Four brothers and their sister have the average age 7. Four brothers have the average age 6. How old is the sister?
AnnyKZ [126]

Answer:

11 years old

Step-by-step explanation:

If four brothers have the average age 6, then the sum of their ages is

4\cdot 6=24

years.

Let x years be the age of sister. If four brothers and their sister have the average age 7, then

\dfrac{24+x}{5}=7.

Multiply this equation by 5:

24+x=35\Rightarrow x=35-24=11.

The sister is 11 years old.

Can someone please help me ASAP​
deff fn [24]

Answer:

QR = 17 cm

Step-by-step explanation:

Δ RST is a 5- 12- 13 triangle with hypotenuse RT = 13 cm , then

TS = 5 cm and PT = 2 × 5 = 10 cm

So PS = 10 + 5 = 15 cm

PS is parallel to the vertical line from vertex Q and intersects the horizontal line projected from SR of length 20 - 12 = 8 cm

Using the right triangle formed calculate QR using Pythagoras' identity

QR² = 15² + 8² = 225 + 64 = 289 ( take square root of both sides )

QR = \sqrt{289} = 17
