Answer:
v = 99
Step-by-step explanation:
Given v varies directly as g then the equation relating them is
v = kg ← k is the constant of variation
To find k use the condition v = 36 when g = 4 , then
36 = 4k ( divide both sides by 4 )
9 = k
v = 9g ← equation of variation
When g = 11 , then
v = 9 × 11 = 99
Step-by-step explanation:
i think is this the answer
5×-4=-20
-20+2=18
Length (L): 2w + 3
width (w): w
Perimeter (P) = 2L + 2w
60 = 2(2w + 3) + 2(w)
60 = 4w + 6 + 2w
60 = 6w + 6
54 = 6w
9 = w
Length (L): 2w + 3 = 2(9) + 3 = 18 + 3 = 21
Answer: width = 9 feet, length = 21 feet
Answer:
3/8
Step-by-step explanation:
After spending 3/8 of her money on a bag, she has 5/8 of the original amount of money left. As she gave 2/5 of the remaining amount of money to her sister, she gave 1/4 of the original amount of money to her sister (5/8 × 2/5 = 1/4). Therefore, there's only 3/8 (1 - 3/8 - 1/4 = 3/8) of the original amount of money left in her bag.
1) We know, Circumference = 2πr
If radius is tripled, then, C' = 2π(3r) = 6πr = 3 * 2πr = 3 * C
So, Circumference will also get increased to it's triple value
2) We know, Area = πr²
If radius is doubled, π(2r)² = 4π²
So, Area will increase 4 times to it's intial value
Hope this helps!
