Answer: 9 hrs for 45cm of snow to fall
Step-by-step
If 30cm = 6 hrs
Then divide 30/6 to get the unit rate of the amount of snow per hr
Which is 5/1
So 5cm per hr
Then add 30+5+5+5 to get 45
And since we know 5cm equal 1 hr
Add the original amount of hours which is 6 plus 3 ones
Which is 6+1+1+1
In total, it will take 9 hrs for 45cm of snow to fall.
i need help can some one help
Answer:
18/24 or 75%
Step-by-step explanation:
Okay so you already know that he got 16/24 which means that there were 8 questions that were wrong because 24-16= 8
So he has 16 points that we know of and 8 questions that he got wrong.
If he lost 1/4 of a point when he got it incorrect 1/4= 0.25
0.25 x 8 = 2points
So he got to points
16+ 2= 18 so now it is 18/24
If you have to show Out for 100% it would be 75%
Hope it helped!

Find a, R, and T.
a = 4, R = 147, T = 33
Step-by-step explanation:
find a
a/(a + 7) = (16/3)/(44/3)
a/(a + 7) = 16/44
44a = 16a + 112
44a - 16a = 112
28a = 112
a = 112/28
a = 4
find R
2x + 5 = 3x - 9
5 + 9 = 3x - 2x
14 = x
m ∠R = 180° - (2x + 5)
= 180 - (2(14) + 5)
= 180 - (28 + 5)
= 180 - 33
= 147°
find T
m ∠T = 3x - 9
= 3(14) - 9
= 42 - 9
= 33°
Simplify the expression to a + bi form:
(-5 – 3i) – (11 – 9i)
Answer: -16 + 6i
Step-by-step explanation:
(-5-3i) - (11-9i)
expand parentheses:
-5 - 3i - 11 + 9i
combine like terms:
-16 + 6i

plz help me with this im so confused
Answer:
1.) x = -5
y = -4
Point to graph: (-5, -4)
2.) x = 0
y = -6
Point to graph: (0, -6)
3.) x = 5
y = 8
Point to graph: (5, 8)
Step-by-step explanation:
Substitute x for the given value, then find y.
1.) -2(-5)-5y = 30
10-5y = 30
-5y = 20
y = -4
2.) -2(0)-5y = 30
-5y = 30
y = -6
3.) -2(5)-5y = 30
-10-5y = 30
-5y = 40
y = -8
Answer:
y values are
-4
-6
-8

write the correct equation
an equation of the parabola is y =__________
Answer:
Step-by-step explanation:
let the eq. of parabola be
y=ax²+bx+c
points (-1,0),(2,0),(3,4) and (0,-2) lie on it.
0=a-b+c
0=4a+2b+c
subtract
3a+3b=0
a=-b
4=9a+3b+c
-2=0+0+c
c=-2
a-b-2=0
-b-b-2=0
-2b-2=0
b+1=0
b=-1
a=-b=-(-1)=1
eq. of parabola is
y=x²-x-2

1. A line goes through the points (1, 6) and (–2, 8). Write the equation of the line in Point-Slope form. Show your work algebraically for full credit.
2. A line goes through the points (1, 6) and (–2, 8). Write the equation of the line in Slope-intercept form. Show your work algebraically for full credit. Hint: this is the same line as in #1.
Answer:
1) [tex]y-6=-\frac{2}{3} (x-1)[/tex] and 2) [tex]y=-\frac{2}{3} x+\frac{20}{3}[/tex]
Step-by-step explanation:
Ikr the bots are annoying.
Point-slope form is written as: [tex]y-y_1=m(x-x_1)[/tex]
Slope intercept form is written as: [tex]y=mx+b[/tex]
We also need to find the slope before putting it in this form, which can be done by [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
1) Points given are (1,6) and (-2,8)
Slope: [tex]m=\frac{8-6}{-2-1} =-\frac{2}{3}[/tex]
You can choose either of the two points to put into the formula. I just chose (1,6)
Answer: [tex]y-6=-\frac{2}{3} (x-1)[/tex]
2) Same points as before and we have the same slope as before. All we need is to find the y intercept which is our b in the equation. You can easily do this by plugging in a point and solving for b. I will choose point (1,6) again.
[tex]6=-\frac{2}{3} (1)+b[/tex]
[tex]6=-\frac{2}{3} +b[/tex]
[tex]6+\frac{2}{3}=-\frac{2}{3} +\frac{2}{3} +b[/tex]
[tex]b=6+\frac{2}{3}=\frac{20}{3}[/tex]
Answer: [tex]y=-\frac{2}{3} x+\frac{20}{3}[/tex]

Pablo is thinking of a number. When he doubles it and then adds 13 the resulting answer is 5.Construct an equation and solve it to determine the number Pablo is thinking of.
Answer:
x×2+13=5
Step-by-step explanation:
We use x as the unknown number, and we just put what's in the word problem! The answer is in the question.
Equation Set-Up
x×2+13=5
Remember order of operations! (PEMDAS)
Then you solve the equation.
Because of PEMDAS, we know that multiplication is the first thing we have to do.
x×2=2x
So now, our equation looks like this.
2x+13=5
We subtract 13 from the +13 to cancel it out, but that means that we also have to subtract 13 from the 5 on the other side. We are now left with this.
2x=-8
Then, we divide -8 by 2, which gives us...
x=-4
Pablo's number is -4.
I hope I helped! Have a great day.
