Answer:
Yes, she can drew a right triangle with these sides
Step-by-step explanation:
To answer this question we first have to prove the Pythagorean theorem
h = hyoptenuse
a = leg 1
b = leg2
h² = a² + b²
We have to replace the values that they gave us in this formula
The hypotenuse always has to be the longest side of a right triangle
(14cm)² = (11.2cm)² + (8.4cm)²
196cm² = 125.44cm² + 70.56cm²
196cm² = 196cm²
As we can see, equality is fulfilled, so she is correct
Answer:
The total cost to install the 1,200 ft of the pipe is $21000.
Step-by-step explanation:
Consider the provided information.
You buy 900 ft pipe with a cost of $15 per foot and the remaining 300 ft pipe with a cost of $25 per foot.
Therefore, the total cost is:
Hence, the total cost to install the 1,200 ft of the pipe is $21000.
Let's construct an equation for Canton's population increase as 7220+80n and Holly Spring's population increase with 3200+120n, where n is the number of years. We have to set these equations to each other in order to find when the population of these two places are equal. 3200+120n=7220+80n and n=100.5. After 100 and half years
4y + 8x = 112
V = x*x*y= x^2y
y + 2 x = 28
y = 28 - 2x
V = x^2 (28-2x) = 28 x^2 - 2 x^3
