Length could be 9 width could be 8. Because 8 times 9 is 72.
slope =0.5 and y intercept 4/5
Step-by-step explanation:
5x-10y =-8
5x+8= 10y
5x/10+8/10=10/10
1/2x+4/5 = 1
B. the temperature of a liquid after it is heated for 10 seconds
The problem statement is not clear regarding which money is invested. We will assume it is the 80% of $8750 that is set aside for future education. That amount is
... 0.80 × $8750 = $7000
If x represents the amount invested at 7%, then the total interest earned is
... (7000 -x)×4% + (x)×7% = 420
... 280 +0.03x = 420
... x = 140/0.03 ≈ 4666.67
$4666.67 was invested at 7%.
$2333.33 was invested at 4%.
Answer:
I think it's called the Converse of the Pythagorean. This tells us that if the square of one side of a triangle is equal to the sum of the squares of the other two sides, then the triangle is a right triangle.To do this you just plug in the numbers where c is the largest among a,b,c. ( in case you forgot a and b are bases and the c is called the hypotenuse)
