Answer:

<em>The sale price of the washing machine is £207.50.</em>

Step-by-step explanation:

<u>Percentages </u>

To find a percentage of a given number, the procedure is multiplying the percentage by the number and divide by 100.

Suppose the normal price of the washing machine was x before the discount. The discount is:

17% of x = 17/100 * x = 0.17x

This discount is given as £42.50, thus:

0.17x = £42.50

Solving:

x = £42.50/0.17

x = £250

The sale price is:

£250 - £42.50 = £207.50

The sale price of the washing machine is £207.50.

Explain how to find coordinates for Q

Vesna [10]

Answer:

Q = (4, - 1)

Step-by-step explanation:

DF is the diameter of the circle with center Q.

So, Q is the midpoint of DF.

By mid point formula.

$Q = \bigg( \frac{1 + 7}{2}, \: \: \frac{3 - 5}{2} \bigg) \\ \\ Q = \bigg( \frac{8}{2}, \: \: \frac{ - 2}{2} \bigg) \\ \\ Q = (4, \: \: - 1)$

How to evaluate the expression

noname [10]

$[(-72) \div (-2)]^3 - (-7) \times (-10)$

$= [36]^3 - (-7) \times (-10)$

$=46656 - (-7) \times (-10)$

$=46656 - (70)$

$=46586$

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

$2^3 - 9 \times (2 - 4)$

$= 8 - 9 \times (-2)$

$= 8 - (-18)$

$= 8 + 18$

$= 26$

$2.50 was left for each person.

4(9.50) + x = 48

38 + x = 48

subtract 38 on both sides

x = 10

10$ was left in total by all 4 people

10/4 = 2.50

$2.50 was left over for each person

A credit union client deposits $3,300 in an account earning 6.5% interest, compounded annually. What will the balance of the acc

astra-53 [7]

Answer:

The balance of account at the end of 36 years is $31,849.29

Step-by-step explanation:

We are given the following in the question:

P = $3,300

r = 6.5% = 0.065

t = 36 years

The compound interest is given by:

$A = p\bigg(1+\dfrac{r}{n}\bigg)^{nt}$

where A is the amount, p is the principal, r is the interest rate, t is the time in years and n is the nature of compound interest.

Since interest is compounded annualy we use n = 1

$A = 3300\bigg(1+\dfrac{0.065}{1}\bigg)^{36}\\\\A = \$31,849.29$

Thus, balance of account at the end of 36 years is $31,849.29
