Ricardo spends 2 2/3 hours practicing soccer on
ladessa [460]

Answer:

10 7/12 hours

Step-by-step explanation:

so we have to multiply 2 2/3 twice since he does that many hours for 2 days. We then have to multiply 1 3/4 three times since he does that many hours for 3 days. Lets first convert 2 2/3 into a mixed fraction. 2 2/3 = 3 times 2 =6 +2=8 over 3. 1 3/4=4 times 1=4+3=7 over 4. 8/3 times 2 equals 16/3 which eqials

5 1/3 hours. 7/4 times 3 equals to 21/4 which equals to 5 1/4. Lets now add

5 1/3 and 5 1/4. 5+5=10 but the fractions are not the same. Therefore, we need to make it to a common denominator. 4 times 3 equals to 12 so 4/12 plus 3/12 equals 7/12. Final answer equals to 10 7/12.

EASY, answer this simple question :) *What kind of angles are 2 and 3?
IgorLugansk [536]

Answer:

∠2   =  ∠3 is a pair of  Vertical Angles.

Step-by-step explanation:

Whenever two lines intersect with each other, the angle formed between them is called Vertically Opposite Angle.

Here, line l intersects the traversal so,

the angle formed between them  ∠1 and ∠4 are vertically opposite.

So, ∠1 =  ∠4

Also, as ∠1 +  ∠3 =  ∠2  + ∠4 = 180°  (LINEAR PAIRS)

So,  ∠3   =  ∠2 are also vertical angles.
