(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
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
This expression matches the 3rd choice.

Select the correct answer.
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.
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.

If 3x - 5y = 11 and 2x + 3y = 5, then what is the ratio of x to y?
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]

If 55% of a number is 132 and 25% of the same number is 60, find 80% of that number.
Answer:
192
Step-by-step explanation:
It is always wise to look carefully at the question to see what information is given, and what information you are asked for. You are given two different fractions of the same number, and you want the value of a third fraction of that number. That third fraction is the sum of the other two.
__
The value of 80% of the number will be the sum of 55% and 25% of the number.
n×80% = n×55% +n×25%
n×80% = 132 +60
n×80% = 192
80% of the number is 192.
_____
Additional comment
Your first clue that there may be something special about this problem lies in the fact that one fraction of a number is all you need in order to find any other fraction. Here, we're given two fractions (55% and 25%), so that is more information than we need. Why? Because it simplifies the problem to one of addition. No proportions need to be solved.
__
If you were interested, you could determine 100% of the number to be ...
132/n = 55/100 ⇒ n = 132(100/55) = 240
or
60/n = 25/100 ⇒ n = 60(100/25) = 240
Then ...
0.80n = 0.80(240) = 192 . . . . 80% of the number
Or, you could write proportions for the 80% value:
80%/55% = n/132 ⇒ n = 132(80/55) = 192 . . . . 80% of the number
80%/25% = n/60 ⇒ n = 60(80/25) = 192 . . . . 80% of the number

I HAVE GOTTEN THE ANSWER
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
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 kmWrite the perimeter of the triangle as a simplified expression.
