Answer:

£ 38,110

Step-by-step explanation:

We need to find salary for 1 year (12 months).

  • Monthly Salary = 1410, so yearly would be:

1410 * 12 = 16,920

  • 26% of total profit. Let's find the profit first:

Profit is Income - Cost

So, that would be (from table):

Profit = 549000 - 473500 = 75,500

26% of that would be:

26/100 = 0.26

0.26 * 75,500 = 19,630

  • 390 bonus for each month she sells atleast 16 cars

Out of 12 months (1 year), she sold at least 16 cars in 4 months, so she gets bonus of 390 for those 4 months, that would make:

390 * 4 = 1560

Total Pay for the year would be summation of all these:

Total Pay = 16,920 + 19,630 + 1560 = £ 38,110

Line n intersects lines 1 and m, forming the angles shown in the diagram below.
bija089 [108]

Answer:

B. 4.5

Step-by-step explanation:

(6x + 42)° and (18x - 12)° are alternate interior angles. If line l is parallel to line m, therefore,

6x + 42 = 18x - 12

Solve for the value of x. Combine like terms.

6x - 18x = -42 - 12

-12x = -54

Divide both sides by -12

-12x/-12 = -54/-12

x = 4.5

Therefore, x = 4.5 would prove lines l and m are parallel to each other.

-1/4d-2/5d=39 <br> Solve for d <br> Please explain I don’t understand
Papessa [141]

Given:

The equation is

-\dfrac{1}{4}d-\dfrac{2}{5}d=39

To find:

The value of d.

Solution:

We have,

-\dfrac{1}{4}d-\dfrac{2}{5}d=39

Taking LCM, we get

\dfrac{-5d-8d}{20}=39

\dfrac{-13d}{20}=39

Multiply both sides by 20.

-13d=39\times 20

Divide both sides by -13.

d=\dfrac{39\times 20}{-13}

d=-3\times 20

d=-60

Therefore, the value of d is -60.
