133.875
This is the answer because we are given the length and the width of this floor. We are assuming it is a regular rectangle.
So we just multiply the length and the width which is 12.74 x 10.5, which comes out to 133.875
Answer:
Step-by-step explanation:
I am very good at Pythagorean theorem I did it this year. So A=85 E=73 S=37 L=66.5 (or 65) T=82 P=53 D=10 O=89 C=17
To do this it is actually like the easiest thing to do in math. The formula is A²+B²=C². To do this it is easier with a scientific calculator. If you don't have one you can use this online calculator: desmos.com/scientific
Step 1. get the two number and square (²) them ( multiply that number by it) For Example 30 multiplied by 30. Or on the calculator I gave you just do 30²+40²
Step 2. After that you will get 2500. Then on the calculator get this symbol √ and but the number 2500 in front of it. it should look like this. √2500.
Step 3. After that you will get 50 which is your answer. And that is how you do Pythagorean theorem.
I hope that helped you. If you don't have a scientific calculator you can use the link I provided above. If you can't use it I reccomend buying one.
Answer: ![4\ months](https://tex.z-dn.net/?f=4%5C%20months)
Step-by-step explanation:
Let be "P" the number of months Huang Yi must work as a paleontologist and "S" the number of months she must work as a sculptor to make at least $50,000
The inequality given in the exercise is:
![5500P+4500S \geq 50000](https://tex.z-dn.net/?f=5500P%2B4500S%20%5Cgeq%2050000)
Knowing that this year she worked for 6 months as a paleontologist, we can identify that:
![P=6](https://tex.z-dn.net/?f=P%3D6)
So in order to calculate the minimum number of months that Huang Yi must work as a sculptor to reach her goal, we have to substitute that value of "P" into the inequality and then we must solve for "S".
Then, we get:
![5500(6)+4500S \geq 50000\\\\33000+4500S \geq 50000\\\\4500S \geq 50000-33000\\\\4500S\geq 17000\\\\S\geq \frac{17000}{4500}\\\\S\geq 3.77](https://tex.z-dn.net/?f=5500%286%29%2B4500S%20%5Cgeq%2050000%5C%5C%5C%5C33000%2B4500S%20%5Cgeq%2050000%5C%5C%5C%5C4500S%20%5Cgeq%2050000-33000%5C%5C%5C%5C4500S%5Cgeq%2017000%5C%5C%5C%5CS%5Cgeq%20%5Cfrac%7B17000%7D%7B4500%7D%5C%5C%5C%5CS%5Cgeq%203.77)
Therefore, we can conclude <em>that minimum whole number of months that she must work as a sculptor to reach her goal is:</em>

Answer:
B. A water wheel in a dry river
Step-by-step explanation:
Work is said to be done when a force moves a body or an object through a certain distance in the direction of the force. Thus for work to be done, force and distance are required.
i.e Work done = Force x distance
It is measured in Joules.
Also, the work done by an object could be a measured of potential energy.
So that,
Work done = potential energy = mass x gravitational force x height
Considering the collage in the question, since the water wheel is in a dry river no work is done. Water wheel is a device that functions through the flow of water body, thus causing its rotation.
