What is the slope of this line? Can someone help because I keep getting 5/2 and it doesn’t look right...
Answer:
2.5
Step-by-step explanation:
You can do rise over run and you get 25/10 which is 2.5 or 5/2. So you are correct
Answer:
2.5
Step-by-step explanation:
Slope = change in y/ change in x
In this case the change in y between two spots is 25 and the change in x is 10. So the slope would be 25/10 which can be simplified to 2.5

Michael giokas car from 150 minutes at a constant speed of 70 miles per hour and then for another 2 hours at a constant speed of 81 miles per hour how far did Michael drive so explain how you got your answer
Step-by-step explanation:
150 minutes = 2.5 hours.
2.5 hours * (70 miles/hr) = 175 miles.
2 hours * (81 miles/hr) = 162 miles
Total distance = 175 + 162 = 337 miles.
Hence Michael drove 337 miles in total.

Answer:
DE = 15 cm, AB = 6 cm
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal.
(a)
[tex]\frac{DE}{BC}[/tex] = [tex]\frac{CE}{AC}[/tex] , substitute values
[tex]\frac{DE}{5}[/tex] = [tex]\frac{24}{8}[/tex] = 3 ( multiply both sides by 5 to clear the fraction )
DE = 15 cm
(b)
[tex]\frac{AB}{CD}[/tex] = [tex]\frac{AC}{CE}[/tex] , substitute values
[tex]\frac{AB}{18}[/tex] = [tex]\frac{8}{24}[/tex] ( cross- multiply )
24AB = 144 ( divide both sides by 24 )
AB = 6 cm

#11: last option is answer
#12: first option is answer
Step-by-step explanation:
#11) 5x + 6 ≤ 11
5x ≤ 5
x ≤ 1 to graph this you need a solid dot on 1 and shading to the left
#12) 5p+ 4 > 14
5p > 10
p > 2 to graph this you need an open dot on 2 and shading to the right
Answer:
11. 5x + 6 <= 11.
12. 5p + 4 > 14.
Step-by-step explanation:
11. THE GRAPH shows that x <= 1.
So it is 5x + 6 <= 11 because
5x <= 5
x <= 1.
12. THE GRAPH shows that p > 2.
So it is 5p + 4 > 14.
5p + 4 > 14
5p > 10
p > 2.
On a 20 sided dice what is the probability that a 11 was rolled?
Answer (round) to the hundredth place value.
Given:
A 20 sided dice is rolled.
To find:
The probability of getting 11.
Solution:
A 20 sided dice is rolled.
On a 20 sided dice, the possible outputs are 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20.
Total number of outcomes = 20
Favorable outcomes or number of 11 = 1
Now,
[tex]\text{Probability of getting 11}=\dfrac{\text{Favorable outcomes}}{\text{Total number of outcomes}}[/tex]
[tex]\text{Probability of getting 11}=\dfrac{1}{20}[/tex]
[tex]\text{Probability of getting 11}=0.05[/tex]
Therefore, the probability of getting 11 is 0.05.

On a map, an art gallery is located at (13,-3). A car wash is located at(13,-5) . If each unit on the map is a city block, how many city blocks is the art gallery from the museum?
Answer:
The art gallery is 2 city blocks from the car wash
Step-by-step explanation:
If the x-coordinates of two points on a line equal, then the line is a vertical lineThe length of a vertical segment whose endpoints are (x, y1) and (x, y2) is Iy2 - y1ILet us solve the question
∵ The art gallery is located at the point (13, -3)
∴ x1 = 13 and y1 = -3
∵ A car wash is located at (13, -5)
∴ x2 = 13 and y2 = -5
∵ x1 = x2 = 13
→ That means the gallery and the car wash located vertically over each other
∴ The distance between them = Iy2 - y1I
∵ y1 = -3 and y2 = -5
∴ The distance between them = I-5 - (-3)I
∴ The distance between them = I-5 + 3I
∴ The distance between them = I-2I
→ Remember the absolute value cancel the negative sign
∴ The distance between them = 2 units
∵ Each unit on the map is a city block
∵ The distance between them is 2 units
→ That means the vertical distance between them is 2 city blocks
∴ The art gallery is 2 city blocks from the car wash

7+x/3=2x-5
Plz help me
The value of x in the given system of equation 7+x/3=2x-5 is 7.2.
What are System of equation?
simultaneous equations, system of equations Two or more equations in algebra must be solved jointly (i.e., the solution must satisfy all the equations in the system). The number of equations must match the number of unknowns for a system to have a singular solution.
There are four methods to solving systems of equations: graphing, substitution, elimination and matrices.
Given a System of equation 7+x/3=2x-5
Simplifying this equation
7+x/3=2x-5
=> 2x - x/3 = 12
=> 5x/3 = 12
=> x = 36/5
=> x = 7.2
Therefore, The value of the x for the given Equation is 7.2.

2. Atmospheric carbon dioxide (CO 2 ) is believed to be a primary factor in global warming Levels of CO, are increasing because human activities, such as burning fossil fuels, send more CO 2 , into the atmosphere than natural biological processes remove Estimates in 2012 suggested that Earth's atmosphere contained 393 parts per million (ppm) of co 2 with another 2 ppm added each year a) Based on findings of the 2012 study, what function could be used to estimate the atmospheric CO 2 at any time x years after 2012 b) Using your model from part a What level of atmospheric CO 2 can be expected in the year 2025? In what year can we expect atmospheric CO 2 to reach 400 ppm? M o nd c Suppose that omissions from
Answer:
(a)Required relation is 393 + 2x ppm
(b)Amount of [tex]CO_2[/tex] concentration in 2025 is 419 ppm
(c)After 3.5 years concentration of [tex]CO_2[/tex] is 400 ppm
Step-by-step explanation:
From the question it is given that :
Estimated [tex]CO_2[/tex] in atmosphere in 2012 is 393 (parts per million)ppm
[tex]CO_2[/tex] level increasing per year is 2 ppm
(a) Let y be the concentration of [tex]CO_2[/tex] in atmosphere after x years from 2012 then:
y = 393 + 2x ppm
Therefore required relation is 393 + 2x ppm
(b) amount of [tex]CO_2[/tex] in 2025 i.e.,x = 13 years after 2012 is y
y = 393 + 2 x 13 = 393+ 26 = 419 ppm
Therefore, amount of [tex]CO_2[/tex] concentration in 2025 is 419 ppm
(c) give y = 400 ppm and x be the year then
400 = 393 + 2x
2x = 7
⇒ x = 3.5 years
Therefore after 3.5 years concentration of [tex]CO_2[/tex] is 400 ppm

What percentage of people receiving treatment 2 had improved health?
Answer:
58
Step-by-step explanation:
thank me later
The percentage of people receiving treatment 1 had improved health is 48%. The percentage of people receiving treatment 2 had improved health will be 52%.
What is the percentage?The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.
Given that scientists give two different treatments to people who have the flu and determine if their health improved. The results of the test are in the two-way table.
The percentage of people receiving treatment 1 had improved health is calculated as,
Percentage = 23 / ( 23 + 25 )
Percentage = 0.48 x 100 = 48%
The percentage of people receiving treatment 2 had improved health is calculated as,
Percentage = 25 / ( 23 + 25 )
Percentage = 0.52 x 100 = 52%
Therefore, the percentage of people receiving treatment 1 had improved health is 48%. The percentage of people receiving treatment 2 had improved health will be 52%.

if PQ is reflected across the X-axis, what will be the coordinates of P'Q' repeated?
i think it is a but i am sorry if it wrong
Step-by-step explanation:
Answer:
Graph
Step-by-step explanation:
If point P has coordinates (x1, y1) and point Q has coordinates (x2, y2), and PQ is reflected across the X-axis, the coordinates of the reflected points P' and Q' can be obtained by flipping the y-coordinates of P and Q and keeping the x-coordinates the same.
Therefore, the coordinates of P' will be (x1, -y1) and the coordinates of Q' will be (x2, -y2).
So, if you want to find the coordinates of the reflected line segment P'Q', you just need to take the coordinates of P' and Q' and connect them with a line. The resulting line segment will have endpoints (x1, -y1) and (x2, -y2).
Note that the length of the reflected line segment P'Q' will be the same as the length of the original line segment PQ, but the orientation of the reflected line segment will be reversed with respect to the X-axis.
