Step-by-step explanation:
<ADC is 90
in triangle ACD
<CAD + ACD + ADC = 180
<CAD + ACD + 90 = 180
<CAD + ACD = 90
hence CAD AND ACD MAKES complementary angle(90)
Angle sum property
<ADC is 90°
As
Sum of angles in triangle is 180°
<CAD+<ACD=180-90=90°Hence they are complementary

Max made a journey of 700km partly by train and partly by bus.He started his journey at 8.00am. by train which travelled at 50km/hr. After alighting from the train, he took a lunch break of 30 minutes. He then continued his journey by bus which travelled at 75km/hr.The whole journey took 11.75hours. Determine the distance travelled by bus.
so this is the answer
time taken by the train=x
time taken by the bus=y
subtract 30 minutes from the total time taken..hence x+y=10.75
form an equation
x+y=10.75
50x+75y=700
y=6.5
75×6.5=487.5
Answers
Answer:
487.5 km
Step-by-step explanation:
Let :
time taken by the train = xtime taken by the bus = ySolving
Subtract 30 minutes from the total time taken.Hence x + y = 10.75Forming an equation
x + y = 10.7550x + 75y = 700y = 6.575 × 6.5 = 487.5 kmY=5x+6; x=-2 find the value of y for the given value of x

A pew research poll asked u.s. adults whether fathers today were doing as good a job of fathering as fathers of 20-30 years ago. the table shows their responses. if we select a respondent at random from this sample, what is the probability that the person responded "same" or "better"?
Answers
Using it's concept, it is found that there is a 0.4901 = 49.01% probability that the person responded "same" or "better".
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
Researching the problem on the internet, it is found that 424 + 566 = 990 out of 2020 respondants said that they were doing the same or better, hence:
p = 990/2020 = 0.4901
0.4901 = 49.01% probability that the person responded "same" or "better".

(05.01 LC) which equation can be used to calculate the area of the shaded triangle below? A. 2(10+6) = 32
B.1 over 2(10 +6) = 8
C. 1 over 2(10 x 6) = 30
D. 2(10 x 6) = 120
Answers
Answer:
(c) 1/2(10×6) = 30
Step-by-step explanation:
The formula for the area of a triangle is ...
A = 1/2bh
The shaded triangle has a base of 10 feet and a height of 6 feet. Using these numbers in the formula, the area in square feet is ...
A = 1/2(10×6) = 30 . . . . square feet

If 3x - 5y = 11 and 2x + 3y = 5, then what is the ratio of x to y?
Answers
Answer:
-58/7
Step-by-step explanation:
Alright so this is a system of equations. First we'll solve the system, and then find the ratio afterwards.
[tex]3x-5y = 11\\2x+3y =5\\[/tex]
Isolate for y on both.
[tex]2x + 3y = 5\\3y = 5-2x\\y = \frac{5-2x}{3}[/tex]
and
[tex]3x - 5y = 11\\-5y = 11-3x\\y = \frac{11-3x}{-5}[/tex]
Set both equations equal to each other:
[tex]\frac{11-3x}{-5} = \frac{5-2x}{3}\\ \\\frac{3(11-3x)}{-5} = 5-2x\\ \\3(11-3x) = -5(5-2x)\\\\33 - 9x = -25 + 10x\\33 = -25 + 19x\\58 = 19x\\\frac{58}{19} = x[/tex]
We've got x, now let's solve for y:
[tex]y = \frac{11-3x}{-5} = \frac{11-3(\frac{58}{19}) }{-5}[/tex]
Now we got both x and y, and what they equal.
[tex]y = \frac{-7}{19}\\[/tex]
[tex]x = \frac{58}{19}[/tex]
The ratio of x to y, is essentially [tex]\frac{x}{y}[/tex]. So we will calculate that.
[tex]\frac{\frac{58}{19} }{\frac{-7}{19} } = \frac{58}{19} * \frac{19}{-7} = \frac{-58}{7}[/tex]

mel is teaching travis how to use a compass and a straightedge to construct a square inscribed in a circle. he tells travis to begin by using a
straightedge to draw any chord of the circle and label it wx. next, his instructions are to use the tools to construct a chord that is a
perpendicular bisector of wx and label it yz. finally, he directs travis to use a straightedge to draw the four chords that make up the square: wy
yx, xz, and zw.
what is the first error, if any, mel made in his instructions to travis?
oa mel's instructions contain no errors.
ob. chord wx must be a diameter of the circle,
oc chord yz is found by constructing a segment congruent to wx.
od the four chords that make up the square are the perpendicular bisectors of wx and yz.
ое. chord wx must be congruent to the radius of the circle.
Answers
Answer:
I think the answer is B
Step-by-step explanation:
The error which is made by Mel in drawing square in the circle is that thefour chords that ob , chord wx must be a diameter
What is square?A square is a 2 dimensional figure having four sides and four angles which are equal to 90°. All sides of square are always equals to each other.
How to draw a square in a circle?First draw a circle in which we want to draw such square.
Next draw a chord in the circle.
From one end, draw a straight line connecting a point on the circle and end point of the chord in such a way that the line and chord are perpendicular to each other.
Next draw another line also from the end of line formed in second step.
Lastly draw a line from the other end of chord and join it with the line we have drawn lastly.
In this way we will get square in circle.
