Answer:
h = 6 cm
Step-by-step explanation:
Atriangle = b×h/2
18cm² = 6cm×h/2
36cm² = 6cm×h
h = 36cm²/6cm
h = 6 cm

Step-by-step explanation:
Exactly 11 pencils were added
Blue pencils became highest, for it to be highest, it has to be more than all the other ones. So if 10 is added to the original number it will make it 13 higher than all, and the remaining one is added to green to make it 12 higher than red.
Answer:
Number of birds = 13
Explanation:
An animal shelter spends $1.50 per day to care for each bird and $3.50 per day to care for each cat.
Let the number of bird be 'a' and number of cat be 'b'.
Total money spent = 103.5
1.5 a + 3.5 b = 103.5 ------------------------equation 1
Total number of birds and cats = 37
a + b = 37 ------------------------equation 2
1.5 x equation 2
1.5 a + 1.5 b = 55.5 ------------------equation 3
equation 1 - equation 3
2 b = 103.5 - 55.5 = 48
b = 24
Substituting in equation 2
a = 37 - 24 = 13
Number of birds = 13, Number of cats = 24.
