What is Simple interest?A quick and easy method of calculating the interest charge on a loan is called a Simple interest.
Given that;
Louis invested £2950 in a savings account for 5 years.
He was paid 1.9% per annum compound interest for each of the first 4 years.
And, He was then paid R% interest for the fifth year.
Louis had £3257 in his savings account at the end of the 5 years.
Here, We know that;
⇒ Compound interest formula = Capital × (1 + r%) ⁿ
Where, n is time in years.
So, We can formulate;
⇒ £2950 × (1 + 0.019)⁴
⇒ £3180.67
And, For calculate R;
⇒ £3180.67 × (1 + R%)⁵ = £3257
⇒ R = 2.4%

In a fruit punch you mix 150 ml of lemonade with 250 ml of fruit juice. Write the ratio of the volume of lemonade to the volume of fruit juice. Give your ratio in its simplest form.
Answers
Answer:the ratio of the volume of lemonade to the volume of fruit juice in simplest form = 3:5
Step-by-step explanation:
Volume of lemonade in the mixture = 150ml
Volume of fruit juice in the mixture = 250ml
Ratio of the volume of lemonade to the volume of fruit juice= 150ml: 250ml
and reducing to the simplest form , we have
150:250
dividing both by 10 gives
15:25
dividing both by 5 gives
3:5
Therefore the ratio of the volume of lemonade to the volume of fruit juice in simplest form = 3:5

Written as a simplified polynomial in standard form, what is the result when
(x - 2)^2is subtracted from 9x^2-8x?
Answers
Answer:
9x^2 - 10x -4
Step-by-step explanation:
It is set up like this
9x^2 - 8x
- (x-2)2
First solve (x-2)2
the answer is (2x-4)
so now you can do this instead
9x^2 - 8x
- 2x - 4
----------------------------------
9x^2 - 10x +4
9x^2 minus zero is 9x^2
-8x-2x is -10x
0- -4 is 4 because that is like saying 0 + 4 because double negatives equal a positive
A simpler way is to change all the numbers to the opposite sign and then change the minus to a plus
like this
9x^2 - 8x
+ -2x + 4
----------------------------------
9x^2 - 10x +4

A clothing manufacturer produces 120 garments per hour, of which 5 are damaged. How many garments without damage would the manufacture except to produce in 8 hours?
Answers
Answer:
Step-by-step explanation:First we have to found all the clothes that the manufacturer produces in 8 hours,
As given 120 clothes = produce in 1 hour
X clothes = produce in 8 hour
By cross multiplication, we get
X= 120*8
X= 960 total clothes produced in 8 hours
As also given that in each hour 5 clothes damaged ,so we can write as
5 clothes = damaged in 1 hour
Y clothes = Damaged in 8 hour
By cross multiplication we get
Y= 40 clothes damaged in 8 hour
So the total clothes that manufacturer produce with out damage clothe will be ,
Total normal clothes = X-Y = 960 - 40 = 920 clothes

Maria and Don had $20,800 in medical expenses. Their family medical insurance covered 60% of these expenses. The IRS allows medical and dental expense deductions for the amount that exceeds 10% of a taxpayer's adjusted gross income. If their adjusted gross income is $101,598, how much can they claim as a medical deduction? Fill in the blank 1 Next
Answers
Maria and Don has claimed $1839.8 as a medical deduction.
Calculate medical expenses after removing medical insurance expense, that is
20,800 - 60% of 20,800
= 12480
Now, 20,800-12480
=$8,320
Now calculate 10% of gross income
10% of 101,598
= 10/100 × 101,598
= 0.1 × 101,598
= $10,159.8
Now medical deduction = 10% of income - Medical expenses
= 10,159.8-8,320
= $1839.8
Therefore, the medical deduction is $1839.8.

Heather finished the 12-kilometer race in 2 hours. If Heather kept her pace constant, what was her rate? A. 24 km/hr. B. 14 km/hr. C. 10 km/hr. D. 6 km/hr.
Answers
Answer: D, 6km/hr.
Step-by-step explanation:
Heather can finish a 12-kilometer race in 2 hours, and now we have to find how many kilometers she can ride/run at in 1 hour.
How many hours can Heather run in 1 hour? To solve that, we can use the equation 12 ÷ 2.
12 ÷ 2 = 6.
Therefore, if Heather keeps her pace constant, then her rate will be 6km/hr, or D.
