So this is a Pythagorean problem where
A^2+b^2=c^2
a is 2
X is b
5 is c
Plug that into the equation and get
4+b^2=25
B^2=21
B=sqrt(21)=4.6kilometer
The statement that is true about the factorization of 30x2 + 40xy + 50y2 is that <span>The factorization of the polynomial is 10(3x2 + 4xy + 5y2).</span>
Answer:
2/5 of a Mile
Step-by-step explanation:
Total mikes from school to Steven house = 3/5 of a Mile
If Steven walked 2/3 of the way there, the distance he walked =2/3×3/5 = 2/5
If he stopped the rest, then the distance he travelled before stopping is 2/5 of a Mile
Answer:
Step-by-step explanation:
Answer: c.
Explanation: The first thing you do when you subtract mixed numbers is convert them into improper fractions. 4 3/4 can be converted to 19/4 and 1 1/3 can be converted into 4/3. To be able to subtract or add fractions they need to have the same denominator a number in which both denominators can go into and that number is 12. 4 can equally go into 12 and so can 3. Now that you have found the common denominator (12) you have to find out what kind of operation you need to do in order for 4 to be 12 and for 3 to also be 12. And that is by multiplying. If you multiply 4 by 3 and get 12 and 3 by 4 to get 12 as well. Whatever you do to the bottom of the fraction you also do to the top so 19 x 3 / 4 x 3 = 57/12. Do the same to the other improper fraction: 4 x 4/ 3 x4 = 16/12. They both now have the same denominator but you have to subtract so,,57/12 - 16/12 = 41/12 you have the answer to the subtraction problem but you can probably tell that it isn’t any of the options on the question. Simplifying 41/12 will give you the mixed number 3 5/12.
