Answer:
B, C, D, F
Step-by-step explanation:
to simplify the fraction 48/64, you need to divide both the numerator and denominator by their common factors. B is correct since you can divide both by 16, C is correct since both are divisible by 8, D is correct since both are divisible by 4, and F is correct since both are divisible by 2. A, however, would be correct only if the fraction were 64/48 and E would only be correct if 9 was a factor of 48 and 12 was a factor of 64, however neither haev such factors.
Darryl Dixon shoots an arrow at a zombie. The path of the arrow can be modeled with the equation y=-x^2 42x-80, where x is time in seconds and y is the height in feet. How long does it take for the arrow to reach its maximum?
We need to find time taken to reach arrow to its maximum.
The path of the arrow can be modeled with the equation [tex]y=-x^2+ 42x-80[/tex] .
Differentiating the given equation w.r.t x and equate it to zero.
[tex]\dfrac{dy}{dx}=-2x + 42 \\\\42 - 2x = 0\\\\x = 21\ seconds[/tex]
Putting value of x = 21 sec in given equation, we get :
[tex]y=-x^2+ 42x-80\\\\y = -(21)^2 + (42\times 21) - 80\\\\y = 361 \ feet[/tex]
Therefore, time taken to reach maximum height is 21 seconds.

If five times a number is subtracted from 27, the result is nine more than four times the number. Which equation can be used to find the value of the number?
A. 5(27 - x) = 9 + 4x
B. 27 - 5x = 4(9 + x)
C. 27 - 5x = 4x + 9
D.
5x - 27 = 9 + 4x
Answer:
C
Step-by-step explanation:
Listen, just think about it.
If 5 times “x” is subtracted from 27 (so 27-5x) if the result/answer
(meaning its equal “=“ ) is 9+ than 4 times “x” (soo basically like 4x +9). If you put all of those 2 equations together you get 27 x 5x = 4x + 9.
(I use “x” to as the variable and remember when a variable is next to a number it means you have to multiply whatever that number is)

Can someone please explain to me how to calculate your GPA and also on how to find out what your total grade points is... I stay confused
Answer:
Here is the explanation of how I was taught to do it :)
Step-by-step explanation: In its easiest form, an A=4, B=3, C=2, D=1, F=0.
If the class is 2 credit.......Multiply each numeric grade value by the number of credits the course was worth
Add these numbers together
Divide 45 by the total number of credits you took, in this example,13.
Your Weighted by Credit Hour GPA = 3.46
It depends on your school. Sorry this was not the most clear, I was taught like 2 years ago, and now I kinda forgot but hopefully this helps a lil dont get mad :)

If the width of a rectangle is 9 ft less then twice it’s length and the perimeter is 30 feet, what are the dimensions of the rectangle?
The dimension of the rectangle is,
The length of the rectangle is 7 feet.
And the width of the rectangle is 8 feet.
Given that,
If the width of a rectangle is 9 ft less than twice its length and the perimeter is 30 feet,
We have to determine,
What are the dimensions of the rectangle?
According to the question,
Let, the width of the rectangle is W,
And the length of a rectangle is L = 2W - 9,
The perimeter of the rectangle is = 2(L+W)
Where perimeter is 30 feet,
Therefore,
[tex]30 = 2(2W-9+W)\\\\30 = 2(3W-9)\\\\30 = 6W-18\\\\30 + 18 = 12W\\\\48 = 6W\\\\W = \dfrac{48}{6}\\\\W = 8 \ feet[/tex]
And the length of a rectangle is,
[tex]L = 2W - 9, \\\\L= 2(8) - 9\\\\L = 16-9 \\\\L =7 \ feet.[/tex]
Hence, The dimension of the rectangle is, the length of the rectangle is 7 feet, and the width of the rectangle is 8 feet.

What is the slope of a line that passes through the points (-2,4) and (-6, 12)?
-2
2
-1/2
1/2
Answer:
-2
Step-by-step explanation:
first, you want to graph your points on a graph. A really good online graphing calculator i like is called desmos.
next, slope is rise over run. count how many units up or down from leftmost point to the other. in this case it is -8.
third, find the run part of the slope by counting units right or left from the leftmost point to the other. in this case it is 4.
last, but the two numbers together in a fraction and simplify. rise over run.
-8/4 which simplifies to -2/1 which is the same thing as -2

plz help me
also good morning
Answer:
x=-24
Step-by-step explanation:
Answer:
It is -24.
Step-by-step explanation:
First distribute 2/3 on the left side, and distribute 1/2 on the other side. Now you have 1 /3 x + 8 = 1/ 6 x + 7 + (−3). Now, combine like terms. Now you should have 1 /3 x + 8 = 1 /6 x + 4. Now, subtract 1/6x on both sides. You should now have 1 /6 x + 8 = 4. Subtract 8 from both sides, and you should have 1/6x = -4. Now the last step is to multiply by 6 on both sides. Now you should get -24. Have a good day!
