Here we are asked to find the smallest number which must be multiplied to 240 to make it a perfect square .
So , lets do prime factorisation of 240 .
Here , 240 = 2 × 120 .
= 2 × 2 × 60.
= 2 × 2 × 2 × 30.
= 2 × 2 × 2 × 2 × 3 × 5 .
Hence we got 240 = 2⁴ × 3¹ × 5¹ .
Now here we can see that , in order to make a perfect square it should be multiplied by 3 × 5 = 15 in order to make power of prime factors even .
The value of n is 10.
Solution:
Given expression:
<u>To solve this expression:</u>
Add 2 on both sides of the expression.
Multiply by 5 on both sides of the expression, we get
4n = 40
Divide by 4 on both sides of the expression, we get
n = 10
Hence the value of n is 10.
The equation will be y=-5/9x+16/3
Answer:
120
Step-by-step explanation:
15 x 16/2
You double 8 because your rotating around the y-axis
15% = .15
add 1.00 to include the original amount
9 *(1+0.15) = 10.35
so $10.35
