Answer: 1: 7 5/12 yards 2: 16.4 miles
Step-by-step explanation:
4 3/4+2 2/3 = 7 5/12
7.5+8.9= 16.4
The answer is A. 7.8 cm3. We know that 1 mm=0.1 cm. So 1 mm3=0.001 cm3. Then the 7800 mm3 equals to 7.8 cm3.
Answer:
-2, 6, 20 ,...
Step-by-step explanation:
3n² +5n -2
if n=0 , then 3*0² +5*0 -2= -2
if n=1, then 3*1² +5*1 -2 = 3+5-2 = 6
if nu 2, then 3*2² +5*2 -2 = 12 +10 -2 = 20
Answer:
p = 16
Step-by-step explanation:
Given p is directly proportional to (q + 2)² then the equation relating them is
p = k(q + 2)² ← k is the constant of proportion
To find k use the condition when q = 1, p = 1
1 = k(1 + 2)² = k × 3² = 9k ( divide both sides by 9 )
= k
p = (q + 2)² ← equation of proportion
When q = 10 , then
p = × (10 + 2)² = × 12² = × 144 = 16
