Answer: 50 students
Step-by-step explanation:
You know that the number of students last year plus 20% of that number equals the number of students this year, which can be written as: x + 0.2x = 60 →
1.2x = 60 → x = 50 students :)
Well one is positive and one is negative
Answer: 2.5, 17.5
Step-by-step explanation: I'm kinda confused at what those big blue things with numbers are... but im guessing that's just used to indicate the missing values. So 10/4 = 2.5, meaning the ration is 2.5 pounds per week. So 1 week is 2.5 pounds, and 7 weeks is 2.5*7 = 17.5
Given:
Length of a cube is 2 cm
To Find:
Surface area of the cube
Solution:
A cube consists of 6 faces.
The area of each face = side x side
So, the total surface area of a cube = 6 x
side x side
Let a be the length of the given cube
: Surface area of a cube = 6a square
a = 2 cm (Given)
Surface area of cube = 6 x 22 =(6 x 4) = 24 cm square.
Hence, the surface area of the given
cube is 24cm square.
