Answer:
Step-by-step explanation:
Because midpoints were used to make similar triangles we can say
AC=2(DE)
5x+12=2(9x-20)
5x+12=18x-40
-13x+12=-40
-13x=-52
x=4
AC=5x+12
AC=5(4)+12
AC=20+12
AC=32
Answer:
Step-by-step explanation:
DE = (1/2) * AC {Midpoint theorem}
[tex]9x - 20 =\frac{1}{2}(5x + 12)[/tex]
2(9x - 20) = 5x + 12
2*9x - 2*20 = 5x + 12
18x - 40 = 5x + 12
18x -5x - 40 = 12
13x - 40 = 12
13x = 12+40
13x = 52
x = 52/13
x = 4
AC = 5x + 12
= 5*4 + 12
= 20 +12
AC = 32

An architect is making a plan for a new circular playground. If the playground needs to be surrounded by a fence and the diameter of the playground is 25 meters, how much fencing needs to go up?
Answer:
78.54 m
Step-by-step explanation:
To obtain how much circular fence, we obtain the Circumference of the circular playground.
The Circumference of a circle, C = 2*pi*r
pi = 3.14 ; r = diameter / 2 = 25 /2 = 12.5 m
C = 2 * 3.14 * 12.5
C = 78.539816
Hence, the fencing which need to go up is ;
78.54 m

Lucas borrows $3,500 at 2% for 6 years. How much does he have to repay at the end of the loan total?
Answer:
$3941.57.
Step-by-step explanation:
Given,
Principal,P = $3,500
rate of interest,r = 2%
Time, n = 6 years
Now, the total amount Luca has to repay is:
[tex]A = P(1+\frac{r}{100})^n[/tex]
A is the total amount.
[tex]A = 3500\times (1+\frac{2}{100})^6\\A = $3941.57[/tex]
Hence, the total money he has to repay is $3941.57.
The points (-1,r) and (11, -1) lie on a line with slope -3/4
Find the missing coordinate r.
Answer:
8
Step-by-step explanation:
y = (-3/4)x + c
Sub (11,-1) into the equtaion
-1 = (-3/4)(11) + c
c = 29/4
y = (-3/4)x + 29/4
when x = -1,
y = (-3/4)(-1) + 29/4
y = 8
r = 8

A boat attempts to sail due east at 15km/h, but is taken off course by a current of 5 km/h flowing in the southwest direction. Find the resultant speed of the boat and the bearing on which it travels.
Answer:
10 km / hr
Step-by-step explanation:
Speed of boat = 15 km /hr
Speed of stream = 5km /hr .
Since both are acting opposite to each other . The the resultant speed with which it travels = 15 - 5 = 10 km/hr

Question: What is the value of x in the diagram.
Answer:
A. X = 30º
Step-by-step explanation:
The angle labeled x & the right angle are vertical angles to the one labeled 120º.
Therefore:
X + 90 = 120
Solve for x:
X + (90-90) = 120 - 90
X = 30

There are different ways to draw a circle. To construct a circle through points X, Y, and Z, one must:
Steps to Construct a Circle Through Points x, y, and zSetting up the Points by drawing your points A, B, and C in any given position of your choice, know if your points are noncollinear and then draw two line segments in the space between any two sets of points. Drawing Perpendicular Bisectors: This can be done by Drawing an arc centered at the first endpoint of the first line segment, then draw another arc at the center of the second endpoint, then Draw a line that links the intersections of the arc and lastly draw the perpendicular bisector of the second line segment. Draw the Circle: Through the use of a Set the compass width to the circle’s radius, move the compass in a 360 degrees and erase the line segments, arcs, and perpendicular bisectors.Learn more about constructing a circle from
