Answer:
The height of the tree is 30 feet
Step-by-step explanation:
Let
h ----> the height of the tree
we know that
The tree casts a shadow that is 27 feet long
Your friend is 5 feet tall and casts a shadow that is 4.5 feet long
so
using proportion
Find out the height of the tree
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
4^3*4^-5= 4^-2 (add the exponents since the base is the same)
5^-4*5^1= 5^-3 (add the exponents since the base is the same)
Square both terms (double the exponents)
(4^-2)^2= 4^-4
(5^-3)2= 5^-6
Then take out negative exponents (x^-a= 1/x^a)
4^-4 /5^-6 = 5^6/4^4
Final answer: 5^6/4^4
If you want it in number form
5^6= 15625
4^4=256
15625/256= 61.035...
H because it passes the vertical line test
