A bamboo tree grew 3 in. Per day. Write and solve an equation to find how many days d it took the tree to grow 144 in. What is the equation
Answer:
144 divided by 3 = d (number of days)
Step-by-step explanation:
Answer:
Equation: 3d=144
Solution: 48 days
Step-by-step explanation:
Since it grown 3 in. per day and it grew 144 in.
U have to divide the 2 numbers
3d=144
d=144/3
d=48 days
(d=how many days)

What's the Constant of Proportianlity/Unit Rate?
Answer:
1/3 cup of juice per cup of berries
Step-by-step explanation:
The table shows that if we go from 0 to 4 cups (a "run" of 4 cups), the juice output is 1 1/3 (or 4/3) (a "rise" of 4/3 cups), and so the desired constant of proportionality is the unit rate
(4/3) cups
------------------------ = 1/3 cup of juice per cup of berries
4 cups berries

Step-by-step explanation:
Write a formula that will compute the final grade for the course, using G to represent the final grade, H to represent the homework average, Q to represent the quiz average, P to represent the project grade, T to represent the test average, and F to represent the final exam grade. Note: Keep in mind how you must write the percentages that show the weighting of each category when doing computations!
Answer:
To calculate final grade we use the formula:
Final grade = H( the weight of h) + Q( the weight of q) + P (the weight of project) +T (the weight of test) + F(the weight of final exams).
This formula help us to calculate the grade we need to get.
Step-by-step explanation:
Solution:
Suppose grade breakdown for certain college course is as follow:
Homework = 15%
Quizzes = 20%
Project = 10%
Test = 40%
Final exam= 15%
Let G represent the final grade
H represents homework average,
Q represents quizzes and P represent project, T represent test average and F represent final exam.
To calculate final grade we use the formula:
Final grade = H( the weight of h) + Q( the weight of q) + P (the weight of project) +T (the weight of test) + F(the weight of final exams).
This formula help us to calculate the grade we need to get.
Fabio is driving west away from Albany and towards Buffalo along Interstate 90 at a constant rate of speed
of 62 miles per hour. After driving for 1.5 hours, Fabio is 221 miles from Albany.
Answer:
a) ( D - 128 ) = m ( 1,5 - 0)
b) D = 62*h + 128
Step-by-step explanation:
Fabio drives at a constant speed of 62 miles per hour therefore:
62 * 1,5 = 93 miles
But he is 221 miles away from Albany, then he started
221 - 93 = 128 miles from Albany
In a coordinates system D (distance in the y-axis ), and h ( hours in x-axis), we have two points
h₁ = 0 (h) D (y intercept) = 128 miles and h = 1,5 (h) D = 221 miles
P₁ ( 0 , 128 ) P₂ ( 1,5 , 221 )
Then the equation for straight-line passing through two points is:
m = ( D - D₁ ) / ( h - h₁ )
( D - D₁ ) = m ( h - h₁ )
a) ( D - 128 ) = m ( 1,5 - 0)
And
b) m = 93/ 1,5
m = 62
And
b) D = mh + b
D = mh + D₁
D = 62*h + 128
a)
The equation is:
[tex]D - 221 = 62(h - 1.5)[/tex]
b) Initially, he was 128 miles away from Albany.
Item a:
Fabio is traveling from Albany to Buffalo, and his distance D from Albany after h hours is modeled by a linear function in the following format:
[tex]D - D_1 = m(h - h_1)[/tex]
We have that:
Velocity of 62 miles per hour, thus the slope is [tex]m = 62[/tex].After 1.5 hours, he is 221 miles away from Albany, thus the point is [tex]h_1 = 1.5, D_1 = 221[/tex].The equation is:
[tex]D - D_1 = m(h - h_1)[/tex]
[tex]D - 221 = 62(h - 1.5)[/tex]
Item b:
The initial distance is D when h = 0, so:[tex]D - 221 = 62(0 - 1.5)[/tex]
[tex]D = -1.5(62) + 221[/tex]
[tex]D = 128[/tex]
Initially, he was 128 miles away from Albany.

Answer:
(x+5)(x+5)
Step-by-step explanation:
Let's arrange it in a proper manner first of all.
x² + 10x + 25Step: Spilt 10x in order to factorize it.
x² + 10x + 25
0r, x² + 5x + 5x + 25
Step: Make two pairs from equation
x² + 5x + 5x + 25
0r, x(x+5) + 5(x+5)
Step: Take common thing from the given equation
x(x+5) + 5(x+5)
0r, (x+5)(x+5)
Hence, (x+5) and (x+5) are the factor for the given equation.

b. 229
c. 172
d. 171
Answer:
I think its 229
if you take how many yellow marbles he got out of 7 it would be 3/7 and then I divided 400 by 7 and got 57. something so I multiplied 3 times 57 and got 171. So if you take 400-171 you get 229
