Hi! I'm happy to help!
Our net is composed of three shapes. Two congruent circles, and one rectangle. Our rectangle is 12cm by 2cm. Multiplied together, our rectangle has an area of 24cm².
We have our circle equation: A=[tex]\pi[/tex]r². It said to use 3 for pi, so our equation can be A=3(r²)
Radius is always half the length of our diameter. Our diameter is 4cm, so our radius will be 2cm.
Now, let's insert our values:
A=3(2²)
Now, let's solve:
A=3(4)
A=12
So, our area for one of the circles is 12cm². Since our circles are congruent, they will have the same area. Now, we have all 3 areas of all the shapes.
24+12+12=48cm²
Now, we need to name the figure. This is a net of a 3 dimensional shape. Since the net has circles on opposite sides, the rectangle must wrap around the circumference of both circles. This means that the 12cm must be equivalent to the circumference of the circle. Our circumference is 2[tex]\pi[/tex]r, or 2(3)(2), which is 12. So, with congruent circles on top and bottom, and a rectangle wrapping around, this seems to be a cylinder.
So, our Total Surface Area is 48cm², and the figure is a cylinder.

The temperature outside is dropping at a rate of 1.5 degrees each hour . It last is raining and the weather station predicts a changeover from rain to sleet when the temperature reaches 32*F or below . Currently the temperature is 53*F and the time is 8:30am when do you predict the changeover to sleet will occur?
Please help me
Answers
The changeover to sleet will happen at 10:30pm
The changeover to sleet is predicted to occur at 10:30 pm.
Given,
The temperature outside is dropping at a rate of 1.5 degrees each hour.
The changeover from rain to sleet is when the temperature reaches 32*F or below.
Currently, the temperature is 53*F and the time is 8:30 am.
We need to find at what time can we predict the changeover to sleet will occur.
What is temperature?Temperature is the measure of the hotness or coldness of an object with reference to some standard value.
We have,
Current temperature = 53*F at 8:30 am.
Rate of the drop of temperature = 1.5 degrees per hour.
Find the number of hours needed to drop from 53*F to 32*F.
53*F - 32*F = 21*F
We need to find how many hours required to drop to 21*F
1 hour = 1.5 degrees
Multiplying 21/1.5 on both sides.
21/1.5 x 1 hour = 21/1.5 x 1.5 degrees.
14 hours = 21 degrees
The number of hours required to drop from 53*F to 32*F is 14 hours.
8:30 am + 14 hours = 10:30 pm
Thus the changeover to sleet is predicted to occur at 10:30 pm.

Answers
The expression that represents the change in temperature for Day 1 is 23oF - (-8oF) and the value is 31oF
How to determine the expression that represents the change in temperature for Day 1?The given parameters from the question are:
Initial Temperature = -8oF
Final Temperature = 23oF
The expression that represents the change in temperature for Day 1 is represented as:
Change in temperature = Final Temperature - Initial Temperature
Substitute the known values in the above equation
Change in temperature = 23oF - (-8oF)
Remove the brackets
Change in temperature = 23oF + 8oF
Evaluate the sum
Change in temperature = 31oF
Hence, the expression that represents the change in temperature for Day 1 is 23oF - (-8oF) and the value is 31oF

Step-by-step explanation:
To find the value of x
a segment will be 180 degrees so now we can easily find the value of x
2x + 1 + 5x - 13 = 180 (line segment is 180 degrees)
7x - 12 = 180

The number of writing instruments in some teachers' desks is displayed in the dot plot. Which is greater the mean or the median? Explain your reasoning using the shape of the distribution.
please help..
30 points
Answers
The median is greater than the mean. From the shape of the distribution, the data set has more values on the left, so we can say it is skewed to the left. In every distribution that is skewed to the left, the median is always greater than the mean.
In the given chart we can deduce the following;
number of instruments that is 5 = 1number of instruments that is 6 = 1number of instruments that is 7 = 1number of instruments that is 8 = 1number of instruments that is 9 = 3number of instruments that is 10 = 4number of instruments that is 11 = 2number of instruments that is 12 = 1These numbers can be listed as follows;
5, 6, 7, 8, 9, 9, 9, 10, 10, 10, 10, 11, 11, 12
The median of these numbers is calculated as;
[tex]median = \frac{9+ 10}{2} = 9.5[/tex]
The mean of these numbers is calculated as;
[tex]mean = \frac{5+6+7+8+9+9+9+10+10+10+10+11+11+12}{14} = 9.07[/tex]
Thus, the median is greater than the mean.
Also, from the shape of the distribution, the data set has more values on the left, so we can say it is skewed to the left. In every distribution that is skewed to the left, the median is always greater than the mean. But if the distribution is skewed to the right, the mean is always greater than the median.
