Solutions
1) <span>Lets use n as alex's number
</span>⇒ n x 1000
⇒ n ÷ 10
⇒ = 475
To solve the problem do the opposite steps
475 ÷ 1000 = n
n = <span>0.475
</span>
0.475 x 10 = n
n = 4.75
CHECK YOUR WORK
4.75 x 1000 = 4750
4750 ÷ 10 = 475
The answer is correct
⇒ The answer Alex is thinking of is 4.75
Answer:
720
Step-by-step explanation:
Answer: 11 units
Step-by-step explanation:
Given: On a coordinate plane, the coordinates of vertices R and T for a polygon are R(−6, 2) and T(5, 2).
To find : length of Side RT of the polygon.
Using distance formula to find distance between (a,b) and (c,d):
![d=\sqrt{(d-b)^2+(c-a)^2}](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B%28d-b%29%5E2%2B%28c-a%29%5E2%7D)
Length of RT = ![\sqrt{(2-2)^2+(5-(-6))^2}](https://tex.z-dn.net/?f=%5Csqrt%7B%282-2%29%5E2%2B%285-%28-6%29%29%5E2%7D)
![\\\\=\sqrt{0+(5+6)^2}\\\\= \sqrt{11^2}\\\\=11](https://tex.z-dn.net/?f=%5C%5C%5C%5C%3D%5Csqrt%7B0%2B%285%2B6%29%5E2%7D%5C%5C%5C%5C%3D%20%5Csqrt%7B11%5E2%7D%5C%5C%5C%5C%3D11)
hence, the length of RT = 11 units.
For this we can do 5.2 cents times 1.5 to determine how much zippy is costing the company per box extra so .052 x 1.5 is roughly 7.8 cents per box. So now 7.8 cents Times 484, .078 x 484 is roughly $37.752 cents or $37.75
