Step-by-step explanation:
If cde is a straight angle, de bisects gdh, m gde = (8x-1), m edh = (6x-15), and m cdf= 43, find each measure.
Answer:
x = 7°
<GDH = 112°
<FDH = 192°
<FDE = 135°
Step-by-step explanation:
If DE bisects <GDH this means that <GDE = <EDH
Given <GDE = (8x+1)° and <EDH = (6x+15)° then;
8x+1 = 6x+15
8x-6x = 15-1
2x = 14
x = 7°
Since <GDH = <GDE + <EDH
<GDH = 8x-1+6x+15
<GDH = 14x+14
<GDH = 14(7)+14
<GDH = 98+14
<GDH = 112°
For <FDH,
Note that sum of angle on a straight line is 180°
<FDH = <FDG + <GDE + <EDH
<FDH = <FDG + <GDH
<FDG = 180-(43+8x+1)
<FDG = 180-44-8x = 136-8x
<FDH = 136-8x+112
<FDH = 248-8x
<FDH = 248-8(7)
<FDH = 248-56
<FDH = 192°
For <FDE;
<FDE = <FDG + <GDE
<FDE = 136-8x+8x-1
<FDE = 135°
Bryant has 2 ¼ gallons of gas in his tank when he stops at a gas station. At the gas station he puts 4 2/6 gallons of gas in his car. When driving away, how many gallons of gas does he have in his car?
Answer:
[tex]\frac{79}{12}[/tex] or 6[tex]\frac{7}{12}[/tex] gallons of gas.
Step-by-step explanation:
First, you have to convert both of your mixed numbers into a improper fractions.
2 [tex]\frac{1}{4}[/tex] = 9/4
4 [tex]\frac{2}{6}[/tex] = 26/6
Second, find the greatest common multiple of the denominators of both. In this case, it would be 12.
Then find the number that the first improper fraction's denominator would be multiplied by to get the GCM. Multiply both the nominator and the denominator by that number.
4 would need to be multiplied by 3 to get 12. So we multiply 9/4 by 3/3. We would get 27/12.
Repeat that for the second fraction's denominator.
6 would need to be multiplied by 2 to get 12. So we multiply 26/6 by 2/2. We would get 52/12.
Then add both fractions together.
[tex]\frac{27}{12}+\frac{52}{12}[/tex] [tex]=\frac{79}{12}[/tex]
If you need to, simplify.
[tex]\frac{79}{12} = 6\frac{7}{12}[/tex]
Hope that helped!
List the angles in order from largest to smallest.
A) ∠C > ∠B > ∠A
B) ∠C > ∠A > ∠B
C) ∠B > ∠A > ∠C
D) ∠A > ∠C > ∠B
Answer:
A
Step-by-step explanation:
The largest angle will be the angle that is opposite to longest side.
Longest side is AB = 18 cm. So, opposite angle of side AB is ∠C
Sides from largest to smallest : AB > AC > BC
angles form largest to smallest: ∠C > ∠B > ∠A

The lengths of the legs of a right triangle are 8 inches and 9 inches. What is the length of the hypotenuse? Round to the nearest inch. Enter your answer in the box.
Right triangle, Pythagorean Theorem:
c² = a² + b²
a=8, b=9
c² = 8² + 9² = 64 + 81 = 145
c = √145 inches
That's the exact answer but they want us to ruin it with an approximation.
c ≈ 12.041594578792296 inches
Answer: 12
5x^2-25x=125 solve by completeing the square
Answer:
x = 10, -15
Step-by-step explanation:
We can start right away by dividing both sides of our equation by 5 to get the reduced form [tex]x^2-5x=25[/tex].
To "complete the square," or turn the left side of the equation into something we can factor into a perfect square, it helps to remember that for any binomial x - a:
[tex](x-a)^2=x^2-2ax+a^2[/tex]
To "complete" our square, we'll need to add an a² to either side of the equation. To find a, we can set 5x = 2ax and solve:
[tex]5x=2ax\\5/2=a\\25/4=a^2[/tex]
Let's add that a² to both sides and simplify!
[tex]x^2-5x+\frac{25}{4}=25+\frac{25}{4}\\\\(x-\frac{5}{2})^2=\frac{125}{4}\\\\x-\frac{5}{2}=\pm\sqrt{\frac{125}{4} } \\\\x=\pm\frac{25}{2}-\frac{5}{2}[/tex]
Now we're ready to solve for both value of x:
[tex]x=\frac{25}{2}-\frac{5}{2}=\frac{20}{2} =10\\\\x=-\frac{25}{2}- \frac{5}{2}=-\frac{30}{2} =-15[/tex]
So our solutions are x = 10 and x = -15
Answer:
x=5+5√5/2
Step-by-step explanation:
The sum of a number and its square is 42. Which equation can be used to find the two numbers for which this is true?
O x^2+ x = 42
OX^2 + 2x = 42
Ox^2 + x + 42 = 0
O X^2 + 2x + 42=0
The equation would be x² + x = 42 which represents "the sum of a number and its square is 42". The correct answer would be an option (A).
What is algebra?
Algebra is the analysis of mathematical representations, while logic is the manipulation of those symbols.
We have been given that the sum of a number and its square is 42.
Let's assume the required number would be x
According to the given question, translate the phrase into an algebraic form:
The number = x
The number's square = x²
Thus, the sum of a number and its square is 42 will be as:
⇒ number + number's square = 42
⇒ x + x² = 42
Therefore, the equation would be x² + x = 42 which represents "the sum of a number and its square is 42".
Hence, the correct answer would be option (A).

Write an equation of a line PERPENDICULAR to
y = 2x + 3 through (-2, 4).
Answer: y= -0.5+8
Step-by-step explanation:
Any line that is perpendicular to a line is the opposite and inverse.
Ex. for a line to be perpendicular to 2, the reverse would be -2 and the opposite is -1/2.
Now we need to focus on the b in y=mx+b.
To do that, we plug in 4 as y and -2 in x to find b.
4=2(-2)+b
4=-4+b
And we find that b is 8.
So in conclusion, y=-0.5+8

Mark, Jhon and Stephanie, three archers, are aiming at a target. Each of them has only one shot. Mark has 1/5 chance of hitting the bullseye, Jhon has 1/4 chance and Stephanie has 1/3 chance.
a. what are the chances of the bullseye being hit
b. what are the chances that if only one of them hit the bullseye, Mark was the one who hit it.
For A:
You add the probabilities to get the answer to A: = .75, or 3/4
Note that the probability of ALL THREE of them hitting would be 1/3 x 1/4 x 1/5.
For B:
2/3 and 3/4 is the probability of the other two people MISSING (the remainder of 1/3, 1/4)
1.0 = 100% chance to hit the target, so 1.0 x 2/3 x 3/4 = 1/2
Mark's chance of hitting is 1/5, so do 1/2 x 1/5, = 1/10

Keiko determined that the coordinate points (–4, 0), (–3, –1), and (2, –6) are solutions to the following system. y = − x − 4 y = x 2 + x − 12 Which coordinates from the solution set are reasonable solutions to the system of equations?
Answer:
only (-4,0) is a reasonable solution.
Step-by-step explanation:
In order to see which ones are reasonable we need to apply the points to the system and check if they make both equations valid at the same time.
y = -x - 4
y = x² + x - 12
For (-4, 0):
0 = -(-4) - 4 -> 0 = 4 -4 -> 0 = 0 (valid)
0 = (-4)² - 4 - 12 -> 0 = 16 - 16 -> 0 = 0 (valid)
For (-3, -1):
-1 = -(-3) -4 -> -1 = 3 -4 -> -1 = -1 (valid)
-1 = (-3)² -1 - 12 -> -1 = 9 -13 -> -1 = -4 (invalid)
For (2, -6):
2 = -(-6) - 4 -> 2 = 6 -4 -> 2 = 2 (valid)
2 = (-6)² -6 -12 -> 2 = 36 -18 -> 2 = 18 (invalid)
Therefore only (-4,0) is a reasonable solution.
Question 4 (3 points)
In the coordinate plane, what is the length of the line segment that connects points
at (0,-1) and (-7, -2)?
Enter your answer to the nearest hundredth.
Hint: No points will be awarded unless it is to the nearest hundreth. An example is
3.04.
Answer:
≈ 7.07
Step-by-step explanation:
Calculate the length using the distance formula
d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = (0, - 1) and (x₂, y₂ ) = (- 7, - 2)
d = [tex]\sqrt{(-7-0)^2+(-2+1)^2}[/tex]
= [tex]\sqrt{(-7)^2+(-1)^2}[/tex]
= [tex]\sqrt{49+1}[/tex]
= [tex]\sqrt{50}[/tex] ≈ 7.07 ( to the nearest hundredth )
