In ΔCDE, \text{m}\angle C = (4x-16)^{\circ}m∠C=(4x−16) ∘ , \text{m}\angle D = (6x-1)^{\circ}m∠D=(6x−1) ∘ , and \text{m}\angle E = (4x-13)^{\circ}m∠E=(4x−13) ∘ . Find \text{m}\angle C.M∠C.
Answer:
m∠C = 44°
Step-by-step explanation:
In ΔCDE,
m∠C=(4x−16) ∘
m∠D=(6x−1) ∘
m∠E=(4x−13) ∘ .
The sum of angles in a triangle = 180°
Step 1
We solve for x
m∠C + m∠D + m∠E
(4x−16)° + (6x−1)° + (4x−13)° = 180°
4x - 16 + 6x - 1 + 4x - 13 = 180°
4x + 6x + 4x -16 - 1 - 13 = 180°
14x - 30 = 180°
14x = 180+ 30
14x = 210
x = 210/14
x = 15
Step 2
Find m∠C
m∠C = (4x−16)°
m∠C = (4 × 15 - 16)°
m∠C = (60 - 16)°
m∠C = 44°
help with this bounds question please
Answer: 6.68km/litre
Step-by-step explanation:
Distance(d) = 187km ( to 3 significant figures)
Petrol(p) = 28litres ( to 2 significant figures)
A number, x, rounded to 1 significant figure is 200
Write down the error interval for x
Calculating the lower and upper bound for both 'd' and 'p'
Upper bound 'd' = 187.5km
Lower bound 'd' = 186.5km
Upper bound 'p' = 28.5km
Lower bound 'p' = 27.5km
Therefore,
Petrol consumption (C) = d/p
Upper C = 187.5 / 28.5 = 6.57894
Lower C = 186.5 / 27.5 = 6.781818
Accuracy answer for C = (6.57894 + 6.781818) / 2 = 6.680379
= 6.68km/ litre ( to 3 significant figures)
To achieve a reasonable level of accuracy, the upper and lower bounds of P and D was used to calculate C, which was then averaged.
Using 3 significant figures ensure that we capture the C better, instead of early rounding.

The radius of the circle
[tex]r = \frac{d}{2} = \frac{11}{2} = 5.5[/tex]
Circumference of the circle
= 2πr
= 2×3.14×5.5
= 34.54
Final answer:-
Circumference of the circle = 34.54 inches

PLZ HELP IM BEGGING
Answer:
-x+y= -14 (get this equation to where you can easily plug it in for a variable)
y= x -14
5x +6y =26 (plug the value above in for y and then solve)
5x + 6 (x-14) = 26 (use the distributive property)
5x +6x - 84 = 26 (combine like terms on the left side)
11x - 84 =26 (add 84 to both sides)
11x = 110 (divide both sides by 11 to isolate the x-variable)
x= 10 (this is the value for x. plug it into the easier equation and solve)
-(10) +y = -14
y= -4
(10, -4) (this is the solution for the system of equations)

Step-by-step explanation:
p1=(2,4) and p2=(5,6)
use slope formula to find the slope
[m=y2-y1 / x2-x1)]
m=6-4 / 5-2
m=2 / 3
use point-slope formula [y-y1=m(x-x1)] with either given point and work but since they have a 5 and a 6 in the their answer use p2
y-6=2/3(x-5)

Answer:
+ 5°
Step-by-step explanation:
Given,
Good morning temperature = -15°
Raise in temperature = 20°
Afternoon temperature = -15° + 20°
= + 5°
Hence, temperature in after noon is equal to + 5°.
Tyler's grandma purchased a savings bond for him when he was born. The bond was bought for $500.00. The value of the savings bond increases by 5% a year. Tyler's grandma wants Tyler to use it for college, so he is not allowed to touch it until he is 18.
How much money will Tyler have when he is 18
Answer: 950 dollars
Step-by-step explanation:
5% of 500 dollars is 25 dollars, so since 5% is 25 dollars, multiply that by how many years he can have it (18). So 18 * 25 = 450. 450 added to the starting 500 dollars is 950 dollars. Your welcome, I'm new so glad I could help.
Indicate whether the measures 3.1, 4.8, and 10.2 can be the side lengths of a triangle. If they can, classify the triangle.
The measures 3.1, 4.8, and 10.2 cannot be the side lengths of a triangle.
What is triangle inequality?"It states that the sum of any two sides must be greater than the third side."
For given question,
we have been given the measures 3.1, 4.8, and 10.2
We need to check whether given measures can be the side lengths of a triangle.
First we check whether the given measures obey triangle inequality or not.
3.1 + 4.8 = 7.9
7.9 < 10.2
This means, the measures 3.1, 4.8, and 10.2 do not obey triangle inequality
Therefore, the measures 3.1, 4.8, and 10.2 cannot be the side lengths of a triangle.

Answer:
n = 0.8
Step-by-step explanation:
3n + 3 = 5.4
-3 form each side
3n=2.4
÷3 for each side
n=0.8
Answer:
0.8
Step-by-step explanation:
3(n+1)=5.4
Divide both sides by 3
3(n+1)/3 = 5.4/3
simplify
n+1=1.8
subtract 1 from both sides
n+1-1=1.8-1
N=0.8
How are fractals developed
Answer:
Fractals are infinitely complex patterns that are self-similar across different scales. They are created by repeating a simple process over and over in an ongoing feedback loop. ... Abstract fractals – such as the Mandelbrot Set – can be generated by a computer calculating a simple equation over and over.
Step-by-step explanation:
Which statement about this product is true? 0.44×(−5 3/4)
It is equal to 0 because 0.44 rounded to the nearest whole number is 0, and 0 times any number is 0.
It is equal to −534 because 44 is equal to 1, and 1 times any number equals that number.
It is greater than −3 because 0.44×534 is less than 12×6.
It is less than −534 because multiplying by a number less than 1 gives a smaller number.

-3x+7y=5x+2y Please HELP Complete the missing value in the solution to the equation.
(-5,_)
Answer:
(-5, -8); the missing value is -8
Step-by-step explanation:
First, you need to simplify the given equation to isolate y
1: -3x + 7y = 5x + 2y (Given)
2: 7y = 8x + 2y (Add 3x to both sides)
3: 5y = 8x (Subtract 2y from both sides)
4: y = 8/5x (Divide both sides by 5)
Now, you can use this to solve for the missing y in value set (-5, y)
where y = 8/5x and x = -5,
y = 8/5(-5)
y = -8
so, the missing value is -8
