NEED HELP FAST!! A group of students performed an experiment to prove the law of conservation of energy. In the experiment, a fl

ask containing water at room temperature was shaken vigorously for a few minutes. The table shows a partial record of the temperature of the water before and after shaking. Experimental Record Temperature Before Shaking 20 °C After Shaking Unknown What best predicts the unknown temperature? A- Less than 20 °C because the total energy of the system after shaking is lower B- Greater than 20 °C because the total energy of the system after shaking is higher C- Less than 20 °C, because the mechanical energy from shaking transforms to thermal energy D -Greater than 20 °C, because the mechanical energy from shaking transforms to thermal energy

How many quarters are thee in 4 1/2​
Neko [114]

Hi there!

quarter:18

<u><em>1.Find common denominator in 4 and 1/2:</em></u>

<u><em /></u>4=\frac{1}{4}<u><em /></u>

<u><em /></u>\frac{1}{2}=\frac{2}{4}<u><em /></u>

<u><em>2.Convert 4 2/4 into mixed number:</em></u>

<u><em /></u>4\frac{2}{4}=\frac{18}{4}<u><em /></u>

<u><em>3.Divide 18/4 by 1/4:</em></u>

<u><em /></u>\frac{18}{4}*\frac{1}{4}=18<u><em /></u>

Therefore, there is 18 quarters in 4 1/2.

The sum of two numbers is
lara [203]
Answer:
The larger number is 60
The smaller number is 14

Explanation:
Assume that the larger number is x and that the smaller number id y.

We are given that:
1- The sum of the two numbers is 74. This means that:
x + y = 74
This equation can be rewritten as:
x = 74 - y .............> I
2- Four times the smaller number (4y) subtracted from the larger number (x), the result would be 4. This means that:
x - 4y = 4 ..............> II

Substitute with I in II and solve for y as follows:
x - 4y = 4
74 - y - 4y = 4
74 - 5y = 4
5y = 70
y = 70/5
y = 14

Substitute with the value of y in equation I to get x as follows:
x = 74 - y
x = 74 - 14
x = 60

Hope this helps :)
