Answer:
Yes she can.
Step-by-step explanation:
Val can make 6 slides in an hour.
1/6 * 60 minutes = 10 minutes. per slide
10 20 30 40 50 60 gives you six sldes, 1 every ten minutes.
=====================
In one hour, she can produce 6 slides.
In two hours, she can produce 12 slides (2 * 6 = 12)
Since she only needs 1 hour and 40 minutes to produce 10 slides, she is under her time limit of 2 hours.
Answer:
90°, 51° and 39°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Let the smallest angle be x then the other angle is x + 12, thus
x + x + 12 + 90 = 180, that is
2x + 102 = 180 ( subtract 102 from both sides )
2x = 78 ( divide both sides by 2 )
x = 39
The other angle is 39 + 12 = 51
The 3 angles are 90°, 51° and 39°
