You can use cubes to help you write an expression and model the problem by using the cubes in replace of numbers. It should be a lot easier. Then after you finish you just have to write it down. There are other ways, but this is just one.
Answer:
r = x/n
Step-by-step explanation:
Solve for r:
x/r = n
Take the reciprocal of both sides:
r/x = 1/n
Multiply both sides by x:
Answer: r = x/n
Vertex of x^2 = (0,0)
Vertex of x^2 - 8x + 7
Find the roots by factoring
(x - 7)( x -1 )=0
x= 7, x = 1
middle: [7+1]/2 = 8/2 = 4
g(4) = 4^2 -8(4) + 7 = 16 - 32 + 7 = -9
Vertex = (4,-9)
Then the translation is right 4, down 9. This is the first option.
Answer:6 0
Step-by-step explanation:
Answer:
Yes, there enough tubes for each student to make their rocket.
Step-by-step explanation:
Given - In a course of 37 students they propose to make a rocket with recycled material, in order to make the rockets, in the course there are 151 cardboard tubes that were collected in a recyclable day.
To find - If 4 cardboard tubes are needed to make a rocket, are there enough tubes for each student to make their rocket ?
Proof -
Given that,
1 rocket is made with 4 cardboard tubes
Total cardboard tubes = 151
Now,
1 student will make 1 rocket
Total students = 37
⇒Total rockets made by the course = 37
Now,
1 rocket used 4 cardboard tubes
⇒37 rocket used 37×4 cardboard tubes
⇒37 rocket used 148 cardboard tubes.
As
148 < 151
⇒There are enough tubes for each student to make their rocket.
