Mathematics
1 answer:
tatuchka [14]3 years ago
6 0

Answer:

£121

Step-by-step explanation:

5/12 of the total coins = 5/12 x 96 = 40   ⇒   40 coins are £2 coins

26 of the coins are £1 coins

Number of 50p coins = 96 - 40 - 26 = 30  ⇒  30 of the coins are 50p coins

Total money collected = 40 x £2 + 26 x £1 + 30 x £0.50 = £121

(rememberinf to convert 50p into £s)

In a class there are 25 students 15 are boys what percentage are girls​
tankabanditka [31]

Answer:

40%

Step-by-step explanation:

Total students = 25

Boys = 15

Girls = 25 - 15 = 10

Percent of girls = 10/25

Percent is out of 100.

=> 10/25 = x/100

=> Cross multiply

=> 25 * x = 100 * 10

=> 25x = 1000

=> 25x/25 = 1000/25

=> x = 40

So, 40% are girls

What constant term should be added to both sides to complete the square on the left side?
grandymaker [24]

Answer:

  • 9/64

Step-by-step explanation:

<u>Given</u>

  • x² - 3/4x + _____ = 10

Need to complete square on the left side of equation

<u>The square should be in the form of:</u>

  • (a + b)² = a² + 2ab + b²

<u>We see a = x therefore </u>

  • 2b = -3/4, so
  • b = -3/8 and
  • b² = (-3/8)² = 9/64

So the missing constant term is 9/64

Suppose you'd like to save enough money to pay cash for your next car. The goal is to save an extra $28,000 over the next 6 year
Anna35 [415]

Given:

• Amount to save, A = $28,000

,

• Time, t = 6 years

,

• Interest rate, r = 5.3% ==> 0.053

,

• Number of times compounded = quarterly = 4 times

Let's find the amount that must be deposited into the account quarterly.

Apply the formula:

FV=P(\frac{(1+\frac{r}{n})^{nt}-1}{\frac{r}{n}})

Where:

FV is the future value = $28,000

r = 0.053

n = 4

t = 6 years

Thus, we have:

28000=P(\frac{(1+\frac{0.053}{4})^{4\times6}-1)}{\frac{0.053}{4}}

Let's solve for P.

We have:

\begin{gathered} 28000=P(\frac{(1+0.01325)^{24}-1}{0.01325}) \\  \\ 28000=P(\frac{(1.01325)^{24}-1)^{}}{0.01325}) \\  \\ 28000=P(\frac{1.371509114-1}{0.01325}) \\  \\ 28000=P(\frac{0.371509114}{0.01325}) \end{gathered}

Solving further:

28000=P(28.0384237)

Divide both sides by 28.0384237:

\begin{gathered} \frac{28000}{28.0384237}=\frac{P(28.0384237)}{28.0384237} \\  \\ 998.6=P \\  \\ P=998.6 \end{gathered}

Therefore, the amount that must be deposited quarterly into the account is $998.60

ANSWER:

$998.60

$56 they are 25% off wants to know what is the discount price
iVinArrow [24]

Answer:

$42

Step-by-step explanation:

This is an example of a percentage decrease.

To work out the percentage decrease you would first need to convert the percentage of 25% into a decimal. You can do this by dividing the percentage  of 25 by 100, this gives you 0.25. This is because percentages are out of 100.

The next step is to minus 0.25 from 1, this gives you 0.75. This is because we are working out the percentage decrease.

To work out the discounted price you would multiply the amount of $56 by 0.75, this gives you $42.

1) Divide 25 by 100.

25/100=0.25

2) Minus 0.25 from 1.

1-0.25=0.75

3) Multiply $56 by 0.75.

56*0.75=42
