Answer:
3/10, 0.3, 30%
Step-by-step explanation:
So, we know that there are 10 roses, and that 2 of them are daisies and of half of them are tulips. This means that there and 2 daisies and 5 (half of 10) tulips. Lets assume the rest of the flowers are roses (otherwise, this question would be unsolvable). So since there are 2 daisies and 5 tulips, to find the number of roses, we would subtract the number of daises and the number of tulips from the total number of flowers. 10 - 2 - 5 = 3. So there are 3 roses.
What fractions are roses?:
So we know that there are 3 roses, and that there are 10 flowers total. This means that the fraction of roses is 3/10.
Write the fractions of roses as a decimal and a percent?
Since the denominator of the fraction of roses is 10, the fraction of roses as a decimal would be 0.3, and the number of roses as a percent would be 30%.
I hope this helps. :)
Answer:
x =58
Step-by-step explanation:
The angles are complementary which means they add to 90 degrees
32+ x = 90
Subtract 32 from each side
32+x-32 = 90-32
x =58
Answer:
B = 48.7°, C = 61.3°, b = 12.0
Step-by-step explanation:
A triangle solver makes short work of this. (See below.)
_____
If you're interested in solving this using only calculator trig functions (and not the solver function), you can use the Law of Sines:
sin(C)/c = sin(A)/a
sin(C) = (c/a)sin(A)
C = arcsin(c/a·sin(A)) = arcsin(14/15·sin(70°))
C ≈ 61.3°
From the sum of angles, the third angle is ...
B = 180° -A -C = 180° -70° -61.3°
B = 48.7°
Again from the Law of Sines:
b/sin(B) = a/sin(A)
b = a·sin(B)/sin(A) = 15·sin(48.7°)/sin(70°)
b ≈ 12.0
