Answer: 3:1
Step-by-step explanation:
Since the jewellery shops sell 240 necklaces in a month and 180 of the necklaces were sold via the shop's website, this means that (240 - 180) = 60 necklaces were sold in a high street shop.
Therefore, the ratio of online sales to shop sales will be:
= 180 / 60
= 3 / 1
= 3:1
So legnth is 7 more than 6 times width
l=7+6w
area=10 cm^2
lw=area
subsitute
7+6w for l
(7+6w)(w)=10
7w+6w^2=10
subtract 10 from both sides
6w^2+7w-10=0
factor
multiply 6 and -10
get -60
now find what 2 numbers multiply to get -60 and add to get 7
the answe ris -5 and 12
split up 7w into that
6w^2+7w-10=0
6w^2+12w-5w-10=0
group
(6w^2+12w)+(-5w-10)=0
undistribute factors
(6w)(w+2)+(-5)(w+2)=0
reverse distribute (ab+ac=a(b+c)
(w+2)((6w)+(-5))=0
(w+2)(6w-5)=0
set each to zero
w+2=0
subtract 2
w=-2
false, legnths cannot be negative
6w-5=0
add 5
6w=5
divide both sides by 6
w=5/6
subsitute
l=7+6w
l=7+6(5/6)
l=7+5
l=12
legnth=12 cm
width=5/6 cm
Answer:
the first one is scalne the second is isoscles and the third is equailateral
Step-by-step explanation:
scalne- all sides diff lengths
isoscles- two sides same length (remeber the two s in iSoScles)
equaliteral- all sides same length
Answer:
10 units
Step-by-step explanation: Using a coordinate plane, draw a right triangle so the legs are 6 and 8 units long, then use your formula A to the second power + B to the second power equals C to the second power.
