Answer:
r = 80 KM/HR
w= 30 CM/HR
Step-by-step explanation:
Answer:
Area: T = 3
Sides: a = 2.828 b = 2.236 c = 3
Step-by-step explanation:
Angle ∠ A = α = 63.435° = 63°26'6″ = 1.107 rad
Angle ∠ B = β = 45° = 0.785 rad
Angle ∠ C = γ = 71.565° = 71°33'54″ = 1.249 rad
Hope this helps!
Have a good day!

The answer is <span>49x2 _ 84x + 36
</span>
(7x - 6)² is the square of the difference. The general formula would be:
(a - b)² = a² - 2ab + b²
In our expression (7x - 6)², a would be 7x and b would be 6:
(7x - 6)² = (7x)² - 2 · 7x · 6 + 6²
= 7² · x² - 84x + 36
= 49x² - 84x + 36
Answer:8.385
Step-by-step explanation:
Step 1: multiply both sides by 30 (this sounds crazy, but that's 5 and 6's least common multiple) 1/6(j-1)+4=1/5(3j+1) -> 5(j-1)+120=6(3j+1)
Step 2: Distribute 5(j-1)+120=6(3j+1) -> 5j-5+120=18j+6
Step 3: Combine like terms 5j-5+120=18j+6 -> 5j+115=18j+6
Step 4: Isolate the variable 5j+115=18j+6 -> 109=13j
Step 5: Divide to further isolate 109/13=j= 8.385
Answer:
hypotenuse is 22.47 m
Step-by-step explanation:
The length of both legs of a right angle triangle are 8m and 21 m
We need to find the hypotenuse
To find hypotenuse we use Pythagorean theorem
Hypotenuse is AC and other two legs are AB and BC
Hypotenuse ^2 = 8^2 + 21^2
hypotenuse =
=
=
= 22.47
So the length of the hypotenuse is 22.47 m
