David found a vintage watch his father lost 38 years ago. The watch’s date showed that it had worked for over two years after his father lost it. When David found the watch, it was 3 times as old as when his father lost it. How old was the watch when David’s father lost it?
Answers
According to the given information, the watch worked for over two years after his father lost it. So, the total age of the watch becomes "x + 2" years.
When David found the watch, it was 3 times as old as when his father lost it. This means the age of the watch at that time was 3 times "x".
Since the total age of the watch when David found it was the sum of the age when his father lost it and the additional years it worked, we can set up the following equation:
(x + 2) = 3x
Now, let's solve the equation to find the value of "x" (the age of the watch when David's father lost it):
x + 2 = 3x
2 = 3x - x
2 = 2x
x = 1
Therefore, the watch was 1 year old when David's father lost it.
Answer:
Step-by-step explanation:
Hey there,
Here's my reasoning regarding the problem:
Let's assume that the watch at the time it was lost was x years old.
When it was picked it was 3 times as old as it was when it was lost therefore it's currently 3x. The time between when it was lost and when it was found is 38 years. We can break this down into a simple algebraic formula:
3x - x = 38
2x = 38
x = 19

C X2+ (y - 4)2 = 117
D (x 4)2 + 2 = 17
Answers
The equation of the circle with the center (0, 4) and a point (-1, 8) on the circle is x² + (y - 4)² = 17.
What is the equation of the circle?The standard form equation of a circle with center (h, k) and radius r is:
(x - h)² + (y - k)² = r²
Given that the center is (0, 4) and a point (-1, 8) is on the circle, we can calculate the radius using the distance formula:
[tex]r = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2} \\\\r = \sqrt{(-1 - 0)^2+(8-4)^2} \\\\r = \sqrt{(-1 )^2+(4)^2} \\\\r = \sqrt{1+16} \\\\r = \sqrt{17}[/tex]
Now, let's plug the values of the center (0,4) and the radius √17 into the standard form of the equation of a circle:
(x - h)² + (y - k)² = r²
(x - 0)² + (y - 4)² = (√17)²
Simplify
x² + (y - 4)² = 17
Therefore, the equation of the circle is x² + (y - 4)² = 17.

Answers
The area of the composite figure is 81 units².
Given is a composite figure with two semicircles of diameter 4 units attached to the both ends of a rectangle with length 14 units,
We need to find the area of the composite figure,
Calculating the areas of each component separately and adding them together will yield the area of the composite figure.
Area of a rectangle = length × width
Area of a semicircle = π × radius²
Here the width of the rectangle and the diameter of the semicircle are same.
So, the area of the figure =

One of the plans involves prescription drug coverage. The employee estimates that the entire family will fill 10 prescriptions per month, totaling $1,250. The employee has two options to choose from:
Option A: $94 monthly premium; 80% coverage for all prescription costs
Option B: $42 monthly premium; 75% coverage for first $500 in prescription costs, then 85% coverage for all prescription costs over $500
Which option would result in the highest overall cost for the employee, and by how much?
Option A has the highest overall cost by $64.50.
Option B has the highest overall cost by $64.50.
Option A has the highest overall cost by $106.50.
Option B has the highest overall cost by $106.50
Answers
Where the above is given, Option B has the highest overall cost by $685.50.
How is this so ?To find the option would result in the highest overall cost for the employee, we need to calculate the total cost under each option.
Option A
Monthly premium: $94
Prescription coverage: 80%
Total cost under Option A
Monthly premium: $94
Prescription costs covered: 80% of $1,250
= $1,000 (since the employee estimates filling 10 prescriptions totaling $1,250)
Employee's portion of prescription costs: 20% of $1,250 = $250
Overall cost = $94 + $250 = $344
Option B
Monthly premium $42
Prescription coverage 75% for first $500, then 85% for costs over $500
Total cost under Option B
Monthly premium: $42
Prescription costs covered up to $500: 75% of $500 = $375
Prescription costs covered over $500is
85% x ($1,250 - $500)
= 85% of $750
= $637.50
Employee's portion of prescription cost is
($1,250 - $375) + ($750 - $637.50)
= $875 + $112.50
= $987.50
Overall cost: $42 + $987.50 = $1,029.50
Hence Option B has the highest overall cost by $1,029.50 - $344 = $685.50.

Answer: 110 degrees
Step-by-step explanation: If we have a triangle with an exterior line sticking out, we can determine the measure of the exterior angle by applying the Exterior Angle Theorem. According to the theorem, the measure of an exterior angle of a triangle is equal to the sum of the measures of the two non-adjacent interior angles.
In this case, the two known interior angles are 65 degrees and 45 degrees. To find the measure of the exterior angle, x, we add these two angles:
x = 65 degrees + 45 degrees
x = 110 degrees
[tex]\large \maltese \:{ \underline { \underline{ \pmb{ \sf{SolutioN }}}}} : -[/tex]
we have given ,
∠ A = 65°∠ B = 45°∠ C = ?? ( to be calculated)★ According to Angle sum property of triangle, the sum of interior angles of a triangle is 180°.
➝ ∠ A + ∠ B + ∠ C = 180°
➝ 65° + 45° + ∠ C = 180°
➝ 110° + ∠ C = 180°
➝ ∠ C = 180° - 110°
➝ ∠ C = 70°
Now,
★ Calculating for x :-
↝ ∠ C + x = 180°
↝ 70° + x = 180°
↝ x = 180° - 70°
↝ x = 110°
Hence, The value of x will be 110°.

Answers
Answer:
x = 120 , y = 50
Step-by-step explanation:
1 and 140° are a linear pair and sum to 180° , that is
1 + 140 = 180 ( subtract 140 from both sides )
1 = 40
the sum of the 3 angles in Δ ABE = 180° , so
∠ BAE = 180° - ( 80 + 40)° = 180° - 120° = 60°
∠ BAE and ∠ CDE are same- side interior angles and sum to 180° , that is
x + 60 = 180 ( subtract 60 from both sides )
x = 120
the sum of the 3 angles in Δ CDE = 180° , that is
10 + x + 2 = 180
10 + 120 + 2 = 180
130 + 2 = 180 ( subtract 130 from both sides )
2 = 50
AED is a straight line , then
y + 80 + 2 = 180
y + 80 + 50 = 180
y + 130 = 180 ( subtract 130 from both sides )
y = 50

In the situation you described, there are 4 large tables with an equal number of guests seated at each table. Let’s represent the number of guests at each large table with the variable n. There are also 8 late-arriving guests seated at a smaller table. The total number of guests at the dinner is 48.

LESSON 17 SESSION 3
4 Ms. Duda's class is hanging 500 red lanterns around the
school for Lunar New Year. Before lunch, the class hangs
100 of the lanterns.
PART A Draw a model to show what percent of 500 lanterns
the class hangs before lunch.
Answers
The model should visually represent that Ms. Duda's class hung 100 lanterns before lunch, which is 20% of the total 500 lanterns.
To draw a model showing what percent of 500 lanterns Ms. Duda's class hangs before lunch, we can use a rectangular bar model.
Draw a rectangular bar to represent the total number of lanterns, which is 500. Label it as "Total Lanterns."
Divide the rectangular bar into two parts. One part should represent the number of lanterns hung before lunch, which is 100. Label this section as "Lanterns Before Lunch."
Calculate the percentage of lanterns hung before lunch by dividing the number of lanterns hung before lunch by the total number of lanterns and multiplying by 100. In this case, (100/500) * 100 = 20%.
Draw an arrow pointing to the "Lanterns Before Lunch" section, and write "20%" next to it to represent the percentage.
The model should visually represent that Ms. Duda's class hung 100 lanterns before lunch, which is 20% of the total 500 lanterns.
