The area of <span>rhombus is product of two diagonals divided by 2

So you have 22 inches and 13 inches so that would be 22</span>·13/2 = 143

Final answer: 143 in²

The line passes through (9,8) and is perpendicular to x-2y=-16

pickupchik [31]

The equation of line perpendicular to x-2y=-16 passing through (9,8) is: y=-2x+26

Step-by-step explanation:

Given

$x-2y=-16\\Adding\ 2y\ on\ both\ sides\\x=2y-16\\Adding\ 16\ on\ both\ sides\\x+16=2y-16+16\\x+16=2y\\2y=x+16\\Dividing\ both\ sides\ by\ 2\\\frac{2y}{2}=\frac{x+16}{2}\\y=\frac{x}{2}+\frac{16}{2}\\y=\frac{1}{2}x+8\\$

The equation is in slope-intercept form, the coefficient of x will be the slope of given line. The slope is: 1/2

As the product of slopes of two perpendicular lines is -1.

$\frac{1}{2}*m=-1\\m=-1*\frac{2}{1}\\m=-2$

Slope intercept form is:

$y=mx+b$

Putting the value of slope

y=-2x+b

To find the value of b, putting (9,8) in the equation

$8=-2(9)+b\\8=-18+b\\b=8+18\\b=26$

Putting the values of b and m

$y=-2x+26$

Hence,

The equation of line perpendicular to x-2y=-16 passing through (9,8) is: y=-2x+26

after a party, you have 2/5 of the brownies you made left over. there are 16 left. how many brownies did you make for the party

vodomira [7]

16 = 2/5
16 ÷ 2 = 2/5 ÷ 2/1
8 = 1/5
8 * 5 = 1/5 * 5
40 = 5/5
You started the party with 40 brownies

Math question Informatin in dot plots

kozerog [31]

Answer:

Step-by-step explanation:

Range = difference between the highest and the lowest

Mode = Data that occurs the most time

Median = Arrange the data in ascending order. The middle data is the median. If number of data is even, median is the average of the two middle terms.

1) Range = 28 -21 = 7

Mode = 25

Number of data (Count the total dots) = 14

Median = average of 7th and 8th term

Median = (25+25)/2 = 50/2 = 25

2) Range = 0.18 - 0.11 = 0.07

Mode = 0.15 and 0.16

Number of data = 23

Median =12th term = 0.15

Only 16 -22 even plz it's due tomorrow

sdas [7]

16: 8/25; 38%; .41
18: 84% 43/50; 7/8; .91
20: 26.8%; 2.26; 2 2/5; 2.62; 271%
22: 21/25= 84% so yes
