8(number of soup) times 3 =x (number of vegetable cans)
Answer:
<h2>357°F </h2>
Step-by-step explanation:
Step one:
given data
actual reading= 350°F
thermometer reading 2% of the actual reading
Step two:
Required:
The thermometer reading
let us find 2% of 350°F
2/100*350°
=0.02*350
=7°F
Hence the thermometer reading is 7°F greater than 350°F
The thermometer reading is 350+7=357°F

Answer: ![3\sqrt{7}](https://tex.z-dn.net/?f=3%5Csqrt%7B7%7D)
</h3>
3*sqrt(7)
3 times the square root of 7
====================================================
Explanation:
I'm assuming the V stands for square root. You can write sqrt(63).
![\sqrt{63} = \sqrt{9*7}\\\\\sqrt{63} = \sqrt{9}*\sqrt{7}\\\\\sqrt{63} = 3\sqrt{7}](https://tex.z-dn.net/?f=%5Csqrt%7B63%7D%20%3D%20%5Csqrt%7B9%2A7%7D%5C%5C%5C%5C%5Csqrt%7B63%7D%20%3D%20%5Csqrt%7B9%7D%2A%5Csqrt%7B7%7D%5C%5C%5C%5C%5Csqrt%7B63%7D%20%3D%203%5Csqrt%7B7%7D)
The idea is to factor 63 in such a way that one factor is the largest perfect square possible, that way we can pull the root apart to simplify as shown above. The rule I used for the second step is ![\sqrt{x*y} = \sqrt{x}*\sqrt{y}](https://tex.z-dn.net/?f=%5Csqrt%7Bx%2Ay%7D%20%3D%20%5Csqrt%7Bx%7D%2A%5Csqrt%7By%7D)
