Step-by-step explanation:
Since d is an decimal, the higher the power of d, the smaller the value.
A) w + 7 = L
B) w * L = 120
A) w = L -7 then substituting this into B)
(L-7) * L = 120
L² -7L = 120
L² -7L -120 = 0
Solving by quadratic Formula:
L1 = 15
L2 = -8
If length = 15, then width = 8
Answer:
This cylinders volume, in terms of pi, is 144π m³
This cylinders volume, rounded to the hundredth place, is 452.39 m³
Step-by-step explanation:
volume of cylinder:
→ πr²h
→ π(4)²(9)
→ 144π
→ 452.39 m³ ......rounded to nearest hundredth
Answer:
The given triangle is an acute angled triangle.
Step-by-step explanation:
Acute Angle: The angle whose measure is less than a right angle 90 degrees, such an angle is called an acute angle.
Now, here ∠1 = 58° , ∠2 = 50° and ∠3 = 72°
As each of the angle is less than 90° .
⇒ Each angle is an acute angle.
So, the given triangle is an acute angled triangle.
Yes it is because there is a hundredths place
