Let's use the line on the right side. In the smaller triangle, the length is 4. The same side on the bigger triangle is 12. The ratio of the smaller triangle to the bigger triangle is:
To find a side length for the bigger triangle, all you need to do is multiply by 3. The same side on the smaller triangle is 5. Multiply by 3
That means x = 15
Answer:
602.44
Step-by-step explanation:
13.5 times 10.5 equals 141.75 square feet
then 141.75 times 4.25

Answer:</h3>
- slope = 1/2
- equation: y = 1/2x +5
<h3>
Step-by-step explanation:</h3>
Slope
The slope of the line between two points (x1, y1) and (x2, y2) is ...
... m = (y2 -y1)/(x2 -x1)
For your given points, the slope is
... m = (4 -9)/(-2 -8) = -5/-10
... m = 1/2
Equation
The point-slope form of the equation for a line can be written ...
... y = m(x -h) +k . . . . for a line of slope m through point (h, k)
Using the first point given and the slope just calculated, the equation for the line can be written ...
... y = (1/2)(x -8) +9
... y = (1/2)x -4 +9 . . . . eliminate parentheses; next, collect terms
... y = 1/2x +5
Rhett did because if u look at the graph it lands on -4
400lbs/340ft^2
Factor out largest common factor. LCF is the product of shared primes of the numbers prime factorization.
400=2*2*2*2*5*5, 340=2*2*5*17
So the product of the shared primes is 2*2*5=20, so divide the numerator and denominator by 40.
(400/20)lbs/(340/20)ft^2
20lbs/17ft^2 or if you prefer
(20/17)lbs/ft^2
(1 3/17)lbs/ft^2 or approximately
1.18 lbs/ft^2
