if we were only given side lengths 3 cm, 4 cm, and 5cm & also 6 cm, 8 cm, and 10 cm), you would do:
[tex]\frac{6}{3}[/tex] or [tex]\frac{8}{4}[/tex] or [tex]\frac{10}{5}[/tex], all of which equal 2.
3) So in this problem, you would simply do [tex]\frac{10}{4}[/tex], since 10 and 4 are corresponding sides of dilated triangles.
This is [tex]\frac{5}{2}[/tex] when simplified, or 2.5 as a decimal, since scale factors are usually expressed as decimals.
Hope this helps and have a nice day!! :) :] :D
Create an equation to solve for x using the trapezoid midsegment formula:
Answer:
Equation for x: 3x - 6 = [tex]\frac{2x - 1 + 25}{2}[/tex]
x = 9
CD = 17
GH = 21
Step-by-step explanation:
The midsegment formula for a trapezoid is
GH = [tex]\frac{CD + FE}{2}[/tex]
3x - 6 = [tex]\frac{2x - 1 + 25}{2}[/tex]
6x - 12 = 2x + 24
4x = 36
x = 9
CD = 2x - 1 = 2(9) - 1 = 18 - 1 = 17
GH = 3x - 6 = 3(9) - 6 = 3 = 27 - 6 = 21

This is the third time that I am asking the same question!
Answer:
Step-by-step explanation:
10)
P10 = (2,7)
and parallel to y -4x = 5
y = 4x + 5
so any thing with a slope of 4 but going thur P1
y-7 = 4(x-2)
y-7 = 4x -8
10) y = 4x -1
11)
P11 = (5,-1)
and parallel to
y = -1/2x + 2
anything with a slope of -1/2 but going thur P2
y- (-1) = -1/2(x-5)
y + 1 = -1/2x +5
11) y = -1/2x + 4
12)
P12 = ( 3, 0 )
-2y + 3x = 0
perpendicular to, so the slope is reciprocal and opposite sign
3x = 2y
3/2x = y
y = 3/2x
-2/3 is the perpendicular slope
y-0 = -2/3(x-3)
12) y = -2/3x + 2
13)
P13= ( 6, 3)
3x- y = 6
perpendicular to, so the slope is reciprocal and opposite sign
3x-6 = y
y = 3x -6
-1/3
y-3 = -1/3(x-6)
y-3 = -1/3x + 2
13) y = -1/3x + 5
Simplify and leave in radical form.
Answer:
Step-by-step explanation:
Expressing in simplest radical form just means simplifying a radical so that there are no more square roots, cube roots, 4th roots, etc left to find. It also means removing any radicals in the denominator of a fraction.
