In a competition, the ratio of the number of tickets Mark collected to the number of tickets Julia collected is 4:3. Julia colle

Afina-wow [57]

Answer: 84 tickets

Step-by-step explanation:

We are told the ratio of the number of tickets Mark collected to the number of tickets Julia collected is 4:3

$\frac{M}{J}=\frac{4}{3}$ (1)

In addition, we are told Julia collected 36 tickets:

$J=36$ (2)

Substituting (2) in (1):

$\frac{M}{36}=\frac{4}{3}$ (3)

Isolating $M$ :

$M=48$ (4)

Adding Mark's tickets to Julia's:

$M+J=48+36=84$

Therefore, both collected 84 tickets.

What is the length of leg y of the right triangle? 84 85 O1 09 O 13 O 26

Softa [21]

Answer:

$\boxed{\sf Length \ of \ leg \ y = 13}$

Step-by-step explanation:

Pythagoras theorem states that “In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides”.

$\therefore \\ \sf \implies {84}^{2} + {y}^{2} = {85}^{2} \\ \\ \sf {84}^{2} = 7056 : \\ \sf \implies 7056 + {y}^{2} = {85}^{2} \\ \\ \sf {85}^{2} = 7225 : \\ \sf \implies 7056 + {y}^{2} = 7225 \\ \\ \sf Substract \: 7056 \: from \: both \: sides : \\ \sf \implies (7056 - 7056) + {y}^{2} = 7225 - 7056 \\ \\ \sf 7056 - 7056 = 0 : \\ \sf \implies {y}^{2} = 7225 - 7056 \\ \\ \sf 7225 - 7056 = 169 : \\ \sf \implies {y}^{2} = 169 \\ \\ \sf 169 = {13}^{2} : \\ \sf \implies {y}^{2} = {13}^{2} \\ \\ \sf \implies y = \sqrt{ {13}^{2} } \\ \\ \sf \implies y = {13}^{ \cancel{2} \times \frac{1}{ \cancel{2}} } \\ \\ \sf \implies y = 13$

So,

Length of leg y of the right triangle = 13
