Formula for area of a triangle :

Area (triangle) = 1/2 × base × height

=============================================================

Solving :

Triangle 1 (Top Left)

⇒ Area = 1/2 × 11 × 3

⇒ Area = 33/2

⇒ Area = 16.5 in²

Triangle 2 (Top Right)

⇒ Area = 1/2 × 8 × 7.2

⇒ Area = 4 × 7.2

⇒ Area = 28.8 cm²

Triangle 3 (Bottom Left)

⇒ Area = 1/2 × (5.5 + 5) × 10.4

⇒ Area = 10.5 × 10.4

⇒ Area = 109.2 m²

Triangle 4 (Bottom Right)

⇒ Area = 1/2 × (2 + 7) × 5.5

⇒ Area = 9 × 2.75

⇒ Area = 24.75 in²

On a certain airline, customers are assigned a row number when they purchase their ticket, but the four seats within the row are

maksim [4K]

Answer:

The probability that they sit next to each other is 50%.

Step-by-step explanation:

Consider the provided information.

It is given that there are four seats within the row are first come, first served during boarding.

There are 4 seats and 2 customers (Karen and Georgia)

The total number of ways in which Karen and Georgia can sit is: $^4C_2$

Now if they will sit together, then consider Karen and Georgia as a single unit.

Thus, the number of ways in which they can sit together is: $^3C_1$

The required probability is:

$P=\frac{^3C_1}{^4C_2} \\\\P=\frac{3}{6}\\\\P=\frac{1}{2}$

Hence, the probability that they sit next to each other is 50%.

The first gardener can finish the job in 6 hours, and the second gardener can do the same job in 7 hours. How long it will take

marissa [1.9K]

If the first gardener can finish the job in 6 hours, it means that every hour he completes 1/6 of the job.

By the same logic, the second gardener completes 1/7 of the job per hour.

So, if they work together, they complete

$\dfrac{1}{6}+\dfrac{1}{7}=\dfrac{7+6}{42}=\dfrac{13}{42}$

of the job per hour.

So, after 42/13 of a hour, they'll complete the job. Since one hour is made of 60 minutes, 42/13 of a hour is

$\dfrac{42}{13}\cdot 60 \approx 194$

So, it will take them about 194 minutes to finish the job, i.e. about 3 hours and 14 minutes.
