I NEED THE ANSWER FOR THIS QUESTION ASAP PLEASE EXPLAIN THE STEP BY STEP I NEED TO SHOW WORK
Svetradugi [14.3K]

Answer:

45 3/10 miles per hour

Step-by-step explanation:

Distance travelled by the car = 30 1/5 miles

Time taken = 2/3 of an hour

Average speed = distance travelled / time taken

= 30 1/5 miles ÷ 2/3 of an hour

= 151/5 ÷ 2/3

= 151/5 × 3/2

= (151 * 3) / (5 * 2)

= 453 / 10

= 45 3/10 miles per hour

Average speed = 45 3/10 miles per hour

Annie invests £9500 for 5 years in a savings account. She gets 1.8% per annum compound interest. How much money does Annie have
Trava [24]

Answer:

£10386.34

Step-by-step explanation:

The amount in an account for a principal P saved at compound interest for a period of n years at an annual rate of r% is calculated using the formula:

A(n)=P(1+r)^n

In this case:

Principal, P=£9500

r=1.8%=0.018

n=5 years

Therefore:

A(5)=9500(1+0.018)^5\\=9500(1.018)^5\\=\£10386.34

At the end of 5 years, Annie will have £10386.34
