a car travels 1.2 miles from point a to point b. the car then turns at point b and travels 1.8 miles to point c before heading back to point a. the distance from point point c to point a is 1.6 miles. if the cars path is represented by a triangle what angle turn
Since we are given with the three sides of the triangle and asked to determine the angle, we can use the cosine law.
b² = a² + c² - 2ac(cosB)
Substituting the known values,
(1.8)² = (2.4)² + (1.6)² - 2(2.4)(1.6)(cosB)
The value of B from the equation is 48.6°.
Answer:
B = 60.6 degree
Step-by-step explanation:
Side AB, c = 1.2 miles
Side BC, a = 1.8 miles
Side CA, b = 1.6 miles
Use Cosine rule to find the angle B.
[tex]Cos B = \frac{a^{2}+c^{2}-b^{2}}{2ac}[/tex]
Putting the values of a, b and c
[tex]Cos B = \frac{1.8^{2}+1.2^{2}-1.6^{2}}{2\times 1.8\times 1.2}[/tex]
[tex]Cos B = \frac{3.24+1.44-2.56}{4.32}[/tex]
[tex]Cos B = 0.491[/tex]
B = 60.6 degree

Answer:
y = 6
Step-by-step explanation:
⇒ 17 y + 2 = 5 y + 74
→ ( - 5 y from both sides )
⇒ 12 y + 2 = 74
→ ( -2 from both sides )
⇒ 12 y = 72
( ÷ by 12 on both sides )
⇒ y = 6
Answer:
y = 6
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
17*y+2-(5*y+74)=0
Pull out like factors :
12y - 72 = 12 • (y - 6)
Solve : 12 = 0
Add 6 to both sides of the equation :
y = 6

The Lin family bought a dozen bagels. They ate 1/4 of the bagels today and 5/12 of the bagels yesterday. What fraction of the bagels did they eat in all? Explain how you found your answer.
Answer:
2/3
Step-by-step explanation:
To be able to find what the total fraction of bagels eaten, the fractions need to have common denominators. To do this, you multiply 1/4 by 3 in both the numerator and the denominator. Now that the two fractions have the same denominator, you can add the fraction's numerator to get the total fraction, 8/12. However, 8/12 can be simplified more, so you divide by 4 and end up with 2/3.

Can 5, 6 and 30 squared form a right triangle?
Answer:
no
Step-by-step explanation:
A triangle is equal to 180.
5²+6²=30²
25+36=900
61=900
No solution
Answer:
No; it cannot form a right triangle
Step-by-step explanation:
Use the Pythagorean theorem.
5 squared + 6 squared ≠ 30 squared
25 + 36 ≠ 90000
61 ≠ 90000
Also, note that that the sum of the two shorter lengths have to be greater than the longer length to form any kind of triangle.
What is the solution to the set of equations in the form (a,b)
a-3b=16
a=b-2
Answer:
(-11, - 9)
Step-by-step explanation:
Given the 2 equations
a - 3b = 16 → (1)
a = b - 2 → (2)
Substitute a = b - 2 into (1)
b - 2 - 3b = 16
- 2b - 2 = 16 ( add 2 to both sides )
- 2b = 18 ( divide both sides by - 2 )
b = - 9
Substitute b = - 9 into (2) for the corresponding value of a
a = - 9 - 2 = - 11
Solution is (- 11, - 9)

find the range
3, -9, 7, -1, 5, -4, 2
Answer:
16
Step-by-step explanation:
to find the range, you have to subtract the smallest number from the biggest number.
In this case 7-(-9)
7-(-9)=16
range=16
Answer:
16
Step-by-step explanation:
The range is the difference between the greatest number and the least number.
The greatest number here is 7.
The least number here is -9
Now, Subtract the least number from the greatest number:
7 - (-9) = 16
Hence the range is 16.
The price of a flight was increased by 3% to £720. What was the price before the increase?
Give your answer to the nearest penny.
Step-by-step explanation:
let the price be x before increased.
After it is increased then it becomes 1.03x
i.e. 1.03x= 720
x=699.03 which is the price after it is increased.
The question is an illustration of percentage increase, and the price before the increase is £699
How to determine the initial price?The given parameters are:
Initial = x
Rate = 3%
New price = £720
The equation of the initial price is:
x * (1 + rate) = New price
So, we have:
x * (1 + 3%) = 720
Evaluate the sum
x * 1.03 = 720
Divide both sides by 1.03
x = 699
Hence, the price before the increase is £699

What is the value of x?
Answer:
x = 12
Step-by-step explanation:
The 2 given angles form a straight angle and are supplementary, thus
10x - 20 + 6x + 8 = 180
16x - 12 = 180 ( add 12 to both sides )
16x = 192 ( divide both sides by 16 )
x = 12

Imagine that you are an elementary-school math teacher. You need to develop a lesson plan for teaching measurement and will be using items such as rulers and three-dimensional geometric shapes. Describe the strategies you will use to adjust instruction to include a student who has a visual disability
I don’t see what you trying to explain
When teaching measurement to a student with a visual disability, use tactile materials, auditory cues, non-visual measurement tools, real-world examples, and encourage peer collaboration.
Explanation:When teaching measurement to a student with a visual disability, it is important to use alternative methods of instruction that focus on touch and auditory experiences. Here are some strategies you can use:
Provide tactile materials: Allow the student to explore three-dimensional geometric shapes with their hands. You can use manipulatives or 3D models to enhance their understanding.Use auditory cues: Describe the measurements using clear and precise language. For example, instead of saying 'This object is 5 centimeters long', say 'This object is as long as five paperclips.' This helps the student form a mental image.Include non-visual measurement tools: Utilize tools like braille rulers, talking calculators, or measuring tapes with tactile markings. This allows the student to independently measure objects.Provide real-world examples: Relate measurements to everyday situations. For example, you can discuss the length of a classroom desk or the volume of a water bottle. This helps the student connect measurement concepts to their own experiences.Encourage peer collaboration: Pair the student with a sighted buddy who can assist them during hands-on activities. This promotes inclusive learning and allows the student to engage with their peers.Learn more about How to adjust instruction for a student with a visual disability in math measurement lessons here:https://brainly.com/question/39515127

Find the value of x in the isosceles triangle shown
Answer:
x = 8√5
Step-by-step explanation:
The large triangle is divided into two smaller ones. The right one has one leg of length 8, one leg of length x/2, and hypotenuse of length √80.
Appling the Pythagorean Theorem, we can find x:
8² + (x/2)² = (√80)²,
or: x^2
64 + x^2/4 = 80, or ------- = 80
4
Then x^2 = 320 = 64*5. Taking the square root of both sides, we get:
x = 8√5

A city has a population of 390,000 people. Suppose that each year the population grows by 8.75%. What will the population be after 12 years?
After 12 years, the population will be approximately 993,993 people.
The city's current population is 390,000 and it grows at a rate of 8.75% each year. To find the population after 12 years, we use the formula for exponential growth:
P(t) = P° × (1 + r)t
Where:
P(t) is the future populationP° is the initial populationr is the annual growth rate (expressed as a decimal)t is the number of yearsFirst, convert the growth rate to decimal form:
8.75% = 0.0875
Next, apply the exponential growth formula:
P(12) = 390,000 × [tex](1 + 0.0875)^{12}[/tex]
P(12) = 390,000 × [tex]( 0.08750)^{2}[/tex]
Using a calculator, we get:
P(12) = 390,000 × 2.5487
P(12) = 993,993
