You are a dress maker and buy many of your fabrics overseas. You have been given a new design for a dress that each dress
takes 1.5 metres of fabric that you need to buy from a supplier. You are making 12 dresses. The fabric is sold for $22.50 per
yard. How many yards would you need to order and what would it cost you?
Answer:
Total yards = 19.685 yards
Total cost = $442.9125
Step-by-step explanation:
Fabrics per dress = 1.5 meters
Number of dresses = 12
Total fabrics needed = 1.5 meters × 12
= 18 meters
Convert 18 meters of fabrics into yards
18 meters = 19.685 yards
Cost of fabric per yard = $22.50
Total cost of fabrics in yards = 19.685 yards × $22.50
= $442.9125

Answer: 4/3
Step-by-step explanation:
Answer:
-4/3
Step-by-step explanation:
-4/3 Use rise over run. The line went down 4 (hence the negative) and then went over 3. Slope intercept form is -4/3x + 2 or -1.3x + 2. Depending on what they are looking for.
Choose the correct solution for the inequality:
-4x + 5 >-5
A: x < 2.5
B: X > 2.5
C: X <-2.5
D: X > -2.5
Answer:
A
Step-by-step explanation:
We have -4x > -10, so 4x < 10
Answer:
A. x < 2.5
Step-by-step explanation:
you subtract 5 on both sides
then you get -4x > -10.
then you divide -4 on both sides
and you get x<2.5

Answer:
e = 129
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
e is an exterior angle of the triangle , then
e = 60 + 69 = 129

Show the steps of solving. a) 6x - 2y = 28
4x + 2y = 12
PLEASE HELPPPPP I’ll give brainlist!!!
Answer:
x = 4 and y = -2
Step-by-step explanation:
Let 6x - 2y = 28 be equation (i)
and 4x + 2y = 12 be equation (ii)
To solve the following equations, first add the equations:
6x - 2y + 4x + 2y = 28 + 12
6x + 4x + 2y - 2y = 28 + 12
10 x = 40
x = 4
Substituting in (ii)
4x + 2y = 12
4*4 + 2y = 12
2y = 12 - 16
2y = -4
y = -2
the points (-15, -3) and (-7, -1) both lie on the graph of the linear function y =f(x). What is the rate of change of f(x) with respect to x?
F: 4
H: 1/4
G: -4
J: - 1/4
Answer:
Step-by-step explanation:
The rate of change, m, is defined as
m=(y2-y1)/(x2-x1), in this case we have points (-15,-3) and (-7,-1) so
m=(-1+3)/(-7+15)
m=2/8
m=1/4

Step-by-step explanation:
1) [tex]y = x^2 + 4x + 3[/tex]
Lets split the middle term.
[tex]=> y = x^2 + 3x + x + 3[/tex]
[tex]=> y = x(x+3) + 1(x + 3)[/tex]
[tex]=> y = (x+1)(x+3)[/tex]
∴ [tex]x = -3 , -1[/tex]
2) [tex]y = 8x^2 - 22x + 5[/tex]
Lets split the middle term.
[tex]=> y = 8x^2 - 20x - 2x + 5[/tex]
[tex]=> y = 4x(2x - 5) - 1(2x - 5)[/tex]
[tex]=> y = (2x - 5)(4x - 1)[/tex]
∴ [tex]x =\frac{1}{4} , \frac{5}{2}[/tex]
3) [tex]y = x^2 - 5x[/tex]
[tex]=> y = x(x - 5)[/tex]
∴ [tex]x = 0 , 5[/tex]
4) [tex]y = 12x^2 + 18x[/tex]
[tex]=> y = 6x(2x + 3)[/tex]
∴ [tex]x = \frac{-3}{2} , 0[/tex]
5) [tex]y = x^2 - 7x + 12[/tex]
Lets split the middle term.
[tex]=> y = x^2 -3x - 4x + 12[/tex]
[tex]=> y = x(x - 3) - 4(x - 3)[/tex]
[tex]=> y = (x - 3)(x - 4)[/tex]
∴ [tex]x = 3,4[/tex]
6) [tex]y = 3x^2 + 10x + 8[/tex]
Lets split the middle term.
[tex]=> y = 3x^2 + 6x + 4x + 8[/tex]
[tex]=> y = 3x(x + 2) + 4(x + 2)[/tex]
[tex]=> y = (x + 2)(3x + 4)[/tex]
∴ [tex]x = -2 , \frac{-4}{3}[/tex]
7) [tex]y = x^2 - 4x - 45[/tex]
Lets split the middle term.
[tex]=> y = x^2 - 9x + 5x - 45[/tex]
[tex]=> y = x(x - 9) + 5(x - 9)[/tex]
[tex]=> y = (x - 9)(x + 5)[/tex]
∴ [tex]x = -5 , 9[/tex]

Answer:
x = 13.6 in
Step-by-step explanation:
The arc x is calculated as
x = circumference of circle × fraction of circle
= 2πr × [tex]\frac{0.8}{2\pi }[/tex] ( cancel the 2π on numerator/ denominator )
= 17 × 0.8
= 13.6 in
how much is 48 from 12,5%
Answer:
6, but the question makes more sense when asking about 12.5% from 48
Step-by-step explanation:
to get a percentage of something, we just have to remember that [tex]X\% = \frac{X}{100}[/tex] and that we just need to multiply.
Yes, percentages are just numbers, but the percentage sign lets us signify the purpose of a number.
48 * 12.5% = 48 * 0.125 = 48 / 8 = 6

c) x=1.23
Step-by-step explanation:
a =3
b=2
c=-7
use quadratic equation where
[tex] { ax}^{2} + bx + c = 0 = \frac{ - b \: + or \: - \sqrt{ {b} ^{2} - 4ac} }{2a} [/tex]
-2+/- square root of (2^2- (4×3×-7) ) all that over 2x3
square root of (2^2-(4×3×-7) )
= 9.38083152
2×3=6
-2+or - 9.38 all that divided by 6
-2+9.38= 7.38÷6
x=1.23
or
-2-9.38 all divided by 6
-2-9.38= -11.38 ÷6
x= -1.9
all in all x can't be negative meaning x=1.23

Please help me answer the question below, I will give brainliest thing to whoever helps and gets it correct, thank you!
Answer:
y = 1/2 x + 5
Step-by-step explanation:
slope (m) = (y'-y) / (x'-x)
(y-6)/(x-2) = 1/2
y - 6 = 1/2 x - 1
y = 1/2 x + 5
