Answer:
dissect the trapezium into a square and triangle. since the triangle is a right angled one the base is 17-7=10cm
the height is found using Pythagorean theorem to be 24cm i.e 26²=x²+10²,x=√(676-100),x=√576,x=24cn
area of trapezium is (1/2)(a+b)h
a is the shorter side and b the longer side
(1/2)*(7+17)24
=288cm²
For this problem you have yo set up two equations.
White shirts = w Yellow shirts = y
1st: w + y = 21
2nd: 9.95w + 11.50y = 235.30
Now we're going to do system of equations using substitution.
If w + y = 21, then y = 21 - w
If y = 21 - w, then you can substitute this in the second equation for y.
9.95w + 11.50(21 - w) = 235.30
9.95w + 241.5 - 11.50w = 235.30
-1.55w + 241.5 = 235.30
-1.55w = -6.2
w = 4, so 4 whites shirt were sold.
Now I'm finding out how many yellow shirts were sold using one of the two equations at the top.
w + y = 21
4 + y = 21
y = 17
So 17 yellow shirts were sold and 4 white shirts were sold.
Answer:
A variable is an input variable if its Input property is Yes. Its value can be input from an external source, such as an Architect call flow. A variable whose Output property is Yes is an output variable.Since both properties can be set to yes, a variable can be both an input variable and an output variable.
Step-by-step explanation:
we have
Step 
Move the constants to the right side
Step 
Factor 3 out of the variable terms
Step 
Add 
to both sides of the equation
Step 
Write the polynomial as a binomial squared
therefore
the answer is
Factor 3 out of the variable terms.
Answer:
1.627 miles
Step-by-step explanation:
longest distance - 2.55 miles
shortest distance - 0.923 miles
difference = 2.55-0.923
=1.627 miles
