Answer:
900
Step-by-step explanation:
perimeter: P = 2w + 2h
P = 2(20) + 2(25)
P = 40 + 50
P = 90
Multiply perimeter by 10:
90 × 10 = 900
One metre=10 decimetres.
Therefore 30 metres = 30*10=300 decimetres.
Answer:
6\sqrt[4]{x^3}[/tex]
Step-by-step explanation:
6x^3/4
is the same as
6 (x^3/4)
and the rule to change an exponent to a radical is power over root
so in this case, the power, 3 is over the root, 4
So it would be 6\sqrt[4]{x^3}[/tex]
Answer:
13.6 meter
Step-by-step explanation:
Given that :
Suzi's height, p1 = 1.7 m
Suzi's shadow, p2 = 0.3 m
Tree shadow, t2 = 2.4 m
Tree height, t1 =?
Using the relation :
p1 / p2 = t1 / t2
1.7 / 0.3 = t1 / 2.4
Cross multiply :
1.7 * 2.4 = 0.3 * t1
4.08 = 0.3t1
t1 = 4.08 / 0.3
t1 = 13.6
Height of the tree is 13.6 m
Answer:
Step-by-step explanation:
The perimeter is 28".
The total length of three sides of the square = 28-5-5 = 18", so the side length of the square is 18/3 = 6".
The area of the triangle is ½(6)(4) = 12 square inches.
The area of the square is 6² = 36 square inches.
Total area = 12+36 = 48 square inches.
