Answer: 6 miles
Step-by-step explanation:
If you picture this scene in your head, you will get a simple 3x4x5 right triangle. 4 times 2 is 8, 5 times 2 is 10, so Sarah should, by now, have traveled 3 times 2 miles.
Final answer: Beth has traveled 6 miles after an hour.
Hope this helped! :)
Helping tip: The reason it is not 4 is because they are not traveling west and east away from each other. They are traveling north and east, so they are moving in two directions to form a right triangle, and the hypotenuse would be 10 (miles). The side, or distance, that Beth has traveled is 8. So as this is a typical variation of a 3x4x5 triangle Beth will have traveled 6 miles.

How do you solve 5[2p−4(p+5)]=25 properly?
Answer:
Step-by-step explanation:
5[2p-4(p+5)]=25
or, 2p-4(p+5)=5
or, 2p-4p-20=5
or, -2p=5+20
or, -2p=25
or, 2p=-25
or, p=25/2
so, p=12.5

Answer:
2/3 is your answer
Step-by-step explanation:
Hope this helps
P.S.(from k12)
The slope of the line is 2/3.
Here,
Graph of a line on coordinate plane. Axes are labeled x and y.
Three points are with ordered pairs (2, 3), (5, 5), and (8, 7) and the line passes through these three points.
We have to find the slope of the line.
What is the slope of the line?
Let two points (x₁, y₁) and (x₂, y₂) are on the line, then slope of the line is calculated as;
[tex]m = \frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
Now,
Three points are passes through the line are (2, 3), (5, 5), and (8, 7).
To find the slope, Let any two point from three given points.
Let (2, 3) and (5, 5) on the line.
Hence, Slope is calculated as,
⇒ [tex]m = \frac{5-3}{5-2} = \frac{2}{3}[/tex]
Therefore, The slope of the line is 2/3.

Answer: B.no
Step-by-step explanation:
To figure this out, plug (1, -4) into the equation y=-2x. 1 is the x value, so we plug it into the x. -4 is the y value, so we plug it into the y spot. In the end we get -4=-2(1). Is this true? No, it isn't. Therefore it is not an answer

At 12 noon if the temperature is 38°C and if it decreases at the rate of 2°C per hour, then what would be the temperature at 5pm?
Answer:
38-2(5) = 28
So the temperature would be 28 degrees celsius
Answer: Teperature at 5PM will be 28°C
Ok so at 12 its 38°C
And it dcreases at 2°C an hour, we need to find the teperature at 5 o clock.
The number of hours between 12 and 5 mutiplied by 2 will give us the trail in temperature and then subtracting the trail i temperature witht the temperature a 12 will give us the teperature at 5 o clock.
SO,
hours between 12 PM and 5 PM is 5 hours
As, the temperature decreases at a uniform rate of 2°c per hour
⇒5×2°C
⇒10°C
Now the temperature at 5 PM will be 38°C-10°C=28°C

HI PLEASE ANSWER BEFORE 12:00a.m. EST
Answer:
D
Step-by-step explanation:
Amanda's unit rate would be
s=50m
while Mary's is
s=60m
60-50 is 10, meaning the answer would be D.
Mary saves $10 more than Amanda every month.
Hope this helps! :)
Hi there!
We can find an equation that models Amanda's savings using the equation:
y = km, where:
k = rise / run (Amount/months)
Plug in a set of values from the table:
k = 100/2 = 50
y = 50m
We know that Mary saves y = 60m dollars a month, so we can determine the correct comparison by plugging in a value of 1 month into both equations:
Amanda:
y = 50(1) = $50
Mary:
y = 60(1) = $60
The difference between Mary's and Amanda's savings is $60 - $50 = $10, so each month, Mary saves $10 more than Amanda.
The correct answer is D.

Answer:
2/5
Step-by-step explanation:
40 and 100 can both be divided by 20. 40 divided by 20 equals 2 and 100 divided by 20 equals 5
Answer:
2/5 (0.4)
Step-by-step explanation:
We can reduce this by first looking at the fraction. [tex]\frac{40}{100}[/tex]
We can first divide by 10 on both sides to get a better number: [tex]\frac{4}{10}[/tex]
We can simplify both by 2 since thats another common number: [tex]\frac{2}{5}[/tex]
