Answer:
No, it is not a right triangle.
Step-by-step explanation:
The simplest way to determine is testing out the numbers with Pythagorian theorem.
If it complies with the theorem, it is a right triangle.
let's assume c = 28, b = 21, and a = 20
the longest side is the hypotenuse so side c (28 in) will be the hypotenuse.
According to the Pythagorian theorem, the square of the length of hypotenuse must equal to the sum of squares of other two sides.
check:
c^2 = 28^2 = 784
a^2 + b^2 = 21^2 + 20^2 = 841
because c^2 is not equal to a^2 + b^2, the triangle is not a right triangle.
Answer:
28
Step-by-step explanation:
When you put the numbers in order and then cut into 4 equal parts 28 is the first cut
sorry idk if that made sense or not
Answer: Janey has $115, and Teresa has $230.
Step-by-step explanation:
Set x be the money that Janey have, then Teresa have 2x.
x + 2x = 345
3x = 345
x= $115
2x= 2(115)= $230
Answer:

)
Step-by-step explanation:
When factoring an expression like this, you need to divide all of the parts by a common number or variable. In this case, the only thing all of these numbers share is that they are divisible by 648. So, you would divide each number by 648 to simplify it, getting 1, 3, 4, and 2. Put these numbers in front of their respective variables, and put 648 outside of the parentheses to get the final answer.
The amount of milk containing 6% butterfat and 1% butterfat are 260 gallons and 65 gallons respectively.
<u><em>Explanation</em></u>
Suppose, the amount of milk containing 6% butterfat is
gallons
As the amount of mixture of milk should be 325 gallons, so the amount of milk containing 1% butterfat will be:
gallons
Given that, the mixture of milk is containing 5% butterfat. So, the equation will be....

So, the amount of milk containing 6% butterfat is 260 gallons and the amount of milk containing 1% butterfat is (325-260) gallons = 65 gallons.
