Step-by-step explanation:

Perimeter of triangle =  4x - 3 + x + 9 + 8

                                   = 4x + x - 3 + 9 + 8

                                  = 5x + 14

Area  = [tex]\frac{1}{2}*base *height[/tex]

         [tex]= \dfrac{1}{2}*8*3x\\\\= 4 * 3x\\\\= 12x[/tex]

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.

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.

Answer:

[tex]3\sqrt{13}[/tex]

Step-by-step explanation:

Hi there!

We want to find the distance between the points (2, -2) and (-4, 7).

To do that, we can use the distance formula.

The distance formula is given as [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex], where [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] are points

We have everything needed to find the distance, but let's label the values of the points to avoid any confusion

[tex]x_1=2\\y_1=-2\\x_2=-4\\y_2=7[/tex]

Now substitute those values into the formula and solve

[tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

[tex]\sqrt{(-4-2)^2+(7--2)^2}[/tex]

Simplify

[tex]\sqrt{(-4-2)^2+(7+2)^2}[/tex]

[tex]\sqrt{(-6)^2+(9)^2}[/tex]

Square the numbers under the radical

[tex]\sqrt{36+81}[/tex]

Add the numbers under the radical together

[tex]\sqrt{117}[/tex]

Simplify the square root

The expression that represents the change in temperature for Day 1 is 23oF - (-8oF) and the value is 31oF

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

Answer:

g (f(2)) = 3

Step-by-step explanation:

f (x) = x2 – 4

g(x) = x + 3

g (f (2)) =?

Find f(2) first

f (x) = x2 – 4

f (2) = 2^2- 4

= 0

Now put this in your g(x)

g(x) = x + 3

g (f(2)) = (f(2)) + 3

And u alredy know f(2) =0, so just put it in

g (f(2)) = 0 + 3

=3

Answer:

Step-by-step explanation:

[tex]19 + 1.5(10m-8) = 127[/tex]

Multiply both sides by 10

[tex]190+15(10m-8)=1270[/tex]

Subtract 190 from both sides

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;

These 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.

x = 27.42

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

7x = 180 +12

7x = 192

x = 192/7

x = 27.42
