Answer:
14/1.8 = x/4
Step-by-step explanation:
Using similar triangles,
height of man/length of man's shadow = height of tree/length of tree's shadow
1.8/4 = x/14
x/14 = 1.8/4
If we cross-multiply, we have
1.8 × 14 = x × 4
dividing both sides by 4 and 1.8,we have
14/4 = x/1.8
x/1.8 = 14/4
So, the two expressions we have are
x/14 = 1.8/4 and x/1.8 = 14/4.
So, the answer is 14/1.8 = x/4 since the product 1.8 × 14 = x × 4 cannot be expressed in the given ratio.
Area of ABCE:
12 x 4
= 48cm squared
Area of CDE:
To get the height of the triangle, you subtract 4 from 10.
10 - 4 = 6cm
Base = 12 cm
12 x 6 = 72cm
72 divided by 2
= 36cm squared.
48 + 36 = 84cm squared.
(if it’s asking individual areas, then it’s 48cm and 36cm)
Answer:
I guess D is the answer for the question
Since it's a cube all the side lengths are the same. So the calculation would be 6.1x6.1x6.1 or 6.1^3
V=226.981cm^3
V=Length x width x heigh

Answer:
I assume your goal is to rationalize the denominator -
So you need to multiply the denominator by its conjugate.
So we have:
