A bank offers 2% simple interest per year. A woman opens an account with deposit of 900 pounds. She closes the account 2 years later. How much will she withdraw.

Answers

simple interest formulae = PRT/100

where

p stands for percentage (2%)

r stands for rate ( 900)

t stands for time (2 years )

2×900×2/100

=3600/100

=36

Deposit interest

Level : SHS Keyword : deposit interest, simple interest

Deposit Interest in 2 years

= D × i × T/365 days

= 900 pounds × 2% × (365 × 2 years)/365 days

= 900 pounds × 0.02 × 730 days/465 days

= 900 pounds × 0.02 × 2

= 36 pounds

Her Deposit in 2 years

= 900 pounds + 36 pounds

= 936 pounds

So, her deposit if she will withdraw is 936 pounds

Answers

Answer:

5924, 51

Step-by-step explanation:

X = 4200(1.035)^10

And put it in a calculator

The total value of the account after 10 years is $5,924.52.

Given that,

The deposited amount is $4,200.The rate of interest is 3.5%.And, the time period is 10 years.

Based on the above information, the calculation is as follows:

[tex]= \$4,200 \times (1 + 3.5\%)^{10}[/tex]

= $5,924.52

Therefore we can conclude that the total value of the account after 10 years is $5,924.52.

The price of an item yesterday was $130. Today, the price rose to $299. Find the percentage increase.

Answers

Answer:

130%

Step-by-step explanation:

Use the formula for percent change: difference = % * original price

To find the difference, you have to do 299 - 130, which is 169.

The original price is $130 because this is the price before it rose to $299.

Now, you have the equation 169 = % * 130.

We don’t know the percentage right? No, so we have to find the percentage by dividing 169 by 130, which gives you 1.3. Lastly turn 1.3 into a percentage by multiplying 1.3 by 100, and 1.3 as a percentage is 130%. So therefore, the percent increase is 130%.

130%

Step-by-step explanation:

Yesterday = $130.

Today = $299 .

((final price - initial price)/(initial price)) × 100%

= (($299 - $130)/$130) × 100%

= ($169/$130) × 100%

= $1,3 × 100%

= 1,3 × 100%

= 130%

The other person didn’t give x and y so I will:
5x + 2 = 12. This is because if we rotate the quadrilateral those two are equivalent.
Minus 2 from both sides
5x = 10
Divide by 5
X=2

5y+6 = 111
Minus 6 from both sides
5y = 105
Divide by 5 from both sides

The function g(x) represents the number of bread loaves Sonia bakes per hour, where x is the number of hours she works. Show all work to find f(g(x)), and explain what f(g(x)) represents.
f(x) = 8^2 +4
g of x equals the square root of the quantity 2 x cubed

Answers

Answer:

[tex] f(x)=8x^2+4\\ g(x)=\sqrt{2x^3}\\ f(g(x))=8((\sqrt{2x^3})^2)+4\\=16x^3+4\\=4(4x^3+1)[/tex]

The function f(g(x)) will be f(g(x)) = 4(4x³ + 1) where 'x' is the number of hours.

What is a function?

A function is an assertion, concept, or principle that establishes an association between two variables. Functions may be found throughout mathematics and are essential for the development of significant links.

The functions are given below.

f(x) = 8x² + 4

g(x) = √(2x³)

The function f(g(x)) is calculated as,

f(g(x)) = 8[√(2x³)]² + 4

f(g(x)) = 8[√(2x³)]² + 4

f(g(x)) = 16x³ + 4

f(g(x)) = 4(4x³ + 1)

The function f(g(x)) will be f(g(x)) = 4(4x³ + 1) where 'x' is the number of hours.

“To find 623, I can just take the value of 613 then either multiply it by 12 or divide it by 2.” Do you agree with her? Explain why or why not.

Answers

Step-by-step explanation:

613 and 623 are very close values.

multiplying by 12 or a division by 2 changes the starting value drastically.

so, this cannot be right.

and dividing 613 by 2 also makes it even smaller. but to get 623 we need to make it bigger.

so, therefore, even without actually calculating the numbers, the statement is proven false.

Sarah and Emily ran a 324m race. If Sarah ran it in 61.3 seconds and Emily ran it in 60.4 seconds, how much faster was Emily than Sarah? Round to the nearest hundredth and give your answer in meters per second.

Answers

Answer:  0.08 meters per second

=======================================================

Work Shown:

Distance = rate*time

rate = distance/time

----------------

For Sarah, she runs 324 m in 61.3 seconds. Her speed is:

rate = distance/time

rate = (324 m)/(61.3 sec)

rate = (324/61.3) meters per second

rate = 5.28548 meters per second approximately

----------------

Repeat the same set of steps for Emily

rate = distance/time

rate = (324 m)/(60.4 sec)

rate = (324/60.4) meters per second

rate = 5.36423 meters per second approximately

----------------

The last thing to do is subtract the results we got

5.36423 - 5.28548 = 0.07875

This then rounds to 0.08 meters per second when rounding to two decimal places.
