Answer:
45
Step-by-step explanation:
-3=t/-15
t=-3*-15
t=45
Answer:
t=45
Step-by-step explanation:
-3 = t/-15
-3(-15) = t/-15(-15) (multiply each side by -15 to get t by itself)
45 = t (Simplify)
A tram has an initial velocity of 300m/minute ◦ It travels a distance of 0.5km in 20 seconds
◦ What is the acceleration of the tram in m/s2?
If you could please help me, it would be greatly appreciated?
Answer:
Step-by-step explanation:
[tex]d=vt-\frac{at^2}{2} \\ \\ a=\frac{2(d-vt)}{t^2} \\ \\ a=\frac{2(500-300(20)}{20^2} \\ \\ a=-27.5 \frac{m}{s^2}[/tex]
The acceleration of the tram is 1 m/s^2.
To find the acceleration of the tram, we can use the following equation:
acceleration (a) = (change in velocity) / (time taken)
First, let's convert the initial velocity to m/s:
Initial velocity = 300 m/minute
To convert to m/s, we need to divide by 60 (since there are 60 seconds in a minute):
Initial velocity = 300 m/minute ÷ 60 seconds/minute = 5 m/s
Now, let's find the final velocity. The tram travels a distance of 0.5 km in 20 seconds.
Distance traveled = 0.5 km = 500 m (since 1 km = 1000 m)
Time taken = 20 seconds
Now, we can find the final velocity (v) using the formula:
v = (change in distance) / (time taken)
v = 500 m / 20 seconds = 25 m/s
Next, we can find the change in velocity:
change in velocity = final velocity - initial velocity
change in velocity = 25 m/s - 5 m/s = 20 m/s
Finally, we can calculate the acceleration:
acceleration (a) = (change in velocity) / (time taken)
acceleration (a) = 20 m/s / 20 seconds = 1 m/s^2
So, the acceleration of the tram is 1 m/s^2.

Hey guys I need your help on this!!
Answer:
Domain: (-∞, ∞) or All Real Numbers
Range: (0, ∞)
Asymptote: y = 0
As x ⇒ -∞, f(x) ⇒ 0
As x ⇒ ∞, f(x) ⇒ ∞
Step-by-step explanation:
The domain is talking about the x values, so where is x defined on this graph? That would be from -∞ to ∞, since the graph goes infinitely in both directions.
The range is from 0 to ∞. This where all values of y are defined.
An asymptote is where the graph cannot cross a certain point/invisible line. A y = 0, this is the case because it is infinitely approaching zero, without actually crossing. At first, I thought that x = 2 would also be an asymptote, but it is not, since it is at more of an angle, and if you graphed it further, you could see that it passes through 2.
The last two questions are somewhat easy. It is basically combining the domain and range. However, I like to label the graph the picture attached to help even more.
As x ⇒ -∞, f(x) ⇒ 0
As x ⇒ ∞, f(x) ⇒ ∞
10. A line with a negative slope and a negative
y-intercept is graphed on a coordinate
plane. Which quadrant will the line not pass
through? Justify your response.
Answer:
The line will not pass through the first quadrant.
Step-by-step explanation:
Since the y-intercept is negative, and the slope is negative, the line will start in the second quadrant, pass through the third quadrant to intercept the y-axis, then pass through the fourth quadrant. It will never touch the first quadrant.

PLEASE HELP!!
Answer:
AB ≈ 5.6 cm
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos62° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{AB}{BC}[/tex] = [tex]\frac{AB}{12}[/tex] ( multiply both sides by 12 )
12 × cos62° = AB , then

Answer:
8) interior angle = 160
9) x = 20
Step-by-step explanation:
8)
18-gon has 18 sides
The formula for sum of interior angles for an 18-gon is:
(18x180)-360 = 2880 degrees
2880 degrees / 18 angles = 160 degrees
9)
exterior angles = 360 degrees
360 = (3x-2)+(x+8)+(4x+9)+(2x-1)+(3x)+(4x+6)
360 = 3x-2+x+8+4x+9+2x-1+3x+4x+6
360 = 17x+20
17x = 340
x = 20 degrees

A family of 10 that all leave the house at the same time each morning has two bathrooms. They must share for everyone to be ready. Time is allotted to each family based on age. Is this apportionment or not apportionment?
Answer:
Not apportionment
Step-by-step explanation:
Apportionment can be described as a way of sharing out or dividing out in the best fair method.
If a family of 10 leave the house at the same time and have to share just two bathrooms, the time allocation should not be based on age rather should be based on how early each person wakes up in the morning.
If a gallon of milk costs $5.25 now and the price is
increasing 6% each year, how long before a gallon
of milk costs $12?
Answer: It will take approximately 21 years.
Step-by-step explanation:
6 percent of 5.25 is 0.315 (5.25 x 0.06 = 0.315)
Then you subtract 5.25 from 12 to calculate the number of years. (12 - 5.25 = 6.75)
Divide 0.315 from 6.75 (6.75 / 0.315 ≈ 21.4)

8 1/3
n>7
Answer:
6.65
Step-by-step explanation:
Answer:
n < 7 (n must be strictly less than 7)
so 4 and 6.65 can make this statement true
Step-by-step explanation:
28 > 4n
solve as if it is a normal equation,
divide both sides by 4
n < 7
n must be less than 7
so 4 and 6.65 are values that make the statement true

Sam needs 7 1/2 cups of orange juice to make punch for a group of her friends. She only has 5 1/3 cups. Write and solve an equation to represent how many more cups of orange juice Sam needs
Answer:
Equation is [tex]x+\frac{16}{3}=\frac{15}{2}[/tex] where [tex]x[/tex] denotes number of cups of orange juice needed by Sam.
[tex]x=\frac{13}{6}[/tex]
Step-by-step explanation:
Let [tex]x[/tex] denotes number of cups of orange juice needed by Sam.
Number of cups needed to make punch [tex]=7\frac{1}{2} =\frac{15}{2}[/tex]
Number of cups with Sam [tex]=5\frac{1}{3}=\frac{16}{3}[/tex]
Therefore,
[tex]x+\frac{16}{3}=\frac{15}{2}\\\\x= \frac{15}{2}-\frac{16}{3}\\\\x=\frac{45-32}{6}\\\\x=\frac{13}{6}[/tex]

Which expression is equivalent to the given expression? (2w-2)^3(8w6)
Answer:
Answer A=48
Step-by-step explanation:
Took the test got it right.
The expression (2w - 2)³ × (8w⁶) is equivalent to :
64w⁹ - 64w⁶ - 192w⁸ + 192w⁷.
What is expression?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.Given is the expression as -
(2w - 2)³ × (8w⁶)
The given expression is -
(2w - 2)³ × (8w⁶)
{2(w - 2)}³ × (8w⁶)
8(w - 1)³ × (8w⁶)
(a+b)³ = a³ - 3a²b + 3ab² - b³
So, on expanding, we will get -
8(w³ - 1 - 3w² + 3w) x (8w⁶)
(8w³ - 8 - 24w² + 24w )(8w⁶)
64w⁹ - 64w⁶ - 192w⁸ + 192w⁷
Therefore, the expression (2w - 2)³ × (8w⁶) is equivalent to :
64w⁹ - 64w⁶ - 192w⁸ + 192w⁷.
