Answer:
The correct option is A
Step-by-step explanation:
The expression is
2y3 - 27 + 5y2 + (25 / 5)
Substitute the value of y=2 in the expression:
=2(2)³-27+5(2)²+(25/5)
We know that 2³ means multiply 2 three times
2³= 2*2*2=8
Likewise 2²=2*2=4
=2(8)-27+5(4)+(25/5)
=16-27+20+25/5
Now take the L.C.M which is 5
=80-135+100+25/5
Solve the values in the numerator:
=70/5
=14
Thus the correct option is A....
Answer:
-5/6
Step-by-step explanation:
This is because we can substitute p for 2/3.
(3/4 x 2/3) - (2/1 x 2/3)
This shall equal:
6/12 - 4/3
In order to subtract, we need the same denominator meaning we need that three on 4/3 to be 12. So multiply 4/3 and 4/4
Equation shall be like this:
6/12 - 16/12
Now subtract keep the denominator the same!
-10/12
Simply/reduce (divide by 2/2)
-5/6!!
Answer:
40.5
Step-by-step explanation:
(n-2)*180
(7-2)*180=5*180=900
10p+135+149+121+90=900
10p=-495+900=405
p=40.5
There are 6 faces on each dice and the total possible combinations possible = 6*6 = 36 combinations.
Of those 36 combinations, the combinations of sum less than 6 are:
1&1 2&1 3&1 4&1
1&2 2&2 3&2
1&3 2&3
1&4
Thus, 10/36 :-)
