11 lbs 5 oz - 1 lb 15 oz...we are gonna have to borrow...there is 16 oz in a lb.
11 lbs 5 oz....we r going to borrow 1 lb from the right side and add it to the left side making it 10 lbs and 21 oz...u see what I did...I borrowed 1 lb from the right side and added 16 oz to the left.Now we can subtract.
10 lbs 21 oz - 1 lb 15 oz = 9 lbs 6 oz <== ur answer
Answer:
18
Step-by-step explanation:
x² = 16² + 30² - 2(16)(30)cos 30°
x² = 256 + 900 - 960(0.866)
x² = 1156 - 831.36
x² = 324.64
x = 18.02
Approx. 18

Answer:
<em>90 degrees</em>
<em>90 degreesPerpendicular lines are lines that intersect at a <u>right (90 degrees) angle.</u></em>
A tetrahedron is a triangular pyramid. It has four triangular faces and four vertices.
In the question, we are told that the length of the edges are all equal = 20m and the length from one corner to the center of the base = 11.5m
We sketch a diagram of a tetrahedron with the given measurement as shown below
To find the height, we will use the Pythagoras theorem
20² = h² + 11.5²
h² = 20² - 11.5²
h² = 267.75
h = √267.75
h = 16.36 (rounded to two decimal places)
Answer:
oc
Step-by-step explanation:
because it's oc so the side is wrong and the vertex too
