Answer:

Clearly show i can't see ur answer

Answer:

x = 60

Step-by-step explanation:

These angles are alternate exterior angles because they are on the opposite side of the transversal line and on the outside of a set of two non-transversal lines.

The alternate exterior angles theorem explains that if a pair of non-transversal lines are parallel, then the alternate exterior angles are congruent.

We can use the following equation to solve:

46 = 3x-14

Simplify.

60 = 3x

x= 60

A new auditorium is begging built for a college the balcony has 200 seats the floor has 25 rows with x seats in each row the number of people in the auditorium must be under 750 to meet safety regulations what is the solution of this inequality and what is it's meaning

Answers

Question:

A new auditorium is being built for a college. The balcony has 200 seats. The floor has 25 rows with x seats in each row. The number of people in the auditorium must be under 750 to meet safety regulations. What is the solution of this inequality, and what is its meaning?​

Answer:

[tex]200 + 25x < 750[/tex]

Number of seats in a row must be less than 22

Step-by-step explanation:

Given

Total = Less than 750

Current Seats = 200

Rows = 25

Seat per row = x

Required

Represent as an inequality

The scenario will be represented as:

[tex]Current\ Seats + Rows * x = Total[/tex]

Substitute 200 for Current Seats

[tex]200 + Rows * x = Total[/tex]

Substitute 25 for Rows

[tex]200 + 25* x = Total[/tex]

[tex]200 + 25x = Total[/tex]

Substitute <750 for Total.

The equation then becomes

[tex]200 + 25x < 750[/tex]

Solving further:

[tex]25x < 750 - 200[/tex]

[tex]25x < 550[/tex]

[tex]x < \frac{550}{25}[/tex]

[tex]x < 22[/tex]

This means that:

Number of seats in a row must be less than 22

Ashton is looking for new soccer cleats for the new season. He found the perfect pair, Nike vapor edge pro 360, But the cost is $140 without taxes. Ashton only his $150. If he has to pay the full price and an 8% tax fee, would he be able to buy his cleats? Why or why not.​

Answers

To find the amount of tax you need to multiply the cost by the percentage of tax
140•0.08=11.2
To then find the total cost of the shoes with tax you add 140 + 11.2 = 151.2
So no ashton will not be able to afford the shoes because he is 1.2 dollars over budget.

Find the inverse of the function.

Answers

Answer:

The option 'b' is true.

Step-by-step explanation:

Given the expression

[tex]f\left(x\right)=\frac{2}{x+7}[/tex]

A function g is the inverse of the function f if for y=f(x), x=g(y)

[tex]y=\frac{2}{x+7}[/tex]

Replace x with y

[tex]\:x=\frac{2}{y+7}[/tex]

solve for y

[tex]y=\:\:\frac{2}{x}-7[/tex]

Thus,

[tex]f^{-} (x)=\frac{-7x+2}{x}[/tex]

Therefore, option b is true.

Round 11,900 to the nearest thousand.

5 stars for a correct answer.

Answers

Answer:

12,000

Step-by-step explanation:

The two thousands that 11,900 is in between are 11,000 and 12,000 which are our two options to choose from. 11,900 is only 100 away from 12,000 and 900 away from 11,000. Because the distance between 11,900 and 12,000 is shorter than the distance between 11,900 and 11,000, this means that 12,000 would be our answer since it is closer.

(I'm really sorry if this is confusing, I'm not good with words)

In 2005, 120 students at Lincoln High School

same school had smart phones. Which of the
following best describes the annual rate of change
in the number of smart phones students had from
2005 to 2010 at Lincoln High School?
A) The average increase in the number of smart
phones per year is 40.
B) The average increase in the number of smart
phones per year is 45.
C) The average increase in the number of smart
phones per year is 50.
D) The average increase in the number of smart
phones per year is 55.

Answers

Answer:

The average increase in the number of smart

phones per year is 45

Step-by-step explanation:

Given that :

Number of students who had phones in 2005 = 120

Number of students who had phones in 2010 = 345

(345 - 120) / 5

225 / 5

= 45

Hence, average increase in number of smartphones per year = 45
