Answer:
y = ![\frac{1}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B3%7D)
Step-by-step explanation:
Given
y =
x - 3 ← substitute x = 5
y =
× 5 - 3
=
- 3
=
-
= ![\frac{1}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B3%7D)

Answer:
Surface area of the cube =
Step-by-step explanation:
Given shape in figure 1:
Cube with edge length = 5 cm
To find the surface area of the cube.
Solution:
The surface area of a cube is given by the formula:
![Surface\ Area = 6a^2](https://tex.z-dn.net/?f=Surface%5C%20Area%20%3D%206a%5E2)
where
represents the length of the edges of the cube.
For the given cube ![a=5\ cm](https://tex.z-dn.net/?f=a%3D5%5C%20cm)
Plugging
in the formula to find the surface area of the cube.
![Surface\ Area = 6(5)^2](https://tex.z-dn.net/?f=Surface%5C%20Area%20%3D%206%285%29%5E2)
∴ ![Surface\ Area = 6\times 25 = 150\ cm^2](https://tex.z-dn.net/?f=Surface%5C%20Area%20%3D%206%5Ctimes%2025%20%3D%20150%5C%20cm%5E2)
Answer:9/4
Step-by-step explanation:multiply 2.25 by 100 so you get 225/100 and reduce
Answer:
1:3
Step-by-step explanation:
First, you need to make a system of equations for the situation.
Let G represent the number of girls and B represent the number of boys.
Since there are twice as many girls as boys,
G = 2B
There are a total of 30 students in class so,
G + B = 30
or
G + B = TOTAL
In order to find the ratio of BOYS to the TOTAL STUDENTS,
you plug in B values that make up G.
(2B ) + B = TOTAL
3B = TOTAL
B = TOTAL / 3 or (1/3) TOTAL
Since B is one third of the total number of students, the ratio is 1:3.
