[tex]m\angle B= 41^{\circ},[/tex] [tex]m\angle F= 70^{\circ},[/tex] [tex]m\angle H = 61^{\circ},[/tex] [tex]m\angle K= 56^{\circ}.[/tex]
Step-by-step explanation:
Step 1:
The total of the angles in any triangle is 180°.
So to determine the third angle of the given triangles, we subtract the sum of the other two sides from, 180°.
The third angle = 180° - (the first angle + the second angle).
Step 2:
For triangle ABC,
[tex]m\angle B=180^{\circ}-(\angle A+\angle C)[/tex],
[tex]m\angle B=180^{\circ}-(83^{\circ} + 56^{\circ}) = 180^{\circ} - 139^{\circ} = 41^{\circ}.[/tex]
So [tex]m\angle B= 41^{\circ}.[/tex]
For triangle DEF,
[tex]m\angle F=180^{\circ}-(\angle D+\angle E)[/tex],
[tex]m\angle F=180^{\circ}-(61^{\circ} + 49^{\circ}) = 180^{\circ} - 110^{\circ} = 70^{\circ}.[/tex]
So [tex]m\angle F= 70^{\circ}.[/tex]
Step 3:
For triangle GHI,
[tex]m\angle H=180^{\circ}-(\angle G+\angle I)[/tex],
[tex]m\angle H=180^{\circ}-(49^{\circ} + 70^{\circ}) = 180^{\circ} - 119^{\circ} = 61^{\circ}.[/tex]
So [tex]m\angle H = 61^{\circ}.[/tex]
For triangle JKL,
[tex]m\angle K=180^{\circ}-(\angle J+\angle L)[/tex],
[tex]m\angle K=180^{\circ}-(83^{\circ} + 41^{\circ}) = 180^{\circ} - 124^{\circ} = 56^{\circ}.[/tex]
So [tex]m\angle K= 56^{\circ}.[/tex]
The bill for dinner was $73.57 you left $11.43 for the tip what percentage of the original bill was the tip ? Round to the nearest whole percent
Answer:
16%
Step-by-step explanation:
Percentage of the tip is the tip divided by the original bill and the result multiplied by 100%
That’s
$11.43/$73.57 x 100%
0.1554 x 100%
15.54
16%
The tip was 16% of the original bill
The tip was about 16% of the total bill. This was calculated by dividing the tip amount by the total bill, multiplying by 100 to get a percentage, and then rounding to the nearest whole percent.
Explanation:To find out what percentage the tip was of the original bill, you would divide the amount of the tip by the total bill before the tip, and then multiply that number by 100 to get a percentage. Here's how you would calculate it in this case:
First, divide $11.43 (the amount of the tip) by $73.57 (the original bill). This will give you the decimal 0.1554285.Multiply this decimal by 100 to convert it to a percentage. This will give you 15.54285. Round this number to the nearest whole percent. The rounded percentage in this case is approximately 16%.So, the tip was about 16% of the total bill.

Answer:
NF = 16 units
Step-by-step explanation:
The in-center of a triangle is a point inside the triangle and equidistant from the three sides of the triangleIt is the center of the circle which touch the three sides of the triangle (each side of a triangle is tangent to the circle and the segments drawn from it to the points of tangent are radii of the circle)∵ N is the in-center of ΔABC
∴ N is equidistant from the sides AB, BC and CA
- That means the perpendicular segments from N to AB, BC
and AC are equal
∴ ND = NE = NF
∵ ND = 6x - 2
∵ NE = 3x + 7
- Equate them to find x
∴ 6x - 2 = 3x + 7
- Subtract 3x from both sides
∴ 3x - 2 = 7
- Add 2 to both sides
∴ 3x = 9
- Divide both sides by 3
∴ x = 3
- Substitute the value of x in ND to find its length
∵ ND = 6(3) - 2 = 18 - 2
∴ ND = 16 units
∵ ND = NE = NF
∴ NF = 16 units

Find the equation of the line that passes through the points (-800, 200) and (-400, 300).
Answer:
y=1/4x+400
Step-by-step explanation:
Slope=Rise/Run=(300-200)/(-400-(-800))=100/400=1/4
Now we have the slope, making our equation:
y=1/4x+b
We need b, the y-intercept, which we can use any ordered pair to plug in:
200=1/4(-800)+b
200=-200+b
400=b
So the equation that passes through the points (-800, 200) and (-400, 300) is: y=1/4x+400
The equation of line that passes through the points P(-800, 200) and Q(-400, 300) is y = x/4 + 400.
What is the general equation of straight line?
The general equation of straight line is -
y = mx + c
Given is a line that passes through the points P(-800, 200) and
Q(-400, 300).
First we will find the slope of the line -
m = (y₂ - y₁)/(x₂ - x₁)
m = (300 - 200)/(-400 + 800)
m = 100/400
m = 1/4
Now, the line passes through the point Q(-400, 300). Therefore -
300 = (1/4) x (- 400) + c
300 = - 100 + c
c = 400
The final equation of the line will be -
y = x/4 + 400
Therefore, the equation of line that passes through the points P(-800, 200) and Q(-400, 300) is y = x/4 + 400.

A solution to the equation x^3 −10x=100 using the trial and improvement method is approximately x=5.3 (rounded to 1 decimal place).
let's use the trial and improvement method to find a solution for the equation
x^3 −10x=100.
Start with a reasonable guess for x. In this case, it's often helpful to start with small integers.
Substitute the guess into the equation and see if it satisfies the equation.
Let's try
5^3 −10×5=125−50=75
The result is not equal to 100. Since the result is less than 100, we need to increase our guess.
Let's try
6^3 −10×6=216−60=156
The result is still not equal to 100. Since the result is now greater than 100, we need to decrease our guess.
Let's try
5.5^3 −10×5.5=166.375−55=111.375
This result is still greater than 100, so we need to try a smaller value.
5.2^3 −10×5.2=140.608−52=88.608
Now, this result is closer to 100. We can continue to refine our guess.
Let's try
5.3^3 −10×5.3=150.097−53=97.097
This result is getting closer to 100. We can keep refining our guess, but for the sake of brevity, let's stop here.
So, a solution to the equation x^3 −10x=100 using the trial and improvement method is approximately x=5.3 (rounded to 1 decimal place).

Roxanne has $3,000 that she plans to invest into an account that earns 7% simple interest.Assuming she makes no additional deposits or withdrawals, how much interest will Roxanne earn after 15 years? *
Answer:
$3150
Step-by-step explanation:
I = P • R • T
Intrest Equals Principal Amout times Rate of Intrest times Amount of Time
P is our Principal amount of $3,000
R is our Rate of 7%
T is the time span of years
Now if we plug in the values and solve the equation we get $3150 dollars in intrest.
Final answer:
Roxanne will earn $3,150 in interest after 15 years.
Explanation:
To calculate the interest Roxanne will earn, we can use the formula:
Interest = Principal x Rate x Time
Where Principal is the initial amount invested, Rate is the interest rate, and Time is the number of years.
Plugging in the given values, we get:
Interest = $3,000 x 0.07 x 15
Interest = $3,150
Therefore, Roxanne will earn $3,150 in interest after 15 years. This implies that Roxanne will accumulate $3,150 in interest after 15 years, illustrating the straightforward application of the interest formula to quantify the financial growth derived from the initial investment over the specified period.

The HCF of two numbers is 75.The LCM of the two numbers is 1500.The one number out of the two numbers is 300.
Let, the another number be assumed as 'x'.
The first number = 300 and the second number = x.
To find the number x :
The HCF × LCM = product of two Numbers is a logic to used to find the unknown number.
We know the values of HCF = 75 , LCM = 1500 and one number = 300 and the second number is x.
Therefore, substituting those values in the above formula, we get

⇒ 1125 / 3 = x
⇒ 375 = x
Therefore, the second number is 375.
Which statements are true about the components of a circle? Check all that apply.
The radius is half the length of the diameter.
The circumferences is triple the radius.
The circumference is the perimeter of a circle.
To find the circumference, multiply it by the diameter.
The diameter is triple the length of the radius.
The radius of a circle is half the length of the diameter, and the circumference is the perimeter of the circle. However, the circumference is not triple the radius, and the diameter is not triple the length of the radius.
Explanation:In the context of Mathematics, particularly geometry, the following statements are indeed true about the components of a circle:
The radius is half the length of the diameter. This is because the radius of a circle is defined as the distance from the center of the circle to its edge, while the diameter is the distance across the circle passing through the center. The circumference is the perimeter of the circle. This perimeter is also called the circumference in the context of circles, as it is the length around the edge of the circle.However, the statements that the circumference is triple the radius, to find the circumference multiply it by the diameter, and the diameter is triple the length of the radius, are incorrect. The circumference of a circle is calculated as 2πr (two times the radius times Pi), and the diameter is twice the length of the radius, not triple.
