Answers:
9). 45/9 = 5
10). 2 *14² = 2* 196 = 392
11). 5 * 12 * 7 = 60 * 7 = 420
12). 1/2 * 9 * 12 = 54
13).1/2(24)(9 + 21) = 12 * 30 = 360
14). 14 * 13 = 182
15). 16 * 8 * 5 = 640
16). 75/5 = 15
17). 2(5²) = 2 * 25 = 50
18). 8(2.5 + 4.2) = 8 * 6.7 = 53.6
19). 1/2(3)(5 + 6) = 33/2 = 16.5
20). 3.14(6²) = 3.14 * 36 = 113.04
Answer and Step-by-step explanation:
90ft = a
55ft = b
50ft = c
Plug into equation.
29.4° is the answer.
There exists a similar question that would lead to the relationship of the given circumference to the unknown value. The radius of the larger circle is 12 cm. The formula for determining the circumference is,
C = 2πr
Substituting the known value,
C = 2π x 12 cm = 24π cm
Thus, the answer is letter B.
Q1. The answer is 100 hours
10 ml is for 1 hours
1l is for x hours
1l = 1000 ml
So, make a proportion:
10 ml is for 1 hours
1000 ml is for x
10 ml : 1h = 1000 ml : x
x = 1h * 1000 ml : 10 ml = 100 hours
Q2. The answers are:
1. kg - measurement of mass
2. cm² - measurement of area
3. L - measurement of volume (1L = 1 dm³)
4. m - measurement of length
