Answer:

x = 14°

Step-by-step explanation:

The triangle's interior angle at C is the supplement of the exterior angle marked 124°.

C = 180° -124° = 56°

The exterior angle at B is the sum of the remote interior angles:

6x = 56° +2x

4x = 56° . . . . . . subtract 2x

x = 14° . . . . . . . . divide by 4

This year, a company produced 8 percent more items than last year. If the company produced 243 items this year, how many items d

Ilya [14]

Answer:

Last year company produce 225 items

Step-by-step explanation:

let the number of items produced last year be x

Here we are asked to find the percent increase in the production of the items from last year

The production for the last year = x

The production for the current year = 243

Total increased production =243-x

Hence percentage calculation = $\frac{\increase \in \sale}{\last \year \sale} \times 100$ %

Increased percentage = $\frac{243-x}{x} \times 100$ %

Percentage increased = 8 %

Hence

$\frac{243-x}{x} \times 100 = 8$

${243-x}\times 100 = 8 \times x$

$24300-100x = 8x$

$24300=100x+8x$

$24300=108x$

$x= \frac{24300}{108}$

x=225

Hence Last year production was 225 items

a) If the price of a train ticket from New York to Washington DC rose by the rate of inflation between 1995 and 2016, how much w

Alla [95]

Answer:

$ 99.60

Step-by-step explanation:

Thinking process:

According to financial data, the inflation rate in 1995 was at 2.5 %.

In 2016, the inflation rate was at 2.1 %

The difference was: 2.1 - 2.5 = -0.4 %

The price in 2016 = Original price - Adjusted price

Adjusted price = $0.004* ($ 100) = $ 0.4$

The new price will be $$ 100 - $ 0.4\\= $ 99.60$

The new price will be $ 99.60
