Answer:
Step-by-step explanation:
The formula for the accrued amount from compound interest is
1. Amount in account on 1 Jan 2015
(a) Data:
a = £23 517.60
r = 2.5 %
n = 1
t = 1 yr
(b) Calculations:
r = 0.025
The amount that gathered interest was £22 944.00 but, before the interest started accruing, Carol had withdrawn £1000 from the account.
She must have had £23 944 in her account on 1 Jan 2015.
(2) Amount originally invested
(a) Data
A = £23 944.00
3. Summary
1 Jan 2014 P = £23 360.00
1 Jan 2015 A = 23 944.00
Withdrawal = <u> -1 000.00
</u>
P = 22 944.00
1 Jan 2016 A = £23 517.60
Answer:
(5x+1)(x+7)
Step-by-step explanation:
4x^2+26x+6+x^2+10x
5x^2+36x+7
(5x+1)(x+7)
Prove
5x*x + 5x*7 + 1*x + 1*7
= 5x^2 + 35x + x + 7
= 5x^2 + 36x + 7
Answer:
f
Step-by-step explanation:
Green vines attached to the trunk of the tree had wound themselves toward the top of the canopy. Ants used the vine as their private highway, avoiding all the creases and crags of the bark, to freely move at top speed from top to bottom or bottom to top depending on their current chore. At least this was the way it was supposed to be. Something had damaged the vine overnight halfway up the tree leaving a gap in the once pristine ant highway.
Answer:
Dot plot, because a small number of scores are reported individually.
Step-by-step explanation:
Histogram is usually used when a group of data to be represented is usually large and given in ranges or intervals.
However, for a data set, such as the scores of the group of 12 students who participated in a dance competition are reported individually, and not as ranges or intervals, a dot plot would best for representing this small number of scores.
See attachment below to see how we can easily represent the given scores of the students on a dot plot. Each dot represents a score value for each student.
Answer:
17 and 38
Step-by-step explanation:
x + y = 55......x = 55 - y
x * y = 646
y(55 - y) = 646
55y - y^2 = 646
y^2 - 55y + 646 = 0
(y - 17)(y - 38) = 0
y - 17 = 0 y - 38 = 0
y = 17 y = 38
ur numbers are 17 and 38
