Alex invests £4000 for 7 years.

Mathematics
1 answer:
icang [17]3 years ago
8 0

Answer:

Step-by-step explanation:

Use the equation

A(t)=P(1+r)^t and fill it in using the info we were given:

5263.73=4000(1+r)^7 Begin by dividing both sides by 4000 to get

1.3159325=(1+r)^7 and take the 7th root of both sides to "undo" that 7th power on the right. Doing that gives us

1.04 = 1 + r so

.04 = r and the interest rate is 4%

multiplying both sides by x^2
28=\frac{7x^2}{xy}

Lunna [17]

Answer:

80x

Step-by-step explanation:

If you pay 80 a month then to find the total you have paid after any number of months you would multiply amount times time which in this case is 80

a constant is the a number on its own so in this case there would be none

a coefficient is the number in front of a variable. Since the equation is 80x the coefficient is 80

Sam and Bethan share £54 in the ratio of 5:4 work out how much each gets
Sindrei [870]
Answer:
Sam gets £30 and Bethan gets £24.
Why?
When dealing with ratios, add up the numbers in the ratio.
5 + 4 = 9
Now, divide the total amount of money by that number.
£54/9 = 6
Now you have the base rate. Multiply each quantity in the ratio by this number.
5*6 = 30
4*6 = 24
Now, the ratio is (in euro) 30:24. This means that Sam has £30 and Bethan has £24.
Check:
30 + 24 = 54
