Answer:
Actual height of the building meters
Step-by-step explanation:
Given
Scale of the drawing
1 cm = 25 meters
This means that any 1 cm line on the map represents a length of 25 meters in actual.
The height of the building on map cm
Actual height of the building
meters
Answer:
The expression has two variables x and y.
Step-by-step explanation:
<u>What is a variable?</u>
A variable is a letter, for instance or , that represents an unknown number.
Given the expression
The given expression has three terms which are x, 4y, and -9.
Here:
- The term 'x' is the unknown variable x.
- The term '4y' has a coefficient (the number next to a variable y) of 4.
- The term '-6' is a constant.
As we already know that a variable is a letter, for instance x or y, that represents an unknown number. In other words, the values of x, or y are unknown to us.
Thus, the expression has two variables x and y.
Answer:
198/7
Step-by-step explanation:
perimeter of semi circle= (pi) x r + d
= 22/7 x 3 + 6
= 198 cm
Answer:
y = 2x
Step-by-step explanation:
We can find the slope
m = (y2-y1)/ (x2-x1)
= (4--4)/(2--2)
= (4+4)/(2+2)
= (8/4)
= 2
We can use the point slope form of the equation
y-y1 = m(x-x1)
y--4 = 2(x--2)
y+4 = 2(x+2)
Distribute the 2
y+4 = 2x+4
Subtract 4 from each side
y+4-4 = 2x+4-4
y = 2x
y+2 = 2x+4
