3/2 = x/30........3 dogs to 2 cats = x dogs to 30 cats
cross multiply
(2)(x) = (3)(30)
2x = 90
x = 90/2
x = 45 dogs <===

Joaquin and Trisha are playing a game in which the lower median wins the game. Their scores are shown below. Joaquin's scores: 7
alekssr [168]

Answer:

Step-by-step explanation:

Given

Joaquin's score is 75,72,85,62,58,91

and Trisha's score is 92,90,55,76,91,74

Arranging score in order of value we get

Joaquin's : 58,62,72,75,85,91

Trisha's : 55,74,76,90,91,92

as no of values is even therefore their median is

Joaquin's=\frac{72+75}{2}=73.5

Trisha's =\frac{76+90}{2}=83

Therefore median of Joaquin's is lower

Thus Joaquin wins the game

If a triangle has side lengths 7, 10, and 12, is it a right triangle??
Vesnalui [34]

Answer:

No. Remember, a right angle must have a 90 degree angle. We can find the lengths with the Pythagorean Theorem.

Step-by-step explanation:

Given the length 7, 10, and 12, we can assume that 12 is the hypotenuse (it is the longest length).

- we can use 7 and 10 interchangeably.

Fill in the equation, a^2 + b^2 = c^2

                 where c = 12, and a or b = 7 or 10.

To indicate if the given lengths would form a right angle, we can only input 7 or 10, not both.

Therefore, 7^2 + b^2 = 12^2 or 10^2 + b^2 = 12^2

7^2 + b^2 = 12^2 ==> 49 + b^2 = 144 ==> <u>b= </u>\sqrt{95<u> ==> </u><u>9.746</u>

b= 9.7, not 10.

10^2 + b^2 = 12^2 ==> 100 + b^2 = 144 ==> <u>b = </u>\sqrt{44<u> ==> </u><u>6.633 </u>

b= 6.6, not 7.

Therefore, the lengths 7, 10, and 12, does NOT make a right triangle.

Hope this helps!
