Answer:
6:6=x
7:16=y
8:20=z
Step-by-step explanation:
For 6, since BD is a perpendicuar bisector, that means 15x=90. Divide 90 by 15 and you get 6
for 7, if bd is a angle bisector, you can set 3y=48. divide 48 by 3 and you get 16
for 8, since Bd is a median, you can set 2z-3=z+17. Isolate the variable and you will get 2z-z=17+3. Add like terms together and you get z=20
Just so you know, a perpendicular bisector will make both angles equal to 90, an angle bisector make both angles equal to each other, and medians make it so that it hit a line in the center therefor you can set both sides of the line to be equal

Find the area of the shape below:
Answers
Answer:
Area of shape = 120 m²
Step-by-step explanation:
Given:
Height of triangle joint = 4 m
Base = 12 m
Width = 8 m
Find:
Area of shape
Computation:
Area of shape = Area of triangle + Area of rectangle
Area of shape = (1/2)(Base x height) + [Base x Width]
Area of shape = (1/2)(12 x 4) + [12 x 8]
Area of shape = 24 + 96
Area of shape = 120 m²

find the length of each bolded arc. Round to the nearest hundredth.
Answers
Answer:
Length of the bold arc = 72.63 ft
Step-by-step explanation:
Length of the arc = [tex]\frac{\theta}{360}(2\pi r)[/tex]
Here, θ = angle subtended by the arc at the center
r = Radius of the circle
Since, angle subtended by the bold arc at the center = 360 - 73
= 287°
And radius of the circle 'r' = 14.5 ft
By substituting these values in the formula,
Length of the bold arc = [tex]\frac{287}{360}\times (2\pi)(14.5)[/tex]
= 72.632
≈ 72.63 ft
Therefore, length of the bold arc = 72.63 ft

Line M is represented by the equation -2/3+8. Line W is perpendicular and passes through the point (4,3)
Answers
Answer:
y= -3/2x+9
Step-by-step explanation:
Well we have to know that to find a line perpendicular to a given line, you have to have opposite slopes. So that makes the equation begin as y=-3/2x because it's opposite of y=2/3x. Then we have to make sure it goes through the point (4,3). To do that, I tweaked the numbers in my graphing calculator and it worked with 9! So the equation is y= -3/2x+9

After 8 weeks on a fitness program, mrs.Honaker can job 30 miles. Her average mileage gain has been 2 miles per week. Write an equation in slope intercept form to model this scenario.
Answers
Answer:
y = 2x + 14
Step-by-step explanation:
Equation in slope intercept form:
y = mx + c
From the scenario above ;
y = total miles = 30
Average mile gain per week = slope (m) = 2
Number of weeks (x) = 8
We can obtain intercept, c :
30 = 2(8) + c
30 = 16 + c
30 - 16 = c
14 = c
Hence,
Equation goes thus ;
y = 2x + 14

How I did this, the initial investment is y intercept AKA the value of y at x=0, to get percentile growth, I did year 0/ year 1 and got 0.94 or 94%, but you have to subtract that from 1 which gives you 0.06 or 6%, and to find value of investment after 10 years, I first did 6% growth per year multiplied by 10 years which gives you 60%, then I multiplied 500(1.6) and got 800.

B. 5x+y=8
C. 3x+2y=9
D. 3x−5y=−12
Answers
Answer:
5x + y = 8
Step-by-step explanation:
Given the equations:
x+3y=10 ____ (1)
2x−y=−1 ____ (2)
Multiply (2) by 2
2(2x - y = - 1) = 4x - 2y = - 2
4x - 2y = - 2 - - - (3)
Add (1) and (3)
4x - 2y = - 2
x + 3y = 10

Answers
Answer:
35.09
Step-by-step explanation:
From the question given above, the following data were:
Opposite = 12
Hypothenus = X
Angle θ = 20 °
The value of x can be obtained by using sine ratio as illustrated below:
Sine θ = Opposite / Hypothenus
Sine 20 = 12 / X
0.342 = 12 / X
Cross multiply
0.342 × X = 12
Divide both side by 0.342
X = 12 / 0.342
X = 35.09
Thus, the value of X is 35.09
