Answer:
32.3° and
147.7°
Step-by-step explanation:
Supplementary angles are angles with the sum of 180°
if one of the angle is 115.4° less than other then
(180 - 115.4) ÷ 2 = 32.3° is the measure of smaller angle and
32.3 + 115.4 = 147.7° is the measure of larger angle
Mike is 5 years older than David. Four times David’s age increased by three years equals three times Mike’s age decreased by two years. Find Mike’s age.
Answer:
15 years
Step-by-step explanation:
Write as an algebraic equation-
D+5=M
4D+3=3M-2
substitute
4D+3=3D+15-2
4D+3=3D+13
subtract 3 and 3D
D=10
Plug in D
10+5=M
M=15
Jay has lost his mother’s favorite necklace, so he will rent a metal detector to try to find it. A rental company charges a one time rental fee of $15 plus $2 per hour to rent a metal detector. Jay has only $35 to spend. What is the maximum amount of time he can rent the metal detector?
Answer:
he can rent it for 10 hours
Step-by-step explanation:
35 - 15 = 20
20 divided by 2 equals 10
Answer:
10 hours
Step-by-step explanation:
Say x is the number of hours he can rent the detector at most. Using it, we can set up this equation:
15 + 2x = 35
Subtract 15 from both sides
2x = 20
Divide by 2 on both sides
x = 10

Solve 3n−2=4n−6 . Please help.
Step-by-step explanation:
Step 1: Subtract 4n from both sides.
3n−2−4n=4n−6−4n
−n−2=−6
Step 2: Add 2 to both sides.
−n−2+2=−6+2
−n=−4
Step 3: Divide both sides by -1.
−n−1=−4−1

Answer:
Round 11,900 to the nearest thousand.
5 stars for a correct answer.
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.

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
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

The angles of AABC have the extended ratio of 7:8:15, respectively. Calculate the value for each of the angles A, B,
and C. Remember the angles in a triangle sum to 180 degrees!
Answer:
Step-by-step explanation:
Remark
A B C have to be multiplied by the same something. No matter what they are multiplied by the sum will be 180 degrees.
Equation
Let the angle ratios be multiplied by x
7x + 8x + 15x = 180
30x = 180
x = 180/30
x = 6
Answer
7*6 = 42
8*6 = 48
15*6 = 90
Total 180 as it should
-4(2x+4)=-7x
solve for x
Answer:
x should equal 16

In 2005, 120 students at Lincoln High School
had smart phones. By 2010, 345 students in the
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.
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
Find the inverse of the function.
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.

9 is subtracted by the sqaure of a number
Answer:
I believe it is x^2-9
Step-by-step explanation:
Since we don't have a specific "number" you use x. It says it's squared to put an exponent of 2. It also says that 9 is subtracted by it so put -9.
Find the area of the circle.
Answer:
A=346,6 in²
Alternative C
Step-by-step explanation:
Length of circunference:
L=2πR, where r is the radius
Area of circle:
A=πR²
We know that L=66
66=2πR, then:
πR=33in
[tex]R=\frac{33}{\pi }[/tex]
Thus:
[tex]A=\pi (\frac{33}{\pi} )^{2}[/tex]
[tex]A=\frac{1089}{\pi} \\\\A=346,63[/tex]

Estimate the solution of the equation a(x) = b(x)
IMAGE BELOW
Answer:
The solution of the equation a(x) = b(x) is (9, 5.5)
Step-by-step explanation:
The solution of the system of the linear equations is the common ordered pair in their solutions, this solution is the point of intersection of the lines which represent the two equations graphically
In the given figure
∵ There are two lines, the blue line, and the red line
→ Let the blue line represents a(x) and the red line represents b(x)
∵ The solution of the equation a(x) = b(x) is the point of intersection of
the two lines
∵ The x-coordinate of this point is 9
∵ The y-coordinate of this point is between 5 and 6 (5.5)
∴ The coordinates of the point of intersection are (9, 5.5)
∴ The solution of the equation a(x) = b(x) is (9, 5.5)

30) 80°
Step-by-step explanation:
29)
8x + 4 = 11 + 7x
x = 7
∴ ∠ = 11 + 7(7) = 60

14x - 4 = 12x + 8
2x = 12
x = 6
∴ ∠ = 14(6) - 4 = 80
It cost $2.50 to rent bowling.each game costs $3.25.you have $22. How many games can you bowl
Answer:
6 games
Step-by-step explanation:
Use the equation 2.5+3.25x=22 to solve in which $2.50 is the initial amount to rent for Bowling, $3.25 the amount of game that is played, $22 for what you have, and x in which is the amount of games you can play at the max. Subtract 2.5 on both sides to get to 3.25x = 19.5. Divide 3.25 on both sides to get your final answer as 6 for your x value in which you can play up to 6 games.
Answer:
6 games
Step-by-step explanation:
you do 2.50 - 22 this you divide 3.25 by what you have left
