Answer:
Rebecca is incorrect. The equivalent quarterly interest rate is 1.75%.
Explanation:
The formula for compound interest is i = r/n.
r represents the interest rate in decimal form.
n represents the compounding periods in a year.
Calculate the interest rate for 7% compounded quarterly:
Since interest compounded quarterly is four times a year, n = 4.
7% is converted to decimal form by dividing by 100.
7 / 100 = 0.07
r = 0.07
Substitute these into the formula:
i = r/n
= 0.07/4
= 0.0175
0.0175 is in decimal form. To convert it to a percentage, multiply it by 100.
0.0175 X 100 = 1.75%
1.75% ≠ 2%
Therefore, Rebecca is incorrect. The equivalent quarterly interest rate is 1.75%.
Answer: I think the answer is b
Step-by-step explanation:
20% off means that there is 80% on which means you pay that 80% so you move the decimal point two spots
80.0% to .80 and multiply store a’s price of 59.99 to get 47.992 round the two in the decimal down making the total price for store a 47.99 and total price for store b 49.99 so store a is the better price by two dollars
Answer:
2.44 miles
Step-by-step explanation:
Give the following :
Average miles to school = 12 miles per hour
Average Miles from school = 15 miles per hour
Total ride time : ( time to school + time from school) = 22 minutes = (22/60) = 0.3667
Recall:
Speed = distance / Time
Time = distance / speed
Let distance = d
For the scenario described :
d/12 + d/15 = 0.3667
(5d + 4d) / 60 = 0.3667
5d + 4d = 22
9d = 22
d = 22/9
d = 2.44 miles
Answer:
c=29°
Step-by-step explanation:
angle b=97°{ vertically opposite angle}
now,
97°+54°+c=180°{ sum of angle of triangle}

So this problem is asking you to plug numbers in for t. 0 1 2 3 4 5. So your first equation would be 2× 0+8 and you would get 8 so for 0 toppings you would pay 8 dollars then graph this over 0 up 8. Next equation 2×1+8 is 10. Graph. over 1 up 10. Next 2×2+8 is 12. Graph. Over 2 up 12. next 2× 3 + 8 is 14. Graph. Over 3 up 14. Next 2×4+8 is 16 so over 4 up 16. Last 2×5+8 is 18 so over 5 up 18. Your Y-intercept is the dot that is on the y axis and in this problem that is 8. This means if you buy 0 toppings you will spend 8 dollars.
