By writing an equation you can easily solve this:
18+ X + 4X - 1 = 42
•we need the answer to 4X-1
1. put the parts that include the X parameter in one side and the integer numbers in one side :
X + 4X = 25
5X= 25
X= 5
2. 4X-1 —> 4x5-1 = 19
Volume of a cylinder = pi r^2 h where r = radius of the base and h = the height.
so if we are given a radius of 2 cm and a volume of 180 cm^3 we work out the height as follows:-
180 = pi * 2^2 * h
h = 180 / (pi*2^2)
height h = 180 / 4pi = 14.32 cm to nearest hundredth
Answer:
A: 38º
Step-by-step explanation:
Triangle JKL is an isosceles triangle as JK=KL:
- That means ∠J=∠L=71º
- The sum of a triangle's interior angles is 180º, so ∠K=180º-∠J-∠L. We know ∠J=∠L=71º, so ∠K=180º-71º-71º=38
