8/9 in squared
Step-by-step explanation:
because one block is 1/9, and there are 8
Answer:
height = 4 meters
h = 2A / ( a + b )
Step-by-step explanation:
Let A represent the area of the trapezoid, h, the height a, the length of one base and b, the length of the other base
Area of a trapezoid, A = ( a + b)* h / 2
Now let's slot in the given values
A= 18 sq meters
a = 3 meters
b = 6 meters
we have;
18 = ( 3 + 6 ) * h /2
18 = 9 * h /2
Cross multiply
18*2 = 9h
36 = 9h
divide both sides by the coefficient of h (9)
4 = h
therefore, h = 4 meters
To solve for h without substituting
From A = ( a + b )* h /2
cross multiply
2*A = ( a + b )* h
divide both sides by ( a + b )
2A / ( a + b ) = h
therefore,
h = 2A / ( a + b )
If you want to turn a fraction to a decimal, you have to divide the numerator by the denominator in order to get a decimal number. If the fraction is a mixed number, you would do the same but make sure that the whole number is in front of the decimal.
Answer:
The x intercept is (-5,0)
Step-by-step explanation:
1. First, it would be helpful to rewrite the equation to be in y=mx+b form.
5y=4x+20
y=(4/5)x+4
2. Then, plug in 0 for y.
0=(4/5)x+4
3. Then, solve.
-4=(4/5)x
-20=4x
x=-5
