Answer: x = 4
<u>Step-by-step explanation:</u>
6ˣ = 1296
6ˣ = 6⁴
Since they have the same base, set the exponents equal to each other:
x = 4
Circunference=2 times pi time r
if pi=3 and r=4.5
circunerence=2 times 3 times 4.5=3 times 2 tiimes 4.5=3 times 9=27
answer is 27cm
Answer:
The weight of 12 tennis balls = 691. 2 grams
Step-by-step explanation:
The weight of each tennis ball = 57.6 grams
So, the weight of 12 balls = 12 x ( weight of 1 ball)
= 12 x 57.6 grams
= 691.2 grams
⇒12 balls weigh 691.2 grams
Hence, the weight of 12 tennis balls = 691. 2 grams
Answer:
i) k = 36.8
ii)y = 36.8/square root of x
iii)y = 1.4
Step-by-step explanation:
If y is inversely proportional to square root of x;
then the two variables are related by,
y = k/ square root of x
i)Value of k when...x = 8 and y = 13,
substitute into the equation above..so as to find the value of k
13 = k/square root of 8
;k = 13 × square root of 8
;k = 36.8
ii)Then substitute the value of k with...36.8
y = 36.8/square root of x
iii)If x = 27...then y =;
y = 36.8/27
y = 1.4
