Evaluating an expression consists of just replacing the letter by its value and do the calculus.
We have the expression 14b - 513. And by hypothesis, b = 44.
So just replace b by 44.

14b - 513 = 14*44 - 513 = 616 - 513 = 103.

So 14b - 513 = 103 (answer b) when b = 44.

Hope this helps! :)

Paul drove 225 miles to visit his parents. The graph below shows the distance traveled and the total time of the trip. Write and
ziro4ka [17]

50mph

Step-by-step explanation:

The image of the motion of Paul's derive is attached already.

From the line graph we can obtain a lot of information that will help us unravel the average speed of Paul within the given time frame.

What is average speed?

 Average speed is the rate of change of total distance covered with time taken .

Average speed = \frac{total distance }{time}

To find the total distance covered;

 Distance at time 1 = 75miles

  Distance at time 4 = 225miles

Distance covered between 1 - 4 = 225 - 75 = 150miles

Time taken for the journey = 4 - 1 = 3hrs

Input the values in the equation;

   Average speed = \frac{150}{3} = 50mph

If the length of AC equals 18, what is the length of the midsection DE
Free_Kalibri [48]

Answer:

The length of the midsegment is 9 ⇒ (B)

Step-by-step explanation:

In a triangle,

  • The midsegment is the segment which joining the midpoints of two opposite sides of it
  • The length of the midsegment is half the length of the third side in the triangle which opposite to it

<em>Let us use this rule to solve our question</em>

In Δ AC

∵ DE is the midsegment of it

∵ DE is opposite to the side AC

∴ The length of DE = 1/2 the length of AC

∵ The length of AC = 18

∴ The length of DE = 1/2 × 18

∴ The length of DE = 9

∴ The length of the midsegment is 9

The correct answer is B

Which fraction has a terminating decimal as its decimal expansion?
alex41 [277]
'One third' as a decimal is 1 ÷ 3 = 0.333333..... ⇒ The decimal is recurring

'One fifth' as decimal is 1 ÷ 5 = 0.2 ⇒ The decimal terminates at the tenth value

'One seventh'  as decimal 1 ÷ 7 = 0.142857142857.... ⇒ The decimal is recurring for every digit between 1 and 7

'One ninth' as decimal 1 ÷ 9 = 0.111111.... ⇒ The decimal is recurring
