Tell whether the statement is TRUE or FALSE. Spheres that have the same length radii are called concentric.

Bas_tet [7]

False
Concentric circles and spheres are those that share the same center. The center of one sphere may be on the circumference of the other while they have the same radius. In that case, they would not be concentric.

Rick used 4 2/3 yards of fabric to sew 3 1/2 shirts. what is the unit rate of cloth he used in terms of yards per shirt

GarryVolchara [31]

For sewing 3 1/2 shirts, he used = 4 2/3 yards of fabric
Then, for 1 shirt, it would be: 4 2/3 / 3 1/2

Fabric for 1 shirt = 14/3 / 7/2
We can re-write it as: 14/3 * 2/7 = 4/3 yards

In short, Final answer would be 4/3 or 1 1/3 yards

Hope this helps!

Please help me:) !!!!!!

Answer:

Please find the solution in the image attached below.

Step-by-step explanation:

Tcos60 -2T sin(90-theta) = 0

Tcos60 = 2T(cos theta)

cos 60 = 2cos theta

cos60 = 2cos theta

1/4 = cos theta

theta = 75.5

So the angle to the vertical = 90-75.5 = 14.5

Resolving perpendicular

Tsin60 + 2Tsin75.5 - 2g = 0

T(sin 60 + 2sin75.5) = 2g

T = 19.6/sin 60 + 2sin75.5

T = 19.6/1.936 + 0.866

T = 19.6/2.802 = 7.0N

Hope this helps!
