Answer:

e=g(h-f) or e=gh - gf

Step-by-step explanation:

Answer:

e = hg - fg

Step-by-step explanation:

Given

[tex]\frac{e}{g}[/tex] + f = h ( multiply through by g to clear the fraction )

e + fg = hg ( subtract fg from both sides )

e = hg - fg

Step-by-step explanation:

Area of a triangle = (1/2)*base*height

For both of the triangles, you have the base (8.8 for the triangle on the left, 7.6 for the triangle on the right) and the side lengths, but not the height. But since both are isosceles triangles, you can find the height using the pythagorean theorem.

5.

First divide the triangle vertically into two triangles (see attached picture). Now you have two right triangles, you can apply the pythagorean theorem on either one of them to find the height. The pythagorean theorem says that for a right triangle, [tex]a^2+b^2=c^2[/tex], where c is the hypotenuse and a and b are the sides of the triangle.

Substituting the given values and rounding to nearest tenth:

[tex]a^2+b^2=c^2\\4.4^2+h^2=10^2\\h=9.0[/tex]

Now that you have the height, you can find the area of the entire triangle.

A = (1/2)*base*height

A = (1/2)*8.8*9.0 = 39.6

6.

Same procedure.

[tex]a^2+b^2=c^2\\3.8^2+h^2=10^2\\h=9.2[/tex]

A = (1/2)*base*height

A = (1/2)*7.6*9.2 = 35.0

Answer:

B. [tex]A(h) =3h^3 -h[/tex]

Step-by-step explanation:

Given is the figure of a trapezoid with following descriptions.

[tex] b_1=2h^2 +2[/tex]

[tex] b_2 =2h^2 +2+ 2h^2-6=4h^2 - 4[/tex]

[tex] height = h[/tex]

Now, by formula of area of trapezoid, we have:

[tex]A(h) =\frac{1}{2} (b_1+b_2)h[/tex]

[tex]A(h) =\frac{1}{2} (2h^2 +2+4h^2 - 4)h[/tex]

[tex]A(h) =\frac{1}{2} (6h^2 -2)h[/tex]

[tex]A(h) =\frac{1}{2} (6h^3 -2h)[/tex]

[tex]A(h) =\frac{1}{2} \times 2(3h^3 -h)[/tex]

[tex]A(h) =(3h^3 -h)[/tex]

[tex]A(h) =3h^3 -h[/tex]

Answer:

40=5×8

Step-by-step explanation:

I think, hope this helps

The equation for the number 40 is 5 times as many as 8 is; 40=5×8

An equation represents equality of two or more mathematical expression.

A mathematical equation is a statement with two equal sides and an equal sign in between. An equation is, for instance, 4 + 6 = 10. Both 4 + 6 and 10 can be seen on the left and right sides of the equal sign, respectively.

Solutions to an equation are those values of the variables involved in that equation for which the equation is true.

We are given that the number 40 is 5 times as many as 8

40 is 5 times as many as 8 means

5×8 = 40

Then the equation will be;

40=5×8

It is even no of obs

Therefore the two middle obs are 30,36

Therefore median 30+36/2

Therefore median 66/2

Therefore median is 33

There is no mode in the following obs

If you are helped with my answer pls tag me brianliest I really want it

THANK YOU.......

The median of the numbers is M = 33 and the mode is not defined

The median is the value that's exactly in the middle of a data set when it is ordered. It's a measure of central tendency that separates the lowest 50% from the highest 50% of values. The steps for finding the median differ depending on whether you have an odd or an even number of data points

Arrange the data points from smallest to largest.

If the number of data points is odd, the median is the middle data point in the list.

If the number of data points is even, the median is the average of the two middle data points in the list.

Given data ,

Let the set of numbers be represented as set A

Now , the value of A is

A = { 40, 28, 24, 37, 43, 26, 30, 36 }

Arranging the numbers in the ascending order , we get

A = { 24 , 26 , 28 , 30 , 36 , 37 , 40 , 43 }

Now , the total number of elements in the set A = 8

So , the median is the average of the two middle data points in the list.

M = ( 30 + 36 ) / 2

M = 33

The mode of the numbers is the numbers that appears the most often

So , mode is not defined

Hence , the median is M = 33

FV= $3,352.98

Step-by-step explanation:

Giving the following information:

Initial investment (PV)= $5,400

Number of periods (n)= 5 years

Interest rate (i)= 10%

To calculate the future value (FV), we need to use the following formula:

FV= PV / (1 + i)^n

FV= 5,400 / (1.1^5)

FV= $3,352.98

Alright, this is a fairly simple equation if you consider the overall question. As the question states, every 5 of out 7 students voted in the election. This means that five sevenths of all students in the school casted a vote.

Now, what can we do with this information? Well, we know that there were 1095 votes in total. This means that five sevenths of the school who voted represents 1095 students.

Can you see the equation you need to write now? Let's use a simple equation with the variable 's' to represent the total number of students:

[tex]\frac{5}{7}[/tex] * s = 1095

As I elaborated earlier, this equation essentially means "5/7 of the entire student population is 1095 students." Now, we just need to isolate the variable 's' to get our final answer.

To get rid of the denominator, let's multiply both sides by 7:

[tex]\frac{5s}{7}[/tex] * 7 = 1095 * 7

5s = 7665

Finish it off by dividing both sides by 5 to get rid of s's coefficient:

[tex]\frac{5s}{5}[/tex] = [tex]\frac{7665}{5}[/tex]

s = 1533

There are 1533 total students in the school

And that's it! If you have any questions about how I solved it, feel free to ask!
