70% i think bc you add 49 and 21 and you get 70 the 49/ 70 is .7 which is 70%
Answer:
20
Step-by-step explanation:
Answer:
Rs. 333
Step-by-step explanation:
Area of the surface of the cuboidal box to be painted = surface area of the cuboidal box - area of the base
✔️Surface area of the cuboidal box = 2(L*W + W*H + L*H)
L = 6 cm
W = 4 cm
H = 2.5 cm
Surface area of the cuboidal box = 2(6*4 + 4*2.5 + 6*2.5) = 2(24 + 10 + 15) = 2(49)
Surface area of cuboidal box = 98 cm²
✔️Area of base = L*W
= 6*4 = 24 cm²
Area of the cuboidal box to be painted = 98 - 24 = 74 cm²
✔️Cost of painting 74 cm² at Rs. 4.50 per cm² = 74 × 4.50 = Rs. 333
Answer:
20/3 - 59/15 = 41/15
6 2/3 - 3 14/15 = 2 and 11/15
Step-by-step explanation:
picture is blurry but if they are similar find the scale between the known sides
smaller triangle bottom looks like it says 8?
the larger one is 16
8/16 = 0.5 so the smaller one is half the size of the larger one
so half of 8 is 4 so y = 4
since they are similar the angles would stay the same so angle B would be the same as s which is shown as 27 degrees.
