Given the information in the photo:

  • The height: 3/4 in
  • The length : 3/4 in
  • The width : 3/4 in

The volume of this solid using the formula

V=Bh where:

  • h is the height
  • B is the area of the base = The length * The width

=> The volume of this solid is:

V = 3/4 * 3/4 * 3/4

<=> V = 27/64 cubic inches

The sum of two consecutive integers is 123 what’s is the smallest of the two integers
RideAnS [48]

The smallest of two integers is 61

Step-by-step explanation:

Let x be the smaller integer

Then the next integer will be:

x+1

According to given statement that the sum of both is 123

x+ (x+1) = 123\\x+x+1=123\\2x+1=123

Subtracting 1 from both sides

2x+1-1=123-1\\2x=122

Dividing both sides by 2

\frac{2x}{2}=\frac{122}{2}\\x=61

The smallest of two integers is 61

F the point T is between the points B and N, then which of the following is true?
valentina_108 [34]
Assuming T, B and N are all on the same line, then we can say

BT + TN = BN

which is the segment addition postulate. 

Subtract TN from both sides to get
BT + TN = BN
BT + TN - TN = BN - TN
BT = BN - TN
BN - TN = BT

Which is what choice C is saying. Therefore the answer is choice C.
