Answer:
6/8, 9/12, 12/16
Step-by-step explanation:
Multiply the numerator and denominator by the same amount to maintain the same ration.
Answer:
yes this is correct
Step-by-step explanation:
Let us denote the smaller even integer by
.
Then, the next even integer must be
.
To verify, set
as any even number, say
.
Then, the next even integer must be 2 more than this number, i.e.
.
The sum of these two consecutive even integers can be expressed as:
We are told that this sum divided by four is 189.5, i.e.
Multiplying both sides by 4 will reverse the division:
Subtracting 2 from each side will reverse the addition:
Dividing both sides by 2 will reverse the multiplication:
Therefore, the two consecutive integers must be
378 and
380.

Answer:
cosR =
Step-by-step explanation:
assuming the right triangle has ∠ Q = 90° with legs 5 and 12
then this is a 5- 12- 13 right triangle with hypotenuse PR = 13 cm
then
cosR = = =
