Answer:

B. 252

Step-by-step explanation:

To find the answer, you have to use the formula to calculate the number of combinations as in this case, the order in which the objects are selected doesn't matter:

nCr=n!/r!(n-r)!

n= number of sample points: 10

r= number of sample points in each combination: 5

10C5= 10!/5!(10-5)!

10C5= 10!/5!*5!

10C5= 252

According to this, the answer is that you have 252 different ways to choose your school lunch.

a rectangular prism measures 3 in by 8 in by 9 in. what is the side length of a cube with the same volume?
Novay_Z [31]

Answer:

6 in.

Step-by-step explanation:

Rectangular prism

V = lwh       l = 8   W = 3    h = 9

  = 8(3)(9)

  = 216

Cube

V = s^{3}   where s = length of side

216 = s^{3}

s = \sqrt[3]{216}  = 6

Anyone know this please???
Kazeer [188]

Answer: Choice A

The triangles are congruent because both the corresponding sides of the triangles and the corresponding angles of the triangles are congruent.

==============================================

Explanation:

Congruent triangles are identical copies of one another. This means the corresponding pieces must be the same.

It's like saying two houses are identical, so that means the all the various parts (eg: front door, windows, etc) must be identical. If let's say the two front doors were different, then the houses wouldn't be completely identical.

Going back to the triangles, we know that the sides are congruent by the tickmarks

  • side MN = side RS (single tickmark)
  • side NP = side ST (double tickmarks)
  • side MP = side RT (triple tickmarks)

That takes care of the first part of choice A.

And similarly, the angle markers tell us which angles are congruent

  • angle M = angle R  (single arc)
  • angle N = angle S (90 degree angle marker)
  • angle P = angle T (double arc)

That concludes the second part of choice A.
