Answer:

The energy in object is 3.8 Kilo Joules.  

Step-by-step explanation:

We are given the following in the question:

Mass = 20 kg

Height,h = 20 m

g=9.5 m/s^2

Formula:

Potential energy  =

E = Mgh

Putting value we get,

E = 20(20)(9.5)\\E = 3800~J\\E = 3.8~KJ

Thus, the energy in object is 3.8 Kilo Joules.

Terrell got 1 3/4 pounds of ground meat and 2 1/6 of ground chicken. he used 1 2/3 pounds of ground chicken to make a casserole.
babunello [35]

Answer:

Okay so we have to solve this in separate parts. Like so, its wiill go like this: 2+ 1/6 - 1 - 2/3. So we see that we have 2 and 1 as whole. Subtract 2 - 1 is 1 right. Now for fractional part 1/6 - 2/3. Since its uneven, we have to find the LCD which is 6. This forms of our fractions into 1/6- 4/6. 1/6 - 4/6 is 3/6. simplify it would result in 1/2.  The amount of ground chicken that Terrell has left is 1/2.

What does the correlation show about the relationship between temperature and sales of ice cream
kvasek [131]

The graph is missing. So is the set of data point values. However, I can assume that as the temperature goes up, then so does the sale of ice cream. It's not a perfect relationship, but there is a strong positive correlation between the two variables.

A positive correlation means that as one variable increases, so does the other. Also, it means that if one variable decreases, then the other variable decreases as well. The two variables move in the same direction together.
