Answer:
The biggest number he can make is 348. Hope this helps!!!
Step-by-step explanation:
You have to multiply 4 and 7 together to get 28. Since if we multiplied every number together, we would end up with a lesser number, since anything multiplied by 1 is itself. Therefore, you next add 1 to 28 to get 29. Finally multiply 29 by 12 to get 348.
Answer:
3.28 feet
Step-by-step explanation:
One meter equals to 3.28 feet.
The question isn't exactly clear what Gema wants to use her wire for, because "wrap one meter" isn't correct.
You wrap something around something else... and you can't wrap something around a meter. You can wrap around a square meter by doing the perimeter... but then you'd need more than meter to do the perimeter of a square meter (the perimeter can be around 4 meters).
So, assuming she has a length of 1 meter to cover, she would need 3.28 feet.
Answer:
The larger acute angle is equal to 50.8 degrees.
Step-by-step explanation:
Let's solve for both of the acute angles for the purpose of checking our work at the end with angle A being the top angle and angle B being the one on the base of the triangle (that's not the 90 degrees one). Determining whether to use sin/cos/tan comes from SOH-CAH-TOA.
A = cos^-1 (2√6/2√15)
However, you need to move the radical out of the denominator by multiplying √15 to the numerator and denominator. You should come up with (2√90)/30. So,
A = cos^-1 (2√90/30) = 50.768 degrees.
B = sin^-1 (2√90/30) = 39.231 degrees.
Now, we can check the work by adding the 2 angles to 90 and, if it comes to 180, it's right.
cos^-1 (2√90/30) + sin^-1 (2√90/30) + 90 = 180.
