Answer:
2
Step-by-step explanation:
15+-13 = 2
Answer:
this question answer is 11
The number is 63, so the quotient is 2.
Two digit numbers divisible by 21:
21, 42, 63, 84
21: 2-1 = 1 * 3.5 = 3.5
3.5*2*1 = 7 but 7 does not equal 21
42: 4-2 = 2 * 3.5 = 7
3.5*4*2 = 28 does not equal 42
63: 6-3 = 3*3.5 = 13.5
3.5*6*3 = 63 :)
Check:
21(6-3)=21(3)= 63 :)
3.5(6)(3) = 21(3) = 63 :)
63: 6/3 = 2
The ratio of the height of the stick to the length of its shadow is equal to the ratio of the height of the tree to the length of its shadow.
x - the height of the tree
The tree is 36 ft tall.
Note that multip. 10 by 2 results in 20; mult. 20 by 2 results in 40, and so on. So the common ratio is 2.
