Answer:
11.1%
Step-by-step explanation:
percentage decrease is calculated as
[tex]\frac{decrease}{original}[/tex] × 100%
decrease = 18 - 16 = 2 , then
percent decrease = [tex]\frac{2}{18}[/tex] × 100% = 11.1% ( to the nearest tenth )

Answer:
-1/3
Step-by-step explanation:
help please!! find the area of each triangle. round intermediate values to the nearest tenth. use the rounded values to calculate the next value.
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

Solve e/g + f = h for e
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

The value of a new $5400 sailboat decreases 10% per year. Find its value after 5 years. Round to the nearest penny.
Answer:
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

what is the median and mode for the numbers 40, 28, 24, 37, 43, 26, 30, 36
Answer:
Median
Assending order =24,26,28,30,36,37,40,43
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
What is Median?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

Answer:
$16.05
Step-by-step explanation:
50% of 10.00
0.50 x 10.00 = 5.00
10.00 + 5.00 = 15.00
7% of 15.00

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]
