by angle sum property of triangle,
70+60+(x+60)=180
=> 190 +x = 180
=> x = 180-190
=> x = -10
-6x=-2(x+12) Given
-6x=-2x-24 Distributive Property
-4x=-24 Addition Property of Equality
x=6 Division Property of Equality
Answer:
Area = 228 m²
Perimeter = 60 m
Step-by-step explanation:
The figure given shows a rectangle that has a cut triangular portion.
✔️Area of the figure = area of rectangle - area of the triangular cut portion
= L*W + ½*bh
Where,
L = 20 m
W = 12 m
b = 20 - (8 + 8) = 4 m
h = 6 m
Plug in the values
Area = 20*12 - ½*4*6
Area = 240 - 12
Area = 228 m²
✔️Perimeter = perimeter of rectangle - base of the triangular cut portion
= 2(L + W) - b
L = 20 m
W = 12 m
b = b = 20 - (8 + 8) = 4 m
Plug in the values
Perimeter = 2(20 + 12) - 4
= 2(32) - 4
= 64 - 4
Perimeter = 60 m
Answer:
2923.34 in^3
Step-by-step explanation:
Volume = Pi x (r) ^2 x height
PI =3.14,
, R = 7inch (d =radius /2 >> 14/2)
H =19 inch
Volume = 3.14 x 49in^2 x 19 inch
= 2923.34 in^3
Answer:
Ratio of online sales to shop sales = 3 : 1
Step-by-step explanation:
Total necklace sold in a month = 240
Necklace sold via shop's website = 180
the rest were sold in a high street shop.
Necklace sold via high street shop = Total necklace sold in a month - Necklace sold via shop's website
= 240 - 180
= 60
Necklace sold via high street shop = 60
Ratio of online sales to shop sales
Necklace sold via shop's website : Necklace sold via high street shop = 180 : 60
= 180 / 60
= 3 / 1
= 3 : 1
Ratio of online sales to shop sales = 3 : 1
