Answer:
x =1
Step-by-step explanation:
7x + 10= 18x -1 ==> 7x - 18x = -1 -10 ==> -11x = -11 ==>x = 1
Answer:
The required Expression is
![-90 \geq 18x](https://tex.z-dn.net/?f=-90%20%5Cgeq%20%2018x)
Also for x Divide by 18 on both the side
![\dfrac{-90}{19}\geq \dfrac{18x}{18}\\\\-5\geq x\\\\x\leq -5](https://tex.z-dn.net/?f=%5Cdfrac%7B-90%7D%7B19%7D%5Cgeq%20%5Cdfrac%7B18x%7D%7B18%7D%5C%5C%5C%5C-5%5Cgeq%20x%5C%5C%5C%5Cx%5Cleq%20-5)
Step-by-step explanation:
-90 greater than or equal to 18x
.
It is the Algebraic Expression in Statement form.
Algebraic Expression is given in the form numbers and variables with the operands such as,
' + ' Plus Sign
' - ' Minus Sign
' > ' Greater Sign
' = ' Equal Sign
' ≥ ' Greater than or Equal to Sign ,etc.
Here -90 Greater than or Equal 18 x
Therefore , -90 ≥ 18x
The required Expression is
![-90 \geq 18x](https://tex.z-dn.net/?f=-90%20%5Cgeq%20%2018x)
Also for x Divide by 18 on both the side
![\dfrac{-90}{19}\geq \dfrac{18x}{18}\\\\-5\geq x\\\\x\leq -5](https://tex.z-dn.net/?f=%5Cdfrac%7B-90%7D%7B19%7D%5Cgeq%20%5Cdfrac%7B18x%7D%7B18%7D%5C%5C%5C%5C-5%5Cgeq%20x%5C%5C%5C%5Cx%5Cleq%20-5)
Answer:
I belive it’s C
Step-by-step explanation:
I don’t know if it’s correct tell me if I’m wrong
Yes. On a circular path, the direction of motion is constantly changing. Change of direction is acceleration, even at constant speed.
Answer: The answer is (D) A cylinder is exactly 3 times bigger than a cone with the same height and radius. Therefore, the formula for the volume of a cone is 1/3 of the volume of a cylinder with the same height and radius.
Step-by-step explanation: We know that a Cone is a three-dimensional geometric figure with a circular base as shown in the attached figure (a). In fact, a Cone is a pyramid with a circular cross-section.
The volume of a Cone and a Cylinder are related to each other. The volume of a cylinder is
![V_{cylinder}=\pi r^2h](https://tex.z-dn.net/?f=V_%7Bcylinder%7D%3D%5Cpi%20r%5E2h)
and the volume of a cone is
![V_{cone}=\dfrac{1}{3}\pi r^2h.](https://tex.z-dn.net/?f=V_%7Bcone%7D%3D%5Cdfrac%7B1%7D%7B3%7D%5Cpi%20r%5E2h.)
Therefore, if the radius of the base and height of a cone and a cylinder are same, the the volume of the cone is one-third of the volume of cylinder. So, we can join 3 cones together to form a single cylinder having radius and height equal to the radius of base and height respectively of the cone. See the attached figure (b).
Thus, the correct option is (D).
