Karolina [17]3 years ago
6 0

Answer:

11. x=10, y=14.1421356237

12. x=12.124355653, y=14

Step-by-step explanation:

11. Use tan and pythagorus

tanA=opposite/adjacent

tan45=x/10

10(1)=x

x=10

a²=b²+c²

y²=x²+10²

y²=10²+10²

y²=100+100

y=√200=14.1421356237

12. Use tan and pythagorus

tanA=opposite/adjacent

tan30=7/x

0.57735026919x=7

x=7/0.57735026919

x=12.124355653

a²=b²+c²

y²=x²+7²

y²=12.124355653²+7²

y²=147+49

y=√196=14

A company loses $780 as a result of shipping delay the 6 owners of the company must share the loss equally.
tekilochka [14]

A) Change in profit for each owner = -780/8

B) Change in profit for each owner = -$130

The total loss  = $780

Number of owners = 6

The 6 owners must share the loss equally

The change in profit for each owner will be the original profit less 780/6

That is -780/6

Evaluating -780/6

Change in profit for each owner = -$130

Given ΔABC with A(–4, –2), B(4, 4), and C(18, –8), write the equation for the line containing median segment The term is line se
Monica [59]
Here we want to find the equation of the line containing the median CP.

P, being the midpoint of AB can be found using the midpoint formula as:

\displaystyle{ P=( \frac{-4+4}{2} ,  \frac{-2+4}{2} )=(0, 1).


The slope m of the line through CP can be found by the slope formula using points C(18, -8) and P(0, 1):

\displaystyle{ m= \frac{y_2-y_1}{x_2-x_1}= \frac{-8-1}{18-0}= \frac{-9}{18}= \frac{-1}{2}.


Now, we can write the equation of the line with slope -1/2, passing through
P(0, 1):

y-1= \frac{-1}{2}(x-0)\\\\y= -\frac{1}{2}x+1.


Answer: y=-\frac{1}{2}x+1

Deion has the following data: 47, u, 41, 38. if the range is 10 which could "U" be ?
slavikrds [6]

deion has the following data: 47, u, 41, 38. if the range is 10 which could "U" be ?​

REmember that

The range of a set of data is the difference between the highest and lowest values in the set

If U is the highest value

Range=U-38

range=10

so

10=U-38

U=10+38

U=48

If U is the lowest value

Range=47-U

10=47-U

U=47-10

U=37

therefore

U coulbe between 48 and 37

Solve the system of equations by substitution. What is the solution for x?
Nostrana [21]

Answer:

There is no x value, as there is no solution

Step-by-step explanation:

we have

2x+y=1

Isolate the variable y

y=-2x+1 -----> equation A

4x+2y=-1 ---> equation B

Solve the system of equations by substitution

Substitute the equation A in the equation B and solve for x

4x+2(-2x+1)=-1

4x-4x+2=-1

2=-1 ------> is not true

therefore

The system has no solution

Equation A and equation B are parallel lines with different y-intercepts
