Answer:

Maya solve puzzle in 6 minutes per puzzle and Amy solves the puzzle in 7 minutes per puzzle.

Step-by-step explanation:

Given:

For Maya 5 puzzles = 30 minutes

For Amy 4 puzzles = 28 minutes

We need to find the rate at which student solve the puzzle in minutes per puzzle.

Solution:

First we will find the rate of Maya.

5 puzzles = 30 minutes

1 puzzle = Number of minutes for 1 puzzle

By Using Unitary method we get;

Number of minutes for 1 puzzle = \frac{30}{5}=6\ mins

Hence Maya requires 6 minutes for 1 puzzle.

Now we will find the rate of Amy.

4 puzzles = 28 minutes

1 puzzle = Number of minutes for 1 puzzle

By Using Unitary method we get;

Number of minutes for 1 puzzle = \frac{28}{4}=7\ mins

Hence Maya requires 7 minutes for 1 puzzle.

Hence We can say that Maya solve puzzle in 6 minutes per puzzle and Amy solves the puzzle in 7 minutes per puzzle.

It takes Maya 30 minutes to solve 5 logic puzzles and it takes Amy 28 minutes to solve 4 logic puzzles use models to show the rate at which each student solves the puzzles in minutes per puzzle

Answer:

Maya's rate to solve the puzzle = 6 min/puzzle

Ame's rate to solve the puzzle = 7 min/puzzle

Step-by-step explanation:

Let x be the rate of the each student to solve the puzzle.

Given:

Maya takes time to solve 5 logic puzzles = 30 min

Ame takes time to solve 4 logic puzzles = 28 min

We need to find the rate of each student to solve the puzzle.

Solution:

For Maya:

Maya takes 30 minutes to solve 5 logic puzzles.

Suppose Maya solves x puzzles in one minute.

As per given statement Maya solves (5x) puzzles in 30 minutes, So we may write the equation as:

5x = 30

x = \frac{30}{5}

x = 6\ min/puzzle

Therefore, Maya solves each puzzles in 6 minutes.

For Ame:

Ame takes 28 minutes to solve 4 logic puzzles.

Suppose Ame solve x puzzles in one minute.

As per given statement Ame solve (4x) puzzles in 28 minutes, So we may write the equation as:

4x = 28

x = \frac{28}{4}

x = 7\ min/puzzle

Therefore, Ame solves each puzzles in 7 minutes.

Can I get help solving this graph please?
Daniel [21]
see the attached figure with the letters

1) find m(x) in the interval A,B
A (0,100)  B(50,40) -------------- > p=(y2-y1(/(x2-x1)=(40-100)/(50-0)=-6/5
m=px+b---------- > 100=(-6/5)*0 +b------------- > b=100
mAB=(-6/5)x+100

2) find m(x) in the interval B,C
B(50,40)  C(100,100) -------------- > p=(y2-y1(/(x2-x1)=(100-40)/(100-50)=6/5
m=px+b---------- > 40=(6/5)*50 +b------------- > b=-20
mBC=(6/5)x-20

3) find n(x) in the interval A,B
A (0,0)  B(50,60) -------------- > p=(y2-y1(/(x2-x1)=(60)/(50)=6/5
n=px+b---------- > 0=(6/5)*0 +b------------- > b=0
nAB=(6/5)x

4) find n(x) in the interval B,C
B(50,60)  C(100,90) -------------- > p=(y2-y1(/(x2-x1)=(90-60)/(100-50)=3/5
n=px+b---------- > 60=(3/5)*50 +b------------- > b=30
nBC=(3/5)x+30

5) find h(x) = n(m(x)) in the interval A,B
mAB=(-6/5)x+100
nAB=(6/5)x
then 
n(m(x))=(6/5)*[(-6/5)x+100]=(-36/25)x+120
h(x)=(-36/25)x+120
find <span>h'(x) 
</span>h'(x)=-36/25=-1.44

6) find h(x) = n(m(x)) in the interval B,C
mBC=(6/5)x-20
nBC=(3/5)x+30
then 
n(m(x))=(3/5)*[(6/5)x-20]+30 =(18/25)x-12+30=(18/25)x+18
h(x)=(18/25)x+18
find h'(x) 
h'(x)=18/25=0.72 

for the interval (A,B) h'(x)=-1.44
for the interval (B,C) h'(x)= 0.72

<span> h'(x) = 1.44 ------------ > not exist</span>
