Brian invests £1300 into his bank account. He receives 10% per year simple interest.

How much will Brian have after 3 years?

Give your answer to the nearest penny where appropriate.

Answers

Answer 1
Answer:

Answer:

£1690

Step-by-step explanation:

Amount invested by Brian = £1300

rate of simple interest = 10%

To find money Brian will have after three years

He will have amount invested in bank and interest earned in three years from that amount.

Simple interest for any principal amount p is given by

SI = P*R * T /100

where SI  is simple interest earned

T is time period for which simple interest is earned

R is rate of interest

Substituting value of P , R and T we have

SI = 1300*10* 3 /100 = 390

Therefor interest earned will be £390

Total money with Brian after three years = principal amount invested + interest earned in 3 years

= £1300 + £390 = £1690

The requried solution for each percentage is
1.  350 is 70% of 500          2. 37.5% of 64 is 24
3. 40% of 6.50 is 2.60         4. 20 of 140 is 28.

What is the percentage?

The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.

Here,
We have to determine a number, whose 70% is 350
Let eh number x,

According to the question,
70% of x = 350
x = 350/ 70%
x = 350/0.70
x = 500

Similarly,
37.5% of 64 is 24
40% of 6.50 is 2.60
20 of 140 is 28.

Thus, the requried solution for each percentage is shown above.

learn this , it will help u with all of these percent problems.
percent formula : is/of = %/100

350 is 70% of what number....
is = 350
% = 70
of = x
now sub
350/x = 70/100
cross multiply
70x = 35000
x = 35000/70
x = 509....so 350 is 70% of 500.
=====================
is/of = %/100

what percent of 64 is 24...
% = x
is = 24
of = 64
now sub
24/64 = x/100
cross multiply
64x = 2400
x = 2400/64
x = 37.5..so 37.5% of 64 is 24
====================
u get the idea....
the last 2 answers are : 40% and 28

3÷0.1=30Choose all of the statements that explain how the quotient relates to the dividend.
Dividing 3 by 0.1 tells how many tenths are in 3 ones.

3÷0.1 is the same as 30÷1, which is 30.

It takes 10 tenths to make 1 whole, so it will take 3 times 10 tenths to make 3 wholes. 3×10=30.

The quotient has 110 of the value of the dividend so the dividend must be 10 times greater.

The 3 in 30 is 1 place to the right of the 3 in the whole number 3 which increases the value of the number 10 times.

BRAINLIEST ANSWER!!What is the median of the data represented by the box plot?



Enter your answer in the box.

Answers

The median is 20 because this is the middle vertical line of the box and whisker plot (aka box plot). The median line doesn't have to be in the direct center of the box. It just has to be between the edges of the box. The left edge is Q1 and the right edge is Q3. 

Answer: The answer is 20

Step-by-step explanation:

If you count all the numbers shown in the question: 0, 12.5 ,20 65 And 145.75

You have 5 numbers all together,

Tip: Look for the key word, such as the key word in this question is ''Median''

The word Median stands for ''The median is the middle number in a sorted, ascending or descending, list of numbers and can be more descriptive of that data set than the average.''

This means that the number 20 is the correct answer because, They are two numbers behind the number 20 being 0 and 12.5. And there's two numbers in front of the number 20 being 65 and 143.75

Hi Brainiac


x+y=3

3x+3y=15

We need to solve for x+y=3 for x

So let's start by adding -y to both sides

x+y-y=3-y

x= -y+3

Now we need to substitute -y+3 for x in 3x+3y=15

3x+3y=15

3(-y+3)+3=15

9=15

Next, add -9

9-9 = 15-9

0=6
