Answer:
2.) 7.8
Step-by-step explanation:
We can use Pythagorean theorem
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
5^2 + 6^2 = c^2
25+36 = c^2
61 = c^2
Take the square root of each side
sqrt(61) = sqrt(c^2)
7.810249676 = c
Answer:
3.6
Step-by-step explanation:
The ratio of bows to headbands is 8:4. This means that for every 8 bows, there are 4 headbands, Then, a true statement is the second option.
Since there are 8 bows + 4headbands = 12 accessories, this also implies that for every 12 hair accesories, there are 4 headbands. This solution corresponds to the last option.
Hence, the true statements are the second and last options.
Answer:
The correct equation is: n + 2.2 = 5
The solution is: n = 2.8
Step-by-step explanation:
Sum is addition,
so the correct equation is:
n + 2.2 = 5
The solution is:
n = 2.8
Verification:
2.8 + 2.2 = 5
5 = 5 (true)
It would be 1.70
Hope this helps!
