To answer this question you will use the Pythagorean Theorem. a^2+b^2=c^2. In this case a and b are the same because it is a square. So 2x^2=1600 (c^2 where c=40). Solve this equation ( divide both sides by two and find the square root for both). Each side length should be approximately 28.3 cm.
The x-intercept of the graph is (4 , 0)
Step-by-step explanation:
Let us revise the meaning of x-intercept and y-intercept
- x-intercept means value x when y = 0
- That means the graph intersects x-axis at point (a , 0), where a the value of x when y = 0
- y-intercept means value of y when x = 0
- That means the graph intersects y-axis at point (0 , b), where b is the value of y when x = 0
∵ 5x - 4y = 20 is the equation of the graph
- To find x-intercept substitute y by 0
∵ y = 0
∴ 5x - 4(0) = 20
∴ 5x - 0 = 20
∴ 5x = 20
- Divide both sides by 5
∴ x = 4

X=20
26+13+1+8=58
X=2 so 58/2 is 29 so x is 29. And to find the vz you just plug it in 29 into the equation 2x+1 2(29)+1=59
Answer:
929
Step-by-step explanation:
For every 11 children, 7 will have homes and 4 will not.
The fraction of children without homes is 4/11.
The number of children without homes is
4/11 × 2556 = 929
Check:
The number of children with homes is 2556 - 929 = 1627
With/Without = 1627/929 = 7.005/4 ≈ 7/4
OK.
I think its 3,600, because you usually have to multiply the numbers.
