Well, the first one is 2/40=1/20. The 2nd one is 1/39. You multiply these to get 1/780.
Answer:
Total walk she did around the pool every morning = 141.3
Step-by-step explanation:
Given - Kriti has a circular swimming pool in her house. The radius of the swimming pool is 22.5 cm. She walks one round every morning before diving in the pool.
To find - How far does she walk around the pool every morning?
Proof -
Given that, the swimming pool is circular in shape.
So,
1 round of circle = Circumference of circle.
As we know that,
Circumference = 
= 
= 141.3
∴ we get
Total walk she did around the pool every morning = 141.3
Answer:
The answer is 2 and 1/4.
Step-by-step explanation:
You have to do 9 x 1/4 and then you get 2 & 1/4
Solution:
1. Move all terms to one side
<span>25{x}^{2}+40x+16-28=0</span>
2. Simplify <span>25{x}^{2}+40x+16-28 to <span>25<span>x<span><span>2</span><span></span></span></span>+40x</span></span><span><span>−12</span></span>
<span>25{x}^{2}+40x-12=0</span>
3. Apply the Quadratic Formula<span>x=\frac{-40+20\sqrt{7}}{50},\frac{-40-20\sqrt{7}}{50}
</span>
4. Simplify solutions
<span>x=-\frac{2(2-\sqrt{7})}{5},-\frac{2(2+\sqrt{7})}{5}</span>
Done!
