Given:
Cost of a jacket = $20
Then sells it to customers for 80% more than.
To find:
The selling price of the jacket
Solution:
We have,
Cost of a jacket = $20
Selling price = cost + 80% of cost
= [tex]20+\dfrac{80}{100}\times 20[/tex]
= [tex]20+\dfrac{8}{1}\times 2[/tex]
= [tex]20+16[/tex]
= [tex]36[/tex]
Therefore, the selling price of the jacket is $20.

-2(x+1)+4x<-10 what’s the solution
Equation/Question:
-2(x+1)+4x<-10 What’s the solution?
Answer/Way I did it:
1. Expand.
-2x-2+4x<-10
2. Simplify -2x-2+4x to 2x-2.
2x-2<-10
3. Add 2 to both sides.
2x<-10+2
4. Simplify -10+2 to −8.
2x<-8
5. Divide both sides by 2.
x<-8/2
6. Simplify 8/2 to 4.
x<−4

The standard deviation is 2.08.
What is Standard Deviation?A standard deviation (or σ) is a measure of how dispersed the data is in relation to the mean. Low standard deviation means data are clustered around the mean, and high standard deviation indicates data are more spread out.
We have the data,
X : 0 1 2 5 10
P(X) : 0.4 0.2 0.2 0.1 0.1
CF : 0.4 0.6 0.8 0.9 1
Sum of fx = 2.5
Mean = 2.5
Deviation X = -2.1 -2.3 -2.1 -2 -1.5
X² = 4.41 5.29 4.41 4 2.25
fX² = 1.764 1.058 0.882 0.4 2.225
Now, standard deviation
= √4.329/1
= 2.08

Which 3 angles can be constructed together to form a triangle?
90
60°
120°
70
20°
Answer:
90, 70, 20
Step-by-step explanation:
The measure of an angle is 180 so if you add up 90,70,and 20 you get a total of 180
Answer:
70, 20, 90
Step-by-step explanation:
For all triangles, the sum of the angles is 180.
I got these three angles 70, 20, 90.
To double check you can add all the angles together.
70 + 20 = 90, 90 + 90 = 180

Answer:
ab = 24
so ac is half, so
ac = 12
and the radius is 13,
draw a line from a to o
and its tall will be 13 because it is the radius and o is the center
now use Pythagoras rule
[tex] {a}^{2} + {b}^{2} = {c}^{2} [/tex]
put numbers
[tex] {12}^{2} + {b}^{2} = {13}^{2} [/tex]
and solve for b
b = 5
