Practice YOU CAN DRAW ON THE GRAPH FOR THIS QUESTION Here is a speed-time graph for a train (a) Work out an estimate for the distance the train travelled in the first 20 seconds. Use 4 strips of equal width (b) Is your answer to (a) an underestimate or an overestimate of the actual distance the train travelled? Give a reason for your answer. (c) By drawing a suitable tangent, find an estimate of the gradient to the curve at t=15. Give the units of your answer. 25 20 15 Speed (m/s) 10 15 20 25 0 10 Time (5) pint RIA 31 on the

step-by-step explanation:

total amount to be paid = $19.5

step-by-step explanation:

given ,

original price = $25.99

discount = 25%

discount amount = 25% of original price

discount amount = 25/100   * 25.99

discount amount = $6.49

hence , the total amount to be paid = original price - discount amount

                                                            = $25.99 - $6.49

                                                            =$19.5

total amount to be paid = $19.5

30.5*10=350$

you have to multiply the number without the decimal point then add it later but if its tenn u must move the place value of the decimal point 1 to the right.

we can't see all full 4 options, but if this is the full option, than the very left one is correct:

-2/5 * -3 3/4

remake the question, adding a picture of all the question, or write down the full left and right answers.
