Answer:

Option (2)

Step-by-step explanation:

By applying tangent rule in the given right triangle,

tan(42°) = $\frac{\text{Opposite side}}{\text{Adjacent side}}$

tan(42°) = $\frac{6}{\text{Width}}$

Width = $\frac{6}{\text{tan}(42)}$

Width = 6.67

Therefore, width of the given triangle is 6.67 units.

Option (2) is the correct option.

Which one is bigger 2/3 or 4/7

Brut [27]

Answer:

$\frac{2}{3}$

Step-by-step explanation:

To compare the fractions we require them to have a common denominator.

The lowest common multiple of 3 and 7 is 21

Change both fractions into fractions with a denominator of 21

$\frac{2(7)}{3(7)}$ and $\frac{4(3)}{7(3)}$

= $\frac{14}{21}$ and $\frac{12}{21}$

The numerator 14 is greater than 12, hence

$\frac{2}{3}$ is the larger fraction

tresset_1 [31]

Answer:

$6250

Step-by-step explanation:

Hello!

First, we find out how much you spend a week.

Since you buy a $5 coffee 5 days a week we multiply the price for a coffee by 5.

5 * 5 = 25.

Next, we find out how much you spend a year.

Since you do it 50 weeks a year we multiply the amount you spend a week by 50

25 * 50 = 1250

Then, we find out how much you spend in 5 years.

We multiply the cost a year by the amount of years

1250 * 5 = 6250

The answer is $6250

Hope this helps!
