Two exterior angles of a triangle equal 100° and 150°. Find all the interior angles

Answers

180°-100°= 80° (angle 1)
180°-150°= 30° (angle 2)

180°-80°-30°= angle 3
angle 3 = 70°

∴ the interior angles are 80°, 30° and 70°

The angles of the triangle will be 70°, 30°, and 80°.

What is the triangle?

A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.

We know that the sum of the interior and the exterior angles is 180 degrees.

Two exterior angles of a triangle equal 100° and 150°.

The interior angle corresponding to the exterior angle of 100° will be

⇒ 180° - 100°

⇒ 80°

The interior angle corresponding to the exterior angle of 100° will be 80°.

The interior angle corresponding to the exterior angle of 150° will be

⇒ 180° - 150°

⇒ 30°

The interior angle corresponding to the exterior angle of 150° will be 30°.

Then the third angle of the triangle will be

⇒ 180° - 80° - 30°

⇒ 70°

The angles of the triangle will be 70°, 30°, and 80°.

A barge that is used to transport bulk items is the shape of a rectangular prism and is 90 feet long, 35 feet wide, and 12 feet deep. If the barge can only be filled to a height of 75% of its depth, what volume of bulk items can the barge hold? ft3

Answers

Barge volume = 90 * 35 * 12 = 37 800 ft³

75% = 75/100 = 0.75

37 800 * 0.75 = 28 350 ft³ (barge can hold).

Final answer:

The barge can hold 28,350 cubic feet of bulk items when filled to 75% of its depth, calculated by using the volume formula for a rectangular prism.

Explanation:

To calculate the volume of bulk items the barge can hold, we first determine the maximum height to which it can be filled. This is 75% of the barge's depth. Therefore, the fill height is 75% of 12 feet, which equals:

0.75 × 12 ft = 9 ft.

The volume V that the barge can hold is given by the formula for the volume of a rectangular prism:

V = length × width × height

Substituting the given dimensions and the fill height into the formula, we get:

V = 90 ft × 35 ft × 9 ft = 28,350 ft³.

So, the barge can hold 28,350 cubic feet of bulk items when filled to 75% of its depth.

Algebraic expression for 5 times a number

Answers

it could be 5x, 5 being the digit, x being "a number"

Final answer:

The algebraic expression for 5 times a number is 5x.

Explanation:

The algebraic expression for 5 times a number is 5x.

The variable x represents the unknown number.

When you multiply 5 by any number, you can represent it as 5 times that number.

So, if the number is 10, the expression would be 5 times 10, which is equal to 50.

A building has an entry the shape of a parabolic arch 96 ft high and 18 ft wide at the base, as shown below. Find an equation for the parabola if the vertex is put at the origin of the coordinate system

Answers

To determine the equation of the parabola of the arch, we need to know the general equation for a parabola and its elements. The arch is facing down so the general equation written in its vertex form would be as follows:

y - k = - a(x - h)^2

where (h,k) represents the vertex of the parabola and a represents the focus and tells you where the graph opens. If a is positive then it opens upward and if its is negative, it opens downward.

For this given situation, the vertex is at point (0,0) or at the origin so that h and k are zero.

y= - a(x)^2

To determine the value of a, we use the measurements given above. We make use of the maximum height and the span of the parabola. The point we will be using would be (18/2 , 96 ).

y= - a(x)^2
96= - a(9)^2
a = -32/27

So, the equation of the parabola would be
y= - (32/27)(x)^2

The equation of the parabola if the vertex is put at the origin of the coordinate system is y =-32/27x^2

The height of the arch is given s:

height = 96 ft

The width of the base is given as:

width = 18 ft

A point on the building would be

(x,y) = (width/2, height)

So, we have:

(x,y) = (18/2, 96)

Simplify

(x,y) = (9, 96)

A parabola is represented as:

y = -a(x - h)^2 + k

The vertex of the parabola is at the origin.

So, we have:

y = -ax^2

Substitute (x,y) = (9, 96)

96 = -a * 9^2

This gives

96 = -81a

Divide both sides by 81

a= -96/81

So, the equation of the parabola is

y =-96/81x^2

Simplify

y =-32/27x^2

Answers

The extended version of the link given shows a triangle with sides of measurements equal to 13, 16, and 15 units.

Since we are given with the measurements of all sides, we use the Heron's formula.

A = sqrt ((s)(s - a)(s - b)(s - c))

where s is the semiperimeter and a, b, and c are the measures of the sides.

s = (a + b + c) /2
s = (13 + 15 + 16) / 2 = 22

Substituting this to the equation for the area,
A = sqrt ((22)(22 - 13)(22 - 15)(22 - 16))
A = 91.19 square units

Thus, the area is approximately equal to 91.2 square units. The answer is letter B.

A cyclist rides her bike at a speed of 10 miles per hour. What is this speed in kilometers per hour? How many kilometers will the cyclist travel in 2 hours? In your computations, assume that 1 mile is equal to 1.6 kilometers. Do not round your answers.

Answers

Final answer:

The speed of the cyclist is 16 km/h and she will travel a distance of 32 kilometers in 2 hours.

Explanation:

To convert the speed from miles per hour (mph) to kilometers per hour (km/h), we can use the conversion factor of 1 mile = 1.6 kilometers. So, if a cyclist rides her bike at a speed of 10 mph, we can multiply 10 by 1.6 to find the speed in km/h. Therefore, the speed of the cyclist is 16 km/h.

To calculate the distance traveled in 2 hours, we can use the formula: distance = speed × time. Since the speed of the cyclist is 16 km/h and the time traveled is 2 hours, we can multiply 16 by 2 to find the total distance. Therefore, the cyclist will travel 32 kilometers in 2 hours

Final answer:

To convert the speed from miles per hour (mph) to kilometers per hour (km/h), multiply the speed by the conversion factor. The cyclist will travel 32 kilometers in 2 hours.

Explanation:

To convert the speed from miles per hour (mph) to kilometers per hour (km/h), we can use the conversion factor of 1 mile = 1.6 kilometers. Thus, if the cyclist rides at a speed of 10 mph, we can find the speed in km/h by multiplying it by the conversion factor:

Speed (km/h) = Speed (mph) x Conversion factor

Speed (km/h) = 10 mph x 1.6 km/mi = 16 km/h

Next, to calculate the distance the cyclist will travel in 2 hours, we can use the formula:

Distance = Speed x Time

Distance = 16 km/h x 2 hours = 32 kilometers

A sequence has its first term equal to 8, and each term of the sequence is obtained by adding 6 to the previous term. If f(n) represents the nth term of the sequence, which of the following recursive functions best defines this sequence?

Answers

A recursive formula for an arithmetic sequence is:

a(n)=a(n-1)+d, where n=term number and d=common difference.

Since we are told that d=6:

a(n)=a(n-1)+6, a1=8

They may want:

f(n)=f(n-1)+6, a1=8

I never understood why they teach this instead of explicit formulas because the above is pretty useless if you simply want say the 1031st term, you would need to do a lot of calculations to find it. :P. The explicit function is:

a(n)=a+d(n-1), here a=8 and d=6 so

a(n)=8+6(n-1)

a(1031)=8+6(1031-1)=6188

A) ≈ $276,582
B) ≈ $286,263
C) ≈ $306,652
D) ≈ $296,282

Answers

In order to determine the value of the rent after x years, we need to generate a function which would relate the value of the rent and the time in years. The rate by which the rent increases is said to be 3.5% per year. So, if we do it manually, we would have:

value of the rent = 225000 + 225000 (.035) + 225000 (.035)(.035) + ........

However, this is a tedious and long process since we need to continue until year 8. We need to simplify it to an expression. We do as follows:

value of the rent = 225000 + 225000 (.035) + 225000 (.035)(.035) + ........

We factor out the initial rent,

value of the rent = 225000 (1 + (.035) + (.035)(.035) + ........)

Then, we simplify the terms inside the first parentheses,

value of the rent = 225000 (1 + (.035))^x

where x is the number of years. We then substitute 8 to x to determine the value of the rent.

value of the rent = 225000 (1 + (.035))^8 = 296282.03

Answers

Therefore, the two friends will be 150 miles apart in 2 hours.

Answer:

The two friends will be 150 miles apart in 2 hours

Step-by-step explanation:

The two friends left the school at the same time and drove in opposite directions. One of them have a speed of 40 miles per hour while the other have a speed of 35 miles per hour .

The both of them are moving apart at the rate = 40 + 35 = 75 miles per hour
