Answer:
A = 450 cm²
Step-by-step explanation:
Since the right triangle is isosceles then the 2 logs are congruent , both 30 cm and at right angles to each other.
The area (A ) of the triangle is calculated as
A = bh ( b is the base and h the perpendicular height )
Here b = h = 30 , then
A = × 30 × 30 = × 900 = 450 cm²
5 (x - 4) = 3x + 4
5x - 20 = 3x + 4
5x - 3x = 4 + 20
2x = 24
x = 12
I think i did it wrong but 1980 is what i got...i am unsure. hope that helped though:)
If there is 100 grams of sugar syrup, and only 15% of that syrup is sugar, then there is 15 grams of sugar.
Answer: 15 grams of sugar.
1 feet = 12 inches
16 feet = 16 x 12
16 feet = 192 inches
I section = 2 2/3 inches
192 ÷ 2 2/3
= 192 ÷ 8/3
= 192 x 3/8
= 578/8
= 72
It can be cut into 72 sections.
