Answer: 60
Step-by-step explanation:
Answer: the original jacket is 60$
Step-by-step explanation:
x -18$ = 30%
therefore 36 off would be 60% off
so to get 30% to 100 % you need to multiply it by 3 1/3
18*3 1/3 = is 60
Hope this helps! <3

A 10-gal aquarium is 4 in. higher than it is wide. Its length is 17 in., and its volume is 4284 in.^3. What are the height and width of the aquarium?
Answer:
[tex]W = 18[/tex] -- Width
[tex]H = 14[/tex] --- Height
Step-by-step explanation:
Given
[tex]V = 4284[/tex] -- Volume
[tex]L = 17[/tex] -- Length
[tex]H = ??[/tex] -- Height
[tex]W = 4 + H[/tex] -- Width
Required:
Find the height and the width
Volume is calculated as:
[tex]V = LWH[/tex]
This gives:
[tex]4284 = 17 * (4+H) * H[/tex]
[tex]4284 = 17 * (4H+H^2)[/tex]
Open bracket
[tex]4284 = 17 * 4H+17*H^2[/tex]
[tex]4284 = 68H+17H^2[/tex]
Divide through by 17
[tex]252 = 4H+H^2[/tex]
Write as a quadratic expression
[tex]H^2 + 4H - 252 = 0[/tex]
Expand
[tex]H^2 + 18H - 14H - 252 = 0[/tex]
Factorize:
[tex]H(H + 18) - 14(H + 18) = 0[/tex]
Factor out H + 18
[tex](H - 14)(H + 18) = 0[/tex]
[tex]H -14 = 0[/tex] or [tex]H + 18 = 0[/tex]
[tex]H = 14[/tex] or [tex]H = -18[/tex]
But Height can not be negative. So:
[tex]H = 14[/tex]
Recall that:
[tex]W = 4 + H[/tex]
[tex]W = 4 + 14[/tex]
[tex]W = 18[/tex]

Prove that if x and y are rational then their product is also rational. First write a proof on your own and then put the following statements into order to obtain the proof. Put N next to the statements that should not be used in the proof. 1. Then, xy=acbd . 2. Suppose x and y are arbitrary rational numbers. 3. Since a, c are integers, e=ac is also an integer.
Answer:
Step-by-step explanation:
The aim of this question is to prove that the product of two rationals is rational.
To proof:
If [tex]\mathbf{x \ and \ y}[/tex] are arbitrary rational numbers.
Thus, going by the definition of rational, there exist integers
a, b, ≠ 0, c, and d ≠ 0 ; [tex]x = \dfrac{a}{b} \ and \ y = \dfrac{c}{d}[/tex]
Hence, [tex]xy = (\dfrac{a}{b})(\dfrac{c}{d}) = \dfrac{ac}{bd}[/tex]
Since a and c are integers, then e = ac appears to be an integer as well.
Also, provided that b and d are non-zero integers;
f =bd appears to be a non-zero integer.
Therefore, [tex]xy = \dfrac{e}{f}[/tex], and going by the definition of rational, xy is rational.
Hence, from the complete question:
The order of the statement is:
7,6,3,5,2,4
The statements that should not be used in the proof are:
1 N
8 N
9 N
10 N
11 N

Law of Sines: sin A
sin B
b
sin C
С
a
Enter
========================================================
Explanation:
The ultimate goal is to find the value for lowercase c, or find the length of side c. So we'll use the portion sin(C)/c as part of the law of sines.
We don't know the value of lowercase 'a', so we'll ignore the sin(A)/a portion.
This leaves sin(B)/b
We see that one side is 2 cm long, so this means b = 2. The angle opposite this is 105 degrees, so B = 105.
The angle opposite side c is 15 degrees, so C = 15.
The lowercase letters represent side lengths, while the uppercase letters are angles.
--------------------------
We have enough to apply the law of sines to solve for side c.
sin(B)/b = sin(C)/c
sin(105)/2 = sin(15)/c
c*sin(105) = 2*sin(15) ............. cross multiply
c = 2*sin(15)/sin(105) .............. dividing both sides by sin(105)
c = 0.53589838486224
c = 0.5
Side c is roughly 0.5 cm long.
Make sure your calculator is in degree mode.
9514 1404 393
Answer:
0.5 cm
Step-by-step explanation:
The Law of Sines tells you ...
c/sin(C) = b/sin(B)
c = b·sin(C)/sin(B)
c = (2 cm)sin(15°)/sin(105°) ≈ (2 cm)(0.2588/0.9659) ≈ 0.5359 cm
c ≈ 0.5 cm . . . . rounded to tenths
actor 14x+7y using the GCF.
Answer:
so to factor out you find the greatest common factor of 14 and 7
if you have 2x-2 then you can factor out the 2 and get 2(x-1)
7=7*1
14=2*7
the greatest common factor is 7
14x-7=7(2x-1)

A triangle has a perimeter of 112 cm. Each of the two longer sides of the triangle is three times as long as the shortest side. Find the length of each side of the triangle.
Answer:
Two sides have a measure of 48 cm and the shortest side is 16 cm.
Step-by-step explanation:
this is an isosceles triangle
let x = length of shortest side
let 3x = length of other two sides
find x:
3x + 3x + x = 112
7x = 112
x = 16
3x = 48
What fraction could be between 3/4 and 5/6 ? HOW do you know ?
Answer:
4/5
Step-by-step explanation:
3/4=0.75
5/6=0.83
4/5=0.8
Answer:
Step-by-step explanation:
There actually is an infinite number of fractions between 3/4 and 5/6. But to find a simple ones make the denominators the same.
(3/4)(6/6) and (5/6)(4/4)
18/24 and 20/24 so 19/24 is halfway between them.
