HELP How Would I Find C? Would I Have To Subtract 180 From 50??

Answers

Answer 1

Answer:

m∠C = 115°

Step-by-step explanation:

DE≈DF

ΔDEF is an isosceles triangle ∴ m∠DEF = m∠DFE = 1/2 (180-50) = 65

∴ m∠DFB = 180 -65 = 115

∵ DCBF is a parallelogram m∠DFB = m∠DCB = 115°

Stacy is playing hide-and-seek with Austin and Christopher. Austin is hiding 12 meters south of Stacy, and Christopher is hiding 5 meters east of Austin. How far apart are Stacy and Christopher?

Answers

Answer:

Stacy is 13 meters apart from Christopher.

Step-by-step explanation:

Given:

Austin is hiding 12 meters south of Stacy.

Christopher is hiding 5 meters east of Austin.

To find distance between Stacy and Christopher.

Solution:

From the given data, we will trace the positions of each as shown in the figure below.

We find that the distance between Stacy and Christopher is the hypotenuse side of a right triangle formed by their positions.

By Pythagorean theorem:

[tex]Hypotenuse^2=Leg1^2+Leg2^2[/tex]

From the triangle:

Leg 1 = 5 meters

Leg 2= 12 meters

Plugging in the values.

[tex]Hypotenuse^2=5^2+12^2[/tex]

Simplifying.

[tex]Hypotenuse^2=25+144[/tex]

[tex]Hypotenuse^2=169[/tex]

Taking square root both sides.

[tex]\sqrt{Hypotenuse^2}=\sqrt{169}[/tex]

[tex]Hypotenuse=13[/tex] meters

Thus, distance between Stacy and Christopher = 13 meters

Stacy and Christopher are 13 meters apart. This was calculated using the Pythagorean theorem to find the hypotenuse of a right triangle with sides 12 meters and 5 meters.

To determine the distance between Stacy and Christopher, we need to view Stacy's location and the hiding places of Austin and Christopher as points on a grid in which Stacy is at the origin. Since Austin is hiding 12 meters south of Stacy, we can consider him to be at point A(0, -12). Christopher is hiding 5 meters east of Austin, this makes him at point C(5, -12).

Now, to find the distance between Stacy and Christopher, we'll use the Pythagorean theorem which says that in a right-angled triangle, the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides. This can be written as:

C² = A² + B²

Where C is the hypotenuse, A and B are the other two sides of the triangle. In this case, A is the distance south (12 meters) and B is the distance east (5 meters). Thus,

C² = 12² + 5²

C² = 144 + 25

C² = 169

C = √169

C = 13 meters

Therefore, Stacy and Christopher are 13 meters apart.

What is the prescribed dosage of a certain medicine for a child 4 years old, if the adult dosage of the medicine is 180 milligrams? Round to the nearest whole number

Answers

Answer:

40 mg

Step-by-step explanation:

Given,

The prescribed dosage the medicine for an adult = 180 milligrams,

Since, the minimum age of an adult = 18 years,

So, the prescribed dosage of the medicine for 18 years old person = 180 milligrams,

Thus, the ratio of prescribed dosage of medicine ( in mg ) and age of person ( in years ) = [tex]\frac{180}{18}[/tex]

Suppose prescribed dosage of a certain medicine for a child 4 years old is x mg,

So, ratio of prescribed dosage of medicine and age = [tex]\frac{x}{4}[/tex]

[tex]\frac{x}{4}=\frac{180}{18}[/tex]

[tex]\frac{x}{4}=10[/tex]

[tex]\implies x = 4\times 10 = 40[/tex]

Hence, the prescribed dosage of a certain medicine for a child 4 years old would be 40 mg.

Anita is filling a small pool for her kids. Currently, there are 60 gallons of water in the pool and she is filling the pool at a rate of 50 gallons every 5 minutes. The pool holds 200 gallons of water.

Which equation represents the amount of minutes ( m) that it will take to fill the pool?

Answers

The equation which represents the amount of minutes.m that it will take to fill the pool is 200 = 60 + 10m

Which equation represents the amount of minutes ( m) that it will take to fill the pool?

Let

m = amount of minutes that it will take to fill the pool

Gallons of water in the pool = 60 gallons

Capacity of the pool = 200 gallons

Additional gallons added per minutes = 50 gallons / 5

= 10 gallons per minutes

The equation:

200 = 60 + 10m

200 - 60 = 10m

140 = 10m

Divide both sides by 10

m = 140/10

m = 14 minutes

Therefore, it takes Anita 14 minutes to fill the pool.

Luke sells you cars for $12 each. His expenses are $3.50 per car, plus $34 for tools. How many cars must he sell for his revenue to equal his expenses?

Answers

Answer:

Step-by-step explanation:

x = number of cars

12x = 3.50x + 34

12x - 3.50x = 34

8.5x = 34

x = 34/8.5

x = 4 <=====he would have to sell 4 cars

In this case, Luke must sell [tex]\(\boxed{4}\)[/tex] cars for his revenue to equal his expenses.

To determine how many cars Luke must sell for his revenue to equal his expenses, let's define the variables and set up the equation.

Let x be the number of cars Luke sells.

Revenue:

Luke sells each car for $12, so his revenue for selling x cars is:

[tex]\[ \text{Revenue} = 12x \][/tex]

Expenses:

Luke's expenses include $3.50 per car and a fixed cost of $34 for tools. So his total expenses for x cars are:

[tex]\[ \text{Expenses} = 3.50x + 34 \][/tex]

We need to find the number of cars x such that his revenue equals his expenses:

12x = 3.50x + 34

To solve for x  subtract 3.50x  from both sides:

12x - 3.50x = 34

8.50x = 34

Now, divide both sides by 8.50:

[tex]\[ \text{Expenses} = 3.50x + 34 \][/tex]

x = 4

Therefore, Luke must sell [tex]\(\boxed{4}\)[/tex] cars for his revenue to equal his expenses.

y = 2019 / (2 + 2019 / (2 + 2019 / (2 + 2019 / ...

We can rewrite using substitution:

y = 2019 / (2 + y)

Solving for y:

y (2 + y) = 2019

2y + y² = 2019

y² + 2y + 1 = 2020

(y + 1)² = 2020

y + 1 = ±√2020

y = -1 ± √2020

Since the repeated fraction must be positive, y = -1 + √2020.

x = (1 + y)²

x = (1 + -1 + √2020)²

x = 2020
