Answer:

Step-by-step explanation:

$n,\ n+2-\text{two consecutive even integers}\\\\\text{The equation:}\\\\n+(n+2)=74\\\\n+n+2=74\qquad\text{subtract 2 from both sides}\\\\2n=72\qquad\text{divide both sides by 2}\\\\n=36\\\\n+2=36+2=38$

In triangle EFG, angle E equals 8x-16, angle F equals x+8, and angle G equals 2x-10. What is the value of x?

Stels [109]

Answer: The value of x= 18

Step-by-step explanation:

Given: In triangle EFG, angle E equals 8x-16, angle F equals x+8, and angle G equals 2x-10.

The sum of all angles of a triangle is 180°.

Therefore, in triangle EFG

∠E + ∠F +∠G= 180°

⇒ 8x-16 +x+8+ 2x-10 = 180

⇒ 11x-18= 180

⇒ 11x = 180+18

⇒11x=198

⇒ x= 18 [Divide both sides by 11]

Hence, the value of x= 18

ruslelena [56]

Answer:

0.3

Step-by-step explanation:

Given:

Number of small dogs = 18

Number of medium-sized dogs = 12

Number of large dogs = 10

To find: probability that a medium-sized dog will be chosen

Solution:

Probability refers to chances of occurrence of some event.

Probability = number of favourable outcomes/total number of outcomes

Total number of dogs = 18 + 12 + 10 = 40

Number of medium-sized dogs = 12

So,

probability that a medium-sized dog will be chosen = Number of medium-sized dogs/Total number of dogs = $\frac{12}{40}=0.3$

A triangle ABC has A(1,-4) B(3,-1) C(3,-8).Find the length of the sides AB and AC

mr_godi [17]

Answer:

Step-by-step explanation:

AB= $\sqrt{(1^{2} -3^{2})+((-4)^{2} -(-1)^{2} ) }$

= $\sqrt{7}$

AC= $\sqrt{(3^{2} -1^{2} )+((-8)^{2}- (-4)^{2} )} \\$

= $\sqrt{56}$
