3x + y = 5
y = -3x + 5 --- (y = mx + c)
m = -3 (slope)
so, perpendicular slope = 1/3
A boat is traveling at 43.2 m/s. It then goes down a faster part of the river and is now going 144
m/s which gave the boat an acceleration of 25.2 m/s2. How long did it take the boat to reach its
new speed?
Answer:
Step-by-step explanation:
boat was at 43.2 m/s speed increase to 144 m/s
if the boat was moving 0 m/s and increased to 144 m/s - 43.2 m/s accelerating at 25.2 m/s², it would take the same amount of time
25.2 m/s² × x seconds = (144 - 43.2) m/s solve for x in seconds
x seconds = 100.8 m/s / 25.2 m/s²
x seconds = 4 (m/s /ms²) = 4 (m/s × s²/m) = 4 seconds the units match
x = 4 seconds
The letters in the word JANUARY were put in a bag and drawn randomly. What is the probability of picking an a?
Answer: 2/7
Step-by-step explanation:
There are 7 letters in January, and 2 "a"s in order to find the probability, simply take 2/7. You can either leave it in the fraction form, or use the calculator, showing you have a 0.2857% chance of picking an "a"
2/7
there are 7 letters in jAnuAry and as you can see there are 2 A's so there is a 2/7 chance which is higher of a chance than the rest of the letters which are 1/7 each so it is most likely you would draw A although I can't fully say that because there is a 5/7 chance of drawing the other letters. Another way to say it is there is a 0.28571428571% chance of drawing A but there is a 0.71428571428% chance of drawing any other letter.
Hope this helps :3

Which equation represents the line that passes through the point (-3, 2) and has a slope of 2?
O y = 2x + 1
O
y = 2x - 4
O y = 2x - 7
y = 2x + 8
Answer:
y = 2x + 8
Step-by-step explanation:
To find the line, use the equation y = mx + b.
Plug in the slope and given point, then solve for b:
y = mx + b
2 = 2(-3) + b
2 = -6 + b
8 = b
Plug in the slope and b into the equation:
y = 2x + 8
So, the equation of the line is y = 2x + 8

Answer:
s = 2.5w + 10
Step-by-step explanation:
You have $10.00. Each week you save $2.50. The number of weeks you save w increases your savings s. Write an equation relating your savings s to the number of weeks you save w.
Your total savings (s) =
How many weeks you have been saving * how much you earn every week + the amount of money you already have.
So, the final equation should be:
w * 2.5 + 10 = s
Simplify.
s = 2.5w + 10

between AQRS and ATUV? Check all that apply.
Similar
Same Shape
They are Congruent and are Similar!
The descriptions that accurately describe the relationship between AQRS and ATUV is they are similar and congruent. The correct options are B and C.
What are congruent angles?Angles with the same measure are said to be congruent. In other words, two angles are congruent if they open to the same degree.
Two angles of 60 degrees, for example, are congruent because they have the same measure.
Similar angles are those that have the same shape but differ in size. In other words, two angles are similar if they are scaled by the same factor and have the same degree of opening.
Two angles of 60 degrees, for example, are similar because they have the same shape; however, if one of the angles is scaled to be twice as large as the other, they remain similar angles.
Thus, as per the given image, the correct options are B and C.

The volume of a cube is 216 cubic meters. What is the length (in meters) of one edge of the cube?
Answer: 6 meters
Step-by-step explanation: 6 is also what we call a cube root of a number. A cube root is a number you multiply by itself 3 times to get the product.
6 times 6 equals 36. 36 times 6 equals 216.
(6 times 6 times 6 = 216)
AKS 19 -- Dan is driving with an average speed of s. He is driving a total distance of d. What formula represents the total time of his trip? Question 2 options: t=ds t = d s t=ds t=d-s t=sd
Answer:
[tex]t=\dfrac{d}{s}[/tex]
Step-by-step explanation:
Dan is driving with an average speed of s. He is driving a total distance of d.
The average speed of an object is given by :
Average speed = total distance/total time
Let b the time of his trip
So,
[tex]s=\dfrac{d}{t}\\\\or\\\\t=\dfrac{d}{s}[/tex]
So, the formula for the total time of his trip is [tex]\dfrac{d}{s}[/tex].
