Answer:
C
Step-by-step explanation:
First we need to find out y.
5y + 45 = 180 (angles on straight line)
y = 27
5y = 135
Then we could apply the angle sum of a pentagon to find out z.
90 + 5y + z + 82 + 135 = 180(5-2)
442 + z = 540
z = 98 i.e. C

25 POINTS!!! The equation y=470x represents the relationship between x, the time that a plane flies in hours, and y, the distance the plane flies in miles for plane A. The table represents the relationship for plane B. Find the slope of the graph for each plane and the plane's rate of speed. Determine which plane is flying at a faster rate of speed. Look at the photo.
Answer:
Step-by-step explanation:
For plane A,
Equation that represents the relationship between time 'x' and distance 'y' is,
y = 470x
By comparing this equation with the slope-intercept form of the equation,
y = mx + b
m = slope = 470
b = 0
Here, slope represents the speed of plane A.
Therefore, speed of plane A = 470 mi per hour
For plane B,
From the given table,
Slope of the graph = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
= [tex]\frac{960-480}{2-1}[/tex]
= 480
Speed of plane B = 480 miles per hour
Since, speed of plane B is more than plane A,
Plane B is flying faster.
What is the y intercept of the following equation
3x-2y=4
Answer: y = -2 + 3/2x
Step-by-step explanation:
1. 3x - 2y = 4 (move the variable to the right of the equal)
1.1. -2y = 4 - 3x
2. y = -2 +3/2x (divide both sides by -2)
Which expression is equivalent to (0.5x+7)−(1.2x−3)?
(0.5x+1.2x)+(7+3)

Gary spent 1/6 of his money on baseball cards, 3/10 of the remaining on candy and save the rest. If he spent $6 on baseball cards, how much money did he have in the beginning? Pls anwser
Answer: $36
Step-by-step explanation:
Let the total amount of money that he had in the beginning be represented by x.
Since Gary spent 1/6 of his money on baseball cards which was $6. This will then be solved further as:
1/6 × x = 6
1/6x = 6
x = 6 × 6
x = 36
The total amount of money that he had in the beginning was $36

During 24 hours a radio station spends 1/5 of the time playing rock music,2/3 playing hip hop, and the rest playing dance music.How much time is spent playing dance music?
Answer:
[tex]3.2\:\text{hours}[/tex] is spent playing dance music.
Step-by-step explanation:
Given: During [tex]24[/tex] hours a radio station spends [tex]\frac{1}{5}[/tex] of the time playing rock music, [tex]\frac{2}{3}[/tex] playing hip hop, and the rest playing dance music.
To find: How much time is spent playing dance music?
Solution:
We have,
Radio station spends [tex]\frac{1}{5}[/tex] of the time playing rock music.
Radio station spends [tex]\frac{2}{3}[/tex] of the time playing hip hop.
Radio station spends rest of the time playing dance music.
So,
Time spend on playing rock music [tex]=\frac{1}{5}\times24 = 4.8\:\text {hours}[/tex]
Time spend on playing hip hop [tex]=\frac{2}{3}\times24 = 16\:\text {hours}[/tex]
Now, total time radio station spends on all the three music is [tex]24[/tex] hours.
Therefore, rest of the time[tex]=24-(16+4.8)=3.2\:\text{hours}[/tex]
It is given that in the rest of the time, the radio station plays dance music.
Hence, [tex]3.2\:\text{hours}[/tex] is spent playing dance music.

Peter runs laps on the school track every afternoon. He wants to run no more than 60 minutes a day. He can consistently run each lap in 1.5 minutes. Which inequality best represents the situation and represents x, the greatest number of laps Peter could run in a day?
Answer:
1.5x ≤ 60
Step-by-step explanation:
He wants to run no more than 60 minutes a day
No more than means Less than or equal to with the inequality sign of ≤
Each lap = 1.5 minutes.
The greatest number of laps Peter could run = x
Therefore, the inequality that best represents the situation and represents x, the greatest number of laps Peter could run in a day
1.5 × x ≤ 60 minutes
= 1.5x ≤ 60
Solving for x
1.5x ≤ 60
x ≤ 60/1.5
x ≤ 40 laps
Hence, the Greatest number of laps = x that he can run is 40 laps

The solution of the given expression if p = 1, r= -7, and s = -2 will be; -5 and 1/2
What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
WE have been given an expression as
-3p-2r / 6+4s
We have to substitute the value p = 1, r= -7, and s = -2 to find the solution.
Plug the values;
-3p-2r / 6+4s
-3 (1) -2 (-7) / 6+4(-2)
-3 + 14 / 6 - 8
11 / -2
Hence, the solution of the given expression if p = 1, r= -7, and s = -2 will be; -5 and 1/2
