Given:
- total number of masks= 200
- cost of 1 mask= Rs. 5
so, total cost fir 200 masks=
200×5
= 1000
therefore, Joe paid Rs. 1000 altogether.
Answer:
Step-by-step explanation:
a - 3b = 4 ---------------(eq1)
2a = 6b -9
or, 2a - 6b = -9 ------------(eq2)
2a - 6b = 8 --------(eq1) X 2
2a - 6b = -9 --------(eq2)
(-) (+) (+)
_________________________________
the variable part of both the equations are same. so the equation has more than one solution.
Answer:
416.52 cm cubed
Step-by-step explanation:
first find the volume of the rectangle using LxWxH and you get 360
then get the diamiter of the semi sphere by seing that it is the same size as the width. then to get the radius divide the diamiter by 2. the find the volume of the semi sphere using 2π3^r/3 and you get about 56.52 ( i say about because i used 3.14 instead of all of pie.) then add 360 and 56.52 and you get the volume of this which is 416.52 cm cubed. dont forget the cubed!
could i get brainliest? :)
Answer:
see explanation
Step-by-step explanation:
Given
2z + 4 ≤ - 2 ( subtract 4 from both sides )
2z ≤ - 6 ( divide both sides by 2 )
z ≤ - 3
solution is x ∈ ( - ∞, - 3 ]
The parenthesis on the left means that x cannot equal - ∞
The ] on the right means that x can equal - 3
