Denise has 3 hours to spend training for an upcoming race. She completes her training by running full speed the distance of the race and walking back the same distance to cool down. If she runs at a speed of 8mph and walks back at a speed of 2mph, how long should she plan to spend walking back?
Answers
Answer:
Denise should plan to spend 36 minutes walking back.
Step-by-step explanation:
Let 'x' reflect the amount of time spent running in hours, then 3-x represents the time spent walking in hours.
here , we know,
[tex]Distance= Speed \times time[/tex]
Given the values ,
[tex]Distance= 8x[/tex]
[tex]speed=2mph[/tex]
[tex]Time=(3-x)hours[/tex]
Now , putting these values ,
[tex]8x=2(3-x)[/tex]
[tex]8x=6-2x[/tex]
[tex]10x=6[/tex]
[tex]x=\frac{6}{10}[/tex]
[tex]x=\frac{3}{5}[/tex]
[tex]\frac{3}{5} \times 60[/tex] = 36minutes (converting hours into minutes that is 1 hour = 60 minutes )
Hence , the answer is 36 minutes .

Paula knits hats. The number of hats h she can knit varies directly with the amount of yarn (y) in yards she has. The constant of proportionality is 42. Write an equation to represent the relationship between the number of yards of yarn Paula has and the number of hats she can knit.
Answers
Answer:
The equation showing the relationship between the number of yards of yarn Paula has and the number of hats she can knit is ;
h = 42y
Step-by-step explanation:
Here, we want to write an equation;
From the question, we are told that the number of hats h that can be knitted is directly proportional to the amount of yarn in yards
Since it is a proportional relationship;
h = k * y
where k is the constant of proportionality given as 42
Hence;
h = 42 * y
h = 42y

Evaluate 3ab for a=2 and b=3
Answers
Answer:
18
Step-by-step explanation:
For this problem, we will simply plug in the values of a and b into the respective variables in the expression 3ab to "evaluate" the expression.
a = 2; b = 3
3ab
Note, that when variables like a and b are smashed with a constant, the use of multiplication is in play.
3ab = 3 * a * b
With this in mind, let's plug in the values of a and b into the expression.
3ab
= 3 (2) (3)
= 3 (6)
= 18
Hence, 3ab evaluated when a=2 and b=3 is 18.
Cheers.

Mark Went to the store and purchase nine pairs of socks and three packages of undershirts for $8.28 each he also purchase a pair of pants for $32 he spent a total of $77.99 how much did he pay for each pair of socks write an equation using the variable S
Answers
Answer:
He paid $2.35 for each pair of socks.
An equation using the variable S is
$77.99 = 9S + (3 × $8.28) + $32
Step-by-step explanation:
Let S be the cost of a pair of socks
From the question, Mark purchase nine pairs of socks, that is, the total cost of the pairs of socks is 9S
He purchase three packages of undershirts for $8.28 each; the total cost of the three packages of shirt will be 3 × $8.28 = $24.84
and he also purchase a pair of pants for $32
Since he spent a total of $77.99, we can write that
$77.99 = 9S + (3 × $8.28) + $32
Now, we can determine S, the cost of a pair of socks
$77.99 = 9S + (3 × $8.28) + $32
$77.99 = 9S + $24.84 + $32
$77.99 = 9S + $56.84
9S = $77.99 - $56.84
9S = $21.15
S = $21.15/9
S = $2.35
Hence, he paid $2.35 for each pair of socks.
