I lost in this problem and I can’t find my way out

elixir [45]

Two angle that form a linear pair are supplementary meaning they add to equal 180° (straight line).

make the bigger angle = x
then smaller angle = x - 30°

x + x - 30 = 180
2x - 30 = 180
2x = 180 + 30
2x = 210
x = 210/2
x = 105

The question is to find the smaller angle which was: x - 30

105 - 30 = 75°

A concert manager counted 600 ticket receipts the day after a concert. The price for a student ticket was $13.50, and the price

The number of student tickets is 175 and the number of adult tickets is 425.

<h3>What is an expression?</h3>

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

<h3 />

Given that:-

A concert manager counted 600 ticket receipts the day after a concert. The price for a student ticket was $13.50, and the price for an adult ticket was $17.00. The register confirms that $9,587.50 was taken in

Suppose the number of the student ticket is St and adult are At.

St + At = 600

St = 600 - At

Another expression for the total amount will be given as:-

13.5St + 17At = 9587.50

Put the value of St in the equation to find the value of At.

13.5( 600 - At) + 17At = 9587.50

8100 - 13.5At +17At = 9587.5

17At - 13.5 At = 9587. 5 - 8100

3.5 At = 1487.5

At = 425

St + At = 600

St = 600 - At = 600 - 425 = 175

Therefore the number of student tickets is 175 and the number of adult tickets is 425.

Find the zeros of y=x^2-8x-3

Anton [14]

This is gonna be the answer. It’s 4+sqrt(19) and 4-sqrt(19). Which is approximately 8.36 and -0.36. In x intercept form, it’s (8.36,0) and (-0.36,0) also I solved this by completing the square. I hope this helps!!! Mark as brainliest!!!

Rohan invested in a precious mineral. The value of the mineral tends to increase by about 9% per year. He invests $12,000 in 201

Ratling [72]

Answer:

price in 2025=21934 dollar

Step-by-step explanation:

increase in price=9% per year

price in 2018=12000 dollar

increase in amount between 2018 to 2019= $\frac{09}{100}$ ×12000

increase in amount between 2018 to 2019=1080

price in 2019=12000+1080=13080

increase in amount between 2019 to 2020= $\frac{09}{100}$ ×13080

increase in amount between 2019 to 2020=1177

price in 2020=13080+1147=14257

increase in amount between 2020 to 2021= $\frac{09}{100}$ ×14257

increase in amount between 2020 to 2021=1283

price in 2021=12000+1080=15540

increase in amount between 2021 to 2022= $\frac{09}{100}$ ×15540

increase in amount between 2021 to 2022=1399

price in 2022=15540+1399=16938

increase in amount between 2022 to 2023= $\frac{09}{100}$ ×16938

increase in amount between 2022 to 2023=1524

price in 2023=16938+1524=18462

increase in amount between 2023 to 2024= $\frac{09}{100}$ ×18462

increase in amount between 2023 to 2024=1661

price in 2024=18462+1661=16938=20123

increase in amount between 2024 to 2025= $\frac{09}{100}$ ×20123

increase in amount between 2024 to 2025=1811

price in 2025=20123+1811=21934 dollar
