Answer:
41.4 degrees
Step-by-step explanation:
Find cos x by dividing both sides of this equation by 4:
cos x = 3/4 = 0.75
Using a calculator's inverse cosine function, find x:
arccos 0.75 = 0.723 radian, or
0.723 rad 180 deg
--------------- * ------------- = 41.4 degrees
1 pi rad
What is the area of this figure
So you basically have to find the area as if it were a rectangle, which would be 19*13, which is 247. Then, you find the area of the corner taken out and subrtact it, so 3*4 is 12, and 247-12 is 235.
How do you solve this

Answer:
n = 36
Step-by-step explanation:
The opposite sides of a parallelogram are congruent , that is
AB = DC , substitute values
[tex]\frac{2}{3}[/tex] n - 5 = [tex]\frac{1}{3}[/tex] n + 7 ( multiply through by 3 to clear the fractions )
2n - 15 = n + 21 ( subtract n from both sides )
n - 15 = 21 ( add 15 to both sides )
n = 36
Answer:
n = 36
Step-by-step explanation:
AB = DC because it is a parallelogram
so:
2/3n - 5= 1/3n + 7
simplify by adding 5 to each side of the equation:
2/3n = 1/3n + 12
simplify by subtracting 1/3n from both sides of the equation:
1/3n = 12
multiply both sides of the equation by 3:
n = 36

11 x minus 3 y = negative 17. Negative 4 x + 3 y = negative 18. Negative 7 x = negative 35 Negative 7 x = 35 7 x = negative 35 7 x = 35
Answer:
7 x = -35
Step-by-step explanation:
Which equation results from adding the equations in this system? 11 x minus 3 y = -17. Negative 4 x + 3 y = - 18.
- 7 x = negative 35
- 7 x = 35
7 x = negative 35
7 x = 35
In this problem we need to add the equations below i.e.
11x-3y = -17 and -4x+3y=-18
Adding both equations,
11x-3y+(-4x)+3y = -17+(-18)
7x= -35
or
7 x = negative 35
Hence, the correct option is (c).
Hiram asked his math class, "How many pets do you own?" He graphed the results on the line plot.
Which of the following is the BEST description of the data?
A.The mean is about 3.1; there are no gaps or outliersa peak at 2; and the data is not symmetrical.
B. The median is 2.5; the distribution is symmetrical; and there are no gaps or outliers.
C.The range is 7there is a peak at 5; and 6, 7and are outliers
D. The mode is 2; the data is skewed to the right; and there is a gap from 3-4
Answer:
B The median is 2.5; the distribution is symmetrical; and there are no gaps or outliers.
Step-by-step explanation
when I find the median it gets to 2, 3 so I get 2.5 no gaps and 0-7 isn't that far

Answer:
Nora
Step-by-step explanation:
M 20 : 50 = 2/5
N 11/25
2/5 = 10/25 < 11/25

Store A sells a watch for $50 and offers a 5% discount. Store B sells the same watch for $60 and offers a 20% discount.
1. What is the selling price of the watch at Store A?
2. What is the selling price of watch at Store B?
3. From which store should you buy the watch from?
Answer:
1. $47.50 2. $48 3. Store A

$50 - $2.50 = $47.50
Store A sells the watch for $47.50
STORE B
2. $60 * 0.2 = $12
$60 - $12 = $48
Store B sells the watch for $48
WHICH STORE IS BETTER
3. Store A is better as it sells the same watches for 50p less
